The SCH3224I-SY-TR is a 3.3V Super I/O Controller with an LPCinterface. It includes Keyboard Controller, Hardware Monitoring capabilities,Power Control logic, and Motherboard Glue logic. The device provides aparallel port, 4 full serial ports and the option for two additional 4-Pinserial ports. The serial ports are fully functional NS16550 compatibleUARTs that support data rates up to 1.5 Mbps. Hardware Monitoring capability has programmable,automatic fan control. Three fan tachometer inputs and three pulse widthmodulator (PWM) fan control outputs are available. In addition, HWM includestemperature, voltage and fan speed monitoring. It can alert the system toout of limit conditions and automatically control the speed of multiple fans inresponse. System related functionality, which offersflexibility to the system designer, included 40 General Purpose I/O (GPIO)control functions and control of two LED's. The SCH3224I-SY-TR is available in commercial (0°C to+70°C and industrial (-40°C to +85°C) temperature ranges.
