General Description
The AMD Geode™ CS5530A companion device is designed to work in conjunction with an AMD Geode™ GX1 processor. Together, the Geode GX1 processor and CS5530A companion device provide a system-level solution well suited for the high performance needs of a host of devices which include digital set-top boxes and thin client devices. Due to the low power consumption of the GX1 processor, this solution satisfies the needs of battery powered devices such as AMD’s WebPAD system, and thermal design is eased allowing for fanless system design.
