Overview
The MPC8323E incorporates the e300c2 (MPC603e-based) core built on Power Architecture®
technology, which includes 16 Kbytes of L1 instruction and data caches, dual integer units, and on-chip
memory management units (MMUs). The e300c2 core does not contain a floating point unit (FPU). The
MPC8323E also includes a 32-bit PCI controller, four DMA channels, a security engine, and a 32-bit
DDR1/DDR2 memory controller.
A new communications complex based on QUICC Engine technology forms the heart of the networking
capability of the MPC8323E. The QUICC Engine block contains several peripheral controllers and a
32-bit RISC controller. Protocol support is provided by the main workhorses of the device—the unified
communication controllers (UCCs). Note that the MPC8321 and MPC8321E do not support UTOPIA. A
block diagram of the MPC8323E is shown in Figure 1.

Power Sequencing
The device does not require the core supply voltage (VDD) and IO supply voltages (GVDD and OVDD) 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) before the I/O
voltage (GVDD and OVDD) 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 device. I/O voltage supplies
(GVDD and OVDD) do not have any ordering requirements with respect to one another.

Notes:
1. Caution: The system, core, security, and QUICC Engine block must not exceed their respective maximum or minimum
operating frequencies.
2. Rise and fall times for CLKIN/PCI_CLK are measured at 0.4 and 2.7 V.
3. Timing is guaranteed by design and characterization.
4. This represents the total input jitter—short term and long term—and is guaranteed by design.
5. The CLKIN/PCI_CLK 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 CLKIN drivers with the specified jitter.

Notes:
1. tPCI_SYNC_IN is the clock period of the input clock applied to PCI_SYNC_IN. When the MPC8323E is In PCI host mode the
primary clock is applied to the CLKIN input, and PCI_SYNC_IN period depends on the value of CFG_CLKIN_DIV. See the
MPC8323E PowerQUICC II Pro Integrated Communications Processor Reference Manual for more details.
2. tCLKIN is the clock period of the input clock applied to CLKIN. It is only valid when the MPC8323E is in PCI host mode. See
the MPC8323E PowerQUICC II Pro Integrated Communications Processor Reference Manual for more details.
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 following equation: tDISKEW = ±(T/4 – abs(tCISKEW)) where T is the clock period and abs(tCISKEW) is the
absolute value of tCISKEW.

Notes:
1. The symbols used for timing specifications 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. Output hold time can be read as DDR timing
(DD) from the rising or falling edge of the reference clock (KH or KL) until the output went invalid (AX or DX). 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/MDM/MDQS. For the ADDR/CMD
setup and hold specifications, it is assumed that the Clock Control register is set to adjust the memory clocks by 1/2 applied
cycle.
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 is typically 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 MPC8323E PowerQUICC II Pro Integrated Communications 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), 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.

Note:
1. The symbols used for timing specifications follow the pattern of t(first three 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, tRMRDVKH symbolizes RMII
receive timing (RMR) with respect to the time data input signals (D) reach the valid state (V) relative to the tRMX clock
reference (K) going to the high (H) state or setup time. Also, tRMRDXKL symbolizes RMII receive timing (RMR) with respect to
the time data input signals (D) went invalid (X) relative to the tRMX clock reference (K) going to the low (L) state or hold time.
Note that, in general, the clock reference symbol representation is based on three letters representing the clock of a particular
functional. For example, the subscript of tRMX represents the RMII (RM) reference (X) clock. For rise and fall times, the latter
convention is used with the appropriate letter: R (rise) or F (fall).

Notes:
1. The symbols used for timing specifications 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, tLBIXKH1 symbolizes local bus
timing (LB) for the input (I) to go invalid (X) with respect to the time the tLBK clock reference (K) goes high (H), in this case for
clock one(1).
2. All timings are in reference to falling edge of LCLK0 (for all outputs and for LGTA and LUPWAIT inputs) or rising edge of
LCLK0 (for all other inputs).
3. All signals are measured from OVDD/2 of the rising/falling edge of LCLK0 to 0.4 × OVDD of the signal in question for 3.3-V
signaling levels.
4. Input timings are measured at the pin.
5. tLBOTOT1 should be used when RCWH[LALE] is not set and the load on LALE output pin is at least 10 pF less than the load
on LAD output pins.
6. tLBOTOT2 should be used when RCWH[LALE] is set and the load on LALE output pin is at least 10 pF less than the load on
LAD output pins.
7. tLBOTOT3 should be used when RCWH[LALE] is set and the load on LALE output pin equals to the load on LAD output pins.
8. For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered
through the component pin is less than or equal to the leakage current specification.

