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:
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.
