CS82C54-10

Overview

The CS82C54-10 is a high-performance CMOS programmable interval timer manufactured by Renesas Electronics Corporation. It features three independent 16-bit counters 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 consumes 10mA at maximum frequency. It utilizes an advanced 2-micron CMOS process for low power operation while maintaining performance comparable to NMOS equivalents. The component is housed in a 28-PLCC package and supports binary or BCD counting modes.

Feature Summary

• Three independent 16-bit programmable counters
• Maximum clock frequency of 10MHz
• Single 5V power supply (4.5V to 5.5V)
• CMOS output type with 10mA operating current

Applications

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

Part Context

The CS82C54-10 belongs to the 82C54 series, which serves as an enhanced CMOS version of the NMOS 8253. It is designed to be fully TTL compatible and compatible with industry-standard microprocessors such as the Intel 80C86, 80C88, and 80C286. The '10' suffix denotes the 10MHz speed grade variant within the family.

Replacement Considerations

Compatible replacements include other 82C54 variants from Renesas or Intersil, such as the IS82C54-10Z or CS82C54-10Z, provided the package type (PLCC-28) and speed grade match. Verify pinout compatibility when substituting with NMOS 8254 derivatives.
