Technical Specifications
Technical Summary
The Quanta BF1 motherboard is designed around the Intel Northwood CPU platform in a Micro-FCPGA socket, paired with the Montara-GML GMCH in a 732 uFCBGA package and the ICH4-M southbridge in a 421 BGA package. System memory consists of two DDR SDRAM 2.5V SO-DIMM slots. The embedded controller is a PC8739366 Super I/O in a 100-pin TQFP package. Audio is handled by an AC97 CODEC with a TPA0312 audio amplifier. Networking is provided by a BCM5901KFB LAN controller in a 176-pin LQFP package. The clocking solution uses a CK-408 ICS950810 clock generator. A PCI1410A or OZ6912 CardBus controller in a 478-pin package manages the CardBus slot. Thermal monitoring is performed by a G768B sensor. The system includes a dedicated battery charger circuit.
