device description 56f8322 technical data, rev. 10.0 freescale semiconductor 7 preliminary 1.1.5 energy information ? fabricated in high-density cmos with 5v-tolerant, ttl-compatible digital inputs ? on-board 3.3v down to 2.6v voltage regulator for powering internal logic and memories ? on-chip regulators for digital and analog circuitry to lower cost and reduce noise ? wait and stop modes available ? adc smart power management ? each peripheral can be individually disabled to save power 1.2 device description the 56f8322 and 56f8122 are members of the 56800e core-based family of hybrid controllers. each combines, on a single chip, the processing power of a digital signal processor (dsp) and the functionality of a microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. because of their low cost, configuration flexibility, and compact program code, the 56f8322 and 56f8122 are well-suited for many applications. these devices include many peripherals that are especially useful for automotive control (56f8322 only); industrial control and networking; motion control; home appliances; general purpose inverters; smart sensors; fire and security systems; power management; and medical monitoring applications. the 56800e core is based on a harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. the mcu-style programming model and optimized instruction set allow straightforward generation of efficient, compact dsp and control code. the instruction set is also highly efficient for c compilers to enable rapid development of optimized control applications. the 56f8322 and 56f8122 support program execution from internal memories. two data operands can be accessed from the on-chip data ram per instruction cycle. these devices also provide one external dedicated interrupt line and up to 21 general purpose input/output (gpio) lines, depending on peripheral configuration. 1.2.1 56f8322 features the 56f8322 hybrid controller includes 32kb of program flash and 8kb of data flash, each programmable through the jtag port, and 4kb of program ram and 8kb of data ram. a total of 8kb of boot flash is incorporated for easy customer inclusion of field-programmable software routines that can be used to program the main program and data flash memory areas. both program and data flash memories can be independently bulk erased or erased in pages. program flash page erase size is 1kb. boot and data flash page erase size is 512 bytes. the boot flash memory can also be either bulk or page erased. a key application-specific feature of the 56f8322 is the inclusion of one pulse width modulator (pwm) module. this module incorporates three complementary, individually programmable pwm signal output pairs and is also capable of supporting six independent pwm functions to enhance motor control functionality. complementary operation permits programmable dead time insertion, distortion correction via current sensing by software, and separate top and bottom output polarity control. the up-counter value
56f8322 techncial data, rev. 10.0 8 freescale semiconductor preliminary is programmable to support a continuously variable pwm frequency. edge-aligned and center-aligned synchronous pulse width control (0% to 100% modulation) is supported. the device is capable of controlling most motor types: acim (ac induction motors); both bdc and bldc (brush and brushless dc motors); srm and vrm (switched and variable reluctance motors); and stepper motors. the pwm incorporates fault protection and cycle-by-cycle current limiting with sufficient output drive capability to directly drive standard optoisolators. a smoke-inhibit, write-once protection feature for key parameters is also included. a patented pwm waveform distortion correction circuit is also provided. each pwm is double-buffered and includes interrupt controls to permit integral reload rates to be programmable from 1/2 (center-aligned mode only) to 16. the pwm module provides reference outputs to synchronize the analog-to-digital converters (adcs) through quad timer c, channel 2. the 56f8322 incorporates one quadrature decoder capable of capturing all four transitions on the two-phase inputs, permitting generation of a number proportional to actual position. speed computation capabilities accommodate both fast- and slow-moving shafts. an integrated watchdog timer in the quadrature decoder can be programmed with a time-out value to alarm when no shaft motion is detected. each input is filtered to ensure only true transitions are recorded. this hybrid controller also provides a full set of standard programmable peripherals that include two serial communications interfaces (scis), two serial peripheral interfaces (spis), two quad timers and flexcan. any of these interfaces can be used as general purpose input/outputs (gpios) if that function is not required. a flex controller area network interface (can version 2.0 b-compliant) and an internal interrupt controller are also a part of the 56f8322. 1.2.2 56f8122 features the 56f8122 hybrid controller includes 32kb of program flash, programmable through the jtag port, and 8kb of data ram. a total of 8kb of boot flash is incorporated for easy customer inclusion of field-programmable software routines that can be used to program the main program flash memory area. the program flash memory can be independently bulk erased or erased in pages; program flash page erase size is 1kb. the boot flash memory can also be either bulk or page erased. this hybrid controller also provides a full set of standard programmable peripherals that include two serial communications interfaces (scis), two serial peripheral interfaces (spis), and two quad timers. any of these interfaces can be used as general purpose input/outputs (gpios) if that function is not required. an internal interrupt controller is also a part of the 56f8122. 1.3 award-winning development environment processor expert tm (pe) provides a rapid application design (rad) tool that combines easy-to-use component-based software application creation with an expert knowledge system. the codewarrior integrated development environment is a sophisticated tool for code navigation, compiling, and debugging. a complete set of evaluation modules (evms), demonstration board kit and development system cards will support concurrent engineering. together, pe, codewarrior and evms create a complete, scalable tools solution for easy, fast, and efficient development.
