psoc ? 5lp: cy8c58lp family datasheet document number: 001-84932 rev. *c page 3 of 122 1. architectural overview introducing the cy8c58lp family of ultra lo w power, flash programmable system-on-chip (psoc) devices, part of a scalable 8-bit psoc 3 and 32-bit psoc 5lp platform. the cy8c 58lp family provides configurable blocks of analog, digital, and interconnect circu itry around a cpu subsystem. the combination of a cpu with a flexib le analog subsystem, digital subsystem, routing, and i/o enables a high level of integration in a wide variety of consumer, industrial, and medical applications. figure 1-1. simplified block diagram figure 1-1 illustrates the major components of the cy8c58lp family. they are: arm cortex-m3 cpu subsystem nonvolatile subsystem programming, debug, and test subsystem inputs and outputs clocking power digital subsystem analog subsystem psoc?s digital subsystem pr ovides half of its unique configurability. it connects a digital signal from any peripheral to any pin through the digital syst em interconnect (dsi). it also provides functional flexibility thr ough an array of small, fast, low power udbs. psoc creator provi des a library of pre-built and tested standard digital peripherals (uart, spi, lin, prs, crc, timer, counter, pwm, and, or, and so on) that are mapped to the udb array. you can also easily create a digital circuit using boolean primitives by means of graphical design entry. each udb contains programmable array logic (pal)/programmable logic device (pld) functionality, together with a small state machine engine to support a wide variety of peripherals. digital filter block lcd direct drive capsense temperature sensor 4 x opamp + - adcs 4 x dac 1 x del sig adc 4 x sc / ct blocks (tia, pga, mixer etc) 4 x cmp + - program debug & trace boundary scan program & debug cortex m3 cpu interrupt controller phub dma cache controller sram flash eeprom emif digital interconnect analog interconnect 1.71 to 5.5 v 0. 5 to 5.5 v ( optional ) 4- 25 mhz ( optional ) xtal osc 32.768 khz ( optional ) rtc timer imo clock tree wdt and wake ilo clocking system 1.8 v ldo smp por and lvd sleep power power management system usb phy 3 per opamp gpios gpios gpios gpios gpios gpios sio gpios sios 2 x sar adc i2c master/ slave universal digital block array (24 x udb) 4 x timer counter pwm fs usb 2.0 udb udb udb udb udb udb udb udb udb udb udb udb udb udb udb uart logic 12- bit pwm i2c slave 8- bit spi 12- bit spi logic 8- bit timer 16- bit prs udb 8- bit timer quadrature decoder 16- bit pwm sequencer usage example for udb udb udb udb udb udb udb udb udb 22 memory system cpu system analog system system bus digital system system wide resources can 2.0
psoc ? 5lp: cy8c58lp family datasheet document number: 001-84932 rev. *c page 4 of 122 in addition to the flexibility of the udb array, psoc also provides configurable digital blocks targeted at specific functions. for the cy8c58lp family, these blocks can include four 16-bit timers, counters, and pwm blocks; i 2 c slave, master, and multimaster; full-speed usb; and full can 2.0. for more details on the peripherals see the ?example peripherals? section on page 36 of this datasheet. for information on udbs, dsi, and other digital blocks, see the ?digital subsystem? section on page 36 of this datasheet. psoc?s analog subsystem is the second half of its unique configurability. all analog performance is based on a highly accurate absolute voltage reference with less than 0.1% error over temperature and voltage. the configurable analog subsystem includes: analog muxes comparators analog mixers voltage references adcs dacs digital filter block (dfb) all gpio pins can route analog signals into and out of the device using the internal analog bus. this allows the device to interface up to 62 discrete analog signals. one of the adcs in the analog subsystem is a fast, accurate, configurable delta-sigma adc with these features: less than 100-v offset a gain error of 0.2% integral non linearity (inl) less than 2 lsb differential non linearity (dnl) less than 1 lsb sinad better than 84 db in 16-bit mode this converter addresses a wide variety of precision analog applications including some of the most demanding sensors. the cy8c58lp family also offers up to two sar adcs. featuring 12-bit conversions at up to 1 m samples per second, they also offer low nonlinearity and offset errors and snr better than 70 db. they are well-suited for a variety of higher speed analog applications. the output of any of the adcs can optionally feed the programmable dfb via dma without cpu intervention. you can configure the dfb to perform iir and fir digital filters and several user defined custom f unctions. the dfb can implement filters with up to 64 taps. it can perform a 48-bit multiply-accumulate (mac) operation in one clock cycle. four high-speed voltage or current dacs support 8-bit output signals at an update rate of up to 8 msps. they can be routed out of any gpio pin. you can create higher resolution voltage pwm dac outputs using the udb array. this can be used to create a pulse width modulated (pwm) dac of up to 10 bits, at up to 48 khz. the digital dacs in each udb support pwm, prs, or delta-sigma algorithms with programmable widths. in addition to the adcs, dacs , and dfb, the analog subsystem provides multiple: comparators uncommitted opamps configurable switched capacitor/continuous time (sc/ct) blocks. these support: ? transimpedance amplifiers ? programmable gain amplifiers ? mixers ? other similar analog components see the ?analog subsystem? section on page 46 of this