Acer Chromebook C731 Quanta ZHM Rev A1A Schematic
Technical Specifications
Technical Summary
This Quanta ZHM Chromebook motherboard is built on the Intel Braswell platform with a TDP of 6 Watts. The system memory consists of 4 pieces of LPDDR3 soldered down. The embedded controller is a Microchip MEC1322-LZYP in a DQFN132 package, communicating via LPC and SPI interfaces. The BIOS SPI flash is a Winbond W25Q64FW with a capacity of 64Mb. Power management is handled by a PMIC RT5067, with additional voltage regulation from RT7290, RT7291, and RT9610 MOSFETs paired with CSD87381P. The charging solution is a BQ24770 NVDC battery charger. Audio is provided by a Realtek ALC5650 codec, and thermal monitoring is managed by a TMP432 sensor. The board also integrates a REALTEK audio codec in a QFN-48 package and supports a WLAN/BT combo module.
