1.10 Serial Peripheral Interface (SPI)
The serial peripheral interface (SPI) allows the MPC8313E to exchange data between other PowerQUICC
family chips, Ethernet PHYs for configuration, and peripheral devices such as EEPROMs, real-time
clocks, A/D converters, and ISDN devices.
The SPI is a full-duplex, synchronous, character-oriented channel that supports a four-wire interface
(receive, transmit, clock, and slave select). The SPI block consists of transmitter and receiver sections, an
independent baud-rate generator, and a control unit.
1.11 DMA Controller, Dual I2C, DUART, Local Bus Controller, and
Timers
The MPC8313E provides an integrated four-channel DMA controller with the following features:
• Allows chaining (both extended and direct) through local memory-mapped chain descriptors
(accessible by local masters)
• Supports misaligned transfers
There are two I2C controllers. These synchronous, multi-master buses can be connected to additional
devices for expansion and system development.
The DUART supports full-duplex operation and is compatible with the PC16450 and PC16550
programming models. The 16-byte FIFOs are supported for both the transmitter and the receiver.
The MPC8313E local bus controller (LBC) port allows connections with a wide variety of external DSPs
and ASICs. Three separate state machines share the same external pins and can be programmed separately
to access different types of devices. The general-purpose chip select machine (GPCM) controls accesses
to asynchronous devices using a simple handshake protocol. The three user programmable machines
(UPMs) can be programmed to interface to synchronous devices or custom ASIC interfaces. Each chip
select can be configured so that the associated chip interface can be controlled by the GPCM or UPM
controller. The FCM provides a glueless interface to parallel-bus NAND Flash E2PROM devices. The
FCM contains three basic configuration register groups—BRn, ORn, and FMR. Both may exist in the
same system. The local bus can operate at up to 66 MHz.
The MPC8313E system timers include the following features: periodic interrupt timer, real time clock,
software watchdog timer, and two general-purpose timer blocks.

2.2 Power Sequencing
The MPC8313E does not require the core supply voltage (VDD and VDDC) and I/O supply voltages
(GVDD, LVDD, and NVDD) to be applied in any particular order. Note that during power ramp-up, before
the power supplies are stable and if the I/O voltages are supplied before the core voltage, there might be a
period of time that all input and output pins are actively driven and cause contention and excessive current.
In order to avoid actively driving the I/O pins and to eliminate excessive current draw, apply the core
voltage (VDD and VDDC) before the I/O voltage (GVDD, LVDD, and NVDD) and assert PORESET before
the power supplies fully ramp up. In the case where the core voltage is applied first, the core voltage supply
must rise to 90% of its nominal value before the I/O supplies reach 0.7 V; see Figure 3. Once both the
power supplies (I/O voltage and core voltage) are stable, wait for a minimum of 32 clock cycles before
negating PORESET.
Note that there is no specific power down sequence requirement for the MPC8313E. I/O voltage supplies
(GVDD, LVDD, and NVDD) do not have any ordering requirements with respect to one another.

Notes:
1. tPCI_SYNC_IN is the clock period of the input clock applied to PCI_SYNC_IN. When the device is In PCI host mode the
primary clock is applied to the SYS_CLK_IN input, and PCI_SYNC_IN period depends on the value of CFG_CLKIN_DIV.
2. tSYS_CLK_IN is the clock period of the input clock applied to SYS_CLK_IN. It is only valid when the device is in PCI host mode.
3. POR configuration signals consists of CFG_RESET_SOURCE[0:2] and CFG_CLKIN_DIV.

Notes:
1. tCISKEW represents the total amount of skew consumed by the controller between MDQS[n] and any corresponding bit that
is captured with MDQS[n]. This should be subtracted from the total timing budget.
2. The amount of skew that can be tolerated from MDQS to a corresponding MDQ signal is called tDISKEW. This can be
determined by the f ollowing equation: tDISKEW = ± (T/4 – abs(tCISKEW)) where T is the clock period and abs(tCISKEW) is the

