Technical Specifications
Technical Summary
The Wistron EGRET project, board number A3150 revision A3, is an AMD K8 platform based on the Claw Hammer processor. The system architecture is built around a VIA K8N800 northbridge with integrated graphics and a VIA VT8235CE southbridge. Memory is supported via a single 200-pin DDR SODIMM slot. The embedded controller is an M38859, and the system BIOS is stored on an SST 49LF040 flash IC. Audio is handled by a VT1612A AC'97 codec, while networking is provided by a Realtek RTL8110SBL Gigabit LAN controller. Power management includes a MAX1645BEEI battery charger, a MAX1999 system power IC, and an ISL6559CR CPU core voltage regulator. The platform also features a VIA VT1623M TV encoder and a VIA VT1631 LVDS transmitter for display output.
