FDC92C39BTP

Specialized Overview

The FDC92C39BTP is a multifunction peripheral component manufactured by SMSC, designed for embedded systems requiring integrated control capabilities. It utilizes CMOS technology and operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal rating of 5 V. The device features an 8-bit external data bus and an 11-bit address bus, supporting ISA bus compatibility. It includes eight input/output lines and functions as a single functional unit. The maximum clock frequency (FCLK) is specified at 14.32 MHz. The component is housed in a 100-terminal plastic/epoxy flatpack package with a 0.65 mm pin pitch, utilizing gull-wing terminals for surface mount installation. It supports commercial temperature ranges from 0°C to 70°C.

Specialized Feature Summary

• Integrates multiple peripheral functions into a single CMOS-based chip for system control
• Supports standard ISA bus architecture with dedicated address and data buses
• Designed for surface-mount applications using a 100-pin flatpack configuration

Specialized Applications

• Embedded controller systems requiring multifunction peripheral integration
• ISA bus compatible hardware designs
• Commercial electronic devices operating within standard temperature ranges

Specialized Procurement Notes

Verify the specific suffix 'BTP' against official SMSC documentation to confirm exact package variant and material specifications. Ensure compliance with RoHS directives if required, as historical SMSC components may not meet current standards. Confirm lead time and availability through authorized distributors, as this part may be discontinued or limited in stock.

Specialized Selection Notes

Select this component when an ISA-compatible multifunction peripheral is required for legacy or specialized embedded architectures. Consider the 100-pin flatpack footprint during PCB layout planning. Verify that the 5V logic levels and 14.32 MHz clock speed align with the target system's timing requirements and power constraints.

Specialized Part Context

The FDC92C39 series belongs to SMSC's line of multifunction peripherals, often used in industrial and computing applications before the widespread adoption of more integrated SoCs. These chips typically consolidate functions like parallel ports, serial ports, and timer/counters into a single package to reduce board space and complexity.

Specialized Replacement Considerations

Check for direct cross-references from Microchip Technology, which acquired SMSC's peripheral business. Verify pin-to-pin compatibility with newer multifunction I/O controllers if upgrading to modern packages.
