MPC8536E Pinout Listing (continued) Signal Signal Name Package Pin Number Pin Type Power Supply Notes Notes: 1. All multiplexed signals may be listed only once and may not re-occur. 2. Recommend a weak pull-up resistor (2–10 KΩ) be placed on this pin to OVDD. 3. This pin must always be pulled-high. 4. This pin is an open drain signal. 5. This pin is a reset configuration pin. It has a weak internal pull-up P-FET which is enabled only when the processor is in the reset state. This pull-up is designed such that it can be overpowered by an external 4.7-kΩ pull-down resistor. However, if the signal is intended to be high after reset, and if there is any device on the net which might pull down the value of the net at reset, then a pullup or active driver is needed. 6. Treat these pins as no connects (NC) unless using debug address functionality. 7. The value of LA[28:31] during reset sets the CCB clock to SYSCLK PLL ratio. These pins require 4.7-kΩ pull-up or pull-down resistors. See Section 22.2, “CCB/SYSCLK PLL Ratio.” 8. The value of LALE, LGPL2 and LBCTL at reset set the e500 core clock to CCB Clock PLL ratio. These pins require 4.7-kΩ pull-up or pull-down resistors. See the Section 22.3, “e500 Core PLL Ratio.” 9. Functionally, this pin is an output, but structurally it is an I/O because it either samples configuration input during reset or because it has other manufacturing test functions. This pin will therefore be described as an I/O for boundary scan. 10. For proper state of these signals during reset, these pins can be left without any pulldowns, thus relying on the internal pullup to get the values to the require 2'b11.However, if there is any device on the net which might pull down the value of the net at reset, then a pullup is needed. 11. This output is actively driven during reset rather than being three-stated during reset. 12. These JTAG pins have weak internal pull-up P-FETs that are always enabled. 13. These pins are connected to the VDD_CORE/V DD_PLAT/GND planes internally and may be used by the core power supply to improve tracking and regulation. 15. These pins have other manufacturing or debug test functions. It is recommended to add both pull-up resistor pads to OVDD and pull-down resistor pads to GND on board to support future debug testing when needed. 16. If this pin is connected to a device that pulls down during reset, an external pull-up is required to drive this pin to a safe state during reset. 17. This pin is only an output in FIFO mode when used as Rx Flow Control. 18. Do not connect. 19.These must be pulled up (100 Ω- 1 kΩ) to OVDD. 20. Independent supplies derived from board VDD. 21. Recommend a pull-up resistor (1 KΩ) be placed on this pin to OV DD. 22. The following pins must NOT be pulled down during power-on reset: MDVAL, UART_SOUT[0:1], EC_MDC, TSEC1_TXD[3], TSEC3_TXD[7], HRESET_REQ, TRIG_OUT/READY/QUIESCE, MSRCID[2:4], ASLEEP. 23. This pin requires an external 4.7-kΩ pull-down resistor to prevent PHY from seeing a valid Transmit Enable before it is actively driven. 24. General-Purpose POR configuration of user system.

MPC8536E Pinout Listing (continued) Signal Signal Name Package Pin Number Pin Type Power Supply Notes 25. When a PCI block is disabled, either the POR config pin that selects between internal and external arbiter must be pulled down to select external arbiter if there is any other PCI device connected on the PCI bus, or leave the address pins as “No Connect” or terminated through 2–10 KΩ pull-up resistors with the default of internal arbiter if the address pins are not connected to any other PCI device. The PCI block will drive the address pins if it is configured to be the PCI arbiter—through POR config pins—irrespective of whether it is disabled via the DEVDISR register or not. It may cause contention if there is any other PCI device connected on the bus. 26. MDIC[0] is grounded through an 18.2-Ω (full-strength mode) or 36.4-Ω (half-strength mode) precision 1% resistor and MDIC[1] is connected to GVDD through an 18.2-Ω (full-strength mode) or 36.4-Ω (half-strength mode) precision 1% resistor. These pins are used for automatic calibration of the DDR IOs. 27. Connect to GND through a pull down 1 kΩ resistor 28. It must be the same as VDD_CORE 29. The output pads are tristated and the receivers of pad inputs are disabled during the Deep Sleep state when GCR[DEEPSLEEP_Z] =1. 30. DDRCLK input is only required when the DDR controller is running in asynchronous mode. When the DDR controller is configured to run in synchronous mode via POR setting cfg_ddr_pll[0:2]=111, the DDRCLK input is not required. It is recommended to tie it off to GND when DDR controller is running in synchronous mode. See the MPC8536E PowerQUICC™ III Integrated Host Processor Family Reference Manual, Rev.0, Table 4-3 in section 4.2.2 “Clock Signals”, section 4.4.3.2 “DDR PLL Ratio” and Table 4-10 “DDR Complex Clock PLL Ratio” for more detailed description regarding DDR controller operation in asynchronous and synchronous modes. 31. EC_GTX_CLK125 is a 125-MHz input clock shared among all eTSEC ports in the following modes: GMII, TBI, RGMII and RTBI. If none of the eTSEC ports is operating in these modes, the EC_GTX_CLK125 input can be tied off to GND. 32. SDHC_WP is active low signal, which follows SDHC Host controller specification. However, it is reversed polarity for SD/MMC card specification. 2 Electrical Characteristics 2.1 Overall DC Electrical Characteristics This section covers the ratings, conditions, and other characteristics. 2.1.1 Absolute Maximum Ratings Table 2 provides the absolute maximum ratings.

For DDR, tCLOCK references MCLK. For eTSEC, tCLOCK references EC_GTX_CLK125. For eLBC, tCLOCK references LCLK. For PCI, tCLOCK references PCI1_CLK or SYSCLK. 2. With the PCI overshoot allowed (as specified above), the device does not fully comply with the maximum AC ratings and device protection guideline outlined in the PCI rev. 2.2 standard (section 4.2.2.3). Figure 7. Overshoot/Undershoot Voltage for GVDD/OVDD/LVDD The core voltage must always be provided at nominal 1.0 Vor 1.1 V (See Table 2 for actual recommended core voltage). Voltage to the processor interface I/Os are provided through separate sets of supply pins and must be provided at the voltages shown in Table 2. The input voltage threshold scales with respect to the associated I/O supply voltage. OV DD and LVDD based receivers are simple CMOS I/O circuits and satisfy appropriate LVCMOS type specifications. The DDR2 and DDR3 SDRAM interface uses differential receivers referenced by the externally supplied MV REFn signal (nominally set to GVDD/2) as is appropriate for the SSTL_1.8 electrical signaling standard for DDR2 or 1.5-V electrical signaling for DDR3. The DDR DQS receivers cannot be operated in single-ended fashion. The complement signal must be properly driven and cannot be grounded.

