tresses at or above those listed under “ Absolute 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 specifi-
cation is not implied. Exposure to absolute maximum rating conditions may affect device
reliability.
2. This value is based on the maximum allowable die temperature and the thermal resistance of
the package.
14.2 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 Wireless & Microcontrollers 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 cus-
tomer system. That’s why, while keeping measurements under Reset, Atmel Wireless &
Microcontrollers 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.
