Power Management
Standby mode. The internal clocks will shut down, thus freezing the
pipeline. The PLL, internal timer, and some of the input pins (Int[5:0]*,
NMI*, ExtReq*, Reset*, and ColdReset*) will continue to run. Once the
CPU is in Standby Mode, any interrupt, including the internally gener-
ated timer interrupt, will cause the CPU to exit Standby Mode.
Thermal Considerations
are guaranteed in a case temperature range of 0° to +85° C, for
commercial temperature devices; - 40° to +85° for industrial tempera-
ture devices. The type of package, speed (power) of the device, and
airflow conditions affect the equivalent ambient temperature conditions
that will meet this specification.

tures:

ment, which substantially reduces the typical power dissipation of the
device.
