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:
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 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 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:
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.

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:
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.
4.6 Layout Practices
Each VDD and VDDH pin should be provided with a low-impedance path to the board’s power supplies. 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 VDD and VDDH power supplies should be bypassed to ground using by-pass
capacitors located as close as possible to the four sides of the package. For filtering high frequency noise, a capacitor
of 0.1uF on each VDD and VDDH pin is recommended. Further, for medium frequency noise, a total of 2 capacitors
of 47uF for VDD and 2 capacitors of 47uF for VDDH are also recommnded. The capacitor leads and associated
printed circuit traces connecting to chip VDD, VDDH and ground should be kept to less than half an inch per
capacitor lead. Boards should employ separate inner layers for power 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 VDD 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
6.2 SIU AC Characteristics
NOTE: CLKIN Jitter and Duty Cycle
The CLKIN input to the MPC8280 should not exceed +/– 150 psec of jitter
(peak-to-peak). This represents total input jitter—the combination of short term
(cycle-to-cycle) and long term (cumulative). The duty cycle of CLKIN should not
exceed the ratio of 40:60. The rise/file time of CLKIN should adhere to the typical
SDRAM device AC clock requirement of 1 V/ns to meet SDRAM AC specs.
NOTE: Spread Spectrum Clocking
Spread spectrum clocking is allowed with 1% input frequency down-spread at
maximum 60 KHz modulation rate regardless of input frequency.
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.

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.

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.
Time-of-flight delays must be added for trace lengths, vias, and connectors in the system.
The symbols used for timing specifications herein 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).
TRST is an asynchronous level sensitive signal. The setup time is for test purposes only.
Non-JTAG signal input timing with respect to tTCLK.
Non-JTAG signal output timing with respect to tTCLK.

Clock Configuration Modes
The MPC8280 has three clocking modes: local, PCI host, and PCI agent. The clocking mode is set according to three

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 16 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.

The “low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency in a
table entry guarantees only the required minimum CPU operating frequency. 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
violate the frequency rating of the user’s device. The minimum CPM frequency is 120 MHz. Minimum CPU frequency
is determined by the clock mode. For modes with a CPU multiplication factor <= 3, the minimum CPU frequency is
150 MHz for commercial temperature devices and 175 MHz for extended temperature devices. For modes with a CPU
multiplication factor >= 3.5: for Rev0.1 the minimum CPU frequency is 250 MHz; for RevA or later the minimum CPU
frequency is 150 MHz for commercial temperature devices and 175 MHz for extended temperature devices.
MODCK_H = hard reset configuration word [28–31]. MODCK[1-3] = three hardware configuration pins.
60x and local bus frequency. Identical to CLKIN.
CPM multiplication factor = CPM clock/bus clock

Clock Configuration Modes
7.2 PCI Host Mode
Table 17 and Table 18 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:
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 ns when PCI_MODCK = 1, and the minimum Tval = 1 ns
when PCI_MODCK = 0. Therefore, designers should use clock configurations that
fit this condition to achieve PCI-compliant AC timing.

The “low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency in a table
entry guarantees only the required minimum CPU operating frequency. 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 violate
the frequency rating of the user’s device. The minimum CPM frequency is 120 MHz. Minimum CPU frequency is
determined by the clock mode. For modes with a CPU multiplication factor <= 3, the minimum CPU frequency is 150
MHz for commercial temperature devices and 175 MHz for extended temperature devices. For modes with a CPU
multiplication factor >= 3.5: for Rev0.1 the minimum CPU frequency is 250 MHz; for RevA or later the minimum CPU
frequency is 150 MHz for commercial temperature devices and 175 MHz for extended temperature devices.
As Table 15 shows, PCI_MODCK determines the PCI clock frequency range. Refer to Table 18 for lower configurations.
MODCK_H = hard reset configuration word [28–31]. MODCK[1-3] = three hardware configuration pins.
60x and local bus frequency. Identical to CLKIN.
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 in a table
entry guarantees only the required minimum CPU operating frequency. 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 violate the frequency
rating of the user’s device. The minimum CPM frequency is 120 MHz. Minimum CPU frequency is determined by the clock
mode. For modes with a CPU multiplication factor <= 3, the minimum CPU frequency is 150 MHz for commercial
temperature devices and 175 MHz for extended temperature devices. For modes with a CPU multiplication factor >= 3.5:
for Rev0.1 the minimum CPU frequency is 250 MHz; for RevA or later the minimum CPU frequency is 150 MHz for
commercial temperature devices and 175 MHz for extended temperature devices.
As Table 15 shows, PCI_MODCK determines the PCI clock frequency range. Refer to Table 17 for higher configurations.
MODCK_H = hard reset configuration word [28–31]. MODCK[1-3] = three hardware configuration pins.
60x and local bus frequency. Identical to CLKIN.
CPM multiplication factor = CPM clock/bus clock
CPU multiplication factor = Core PLL multiplication factor
7.3 PCI Agent Mode
Table 19 and Table 20 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 ns when PCI_MODCK = 1, and the minimum Tval = 1 ns
when PCI_MODCK = 0. Therefore, designers should use clock configurations that
fit this condition to achieve PCI-compliant AC timing.

entry guarantees only the required minimum CPU operating frequency. 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 violate
the frequency rating of the user’s device. The minimum CPM frequency is 120 MHz. Minimum CPU frequency is
determined by the clock mode. For modes with a CPU multiplication factor <= 3, the minimum CPU frequency is 150
MHz for commercial temperature devices and 175 MHz for extended temperature devices. For modes with a CPU
multiplication factor >= 3.5: for Rev0.1 the minimum CPU frequency is 250 MHz; for RevA or later the minimum CPU
frequency is 150 MHz for commercial temperature devices and 175 MHz for extended temperature devices.
As shown in Table 15, PCI_MODCK determines the PCI clock frequency range. Refer to Table 20 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

The “low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency in a table
entry guarantees only the required minimum CPU operating frequency. 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 violate
the frequency rating of the user’s device. The minimum CPM frequency is 120 MHz. Minimum CPU frequency is
determined by the clock mode. For modes with a CPU multiplication factor <= 3, the minimum CPU frequency is 150
MHz for commercial temperature devices and 175 MHz for extended temperature devices. For modes with a CPU
multiplication factor >= 3.5: for Rev0.1 the minimum CPU frequency is 250 MHz; for RevA or later the minimum CPU
frequency is 150 MHz for commercial temperature devices and 175 MHz for extended temperature devices.
As shown in Table 15, PCI_MODCK determines the PCI clock range. Refer to Table 19 for higher range configurations.

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 (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 4.6,
“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.
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 21 are described in Table 22.

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 “Freescale PowerQUICC II™ Pb-Free Packaging
Information” (MPC8250PBFREEPKG) available at www.freescale.com.

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 4.6, “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.
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.
