CS82C54-10Z96

Overview

The CS82C54-10Z96 is a high-performance CMOS programmable interval timer manufactured by Renesas Electronics Corporation. It features three independent 16-bit counters, each capable of handling clock input frequencies up to 10MHz. The device operates on a single +5V power supply with a voltage range of 4.5V to 5.5V and draws 10mA during operation. Designed for low-power applications, it utilizes static CMOS circuitry to minimize energy consumption while maintaining TTL compatibility. The component is housed in a 28-PLCC surface-mount package and supports six programmable counter modes for versatile timing functions.

Feature Summary

• Three independent 16-bit programmable counters
• Maximum clock frequency of 10MHz per counter
• Single +5V power supply operation (4.5V–5.5V)
• Six programmable counter modes including event counting and one-shot
• Fully TTL compatible with industry-standard configuration

Applications

• Event counting and elapsed time indication
• Programmable one-shot pulse generation
• Square wave generation for system clocks
• Compatible with 80C86, 80C88, and 80C286 microprocessors

Procurement Notes

Verify the specific suffix '96' against official Renesas documentation to confirm packaging details and moisture sensitivity level. Ensure the 28-PLCC package variant matches the target PCB footprint. Confirm RoHS compliance status and lead-free annealing requirements prior to procurement.

Selection Notes

Select this model when a 10MHz maximum clock speed is required for precise timing intervals. Compare against the standard 8MHz version if lower power consumption is prioritized over speed. Ensure the design accommodates the 28-PLCC surface-mount package dimensions and thermal requirements for industrial or commercial temperature ranges.

Part Context

This component belongs to the 82C54 family of programmable timers, serving as a CMOS enhancement of the legacy NMOS 8253. It provides backward compatibility with standard microprocessor architectures while offering improved performance and reduced power dissipation through advanced CMOS processing technology.

Replacement Considerations

The IS82C54-10Z is a verified equivalent part number from the same manufacturer series. Verify pinout compatibility and electrical specifications before substitution.
