System related functionality, which offers flexibility to the system designer, is available via General Purpose I/O control functions, control of two LED's, and fan control using fan tachometer inputs and pulse width modulator (PWM) outputs. The SCH5127 is ACPI 1.0/2.0 compatible and therefore supports multiple low power-down modes. It incorporates sophisticated power control circuitry (PCC), which includes support for keyboard and mouse wakeup events. The SCH5127 supports the ISA Plug-and-Play Standard register set (Version 1.0a). The I/O Address, DMA Channel and hardware IRQ of each logical device in the SCH5127 may be reprogrammed through the internal configuration registers. There are up to 480 (960 Parallel Port) I/O address location options, a Serialized IRQ interface, and Three DMA channels. Description The SCH5127 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant Super I/O controller with an LPC interface. SCH5127 also includes Hardware Monitoring capabilities, enhanced Security features, Power Control logic and Motherboard Glue logic. The SCH5127's hardware monitoring capability includes temperature, voltage and fan speed monitoring. It has the ability to alert the system to out-of-limit conditions and automatically control the speeds of multiple fans. There are five analog inputs for monitoring external voltages of +V1_IN (for scaled +12V), V2_IN (for scaled +5V), VTRIP (1.5V), +2.5V and VCCP (core processor voltage), as well as internal monitoring of the SIO's VCC, VTR, and VBAT power supplies. The SCH5127 includes support for monitoring two external temperatures via thermal diode inputs and an internal sensor for measuring ambient temperature. The hardware monitoring block of the SCH5127 is accessible via the LPC Bus. The out-of -limit temperature, voltage of fan tachometer events can be reported on the PME and/or SMI output pin and speaker alarm annunciation. DS00001786A-page 2 2014 Microchip Technology Inc.
