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.
Absolute Maximum Ratings
Table 26. Absolute Maximum Ratings
Supply Voltage: Vcc: 0.00 to 7.00V
Storage Temperature Range: -40°C to +85°C (-40°F to +185°F)
Non-Condensing Relative Humidity: <95% at 40°C (+104°F)
Operating Temperature Range: 0°C to +60°C (+32°F to +140°F)
A SpacePC 1232 CPU module with an extended Operating Temperature Range, –40°C to +85°C, is
also available.
Warning! Stressing the device beyond the “Absolute Maximum Ratings” may cause
permanent damage. These are stress ratings only. Operation beyond the “Operating
Conditions” is not recommended. Extended exposure beyond the “Operating
Conditions” may affect device reliability.