Note:
1. Note that, in general, the clock ref erence symbol representation f or this section is based on the symbols RGT to represent
RGMII and RTBI timing. F or example, the subscript of tRGT represents the RTBI (T) receive (RX) clock. Note also that the
notation f o r 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 requires clocks to be routed such that an additional trace delay of greater than 1.5 ns is
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 transitioning 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.
5. Duty cycle reference is LVDDA/2 or LVDDB/2.
6. This symbol is used to represent the external GTX_CLK125 and does not follow the original symbol naming convention.
7. The frequency of RX_CLK should not exceed the GTX_CLK1 25 by more than 300 ppm

8.3 SGMII Interface Electrical Characteristics
Each SGMII port features a 4-wire AC-coupled serial link from the dedicated SerDes interface of
MPC8313E as shown in Figure 15, where CTX is the external (on board) AC-coupled capacitor. Each
output pin of the SerDes transmitter dif ferential pair features a 50-output impedance. Each input of the
SerDes receiver differential pair features 50- on-die termination to XCOREVSS. The reference circuit
of the SerDes transmitter and receiver is shown in Figure 33.
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 22.5, “Connection Recommendations,” as long as such termination does not violate
the desired POR configuration requirement on these pins, if applicable.
When operating in SGMII mode, the TSEC_GTX_CLK125 clock is not required for this port. Instead, the
SerDes reference clock is required on SD_REF_CLK and SD_REF_CLK pins.
8.3.1 DC Requirements for SGMII SD_REF_CLK and SD_REF_CLK

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).

9 High-Speed Serial Interfaces (HSSI)
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.
9.1 Signal Terms Definition
The SerDes utilizes differential sign aling to transfer data across the serial link. This section defines terms
used in the description and specification of differential signals.
Figure 22 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 (TXn and TXn) or a receiver input
(RXn and RXn). 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 TXn, TXn, RXn, and RXn 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, VOD, is defined as the difference of
the two complimentary output voltages: VTXn – VTXn. The VOD value can be either positive or
negative.
3. 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: VRXn – VRXn. 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 dif ferential 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 VTX-DIFFp-p = 2 |VOD|.
6. Differential waveform
The differential waveform is constructed by subtracting the inverting signal (TXn, for example)
from the non-inverting signal (TXn, for example) within a differential pair . There is only one signal
trace curve in a diff erential waveform. The voltage represented in the dif ferential waveform is not
referenced to ground. Refer to Figure 22 as an example for differential waveform.

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 =
(VTXn+V
TXn)/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’s also referred as the DC
offset in some occasion.
Figure 22. 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 2.5 and 2.0 V. 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 sig nal. In this example, since the
differential signaling environment is fully symme trical, the transmitter output’s dif ferential swing (VOD)
has the same amplitude as each signal’s single-ended swing. The dif ferential output signal ranges between
500 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.
9.2 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 input is SD_REF_CLK and SD_REF_CLK
for SGMII interface.
The following sections describe the SerDes reference clock requirements and some application
information.

— The SD_REF_CLK and SD_REF_CLK are internally AC-coupled differential inputs as shown
in Figure 23. Each differential clock input (SD_REF_CLK or SD_REF_CLK) has a 50-
termination to 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 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 to 16 mA (0–0.8 V), such that each phase of the dif ferential
input has a single-ended swing from 0 V to 800 mV with the common mode voltage at 400 mV.
— If the device driving the SD_REF_CLK and SD_REF_CLK inputs cannot drive 50 to
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.
Figure 23. Receiver of Ser De s Referen c e Clo cks
9.2.2 DC Level Requirement for SerDes Reference Clocks
The DC level requirement for the MPC8313E 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 and 1600 mV differential
peak-to-peak (or between 200 and 800 mV differential peak). In other word s, 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 9.2.1, “SerDes Reference Clock
Receiver Characteristics,” the maximum average current requirements sets the requirement for
average voltage (common mode voltage) to be between 100 and 400 mV. Figure 24 shows the
SerDes reference clock input requirement for the 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
XCOREVSS. Each signal wire of the differential inputs is allowed to swing below and above
the command mode voltage (XCOREVSS). Figure 25 shows the SerDes reference clock input
requirement for AC-coupled connection scheme.
• Single-ended mode
— The reference clock can also be single-ended. The SD_REF_CLK input amplitude
(single-ended swing) must be between 400 and 800 mV peak-to-peak (from Vmin to Vmax) with
SD_REF_CLK either left unconnected or tied to ground.
— The SD_REF_CLK input average voltage must be between 200 and 400 mV. Figure 26 shows
the SerDes reference clock input requirement for the 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 (SD_REF_CLK) through the same source impedance as
the clock input (SD_REF_CLK) in use.