architecture block diagram 56f8322 technical data, rev. 10.0 freescale semiconductor 9 preliminary 1.4 architecture block diagram note: features in italics are not available in the 56f8122 device and are shaded in the following figures. the 56f8322/56f8122 architecture is shown in figure 1-1 and figure 1-2 . figure 1-1 illustrates how the 56800e system buses communicate with internal memories and the ipbus bridge. table 1-2 lists the internal buses in the 56800e architecture and provides a brief description of their function. figure 1-2 shows the peripherals and control blocks connected to the ipbus bridge. the figures do not show the on-board regulator and power and ground signals. they also do not show the multiplexing between peripherals or the dedicated gpios. please see part 2 signal/connection descriptions , to see which signals are multiplexed with those of other peripherals. also shown in figure 1-2 are connections between the pwm , timer c and adc blocks. these connections allow the pwm and/or timer c to control the timing of the start of adc conversions. the timer c, channel 2, output can generate periodic start (sync) signals to the adc to start its conversions. in another operating mode, the pwm load interrupt (sync output) signal is routed internally to the timer c, channel 2, input as indicated. the timer can then be used to introduce a controllable delay before generating its output signal. the timer output then triggers the adc. to fully understand this interaction, please see the 56f8300 peripheral user manual for clarification on the operation of all three of these peripherals.

56f8322 techncial data, rev. 10.0 28 freescale semiconductor preliminary 3.3 use of on-chip relaxation oscillator an internal relaxtion oscillator can supply the reference frequency when an external frequency source of crystal is not used. during a boot or reset sequence, the relaxation oscillator is enabled by default, and the precs bit in the pllcr word is set to 0. if an external oscillator is connected, the relaxation oscillator can be deselected instead by setting the precs bit in the pllcr to 1. if a changeover between internal and external oscillators is required at start up, internal device circuits compensate for any asynchronous transitions between the two clock signals so that no glitches occur in the resulting master clock to the chip. when changing clocks, the user must ensure that the clock source is not switched until the desired clock is enabled and stable. to compensate for variances in the device manufacturing process, the accuracy of the relaxation oscillator can be incrementally adjusted to within + 0.1% of 8mhz by trimming an internal capacitor. bits 0-9 of the osctl (oscillator control) register allow the user to set in an additional offset (trim) to this preset value to increase or decrease capacitance. upon power-up, the default value of this trim is 512 units. each unit added or deleted changes the output frequency by about 0.1%, allowing incremental adjustment until the desired frequency accuracy is achieved. the internal oscillator is calibrated at the factory to 8mhz and the trim value is stored in the flash information block and loaded to the fmopt1 register at reset. when using the relaxation oscillator, the boot code should read the fmopt1 register and set this value as osctl trim. for further information, see the 56f8300 peripheral user manual . 3.4 internal clock operation at reset, both oscillators will be powered up; however, the relaxation oscillator will be the default clock reference for the pll. software should power down the block not being used and program the pll for the correct frequency.

