IP82C54

Programmable Timers And Oscillators Overview

The IP82C54 is a high-performance CMOS Programmable Interval Timer manufactured using an advanced 2-micron CMOS process. It integrates three independently programmable and functional 16-bit counters, each capable of handling clock input frequencies up to 8 MHz. The device features six programmable timer modes and operates within a supply voltage range of 4.5 V to 5.5 V. Designed for industrial temperature ranges (-40°C to +85°C), it utilizes a 24-pin CDIP package. Its high-speed operation and industry-standard configuration ensure compatibility with Intersil 80C86, 80C88, and 80C286 CMOS microprocessors.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'IP' against official Renesas documentation to confirm it denotes the industrial grade variant (-40°C to +85°C) rather than commercial or military grades. Confirm RoHS compliance status as datasheets may vary by production lot. Check for end-of-life notices or obsolescence warnings from the manufacturer before procurement planning.

Programmable Timers And Oscillators Selection Notes

Select this component when a CMOS-compatible 8254/8253 replacement is required for 80C86 family processors. Ensure the design supports the 4.5V to 5.5V supply range. Verify that the 24-pin CDIP package fits the PCB layout constraints. Consider the 8 MHz maximum clock frequency limit for timing requirements.

Programmable Timers And Oscillators Part Context

The IP82C54 belongs to the 82C54 series of programmable interval timers. It serves as an enhanced CMOS version of the NMOS 8253, offering higher speed and lower power consumption. The 'I' prefix typically indicates the industrial temperature rating within the Renesas/Intersil product line.
