Hardware Specifications
This hardware specification contains detailed information on power considerations, DC/AC
electrical characteristics, and AC timing specifications for the MPC8272 family of
devices—the MPC8272, the MPC8248, the MPC8271, and the MPC8247. These devices are
.13µm (HiP7) members of the PowerQUICC II™ family of integrated communications
processors. They include on a single chip a 32-bit PowerPC™core that incorporates memory
management units (MMUs) and instruction and data caches and that implements the PowerPC
instruction set; a modified communications processor module (CPM); and an integrated
security engine (SEC) for encryption (the MPC8272 and the MPC8248 only).
All four devices are collectively referred to throughout this hardware specification as ‘the
MPC8272’ unless otherwise noted. The following topics are addressed:

4.1
Estimation with Junction-to-Ambient Thermal
Resistance
An estimation of the chip junction temperature, TJ, in °C can be obtained from the equation:
TJ = TA + (RθJA × PD)
where:
TA = ambient temperature (ºC)
RθJA = package junction-to-ambient thermal resistance (ºC/W)
PD = power dissipation in package
The junction-to-ambient thermal resistance is an industry standard value which provides a quick and easy
estimation of thermal performance. However, the answer is only an estimate; test cases have demonstrated
that errors of a factor of two (in the quantity TJ – TA) are possible.

Thermal Characteristics
4.2
Estimation with Junction-to-Case Thermal Resistance
Historically, the thermal resistance has frequently been expressed as the sum of a junction-to-case thermal
resistance and a case-to-ambient thermal resistance:
RθJA = RθJC + RθCA
where:
Freescale Semiconductor, Inc...
RθJA = junction-to-ambient thermal resistance (ºC/W)
RθJC = junction-to-case thermal resistance (ºC/W)
RθCA = case-to-ambient thermal resistance (ºC/W)
RθJC is device related and cannot be influenced by the user. The user adjusts the thermal environment to
affect the case-to-ambient thermal resistance, RθCA. For instance, the user can change the air flow around
the device, add a heat sink, change the mounting arrangement on the printed circuit board, or change the
thermal dissipation on the printed circuit board surrounding the device. This thermal model is most useful
for ceramic packages with heat sinks where some 90% of the heat flows through the case and the heat sink
to the ambient environment. For most packages, a better model is required.
4.3
Estimation with Junction-to-Board Thermal Resistance
A simple package thermal model which has demonstrated reasonable accuracy (about 20%) is a two-resistor
model consisting of a junction-to-board and a junction-to-case thermal resistance. The junction-to-case
thermal resistance covers the situation where a heat sink is used or where a substantial amount of heat is
dissipated from the top of the package. The junction-to-board thermal resistance describes the thermal
performance when most of the heat is conducted to the printed circuit board. It has been observed that the
thermal performance of most plastic packages, especially PBGA packages, is strongly dependent on the
board temperature.
If the board temperature is known, an estimate of the junction temperature in the environment can be made
using the following equation:
TJ = TB + (RθJB × PD)
where:
RθJB = junction-to-board thermal resistance (ºC/W)
TB = board temperature (ºC)
PD = power dissipation in package
If the board temperature is known and the heat loss from the package case to the air can be ignored,
acceptable predictions of junction temperature can be made. For this method to work, the board and board
mounting must be similar to the test board used to determine the junction-to-board thermal resistance,
namely a 2s2p (board with a power and a ground plane) and by attaching the thermal balls to the ground
plane.
4.4
Estimation Using Simulation
When the board temperature is not known, a thermal simulation of the application is needed. The simple
two-resistor model can be used with the thermal simulation of the application, or a more accurate and
complex model of the package can be used in the thermal simulation.

Thermal Characteristics
4.5
Experimental Determination
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:
Freescale Semiconductor, Inc...
ΨJT = thermal characterization parameter
TT = thermocouple temperature on top of package
PD = power dissipation in package
The thermal characterization parameter is measured per JEDEC 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 1 mm of wire extending from the junction. The thermocouple wire is placed
flat against the case to avoid measurement errors caused by cooling effects of the thermocouple wire.