The drive strength of the local bus interface is determined by the configuration of the appropriate bits in PORIMPSCR. 2. The drive strength of the PCI interface is determined by the setting of the PCI1_GNT1 signal at reset. 3. The drive strength of the DDR2 or DDR3 interface in half-strength mode is at Tj = 105°C and at GVDD (min) 2.2 Power Sequencing The MPC8536E requires its power rails to be applied in a specific sequence in order to ensure proper device operation. These requirements are as follows for power up: 1. 2. 3. VDD_PLAT, VDD_CORE (if POWER_EN is not used to control VDD_CORE), AVDD, BVDD, LVDD, OVDD, SVDD,S2V DD, TVDD, XVDD and X2VDD [Wait for POWER_EN to assert], then VDD_CORE (if POWER_EN is used to control VDD_CORE) GVDD All supplies must be at their stable values within 50 ms. Items on the same line have no ordering requirement with respect to one another. Items on separate lines must be ordered sequentially such that voltage rails on a previous step must reach 90% of their value before the voltage rails on the current step reach 10% of theirs. In order to guarantee MCKE low during power-up, the above sequencing for GVDD is required. If there is no concern about any of the DDR signals being in an indeterminate state during power-up, then the sequencing for GVDD is not required. From a system standpoint, if any of the I/O power supplies ramp prior to the VDD platform supply, the I/Os associated with that I/O supply may drive a logic one or zero during power-up, and extra current may be drawn by the device. During the Deep Sleep state, the VDD core supply is removed. But all other power supplies remain applied. Therefore, there is no requirement to apply the VDD core supply before any other power rails when the silicon waking from Deep Sleep.

Caution: The CCB clock to SYSCLK ratio and e500 core to CCB clock ratio settings must be chosen such that the resulting SYSCLK frequency, e500 (core) frequency, and CCB clock frequency do not exceed their respective maximum or minimum operating frequencies. See Section 2.23.2, “CCB/SYSCLK PLL Ratio,” and Section 2.23.3, “e500 Core PLL Ratio,” for ratio settings. 2. Rise and fall times for SYSCLK are measured at 0.6 V and 2.7 V. 3. The SYSCLK driver’s closed loop jitter bandwidth should be <500 kHz at -20 dB. The bandwidth must be set low to allow cascade-connected PLL-based devices to track SYSCLK drivers with the specified jitter. 4. For spread spectrum clocking, guidelines are +0% to -1% down spread at a modulation rate between 20 KHz and 60 KHz on SYSCLK. 2.4.2 PCI Clock Timing When the PCI controller is configured for asynchronous operation, the reference clock for the PCI controller is not the SYSCLK input, but instead the PCI_CLK.

The output of the sampling latch is then used as an input to the counters of the PIC and the TimeBase unit of the e500. There is no jitter specification. The minimum pulse width of the RTC signal should be greater than 2x the period of the CCB clock. That is, minimum clock high time is 2 × tCCB, and minimum clock low time is 2 × tCCB. There is no minimum RTC frequency; RTC may be grounded if not needed.

For example, tDDKHAS symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes from the high (H) state until outputs (A) are setup (S) or output valid time. Also, tDDKLDX symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes low (L) until data outputs (D) are invalid (X) or data output hold time. 2. All MCK/MCK referenced measurements are made from the crossing of the two signals ±0.1 V. 3. ADDR/CMD includes all DDR SDRAM output signals except MCK/MCK, MCS, and MDQ/MECC/MDM/MDQS. 4. Note that tDDKHMH follows the symbol conventions described in note 1. For example, tDDKHMH describes the DDR timing (DD) from the rising edge of the MCK[n] clock (KH) until the MDQS signal is valid (MH). tDDKHMH can be modified through control of the DQSS override bits in the TIMING_CFG_2 register. This will typically be set to the same delay as the clock adjust in the CLK_CNTL register. The timing parameters listed in the table assume that these 2 parameters have been set to the same adjustment value. See the MPC8536E PowerQUICC™ III Integrated Processor Reference Manual for a description and understanding of the timing modifications enabled by use of these bits. 5. Determined by maximum possible skew between a data strobe (MDQS) and any corresponding bit of data (MDQ), ECC (MECC), or data mask (MDM). The data strobe should be centered inside of the data eye at the pins of the microprocessor. 6. All outputs are referenced to the rising edge of MCK[n] at the pins of the microprocessor. Note that tDDKHMP follows the symbol conventions described in note 1. 7. Maximum DDR2 and DDR3 frequency is 667 MHz NOTE For the ADDR/CMD setup and hold specifications in Table 19, it is assumed that the Clock Control register is set to adjust the memory clocks by 1/2 applied cycle.

The RGMII and RTBI interfaces follow the Reduced Gigabit Media-Independent Interface (RGMII) Specification Version 1.3 (12/10/2000). The RMII interface follows the RMII Consortium RMII Specification Version 1.2 (3/20/1998).

However, the FIFO interface provides deliberate skew between the transmitted data and source clock in GMII fashion. When the eTSEC is configured for FIFO modes, all clocks are supplied from external sources to the relevant eTSEC interface. That is, the transmit clock must be applied to the eTSECn’s TSECn_TX_CLK, while the receive clock must be applied to pin TSECn_RX_CLK. The eTSEC internally uses the transmit clock to synchronously generate transmit data and outputs an echoed copy of the transmit clock back out onto the TSECn_GTX_CLK pin (while transmit data appears on TSECn_TXD[7:0], for example). It is intended that external receivers capture eTSEC transmit data using the clock on TSECn_GTX_CLK as a sourcesynchronous timing reference. Typically, the clock edge that launched the data can be used, since the clock is delayed by the eTSEC to allow acceptable set-up margin at the receiver. Note that there is relationship between the maximum FIFO speed and the platform speed. For more information see Section 2.4.6, “Platform to FIFO Restrictions.” A summary of the FIFO AC specifications appears in Table 26 and Table 27. Table 26.

Note that, in general, the clock reference symbol representation for this section is based on the symbols RGT to represent RGMII and RTBI timing. For example, the subscript of tRGT represents the TBI (T) receive (RX) clock. Note also that the notation for rise (R) and fall (F) times follows the clock symbol that is being represented. For symbols representing skews, the subscript is skew (SK) followed by the clock that is being skewed (RGT). 2. This implies that PC board design will require clocks to be routed such that an additional trace delay of greater than 1.5 ns will be added to the associated clock signal. 3. For 10 and 100 Mbps, tRGT scales to 400 ns ± 40 ns and 40 ns ± 4 ns, respectively. 4. Duty cycle may be stretched/shrunk during speed changes or while transition to a received packet's clock domains as long as the minimum duty cycle is not violated and stretching occurs for no more than three tRGT of the lowest speed transitioned between.

For example, tMTKHDX symbolizes MII transmit timing (MT) for the time tMTX clock reference (K) going high (H) until data outputs (D) are invalid (X). Note that, in general, the clock reference symbol representation is based on two to three letters representing the clock of a particular functional. For example, the subscript of tMTX represents the MII(M) transmit (TX) clock. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall).