datasheet for more details. psoc?s cpu subsystem is built around a 32-bit three-stage pipelined arm cortex-m3 processor running at up to 67 mhz. the cortex-m3 includes a tigh tly integrated nested vectored interrupt controller (nvic) and various debug and trace modules. the overall cpu subsystem incl udes a dma controller, flash cache, and ram. the nvic pr ovides low latency, nested interrupts, and tail-chaining of interrupts and other features to increase the efficiency of interrupt handling. the dma controller enables peripherals to exchange data without cpu involvement. this allows the cpu to run slower (saving power) or use those cpu cycles to improve the perfo rmance of firmwa re algorithms. the flash cache also reduces system power consumption by allowing less frequent flash access. psoc?s nonvolatile subsystem cons ists of flash, byte-writeable eeprom, and nonvolatile configur ation options. it provides up to 256 kb of on-chip flash. the cpu can reprogram individual blocks of flash, enabling boot loaders. you can enable an ecc for high reliability applications. a po werful and flexible protection model secures the user's sensitive information, allowing selective memory block locking for read and write protection. two kb of byte-writable eeprom is available on-chip to store application data. additionally, selected configuration options such as boot speed and pin drive mode are stored in nonvolatile memory. this allows settings to activate immediately after por. the three types of psoc i/o are extremely flexible. all i/os have many drive modes that are set at por. psoc also provides up to four i/o voltage domains through the v ddio pins. every gpio has analog i/o, lcd drive, capsense, flexible interrupt generation, slew rate control, and digital i/o capability. the sios on psoc allow v oh to be set independently of v ddio when used as outputs. when sios are in input mode they are high impedance. this is true even when the device is not powered or when the pin voltage goes above the supply voltage. this makes the sio ideally suited for use on an i 2 c bus where the psoc may not be powered when other devices on the bus are. the sio pins also have high current sink capa bility for applications such as led drives. the programmable input threshold feature of the sio can be used to make the si o function as a general purpose analog comparator. for devices with fs usb, the usb physical interface is also provided (usbio). when not using usb, these pins may also be used for limited digital functionality and device programming. all the features of the psoc i/os are covered in detail in the ?i/o system and routing? section on page 29 of this datasheet.
psoc ? 5lp: cy8c58lp family datasheet document number: 001-84932 rev. *c page 5 of 122 the psoc device incorporates flexible internal clock generators, designed for high stability and factory trimmed for high accuracy. the internal main oscillator (imo ) is the master clock base for the system, and has one -percent accuracy at 3 mhz. the imo can be configured to run from 3 mhz up to 62 mhz. multiple clock derivatives can be generated from the main clock frequency to meet application needs. the device provides a pll to generate system clock frequencies up to 67 mhz from the imo, external crystal, or external reference clock. it also contains a separate, very low-power internal low-s peed oscillator (ilo) for the sleep and watchdog timers. a 32.768-khz external watch crystal is also supported for use in rtc applications. the clocks, together with programmable clock dividers, provide the flexibility to integrate most timing requirements. the cy8c58lp family supports a wide supply operating range from 1.71 to 5.5 v. this allows operation from regulated supplies such as 1.8 5%, 2.5 v 10%, 3.3 v 10%, or 5.0 v 10%, or directly from a wide range of battery types. in addition, it provides an integrated high efficiency synchronous boost converter that can power the device from supply voltages as low as 0.5 v. this enables the device to be powered directly from a single battery. in addition, you can use the boost converter to generate other voltages required by the device, such as a 3.3 v supply for lcd glass drive. the boost?s output is available on the vboost pin, allowing other devices in the application to be powered from the psoc. psoc supports a wide range of low power modes. these include a 300-na hibernate mode with ram retention and a 2-a sleep mode with rtc. in the second mode, the optional 32.768-khz watch crystal runs continuously and maintains an accurate rtc. power to all major functional blocks, including the programmable digital and analog peripherals, can be controlled independently by firmware. this allows low power background processing when some peripherals are not in use. this, in turn, provides a total device current of only 3.1 ma when the cpu is running at 6mhz. the details of the psoc power modes are covered in the ?power system? section on page 24 of this datasheet. psoc uses jtag (4 wire) or swd (2 wire) interfaces for programming, debug, and test. using these standard interfaces you can debug or program the psoc with a variety of hardware solutions from cypress or third party vendors. the cortex-m3 debug and trace modules include fpb, dwt, etm, and itm. these modules have many features to help solve difficult debug and trace problems. details of the programming, test, and debugging interfaces are discussed in the ?programming, debug interfaces, resources? section on page 57 of this datasheet. 2. pinouts each vddio pin powers a specific set of i/o pins.

