| Freescale Semiconductor, Inc. Advance Information MPC8240EC Rev. 4, 11/2003 MPC8240 Integrated Processor Hardware Specifications Freescale Semiconductor, Inc... The MPC8240 combines a MPC603e core microprocessor with a PCI bridge. The MPC8240 PCI support allows system designers to rapidly create systems using peripherals already designed for PCI and the other standard interfaces. The MPC8240 also integrates a high-performance memory controller that supports various types of DRAM and ROM. The MPC8240 is the first of a family of products that provide system-level support for industry standard interfaces with PowerPCTM microprocessor cores. This hardware specification describes pertinent electrical and physical characteristics of the MPC8240. For functional characteristics of the processor, refer to the MPC8240 Integrated Processor User's Manual (MPC8240UM). This hardware specification contains the following topics: Topic Section 1.1, "Overview" Section 1.2, "Features" Section 1.3, "General Parameters" Section 1.4, "Electrical and Thermal Characteristics" Section 1.5, "Package Description" Section 1.6, "PLL Configurations" Section 1.7, "System Design Information" Section 1.8, "Document Revision History" Section 1.9, "Ordering Information" Page 1 3 5 5 27 34 35 45 49 To locate any published errata or updates for this document, refer to the website at http://www.motorola.com/semiconductors. 1.1 Overview The MPC8240 integrated processor is comprised of a peripheral logic block and a 32-bit superscalar MPC603e core, as shown in Figure 1.

MPC8240 Block Diagram The peripheral logic integrates a PCI bridge, memory controller, DMA controller, PIC interrupt controller, I2O controller, and an I2C controller. The MPC603e core is a full-featured, high-performance processor with floating-point support, memory management, a 16-Kbyte instruction cache, a 16-Kbyte data cache, and 2 MPC8240 Integrated Processor Hardware Specifications MOTOROLA For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. Features power management features. The integration reduces the overall packaging requirements and the number of discrete devices required for an embedded system. The MPC8240 contains an internal peripheral logic bus that interfaces the MPC603e core to the peripheral logic. The core can operate at a variety of frequencies, allowing the designer to trade off performance for power consumption. The MPC603e core is clocked from a separate PLL, which is referenced to the peripheral logic PLL. This allows the microprocessor and the peripheral logic block to operate at different frequencies while maintaining a synchronous bus interface. The interface uses a 64- or 32-bit data bus (depending on memory data bus width) and a 32-bit address bus along with control signals that enable the interface between the processor and peripheral logic to be optimized for performance. PCI accesses to the MPC8240 memory space are passed to the processor bus for snooping purposes when snoop mode is enabled. The MPC8240 features serve a variety of embedded applications. In this way, the MPC603e core and peripheral logic remain general-purpose. The MPC8240 can be used as either a PCI host or an agent controller.

One DIMM is used for memory loading. 2. Maximum--FP power is measured at VDD = 2.5 V with dynamic power management enabled while running an entirely cache-resident, looping, floating-point multiplication instruction. 3. Maximum--INT power is measured at VDD = 2.5 V with dynamic power management enabled while running entirely cache-resident, looping, integer instructions. 4. Power saving mode maximums are measured at VDD = 2.5 V while the device is in doze, nap, or sleep mode. 5. Typical power is measured at VDD = AVDD = 2.5 V, OVDD = 3.3 V where a nominal FP value, a nominal INT value, and a value where there is a continuous flush of cache lines with alternating ones and zeros on 64-bit boundaries to local memory are averaged. 6. Power saving mode data measured with only two PCI_CLKs and two SDRAM_CLKs enabled. 7. The typical minimum I/O power values were results of the MPC8240 performing cache resident integer operations at the slowest frequency combination of 33:66:166 (PCI:Mem:CPU) MHz. 8. The typical maximum OVDD value resulted from the MPC8240 operating at the fastest frequency combination of 66:100:250 (PCI:Mem:CPU) MHz and performing continuous flushes of cache lines with alternating ones and zeros to PCI memory. 9. The typical maximum GVDD value resulted from the MPC8240 operating at the fastest frequency combination of 66:100:250 (PCI:Mem:CPU) MHz and performing continuous flushes of cache lines with alternating ones and zeros on 64-bit boundaries to local memory. 10.Power consumption on the PLL supply pins (AVDD and AVDD2) and the DLL supply pin (LAVDD) less than15 mW.

