NOTE: Core, PLL, and I/O Supply Voltages
After power up sequence is complete, VDDH and VDD/VCCSYN must
track each other and both voltages must vary in the same direction. When
varying in the positive direction, VDDH may vary up to 5% from nominal
or 3.3 + 0.165 = 3.465 V, in which case VDD/VCCSYN must also vary
upward by 5% from nominal or 1.525 + 0.075 = 1.6 V. The same applies
to the negative direction: VDDH may vary downward up to -5% from
nominal or 3.3 –0.165 = 3.135 V, in which case VDD/VCCSYN must vary
downward by-5% from nominal or 1.525 –0.075 = 1.45 V. A/C timing
specification violation may occur during the time that voltage tracking is
not correct.
This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage level (either GND or V ).

written as Psi-JT.
4.1
Estimation with Junction-to-Ambient Thermal
Resistance
An estimation of the chip junction temperature, TJ, in °C can be obtained from the following equation:
TJ = TA + (RθJA × PD)
where:
T = ambient temperature (ºC)
A
R
= package junction-to-ambient thermal resistance (ºC/W)
θJA
P = power dissipation in package
D
The junction-to-ambient thermal resistance is an industry standard value that 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 T – T ) are possible.

4.2
Experimental Determination
To determine the junction temperature of the device in the application after prototypes are available, the
thermal characterization parameter (Ψ ) can be used to determine the junction temperature with a
JT
measurement of the temperature at the top center of the package case using the following equation:
TJ = TT + (ΨJT × PD)
where:
Ψ
= thermal characterization parameter
JT
T = thermocouple temperature on top of package
T
P = power dissipation in package
D
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.
4.3
Layout Practices
Each V pin should be provided with a low-impedance path to the board’s power supply. Each ground pin
CC
should likewise be provided with a low-impedance path to ground. The power supply pins drive distinct
groups of logic on chip. The V power supply should be bypassed to ground using at least four 0.1 µF
CC
by-pass capacitors located as close as possible to the four sides of the package. The capacitor leads and
associated printed circuit traces connecting to chip V and ground should be kept to less than half an inch
CC
per capacitor lead.A four-layer board is recommended, employing two inner layers asVCC and GND planes.
All output pins on the MPC8280 have fast rise and fall times. Printed circuit (PC) trace interconnection
length should be minimized 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 V and GND circuits. Pull up all unused inputs or signals that will be inputs during reset.
CC
Special care should be taken to minimize the noise levels on the PLL supply pins.

NOTE: CLKIN Jitter and Duty Cycle
The CLKIN input to the MPC8280 should not exceed +/– 150 psec. This
represents total input jitter—the combination of short term (peak-to-peak)
and long term (cumulative). The duty cycle of CLKIN should not exceed
the ratio of 40:60.
NOTE: PCI AC Timing
The MPC8280 meets the timing requirements of PCI Specification
Revision 2.2. Refer to Sections 7.2 and 7.3 and “Note: Tval (Output Hold)”
to determine if a specific clock configuration is compliant.

NOTE
Generally, all MPC8280 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
In each clocking mode, the configuration of bus, core, PCI, and CPM frequencies is determined by seven
bits during the power-up 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 MPC8280 clock operation mode as described in the following sections.
7.1
Local Bus Mode
Table 15 lists clock configurations for the MPC8280 in local bus mode. The frequencies 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
Clock configurations change only after PORESET is asserted.

“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 166 MHz. The minimum CPM
frequency is 133 MHz.
For modes with a CPU multiplication factor ≥ 3.5, the minimum CPU frequency is 250 MHz. The minimum CPM
frequency is as shown in the table.
“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 Host Mode
Table 16 and Table 17 show clock configurations for PCI host mode. The frequencies 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. In addition, note the following:

Clock Configuration Modes
NOTE: PCI_MODCK
In PCI mode only, PCI_MODCK comes from the LGPL5 pin and
MODCK_H[0–3] comes from {LGPL0, LGPL1, LGPL2, LGPL3}.
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.

“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 166 MHz.The minimum CPM frequency
is 133 MHz.
For modes with a CPU multiplication factor ≥ 3.5, the minimum CPU frequency is 250 MHz. The minimum CPM
frequency is as shown in the table.
“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.

