Part I Overview

The MPC860 Quad Integrated Communications Controller (PowerQUICCTM)
is a versatile one-chip integrated microprocessor and peripheral combination
designed for a variety of controller applications. It particularly excels in both
communications and networking systems. The PowerQUICC unit is referred to
as the MPC860 in this manual.

The MPC860 is a derivative of Motorola's MC68360 Quad Integrated
Communications Controller (QUICC

), referred to here as the QUICC, that

implements the PowerPC architecture. The CPU on the MPC860 is a 32-bit

Features

MPC8xx core that incorporates memory management units (MMUs) and instruction and
data caches and that implements the PowePC instruction set. The communications
processor module (CPM) from the MC68360 QUICC has been enhanced by the addition of
the inter-integrated controller (I

C) channel. The memory controller has been enhanced,

enabling the MPC860 to support any type of memory, including high-performance
memories and new types of DRAMs. A PCMCIA socket controller supports up to two
sockets. A real-time clock has also been integrated.

Table 1 shows the functionality supported by the members of the MPC860 family.

For the following discussions, P

) + PI/O, where PI/O is the power

dissipation of the I/O drivers.

7.1

Estimation with Junction-to-Ambient Thermal
Resistance

An estimation of the chip junction temperature, T

, in °C can be obtained from the equation:

= T

+ (R

)

where:

= ambient temperature (ºC)

= package junction-to-ambient thermal resistance (ºC/W)

= 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 T

)

are possible.

7.2

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:

Estimation with Junction-to-Board Thermal Resistance

where:

= junction-to-ambient thermal resistance (ºC/W)

= junction-to-case thermal resistance (ºC/W)

= case-to-ambient thermal resistance (ºC/W)

is device related and cannot be influenced by the user. The user adjusts the thermal

environment to affect the case-to-ambient thermal resistance, R

. 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.

7.3

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 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 and especially PBGA packages is strongly dependent on the board
temperature; see Figure 7-1.

Estimation Using Simulation

If the board temperature is known, an estimate of the junction temperature in the
environment can be made using the following equation:

= T

+ (R

× P

)

where:

= junction-to-board thermal resistance (ºC/W)

= board temperature (ºC)

= 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 vias attaching the thermal balls to the ground plane.

7.4

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 [2], or a more accurate and complex model of the package can be used in the
thermal simulation.

7.5

Experimental Determination

To determine the junction temperature of the device in the application after prototypes are
available, the thermal characterization parameter (

) 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:

= T

+ (

× P

)

where:

= thermal characterization parameter

= thermocouple temperature on top of package

= 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 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.

Part VIII Layout Practices

Each V

pin on the MPC860 should be provided with a low-impedance path to the board's

supply. Each GND pin 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-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 V

and GND should be kept to less than half an inch per

capacitor lead. A four-layer board is recommended, employing two inner layers as V

and

GND planes.

All output pins on the MPC860 have fast rise and fall times. Printed circuit (PC) trace
interconnection length should be minimized in order to minimize undershoot and
reflections caused by these fast output switching times. This recommendation particularly
applies to the address and data busses. Maximum PC trace lengths of 6 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. Special care should be taken to minimize the noise
levels on the PLL supply pins.

Part IX Bus Signal Timing

Table 9-6 provides the bus operation timing for the MPC860 at 33, 40, 50, and 66 MHz.

The maximum bus speed supported by the MPC860 is 66 MHz. Higher-speed parts must
be operated in half-speed bus mode (for example, an MPC860 used at 80 MHz must be
configured for a 40 MHz bus).

Phase and frequency jitter performance results are only valid if the input jitter is less than the prescribed value.

If the rate of change of the frequency of EXTAL is slow (i.e., it does not jump between the minimum and maximum
values in one cycle) or the frequency of the jitter is fast (i.e., it does not stay at an extreme value for a long time) then
the maximum allowed jitter on EXTAL can be up to 2%.

The timings specified in B4 and B5 are based on full strength clock.

The timing for BR output is relevant when the MPC860 is selected to work with external bus arbiter. The timing for BG
output is relevant when the MPC860 is selected to work with internal bus arbiter.

The timing required for BR input is relevant when the MPC860 is selected to work with internal bus arbiter. The timing
for BG input is relevant when the MPC860 is selected to work with external bus arbiter.

The D(0:31) and DP(0:3) input timings B18 and B19 refer to the rising edge of the CLKOUT in which the TA input
signal is asserted.

The D(0:31) and DP(0:3) input timings B20 and B21 refer to the falling edge of the CLKOUT. This timing is valid only
for read accesses controlled by chip-selects under control of the UPM in the memory controller, for data beats where
DLT3 = 1 in the UPM RAM words. (This is only the case where data is latched on the falling edge of CLKOUT.)

The timing B30 refers to CS when ACS = 00 and to WE(0:3) when CSNT = 0.

The signal UPWAIT is considered asynchronous to the CLKOUT and synchronized internally. The timings specified
in B37 and B38 are specified to enable the freeze of the UPM output signals as described in Figure 9-17.

The AS signal is considered asynchronous to the CLKOUT. The timing B39 is specified in order to allow the behavior
specified in Figure 9-20.

Characteristic

The timings I39 and I40 describe the testing conditions under which the IRQ lines are tested when being defined as
level sensitive. The IRQ lines are synchronized internally and do not have to be asserted or negated with reference
to the CLKOUT.
The timings I41, I42, and I43 are specified to allow the correct function of the IRQ lines detection circuitry, and has
no direct relation with the total system interrupt latency that the MPC860 is able to support.