These specifications are for the default driver strengths indicated in Table 4. 2. Rise and fall times for the PCI_SYNC_IN input are measured from 0.4 to 2.4 V. 3. Specification value at maximum frequency of operation. 4. Relock time is guaranteed by design and characterization. Relock time is not tested. 5. Rise and fall times for the OSC_IN input are guaranteed by design and characterization. OSC_IN input rise and fall times are not tested. 6. Relock timing is guaranteed by design. PLL-relock time is the maximum amount of time required for PLL lock after a stable VDD and PCI_SYNC_IN are reached during the reset sequence. This specification also applies when the PLL has been disabled and subsequently re-enabled during sleep mode. Also note that HRST_CPU/HRST_CTRL must be held asserted for a minimum of 255 bus clocks after the PLL-relock time during the reset sequence. 7. DLL_STANDARD is bit 7 of the PMC2 register <72>. N is a non-zero integer (1 or 2). Tclk is the period of one SDRAM_SYNC_OUT clock cycle in ns. tloop is the propagation delay of the DLL synchronization feedback loop (PC board runner) from SDRAM_SYNC_OUT to SDRAM_SYNC_IN in ns; 6.25 inches of loop length (unloaded PC board runner) corresponds to approximately 1 ns of delay. tfix0 is a fixed delay inherent in the design when the DLL is at tap point 0 and the DLL is contributing no delay; tfix0 equals approximately 3 ns. See Figure 7 for DLL3 locking ranges. 8. Pin-to-pin skew includes quantifying the additional amount of clock skew (or jitter) from the DLL besides any intentional skew added to the clocking signals from the variable length DLL synchronization feedback loop, that is, the amount of variance between the internal sys_logic_clk and the SDRAM_SYNC_IN signal after the DLL is locked. While pin to pin skew between SDRAM_CLKs can be measured, the relationship between the internal sys_logic_clk and the external SDRAM_SYNC_IN cannot be measured and is guaranteed by design.

Notes: 1. All memory and related interface output signal specifications are specified from the VM = 1.4 V of the rising edge of the memory bus clock, SDRAM_SYNC_IN to the TTL level (0.8 or 2.0 V) of the signal in question. SDRAM_SYNC_IN is the same as PCI_SYNC_IN in 1:1 mode, but is twice the frequency in 2:1 mode (processor/memory bus clock rising edges occur on every rising and falling edge of PCI_SYNC_IN). See Figure 8. 2. All PCI signals are measured from OVDD/2 of the rising edge of PCI_SYNC_IN to 0.285 x OVDD or 0.615 x OVDD of the signal in question for 3.3-V PCI signaling levels. See Figure 9. 3. All output timings assume a purely resistive 50- load (see Figure 11). Output timings are measured at the pin; time-of-flight delays must be added for trace lengths, vias, and connectors in the system. 4. PCI bused signals are composed of the following signals: LOCK, IRDY, C/BE[0:3], PAR, TRDY, FRAME, STOP, DEVSEL, PERR, SERR, AD[0:31], REQ[4:0], GNT[4:0], IDSEL, and INTA. 5. PCI hold times can be varied; see Section 1.4.2.4.1, "PCI Signal Output Hold Timing," for information on programmable PCI output hold times. The values shown for item 13a are for PCI compliance. 6. These specifications are for the default driver strengths indicated in Table 4. Output Measurements are Made at the Device Pin Output Pin Z0 = 50 RL = 50 OVDD/2 for PCI GVDD/2 for Memory Figure 11. AC Test Load for the MPC8240 1.4.2.4.1 PCI Signal Output Hold Timing In order to meet minimum output hold specifications relative to PCI_SYNC_IN for both 33- and 66-MHz PCI systems, the MPC8240 has a programmable output hold delay for PCI signals. The initial value of the output hold delay is determined by the values on the MCP and CKE reset configuration signals. Further output hold delay values are available through programming the PCI_HOLD_DEL value of the PMCR2 configuration register. MOTOROLA MPC8240 Integrated Processor Hardware Specifications 17 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. Electrical and Thermal Characteristics Table 10 describes the bit values for the PCI_HOLD_DEL values in PMCR2. Table 10. Power Management Configuration Register 2 at 0x72 Bit Name Reset Value xx0 Description PCI output hold delay values relative to PCI_SYNC_IN. The initial values of bits 6 and 5 are determined by the reset configuration pins MCP and CKE, respectively. As these two pins have internal pull-up resistors, the default value after reset is 0b110. Although the minimum hold times are guaranteed at shown values, changes in the actual hold time can be made by incrementing or decrementing the value in these bit fields of this register through software or hardware configuration. The increment is in approximately 400-picosecond steps. Lowering the value in the 3-bit field decreases the amount of output hold available. 6-4 PCI_HOLD_DEL Freescale Semiconductor, Inc... 000 For Silicon Rev. 1.0/1.1: 66-MHz PCI.