56f8322 techncial data, rev. 10.0 52 freescale semiconductor preliminary 4.8 factory-programmed memory the boot flash memory block is programmed during manufacturing with a default serial bootloader program. the serial bootloader application can be used to load a user application into the program and data flash ( not available on the 56f8122 ) memories of the device. the 56f83xx sci/can bootloader user manual provides detailed information on this firmware. an application note, production flash programming , details how the serial bootloader program can be used to perform production flash programming of the on-board flash memories as well as other optional methods. like all the flash memory blocks, the boot flash can be erased and programmed by the user. the serial bootloader application is programmed as an aid to the end user, but is not required to be used or maintained in the boot flash memory. part 5 interrupt controller (itcn) 5.1 introduction the interrupt controller (itcn) module is used to arbitrate between various interrupt requests (irqs), to signal to the 56800e core when an interrupt of sufficient priority exists, and to what address to jump in order to service this interrupt. 5.2 features the itcn module design includes these distinctive features: ? programmable priority levels for each irq ? two programmable fast interrupts ? notification to sim module to restart clocks out of wait and stop modes ? drives initial address on the address bus after reset for further information, see table 4-3 , interrupt vector table contents. 5.3 functional description the interrupt controller is a slave on the ipbus. it contains registers allowing each of the 82 interrupt sources to be set to one of four priority levels, excluding certain interrupts of fixed priority. next, all of the interrupt requests of a given level are priority encoded to determine the lowest numerical value of the active interrupt requests for that level. within a given priority level, 0 is the highest priority, while number 81 is the lowest. 5.3.1 normal interrupt handling once the itcn has determined that an interrupt is to be serviced and which interrupt has the highest priority, an interrupt vector address is generated. normal interrupt handling concatenates the vba and the vector number to determine the vector address. in this way, an offset is generated into the vector table for each interrupt.
functional description 56f8322 technical data, rev. 10.0 freescale semiconductor 53 preliminary 5.3.2 interrupt nesting interrupt exceptions may be nested to allow an irq of higher priority than the current exception to be serviced. the following tables define the nesting requirements for each priority level. 5.3.3 fast interrupt handling fast interrupts are described in the dsp56800e reference manual . the interrupt controller recognizes fast interrupts before the core does. a fast interrupt is defined (to the itcn) by: 1. setting the priority of the interrupt as level 2, with the appropriate field in the ipr registers 2. setting the fimn register to the appropriate vector number 3. setting the fivaln and fivahn registers with the address of the code for the fast interrupt when an interrupt occurs, its vector number is compared with the fim0 and fim1 register values. if a match occurs, and it is a level 2 interrupt, the itcn handles it as a fast interrupt. the itcn takes the vector address from the appropriate fivaln and fivahn registers, instead of generating an address that is an offset from the vba. the core then fetches the instruction from the indicated vector adddress and if it is not a jsr, the core starts its fast interrupt handling. table 5-1 interrupt mask bit definition sr[9] 1 1. core status register bits indicating current interrupt mask within the core. sr[8] 1 permitted exceptions masked exceptions 0 0 priorities 0, 1, 2, 3 none 0 1 priorities 1, 2, 3 priority 0 1 0 priorities 2, 3 priorities 0, 1 1 1 priority 3 priorities 0, 1, 2 table 5-2. interrupt priority encoding ipic_level[1:0] 1 1. see ipic field definition in section 5.6.30.2 current interrupt priority level required nested exception priority 00 no interrupt or swilp priorities 0, 1, 2, 3 01 priority 0 priorities 1, 2, 3 10 priority 1 priorities 2, 3 11 priorities 2 or 3 priority 3

resets 56f8322 technical data, rev. 10.0 freescale semiconductor 77 preliminary 5.7 resets 5.7.1 reset handshake timing the itcn provides the 56800e core with a reset vector address whenever reset is asserted. the reset vector will be presented until the second rising clock edge after reset is released. 5.7.2 itcn after reset after reset, all of the itcn registers are in their default states. this means all interrupts are disabled, except the core irqs with fixed priorities: ? illegal instruction ? sw interrupt 3 ? hw stack overflow ? misaligned long word access ? sw interrupt 2 ? sw interrupt 1 ? sw interrupt 0 ? sw interrupt lp these interrupts are enabled at their fixed priority levels. part 6 system integration module (sim) 6.1 introduction the sim module is a system catchall for the glue logic that ties together the system-on-chip. it controls distribution of resets and clocks and provides a number of control features. the system integration module is responsible for the following functions: ? reset sequencing ? clock control & distribution ? stop/wait control ? pull-up enables for selected peripherals ? system status registers ? registers for software access to the jtag id of the chip ? enforcing flash security these are discussed in more detail in the sections that follow.