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-Ω load (see Figure 14).
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 functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tJTDVKH symbolizes JTAG device
timing (JT) with respect to the time data input signals (D) reaching the valid state (V) relative to the tJTG clock reference (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 invalid (X) relative to the tJTG clock reference (K) going to the high (H) state. Note that, in general, the clock reference
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-JTAG signal output timing with respect to tTCLK.
6. Guaranteed by design and characterization.

Notes:

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. MPC8323E provides a hold time of at least 300 ns for the SDA signal (referred to the VIH(min) of the SCL signal) to bridge
the undefined region of the falling edge of SCL.
3. The maximum tI2DVKH has only to be met if the device does not stretch the LOW period (tI2CL) of the SCL signal.

on whether the device is configured in PCI host or PCI agent mode, respectively.
MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4

Freescale Semiconductor
Clocking
22.1
Clocking in PCI Host Mode
When the MPC8323E is configured as a PCI host device (RCWH[PCIHOST] = 1), CLKIN is its primary
input clock. CLKIN feeds the PCI clock divider (÷2) and the PCI_SYNC_OUT and PCI_CLK_OUT
multiplexors. The CFG_CLKIN_DIV configuration input selects whether CLKIN or CLKIN/2 is driven
out on the PCI_SYNC_OUT signal.
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.
22.1.1
PCI Clock Outputs (PCI_CLK_OUT[0:2])
When the MPC8323E is configured as a PCI host, it provides three separate clock output signals,
PCI_CLK_OUT[0:2], for external PCI agents.
When the device comes out of reset, the PCI clock outputs are disabled and are actively driven to a steady
low state. Each of the individual clock outputs can be enabled (enable toggling of the clock) by setting its
corresponding OCCR[PCICOEn] bit. All output clocks are phase-aligned to each other.
22.2
Clocking in PCI Agent Mode
When the MPC8323E is configured as a PCI agent device, PCI_CLK is the primary input clock. In agent
mode, the CLKIN signal should be tied to GND, and the clock output signals, PCI_CLK_OUTn and
PCI_SYNC_OUT, are not used.
22.3
System Clock Domains
As shown in Figure 43, the primary clock input (frequency) is multiplied up by the system phase-locked
loop (PLL) and the clock unit to create three major clock domains:
• The coherent system bus clock (csb_clk)
• The QUICC Engine clock (ce_clk)
• The internal clock for the DDR controller (ddr_clk)
• The internal clock for the local bus controller (lb_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 e300c2 core. A second PLL inside the core multiplies up the
csb_clk frequency to create the internal clock for the 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 the “Reset Configuration” section
in the MPC8323E PowerQUICC II Pro Communications Processor Reference Manual for more
information.
MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4
Freescale Semiconductor
65
Clocking
The ce_clk frequency is determined by the QUICC Engine PLL multiplication factor (RCWL[CEPMF)
and the QUICC Engine PLL division factor (RCWL[CEPDF]) according to the following equation:
When CLKIN is the primary input clock,
ce_clk = (primary clock input × CEPMF) ÷ (1 + CEPDF)
When PCI_CLK is the primary input clock,
ce_clk = [primary clock input × CEPMF × (1 + ~CFG_CLKIN_DIV)] ÷ (1 + CEPDF)
See the “QUICC Engine PLL Multiplication Factor” section and the “QUICC Engine PLL Division
Factor” section in the MPC8323E PowerQUICC II Pro Communications Processor Reference Manual for
more information.
The DDR SDRAM memory controller operates with a frequency equal to twice the frequency of csb_clk.
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 local bus memory controller operates with a frequency equal to the frequency of csb_clk. Note that
lbc_clk is not the external local bus frequency; lbc_clk passes through the LBC clock divider to create the
external local bus clock outputs (LSYNC_OUT and LCLK[0:2]). The LBC clock divider ratio is
controlled by LCRR[CLKDIV]. See the “LBC Bus Clock and Clock Ratios” section in the MPC8323E
PowerQUICC II Pro Communications Processor Reference Manual for more information.
In addition, some of the internal units may be required to be shut off or operate at lower frequency than
the csb_clk frequency. These units have a default clock ratio that can be configured by a memory mapped
register after the device comes out of reset. Table 56 specifies which units have a configurable clock
frequency. Refer to the “System Clock Control Register (SCCR)” section in the MPC8323E PowerQUICC
II Pro Communications Processor Reference Manual for a detailed description.

The CLKIN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen such that the resulting csb_clk, MCLK,
LCLK[0:2], and core_clk frequencies do not exceed their respective maximum or minimum operating frequencies.
2
The DDR1/DDR2 data rate is 2× the DDR1/DDR2 memory bus frequency.
3
The local bus frequency is 1/2, 1/4, or 1/8 of the lb_clk frequency (depending on LCRR[CLKDIV]) which is in turn 1× or 2× the
csb_clk frequency (depending on RCWL[LBCM]).
22.4
System PLL Configuration
The system PLL is controlled by the RCWL[SPMF] parameter. Table 58 shows the multiplication factor
encodings for the system PLL.
NOTE
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 300–600 MHz.