Each output pin of the SerDes transmitter differential pair features 50-Ω output impedance. Each input of the SerDes receiver differential pair features 50-Ω on-die termination to S2GND (xcorevss). The reference circuit of the SerDes transmitter and receiver is shown in Figure 68. When an eTSEC port is configured to operate in SGMII mode, the parallel interface’s output signals of this eTSEC port can be left floating. The input signals should be terminated based on the guidelines described in Section 3.6, “Connection Recommendations,” as long as such termination does not violate the desired POR configuration requirement on these pins, if applicable. MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 54 Freescale Semiconductor Ethernet: Enhanced Three-Speed Ethernet (eTSEC), MII Management When operating in SGMII mode, the eTSEC EC_GTX_CLK125 clock is not required for this port. Instead, SerDes reference clock is required on SD2_REF_CLK and SD2_REF_CLK pins. 2.9.3.1 DC Requirements for SGMII SD2_REF_CLK and SD2_REF_CLK The characteristics and DC requirements of the separate SerDes reference clock are described in Section 2.20, “High-Speed Serial Interfaces.” 2.9.3.2 AC Requirements for SGMII SD2_REF_CLK and SD2_REF_CLK Table 38 lists the SGMII SerDes reference clock AC requirements.

When TMR_CTRL[CKSEL]=00, the external TSEC_1588_CLK input is selected as the 1588 timer reference clock source, with the timing defined in the Table above. The maximum value of tT1588CLK is defined in terms of TTX_CLK, which is the maximum clock cycle period of the equivalent interface speed that the eTSEC1 port is running. When eTSEC1 is configured to operate in the parallel mode, the TTX_CLK is the maximum clock period of the TSEC1_TX_CLK. When eTSEC1 operates in SGMII mode, the maximum value of tT1588CLK is defined in terms of the recovered clock from SGMII SerDes. For example, for 10/100/1000 Mbps modes, the maximum value of tT1588CLK will be 2800, 280, and 56 ns respectively. See the MPC8536E PowerQUICC™ III Integrated Communications Processor Reference Manual for a description of TMR_CTRL registers. 2.

The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tMDKHDX symbolizes management data timing (MD) for the time tMDC from clock reference (K) high (H) until data outputs (D) are invalid (X) or data hold time. Also, tMDDVKH symbolizes management data timing (MD) with respect to the time data input signals (D) reach the valid state (V) relative to the tMDC clock reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall). 2. This parameter is dependent on the eTSEC system clock speed, which is half of the Platform Frequency (fCCB). The actual EC_MDC output clock frequency for a specific eTSEC port can be programmed by configuring the MgmtClk bit field of MPC8536E’s MIIMCFG register, based on the platform (CCB) clock running for the device. The formula is: Platform Frequency (CCB)/(2*Frequency Divider determined by MIICFG[MgmtClk] encoding selection). For example, if MIICFG[MgmtClk] = 000 and the platform (CCB) is currently running at 533 MHz, fMDC = 533/(2*4*8) = 533/64 = 8.3 MHz. That is, for a system running at a particular platform frequency (fCCB), the EC_MDC output clock frequency can be programmed between maximum fMDC = fCCB/64 and minimum fMDC = fCCB/448. See the MPC8536E reference manual’s MIIMCFG register section for more detail. 3. This parameter is dependent on the platform clock frequency. The delay is equal to 16 platform clock periods +/-3ns. For example, with a platform clock of 333MHz, the min/max delay is 48ns +/-3ns. Similarly, if the platform clock is 400MHz, the min/max delay is 40ns +/-3ns). 5. tCLKplb_clk is the platform (CCB) clock 6.

The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tI2DVKH symbolizes I2C timing (I2) with respect to the time data input signals (D) reach the valid state (V) relative to the tI2C clock reference (K) going to the high (H) state or setup time. Also, tI2SXKL symbolizes I2C timing (I2) for the time that the data with respect to the start condition (S) went invalid (X) relative to the tI2C clock reference (K) going to the low (L) state or hold time. Also, tI2PVKH symbolizes I2C timing (I2) for the time that the data with respect to the stop condition (P) reaching the valid state (V) relative to the tI2C clock reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall). 2. As a transmitter, the MPC8536E provides a delay time of at least 300 ns for the SDA signal (referred to the Vihmin of the SCL signal) to bridge the undefined region of the falling edge of SCL to avoid unintended generation of Start or Stop condition. When the MPC8536E acts as the I2C bus master while transmitting, the MPC8536E drives both SCL and SDA. As long as the load on SCL and SDA are balanced, the MPC8536E would not cause unintended generation of Start or Stop condition. Therefore, the 300 ns SDA output delay time is not a concern. If, under some rare condition, the 300 ns SDA output delay time is required for the MPC8536E as transmitter, the following setting is recommended for the FDR bit field of the I2CFDR register to ensure both the desired I2C SCL clock frequency and SDA output delay time are achieved, assuming that the desired I2C SCL clock frequency is 400 KHz and the Digital Filter Sampling Rate Register (I2CDFSRR) is programmed with its default setting of 0x10 (decimal 16): I2C Source Clock Frequency 333 MHz 266 MHz 200 MHz 133 MHz FDR Bit Setting 0x2A 0x05 0x26 0x00 Actual FDR Divider Selected 896 704 512 384 378 KHz 390 KHz 346 KHz Actual I2C SCL Frequency Generated 371 KHz 2C frequency calculation, refer to Determining the I2C Frequency Divider Ratio for SCL (AN2919). Note that For details of the I the I2C Source Clock Frequency is half of the CCB clock frequency for the MPC8536E. 3. The maximum tI2DVKH has only to be met if the device does not stretch the LOW period (tI2CL) of the SCL signal. 4. CB = capacitance of one bus line in pF.

Also, tPCRHFV symbolizes PCI timing (PC) with respect to the time hard reset (R) went high (H) relative to the frame signal (F) going to the valid (V) state. 2.