Notes: 1. Units for these specifications are in SDRAM_CLK units. 2. The actual values depend on the setting of the digital filter frequency sampling rate (DFFSR) bits in the frequency divider register I2CFDR. Therefore, the noted timings in this table are all relative to qualified signals. The qualified SCL and SDA are delayed signals from what is seen in real time on the I2C bus. The qualified SCL and SDA signals are delayed by the SDRAM_CLK clock times DFFSR times two plus one SDRAM_CLK clock. The resulting delay value is added to the value in the table (where this note is referenced). See Figure 13. 3. Timing is relative to the sampling clock (not SCL). 4. FDR[x] refers to the frequency divider register I2CFDR bit n. 5. Input clock low and high periods in combination with the FDR value in the frequency divider register (I2CFDR) determine the maximum I2C input frequency. See Table 12.

PLL Configurations 1.6 PLL Configurations The MPC8240 internal PLLs are configured by the PLL_CFG[0:4] signals.

To ensure stability of the internal clocks, the power supplied to the AVDD, AVDD2, and LAVDD input signals should be filtered of any noise in the 500-KHz to 10-MHz resonant frequency range of the PLLs. Three separate circuits similar to the one shown in Figure 24 using surface mount capacitors with minimum effective series inductance (ESL) is recommended for AVDD, AVDD2, and LAVDD power signal pins. Consistent with the recommendations of Dr. Howard Johnson in High Speed Digital Design: A Handbook of Black Magic (Prentice Hall, 1993), using multiple small capacitors of equal value is recommended over using multiple values. The circuits should be placed as close as possible to the respective input signal pins to minimize noise coupled from nearby circuits. Routing directly as possible from the capacitors to the input signal pins with minimal inductance of vias is important.