NOTE
The VCO divider (RCWL[CEVCOD]) must be set properly so that the
QUICC Engine VCO frequency is in the range of 300–600 MHz. The
QUICC Engine frequency is not restricted by the CSB and core frequencies.
The CSB, core, and QUICC Engine frequencies should be selected
according to the performance requirements.
The QUICC Engine VCO frequency is derived from the following
equations:
ce_clk = (primary clock input × CEPMF) ÷ (1 + CEPDF)
QUICC Engine VCO Frequency = ce_clk × VCO divider × (1 + CEPDF)

Suggested PLL Configurations
To simplify the PLL configurations, the MPC8323E might be separated into two clock domains. The first
domain contain the CSB PLL and the core PLL. The core PLL is connected serially to the CSB PLL, and
has the csb_clk as its input clock. The second clock domain has the QUICC Engine PLL. The clock
domains are independent, and each of their PLLs are configured separately. Both of the domains has one
common input clock. Table 63 shows suggested PLL configurations for 33, 25, and 66 MHz input clocks.

Notes:
1. Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site (board)
temperature, ambient temperature, air flow, power 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 printed-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
per JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is written as Psi-JT.
23.2
Thermal Management Information
For the following sections, PD = (VDD × IDD) + PI/O, where PI/O is the power dissipation of the I/O drivers.
23.2.1
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 + (RθJA × PD)
where:
TJ = junction temperature (°C)
TA = ambient temperature for the package (°C)
RθJA = 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.
23.2.2
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
MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4
72
Freescale Semiconductor
Thermal
(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 + (RθJB × PD)
where:
TJ = junction temperature (°C)
TB = board temperature at the package perimeter (°C)
RθJB = junction-to-board thermal resistance (°C/W) per JESD51-8
PD = power dissipation in 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
To determine the junction temperature of the device in the application after prototypes are available, the
thermal characterization parameter (ΨJT) 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 + (ΨJT × PD)
where:
TJ = junction temperature (°C)
TT = thermocouple temperature on top of package (°C)
ΨJT = thermal characterization parameter (°C/W)
PD = power dissipation in package (W)
The thermal characterization parameter is measured per 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
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:
RθJA = RθJC + RθCA
MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4
Freescale Semiconductor
73
Thermal
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.
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, air flow, 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 the thermal resistance table. More
detailed thermal models can be made available on request.

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 solder 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.
23.3.1
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.

where:

24 System Design Information
This section provides electrical and thermal design recommendations for successful application of the
MPC8323E.
24.1
System Clocking
The MPC8323E includes three PLLs.
• The system PLL (AVDD2) generates the system clock from the externally supplied CLKIN input.
The frequency ratio between the system and CLKIN is selected using the system PLL ratio
configuration bits as described in Section 22.4, “System PLL Configuration.”
• The e300 core PLL (AVDD3) generates the core clock as a slave to the system clock. The frequency
ratio between the e300 core clock and the system clock is selected using the e300 PLL ratio
configuration bits as described in Section 22.5, “Core PLL Configuration.”
• The QUICC Engine PLL (AVDD1) which uses the same reference as the system PLL. The QUICC
Engine block generates or uses external sources for all required serial interface clocks.
24.2
PLL Power Supply Filtering
Each of the PLLs listed above is provided with power through independent power supply pins. The voltage
level at each AVDDn pin 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 five independent filter circuits as illustrated in Figure 44, 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.
MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4
76
Freescale Semiconductor
System Design Information
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.
Figure 44 shows the PLL power supply filter circuit.

24.3
Decoupling Recommendations
Due to large address and data buses, and high operating frequencies, the MPC8323E 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 MPC8323E system, and the
MPC8323E 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, and GVDD pins of the
MPC8323E. These decoupling capacitors should receive their power from separate VDD, OVDD, GVDD,
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.
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, and GVDD 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).
24.4
Connection Recommendations
To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal
level. Unused active low inputs should be tied to OVDD, or GVDD 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, OVDD, and GND pins of the
MPC8323E.
24.5
Output Buffer DC Impedance
The MPC8323E 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 45). The
MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4

System Design Information
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.

Figure 45. 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 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 Rterm. 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 65 summarizes the signal impedance targets. The driver impedance are targeted at minimum VDD,

Configuration Pin Multiplexing
The MPC8323E 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.
MPC8323E PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 4
78
Freescale Semiconductor
Ordering Information
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. 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.
24.7
Pull-Up Resistor Requirements
The MPC8323E 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.
For more information on required pull-up resistors and the connections required for the JTAG interface,
see AN3361, “MPC8321E/MPC8323E PowerQUICC Design Checklist,” Rev. 1.