PCI Output AC Timing Measurement Condition 2.20 High-Speed Serial Interfaces The MPC8536E features two Serializer/Deserializer (SerDes) interfaces to be used for high-speed serial interconnect applications. The SerDes1 interface is dedicated for PCI Express data transfers. The SerDes2 can be used for SGMII or SATA. This section describes the common portion of SerDes DC electrical specifications, which is the DC requirement for SerDes Reference Clocks. The SerDes data lane’s transmitter and receiver reference circuits are also shown. 2.20.1 Signal Terms Definition The SerDes utilizes differential signaling to transfer data across the serial link. This section defines terms used in the description and specification of differential signals. Figure 57 shows how the signals are defined. For illustration purposes, only one SerDes lane is used for description. The figure shows waveform for either a transmitter output (SDn_TX and SDn_TX) or a receiver input (SDn_RX and SDn_RX). Each signal swings between A Volts and B Volts where A > B. Using this waveform, the definitions are as follows. To simplify illustration, the following definitions assume that the SerDes transmitter and receiver operate in a fully symmetrical differential signaling environment. 1. Single-Ended Swing The transmitter output signals and the receiver input signals SDn_TX, SDn_TX, SDn_RX and SDn_RX each have a peak-to-peak swing of A - B Volts. This is also referred as each signal wire’s Single-Ended Swing. 2. Differential Output Voltage, VOD (or Differential Output Swing): The Differential Output Voltage (or Swing) of the transmitter, V OD, is defined as the difference of the two complimentary output voltages: VSDn_TX - VSDn_TX. The VOD value can be either positive or negative. 3. Differential Input Voltage, VID (or Differential Input Swing): MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 91 High-Speed Serial Interfaces The Differential Input Voltage (or Swing) of the receiver, V ID, is defined as the difference of the two complimentary input voltages: VSDn_RX - V SDn_RX. The VID value can be either positive or negative. 4. Differential Peak Voltage, VDIFFp The peak value of the differential transmitter output signal or the differential receiver input signal is defined as Differential Peak Voltage, VDIFFp = |A - B| Volts. 5. Differential Peak-to-Peak, VDIFFp-p Since the differential output signal of the transmitter and the differential input signal of the receiver each range from A - B to -(A - B) Volts, the peak-to-peak value of the differential transmitter output signal or the differential receiver input signal is defined as Differential Peak-to-Peak Voltage, VDIFFp-p = 2*VDIFFp = 2 * |(A - B)| Volts, which is twice of differential swing in amplitude, or twice of the differential peak. For example, the output differential peak-peak voltage can also be calculated as V TX-DIFFp-p = 2*|VOD|. 6. Common Mode Voltage, Vcm The Common Mode Voltage is equal to one half of the sum of the voltages between each conductor of a balanced interchange circuit and ground. In this example, for SerDes output, Vcm_out = VSDn_TX + VSDn_TX = (A + B) / 2, which is the arithmetic mean of the two complimentary output voltages within a differential pair. In a system, the common mode voltage may often differ from one component’s output to the other’s input. Sometimes, it may be even different between the receiver input and driver output circuits within the same component. It is also referred as the DC offset in some occasion. SDn_TX or SDn_RX A Volts Vcm = (A + B) / 2 SDn_TX or SDn_RX B Volts Differential Swing, VID or VOD = A – B Differential Peak Voltage, VDIFFp = |A – B| Differential Peak-Peak Voltage, VDIFFpp = 2*VDIFFp (not shown) Figure 57. Differential Voltage Definitions for Transmitter or Receiver To illustrate these definitions using real values, consider the case of a CML (Current Mode Logic) transmitter that has a common mode voltage of 2.25 V and each of its outputs, TD and TD, has a swing that goes between 2.5V and 2.0V. Using these values, the peak-to-peak voltage swing of each signal (TD or TD) is 500 mV p-p, which is referred as the single-ended swing for each signal. In this example, since the differential signaling environment is fully symmetrical, the transmitter output’s differential swing (VOD) has the same amplitude as each signal’s single-ended swing. The differential output signal ranges between 500 mV and –500 mV, in other words, VOD is 500 mV in one phase and –500 mV in the other phase. The peak differential voltage (VDIFFp) is 500 mV. The peak-to-peak differential voltage (V DIFFp-p) is 1000 mV p-p. 2.20.2 SerDes Reference Clocks The SerDes reference clock inputs are applied to an internal PLL whose output creates the clock used by the corresponding SerDes lanes. The SerDes reference clocks for PCI Express are SD1_REF_CLK and, SD1_REF_CLK. The SerDes reference clocks for the SATA and SGMII interfaces are SD2_REF_CLK and, SD2_REF_CLK. MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 92 Freescale Semiconductor High-Speed Serial Interfaces The following sections describe the SerDes reference clock requirements and some application information. 2.20.2.1 SerDes Reference Clock Receiver Characteristics Figure 58 shows a receiver reference diagram of the SerDes reference clocks. • • • • The supply voltage requirements for X2VDD are specified in Table 2 and Table 3. SerDes Reference Clock Receiver Reference Circuit Structure — The SDn_REF_CLK and SDn_REF_CLK are internally AC-coupled differential inputs as shown in Figure 58. Each differential clock input (SDn_REF_CLK or SDn_REF_CLK) has a 50-Ω termination to SGND (xcorevss) followed by on-chip AC-coupling. — The external reference clock driver must be able to drive this termination. — The SerDes reference clock input can be either differential or single-ended. See the Differential Mode and Single-ended Mode description below for further detailed requirements. The maximum average current requirement that also determines the common mode voltage range — When the SerDes reference clock differential inputs are DC coupled externally with the clock driver chip, the maximum average current allowed for each input pin is 8mA. In this case, the exact common mode input voltage is not critical as long as it is within the range allowed by the maximum average current of 8 mA (refer to the following bullet for more detail), since the input is AC-coupled on-chip. — This current limitation sets the maximum common mode input voltage to be less than 0.4 V (0.4 V/50 = 8 mA) while the minimum common mode input level is 0.1V above SnGND (xcorevss). For example, a clock with a 50/50 duty cycle can be produced by a clock driver with output driven by its current source from 0mA to 16mA (0–0.8 V), such that each phase of the differential input has a single-ended swing from 0 V to 800mV with the common mode voltage at 400mV. — If the device driving the SDn_REF_CLK and SDn_REF_CLK inputs cannot drive 50 Ω to SnGND (xcorevss) DC, or it exceeds the maximum input current limitations, then it must be AC-coupled off-chip. The input amplitude requirement — This requirement is described in detail in the following sections. 50 Ω SDn_REF_CLK Input Amp SDn_REF_CLK 50 Ω Figure 58. Receiver of SerDes Reference Clocks MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 93 High-Speed Serial Interfaces 2.20.2.2 DC Level Requirement for SerDes Reference Clocks The DC level requirement for the MPC8536E SerDes reference clock inputs is different depending on the signaling mode used to connect the clock driver chip and SerDes reference clock inputs as described below. • • Differential Mode — The input amplitude of the differential clock must be between 400mV and 1600mV differential peak-peak (or between 200mV and 800mV differential peak). In other words, each signal wire of the differential pair must have a single-ended swing less than 800mV and greater than 200mV. This requirement is the same for both external DC-coupled or AC-coupled connection. — For external DC-coupled connection, as described in section 2.20.2.1, the maximum average current requirements sets the requirement for average voltage (common mode voltage) to be between 100 mV and 400 mV. Figure 59 shows the SerDes reference clock input requirement for DC-coupled connection scheme. — For external AC-coupled connection, there is no common mode voltage requirement for the clock driver. Since the external AC-coupling capacitor blocks the DC level, the clock driver and the SerDes reference clock receiver operate in different command mode voltages. The SerDes reference clock receiver in this connection scheme has its common mode voltage set to SnGND. Each signal wire of the differential inputs is allowed to swing below and above the command mode voltage (SnGND). Figure 60 shows the SerDes reference clock input requirement for AC-coupled connection scheme. Single-ended Mode — The reference clock can also be single-ended. The SDn_REF_CLK input amplitude (single-ended swing) must be between 400mV and 800mV peak-peak (from Vmin to Vmax) with SDn_REF_CLK either left unconnected or tied to ground. — The SDn_REF_CLK input average voltage must be between 200 and 400 mV. Figure 61 shows the SerDes reference clock input requirement for single-ended signaling mode. — To meet the input amplitude requirement, the reference clock inputs might need to be DC or AC-coupled externally. For the best noise performance, the reference of the clock could be DC or AC-coupled into the unused phase (SDn_REF_CLK) through the same source impedance as the clock input (SDn_REF_CLK) in use. SDn_REF_CLK 200 mV < Input Amplitude or Differential Peak < 800 mV Vmax < 800 mV 100 mV < Vcm < 400 mV SDn_REF_CLK Vmin > 0 V Figure 59.

