Lenovo ThinkCentre M75Q-1 AM4KIH Schematic
Technical Specifications
Technical Summary
The LITE-ON KC792A01 motherboard, revision C1, is designed for the Lenovo M75q-1 Tiny5 AMD platform. It features an AM4 uPGA-1331 socket supporting AMD 35W APUs including Bristol Ridge, Raven Ridge, and Picasso/Athlon, with an AMD Knoll PCH. The board utilizes two DDR4 SO-DIMM slots supporting up to 3200 MT/s. Power delivery is managed by a complex array of ICs including the Intersil ISL62773A, RT8207MGQW, RT6576DGQW, and NCP1589LMNTWG. The system firmware is stored on two SPI flash ROMs: an 8MB IC at 3.3V and a 16MB IC at 1.8V. The embedded controller is an ITE IT8738E Super I/O, while audio is handled by a Realtek ALC222 codec. Networking is provided by a Realtek RTL8111EPV Gigabit LAN controller, and a M.2 2230 slot supports WiFi/BT. A GENESYS GL852G-MNY50 USB hub and a TI HD3SS3220 USB-C controller are also present, along with a Nuvoton NPCT750LABYX TPM module.