Clock Configuration Modes

“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 166 MHz. The minimum CPM frequency
is 133 MHz.
For modes with a CPU multiplication factor ≥ 3.5, the minimum CPU frequency is 250 MHz.The minimum CPM frequency
is as shown in the table.
“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 Agent Mode
Table 18 and Table 19 show configurations for PCI agent mode. The frequencies 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. In addition, note the following:
NOTE: PCI_MODCK
In PCI mode only, PCI_MODCK comes from the LGPL5 pin and
MODCK_H[0–3] comes from {LGPL0, LGPL1, LGPL2, LGPL3}.
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.

“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 166 MHz.The minimum CPM frequency
is 133 MHz.
For modes with a CPU multiplication factor ≥ 3.5, the minimum CPU frequency is 250 MHz. The minimum CPM
frequency is as shown in the table.
“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.

As shown in Table 14, PCI_MODCK determines the PCI clock frequency range. Refer to Table 19 for lower
configurations.

MODCK_H = hard reset configuration word [28–31]. MODCK[1-3] = three hardware configuration pins.
CPM multiplication factor = CPM clock/PCI clock
CPU multiplication factor = Core PLL multiplication factor

“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 166 MHz.The minimum CPM frequency
is 133 MHz.
For modes with a CPU multiplication factor ≥ 3.5, the minimum CPU frequency is 250 MHz. The minimum CPM
frequency is as shown in the table.
“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.

As shown in Table 14, PCI_MODCK determines the PCI clock range. Refer to Table 18 for higher range configurations.
MODCK_H = hard reset configuration word [28–31]. MODCK[1-3] = three hardware configuration pins.
CPM multiplication factor = CPM clock/PCI clock
CPU multiplication factor = Core PLL multiplication factor

Should be tied to VDDH via a 2K Ω external pull-up resistor.
The default configuration of the CPM pins (PA[0–31], PB[4–31], PC[0–31], PD[4–31]) is input. To prevent excessive
DC current, it is recommended to either pull unused pins to GND or VDDH, or to configure them as outputs.

GNDSYN (AB1): This pin exists as a separate ground signal in MPC826x(A) devices; it does not exist as a separate
ground signal on the MPC8280. New designs must connect AB1 to GND and follow the suggestions in Section 4.3,
“Layout Practices.” Old designs in which the MPC8280 is used as a drop-in replacement can leave the pin connected
to GND with the noise filtering capacitors.
7
XFC (AB2) pin: This pin is used in MPC826x(A) devices; it is not used in MPC8280 because there is no need for
external capacitor to operate the PLL. New designs should connect AB2 (XFC) pin to GND. Old designs in which the
MPC8280 is used as a drop-in replacement can leave the pin connected to the current capacitor.
Symbols used in Table 20 are described in Table 21.

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.
Table 22 shows the pinout list of the MPC8275 and MPC8270. Table 21 defines conventions and acronyms

Should be tied to VDDH via a 2K Ω external pull-up resistor.
The default configuration of the CPM pins (PA[0–31], PB[4–31], PC[0–31], PD[4–31]) is input. To prevent excessive
DC current, it is recommended to either pull unused pins to GND or VDDH, or to configure them as outputs.

Must be pulled down or left floating.
If PCI is not desired, must be pulled up or left floating.
Sphere is not connected to die.
GNDSYN (B18): This pin exists as a separate ground signal in MPC826x(A) devices; it does not exist as a separate
ground signal on the MPC8275/MPC8270. New designs must connect B18 to GND and follow the suggestions in
Section 4.3, “Layout Practices.” Old designs in which the MPC8275/MPC8270 is used as a drop-in replacement can
leave the pin connected to GND with the noise filtering capacitors.
7
XFC (A18) pin: This pin is used in MPC826x(A) devices; it is not used in MPC8275/MPC8270 because there is no
need for external capacitor to operate the PLL. New designs should connect A18 (XFC) pin to GND. Old designs in
which the MPC8275/MPC8270 is used as a drop-in replacement can leave the pin connected to the current capacitor.
