Technical Specifications
Technical Summary
This motherboard is built on the Intel KBL U42/U22 platform with LPDDR3 memory configured as 2 x32 at 1866MHz supporting 4GB or 8GB. The system BIOS is stored on a 16MB W25Q128FVPIQ SPI flash at U3702. The embedded controller is an MK22FN512VDC12A microcontroller with a separate W25X40CLUXIG SPI flash for EC firmware backup. Audio is handled by a Realtek ALC3269-CG codec. Power management includes a BQ25700RSNR battery charge controller. Wireless connectivity is provided by a Marvell 8897 module supporting WLAN 802.11 a/b/g/n/ac and Bluetooth 4.0. The discrete GPU is a G15W in BGA1168 package. Additional components include an NPCT650ABBWX TPM, SN1608035 thermal sensor, and TS3A27518ERTWR power switch.