Each VCC pin should be provided with a low-impedance path to the board’s power supply. Each ground pin
should likewise be provided with a low-impedance path to ground. The power supply pins drive distinct
groups of logic on chip. The VCC power supply should be bypassed to ground using at least four 0.1 µF
bypass capacitors located as close as possible to the four sides of the package. The capacitor leads and
associated printed circuit traces connecting to chip VCC and ground should be kept to less than half an inch
per capacitor lead. A four-layer board employing two inner layers as VCC and GND planes is recommended.
All output pins on the MPC8272 have fast rise and fall times. Printed circuit (PC) trace interconnection
length should be minimized in order to minimize overdamped conditions and reflections caused by these
fast output switching times. This recommendation particularly applies to the address and data buses.
Maximum PC trace lengths of six inches are recommended. Capacitance calculations should consider all
device loads as well as parasitic capacitances due to the PC traces. Attention to proper PCB layout and
bypassing becomes especially critical in systems with higher capacitive loads because these loads create
higher transient currents in the VCC and GND circuits. Pull up all unused inputs or signals that will be inputs
during reset. Special care should be taken to minimize the noise levels on the PLL supply pins.

Power Dissipation
Table 7 provides preliminary, estimated power dissipation for various configurations. Note that suitable
thermal management is required to ensure the junction temperature does not exceed the maximum specified
value. Also note that the I/O power should be included when determining whether to use a heat sink. For a
complete list of possible clock configurations, refer to Section 7, “Clock Configuration Modes.”

AC Electrical Characteristics
NOTE
Generally, all MPC8272 bus and system output signals are driven from the
rising edge of the input clock (CLKin). Memory controller signals,
however, trigger on four points within a CLKin cycle. Each cycle is
divided by four internal ticks: T1, T2, T3, and T4. T1 always occurs at the
rising edge, and T3 at the falling edge, of CLKin. However, the spacing of
T2 and T4 depends on the PLL clock ratio selected, as shown in Table 13.

Clock Configuration Modes
As shown in Table 14, the clocking mode is set according to two sources:
•
•
PCI_CFG[0]— An input signal. Also defined as “PCI_HOST_EN.” Refer to the Chapter 6,
“External Signals,” and Chapter 9, “PCI Bridge,” in the MPC8272 PowerQUICC II™ Family
Reference Manual.
PCI_MODCK—Bit 27 in the Hard Reset Configuration Word. Refer to Chapter 5, “Reset,” in the
MPC8272 PowerQUICC II™ Family Reference Manual.

PCI_HOST_EN
Determines PCI clock frequency range.
Within each mode, the configuration of bus, core, PCI, and CPM frequencies is determined by seven bits
during the power-on reset—three hardware configuration pins (MODCK[1–3]) and four bits from hardware
configuration word[28–31] (MODCK_H). Both the PLLs and the dividers are set according to the selected
clock operation mode as described in the following sections.
NOTE
Clock configurations change only after PORESET is asserted.
NOTE: Tval (Output Hold)
The minimum Tval = 2 when PCI_MODCK = 1, and the minimum
Tval = 1 when PCI_MODCK = 0. Therefore, designers should use clock
configurations that fit this condition to achieve PCI-compliant AC timing.
7.1
PCI Host Mode
Table 15 and Table 16 show configurations for PCI host mode. The frequency values listed are for the
purpose of illustration only. Users must select a mode and input bus frequency so that the resulting
configuration does not exceed the frequency rating of the user’s device. Note that in PCI host mode the input
clock is the bus clock.

The “low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency
guarantees the required minimum CPU operating frequency. Minimum CPU frequency is determined by the clock
mode. For modes with a CPU multiplication factor ≤ 3, the minimum CPU frequency is 125 MHz or 150 MHz, as
shown in the table. For modes with a CPU multiplication factor ≥ 3.5, the minimum CPU frequency is 250 MHz.
The “high” values are for the purpose of illustration only. Users must select a mode and input bus frequency so
that the resulting configuration does not exceed the frequency rating of the user’s device.
PCI_MODCK determines the PCI clock frequency range. Refer to Table 16 for lower range configurations.
MODCK_H = hard reset configuration word [28–31] (refer to Section 5.4 in the MPC8260 User’s Manual).
MODCK[1-3] = three hardware configuration pins.
CPM multiplication factor = CPM clock/bus clock
CPU multiplication factor = Core PLL multiplication factor

