Compatibility and variants
- Soldered embedded BGA device intended for a board designed to the Geode LX datasheet and its companion CS5536 southbridge. Not compatible with PC desktop sockets.
- LX 800 is the 500 MHz member of the LX family; LX 700 and LX 900 are different clock/power grades. Confirm the board-specific CS5536 and power sequencing requirements.
- Confirm the system manufacturer’s exact processor support list, firmware minimum, board revision, power/thermal envelope, and memory requirements before installation.
Service and archival notes
Record the board vendor and complete platform schematic, BIOS, CS5536 revision, and thermal envelope. BGA inspection/rework requires board-level equipment; retain the original embedded board if operational.
Preserve provenance and a record of the exact marking, condition, tested board/platform, firmware, cooling, memory configuration, and test conditions. Separate published specification limits from observations made on a particular surviving system.
