Dell G3 3590 Wistron Selek CFL-H 18225-1 Schematic
Technical Specifications
Technical Summary
The Selek 15" schematic, revision A00 dated 2019/04/03, is a Wistron Corporation design under project code Selek CFL-H with board number 18825-1. It is built around an Intel CFL-H refresh CPU in a BGA1440 package paired with an Intel PCH PCH-H 35 chipset. The platform supports both UMA-only and discrete NVIDIA Optimus configurations, utilizing either an N18P-G0 (4GB) or N17P-G0-K1 (3GB) GPU with GDDR5 VRAM. System memory consists of two DDR4 SODIMM slots. The embedded controller is a Microchip MEC1418, and the audio codec is an ALC3204. The BIOS is stored on a 16MB SPI flash ROM. Charging is managed by an ISL88739A IC over the DCBATOUT architecture. The board features a Parade PS8409A HDMI 2.0 re-driver, a TUSB1046 USB-C mux and redriver controlled by a Cypress
