Technical Summary

The LC Future Center Drift AMD2 motherboard, revision 1.0, dated April 29, 2019, is built around the AMD2 platform with integrated AMD Radeon Graphics. The system utilizes two DDR4 SODIMM slots for memory expansion. The embedded controller is an IT5261VG, which is programmable via SPI flash, with the EC firmware stored on a Winbond W25Q128JVSIQ SOIC-8 flash IC. The main BIOS/SPI flash is also a Winbond W25Q128JVSIQ, providing 128Mb (16MB) of storage. Audio is handled by a Realtek ALC3287-CG codec, while networking is provided by a Realtek RTL8111H-CG LAN controller and a Realtek RTL8822CE WLAN module. Power management includes a BQ25700A battery charger and multiple DC/DC converters (RT8068A, NB691, TPS51393P, NB693GQ, RT3663BH, NB690, RT8231). The board also features a GL9755 media card controller, a RTS5411 USB hub controller, a RTD2173 HDMI retimer, and a TMP451 thermal sensor.