56f8322 techncial data, rev. 10.0 78 freescale semiconductor preliminary 6.2 features the sim has the following features: ? flash security feature prevents unauthorized access to code/data contained in on-chip flash memory ? power-saving clock gating for peripherals ? three power modes (run, wait, stop) to control power utilization stop mode shuts down the 56800e core, system clock, and peripheral clock stop mode entry can optionally disable pll and oscillator (low power vs. fast restart) wait mode shuts down the 56800e core and unnecessary system clock operation run mode supports full part operation ? controls to enable/disable the 56800e core wait and stop instructions ? controls reset sequencing after reset ? software-initiated reset ? four 16-bit registers reset only by a power-on reset usable for general purpose software control ? system control register ? registers for software access to the jtag id of the chip 6.3 operating modes since the sim is responsible for distributing clocks and resets across the chip, it must understand the various chip operating modes and take appropriate action. these are: ? reset mode, which has two submodes: total reset mode C 56800e core and all peripherals are reset core-only reset mode C 56800e core in reset, peripherals are active C this mode is required to provide the on-chip flash interface module time to load data from flash into fm registers ? run mode this is the primary mode of operation for this device. in this mode, the 56800e controls chip operation. ? debug mode the 56800e is controlled via jtag/eonce when in debug mode. all peripherals, except the cop and pwms, continue to run. cop is disabled and pwm outputs are optionally switched off to disable any motor from being driven; see the pwm chapter in the 56f8300 peripheral user manual for details. ? wait mode in wait mode, the core clock and memory clocks are disabled. optionally, the cop can be stopped. similarly, it is an option to switch off pwm outputs to disable any motor from being driven. all other peripherals continue to run. ? stop mode 56800e, memory and most peripheral clocks are shut down. optionally, the cop and can can be stopped. for lowest power consumption in stop mode, the pll can be shut down. this must be done explicitly before entering stop mode, since there is no automatic mechanism for this. the can (along with any non-gated interrupt) is capable of waking the chip up from stop mode, but is not fully functional in stop mode.

56f8322 techncial data, rev. 10.0 92 freescale semiconductor preliminary 6.8 stop and wait mode disable function figure 6-16 internal stop disable circuit the 56800e core contains both stop and wait instructions. both put the cpu to sleep. for lowest power consumption in stop mode, the pll can be shut down. this must be done explicitly before entering stop mode, since there is no automatic mechanism for this. when the pll is shut down, the 56800e system clock must be set equal to the prescaler output. some applications require the 56800e stop and wait instructions be disabled. to disable those instructions, write to the sim control register (sim_control) described in section 6.5.1 . this procedure can be on either a permanent or temporary basis. permanently assigned applications last only until their next reset. 6.9 resets the sim supports four sources of reset. the two asynchronous sources are the external reset pin and the power-on reset (por). the two synchronous sources are the software reset, which is generated within the sim itself, by writing to the sim_control register, and the cop reset. reset begins with the assertion of any of the reset sources. release of reset to various blocks is sequenced to permit proper operation of the device. a por reset is declared when reset is removed and any of the three voltage detectors (1.8v por, 2.2v core voltage, or 2.7v i/o voltage) indicate a low supply voltage condition. por will continue to be asserted until all voltage detectors indicate a stable supply is available (note that as power is removed por is not declared until the 1.8v core voltage threshold is reached.) a por reset is then extended for 64 clock cycles to permit stabilization of the clock source, followed by a 32 clock window in which sim clocking is initiated. it is then followed by a 32 clock window in which peripherals are released to implement flash security, and, finally, followed by a 32 clock window in which the core is initialized. after completion of the described reset sequence, application code will begin execution. resets may be asserted asynchronously, but are always released internally on a rising edge of the system clock. d-flop dq c d-flop d q c r 56800e stop_dis permanent disable reprogrammable disable clock select reset d note: wait disable circuit is similar
