During the power ramp up, before the power supplies are stable and if the I/O voltages are supplied before the core voltage, there may be a period of time that all input and output pins will actively be driven and cause contention and excessive current. To avoid actively driving the I/O pins and to eliminate excessive current draw, apply the core voltages (VDD and AVDD) before the I/O voltages and assert PORESET before the power supplies fully ramp up. VDD and AVDD must reach 90% of their nominal value before GVDD, LVDD, and OVDD reach 10% of their value, see Figure 3. I/O voltage supplies, GVDD, LVDD, and OVDD do not have any ordering requirements with respect to one another. V I/O Voltage (GVDD, LVDD, and OVDD) Core Voltage (VDD, AVDD) 90% 0.7 V 0 t Figure 3. Power-Up Sequencing Example Please note that the SerDes power supply (L[1,2]_nVDD) should follow the same timing as the core supply (VDD). The opposite sequence applies to the power down requirements. The I/O supplies must go down first and immediately followed by the core and PLL supplies. 3 Power Characteristics Table 5.

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 system clock speed. (The maximum frequency is the maximum platform frequency divided by 64.) 3 This parameter is dependent on the system clock speed. (That is, for a system clock of 267 MHz, the maximum frequency is 8.3 MHz and the minimum frequency is 1.2 MHz; for a system clock of 375 MHz, the maximum frequency is 11.7 MHz and the minimum frequency is 1.7 MHz.) 4 Guaranteed by design. 5t plb_clk is the platform (CSB) clock divided according to the SCCR[TSEC1CM].

The eSDHC controller always uses the falling edge of the SD_CLK in order to drive the SD_DAT[0:3]/CMD as outputs and sample the SD_DAT[0:3] as inputs. This behavior is true for both fulland high-speed modes. Note that this is a non-standard implementation, as the SD card specification assumes that in high-speed mode, that data will be driven at the rising edge of the clock. MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 48 Freescale Semiconductor Enhanced Secure Digital Host Controller (eSDHC) Due to the special implementation of the eSDHC, there are constraints regarding the clock and data signals propagation delay on the user board. The constraints are for minimum and maximum delays, as well as skew between the CLK and DAT/CMD signals. In full speed mode, there is no need to add special delay on the data or clock signals. The user should make sure to meet the timing requirements as described further within this document. If the system is designed to support both high-speed and full-speed cards, the high-speed constraints should be fulfilled. If the systems is designed to operate up to 25 MHz only, full-speed mode is recommended. 11.1 eSDHC DC Electrical Characteristics Table 45. eSDHC interface DC Electrical Characteristics Parameter Symbol VIH VIL IIN VOH VOL Condition — — — IOH = –100 uA, at OVDD(min) IOL = +100 uA, at OVDD(min) Min 0.625 × OVDD –0.3 — 0.75 × OVDD — Max OVDD + 0.3 0.25 × OV DD ±30 — 0.125 × OVDD Unit V V μA V V Table 45 provides the DC electrical characteristics for the eSDHC (SD/MMC) interface of the device.

High Speed Input Path For the input path, the device eSDHC expects to sample the data 1.5 internal clock cycles after it was driven by the SD card. Since in this mode the SD card drives the data at the rising edge of the clock, a sufficient delay to the clock and the data must exist to ensure it will not be sampled at the wrong internal clock falling edge. Note that the internal clock which is guaranteed to be 50% duty cycle is used to sample the data, and therefore used in the equations.

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 will result in a differential return loss greater than or equal to 10 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 Ω to ground for both the D+ and D– line (that is, as measured by a vector network analyzer with 50-Ω probes, see Figure 48). 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 unconfigured 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 does 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. 15.5 Receiver Compliance Eye Diagrams The Rx eye diagram in Figure 47 is specified using the passive compliance/test measurement load (see Figure 48) in place of any real PCI Express Rx component. In general, the minimum receiver eye diagram measured with the compliance/test measurement load (see Figure 48) is 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 MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 71 PCI Express parasitic characteristics that 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 47) expected at the input receiver based on an 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. 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 The reference impedance for return loss measurements is 50. to ground for both the D+ and D– line (that is, as measured by a Vector Network Analyzer with 50. probes—see Figure 48). Note that the series capacitors, CPEACCTX, are optional for the return loss measurement.

NOTE The allowance of the measurement point to be within 0.2 inches of the package pins is meant to acknowledge that package/board routing may benefit from D+ and D– not being exactly matched in length at the package pin boundary.

