Technical Summary

The Quanta Butternut (NM9) motherboard is built around the AMD Ontario APU platform paired with the HUDSON-M1 Fusion Controller Hub. System memory consists of two DDR3 SO-DIMM slots supporting up to 4GB each in a single-channel configuration at 1333MT/s. The embedded controller is an IT8518, and the audio codec is an ALC269 HD Audio. Wired networking is handled by a Realtek RTL8111E Gigabit LAN controller. The charging architecture uses an OZ8681 battery charger IC, with system power managed by RT8228AZ, RT8223, OZ8380, RT8207, G5173, and SLG55448VTR regulators. The BIOS is stored on a SPI Flash device. The board also integrates an AZALIA HD Audio interface, GB MAC, SATA III, USB 2.0, LPC, and PCIe Gen1 interfaces.
