SIO1036-ZG

Specialized Overview

The SIO1036-ZG is a Super I/O controller manufactured by Microchip Technology (formerly SMSC), designed for PC99 and PC2001 compliant systems. It operates at 3.3V with 5V tolerant inputs and features an LPC bus host interface supporting multiplexed command, address, and data buses. The device integrates a multi-mode parallel port with ChiProtect circuitry, a dedicated serial infrared interface supporting IrDA v1.2, HPSIR, ASKIR, and Consumer IR protocols, and one general-purpose I/O pin. It utilizes Software Configurable Logic for system configuration and supports ISA Plug-and-Play standards.

Specialized Feature Summary

• LPC Bus Host Interface: Supports 8-bit I/O and DMA transfers with 16-bit address qualification and PCI CLKRUN# compatibility.
• Multi-Mode Parallel Port: Compatible with EPP 1.7/1.9 and ECP modes, featuring ChiProtect circuitry to prevent damage from powered printers when unpowered.
• Infrared Communications Controller: Includes a dedicated UART supporting IrDA v1.2 (4Mbps), HPSIR, ASKIR, and Consumer IR formats.
• Software Configurable Logic: Enables programmable configuration of key functions such as the parallel port and UART via internal registers.

Specialized Applications

• PC99 and PC2001 compliant desktop computer systems
• Industrial control applications requiring robust parallel port connectivity
• Devices utilizing consumer infrared remote control interfaces
• Embedded systems needing reduced-pin-count ISA replacement via LPC

Specialized Procurement Notes

Verify the component origin, as the datasheet identifies the manufacturer as SMSC or its subsidiaries, while the input specifies Microchip Technology. Confirm that the -ZG suffix strictly denotes the 36-pin QFN lead-free RoHS compliant package as stated in the ordering information. Ensure the revision level matches the required specification, noting this document is Revision 0.4 Product Preview.

Specialized Selection Notes

Select the SIO1036-ZG for designs requiring a pin-reduced LPC interface to replace legacy ISA controllers. It is suitable for applications needing integrated support for high-speed infrared communication alongside standard parallel port functionality. Consider the 3.3V operation requirement and verify compatibility with the target system's LPC bus signaling levels and clock speeds.

Specialized Part Context

The SIO1036 belongs to the Super I/O controller family developed by Standard Microsystems Corporation (SMSC). These components are designed to consolidate legacy I/O functions into a single chip, reducing board space and complexity. The ZG variant specifically refers to the lead-free, RoHS-compliant version housed in a 36-terminal QFN package.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify electrical compatibility and pinout alignment if considering alternative Super I/O controllers from other manufacturers.
