This device contains protective cir-
cuitry against damage due to high
static voltages or electrical fields;
however, it is advised that normal
precautions be taken to avoid ap-
plication of any voltages higher than
maximum-rated voltages to this
high-impedance circuit. Reliability
of operation is enhanced if unused
inputs are tied to in appropriate
logic voltage level (e.g., either GND
or VCC).
*A continuous clock must be supplied to the MC68030 when it is powered
up.

POWER CONSIDERATIONS
The average chip-junction temperature, T j , in °C can be obtained from:
T j = T A + (PD ° 03A)

' ' " " ":
K = PD" (TA + 273°C) + eJA ° PD2
(3)
where K is a constant pertaining to the particular part. K can be determined
from equation (3) by measuring PD (at equilibrium) for a known TA. Using
this value of K, the values (~f PD and T j can be obtained by solving'equ"ations
(1) and (2) iteratively for any value of T A.
The total thermal resistance of a package (0jA)can be separated into two
components, 0jC and 0CA, representing the barrier to h e a t f l o w from the
semiconductor junction to the package (case) surface (eJC) and from the case
to the outside ambient (0CA). These terms are related by the equation:
0jA=0jC+0CA
(4)
ejC is device related and cannot be influenced by the user. However, 0CA is
user dependent and can be minimized by such thermal management tech-
niques as heat sinks, ambient
air
cooling, and thermal convection. Thus,
good thermal management on the part of the user can significantly reduce
eCA so that 0jA approximately equals 0jC. Substitution of ejC for 0jA in
equation (1) will result in a lower semiconductor junction temperature.
Values for thermal resistance presented in this document, unless.estimated,
were derived using the procedure described in Motorola Reliability Report
7843, "Thermal Resistance Measurement Method for MC68XX Microcom-
ponent Devices," and are provided for design purposes only. Thermal meas-
urements are complex and dependent on procedure and setup. User derived
values for thermal resistance may differ.

AC ELECTRICAL SPECIFICATIONS
DEFINITIONS •
The AC specifications presented consist of output delays, input setup and
hold times, and signal skew times. All signals are specified relative to an
appropriate edge of the MC68030 clock input and, possibly, relative to one
or more other signals.
The measurement of the AC specifications is defined by the waveforms in
Figure 1. To test the parameters guaranteed by MQtorola, inputs must be
driven to the voltage levels •specified in~ Figure 1. Outputs of the MC68030
are specifiedwith minimum.and/or maximum limits, as appropriate, and are
measured as shown. Inputs to the MC68030 are specified with minimum and,
as appropriate, maximum setup and hold times, and are measured asshown.
Finally, the measurements for signal-to-signal specifications are also shown.
Note that the testing levels used to verify conformance of the MC68030 to
the AC specifications:does ~not affect the guaranteed DC operation of the
device as specified in the DC electrical characteristics.
