Power Consumption Measurement
Since the introduction of the first C51 devices, every manufacturer made operating I
CC
measurements under reset, which made sense for the designs were the CPU was run-
ning under reset. In our new devices, the CPU is no more active during reset, so the
power consumption is very low but is not really representative of what will happen in the
customer system. That
’
s why, while keeping measurements under Reset, we present a
new way to measure the operating I
CC
:
Using an internal test ROM, the following code is executed:
Label:
SJMP Label (80 FE)
Ports 1, 3, 4 are disconnected, RST =
V
CC
, XTAL2 is not connected and XTAL1 is driven
by the clock.
This is much more representative of the real operating I
CC
.

may cause permanent damage to
the device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational
sections of this specification is not implied. Exposure
to absolute maximum rating conditions may affect
device reliability.
Power dissipation value is based on the maximum
allowable die temperature and the thermal resistance
of the package.