operation with security enabled 56f8322 technical data, rev. 10.0 freescale semiconductor 93 preliminary part 7 security features the 56f8322/56f8122 offer security features intended to prevent unauthorized users from reading the contents of the flash memory (fm) array. the flash security consists of several hardware interlocks that block the means by which an unauthorized user could gain access to the flash array. however, part of the security must lie with the users code. an extreme example would be users code that dumps the contents of the internal program, as this code would defeat the purpose of security. at the same time, the user may also wish to put a backdoor in his program. as an example, the user downloads a security key through the sci, allowing access to a programming routine that updates parameters stored in another section of the flash. 7.1 operation with security enabled once the user has programmed the flash with his application code, the device can be secured by programming the security bytes located in the fm configuration field, which occupies a portion of the fm array. these non-volatile bytes will keep the part secured through reset and through power-down of the device. only two bytes within this field are used to enable or disable security. refer to the flash memory chapter in the 56f8300 peripheral user manual for the state of the security bytes and the resulting state of security. when flash security mode is enabled in accordance with the method described in the flash memory module specification, the device will disable the core eonce debug capabilities. normal program execution is otherwise unaffected. 7.2 flash access blocking mechanisms the 56f8322/56f8122 have several operating functional and test modes. effective flash security must address operating mode selection and anticipate modes in which the on-chip flash can be compromised and read without explicit user permission. methods to block these are outlined in the next subsections. 7.2.1 forced operating mode selection at boot time, the sim determines in which functional modes the device will operate. these are: ? unsecured mode ? secure mode (eonce disabled) when flash security is enabled as described in the flash memory module specification, the device will disable the eonce debug interface. 7.2.2 disabling eonce access on-chip flash can be read by issuing commands across the eonce port, which is the debug interface for the 56800e cpu. the trst , tclk, tms, tdo, and tdi pins comprise a jtag interface onto which the eonce port functionality is mapped. when the device boots, the chip-level jtag tap (test access port) is active and provides the chips boundary scan capability and access to the id register.
56f8322 techncial data, rev. 10.0 94 freescale semiconductor preliminary proper implementation of flash security requires that no access to the eonce port is provided when security is enabled. the 56800e core has an input which disables reading of internal memory via the jtag/eonce. the fm sets this input at reset to a value determined by the contents of the fm security bytes. 7.2.3 flash lockout recovery if a user inadvertently enables flash security on the device, a built-in lockout recovery mechanism can be used to reenable access to the device. this mechanism completely reases all on-chip flash, thus disabling flash security. access to this recovery mechanism is built into codewarrior via an instruction in memory configuration ( .cfg ) files. add, or uncomment the following configuration command: unlock_flash_on_connect 1 for more information, please see codewarrior mc56f83xx/dsp5685x family targeting manual . the lockout_recovery instruction has an associated 7-bit data register (dr) that is used to control the clock divider circuit within the fm module. this divider, fm_clkdiv[6:0], is used to control the period of the clock used for timed events in the fm erase algorithm. this register must be set with appropriate values before the lockout sequence can begin. refer to the 56f8300 peripheral user manual for more details on setting this register value. the value of the jtag fm_clkdiv[6:0] will replace the value of the fm register fmclkd that divides down the system clock for timed events, as illustrated in figure 7-1 . fm_clkdiv[6] will map to the prdiv8 bit, and fm_clkdiv[5:0] will map to the div[5:0] bits. the combination of prdiv8 and div must divide the fm input clock down to a frequency of 150khz-200khz. the writing the fmclkd register section in the flash memory chapter of the 56f8300 peripheral user manual gives specific equations for calculating the correct values. figure 7-1 jtag to fm connection for lockout recovery two examples of fm_clkdiv calculations follow. sys_clk jtag fmclkd divider 7 7 7 2 fmclkdiv fmerase flash memory clock input