The “low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency
guarantees the required minimum CPU operating frequency. Minimum CPU frequency is determined by the clock
mode. For modes with a CPU multiplication factor ≤ 3, the minimum CPU frequency is 125 MHz or 150 MHz, as
shown in the table. For modes with a CPU multiplication factor ≥ 3.5, the minimum CPU frequency is 250 MHz.
The “high” values are for the purpose of illustration only. Users must select a mode and input bus frequency so
that the resulting configuration does not exceed the frequency rating of the user’s device.
PCI_MODCK determines the PCI clock frequency range. Refer to Table 15 for higher range configurations.
MODCK_H = hard reset configuration word [28–31] (refer to Section 5.4 in the MPC8260 User’s Manual).
MODCK[1-3] = three hardware configuration pins.
CPM multiplication factor = CPM clock/bus clock
CPU multiplication factor = Core PLL multiplication factor
7.2
PCI Agent Mode
Table 17 and Table 18 show configurations for PCI agent mode. The frequency values listed are for the
purpose of illustration only. Users must select a mode and input bus frequency so that the resulting
configuration does not exceed the frequency rating of the user’s device. Note that in PCI agent mode the
input clock is PCI clock.

The “low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency
guarantees the required minimum CPU operating frequency. Minimum CPU frequency is determined by the clock
mode. For modes with a CPU multiplication factor ≤ 3, the minimum CPU frequency is 125 MHz or 150 MHz, as
shown in the table. For modes with a CPU multiplication factor ≥ 3.5, the minimum CPU frequency is 250 MHz.
The “high” values are for the purpose of illustration only. Users must select a mode and input bus frequency so
that the resulting configuration does not exceed the frequency rating of the user’s device.
PCI_MODCK determines the PCI clock frequency range. Refer to Table 18 for lower range configurations.
MODCK_H = hard reset configuration word [28–31] (refer to Section 5.4 in the MPC8260 User’s Manual).
MODCK[1-3] = three hardware configuration pins.
CPM multiplication factor = CPM clock/bus clock
CPU multiplication factor = Core PLL multiplication factor

The “low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency
guarantees the required minimum CPU operating frequency. Minimum CPU frequency is determined by the clock
mode. For modes with a CPU multiplication factor ≤ 3, the minimum CPU frequency is 125 MHz or 150 MHz, as
shown in the table. For modes with a CPU multiplication factor ≥ 3.5, the minimum CPU frequency is 250 MHz.
The “high” values are for the purpose of illustration only. Users must select a mode and input bus frequency so
that the resulting configuration does not exceed the frequency rating of the user’s device.
PCI_MODCK determines the PCI clock frequency range. Refer to Table 17 for higher range configurations.
MODCK_H = hard reset configuration word [28–31] (refer to Section 5.4 in the MPC8260 User’s Manual).
MODCK[1-3] = three hardware configuration pins.
CPM multiplication factor = CPM clock/bus clock
CPU multiplication factor = Core PLL multiplication factor

Should be tied to VDDH via a 2K Ω external pull-up resistor.
3 The default configuration of the CPM pins (PA[8–31], PB[18–31], PC[0–1,4–29], PD[7–25, 29–31]) is input. To prevent
excessive DC current, it is recommended either to pull unused pins to GND or VDDH, or to configure them as outputs.
4 This pin is not connected. It should be left floating.

NOTE: Temperature Reflow for the VR Package
In the VR package, sphere composition is lead-free (refer to Table 2). This
requires higher temperature reflow than what is required for other
PowerQUICC II packages. Users should consult “Motorola PowerQUICC II™
Pb-Free Packaging Information” (MPC8250PBFREEPKG) available at
www.motorola.com/semiconductors.

Ordering Information
Figure 15 provides an example of the Motorola part numbering nomenclature for the MPC8272. In addition
to the processor frequency, the part numbering scheme also consists of a part modifier that indicates any
enhancement(s) in the part from the original production design. Each part number also contains a revision
code that refers to the die mask revision number and is specified in the part numbering scheme for
identification purposes only. For more information, contact a local Motorola sales office.