The power consumption numbers provided in Table 5 do not reflect power from the OVDD and GVDD power supplies that are non-negligible for the MPC8240. In typical application measurements, the OVDD power ranged from 200 to 600 mW and the GVDD power ranged from 300 to 900 mW. The ranges' low-end power numbers were results of the MPC8240 performing cache-resident integer operations at the slowest frequency combination of 33:66:166 (PCI:Mem:CPU) MHz. The OVDD high-end range's value resulted from the MPC8240 performing continuous flushes of cache lines with alternating ones and zeros to PCI memory. The GVDD high-end range's value resulted from the MPC8240 operating at the fastest frequency combination of 66:100:250 (PCI:Mem:CPU) MHz and performing continuous flushes of cache lines with alternating ones and zeros on 64-bit boundaries to local memory. 1.7.3 Decoupling Recommendations Due to its dynamic power management feature, large address and data buses, and high operating frequencies, the MPC8240 can generate transient power surges and high frequency noise in its power supply, especially while driving large capacitive loads. This noise must be prevented from reaching other components in the MPC8240 system, and the MPC8240 itself requires a clean, tightly regulated source of power. Therefore, it is recommended that the system designer place at least one decoupling capacitor at each VDD, OVDD, GVDD, and LVDD pin of the MPC8240. It is also recommended that these decoupling capacitors receive their power from separate VDD, OVDD, GVDD, and GND power planes in the PCB, utilizing short traces to minimize inductance. These capacitors should have a value of 0.1 F. Only ceramic SMT (surface mount technology) capacitors should be used to minimize lead inductance, preferably 0508 or 0603, oriented such that connections are made along the length of the part. In addition, it is recommended that there be several bulk storage capacitors distributed around the PCB, feeding the VDD, OVDD, GVDD, and LVDD planes, to enable quick recharging of the smaller chip capacitors. These bulk capacitors should have a low ESR (equivalent series resistance) rating to ensure the quick response time necessary. They should also be connected to the power and ground planes through two vias to minimize inductance. Suggested bulk capacitors: 100-330 F (AVX TPS tantalum or Sanyo OSCON). 1.7.4 Connection Recommendations To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal level. Unused active low inputs should be tied to OVDD. Unused active high inputs should be connected to GND. All NC (no connect) signals must remain unconnected. Power and ground connections must be made to all external VDD, OVDD, GVDD, LVDD, and GND pins of the MPC8240. The PCI_SYNC_OUT signal is intended to be routed halfway out to the PCI devices and then returned to the PCI_SYNC_IN input of the MPC8240. 36 MPC8240 Integrated Processor Hardware Specifications MOTOROLA For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. System Design Information The SDRAM_SYNC_OUT signal is intended to be routed halfway out to the SDRAM devices and then returned to the SDRAM_SYNC_IN input of the MPC8240. The trace length may be used to skew or adjust the timing window as needed. See the Motorola application note AN1794, "Backside L2 Timing Analysis for PCB Design Engineers," for more information on this topic. 1.7.5 Pull-Up/Pull-Down Resistor Requirements The data bus input receivers are normally turned off when no read operation is in progress; therefore, they do not require pull-up resistors on the bus. The data bus signals are: DH[0:31], DL[0:31], and PAR[0:7]. If the 32-bit data bus mode is selected, the input receivers of the unused data and parity bits (DL[0:31] and PAR[4:7]) will be disabled, and their outputs will drive logic zeros when they would otherwise normally be driven. For this mode, these pins do not require pull-up resistors and should be left unconnected by the system to minimize possible output switching. Freescale Semiconductor, Inc... The TEST0 pins require pull-up resistors of 120 or less connected to OVDD. It is recommended that TEST2 have a weak pull-up resistor (2-10 k) connected to GVDD. It is recommended that the following signals be pulled up to OVDD with weak pull-up resistors (2-10 k): SDA, SCL, SMI, SRESET, TBEN, CHKSTOP_IN, and TEST1. It is recommended that the following PCI control signals be pulled up to LVDD with weak pull-up resistors (2-10 k): DEVSEL, FRAME, IRDY, LOCK, PERR, SERR, STOP, TRDY, and INTA. The resistor values may need to be adjusted stronger to reduce induced noise on specific board designs. The following pins have internal pull-up resistors enabled at all times: REQ[0:3], REQ4/DA4, TCK, TDI, TMS, and TRST. See Table 17 for more information. The following pins have internal pull-up resistors enabled only while the MPC8240 is in the reset state: GNT4/DA5, DL0, FOE, RCS0, SDRAS, SDCAS, CKE, AS, MCP, MAA[0:2], PMAA[0:2], and QACK/DA0. See Table 17 for more information. The following pins are reset configuration pins: GNT4/DA5, DL0, FOE, RCS0, CKE, AS, MCP, QACK/DA0, MAA[0:2], PMAA[0:2], and PLL_CFG[0:4]/DA[10:6]. These pins are sampled during reset to configure the device. Reset configuration pins should be tied to GND via 1-k pull-down resistors to ensure a logic 0 level is read into the configuration bits during reset if the default logic 1 level is not desired. Any other unused active-low input pins should be tied to a logic one level through weak pull-up resistors (2-10 k) to the appropriate power supply. Unused active-high input pins should be tied to GND through weak pull-down resistors (2-10 k). 1.7.6 JTAG Configuration Signals Boundary scan testing is enabled through the JTAG interface signals. The TRST signal is optional in the IEEE 1149.1 specification but is provided on all processors that implement the PowerPC architecture. While it is possible to force the TAP controller to the reset state using only the TCK and TMS signals, more reliable power-on reset performance will be obtained if the TRST signal is asserted during power-on reset. Because the JTAG interface is also used for accessing the common on-chip processor (COP) function, simply tying TRST to HRESET is not practical. The COP function of these processors allows a remote computer system (typically, a PC with dedicated hardware and debugging software) to access and control the internal operations of the processor. The COP MOTOROLA MPC8240 Integrated Processor Hardware Specifications 37 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. System Design Information interface connects primarily through the JTAG port of the processor, with some additional status monitoring signals. The COP port requires the ability to independently assert HRESET or TRST in order to fully control the processor. If the target system has independent reset sources, such as voltage monitors, watchdog timers, power supply failures, or push-button switches, the COP reset signals must be merged into these signals with logic. The arrangement shown in Figure 25 allows the COP to independently assert HRESET or TRST, while ensuring that the target can drive HRESET as well. If the JTAG interface and COP header will not be used, TRST should be tied to HRESET so that it is asserted when the system reset signal (HRESET) is asserted ensuring that the JTAG scan chain is initialized during power-on. The COP header shown in Figure 25 adds many benefits--breakpoints, watchpoints, register and memory examination/modification, and other standard debugger features are possible through this interface--and can be as inexpensive as an unpopulated footprint for a header to be added when needed. Freescale Semiconductor, Inc... The COP interface has a standard header for connection to the target system, based on the 0.025" square-post, 0.100" centered header assembly (often called a Berg header). There is no standardized way to number the COP header shown in Figure 25; consequently, many different pin numbers have been observed from emulator vendors. Some are numbered top-to-bottom then left-to-right, while others use left-to-right then top-to-bottom, while still others number the pins counter clockwise from pin 1 (as with an IC). Regardless of the numbering, the signal placement recommended in Figure 25 is common to all known emulators. 38 MPC8240 Integrated Processor Hardware Specifications MOTOROLA For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc.

