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 In our new devices, the CPU is no longer active during reset, so the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

tresses at or above those listed under “Abso-
lute Maximum Ratings” may cause permanent
damage to the device. This is a stress rating only
and functional operation of the device at these or
any other conditions 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 maxi-
mum allowable die temperature and the thermal
resistance of the package.
