Most Current Data Sheet To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at: http://www.microchip.com You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page. The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000). Errata An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision of silicon and revision of document to which it applies. To determine if an errata sheet exists for a particular device, please check with one of the following: • Microchip’s Worldwide Web site; http://www.microchip.com • Your local Microchip sales office (see last page) When contacting a sales office, please specify which device, revision of silicon and data sheet (include -literature number) you are using.

SCH3223 1.0 INTRODUCTION 1.1 General Description The SCH3223 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant Super I/O controller with an LPC interface. The SCH3223 also includes Hardware Monitoring capabilities, enhanced Security features, Power Control logic and Motherboard Glue logic. The SCH3223 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. The SCH3223 supports the ISA Plug-and-Play Standard register set (Version 1.0a). The I/O Address and hardware IRQ of each Logical Device may be reprogrammed through the internal configuration registers. There are up to 480 I/O address location options, and a Serialized IRQ interface. 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. They both have the full 8 pin interface. The Serial Ports contain programmable direction control, which will automatically drive nRTS when the Output Buffer is loaded, then drive nRTS when the Output Buffer is empty. Hardware Monitoring (HWM) includes support for monitoring an external temperature via thermal diode inputs and an internal sensor for measuring local ambient temperature. Hardware Monitoring 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 has the ability to alert the system to out-of-limit conditions and automatically control the speed of a fan in response. Hardware Monitoring capability also includes voltage monitoring, and it has the ability to alert the system to out-of-limit conditions. There are four analog inputs for monitoring external voltages of +5V, +2.5V, +12V and Vccp (core processor voltage), as well as internal monitoring of the device’s internal VCC, VTR, and VBAT power supplies. SMI and PME Wake outputs are provided to indicate out-of-limit temperature, voltage, and fan speed conditions. Hardware Monitoring features are accessible via the LPC bus. The Motherboard Glue logic includes various power management and system logic including generation of nRSMRST, 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. System related functionality, which offers flexibility to the system designer, includes General Purpose I/O control functions, and control of two LED's. 2016 Microchip Technology Inc.