9.2.3 Interfacing With Other Differential Signaling Levels
• With on-chip termination to 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 outputs can produce a signal with too large of an amplitude and may need to be
DC-biased at the clock driver output first, then followed with series attenuation resistor to reduce
the amplitude, in addition to AC coupling.
NOTE
Figure 27 through Figure 30 are for conceptual reference only. Due to the
fact that the clock driver chip's internal structure, output impedance, and
termination requirements are different between various clock driver chip
manufacturers, it is possible that the clock circuit reference designs
provided by clock driver chip vendors are different from what is shown in
the figures. They might also vary from one vendor to the other. Therefore,
Freescale can neither provide the optimal clock driver reference circuits, nor
guarantee the correctness of the following clock driver connection reference
circuits. It is recommended that the system designer contact the selected
clock driver chip vendor for the optimal reference circuits for the
MPC8313E SerDes reference clock receiver requirement provided in this
document.

This figure shows the SerDes reference clock connection reference circuits for HCSL type clock driver. It
assumes that the DC levels of the clock driver chip is compatible with MPC8313E SerDes reference clock
input’s DC requirement.
Figure 27. DC-Coupled Differential Connection with HCSL Clock Driver (Reference Only)
This figure 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 MPC8313E SerDes reference clock
input’s allowed range (100 to 400 mV), the AC-coupled connection scheme must be used. It assumes the
LVDS output driver features a 50-termination resistor. It also assumes that the LVDS transmitter
establishes its own common mode level without relying on the receiver or other external component.
Figure 28. AC-Coupled Differential Connection with LVDS Clock Driver (Reference Only)
This figure 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

outputs prior to AC coupling. Its value could be ranged from 140to 240 depending on the clock driver
vendor’s requirement. R2 is used together with the SerDes reference clock receiver’s 50- termination
resistor to attenuate the LVPECL output’s differential peak level such that it meets the MPC8313E
SerDes3 reference clock’ s dif ferential input amplitude requirement (between 200 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
Consult with the clock driver chip manufacturer to verify whether this connection scheme is compatible
with a particular clock driver chip.

9.2.4 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 to match the
transmission line and reduce reflections which are a source of noise to the system.
This table describes some AC parameters for SGMII protocol.

centered on the differential zero crossing. See Figure 31.
4. Matching applies to rising edge rate f or SDn_REF_CLK and falling edge rate for SDn_REF_CLK. It is measured using a
200 mV window centered on the median cross point, where SDn_REF_CLK rising meets SDn_REF_CLK f alling. 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 32.

Notes:
1. All outputs are measured from the midpoint voltage of the falling/rising edge of tTCLK to the midpoint of the signal in question.
The output timings are measured at the pins. All output timings assume a purely resistive 50-load (see Figure 34).
Time-of-flight delays must be added for trace lengths, vias, and connectors in the system.
2. The symbols used for timing specifications follow the pattern of t(first two letters of funct ional block)(signal)(state)(reference)( s tate) for
inputs and t(first two letters of functional bloc k)(reference) (state)(signal)(state) for outputs. For example, tJTDVKH symbolizes JTA G device
timing (JT) with respect to the time data input signals (D) reaching the valid state (V) relative to the tJTG clock ref erence (K)
going to the high (H) state or setup time. Also, tJTDXKH symbolizes JTAG timing (JT) with respect to the time data input
signals (D) went in valid (X) relativ e to the tJTG clock ref erence (K) going to the high (H) state. Note that, in general, the clock
ref erence symbol representation is based on three letters representing the clock of a particular functional. For rise and fall
times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
3. TRST is an asynchronous level sensitive signal. The setup time is for test purposes only.
4. Non-JTAG signal input timing with respect to tTCLK.
5. Non-JTA G signal output timing with respect to tTCLK.
6. Guaranteed by design and characterization.

