CS82C54Z96

Overview

The CS82C54Z96 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 8MHz. The device operates on a single 5V power supply with a voltage range of 4.5V to 5.5V and supports six programmable counter modes for applications such as event counting and one-shot generation. It is housed in a 28-PLCC package and is designed for low-power static CMOS operation.

Feature Summary

• Three independent 16-bit programmable counters
• Maximum clock frequency of 8MHz
• Six programmable counter modes including binary or BCD counting
• CMOS output type with propagation delay of 150 ns

Applications

• Event counting
• Elapsed time indication
• Programmable one-shot generation

Procurement Notes

Verify component authenticity through authorized distributors. Check RoHS compliance status and moisture sensitivity level (MSL 3) prior to soldering. Confirm lead times and minimum order quantities directly with suppliers as availability may vary.

Selection Notes

Select the CS82C54Z96 when an 8MHz maximum clock speed is required. Ensure the application environment stays within the commercial temperature range of 0°C to +70°C. Verify that the 28-PLCC surface mount package fits the PCB layout constraints.

Part Context

This part belongs to the 82C54 series of programmable timers. It serves as an enhanced CMOS version of the NMOS 8254, offering lower power consumption while maintaining compatibility with industry-standard processors like the 80C86 and 80C286.

Replacement Considerations

The IS82C54Z96 is a verified substitute part number from the same manufacturer family.
