Technical Specifications
Technical Summary
This Compal LA-7251P (PBJ30) reference design is built around the NVIDIA Tegra250 (T20) SoC, integrating both CPU and GPU on a single FCBGA package. The platform utilizes LPDDR POP memory configurable to 512MB or 1GB. System management is handled by an ENE KB930 EC/KBC, while power delivery is managed by a TPS658621 PMIC and BQ24725 charging IC. Audio processing is split between an ALC105 codec and a Wolfson WM8903 amplifier. Connectivity includes an AzureWave AW-NH611 WLAN/BT module, SMSC USB3315 ULPI PHY, and PS8122 signal switch for docking. The board features a comprehensive sensor suite including KXTF9-4100 G-sensor, MPU-3050 gyro, AKM8975 e-compass, and AL3000 light sensor. Display output is provided via an SN75LVDS83B LVDS bridge, and thermal monitoring is handled by an NCT1008 sensor.