Single-Ended Reference Clock Input DC Requirements 2.20.2.3 Interfacing With Other Differential Signaling Levels With on-chip termination to SnGND (xcorevss), the differential reference clocks inputs are HCSL (High-Speed Current Steering Logic) compatible DC-coupled. Many other low voltage differential type outputs like LVDS (Low Voltage Differential Signaling) can be used but may need to be AC-coupled due to the limited common mode input range allowed (100 to 400 mV) for DC-coupled connection. LVPECL (Low Voltage Positive Emitter-Coupled Logic) outputs can produce signal with too large amplitude and may need to be DC-biased at clock driver output first, then followed with series attenuation resistor to reduce the amplitude, in addition to AC-coupling. NOTE Figure 62 to Figure 65 below are for conceptual reference only. Due to the fact that clock driver chip's internal structure, output impedance and termination requirements are different between various clock driver chip manufacturers, it is very possible that the clock circuit reference designs provided by clock driver chip vendor are different from what is shown below. They might also vary from one vendor to the other. Therefore, Freescale Semiconductor can neither provide the optimal clock driver reference circuits, nor guarantee the correctness of the following clock driver connection reference circuits. The system designer is recommended to contact the selected clock driver chip vendor for the optimal reference circuits with the MPC8536E SerDes reference clock receiver requirement provided in this document. MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 95 High-Speed Serial Interfaces Figure 62 shows the SerDes reference clock connection reference circuits for HCSL type clock driver.

DC-Coupled Differential Connection with HCSL Clock Driver (Reference Only) Figure 63 shows the SerDes reference clock connection reference circuits for LVDS type clock driver. Since LVDS clock driver’s common mode voltage is higher than the MPC8536E SerDes reference clock input’s allowed range (100 to 400mV), AC-coupled connection scheme must be used. It assumes the LVDS output driver features 50-Ω termination resistor. It also assumes that the LVDS transmitter establishes its own common mode level without relying on the receiver or other external component.

AC-Coupled Differential Connection with LVDS Clock Driver (Reference Only) MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 96 Freescale Semiconductor High-Speed Serial Interfaces Figure 64 shows the SerDes reference clock connection reference circuits for LVPECL type clock driver. Since LVPECL driver’s DC levels (both common mode voltages and output swing) are incompatible with MPC8536E SerDes reference clock input’s DC requirement, AC-coupling has to be used. Figure 64 assumes that the LVPECL clock driver’s output impedance is 50Ω. R1 is used to DC-bias the LVPECL outputs prior to AC-coupling. Its value could be ranged from 140Ω to 240Ω depending on clock driver vendor’s requirement. R2 is used together with the SerDes reference clock receiver’s 50-Ω termination resistor to attenuate the LVPECL output’s differential peak level such that it meets the MPC8536E SerDes reference clock’s differential input amplitude requirement (between 200mV and 800mV differential peak). For example, if the LVPECL output’s differential peak is 900mV and the desired SerDes reference clock input amplitude is selected as 600mV, the attenuation factor is 0.67, which requires R2 = 25Ω. Please consult clock driver chip manufacturer to verify whether this connection scheme is compatible with a particular clock driver chip.

Phase noise less than 100KHz can be tracked by the PLL and data recovery loops and is less of a problem. Phase noise above 15MHz is filtered by the PLL. The most problematic phase noise occurs in the 1-15MHz range. The source impedance of the clock driver should be 50 ohms to match the transmission line and reduce reflections which are a source of noise to the system.

It is measured using a 200 mV window centered on the median cross point where SDn_REF_CLK rising meets SDn_REF_CLK falling. The median cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate calculations. The Rise Edge Rate of SDn_REF_CLK should be compared to the Fall Edge Rate of SDn_REF_CLK, the maximum allowed difference should not exceed 20% of the slowest edge rate. See Figure 67.

There are two eye diagrams that must be met for the transmitter. Both eye diagrams must be aligned in time using the jitter median to locate the center of the eye diagram. The different eye diagrams will differ in voltage depending whether it is a transition bit or a de-emphasized bit. The exact reduced voltage level of the de-emphasized bit will always be relative to the transition bit. The eye diagram must be valid for any 250 consecutive UIs. A recovered TX UI is calculated over 3500 consecutive unit intervals of sample data. The eye diagram is created using all edges of the 250 consecutive UI in the center of the 3500 UI used for calculating the TX UI. NOTE It is recommended that the recovered TX UI is calculated using all edges in the 3500 consecutive UI interval with a fit algorithm using a minimization merit function (that is, least squares and median deviation fits).

