7.1Estimation with Junction-to-Ambient Thermal Resistance
An estimation of the chip junction temperature, TJ, in °C can be obtained from the equation:
TJ = TA + (R

× PD)
where:
TA = ambient temperature (ºC)
R
= package j unction-to-a mbient ther mal resistance (ºC/W)
θJA
PD = power dissipation in package
The junction-to-a mbient thermal resis tance is an industry s tandard value whic h provides a quick and eas y estimation
of thermal perform ance. However , the answer is o nly an estimate; t est cases have demo nstrated that err ors of a factor
of two (in the quantity T
– TA) are possible.

7.2Estimation 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:

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.
7.3Estimation with Junction-to-Board Thermal Resistance
A simple package thermal mode l which has demonst rated re asonable ac curacy (abo ut 20%) is a two-resi stor model
consisting of a junc ti on-to- board and a ju nctio n-to- case t herma l res ista nce. The j unc tion- to-ca se the rmal re sist ance
covers the situ ation where a heat sink i s u sed or where a subst antia l am ount of heat is di ssipa ted from t he top of the
package. The junction-to-board thermal resistance describes the thermal performance when most of the heat is
conducted to the pri nt ed c ir cui t boa rd. It has been observ ed t hat the thermal perf or mance of most plastic pa cka ges ,
especially PBGA packages, is strongly dependent on the board temperature; see
Figure 1.

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 + (R
θJB
× PD)
where:
R
= junction-to-board thermal resistance (ºC/W)
θJB
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.

7.4Estimation Using Simulation
When the board temperatur e is not known, a therma l simulation of the appl ication is needed . The simple two-resistor
model can be used with the therma l simula tion of t he app licat ion [2] , or a more ac curate and co mple x model of the
package can be used in the thermal simulation.
7.5Experimental Determination
To determine the junction temperature of the device in the application after prototypes are available, the thermal
characterization parameter (Ψ
temperature at the top center of the package case using the following equation:
TJ = TT + (ΨJT × PD)
where:
Ψ
= thermal characterization parameter
JT
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 juncti on rests on the p ackage. A small a mount of ep oxy is placed o ver the thermocoupl e juncti on 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-impe dance path to th e 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 V

Bus Signal Timing
All output pins on the MPC860 have fa st rise and fall times. Printed c ircuit (PC) tr ace interc onnection le ngth 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. Capaci tance calc ulations s hould conside r all devi ce loads as well as pa rasitic c apacitances 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
CC
inputs or signals that will be inputs during reset. Special care should be taken to minimize the noise levels on the
PLL supply pins.
9Bus 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 i s 6 6 MHz. Hi ghe r-speed parts must be operated in half -s pee d
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.
2
If the rate of change of the fre quency of EXTAL is slow (that is, it does not jump b etween the minim um and maxi mum
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%.
3
The timings specified in B4 and B5 are based on full strength clock.
4
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.
5
The timing required fo r 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.
6
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.
7
The D(0:31) and DP(0:3) in put timing s B20 and B21 refer to the fa lling edge of t he CLKOUT. This timing is valid only
for read accesses con trolled by chip-sel ects u nder control of the UPM in th e memory c ontroller, 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.)

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 functi ons correctl y up to a MII_RX_CLK ma ximum frequency of 25 MHz +1%. There is no minimum
frequency requirement . In addit ion, the proces sor clo ck frequ ency mu st exce ed the MII_ RX_CLK frequen cy – 1%.

The transmitter functions correctly up to a MII_TX_CLK maximum frequency of 25 MHz +1%. Ther e is no
minimum frequency requirement. In addition, the processor clock frequency must exceed the MII_TX_CLK
frequency – 1%.