flash access blocking mechanisms 56f8322 technical data, rev. 10.0 freescale semiconductor 95 preliminary example 1: if the system clock is the 8mhz crystal frequency because the pll has not been set up, the input clock will be below 12.8mhz, so prdiv8=fm_clkdiv[6]=0. using the following equation yields a div value of 19 for a clock of 200khz, and a div value of 20 for a clock of 190khz. this translates into an fm_clkdiv[6:0] value of $13 or $14, respectively. example 2: in this example, the system clock has been set up with a value of 32mhz, making the fm input clock 16mhz. because that is greater than 12.8mhz, prdiv8=fm_clkdiv[6]=1.using the following equation yields a div value of 9 for a clock of 200khz, and a div value of 10 for a clock of 181khz. this translates to an fm_clkdiv[6:0] value of $49 or $4a, respectively. once the lockout_recovery instruction has been shifted into the instruction register, the clock divider value must be shifted into the corresponding 7-bit data register. after the data register has been updated, the user must transition the tap controller into the run-test/idle state for the lockout sequence to commence. the controller must remain in this state until the erase sequence has completed. for details, see the jtag section in the 56f8300 peripheral user manual . note: once the lockout recovery sequence has completed, the user must reset both the jtag tap controller (by asserting trst ) and the device (by asserting external chip reset) to return to normal unsecured operation. 7.2.4 product analysis the recommended method of unsecuring a programmed device for product analysis of field failures is via the backdoor key access. the customer would need to supply technical support with the backdoor key and the protocol to access the backdoor routine in the flash. additionally, the keyen bit that allows backdoor key access must be set. an alternative method for performing analysis on a secured microcontroller would be to mass-erase and reprogram the flash with the original code, but modify the security bytes. to insure that a customer does not inadvertently lock himself out of the device during programming, it is recommended that he program the backdoor access key first, his application code second and the security bytes within the fm configuration field last. sys_clk (2) ) ( < < (div + 1) 150[khz] 200[khz] sys_clk (2)(8) ) ( < < (div + 1) 150[khz] 200[khz]

general characteristics 56f8322 technical data, rev. 10.0 freescale semiconductor 99 preliminary part 10 specifications 10.1 general characteristics the 56f8322/56f8122 are fabricated in high-density cmos with 5v-tolerant ttl-compatible digital inputs. the term 5v-tolerant refers to the capability of an i/o pin, built on a 3.3v-compatible process technology, to withstand a voltage up to 5.5v without damaging the device. many systems have a mixture of devices designed for 3.3v and 5v power supplies. in such systems, a bus may carry both 3.3v- and 5v-compatible i/o voltage levels (a standard 3.3v i/o is designed to receive a maximum voltage of 3.3v 10% during normal operation without causing damage). this 5v-tolerant capability therefore offers the power savings of 3.3v i/o levels combined with the ability to receive 5v levels without damage. absolute maximum ratings in table 10-1 are stress ratings only, and functional operation at the maximum is not guaranteed. stress beyond these ratings may affect device reliability or cause permanent damage to the device. note: all specifications meet both automotive and industrial requirements unless individual specifications are listed. note: the 56f8122 device is guaranteed to 40mhz and specified to meet industrial requirements only. caution this device contains protective circuitry to guard against damage due to high static voltage or electrical fields. however, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level.

