Operating Characteristics

Electrical Operating Characteristics

Recommended power supply: VDD= +5V (with tolerance +/-5%)

Power consumption: 13.0 W typical (Pentium III 800MHz, 256MB).

Battery current draw (board off without any device on the SSD): 7 μA.

Note. This module is not warranted against damage caused by overheating due to improper or insufficient cooling or airflow.

Backup Battery Characteristics

There is no configuration data saved by the BIOS into the CMOS Real Time Clock. Therefore, the CPU module does not need a battery, except in the case of applications needing to retrain the date and time at power-off.

Battery Voltage: VBAT= 3.6V (range = 3V to 3.9V)

Note. Setup data is stored into the BIOS Flash EPROM; it is therefore impossible to lose the setup data due to a lack of backup-battery supply.

Operating Temperature Range

For proper operation of the module, the ambient air temperature must remain inside this range: 0°C to +50°C (+32°F to +122°F).

The +50°C test was made at a constant temperature in a climatic chamber.