The primary clock source for the MPC8313E can be one of two inputs, SYS_CLK_IN 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, SYS_CLK_IN is its primary input clock. SYS_CLK_IN 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 SYS_CLK_IN or SYS_CLK_IN/2 is driven out
on the PCI_SYNC_OUT signal. The OCCR[PCICOE n] parameters select whether the PCI_SYNC_OUT
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 SYS_CLK_IN signal should be tied to VSS.
As shown in Figure 57, 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 (lbc_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 SYS_CLK_IN 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 MPC8313E PowerQUICC II Pro Integrated Processor Family
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 lbc_clk frequency is determined by the following equation:
lbc_clk = csb_clk × (1 + RCWL[LBCM])
Note that lbc_clk is not the external local bus frequency; lbc_clk passes through the a LBC clock divider
to create the external local bus clock outputs (LCLK[0:1]). The LBC clock divider ratio is controlled by
LCRR[CLKDIV].
In addition, 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 63 specifies which units have a configurable clock
frequency.

Note:
1. The SYS_CLK_IN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen
such that the resulting csb_clk, MCK, LCLK[0:1], and core_clk frequen cies do not exceed their
respective maximum or minimum operating frequencies. The value of SCCR[ENCCM] and
SCCR[USBDRCM] must be programmed such that the maximum internal operating frequency of

21.2 Thermal Management Information
For the following sections, PD = (VDD IDD) + PI/O, where PI/O is the power dissipation of the I/O drivers.
21.2.1 Estimation of Junction Temperature with Junction-to-Ambient
Thermal Resistance
An estimation of the chip junction temperature, TJ, can be obtained from the equation:
TJ = TA + (R
JA PD)
where: TJ = junction temperature (C)
TA = ambient temperature for the package (C)
R
JA = junction-to-ambient thermal resistance (C/W)
PD = power dissipation in the package (W)
The junction-to-ambient thermal resistance is an industry standard value that provides a quick and easy
estimation of thermal performance. As a general statement, 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.
21.2.2 Estimation of Junction Temperature with Junction-to-Board
Thermal Resistance
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

Note:
1. J unction temperature is a function of die size, on-chip pow er dissipation, package thermal resistance, mounting site (board)
temperature, ambient temperature , airflow , pow er dissipation of other components on the board, and board thermal resistance.
2. Per JEDEC JESD51-2 with the single layer board horizontal. Board meets JESD51-9 specification.
3. Per JEDEC JESD51-6 with the board horizontal.
4. Thermal resistance between the die and the pri nted-circuit board per JEDEC JESD51-8. Board temperature is measured on
the top surface of the board near the package.
5. Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method
1012.1).
6. Thermal characterization parameter indicating the temperature difference between package top and the junction temperature

(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 = TB + (R
JB PD)
where: TJ = junction temperature (C)
TB = board temperature at the package perimeter (C)
R
JB = 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.
21.2.3 Experimental Determination of Junction Temperature
To determine the junction temperature of the device in the application after prototypes are available, the
thermal characterization parameter (
JT) can be used to determine the junction temperature with a
measurement of the temperature at the top center of the package case using the following equation:
TJ = TT + (
JT PD)
where: TJ = junction temperature (C)
TT = thermocouple temperature on top of package (C)
JT = thermal characterization parameter (C/W)
PD = power dissipation in the package (W)
The thermal characterization parameter is measured per JESD51-2 specificatio n 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.
21.2.4 Heat Sinks and Junction-to-Case Thermal Resistance
In some application environments, a heat sink is required to provide the necessary thermal management of
the device. When a heat sink is used, the thermal resistance is expressed as the sum of a junction to case
thermal resistance and a case to ambient thermal resistance:
R
JA = R
JC + R
CA
where: R
JA = junction-to-ambient thermal resistance (C/W)
R
JC = junction-to-case thermal resistance (C/W)
R
CA = case-to- ambient thermal resistance (C/W)
MPC8313E PowerQUICC II Pro Processor Hardware Specifications , Rev. 4
Freescale Semiconductor 85
R
JC is device related and cannot be influenced by the user. The user controls the thermal environment to
change the case-to-ambient thermal resistance, R
CA. For instance, the user can change the size of the heat
sink, the airflow around the device, the interface material, the mounting arrangement on the printed-circuit
board, or change the thermal dissipation on the printed-circuit board surrounding the device.
To illustrate the thermal performance of the devices with heat sinks, the thermal performance has been
simulated with a few commercially available heat sinks. The heat sink choice is determined by the
application environment (temperature, airflow, adjacent component power dissipation) and the physical
space available. Because there is not a standard application environment, a standard heat sink is not
required.
Accurate thermal design requires thermal modeling of the application environment using computational
fluid dynamics software which can model both the conduction cooling and the convection cooling of 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 Table 70. More detailed thermal
models can be made available on request.

