Application Specific Microcontrollers Procurement Notes

Verify the specific suffix QFP indicates the quad flat package variant when sourcing. Confirm that the manufacturer designation aligns with Standard Microsystems Corporation (SMSC) or its successor entities. Ensure the datasheet matches the Enhanced Super I/O specification rather than generic interface controllers. Check for any regional compliance certifications required for your target market deployment.

Application Specific Microcontrollers Selection Notes

Select this component when a unified solution for legacy I/O management is required without separate discrete chips. Consider it for designs needing integrated infrared support alongside standard serial and parallel connections. Evaluate pin count and package size constraints against available PCB real estate. Compare power consumption profiles against newer generations if energy efficiency is a primary design driver.

Application Specific Microcontrollers Part Context

This part belongs to the FDC37M series of Super I/O controllers from SMSC. These chips were widely used in the late 1990s and early 2000s for PC architecture. The series typically combines keyboard, mouse, parallel, and serial controllers into one IC. This specific model emphasizes compatibility with Japanese PC standards like PC98.

Application Specific Microcontrollers Replacement Considerations

Check for direct cross-reference codes from Microchip Technology, which acquired SMSC assets. Verify pin-to-pin compatibility with FDC37C93x series variants if upgrading. Ensure software drivers support the specific register set of the M813 variant before substitution.
