Technical Specifications
Technical Summary
This Quanta Computer Inc. ZRA project (1A148) motherboard, dated March 29, 2010, is built around the AMD Champlain S1G4 PGA processor platform with an SB820 RS880 southbridge. Graphics are handled by an ATI Madison LP 128-bit M2 package GPU. The system utilizes a Winbond KBC for embedded controller functions and an SLG8SP628VTR SPI flash for BIOS storage. Audio is provided by a CX20672-11Z codec, while networking is managed by a BCM 57760 PCIE-LAN controller. The charging circuit is built around an ISL88731 IC. Memory architecture consists of two DDR3-SODIMM slots. Power regulation is handled by multiple dedicated controllers including the ISL6265 for CPU core, UP6111AQDD for NB core and 1.1V rail, MAX8792ETD for GPU core, RT8206 for system 5V/3V, and RT8207 for DDR 1.5V. The board features an 8-layer PCB stack-up and includes an AU6437 card reader controller and an ICS9LPRS476AKLF clock generator.
