Technical Summary
This Intel KBL U42 platform motherboard features an Intel processor with LPDDR3 memory down configuration of 4GB or 8GB in 2x32 architecture at 1866MHz. The system BIOS is stored on a W25Q128FVPIQ 16MB SPI flash, while the EC/KBC firmware resides on a separate W25X40CLUXIG EEPROM. The embedded controller is an MK22FN512VDC12 microcontroller. Audio is handled by a Realtek ALC3269-CG codec paired with an ALC1304 speaker amplifier. Charging is managed by a BQ25700RSNR battery charge controller supporting an 18Wh battery. Wireless connectivity is provided by a Marvell 8897 module supporting 802.11/b/g/n/ac and Bluetooth 4.0. The board includes a GL9755 card reader, a TS3A27518ERTWR USB hub, and an NPCT650ABBWX TPM. Sensor aggregation includes a Bosch BMI160 accelerometer and gyroscope, a MEMSIC MMC3530KJ magnetometer, an Intersil ISL29033 ambient light and proximity sensor, and two ROHM BU52058GWZ-E2 Hall effect sensors. Authentication is handled by an ATECC508A cryptographic co-processor.
