CS82C5496S2485

Overview

The Intersil CS82C5496S2485 is a high-performance CMOS programmable interval timer manufactured using an advanced 2-micron CMOS process. It integrates three independent 16-bit counters designed for precise timing and counting applications. The device operates within a supply voltage range of 4.5V to 5.5V and supports clock frequencies up to 12MHz. Packaged in a 28-pin PLCC format, it serves as a versatile solution for generating accurate time intervals without requiring external quartz crystals.

Feature Summary

• Integrates three independent 16-bit counters for simultaneous timing operations
• Eliminates the need for traditional external quartz crystals
• Manufactured using advanced 2-micron CMOS technology for high performance

Applications

• Programmable interval generation
• Frequency division
• Event counting

Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm RoHS compliance status and lead-free specifications against current datasheets. Ensure package integrity matches the 28-PLCC requirement. Cross-reference ordering suffixes with official legacy documentation to confirm functional equivalence before procurement.

Selection Notes

Select this component when three independent 16-bit timers are required in a single package. Verify that the operating environment supports the specified 4.5V to 5.5V supply range. Ensure the system clock frequency does not exceed the 12MHz maximum rating. Consider the 28-PLCC package dimensions for PCB layout compatibility.

Part Context

This part belongs to the 82C54 family of programmable interval timers. Intersil was acquired by Renesas Electronics Corporation, which now manages the product line. The CS82C54 series provides a CMOS-compatible alternative to earlier TTL-based timer designs, offering lower power consumption and higher speed capabilities for modern embedded systems.

Replacement Considerations

Consult Renesas Product Legacy Documents for confirmed substitute part numbers. Verify pinout and electrical parameter compatibility before substitution. No direct public substitutes are listed in available sources.