SPI AC Timing in Master Mode (Internal Clock) Diagram 20 High-Speed Serial Interfaces (HSSI) The MPC8378E features two serializer/deserializer (SerDes) interfaces to be used for high-speed serial interconnect applications. See Table 1 for the interfaces supported. 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. 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 54 shows how the signals are defined. For illustration purpose, 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. • 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. • Differential Output Voltage, VOD (or Differential Output Swing): The differential output voltage (or swing) of the transmitter, VOD, is defined as the difference of the two complimentary output voltages: VSDn_TX – VSDn_TX. The VOD value can be either positive or negative. MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 78 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) • • • • • Differential Input Voltage, VID (or Differential Input Swing): The differential input voltage (or swing) of the receiver, VID, is defined as the difference of the two complimentary input voltages: VSDn_RX – VSDn_RX. The VID value can be either positive or negative. 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. 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 VTX-DIFFp-p = 2 × |VOD|. Differential Waveform The differential waveform is constructed by subtracting the inverting signal (SDn_TX, for example) from the non-inverting signal (SDn_TX, for example) within a differential pair. There is only one signal trace curve in a differential waveform. The voltage represented in the differential waveform is not referenced to ground. Refer to Figure 63 as an example for differential waveform. 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) ÷ 2 = (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 54. Differential Voltage Definitions for Transmitter or Receiver MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 79 High-Speed Serial Interfaces (HSSI) 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 2.5 V and 2.0 V. Using these values, the peak-to-peak voltage swing of each signal (TD or TD) is 500 mVp-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 (VDIFFp-p) is 1000 mVp-p. 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 inputs are SD1_REF_CLK and SD1_REF_CLK for both lanes of SerDes1, and SD2_REF_CLK and SD2_REF_CLK for both lanes of SerDes2. The following sections describe the SerDes reference clock requirements and some application information. 20.2.1 SerDes Reference Clock Receiver Characteristics Figure 55 shows a receiver reference diagram of the SerDes reference clocks. • 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 55. Each differential clock input (SDn_REF_CLK or SDn_REF_CLK) has a 50 Ω termination to SGND_SRDSn (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. Refer to 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 8 mA. 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 0.1 V above SGND_SRDSn (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 0 mA to 16 mA (0–0.8 V), such that each phase of the differential input has a single-ended swing from 0 V to 800 mV with the common mode voltage at 400 mV. MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 80 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) • — If the device driving the SDn_REF_CLK and SDn_REF_CLK inputs cannot drive 50 Ω to SGND_SRDSn (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 55. Receiver of SerDes Reference Clocks 20.2.2 DC Level Requirement for SerDes Reference Clocks The DC level requirement for the device 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 400 mV and 1600 mV differential peak-peak (or between 200 mV and 800 mV differential peak). In other words, each signal wire of the differential pair must have a single-ended swing less than 800 mV and greater than 200 mV. This requirement is the same for both external DC-coupled or AC-coupled connection. — For external DC-coupled connection, as described in Section 20.2.1, “SerDes Reference Clock Receiver Characteristics,” the maximum average current requirements sets the requirement for average voltage (common mode voltage) to be between 100 mV and 400 mV. Figure 56 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 SGND_SRDSn. Each signal wire of the differential inputs is allowed to swing below and above the command mode voltage (SGND_SRDSn). Figure 57 shows the SerDes reference clock input requirement for AC-coupled connection scheme. MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 81 High-Speed Serial Interfaces (HSSI) • Single-ended Mode — The reference clock can also be single-ended. The SD _REF_CLK input amplitude (single-ended swing) must be between 400 mV and 800 mVp-p (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 mV and 400 mV. Figure 58 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. 200 mV < Input Amplitude or Differential Peak < 800 mV SDn_REF_CLK Vmax < 800 mV 100 mV < V cm < 400 mV SDn_REF_CLK Vmin > 0 V Figure 56.

Single-Ended Reference Clock Input DC Requirements MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 82 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) 20.2.3 Interfacing With Other Differential Signaling Levels The following list provides information about interfacing with other differential signaling levels. • With on-chip termination to SGND_SRDSn (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 mV to 400 mV) for DC-coupled connection. • LVPECL 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 59 to Figure 62 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 the 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 device SerDes reference clock receiver requirement provided in this document.

