Estimation with Junction-to-Ambient Thermal Resistance
TJ = TA + (RJA x PD)
An estimation of the chip junction temperature, TJ, in C can be obtained from the equation: where: TA = ambient temperature (C) RJA = package junction-to-ambient thermal resistance (C/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
RJA = RJC + RCA
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:
where: RJA = junction-to-ambient thermal resistance (C/W) RJC = junction-to-case thermal resistance (C/W) RCA = case-to-ambient thermal resistance (C/W) RJC is device related and cannot be influenced by the user. The user adjusts the thermal environment to affect the case-to-ambient thermal resistance, RCA. 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.
Freescale Semiconductor, Inc...
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 + (RJB x PD)
where: RJB = junction-to-board thermal resistance (C/W) TB = board temperature (C) 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 (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 x PD)
where: JT = 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.
Freescale Semiconductor, Inc...
4.6
Layout Practices
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 F 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.

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.

0 0 1 1
1 2
Table 15 Table 16 Table 17 Table 18
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.

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

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 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

Must be tied to ground. Should be tied to VDDH via a 2K 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. 5 Must be pulled down or left floating
