Hardware Specifications
This hardware specification contains detailed information on
power considerations, DC/AC electrical characteristics, and AC
timing specifications for the MPC860 family.

Overview
The MPC860 Power Quad Integrated Communications Controller
(PowerQUICC™) is a versatile one-chip integrated
microprocessor and peripheral combination designed for a variety
of controller applications. It particularly excels in
communications and networking systems. The PowerQUICC unit
is referred to as the MPC860 in this hardware specification.
The MPC860 implements the PowerPC architecture and contains
a superset of Freescale’s MC68360 Quad Integrated
Communications Controller (QUICC™), referred to here as the
QUICC, RISC Communications Proccessor Module (CPM). The
CPM from the MC68360 QUICC has been enhanced by the
addition of the inter-integrated controller (I2C) 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.

Thermal Calculation and Measurement
For the following discussions, PD = (VDD × IDD) + 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, 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.
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:
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

Thermal Calculation and Measurement
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
Junction Temperature Rise Above
Ambient Divided by Package Power
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; see Figure 1.
Board Temperature Rise Above Ambient Divided by Package Power
Figure 1. Effect of Board Temperature Rise on Thermal Behavior
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.

Layout Practices
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 (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 package case to
avoid measurement errors caused by cooling effects of the thermocouple wire.

Each VDD 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 the chip. The VDD 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 VDD and GND 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.

Bus Signal Timing
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 buses. 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 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.

Bus Signal Timing
Table 7 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).
The timing for the MPC860 bus shown assumes a 50-pF load for maximum delays and a 0-pF load for minimum
delays.

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 (that is, it does not jump between the minimum and maximum
values in one cycle) or the frequency of the jitter is fast (that is, 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 17.

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

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 have
no direct relation with the total system interrupt latency that the MPC860 is able to support.

These synchronous timings define when the WAITx signals are detected in order to freeze (or relieve) the
PCMCIA current cycle. The WAITx assertion will be effective only if it is detected 2 cycles before the PSL
timer expiration. See Chapter 16, “PCMCIA Interface,” in the MPC860 PowerQUICC User’s Manual.

13 FEC Electrical Characteristics
This section provides the AC electrical specifications for the Fast Ethernet controller (FEC). Note that the timing
specifications for the MII signals are independent of system clock frequency (part speed designation). Also, MII
signals use TTL signal levels compatible with devices operating at either 5.0 V or 3.3 V.
13.1 MII Receive Signal Timing (MII_RXD[3:0], MII_RX_DV,
MII_RX_ER, MII_RX_CLK)
The receiver functions correctly up to a MII_RX_CLK maximum frequency of 25 MHz +1%. There is no minimum
frequency requirement. In addition, the processor clock frequency must exceed the MII_RX_CLK frequency – 1%.
Table 29 provides information on the MII receive signal timing.
