CP82C54Z

Overview

The CP82C54Z is a programmable timer integrated circuit manufactured by Renesas Electronics Corporation. It features one internal 16-bit timer with CMOS output capabilities and a maximum propagation delay of 150 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 8 MHz. Designed for surface-mount installation, it is housed in a 24-pin PDIP package. The component functions within an operating temperature range of 0°C to +70°C and draws a typical working power current of 10 mA.

Feature Summary

• Single 16-bit programmable timer channel
• CMOS output type with 150 ns max propagation delay
• Operates on 4.5 V to 5.5 V supply voltage
• Housed in a 24-pin PDIP package

Applications

• Peripheral programmable counter circuits
• Clock and timer IC subsystems
• Industrial control timing applications

Procurement Notes

Verify the end-of-life status before procurement, as the manufacturer has issued discontinuation notifications for this part number. Confirm that the 24-pin PDIP package aligns with existing PCB footprints. Check for moisture sensitivity requirements during storage and handling. Ensure the commercial temperature range (0°C to +70°C) meets system environmental specifications. Validate compatibility with existing 5V logic levels.

Selection Notes

Select the IS82C54Z96 or CS82C54Z96 if three timer channels are required instead of one. Consider the IS82C54-10Z for designs needing a higher 10 MHz clock speed. Choose PLCC packages if surface-mount density is prioritized over through-hole mounting. Verify that the 150 ns propagation delay is sufficient for the target application's timing constraints.

Part Context

This component belongs to the CP82C54 series, which serves as a CMOS-compatible replacement for legacy NMOS timers. It provides functional equivalence to standard industry timer architectures while utilizing advanced CMOS processes for lower power consumption. The part is categorized under Clock & Timer ICs within the broader peripheral programmable counter product line.

Replacement Considerations

Public documentation indicates the CP82C54Z is obsolete. Potential substitutes include the IS82C54Z96 (3-channel, PLCC-28) or CS82C54Z96 (3-channel, PLCC-28). These alternatives offer increased functionality but require package adaptation.
