Technical Specifications
Technical Summary
The Quanta LE2 project is an Intel Mobile 479 platform supporting 400/533MHz FSB Dothan or Celeron M processors. The system is built around the ICH6-M southbridge in a 609-ball BGA package and features NVIDIA discrete graphics with 32MB or 64MB of dedicated memory. Memory is provided via two DDR2 SODIMM slots. The embedded controller is a 97551 KBC, and the audio subsystem uses an ALC202 codec paired with a MAX9750 amplifier. The BIOS flash is handled by an NSSIO (87383) device. Networking includes a Broadcom LAN controller and a Mini-PCI wireless slot. The clock generation is managed by an ICS954206AG-T clock generator. The charging circuit supports either a 4401 or 5705M charger IC. A PCI7411 controller provides PCMCIA and 1394 FireWire support along with a 3-in-1 card reader.