DC-Coupled Differential Connection with HCSL Clock Driver (Reference Only) Figure 60 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 device SerDes reference clock input’s allowed range (100 to 400 mV), AC-coupled connection scheme must be used. It assumes the LVDS output driver features a 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) Figure 61 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 device SerDes reference clock input’s DC requirement, AC-coupling has to be used. Figure 61 assumes MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 84 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) that the LVPECL clock driver’s output impedance is 50 Ω. R1 is used to DC-bias the LVPECL outputs prior to AC-coupling. Its value could be ranged from 140 Ω to 240 Ω 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 device SerDes reference clock’s differential input amplitude requirement (between 200 mV and 800 mV differential peak). For example, if the LVPECL output’s differential peak is 900 mV and the desired SerDes reference clock input amplitude is selected as 600 mV, the attenuation factor is 0.67, which requires R2 = 25 Ω. Please consult clock driver chip manufacturer to verify whether this connection scheme is compatible with a particular clock driver chip.

Single-Ended Connection (Reference Only) 20.2.4 AC Requirements for SerDes Reference Clocks The clock driver selected should provide a high quality reference clock with low phase noise and cycle-to-cycle jitter. Phase noise less than 100 KHz can be tracked by the PLL and data recovery loops and is less of a problem. Phase noise above 15 MHz is filtered by the PLL. The most problematic phase noise occurs in the 1–15 MHz range. The source impedance of the clock driver should be 50 Ω to match the transmission line and reduce reflections which are a source of noise to the system.

MPC8378E Clock Subsystem The primary clock source for the device can be one of two inputs, CLKIN or PCI_CLK, depending on whether the device is configured in PCI host or PCI agent mode. When the device is configured as a PCI host device, CLKIN is its primary input clock. CLKIN feeds the PCI clock divider (÷2) and the multiplexors for PCI_SYNC_OUT and PCI_CLK_OUT. The CFG_CLKIN_DIV configuration input selects whether CLKIN or CLKIN/2 is driven out on the PCI_SYNC_OUT signal. The OCCR[PCICOEn] parameters select whether CFG_CLKIN_DIV is driven out on the PCI_CLK_OUTn signals. PCI_SYNC_OUT is connected externally to PCI_SYNC_IN to allow the internal clock subsystem to synchronize to the system PCI clocks. PCI_SYNC_OUT must be connected properly to PCI_SYNC_IN, with equal delay to all PCI agent devices in the system, to allow the device to function. When the device is configured as a PCI agent device, PCI_CLK is the primary input clock. When the device is configured as a PCI agent device the CLKIN signal should be tied to GND. MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 106 Freescale Semiconductor Clocking As shown in Figure 67, the primary clock input (frequency) is multiplied up by the system phase-locked loop (PLL) and the clock unit to create the coherent system bus clock (csb_clk), the internal clock for the DDR controller (ddr_clk), and the internal clock for the local bus interface unit (lbiu_clk). The csb_clk frequency is derived from a complex set of factors that can be simplified into the following equation: csb_clk = {PCI_SYNC_IN × (1 + CFG_CLKIN_DIV)} × SPMF In PCI host mode, PCI_SYNC_IN × (1 + CFG_CLKIN_DIV) is the CLKIN frequency. The csb_clk serves as the clock input to the e300 core. A second PLL inside the e300 core multiplies up the csb_clk frequency to create the internal clock for the e300 core (core_clk). The system and core PLL multipliers are selected by the SPMF and COREPLL fields in the reset configuration word low (RCWL) which is loaded at power-on reset or by one of the hard-coded reset options. See Chapter 4, “Reset, Clocking, and Initialization,” in the MPC8379E Reference Manual for more information on the clock subsystem. The internal ddr_clk frequency is determined by the following equation: ddr_clk = csb_clk × (1 + RCWL[DDRCM]) Note that ddr_clk is not the external memory bus frequency; ddr_clk passes through the DDR clock divider (÷2) to create the differential DDR memory bus clock outputs (MCK and MCK). However, the data rate is the same frequency as ddr_clk. The internal lbiu_clk frequency is determined by the following equation: lbiu_clk = csb_clk × (1 + RCWL[LBCM]) Note that lbiu_clk is not the external local bus frequency; lbiu_clk passes through the LBIU clock divider to create the external local bus clock outputs (LCLK[0:2]). The eLBC clock divider ratio is controlled by LCCR[CLKDIV]. Some of the internal units may be required to be shut off or operate at lower frequency than the csb_clk frequency. Those units have a default clock ratio that can be configured by a memory mapped register after the device comes out of reset. Table 68 specifies which units have a configurable clock frequency.

