The power supply of the device must start its ramp from 0.0 V.
Functional operating conditions are provided with the DC electrical specifications in Table 5. Absolute maximum
ratings are stress ratings only; functional operation at the maxima is not guaranteed. Stress beyond those listed
may affect device reliability or cause permanent damage to the device.
Caution: All inputs that tolerate 5 V cannot be more than 2.5 V greater than the supply voltage. This restriction
applies to power-up and normal operation (that is, if the MPC862/857T/857DSL is unpowered, voltage greater
than 2.5 V must not be applied to its inputs).
3 Minimum temperatures are guaranteed as ambient temperature, T . Maximum temperatures are guaranteed as
A
junction temperature, Tj.
4 JTAG is tested only at ambient, not at standard maximum or extended maximum.

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 (for example, either GND or VCC).

Thermal Calculation and Measurement
For the following discussions, PD= (VDD x 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 x 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.

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.
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 3.

Thermal Calculation and Measurement
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 x 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 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 (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 x 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 JESD51-2 specification published by JEDEC
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.

Layout Practices
Each VCC pin on the MPC862/857T/857DSL 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 VCC power supply should be bypassed to ground
using at least four 0.1 µF 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 VCC 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 VCC and GND planes.
All output pins on the MPC862/857T/857DSL 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 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.

Bus Signal Timing
The maximum bus speed supported by the MPC862/857T/857DSL is 66 MHz. Higher-speed parts must
be operated in half-speed bus mode (for example, an MPC862/857T/857DSL used at 80MHz must be
configured for a 40 MHz bus). Table 6 shows the period ranges for standard part frequencies.

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%.
3 The timings specified in B4 and B5 are based on full strength clock.
4 The timing for BR output is relevant when the MPC862/857T/857DSL is selected to work with external bus arbiter.
The timing for BG output is relevant when the MPC862/857T/857DSL is selected to work with internal bus arbiter.
5 For part speeds above 50MHz, use 9.80ns for B11a.
6 The timing required for BR input is relevant when the MPC862/857T/857DSL is selected to work with internal bus
arbiter. The timing for BG input is relevant when the MPC862/857T/857DSL is selected to work with external bus
arbiter.
7 For part speeds above 50MHz, use 2ns for B17.
8 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.
9
For part speeds above 50MHz, use 2ns for B19.
10 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.)
11 The timing B30 refers to CS when ACS = 00 and to WE(0:3) when CSNT = 0.
12 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 19.
13 The AS signal is considered asynchronous to the CLKOUT. The timing B39 is specified in order to allow the behavior
specified in Figure 22.

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 MPC862/857T/857DSL is able to
support.

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). Furthermore, MII signals use TTL signal levels compatible with devices operating at either
5.0 or 3.3 V.

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 25MHz +1%. There is no
minimum frequency requirement. In addition, the processor clock frequency must exceed the
MII_RX_CLK frequency - 1%.