they are not accessible by all 16-bit instructions. r13 r13 is the stack pointer register. it is a banked register that switches between two 32-bit stack pointers: the main stack pointer (msp) and the process stack pointer (psp). the psp is used only when the cpu operates at the user level in thread mode. the msp is used in all other privilege levels and modes. bits[0:1] of the sp are ignored and considered to be 0, so the sp is always aligned to a word (4 byte) boundary. r14 r14 is the link register (lr). the lr stores the return address when a subroutine is called. r15 r15 is the program counter (pc). bit 0 of the pc is ignored and considered to be 0, so instructions are always aligned to a half word (2 byte) boundary. xpsr the program status regi sters are divided into three status registers, which are accessed either together or separately: application program status register (apsr) holds program execution status bits such as zero, carry, negative, in bits[27:31]. interrupt program status register (ipsr) holds the current exception number in bits[0:8]. execution program status register (epsr) holds control bits for interrupt continuable and if-then instructions in bits[10:15] and [25:26]. bit 24 is always set to 1 to indicate thumb mode. trying to clear it causes a fault exception. primask a 1-bit interrupt mask register. when set, it allows only the nonmaskable interrupt (nmi) and hard fault exception. all other exceptions and interrupts are masked. faultmask a 1-bit interrupt mask register. when set, it allows only the nmi. all other exceptions and interrupts are masked. basepri a register of up to nine bits that define the masking priority level. when set, it disables all interrupts of the same or higher priority value. if set to 0 then the masking function is disabled. control a 2-bit register for controlling the operating mode. bit 0: 0 = privileged level in thread mode, 1 = user level in thread mode. bit 1: 0 = default stack (msp) is used, 1 = alternate stack is used. if in thread mode or user level then the alternate stack is the psp. there is no alternate stack for handler mode;

section on page 60). for more information on how to take full advantage of the security features in psoc, see the psoc 5 trm. disclaimer note the following details of th e flash code protection features on cypress devices. cypress products meet the spec ifications contained in their particular cypress datasheets. cypress believes that its family of products is one of the most secure families of its kind on the market today, regardless of how they are used. there may be methods, unknown to cypress, that can breach the code protection features. any of th ese methods, to our knowledge, would be dishonest and possibly illegal. neither cypress nor any other semiconductor manufacturer can guarantee the security of their code. code protection does not mean that we are guaranteeing the product as ?unbreakable.? cypress is willing to work with the customer who is concerned about the integrity of their code. code protection is constantly evolving. we at cypress are committed to continuously improving the code protecti on features of our products. 5.4 eeprom psoc eeprom memory is a byte addressable nonvolatile memory. the cy8c58lp has 2 kb of eeprom memory to store user data. reads from eeprom are random access at the byte level. reads are done directly; writes are done by sending write commands to an eeprom programming interface. cpu code execution can continue from fl ash during eeprom writes. eeprom is erasable and writea ble at the row level. the eeprom is divided into 128 rows of 16 bytes each. the cpu can not execute out of eeprom. there is no ecc hardware associated with eeprom. if ecc is required it must be handled in firmware. table 5-1. flash protection protection setting allowed not allowed unprotected external read and write + internal read and write ?

