CP82C54-10

Overview

The CP82C54-10 is a CMOS programmable timer manufactured by Renesas Electronics. It features three independent 16-bit counters capable of handling clock input frequencies up to 10 MHz. The device operates on a single 5V power supply with a voltage range of 4.5 V to 5.5 V. It supports six programmable counter modes and includes status read-back commands. The component is housed in a 24-pin DIP package and is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Three independent 16-bit programmable counters
• Maximum clock frequency of 10 MHz
• Six programmable counter modes including one-shot and square wave generation
• CMOS technology with low power consumption

Applications

• Event counting applications
• Elapsed time indication
• Programmable one-shot pulse generation
• Square wave frequency generation

Procurement Notes

Verify the specific suffix designation, as public records indicate 'CP82C54-10Z' or 'CP82C54-1096'. Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to ordering. Check for end-of-life notifications or discontinuation notices from the manufacturer to ensure long-term availability.

Selection Notes

Select this component when a 10 MHz maximum clock speed is required for timing functions. Ensure the design accommodates the 24-pin DIP package footprint. Verify that the operating environment falls within the -40°C to +85°C industrial temperature range. Compare against the standard 8MHz variant if lower power consumption is prioritized over speed.

Part Context

This part belongs to the 82C54 family of high-performance CMOS programmable interval timers. It serves as an enhanced version of the NMOS 8253, offering full TTL compatibility and static CMOS operation. The series is designed for compatibility with industry-standard microprocessors such as the Intel 80C86 and 80C286.

Replacement Considerations

Public data lists CA82C5410IN, LN82C542, MSM82C532JS, and MSM82C542JS as cross-reference matches. Verify pinout and electrical specifications before substituting.
