Technical Specifications
Technical Summary
This LCFC Serval/Tiger AMD Gen2 motherboard schematic, revision 0.1 dated February 24, 2021, is built around an AMD Gen2 CPU platform with integrated Radeon graphics supporting eDP and HDMI output. Memory architecture consists of LPDDR4X configured in dual-channel CHA and CHB. The embedded controller is an IT5679 located on page P040. SPI ROM and TPM are managed on page P019. Charging is handled by a dedicated charger IC on page P048, with a comprehensive power delivery system including CPU power controller, system DCDC, 3VALW, 5VALW, memory power, ACIN, and DCIN/OTP/RTC rails. Audio is provided by a codec on page P032, networking by a LAN chipset on page P036, and wireless by a WLAN module on page P034. The design includes a USB hub, HDMI retimer, SSD support, thermal monitoring, and a Type-C redriver configuration.
