Technical Specifications
Technical Summary
The Compal ZEJ20 (ZARA 3G) motherboard, board number LA-A792P revision 0.2, is built around the MT8389W/MT8125 Cortex-A7 1.2GHz Quad-Core CPU platform. Graphics processing is handled by the MT8193 GPU, while power management and battery charging are integrated into the MT6320 PMIC. The memory subsystem consists of DDR3L 1GB configured as two 4Gb x16 devices, with a maximum supported VRAM size of 2GB. Wireless connectivity is provided by the NH520T/NH520 module supporting WiFi, Bluetooth 4.0, and GPS. The 3G cellular baseband is managed by the MT6167 modem, and dedicated GPS functionality is handled by the MT3332 GLONASS IC. Motion sensing is provided by the MPU-6050 gyro sensor, touch input by the S7300 touch sensor IC, and proximity detection by the IQS128 sensor.
