ibm thinkpad x40 s note-1.0 mini-sit-final-u rev 2 schematic 1
Technical Specifications
Technical Summary
This Wistron Corporation motherboard (Document Number A3166, dated January 30, 2004) is built around the Intel Banias/Dothan Mobile CPU platform with an Intel ICH4-M southbridge and integrated Motara-GM Plus graphics. The system uses DDR memory via two on-board SODIMM sockets. The EC/KBC is an H8S/2161B, and the BIOS flash is an SST-49LF008F. Power management is handled by a suite of ICs including the MAX1977, MAX1992, MAX1907, MAX1845, MAX8873, and ALP2996MR, with battery charging managed by a MAX1870C charger/selector. Audio is provided by an AD1981B codec. Networking includes both an Intel 82562EZ 10/100 PHY and an Intel 82541EX Gigabit LAN controller, with wireless connectivity via a Mini-PCI 802.11a/b/g slot. The system also features a RICOH R5C5811 Cardbus + SD card controller and an SMSC USB20H04 USB hub.
