The
SCH3112/SCH3114/SCH3116 product family is a LPC Super I/O controller that integrates
hardware monitoring capabilities, enhanced security features, Power Control logic
and Motherboard Glue Logic into a single device.
The
SCH3112/SCH3114/SCH3116 product family's HWM capabilities include: temperature
monitoring (two external via diode inputs plus one internal), voltage monitoring
(seven voltages) and programmable automatic FAN control. Three fan tachometer
inputs and three pulse width modulator (PWM) outputs are available.
Motherboard
Glue logic includes various power management and system logic including generation
of nRSMRST, a programmable clock output, and reset generation. The reset generation
includes a watchdog timer which can be used to generate a reset pulse. The width
of this pulse is selectable via an external strapping option.
Traditional
legacy Super I/O functionality includes an 8042 based keyboard and mouse controller;
an IEEE 1284, EPP, and ECP compatible parallel port; multiple serial ports; one
IrDA 1.0 infrared ports; a floppy disk controller with SMSC's true CMOS 765B core
and enhanced digital data separator; and 40 GPIO pins.
The
SCH3112/SCH3114/SCH3116 product family is offered in a small-footprint, low-profile
128 VTQFP package, which is especially useful in small form factor designs. |
