FW82801FR

The FW82801FR provides extensive I/O support.Functions and capabilities of FW82801FR include:(1)PCI Rev 2.2 compliant with support for 33 MHz PCI operations;(2)PCI slots support up to four Req/Gnt pairs;(3)enhanced DMA controller,interrupt controller,and timer functions;(4)integrated IDE controller supports Ultra ATA100/66/33;(5)USB host interface with support for two USB ports;one host controller;(6)two integrated LAN controllers;(7)low pin count (LPC) interface;(8)firmware Hub (FWH) interface support;(9)serial I/O unit containing two UARTs.

The absolute maximum ratings of the FW82801FR can be summarized as:(1)case temperature under bias:0º C to +109º C;(2)storage temperature:-55º C to +150º C;(3)voltage on any 3.3 V pin with respect to ground:-0.5 to Vcc + 0.3 V;(4)voltage on any 5 V tolerant pin with respect to ground:-0.5 to Vref+0.3 V;(5)1.8 V supply voltage with respect to Vss:-0.5 to +2.7V;(6)3.3 V supply voltage with respect to Vss:-0.5 to +4.6 V;(7)5.0 V supply voltage (Vref) with respect to Vss:-0.5 to +5.5 V;(8)maximum power dissipation:2.0 W.All of the AC and DC characteristics specified in this document assume that the FW82801FR component is operating within the Functional operating range given in this section.Operation outside of the functional operating range is not recommended,and extended exposure outside of the functional operating range may affect component reliability.
