Technical Specifications
Technical Summary
The DW50 motherboard, documented by GFA & WKS Team on 2010.3.10, is built around an Arrandale or Clarksfield CPU platform connected to PCH U2001 via DMI and FDI buses. The system architecture includes GPU U8001, KBC U3701, BIOS SPI flash U6202, and clock chip U701. Power management relies on charging IC TPS51125 and multiple power ICs including PU4504, PU4901, PQ4901, and PQ4504 (N7002). Memory is DDR type configured across Channel A and Channel B DIMM slots. The board integrates USB 2.0 hub functionality, LAN, Bluetooth wireless, and a card reader. The power-on sequence involves S5 voltages generated by TPS51125 under KBC control, with RUNPWROK and VTT_PWRGD signals enabling CPU core voltage VCC_CORE.
