Since the introduction of the first C51 devices, every manufacturer made operating Icc
measurements under reset, which made sense for the designs were the CPU was run-
ning 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 pre-
sents a new way to measure the operating Icc:
Using an internal test ROM, the following code is executed:
Label:
Ports 1, 2, 3 are disconnected, Port 0 is tied to FFh, EA = Vcc, RST = Vss, XTAL2 is not
connected and XTAL1 is driven by the clock.
This is much more representative of the real operating Icc.
