Technical Summary

The Wistron Cheetah motherboard, revision C1, dated May 19, 2021, is built on the Intel TGL-H platform with DDR4 memory architecture across CH-A and CH-B. The system utilizes an NPCX997KA0BX EC/KBC and features an N19E discrete GPU with dedicated VRAM channels A through D. Audio processing is handled by an ALC3286 codec paired with an ALC1309L smart amplifier. The board includes Thunderbolt retimers A and B, a USB PD controller, an HDMI2.1 retimer, and a discrete TPM 2.0 module. Storage is supported via an M.2 PCIe Gen4 SSD slot, while wireless connectivity is provided by an M.2 1216 module. Power management is distributed across multiple DC/DC converters including IMVP9, VCCPUCORE, VCCGFXCORE, and various voltage rails.
