Technical Specifications
Technical Summary
This Compal LA-7461P schematic revision 0.3, dated 2010/12/01, documents a motherboard built around the Nvidia Tegra T20 CPU platform with LPDDRII memory architecture. The board utilizes an ENE KBC KB930 embedded controller and a Wolfson WM8903 audio codec. Power management and charging are handled by a TI TPS51220 IC. The system memory configuration is LPDDR2 1GB operating at 1.2V in a X32 bus width. Thermal monitoring is provided by an NCT1008 sensor. Wired connectivity is managed by an SMSC USB3315 ULPI transceiver, while wireless connectivity uses a BCM4751IFBG GPS module. The LVDS bridge is implemented with an SN75LVDS83BZQLR level shifter for HDMI output.