is set using the prt15.dm0[7, 6] register. a resistive pull option is also avail able at the usbio pins, which can be enabled using the prt15.dm1 [7, 6] register. when enabled for usb mode, the drive mode control has no impact on the configuration of the usb pins. unlike the g pio and sio configurations, the port wide configuration r egisters do not configure the usb drive mode bits. table 6-7 shows the drive mode configuration for the usbio pins. high impedance analog the default reset state with both the output driver and digital input buffer turned off. this prevents any current from flowing in the i/o?s digital input buffer due to a floating voltage. this state is recommended for pins that are floating or that support an analog voltage. high impedance analog pins do not provide digital input functionality. to achieve the lowest chip current in sleep modes, all i/os must either be configured to the high impedance analog mode, or have their pins driven to a power supply rail by the psoc device or by external circuitry. high impedance digital the input buffer is enabled for digital signal input. this is the standard high impedance (hiz) state recommended for digital inputs. resistive pull-up or resistive pull-down resistive pull-up or pull-down, respectively, provides a series resistance in one of the data states and strong drive in the other. pins can be used for di gital input and output in these modes. interfacing to mechani cal switches is a common application for these modes. resistive pull-up and pull-down are not available with sio in regulated output mode. open drain, drives high and open drain, drives low open drain modes provide high impedance in one of the data states and strong drive in the other. pins can be used for digital input and output in these modes. a common application for these modes is driving the i 2 c bus signal lines. strong drive provides a strong cmos output drive in either high or low state. this is the standard out put mode for pins. strong drive mode pins must not be used as inputs under normal circumstances. this mode is often used to drive digital output signals or external fets. resistive pull-up and pull-down similar to the resistive pull-u p and resistive pull-down modes except the pin is always in series with a resistor. the high data state is pull-up while the low da ta state is pull-down. this mode is most often used when othe r signals that may cause shorts can drive the bus. resistive pull-up and pull-down are not available with sio in regulated output mode. 6.4.2 pin registers registers to configure and interact with pins come in two forms that may be used interchangeably. all i/o registers are available in the standard port form, where each bit of the register corresp onds to one of the port pins. this register form is efficient for quickly reconfiguring multiple port pins at the same time. i/o registers are also available in pin form, which combines the eight most commonly used port register bits into a single register for each pin. this enables very fast configuration changes to individual pins with a single register write. 6.4.3 bidirectional mode high speed bidirectional capability allows pins to provide both the high impedance digital drive mode for input signals and a second user selected drive mode su ch as strong drive (set using prtxdm[2:0] registers) for output signals on the same pin, based on the state of an auxiliary control bus signal. the bidirectional capability is useful for processor busses and communications interfaces such as the spi slave miso pin that requires dynamic hardware control of the output buffer. the auxiliary control bus routes up to 16 udb or digital peripheral generated output enable signals to one or more pins. 6.4.4 slew rate limited mode gpio and sio pins have fast and slow output slew rate options for strong and open drain drive modes, not resistive drive modes. because it results in reduced emi, the slow edge rate option is recommended for signals that ar e not speed critical, generally less than 1 mhz. the fast slew rate is for signals between 1 mhz and 33 mhz. the slew rate is individually configurable for each pin, and is set by the prtxslw registers. 6.4.5 pin interrupts all gpio and sio pins are able to generate interrupts to the system. all eight pins in each port interface to their own port interrupt control unit (picu) and associated interrupt vector. each pin of the port is independent ly configurable to detect rising edge, falling edge, both edge interrupts, or to not generate an interrupt. table 6-7. usbio drive modes (p15[7] and p15[6]) prt15.dm1[7,6] pull up enable prt15.dm0[7,6] drive mode enable prt15.dr[7,6] = 1 prt15.dr[7,6] = 0 description 0 0 high z strong

psoc ? 5lp: cy8c58lp family datasheet document number: 001-84932 rev. *c page 35 of 122 the digital input path in figure 6-9 on page 31 illustrates this functionality. in the figure, ?reference level? is the analog signal routed through the analog global. the hysteresis feature can also be enabled for the input buffer of the sio, which increases noise immunity for the comparator. 6.4.14 hot swap this section applies only to sio pins. sio pins support ?hot swap? capability to plug into an application without loading the signals that are connected to the sio pins even when no power is applied to the psoc device. this allows the unpowered psoc to maintain a high impedance load to the external device while also preventing the psoc from being powered through a sio pin?s protection diode. powering the device up or down while connected to an operational i2c bus may cause transient states on the sio pins. the overall i2c bus design should take this into account. 