Technical Summary

The Foxconn M931 (MBX-215) is a Calpella platform motherboard designed for Arrandale and Clarksfield processors in a Micro-FCPGA-988A socket, paired with the Ibex Peak-M (PM55-B3) PCH. Graphics are handled by a discrete nVIDIA N11P or N11M GPU (N11P-GE1-A3 / N11M-GE1-A3) with dedicated DDR3 VRAM. System management is provided by a Winbond NPCE783L EC/KBC in a QFP-128 package, programmable via a dedicated 1Mbit SPI EC firmware flash. The system BIOS is stored on a single 32Mbit SPI flash. Audio is managed by a Realtek ALC275-A5 codec, and networking by a Marvell 88E8057 GbE controller. Power management includes a BQ24753 charger IC and multiple DC/DC converters (MAX17030, TPS51218, SN0608098, SC412A, MAX17028, G2998). Memory is supported via two SO-DIMM slots for DDR3. A Ricoh R5U231 card reader and a CK505 SL28748ELC clock generator are also present.