The value of SCCR[xCM] must be programmed such that the maximum internal operating frequency of the Security core, USB modules, SATA, and eSDHC will not exceed their respective value listed in this table. 2 The DDR data rate is 2× the DDR memory bus frequency. 3 The local bus frequency is 1/2, 1/4, or 1/8 of the lbiu_clk frequency (depending on LCCR[CLKDIV]) which is in turn 1x or 2x the csb_clk frequency (depending on RCWL[LBIUCM]). 1 2 Minimum Operating Frequency (MHz) 333 133 125 167 — — 25 — — — — — Maximum Operating Frequency (MHz) 800 400 200 333 133 400 66 400 200 200 200 400 22.1 System PLL Configuration The system PLL is controlled by the RCWL[SPMF] parameter. The system PLL VCO frequency depends on RCWL[DDRCM] and RCWL[LBCM]. Table 70 shows the multiplication factor encodings for the system PLL. NOTE If RCWL[DDRCM] and RCWL[LBCM] are both cleared, the system PLL VCO frequency = (CSB frequency) × (System PLL VCO Divider). If either RCWL[DDRCM] or RCWL[LBCM] are set, the system PLL VCO frequency = 2 × (CSB frequency) × (System PLL VCO Divider). The VCO divider needs to be set properly so that the System PLL VCO frequency is in the range of 400–800 MHz.

Generally, the value obtained on a single layer board is appropriate for a tightly packed printed circuit board. The value obtained on the board with the internal planes is usually appropriate if the board has low power dissipation and the components are well separated. Test cases have demonstrated that errors of a factor of two (in the quantity TJ – TA) are possible. 23.2.2 Estimation of Junction Temperature with Junction-to-Board Thermal Resistance NOTE The heat sink cannot be mounted on the package. MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 114 Freescale Semiconductor Thermal The thermal performance of a device cannot be adequately predicted from the junction to ambient thermal resistance. The thermal performance of any component is strongly dependent on the power dissipation of surrounding components. In addition, the ambient temperature varies widely within the application. For many natural convection and especially closed box applications, the board temperature at the perimeter (edge) of the package is approximately the same as the local air temperature near the device. Specifying the local ambient conditions explicitly as the board temperature provides a more precise description of the local ambient conditions that determine the temperature of the device. At a known board temperature, the junction temperature is estimated using the following equation: TJ = TA + (RθJB × PD) where: TA = ambient temperature for the package (°C) RθJB = junction to board thermal resistance (°C/W) per JESD51-8 PD = power dissipation in the package (W) When the heat loss from the package case to the air can be ignored, acceptable predictions of junction temperature can be made. The application board should be similar to the thermal test condition: the component is soldered to a board with internal planes. 23.2.3 Experimental Determination of Junction Temperature NOTE The heat sink cannot be mounted on the package. To determine the junction temperature of the device in the application after prototypes are available, use the thermal characterization parameter (ΨJT) to determine the junction temperature and a measure of the temperature at the top center of the package case using the following equation: TJ = TT + (ΨJT × PD) where: TJ = junction temperature (°C) TT = thermocouple temperature on top of package (°C) ΨJT = junction to ambient thermal resistance (°C/W) PD = power dissipation in the package (W) The thermal characterization parameter is measured per the JESD51-2 specification using a 40 gauge type T thermocouple epoxied to the top center of the package case. The thermocouple should be positioned so that the thermocouple junction rests on the package. A small amount of epoxy is placed over the thermocouple junction and over about 1 mm of wire extending from the junction. The thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. 23.2.4 Heat Sinks and Junction-to-Case Thermal Resistance For the power values the device is expected to operate at, it is anticipated that a heat sink will be required. A preliminary estimate of heat sink performance can be obtained from the following first first-cut MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 115 Thermal approach. The thermal resistance is expressed as the sum of a junction to case thermal resistance and a case-to-ambient thermal resistance: RθJA = RθJC + RθCA where: RθJA = junction to ambient thermal resistance (°C/W) RθJC = junction to case thermal resistance (°C/W) RθCA = case to ambient thermal resistance (°C/W) RθJC is device-related and cannot be influenced by the user. The user controls the thermal environment to change the case to ambient thermal resistance, RθCA. For instance, the user can change the size of the heat sink, the air flow around the device, the interface material, the mounting arrangement on printed circuit board, or change the thermal dissipation on the printed circuit board surrounding the device. This first-cut approach overestimates the heat sink size required, since heat flow through the board is not accounted for, which can be as much as one-third to one-half of the power generated in the package. Accurate thermal design requires thermal modeling of the application environment using computational fluid dynamics software which can model both the conduction cooling through the package and board and the convection cooling due to the air moving through the application. Simplified thermal models of the packages can be assembled using the junction-to-case and junction-to-board thermal resistances listed in the thermal resistance table. More detailed thermal models can be made available on request. The thermal performance of devices with heat sinks has been simulated with a few commercially available heat sinks. The heat sink choice is determined by the application environment (temperature, air flow, adjacent component power dissipation) and the physical space available. Because of the wide variety of application environments, a single standard heat sink applicable to all cannot be specified.

