Technical Specifications
Technical Summary
This HuaQin S750-13 motherboard schematic, project NB2857 REV1.0 dated December 8, 2020, is built on the AMD Renoir platform with LPDDR4x memory architecture supporting dual-channel 4266MT/s via CHA and CHB. The embedded controller is an IT8987VG/BX with SHD SPI programming capability. The system BIOS is stored on a SPI ROM. Audio is handled by an ALC3306 codec. The sensor hub and card reader functions are integrated into an IT81201. USB-C connectivity is managed by a CCTUSB1044 hub controller, and USB-C CC OVP is provided by TPD6S300A devices. The block diagram also references an AMD Cezanne platform alias.