The test load in Figure 71 should be used as the RX device when taking measurements (also refer to the Receiver compliance eye diagram shown in Figure 70). If the clocks to the RX and TX are not derived from the same reference clock, the TX UI recovered from 3500 consecutive UI must be used as a reference for the eye diagram. 3. A TRX-EYE = 0.40 UI provides for a total sum of 0.60 UI deterministic and random jitter budget for the Transmitter and interconnect collected any 250 consecutive UIs. The TRX-EYE-MEDIAN-to-MAX-JITTER specification ensures a jitter distribution in which the median and the maximum deviation from the median is less than half of the total. UI jitter budget collected over any 250 consecutive TX UIs. It should be noted that the median is not the same as the mean. The jitter median describes the point in time where the number of jitter points on either side is approximately equal as opposed to the averaged time value. If the clocks to the RX and TX are not derived from the same reference clock, the TX UI recovered from 3500 consecutive UI must be used as the reference for the eye diagram. 4. The Receiver input impedance shall result in a differential return loss greater than or equal to 15 dB with the D+ line biased to 300 mV and the D- line biased to -300 mV and a common mode return loss greater than or equal to 6 dB (no bias required) over a frequency range of 50 MHz to 1.25 GHz. This input impedance requirement applies to all valid input levels. The reference impedance for return loss measurements for is 50 ohms to ground for both the D+ and D- line (that is, as measured by a Vector Network Analyzer with 50 ohm probes - see Figure 71). Note: that the series capacitors CTX is optional for the return loss measurement. 5. Impedance during all LTSSM states. When transitioning from a Fundamental Reset to Detect (the initial state of the LTSSM) there is a 5 ms transition time before Receiver termination values must be met on all un-configured Lanes of a Port. 6. The RX DC Common Mode Impedance that exists when no power is present or Fundamental Reset is asserted. This helps ensure that the Receiver Detect circuit will not falsely assume a Receiver is powered on when it is not. This term must be measured at 300 mV above the RX ground. 7. It is recommended that the recovered TX UI is calculated using all edges in the 3500 consecutive UI interval with a fit algorithm using a minimization merit function. Least squares and median deviation fits have worked well with experimental and simulated data. 2.22 Receiver Compliance Eye Diagrams The RX eye diagram in Figure 70 is specified using the passive compliance/test measurement load (see Figure 71) in place of any real PCI Express RX component. Note: In general, the minimum Receiver eye diagram measured with the compliance/test measurement load (see Figure 71) will be larger than the minimum Receiver eye diagram measured over a range of systems at the input Receiver of any real PCI Express component. The degraded eye diagram at the input Receiver is due to traces internal to the package as well as silicon parasitic characteristics which cause the real PCI Express component to vary in impedance from the compliance/test measurement load. The input Receiver eye diagram is implementation specific and is not specified. RX component designer should provide additional margin to adequately compensate for the degraded minimum Receiver eye diagram (shown in Figure 70) expected at the input Receiver based on some adequate combination of system simulations and the Return Loss measured looking into the RX package and silicon. The RX eye diagram must be aligned in time using the jitter median to locate the center of the eye diagram. The eye diagram must be valid for any 250 consecutive UIs.

Caution: The CCB to SYSCLK ratio and e500 core to CCB ratio settings must be chosen such that the resulting SYSCLK frequency, e500 (core) frequency, and CCB frequency do not exceed their respective maximum or minimum operating frequencies.

The processor core frequency speed bins listed also reflect the maximum platform (CCB) and DDR data rate frequency supported by production test. Running CCB and/or DDR data rate higher than the limit shown above, although logically possible via valid clock ratio setting in some condition, is not supported. The DDR memory controller can run in either synchronous or asynchronous mode. When running in synchronous mode, the memory bus is clocked relative to the platform clock frequency. When running in asynchronous mode, the memory bus is clocked with its own dedicated PLL. Table 74 provides the clocking specifications for the memory bus. Table 74.

The Memory bus clock refers to the MPC8536E memory controllers’ MCK[0:5] and MCK[0:5] output clocks, running at half of the DDR data rate. 3. In synchronous mode, the memory bus clock speed is half the platform clock frequency. In other words, the DDR data rate is the same as the platform (CCB) frequency. If the desired DDR data rate is higher than the platform (CCB) frequency, asynchronous mode must be used. 4. In asynchronous mode, the memory bus clock speed is dictated by its own PLL. See Section 2.23.4, “DDR/DDRCLK PLL Ratio.” The memory bus clock speed must be less than or equal to the CCB clock rate which in turn must be less than the DDR data rate. MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 107 Clocking 2.23.2 CCB/SYSCLK PLL Ratio The CCB clock is the clock that drives the e500 core complex bus (CCB), and is also called the platform clock. The frequency of the CCB is set using the following reset signals, as shown in Table 75: • • SYSCLK input signal Binary value on LA[28:31] at power up Note that there is no default for this PLL ratio; these signals must be pulled to the desired values.

Table 77 describes the clock ratio between the DDR memory controller complex and the DDR/DDRCLK PLL reference clock, DDRCLK, which is not the memory bus clock. When synchronous mode is selected, the memory buses are clocked at half the CCB clock rate. The default mode of operation is for the DDR data rate for the DDR controller to be equal to the CCB clock rate in synchronous mode, or the resulting DDR PLL rate in asynchronous mode. In asynchronous mode, the DDR PLL rate to DDRCLK ratios listed in Table 77 reflects the DDR data rate to DDRCLK ratio, since the DDR PLL rate in asynchronous mode means the DDR data rate resulting from DDR PLL output. MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 108 Freescale Semiconductor Clocking Please note that the DDR PLL reference clock input, DDRCLK, is only required in asynchronous mode. The DDRCLKDR configuration register in the Global Utilities block allows the DDR controller to be run in a divided down mode where the DDR bus clock is half the speed of the default configuration. Changing of these defaults must be completed prior to initialization of the DDR controller. Table 77.

The PCI input clock can be applied from SYSCLK in synchronous mode or PCI1_CLK in asynchronous mode. For specifications on the PCI1_CLK, refer to the PCI 2.2 Specification. The use of PCI1_CLK is optional if SYSCLK is in the range of 33–66 MHz. If SYSCLK is outside this range then use of PCI1_CLK is required as a separate PCI clock source, asynchronous with respect to SYSCLK.

System Level Thermal Model for MPC8536E (Not to Scale) The Flotherm library files of the parts have a dense grid to accurately capture the laminar boundary layer for flow over the part in standard JEDEC environments, as well as the heat spreading in the board under the package. In a real system, however, the part will require a heat sink to be mounted on it. In this case, the predominant heat flow path will be from the die to the heat sink. Grid density lower than currently in the package library file will suffice for these simulations. The user will need to determine the optimal grid for their specific case. MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 112 Freescale Semiconductor Thermal 2.24.3 Thermal Management Information This section provides thermal management information for the flip chip plastic ball grid array (FC-PBGA) 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. The recommended attachment method to the heat sink is illustrated in Figure 73. The heat sink should be attached to the printed-circuit board with the spring force centered over the die. This spring force should not exceed 10 pounds force (45 Newton). FC-PBGA Package Heat Sink Heat Sink Clip Thermal Interface Material Die Printed-Circuit Board Figure 73. Package Exploded Cross-Sectional View with Several Heat Sink Options The system board designer can choose between several types of heat sinks to place on the device. Ultimately, the final selection of an appropriate heat sink depends on many factors, such as thermal performance at a given air velocity, spatial volume, mass, attachment method, assembly, and cost. Several heat sinks offered by Aavid Thermalloy, Advanced Thermal Solutions, Alpha Novatech, IERC, Chip Coolers, Millennium Electronics, and Wakefield Engineering offer different heat sink-to-ambient thermal resistances, that will allow the MPC8536E to function in various environments. 2.24.3.1 Internal Package Conduction Resistance For the packaging technology, shown in Table 70, the intrinsic internal conduction thermal resistance paths are as follows: • • The die junction-to-case thermal resistance The die junction-to-board thermal resistance MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 113 System Clocking Figure 74 depicts the primary heat transfer path for a package with an attached heat sink mounted to a printed-circuit board.

