Technical Specifications
Technical Summary
The Wistron Janus HSW 40/50/70X02 motherboard, documented under PCB P/N 13302-1 and project code 4PD00I010001, is a Broadwell-ULT platform design supporting both UMA-only and discrete NVIDIA N15V-GM-S-A2 OPTIMUS graphics configurations. The system utilizes an NPCE285P embedded controller and an ALC3234 high-definition audio codec. BIOS storage is provided by an 8MB Quad Read SPI flash. Power management is handled by a combination of ISL95813HRZ-GP, TPS51225RUKR-GP, and RT8237CZQW-2-GP regulators, with battery charging managed by an HPA02224RGRR-1-GP IC. Memory architecture consists of DDR3L SODIMM modules. The board features dual LAN controller options with RTL8106E for 10/100 and RTL8111G for 10/100/1000, an RTS5170 card reader, and an RTD2168 DP/VGA converter for HDMI level shifting. Wireless connectivity is provided by an 802.11a/b/g/n BT V4.0 combo module.
