Sony MBX-215 MBX-235 Foxconn M931 Rev SA Schematic
Technical Specifications
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. Discrete graphics is provided by an nVIDIA N11P-GE1-A3 or N11M-GE1-A3 dGPU with DDR3 VRAM configurations of 64Mx16bitx8 or 64Mx16bitx4. System management is handled by a Winbond NPCE783L EC/KBC with dedicated 1Mbit SPI firmware, while the system BIOS resides on a 32Mbit SPI flash. The audio subsystem uses a Realtek ALC275-A5 codec, and networking is via a Marvell 88E8057 GbE controller. Power management includes a BQ24753 charger IC and multiple DC/DC converters from Maxim, Texas Instruments, and Semtech. Memory is supported via two DDR3 SO-DIMM slots.