Package with Heat Sink Mounted to a Printed-Circuit Board The heat sink removes most of the heat from the device for most applications. Heat generated on the active side of the chip is conducted through the silicon and through the heat sink attach material (or thermal interface material), and finally to the heat sink. The junction-to-case thermal resistance is low enough that the heat sink attach material and heat sink thermal resistance are the dominant terms. 2.24.3.2 Thermal Interface Materials A thermal interface material is required at the package-to-heat sink interface to minimize the thermal contact resistance. The performance of thermal interface materials improves with increased contact pressure. This performance characteristic chart is generally provided by the thermal interface vendors. 3 Hardware Design Considerations This section provides electrical and thermal design recommendations for successful application of the MPC8536E. 3.1 System Clocking This device includes seven PLLs: • • • • • • • The platform PLL generates the platform clock from the externally supplied SYSCLK input. The frequency ratio between the platform and SYSCLK is selected using the platform PLL ratio configuration bits as described in Section 2.23.2, “CCB/SYSCLK PLL Ratio.” The e500 core PLL generates the core clock as a slave to the platform clock. The frequency ratio between the e500 core clock and the platform clock is selected using the e500 PLL ratio configuration bits as described in Section 2.23.3, “e500 Core PLL Ratio/” The PCI PLL generates the clocking for the PCI bus The local bus PLL generates the clock for the local bus. There is a PLL for the SerDes1 block to be used for PCI Express interface There is a PLL for the SerDes2 block to be used for SGMII and SATA interfaces. The DDR PLL generates the DDR clock from the externally supplied DDRCLK input in asynchronous mode. The frequency ratio between the DDR clock and DDRCLK is described in Section 2.23.4, “DDR/DDRCLK PLL Ratio.” MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 114 Freescale Semiconductor Power Supply Design and Sequencing 3.2 3.2.1 Power Supply Design and Sequencing PLL Power Supply Filtering Each of the PLLs listed above is provided with power through independent power supply pins (AVDD_PLAT, AVDD_CORE, AVDD_PCI, AVDD_LBIU, and AVDD_SRDS respectively). The AVDD level should always be equivalent to VDD, and preferably these voltages will be derived directly from VDD through a low frequency filter scheme such as the following. There are a number of ways to reliably provide power to the PLLs, but the recommended solution is to provide independent filter circuits per PLL power supply as illustrated in Figure 75, one to each of the AVDD pins. By providing independent filters to each PLL the opportunity to cause noise injection from one PLL to the other is reduced. This circuit is intended to filter noise in the PLLs resonant frequency range from a 500 kHz to 10 MHz range. It should be built with surface mount capacitors with minimum Effective Series Inductance (ESL). Consistent with the recommendations of Dr. Howard Johnson in High Speed Digital Design: A Handbook of Black Magic (Prentice Hall, 1993), multiple small capacitors of equal value are recommended over a single large value capacitor. Each circuit should be placed as close as possible to the specific AVDD pin being supplied to minimize noise coupled from nearby circuits. It should be possible to route directly from the capacitors to the AVDD pin, which is on the periphery of 783 FC-PBGA the footprint, without the inductance of vias. Figure 75 shows the PLL power supply filter Circuit. 10 Ω V DD AVDD 2.2 µF 2.2 µF GND Low ESL Surface Mount Capacitors Figure 75. MPC8536E PLL Power Supply Filter Circuit The AVDD_SRDSn signals provides power for the analog portions of the SerDes PLL. To ensure stability of the internal clock, the power supplied to the PLL is filtered using a circuit similar to the one shown in following Figure 76. For maximum effectiveness, the filter circuit is placed as closely as possible to the AVDD_SRDSn balls to ensure it filters out as much noise as possible. The ground connection should be near the AVDD_SRDSn balls. The 0.003-µF capacitor is closest to the balls, followed by the 1-µF capacitor, and finally the 1 ohm resistor to the board supply plane. The capacitors are connected from AVDD_SRDSn to the ground plane. Use ceramic chip capacitors with the highest possible self-resonant frequency. All traces should be kept short, wide and direct. SnVDD 1.0 Ω AVDD - SRDS 2.2 µF 1 2.2 µF 1 0.003 µF GND 1. An 0805 sized capacitor is recommended for system initial bring-up Figure 76. SerDes PLL Power Supply Filter Circuit Note the following: • AVDD should be a filtered version of SVDD. • Signals on the SerDes interface are fed from the XVDD power plane. MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 115 Pin States in Deep Sleep State 3.3 Pin States in Deep Sleep State In all low power mode by default, all input and output pads remain driven as per normal functional operation. The inputs remain enabled. The exception is that in Deep Sleep mode, GCR[DEEPSLEEP_Z] can be used to tristate a subset of output pads, and disable the receivers of input pads as defined in Table 1. See the MPC8536E PowerQUICC™ III Integrated Processor Reference Manual for details. 3.4 Decoupling Recommendations Due to large address and data buses, and high operating frequencies, the device 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 MPC8536E system, and the device 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, TVDD, BVDD, OVDD, GVDD, and LVDD pin of the device. These decoupling capacitors should receive their power from separate VDD,TVDD, BVDD, OVDD, GVDD, and LVDD, and GND power planes in the PCB, utilizing short low impedance traces to minimize inductance. Capacitors must be placed directly under the device using a standard escape pattern as much as possible. If some caps are to be placed surrounding the part it should be routed with short and large trace to minimize the inductance. These capacitors should have a value of 0.1 µF. Only ceramic SMT (surface mount technology) capacitors should be used to minimize lead inductance, preferably 0402 or 0603 sizes. In addition, it is recommended that there be several bulk storage capacitors distributed around the PCB, feeding the VDD, TVDD, BVDD, 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 µF (AVX TPS tantalum or Sanyo OSCON). However, customers should work directly with their power regulator vendor for best values types and quantity of bulk capacitors. 3.5 SerDes Block Power Supply Decoupling Recommendations he SerDes1 and SerDes2 blocks require a clean, tightly regulated source of power (SnVDD and XnVDD) to ensure low jitter on transmit and reliable recovery of data in the receiver. An appropriate decoupling scheme is outlined below. Only surface mount technology (SMT) capacitors should be used to minimize inductance. Connections from all capacitors to power and ground should be done with multiple vias to further reduce inductance. • First, the board should have at least 10 x 10-nF SMT ceramic chip capacitors as close as possible to the supply balls of the device. Where the board has blind vias, these capacitors should be placed directly below the chip supply and ground connections. Where the board does not have blind vias, these capacitors should be placed in a ring around the device as close to the supply and ground connections as possible. • Second, there should be a 1-µF ceramic chip capacitor from each SerDes supply (SnVDD and XnVDD) to the board ground plane on each side of the device. This should be done for all SerDes supplies. • Third, between the device and any SerDes voltage regulator there should be a 10-µF, low equivalent series resistance (ESR) SMT tantalum chip capacitor and a 100-µF, low ESR SMT tantalum chip capacitor. This should be done for all SerDes supplies. 3.6 Connection Recommendations To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal level. All unused active low inputs should be tied to VDD,TVDD, BVDD, OVDD, GVDD, and LVDD as required. All 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,TVDD, BVDD, OVDD, GVDD, and LVDD and GND pins of the device. MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 116 Freescale Semiconductor Pull-Up and Pull-Down Resistor Requirements 3.7 Pull-Up and Pull-Down Resistor Requirements The MPC8536E requires weak pull-up resistors (2–10 kΩ is recommended) on open drain type pins including I2C pins and MPIC interrupt pins. Correct operation of the JTAG interface requires configuration of a group of system control pins as demonstrated in Figure 78. Care must be taken to ensure that these pins are maintained at a valid deasserted state under normal operating conditions as most have asynchronous behavior and spurious assertion will give unpredictable results. The following pins must NOT be pulled down during power-on reset: TSEC1_TXD[3], HRESET_REQ, TRIG_OUT/READY/QUIESCE, MSRCID[2:4], ASLEEP. The UART_SOUT[0:1] and TEST_SEL pins must be set to a proper state during POR configuration. Please refer to the pinlist table (see Table 62) of the individual device for more details. See the PCI 2.2 specification for all pull-ups required for PCI. 3.8 Output Buffer DC Impedance The MPC8536E drivers are characterized over process, voltage, and temperature. For all buses, the driver is a push-pull single-ended driver type (open drain for I2C). To measure Z0 for the single-ended drivers, an external resistor is connected from the chip pad to OVDD or GND. Then, the value of each resistor is varied until the pad voltage is OVDD/2 (see Figure 77). The output impedance is the average of two components, the resistances of the pull-up and pull-down devices. When data is held high, SW1 is closed (SW2 is open) and RP is trimmed until the voltage at the pad equals OVDD/2. RP then becomes the resistance of the pull-up devices. RP and RN are designed to be close to each other in value. Then, Z0 = (RP + RN)/2. OV DD RN SW2 Data Pad SW1 RP OGND Figure 77. Driver Impedance Measurement Table 81 summarizes the signal impedance targets. The driver impedances are targeted at minimum VDD, nominal OVDD, 105° C.