21.3 Heat Sink Attachment
When attaching heat sinks to these devices, an interface material is required. The best method is to use
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 which would
lift the edge of the package or peel the package from the board. Such peeling forces reduce the s older joint
lifetime of the package. Recommended maximum force on the top of the package is 10 lb (4.5 kg) force.
If an adhesive attachment is planned, the adhesive should be intended for attachment to painted or plastic
surfaces and its performance verified under the application requirements.
21.3.1 Experimental Determination of the Junction Temperature with a
Heat Sink
When heat sink is used, the junction temperature is determined from a thermocouple inserted at the
interface between the case of the package and the interface material. A clearance slot or hole is normally
required in the heat sink. Minimizing the size of the clearance is important to minimize the change in
thermal performance caused by removing part of the thermal interface to the heat sink. Because of the
experimental difficulties with this technique, many engineers measure the heat sink temperature and then
back calculate the case temperature using a separate measurement of the thermal resistance of the
interface. From this case temperature, the junction temperature is determined from the junction to case
thermal resistance.

22 System Design Information
This section provides electrical and thermal design recommendations for successful application of the
MPC8313E SYS_CLK_IN
22.1 System Clocking
The MPC8313E includes three PLLs.
1. The platform PLL (AVDD2) generates the platform clock from the externally supplied
SYS_CLK_IN input in PCI host mode or SYS_CLK_IN/PCI_SYNC_IN in PCI agent mode. The
frequency ratio between the platform and SYS_CLK_IN is selected using the platform PLL ratio
configuration bits as described in Section 20.1, “System PLL Configuration.”
2. The e300 core PLL (AVDD1) generates the core clock as a slave to the platform clock. The
frequency ratio between the e300 core clock and the platform clock is selected using the e300
PLL ratio configuration bits as described in Section 20.2, “Core PLL Configuration.”
3. There is a PLL for the SerDes block.
MPC8313E PowerQUICC II Pro Processor Hardware Specifications , Rev. 4
88 Freescale Semiconductor
22.2 PLL Power Supply Filtering
Each of the PLLs listed above is provided with power through independent power supply pins (AVDD1,
AVDD2, and SDAVDD, respectively). The AVDD level should always be equivalent to VDD, and preferably
these voltages are 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 as illustrated in Figure 58, 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 AVDD
pin, which is on the periphery of package, without the inductance of vias.
This figure shows the PLL power supply filter circuits.
Figure 58. PLL Power Supply Filter Circuit
The SDAVDD signal 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 like the one shown in Figure 59.
For maximum effectiveness, the filter circuit should be placed as closely as possible to the SDAVDD ball
to ensure it filters out as much noise as possible. The ground connection should be near the SDAVDD ball.
The 0.003-µF capacitor is closest to the ball, followed by the two 2.2-µF capacitors, and finally the 1-
resistor to the board supply plane. The capacitors are connected from traces from SDAVDD to the ground
plane. Use ceramic chip capacitors with the highest possible self-resonant frequency. All traces should be
kept short, wide, and direct.

