Technical Specifications
Technical Summary
This Wistron JV71-TRS motherboard, project code 91.4FP01.001 and board number 48.4FP02.0SB, is built around the AMD Caspian CPU platform using a 638-pin uFCPGA638 socket. The platform integrates an AMD RS880M north bridge with integrated graphics and an AMD SB710 south bridge. System memory is DDR2 running at 667/800 MHz. The embedded controller is a Winbond WPC773, and the BIOS SPI flash is an MXIC MX25L1605. Audio is handled by a Realtek ALC888 codec, and networking by a Broadcom BCM5784L Gigabit LAN controller. The charging IC is a MAX8731, with system power managed by multiple DC/DC converters including the RT8205A, RT9025, TPS51124, RT9161, ISL6265, and RT8209B. A Realtek RTS5159 card reader and an ICS9LPRS480BKLFT clock generator are also present.
