CS82C54-12Z96

Overview

The CS82C54-12Z96 is a CMOS programmable interval timer manufactured by Renesas Electronics Corporation. It integrates three independent 16-bit counters, each capable of handling clock input frequencies up to 12MHz. The device operates on a single 5V power supply with a voltage range of 4.5V to 5.5V. It features six programmable counter modes and supports binary or BCD counting. The component utilizes static CMOS circuit design for low power consumption and is fully TTL compatible. It is housed in a PLCC-28 package.

Feature Summary

• Three independent 16-bit programmable counters
• Maximum clock frequency of 12MHz
• Six programmable timer modes including event counter and one-shot
• CMOS output type with 2.5mA drive capability

Applications

• Event counting
• Elapsed time indication
• Programmable one-shot generation
• System timing control

Procurement Notes

Verify the exact suffix '96' against official Renesas documentation, as standard listings typically use 'Z' for anneal or 'Z96' for industrial temperature variants. Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to ordering. Check current lifecycle status, as older 82C54 derivatives may be discontinued or subject to long lead times.

Selection Notes

Select this model when a 12MHz maximum clock speed is required for precise timing applications. Ensure the system environment remains within the commercial temperature range of 0°C to +70°C. For industrial temperature ranges (-40°C to +85°C), consider the IS82C54Z96 variant instead. Verify that the PLCC-28 surface mount package fits the PCB layout constraints.

Part Context

This component belongs to the 82C54 series of high-performance CMOS programmable interval timers. It serves as an enhanced version of the NMOS 8253, offering lower power consumption while maintaining compatibility with industry-standard microprocessors such as the Intel 80C86 and 80C286 families.

Replacement Considerations

For industrial temperature requirements, the IS82C54Z96 is a verified alternative with a -40°C to +85°C range. The CS82C54-10Z offers a 10MHz limit. Direct pin-compatible replacements from other manufacturers should be verified for electrical parameter alignment.
