Microsoft Surface Pro 3 X896238-001 Schematic
Technical Specifications
Technical Summary
The Pegatron CASTLE2 motherboard, revision 1.02 dated July 8, 2014, is engineered around an Intel Broadwell processor platform. The system EC is an ITE 8528, with its firmware stored on an MX25L4006EZNI-12G EEPROM. The main UEFI BIOS is stored on a 16MB SPI ROM, using either a W25Q128FVSIQ or W25Q128FVPIQ IC. System memory consists of 4GB or 8GB of LPDDR3 at 1600MHz, configured as two x32 IB DRAM packages. Audio is handled by a Realtek ALC3264 codec, and battery charging is managed by a BQ24735 controller. Wireless connectivity is provided by a Marvell 8897 module supporting 802.11 a/b/g/n/ac and Bluetooth 4.0. The board includes a Realtek RTS5304 Micro SD card controller, an ATUC128L3U-Z3UR sensor aggregator microcontroller, and an ATECC108 authentication IC. Thermal monitoring is performed by STTS751-1DP3F sensors, and the board features an ST LSM330 accelerometer and gyroscope, a MEMSIC MMC34160PJ e-compass, and an Intersil ISL29033 ambient light and proximity sensor.
Technician FAQ
Q: What BIOS IC models are used on this motherboard?
A: The main UEFI BIOS is stored on a 16MB SPI ROM, using either a W25Q128FVSIQ or W25Q128FVPIQ.
Q: What EC/KBC is used and is it programmable?
A: The system EC is an ITE 8528. The EC firmware is stored on a separate MX25L4006EZNI-12G EEPROM, and the block diagram indicates an EC Debug UART and SAM SPI reflash capability, supporting programming.
Q: What is the charging IC on this motherboard?
A: The battery charge controller is a BQ24735.
