10.2 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 were the CPU was running under reset. In TEMIC 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, TEMIC 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 connected and XTAL1
is driven by the clock.
This is much more representative of the real operating Icc.

This value is based on the maximum allowable die temperature and the thermal resistance of the package.
tresses at or above those listed under “ Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only
