TMC2255R1C1

Overview

The TMC2255R1C1 is a specialized integrated circuit manufactured by Fairchild Semiconductor, classified under Specialized ICs. It functions as a convolver, designed for signal processing applications requiring convolution operations. The device is housed in a 68-PLCC (Leadless Ceramic Chip Carrier) package with J-leads, measuring 24.23x24.23 mm. It supports surface mount mounting types and is supplied in bulk packaging. This component is part of the broader semiconductor portfolio focused on specialized interface and processing solutions.

Feature Summary

• Integrated convolver function for digital signal processing
• 68-pin PLCC package with J-lead configuration
• Surface mount technology compatible
• Bulk packaging format

Applications

• Digital signal processing systems
• Specialized communication equipment
• Industrial control interfaces

Procurement Notes

Verify the manufacturer designation, as Fairchild Semiconductor has undergone corporate restructuring and integration into ON Semiconductor. Confirm the specific lot date code and authenticity through authorized distribution channels. Ensure the bulk packaging condition meets storage and handling requirements for leaded ceramic packages.

Selection Notes

Select this component when a dedicated hardware convolver is required for real-time signal processing tasks. The 68-PLCC package offers a compact footprint suitable for dense PCB layouts. Consider thermal management and board space constraints associated with the 24.23x24.23 mm dimensions during the design phase.

Part Context

This part belongs to the category of specialized interface and processing ICs. Convolver ICs are typically used in applications involving correlation, pattern matching, or specific mathematical transformations in the time domain. The PLCC package style indicates an older generation surface mount technology, often found in established industrial or telecommunications designs.

Replacement Considerations

Check for updated part numbers under ON Semiconductor branding due to corporate integration. Verify pin-to-pin compatibility if substituting with other 68-PLCC convolvers or general-purpose DSPs. Ensure the replacement supports the same voltage levels and signal integrity requirements.
