Technical Specifications
Technical Summary
This Wistron Fonseca 14" UMA motherboard, project code Fonseca UMAX02, board number DF3-1448.4GN01.0 revision 1.0, is built on the Intel Ibex Peak-M platform with a Mobile Arrandale CPU in an rPGA988A socket and an Intel PCH HM55 southbridge. The graphics architecture is UMA. The system uses DDR III memory across two DIMM slots configured as Channel A and Channel B. The embedded controller is a MEC 5045 with an ECE 5028 SIO Expander. The main BIOS is stored on a 64Mb SPI flash, while the LOM flash is 8Mb. The charging architecture is managed by a TI BQ24745 RHDR charger. Power regulation is handled by ADP3211, TPS51125, TPS51218, TPS51116, ISL62883, MAX17036, and RT9018. The audio codec is an IDT92HD81 Azalia CODEC. Networking is provided by a BCM5761E LAN IC and a WLAN module. The card reader IC is an R5U242, and the USB hub IC is a TPS2231 MRGPR. Thermal monitoring uses an EMC4022 sensor, and the HDMI level shifter is a MAX4885EETG.
