Device Overview

Summary

The SCH3223 is a 3.3V Super I/O Controller with an LPC interface. It includes Hardware Monitoring capabilities, enhanced Security Features, Power Control Logic and Motherboard Glue Logic.  Multiple low power-down modes are supported and sophisticated power control circuitry (PCC) are incorporated, which includes support for keyboard.

Super I/O functionality includes two serial ports.  The serial ports are fully functional NS16550 compatible UARTs that support data rates up to 1.5 Mbps.

Hardware Monitoring (HWM) support for monitoring an external temperature via thermal diode inputs and an internal sensor for measuring local ambient temperature.  HWM also includes programmable, automatic fan control, consisting of a fan tachometer input and a pulse width modulator (PWM) fan control output, responding to temperature inputs and programmable via the LPC bus.  It can alert the system to out-of-limit conditions and automatically control the speed of a fan in response. 

System related functionality, which offers flexibility to the system designer, includes 19 General Purpose I/O (GPIO) control functions. 

The product is available in commercial (0°C to +70°C and industrial (-40°C to +85°C) temperature ranges.