6.4.15 overvoltage tolerance all i/o pins provide an overvoltage tolerance feature at any operating vdd. there are no current limitations for the sio pins as they present a high impedance load to the external circuit. the gpio pins must be limited to 100 a using a current limiting resistor. gpio pins clamp the pin voltage to approximately one diode above the vddio supply. in case of a gpio pin configured for analog input/output, the analog voltage on the pin must not exceed the vddio supply voltage to which the gpio belongs. a common application for this feature is connection to a bus such as i 2 c where different devices are running from different supply voltages. in the i 2 c case, the psoc chip is configured into the open drain, drives low mode fo r the sio pin. this allows an external pull-up to pull the i 2 c bus voltage above the psoc pin supply. for example, the psoc chip could operate at 1.8 v, and an external device could run from 5 v. note that the sio pin?s vih and vil levels are determi ned by the associated vddio supply pin. the sio pin must be in one of the following modes: 0 (high impedance analog), 1 (high impedance digital), or 4 (open drain drives low). see figure 6-11 for details. absolute maximum ratings for the device must be observed for all i/o pins. 6.4.16 reset configuration while reset is active all i/os are reset to and held in the high impedance analog state. after reset is released, the state can be reprogrammed on a port-by-port basis to pull-down or pull-up. to ensure correct reset operation, the port reset configuration data is stored in special nonvolatile registers. the stored reset data is automatically transferred to the port reset configuration registers at reset release. 6.4.17 low power functionality in all low power modes the i/o pins retain their state until the part is awakened and changed or reset. to awaken the part, use a pin interrupt, because the port interrupt logic continues to function in all low power modes. 6.4.18 special pin functionality some pins on the device include additional special functionality in addition to their gpio or sio functionality. the specific special function pins are listed in ?pinouts? on page 5. the special features are: digital ? 4- to 25-mhz crystal oscillator ? 32.768-khz crystal oscillator ? wake from sleep on i 2 c address match. any pin can be used for i 2 c if wake from sleep is not required. ? jtag interface pins ? swd interface pins ? swv interface pins ? traceport interface pins ? external reset analog ? opamp inputs and outputs ? high current idac outputs ? external reference inputs 6.4.19 jtag boundary scan the device supports standard jtag boundary scan chains on all pins for board level test.

psoc ? 5lp: cy8c58lp family datasheet document number: 001-84932 rev. *c page 40 of 122 7.2.2.3 conditionals each datapath has two compares, with bit masking options. compare operands include the two accumulators and the two data registers in a variety of configurations. other conditions include zero detect, all ones detect, and overflow. these conditions are the primary datapa th outputs, a selection of which can be driven out to the udb routing matrix. conditional computation can use the built in chaining to neighboring udbs to operate on wider data widths without the need to use routing resources. 7.2.2.4 variable msb the most significant bit of an ar ithmetic and shift function can be programmatically specified. this supports variable width crc and prs functions, and in conjunction with alu output masking, can implement arbitrary width timers, counters and shift blocks. 7.2.2.5 built-in crc/prs the datapath has built in support for single cycle cyclic redundancy check (crc) computation and pseudo random sequence (prs) generation of arbitrary width and arbitrary polynomial. crc/prs functions longer than 8 bits may be implemented in conjunction with pl d logic, or built in chaining may be use to extend the func tion into neighboring udbs. 7.2.2.6 input/output fifos each datapath contains two four-byte deep fifos, which can be independently configured as an input buffer (system bus writes to the fifo, datapath internal reads the fifo), or an output buffer (datapath internal writes to the fifo, the system bus reads from the fifo). the fifos genera te status that are selectable as datapath outputs and can ther efore be driven to the routing, to interact with sequencer s, interrupts, or dma. figure 7-5. example fifo configurations 7.2.2.7 chaining the datapath can be configured to chain conditions and signals such as carries and shift data with neighboring datapaths to create higher precision arithm etic, shift, crc/prs functions. 7.2.2.8 time multiplexing in applications that are over sa mpled, or do not need high clock rates, the single alu block in the datapath can be efficiently shared with two sets of register s and condition generators. carry and shift out data from the alu are registered and can be selected as inputs in subsequent cycles. this provides support for 16-bit functions in one (8-bit) datapath. 