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 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:
SJMP Label (80 FE)
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.
DC Parameters for
Standard Voltage
TA = 0°C to +70°C; VSS = 0 V; VCC = 5V ± 10%; F = 0 to 40 MHz.
TA = -40°C to +85°C; VSS = 0 V; VCC = 5V ± 10%; F = 0 to 40 MHz.
Ambiant Temperature Under Bias:
C = commercial......................................................0°C to 70°C
I = industrial ........................................................-40°C to 85°C
Storage Temperature .................................... -65°C to + 150°C
Voltage on VCC to VSS .........................................-0.5V to + 7 V
Voltage on VPP to VSS .......................................-0.5V to + 13 V
Voltage on Any Pin to VSS..........................-0.5V to VCC + 0.5V
Power Dissipation ........................................................... 1 W(2)
Notes: 1.
Stresses at or above those listed under “ Absolute
Maximum Ratings” may cause permanent dam-
age 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.
2. This value is based on the maximum allowable die
temperature and the thermal resistance of the
package.
