FDC37B772QFP

Application Specific Microcontrollers Overview

The FDC37B772QFP is a multifunction peripheral IC manufactured by SMSC, designed for embedded processor and controller applications. It utilizes CMOS technology and is housed in a 100-pin Quad Flat Package (PQFP) with a 0.65 mm pitch. The device operates within a commercial temperature range of 0 to 70 degrees Celsius and requires a supply voltage between 4.5 V and 5.5 V, with a nominal rating of 5 V. It features an 8-bit external data bus, an 11-bit address bus, and supports ISA bus compatibility. The maximum functional clock frequency is specified at 14.32 MHz.

Application Specific Microcontrollers Procurement Notes

Verify the exact suffix designation against the manufacturer's official documentation to confirm package type and temperature grade. Ensure that the procurement source provides valid traceability for the SMSC brand component. Cross-reference the part number with current active status listings to avoid obsolete inventory. Confirm that the received units match the PQFP-100 physical specifications required for your PCB layout.

Application Specific Microcontrollers Selection Notes

Select this component when an ISA-compatible multifunction peripheral is required for systems operating at standard 5V logic levels. The choice is appropriate for designs needing integrated I/O control without additional discrete logic chips. Consider the 100-pin footprint and thermal characteristics during the initial hardware design phase to ensure adequate board space and heat dissipation capabilities are available.

Application Specific Microcontrollers Part Context

This component belongs to the Super I/O controller family produced by SMSC, which specializes in integrated circuits for data distribution in office and factory environments. These devices typically consolidate legacy interface functions, reducing component count and board complexity in embedded computing architectures that rely on established bus standards for peripheral communication.