56f8322 techncial data, rev. 10.0 132 freescale semiconductor preliminary part 12 design considerations 12.1 thermal design considerations an estimation of the chip junction temperature, t j , can be obtained from the equation: t j = t a + (r j x p d ) where: the junction to ambient thermal resistance is an industry-standard value that provides a quick and easy estimation of thermal performance. unfortunately, there are two values in common usage: the value determined on a single-layer board and the value obtained on a board with two planes. for packages such as the pbga, these values can be different by a factor of two. which value is closer to the application depends on the power dissipated by other components on the board. the value obtained on a single layer board is appropriate for the tightly packed printed circuit board. the value obtained on the board with the internal planes is usually appropriate if the board has low-power dissipation and the components are well separated. when a heat sink is used, the thermal resistance is expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: r ja = r jc + r ca where: r jc is device related and cannot be influenced by the user. the user controls the thermal environment to change the case-to-ambient thermal resistance, r ca . for instance, the user can change the size of the heat sink, the air flow around the device, the interface material, the mounting arrangement on printed circuit board, or change the thermal dissipation on the printed circuit board surrounding the device. to determine the junction temperature of the device in the application when heat sinks are not used, the thermal characterization parameter ( jt ) can be used to determine the junction temperature with a measurement of the temperature at the top center of the package case using the following equation: t j = t t + ( jt x p d ) where: t a = ambient temperature for the package ( o c) r j = junction to ambient thermal resistance ( o c/w) p d = power dissipation in the package (w) r ja = package junction to ambient thermal resistance c/w r jc = package junction to case thermal resistance c/w r ca = package case to ambient thermal resistance c/w t t = thermocouple temperature on top of package ( o c) jt = thermal characterization parameter ( o c)/w p d = power dissipation in package (w)
electrical design considerations 56f8322 technical data, rev. 10.0 freescale semiconductor 133 preliminary the thermal characterization parameter is measured per jesd51-2 specification using a 40-gauge type t thermocouple epoxied to the top center of the package case. the thermocouple should be positioned so that the thermocouple junction rests on the package. a small amount of epoxy is placed over the thermocouple junction and over about 1mm of wire extending from the junction. the thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. when heat sink is used, the junction temperature is determined from a thermocouple inserted at the interface between the case of the package and the interface material. a clearance slot or hole is normally required in the heat sink. minimizing the size of the clearance is important to minimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. because of the experimental difficulties with this technique, many engineers measure the heat sink temperature and then back-calculate the case temperature using a separate measurement of the thermal resistance of the interface. from this case temperature, the junction temperature is determined from the junction-to-case thermal resistance. 12.2 electrical design considerations use the following list of considerations to assure correct operation of the 56f8322/56f8122: ? provide a low-impedance path from the board power supply to each v dd pin on the device and from the board ground to each v ss (gnd) pin ? the minimum bypass requirement is to place six 0.01C0.1 f capacitors positioned as close as possible to the package supply pins. the recommended bypass configuration is to place one bypass capacitor on each of the v dd /v ss pairs, including v dda /v ssa. ceramic and tantalum capacitors tend to provide better tolerances. ? ensure that capacitor leads and associated printed circuit traces that connect to the chip v dd and v ss (gnd) pins are less than 0.5 inch per capacitor lead ? use at least a four-layer printed circuit board (pcb) with two inner layers for v dd and v ss ? bypass the v dd and v ss layers of the pcb with approximately 100 f, preferably with a high-grade capacitor such as a tantalum capacitor caution this device contains protective circuitry to guard against damage due to high static voltage or electrical fields. however, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level.
56f8322 techncial data, rev. 10.0 134 freescale semiconductor preliminary ? because the devices output signals have fast rise and fall times, pcb trace lengths should be minimal ? consider all device loads as well as parasitic capacitance due to pcb traces when calculating capacitance. this is especially critical in systems with higher capacitive loads that could create higher transient currents in the v dd and v ss circuits. ? take special care to minimize noise levels on the v ref , v dda and v ssa pins ? because the flash memory is programmed through the jtag/eonce port, the designer should provide an interface to this port to allow in-circuit flash programming 12.3 power distribution and i/o ring implementation figure 12-1 illustrates the general power control incorporated in the 56f8322/56f8122. this chip contains two internal power regulators. one of them is powered from the v dda_osc_pll pin and cannot be turned off. this regulator controls power to the internal clock generation circuitry. the other regulator is powered from the v dd_io pins and provides power to all of the internal digital logic of the core, all peripherals and the internal memories. this regulator can be turned off, if an external v dd_core voltage is externally applied to the v cap pins. in summary, the entire chip can be supplied from a single 3.3 volt supply if the large core regulator is enabled. if the regulator is not enabled, a dual supply 3.3v/2.5v configuration can also be used. notes: ? flash, ram and internal logic are powered from the core regulator output ?v pp 1 and v pp 2 are not connected in the customer system ? all circuitry, analog and digital, shares a common v ss bus figure 12-1 power management reg core v cap i/o adc v dd v ss ocs reg v dda_osc_pll rosc v ssa_adc v dda_adc v refh v refp v refmid v refn v reflo