7.2.2.9 datapath i/o there are six inputs and six outputs that connect the datapath to the routing matrix. inputs fr om the routing provide the configuration for the datapath operation to perform in each cycle, and the serial data inputs. inputs can be routed from other udb blocks, other device peripherals, de vice i/o pins, and so on. the outputs to the routing can be selected from the generated conditions, and the serial data outputs. outputs can be routed to other udb blocks, device perip herals, interrupt and dma controller, i/o pins, and so on. 7.2.3 status and control module the primary purpose of this circuitry is to coordinate cpu firmware interaction with internal udb operation. figure 7-6. status and control registers the bits of the control register, which may be written to by the system bus, are used to drive in to the routing matrix, and thus provide firmware with the opportun ity to control the state of udb processing. the status register is read-only and it allows internal udb state to be read out onto the system bus directly from internal routing. this allows firmware to monitor the state of udb processing. each bit of these registers has programmable connections to the routing matrix and routing connections are made depending on the requirem ents of the application. 7.2.3.1 usage examples as an example of control input, a bit in the control register can be allocated as a function enable bit. there are multiple ways to enable a function. in one method the control bit output would be routed to the clock control block in one or more udbs and serve as a clock enable for the selected udb blocks. a status example is a case where a pld or datapath block generated a condition, such as a ?compare true? condit ion that is captured and latched by the status register and then read (and cleared) by cpu firmware. system bus f0 f1 system bus a0/a1/alu d0/d1 a0/a1/alu system bus f1 a0/a1/alu f0 d0 system bus f1 a0 d1 a1 f0 tx/rx dual capture dual buffer routing channel 8-bit status register (read only) 8-bit control register (write/read) system bus

debugging 9.5 swv and traceport interfaces the swv and traceport interfaces provide trace data to a debug host via the cypress miniprog3 or an external trace port analyzer. the 5 pin traceport is used for rapid transmission of large trace streams. the single pin swv mode is used to minimize the number of trace pins. swv is shared with a jtag pin. if debugging and tracing are done at the same time then swd may be used with either swv or traceport, or jtag may be used with traceport, as shown in table 9-1 . 9.6 programming features the jtag and swd interfaces provide full programming support. the entire device can be erased, programmed, and verified. designers can increase fl ash protection levels to protect firmware ip. flash protection can only be reset after a full device erase. individual flash blocks can be erased, programmed, and verified, if block security settings permit. 9.7 device security psoc 5lp offers an advanced security feature called device security, which permanently disables all test, programming, and debug ports, protecting your application from external access. the device security is activated by programming a 32-bit key (0x50536f43) to a write once latch (wol). the wol is a type of nonvolatile la tch (nvl). the cell itself is an nvl with additional logic wrapped around it. each wol device contains four bytes (32 bits) of data. the wrapper outputs a ?1? if a super-majority (28 of 32) of its bits match a pre-determined pattern (0x50536f43); it outputs a ?0? if this majority is not reached. when the output is 1, t he write once nv latch locks the part out of debug and test modes; it also permanently gates off the ability to erase or alter the contents of the latch. matching all bits is intentionally not required, so that single (or few) bit failures do not deassert the wol output. the state of the nvl bits after wafer processing is truly random with no tendency toward 1 or 0. the wol only locks the part af ter the correct 32-bit key (0x50536f43) is loaded into the nvl's volatile memory, programmed into the nvl's nonvolatile cells, and the part is reset. the output of the wol is only sampled on reset and used to disable the access. this precaution prevents anyone from reading, erasing, or altering the contents of the internal memory. the user can write the key into the wol to lock out external access only if no flash protection is set (see ?flash security? section on page 17). however, after setting the values in the wol, a user still has a ccess to the part until it is reset. therefore, a user can write the key into the wol, program the flash protection data, and then re set the part to lock it. if the device is protected with a wol setting, cypress cannot perform failure analysis and, t herefore, cannot accept rmas from customers. the wol can be read out via swd port to electrically identify protected part s. the user can write the key in wol to lock out external access only if no flash protection is set. for more information on how to take full advantage of the security features in psoc see the psoc 5 trm. disclaimer note the following details of th e flash code protection features on cypress devices. cypress products meet the spec ifications contained in their particular cypress datasheets. cypress believes that its family of products is one of the most secure families of its kind on the market today, regardless of how they are used. there may be methods, unknown to cypress, that can breach the code protection features. any of th ese methods, to our knowledge, would be dishonest and possibly illegal. neither cypress nor any other semiconductor manufacturer can guarantee the security of their code. code protection does not mean that we are guaranteeing the product as ?unbreakable.? cypress is willing to work with the customer who is concerned about the integrity of their code. code protection is constantly evolving. we at cypress are committed to continuously improving the code protecti on features of our products. table 9-1. debug configurations debug and trace configuration gpio pins used all debug and trace disabled 0 jtag 4 or 5 swd 2 swv 1 traceport 5 jtag + traceport 9 or 10 swd + swv 3 swd + traceport 7
