Note. In order to ensure proper operation and good reliability up to +60°C of ambient air temperature, the Geode GX1 chip and the Geode CS5530 I/O Companion are supplied with an

attached passive heat sink.

Battery Backup Characteristics

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

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.