The MPC8240 only tolerates 5-V signals when interfaced into a 5-V PCI bus system. 1.7.8 Thermal Management Information This section provides thermal management information for the tape ball grid array (TBGA) package for air-cooled applications. Proper thermal control design is primarily dependent on the system-level design--the heat sink, airflow, and thermal interface material. To reduce the die-junction temperature, heat sinks may be attached to the package by several methods: adhesive, spring clip to holes in the printed-circuit board, or package and mounting clip and screw assembly.

Figure 28. TBGA Package with Heat Sink Mounted to a Printed-Circuit Board For this cavity-down, wire-bond TBGA package, heat generated on the active side of the chip is conducted through the silicon, die attach, and package spreader, through the heat sink attach material (or thermal interface material), and finally to the heat sink, where it is removed by forced-air convection. 1.7.8.2 Adhesives and Thermal Interface Materials A thermal interface material is recommended at the package lid-to-heat sink interface to minimize thermal contact resistance. For those applications where the heat sink is attached by a spring clip mechanism, Figure 29 shows the thermal performance of three thin-sheet thermal-interface materials (silicone, 42 MPC8240 Integrated Processor Hardware Specifications MOTOROLA For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. System Design Information graphite/oil, floroether oil), a bare joint, and a joint with thermal grease as a function of contact pressure. As shown, the performance of these thermal interface materials improves with increased contact pressure. The use of thermal grease significantly reduces the interface thermal resistance, that is, the bare joint results in a thermal resistance approximately seven times greater than that of the thermal grease joint. Heat sinks are attached to the package by means of a spring clip to holes in the printed-circuit board (see Figure 26). Therefore, the synthetic grease offers the best thermal performance, considering the low interface pressure. Of course, the selection of any thermal interface material depends on many factors: thermal performance requirements, manufacturability, service temperature, dielectric properties, cost, and so on. 2 Silicone Sheet (0.006 in.)

For preliminary heat sink sizing, the die-junction temperature, TJ, can be expressed as follows: TJ = TA + TR + (RJC + RINT + RSA) x PD where TJ is the die-junction temperature TA is the inlet cabinet ambient temperature TR is the air temperature rise within the computer cabinet RJC is the junction-to-case thermal resistance RINT is the adhesive or interface material thermal resistance RSA is the heat sink base-to-ambient thermal resistance PD is the power dissipated by the device During operation, the die-junction temperatures (TJ) should be maintained at less than the value specified in Table 2. The temperature of the air cooling the component greatly depends on the ambient inlet air temperature and the air temperature rise within the electronic cabinet. An electronic cabinet inlet-air temperature (TA) may range from 30 to 40C. The air temperature rise within a cabinet (TR) may be in the range of 5 to 10C. The thermal resistance of the thermal interface material (RINT) is typically about 1C/W. Assuming a TA of 30C, a TR of 5C, a TBGA package RJC = 1.8, and a power consumption (PD) of 5.0 watts, the following expression for TJ is obtained for die-junction temperature: TJ = 30C + 5C + (1.8C/W + 1.0C/W + RSA) x 5.0 W For preliminary heat sink sizing, the heat sink base-to-ambient thermal resistance is needed from the heat sink manufacturer. Though the die junction-to-ambient and the heat sink-to-ambient thermal resistances are a common figure of merit used for comparing the thermal performance of various microelectronic packaging technologies, one should exercise caution when using only this metric in determining thermal management because no single parameter can adequately describe three-dimensional heat flow. The final die-junction operating temperature is not only a function of the component-level thermal resistance, but the system-level design and its operating conditions. In addition to the component's power consumption, a number of factors affect the final operating die-junction temperature: airflow, board population (local heat flux of adjacent components), heat sink efficiency, heat sink attach, heat sink placement, next-level interconnect technology, system air temperature rise, altitude, and so on. Due to the complexity and the many variations of system-level boundary conditions for today's microelectronic equipment, the combined effects of the heat transfer mechanisms (radiation, convection, 44 MPC8240 Integrated Processor Hardware Specifications MOTOROLA For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. Document Revision History and conduction) may vary widely. For these reasons, it is recommended that conjugate heat-transfer models for the board, as well as system-level designs, be used. 1.8 Document Revision History Table 19.
