Technical Summary

The Wistron V550_TGL-1 motherboard, documented under project codes 13"-4PD0LX010001 and 14"-4PD0LY010001 with PCB P/N 19869 revision -1, is engineered for Intel Tiger LAKE-U 4+2 platforms with a PCH-LP southbridge. The system utilizes LPDDR4X memory down architecture across two channels at 3733MHz. The BIOS is stored on a 32MB SPI Flash ROM managed by the Nuvton NPC386 EC/KBC. Power management is handled by a BQ25710 battery charger/selector and multiple DC/DC converters including TPS51487XRJER, RT5797ALGQW, RT3613EEGQW, TPS51395PRJER, TPS51393PRJER, TPS54302DDCR, RT6543AGQW, and AOZ5516QI. Audio is provided by a Realtek ALC3306 codec with a TAS2770 amplifier. Connectivity includes an Intel Burnside BRIDGE TBT RETIMER for Thunderbolt, PS8409 for HDMI 2.0b re-timing, and PS8719 for USB3.0 re-driving. The board integrates WLAN via CNVi and features a PS21449 fan controller and a Hall sensor for thermal management.