See Table 1. 3.9 Configuration Pin Muxing The MPC8536E provides the user with power-on configuration options which can be set through the use of external pull-up or pull-down resistors of 4.7 kΩ on certain output pins (see customer visible configuration pins). These pins are generally used as output only pins in normal operation. While HRESET is asserted however, these pins are treated as inputs. The value presented on these pins while HRESET is asserted, is latched when HRESET deasserts, at which time the input receiver is disabled and the I/O circuit takes on its normal function. Most of these sampled configuration pins are equipped with an on-chip gated resistor of approximately 20 kΩ. This value should permit the 4.7-kΩ resistor to pull the configuration pin to a valid logic low level. The pull-up resistor is enabled only during HRESET (and for platform /system clocks after HRESET deassertion to ensure capture of the reset value). When the input receiver is disabled the pull-up is also, thus allowing functional operation of the pin as an output with minimal signal quality or delay disruption. The default value for all configuration bits treated this way has been encoded such that a high voltage level puts the device into the default state and external resistors are needed only when non-default settings are required by the user. Careful board layout with stubless connections to these pull-down resistors coupled with the large value of the pull-down resistor should minimize the disruption of signal quality or speed for output pins thus configured. The platform PLL ratio and e500 PLL ratio configuration pins are not equipped with these default pull-up devices. 3.10 JTAG Configuration Signals Correct operation of the JTAG interface requires configuration of a group of system control pins as demonstrated in Figure 78. Care must be taken to ensure that these pins are maintained at a valid deasserted state under normal operating conditions as most have asynchronous behavior and spurious assertion will give unpredicatable results. Boundary-scan testing is enabled through the JTAG interface signals. The TRST signal is optional in the IEEE 1149.1 specification, but it is provided on all processors built on Power Architecture technology. The device requires TRST to be asserted during power-on reset flow to ensure that the JTAG boundary logic does not interfere with normal chip operation. While the TAP controller can be forced to the reset state using only the TCK and TMS signals, generally systems assert TRST during the power-on reset flow. Simply tying TRST to HRESET is not practical because the JTAG interface is also used for accessing the common on-chip processor (COP), which implements the debug interface to the chip. The COP function of these processors allow 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 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, then the COP reset signals must be merged into these signals with logic. The arrangement shown in Figure 78 allows the COP port to independently assert HRESET or TRST, while ensuring that the target can drive HRESET as well. MPC8536E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 2 118 Freescale Semiconductor JTAG Configuration Signals The COP interface has a standard header, shown in Figure 79, for connection to the target system, and is based on the 0.025" square-post, 0.100" centered header assembly (often called a Berg header). The connector typically has pin 14 removed as a connector key. The COP header adds many benefits such as breakpoints, watchpoints, register and memory examination/modification, and other standard debugger features. An inexpensive option can be to leave the COP header unpopulated until needed. There is no standardized way to number the COP header; 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 79 is common to all known emulators. 3.10.1 Termination of Unused Signals If the JTAG interface and COP header will not be used, Freescale recommends the following connections: • TRST should be tied to HRESET through a 0 kΩ isolation resistor so that it is asserted when the system reset signal (HRESET) is asserted, ensuring that the JTAG scan chain is initialized during the power-on reset flow. Freescale recommends that the COP header be designed into the system as shown in Figure 78. If this is not possible, the isolation resistor will allow future access to TRST in case a JTAG interface may need to be wired onto the system in future debug situations. • No pull-up/pull-down is required for TDI, TMS, or TDO.

The COP port and target board should be able to independently assert HRESET and TRST to the processor in order to fully control the processor as shown here. 2. Populate this with a 10 Ω resistor for short-circuit/current-limiting protection. 3. The KEY location (pin 14) is not physically present on the COP header. 4. Although pin 12 is defined as a No-Connect, some debug tools may use pin 12 as an additional GND pin for improved signal integrity. 5. This switch is included as a precaution for BSDL testing. The switch should be closed to position A during BSDL testing to avoid accidentally asserting the TRST line. If BSDL testing is not being performed, this switch should be closed to position B. 6. Asserting SRESET causes a machine check interrupt to the e500 core. Figure 78.
