Features

Table 1 shows the functionality supported by the members of the MPC862/857T/857DSL family.

Features

The following list summarizes the key MPC862/857T/857DSL features:

Embedded single-issue, 32-bit MPC8xx core (implementing the PowerPC architecture) with
thirty-two 32-bit general-purpose registers (GPRs)

-- The core performs branch prediction with conditional prefetch, without conditional execution

-- 4- or 8-Kbyte data cache and 4- or 16-Kbyte instruction cache (see Table 1).

16-Kbyte instruction cache (MPC862P) is four-way, set-associative with 256 sets; 4-Kbyte

instruction cache (MPC862T, MPC857T, and MPC857DSL) is two-way, set-associative
with 128 sets.

8-Kbyte data cache (MPC862P) is two-way, set-associative with 256 sets; 4-Kbyte data

cache (MPC862T, MPC857T, and MPC857DSL) is two-way, set-associative with 128 sets.

Cache coherency for both instruction and data caches is maintained on 128-bit (4-word)

cache blocks.

Caches are physically addressed, implement a least recently used (LRU) replacement

algorithm, and are lockable on a cache block basis.

-- MMUs support multiple page sizes of 4, 16, and 512 Kbytes, and 8 Mbytes; 16 virtual address

spaces and 16 protection groups

-- Advanced on-chip-emulation debug mode

The MPC862/857T/857DSL provides enhanced ATM functionality over that of the MPC860SAR.
The MPC862/857T/857DSL adds major new features available in "enhanced SAR" (ESAR) mode,
including the following:

-- Improved operation, administration and maintenance (OAM) support

-- OAM performance monitoring (PM) support

-- Multiple APC priority levels available to support a range of traffic pace requirements

-- ATM port-to-port switching capability without the need for RAM-based microcode

-- Simultaneous MII (10/100Base-T) and UTOPIA (half-duplex) capability

Thermal Calculation and Measurement

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:

= R

+ R

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 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:

= T

+(R

x 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

x P

)

where:

= thermal characterization parameter

= thermocouple temperature on top of package

= 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 V

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 V

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 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 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 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.

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.

Table 7 provides the bus operation timing for the MPC862/857T/857DSL at 33 MHz, 40 Mhz, 50 MHz and
66 Mhz.

The timing for the MPC862/857T/857DSL 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 (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 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.

For part speeds above 50MHz, use 9.80ns for B11a.

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.

For part speeds above 50MHz, use 2ns for B17.

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.

For part speeds above 50MHz, use 2ns for B19.

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 19.

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
