Power Consumption Measurement
Since the introduction of the first C51 devices, every manufacturer made operating Icc measure-
ments under reset, which made sense for the designs were the CPU was running under reset. In
Atmel 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, Atmel presents a new way to measure the operating Icc:
Using an internal test ROM, the following code is executed:
Label:
SJMP Label (80 FE)
Ports 1, 2, 3 are disconnected, Port 0 is tied to FFh, EA = Vcc, RST = Vss, XTAL2 is not con-
nected 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 is based on the maximum
allowable die temperature and the thermal resis-
tance of the package.
