Technical Specifications
Technical Summary
The Selek 15" CFL-H motherboard, manufactured by Wistron Corporation under project code Selek CFL-H with board number 18825-1 revision A00, is built around the Intel CFL-H Refresh CPU platform using a BGA1440 package paired with an Intel PCH-H 35 chipset. The board supports both UMA-only and discrete NVIDIA graphics configurations, utilizing either the N18P-G0 (4GB) or N17P-G0-K1 (3GB) GPU with GDDR5 VRAM. System management is handled by a Microchip MEC1418 EC/KBC accessible via eSPI bus, while the BIOS is stored on a 16MB SPI flash ROM. Power management includes an ISL88739A charger IC and a comprehensive array of voltage regulators. Memory architecture consists of two DDR4 SODIMM slots supporting dual-channel operation. The board features an ALC3204 audio codec, RTS5144 card reader, RTL8111H LAN controller, Parade PS8409A HDMI 2.0 redriver, TUSB1046 USB-C multiplexer, and Cypress CCG5C USB-C controller, with