When heat sinks are attached, an interface material is required, preferably thermal grease and a spring clip. The spring clip should connect to the printed circuit board, either to the board itself, to hooks soldered to the board, or to a plastic stiffener. Avoid attachment forces that can lift the edge of the package or peel the package from the board. Such peeling forces reduce the solder joint lifetime of the package. The recommended maximum compressive force on the top of the package is 10 lb force (4.5 kg force). Any adhesive attachment should attach to painted or plastic surfaces, and its performance should be verified under the application requirements. 23.3.1 Experimental Determination of the Junction Temperature with a Heat Sink When a heat sink is used, the junction temperature is determined from a thermocouple inserted at the interface between the case of the package and the interface material. A clearance slot or hole is normally required in the heat sink. Minimize the size of the clearance to minimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. Because of the experimental difficulties with this technique, many engineers measure the heat sink temperature and then back calculate the case temperature using a separate measurement of the thermal resistance of the interface. From this case temperature, the junction temperature is determined from the junction to case thermal resistance. TJ = TC + (RθJC × PD) where: TJ = junction temperature (°C) TC = case temperature of the package (°C) MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 118 Freescale Semiconductor System Design Information RθJC = junction to case thermal resistance (°C/W) PD = power dissipation (W) 24 System Design Information This section provides electrical and thermal design recommendations for successful application of the MPC8378E. 24.1 PLL Power Supply Filtering Each of the PLLs listed above is provided with power through independent power supply pins. 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. There are a number of ways to reliably provide power to the PLLs, but the recommended solution is to provide five independent filter circuits as illustrated in Figure 68, one to each of the five 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 AV DD pin, which is on the periphery of package, without the inductance of vias. Figure 68 shows the PLL power supply filter circuit. 10 Ω VDD 2.2 µF 2.2 µF Low ESL Surface Mount Capacitors AVDD (or L2AVDD) GND Figure 68. PLL Power Supply Filter Circuit 24.2 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 device 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, OVDD, GVDD, and LVDD pins of the device. These decoupling capacitors should receive their power from separate VDD, OVDD, GVDD, LVDD, and GND power planes in the PCB, utilizing short traces to minimize inductance. Capacitors may be placed directly under the device using a standard escape pattern. Others may surround the part. MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 Freescale Semiconductor 119 System Design Information These capacitors should have a value of 0.01 or 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, 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). 24.3 Connection Recommendations To ensure reliable operation, it is highly recommended that unused inputs be connected to an appropriate signal level. Unused active low inputs should be tied to OVDD, GVDD, or LVDD as required. 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, GVDD, LVDD, OVDD, and GND pins of the device. 24.4 Output Buffer DC Impedance The device 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 69). 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. OVDD RN SW2 Data Pad SW1 RP OGND Figure 69. Driver Impedance Measurement MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 120 Freescale Semiconductor Ordering Information The value of this resistance and the strength of the driver’s current source can be found by making two measurements. First, the output voltage is measured while driving logic 1 without an external differential termination resistor. The measured voltage is V1 = Rsource × Isource. Second, the output voltage is measured while driving logic 1 with an external precision differential termination resistor of value R term. The measured voltage is V2 = (1/(1/R1 + 1/R2)) × Isource. Solving for the output impedance gives Rsource = Rterm × (V1/V2 – 1). The drive current is then Isource = V1/Rsource. Table 78 summarizes the signal impedance targets. The driver impedance are targeted at minimum VDD, nominal OVDD, 105°C. Table 78.

See Table 2, Tj = 105° C. 24.5 Configuration Pin Muxing The device 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 PORESET deasserts, at which time the input receiver is disabled and the I/O circuit takes on its normal function. Careful board layout with stubless connections to these pull-up/pull-down resistors coupled with the large value of the pull-up/pull-down resistor should minimize the disruption of signal quality or speed for output pins thus configured. 24.6 Pull-Up Resistor Requirements The device requires high resistance pull-up resistors (10 kΩ is recommended) on open drain type pins including I2C pins, Ethernet Management MDIO pin and IPIC interrupt pins.
