Technical Specifications
Technical Summary
The Quanta ZW1L motherboard, board number 31ZW1MB0004 revision 3E, is built around a Micro-FCPGA CPU platform with an ICH4-M southbridge. Graphics are handled by an ATI M7/M9 video controller. The system uses DDR SDRAM at 2.5V and 266MHz across two DDR-SODIMM slots. The embedded controller is a PC87591, and the audio codec is a TI-TPA43AB21. Networking is provided by a BCM4401/5702 LAN IC, and a MINI-PCI slot supports WLAN expansion. The charging architecture is AC/BATT managed by a MICREL 280 charging IC. A CPU thermal sensor is present for temperature monitoring. The card reader is controlled by an O2 OZ6912 IC.