• Output signals on the SerDes interface are fed from the XPADVDD power plane. Input signals and
sensitive transceiver analog circuits are on the XCOREVDD supply.
• Power: XPADVDD consumes less than 300 mW; XCOREVDD +SDAV
DD consumes less than
750 mW.
22.3 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 lar ge capacitive loads.
This noise must be prevented from reaching other components in the MPC8313E system, and the
MPC8313E 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, NVDD, GVDD, LVDD, LVDDA,
and LVDDB pin of the device. These decoupling capacitors should receive their power from separate VDD,
NVDD, GVDD, LVDD, LVDDA, LVDDB, and VSS 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.
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, NVDD, GVDD, LVDD, LVDDA, and LVDDB 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 to 330 µF (AVX TPS
tantalum or Sanyo OSCON). However , customers should work directly with their power regulator vendor
for best values and types of bulk capacitors.
22.4 SerDes Block Power Supply Decoupling Recommendations
The SerDes block requires a clean, tightly regulated source of power (XCOREVDD and XPADVDD) to
ensure low jitter on transmit and reliable recovery of data in the receiver. An appropriate decoupling
scheme is outlined below.
Only 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 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 (XCOREVDD and
XPADVDD) to the board ground plane on each side of the device. This should be done for all
SerDes supplies.
MPC8313E PowerQUICC II Pro Processor Hardware Specifications , Rev. 4
90 Freescale Semiconductor
• 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.
22.5 Connection Recommendations
To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal
level. Unused active low inputs should be tied to NVDD, GVDD, LVDD, LVDDA, or LVDDB as required.
Unused active high inputs should be connected to VSS. All NC (no-connect) signals must remain
unconnected.
Power and ground connections must be made to all external VDD, NVDD, GVDD, LVDD, LVDDA, LVDDB,
and VSS pins of the device.
22.6 Output Buffer DC Impedance
The MPC8313E 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 NVDD
or VSS. Then, the value of each resistor is varied until the pad voltage is NVDD/2 (see Figure 60). 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
NVDD/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.
Figure 60. Driver Impedance Measurement
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 exte rnal dif ferential
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 Rterm. The
measured voltage is V2=(1/(1/R
1+1/R
2)) Isource. Solving for the output impedance gives Rsource =
Rterm (V1/V2– 1). The drive current is then Isource =V
1/Rsource.

This table summarizes the signal impedance tar gets. The driver impedance are tar geted at minimum VDD,

22.7 Configuration Pin Muxing
The MPC8313E 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 k 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 lar ge value of the pull-up/pull-down resistor should
minimize the disruption of signal quality or speed for output pins thus configured.
22.8 Pull-Up Resistor Requirements
The MPC8313E requires high resistance pull-up resistors (10 k is recommended) on open drain type pins
including I2C, and IPIC (integrated programmable interrupt controller).
Correct operation of the JTAG interface requires configuration of a group of system control pins as
demonstrated in Figure 61. Care must be taken to ensure that these pins are maintained at a valid deasserted
state under normal operating conditions because most have asynchronous behavior and spurious assertion,
which give unpredictable results.
Refer to the PCI 2.2 Specification, for all pull-ups required for PCI.
22.9 JTAG Configuration Signals
Boundary scan testing is enabled through the JTAG interface signals. The TRST signal is optional in
IEEE 1149.1, but is provided on any Freescale devices that are built on Power Architecture technology.
The device requires TRST to be asserted during reset conditions to ensure the JTAG boundary logic does
not interfere with normal chip operation. While it is possible to force the TAP controller to the reset state
using only the TCK and TMS signals, systems generally assert TRST during power -on reset. Because the
JTAG interface is also used for accessing the common on-chip processor (COP) function, simply tying
TRST to PORESET is not practical.

The COP function of these processors allows a remote computer system (typically, a PC with dedicated
hardware and debugging software) to access and control the internal operations of the processor . The COP
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 TRST without causing
PORESET. 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 61 allows the COP to independently assert HRESET or TRST, while
ensuring that the target can drive HRESET as well. If the JTAG interface and COP header are not used,
TRST should be tied to PORESET so that it is asserted when the system reset signal (PORESET) is
asserted.
The COP header shown in Figure 61 adds many benefits—breakpoints, watchpoints, register and memory
examination/modification, and other standard debugger features are possible through this interface—and
can be as inexpensive as an unpopulated footprint for a header to be added when needed.
The COP interface has a standard header for connection to the target system, based on the 0.025"
square-post, 0.100" centered header assembly (often called a Berg header).
There is no standardized way to number the COP header shown in Figure 61; 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 61 is common to all known emulators.
