Technical Specifications
Technical Summary
The Quanta Computer FM9B3A motherboard, revision 3A, dated October 5, 2009, is built around the Clarksfield/Auburndale CPU platform with an rPGA 989 socket and an Intel HM55 PCH. Graphics are handled by Intel UMA. The system uses an ITE8502 EC/KBC and features a 4Mbyte SPI flash for BIOS. Memory architecture consists of dual-channel DDR3 800/1066 1.5V across two SODIMM slots. Power management includes a MAX8731 charger and multiple regulators such as the TPS51427A, MAX17028, TPS51116, TPS51218, and MAX17036. The audio codec is a 92HD73C, networking is provided by an RTL8111DL LAN IC, and the system includes an R5U230 card reader controller. HDMI level shifting is handled by a PI3VDP411LSZ, and USB signal switching uses an SN75LVCP412. Thermal monitoring is managed by an SMSC1422 sensor, and clock generation is provided by an LG8SP585VTR in a QFN-32 package.
