Technical Specifications
Technical Summary
The Compal ZEJ20 (ZARA 3G) motherboard, documented under board number LA-A792P revision 0.1 dated 2013-05-20, 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 is managed by the MT6320 PMIC. The memory subsystem consists of DDR3L 1GB configured as two 4Gb X16 chips, with a maximum supported VRAM size of 2GB. Wireless connectivity is provided by the NH520T/NH520 WiFi/BT/GPS module, and dedicated GPS functionality is handled by the MT3332 GLONASS IC. The 3G baseband is managed by the MT6167 GSM/BSIP sensor. Touch input is controlled by the S7300 touch sensor IC and the IQS128 capacitive touch panel controller. Motion sensing is provided by the MPU-6050 gyro sensor. The audio subsystem connects via the LA401P (Audio/B) audio board connector.
