COP8782CJ

Overview

The COP8782CJ is an 8-bit microcontroller from the National Semiconductor COP8 family, housed in a 28-pin CDIP package. It features 4KB (4K x 8) of One-Time Programmable (OTP) memory for code storage. The device utilizes the COP800 CPU core and operates with an external oscillator type. It is designed for CMOS technology applications.

Feature Summary

• Integrates an 8-bit COP800 CPU core for processing tasks.
• Includes 4KB of OTP memory for non-volatile program storage.
• Supports external oscillator configurations for clock generation.

Applications

• Embedded control systems requiring 8-bit processing
• Industrial automation controllers
• Consumer electronics logic control

Procurement Notes

Verify the specific manufacturer source, as National Semiconductor assets were acquired by Texas Instruments. Confirm the package integrity for the 28-CDIP form factor. Check for RoHS compliance status, as some legacy listings indicate non-compliance. Ensure the OTP memory is suitable for your production volume requirements since it cannot be reprogrammed.

Selection Notes

Select this component when an 8-bit architecture with OTP storage is required. The COP8782CJ offers a balance of processing capability and fixed code storage. Consider the external oscillator requirement for timing precision. Evaluate the 28-CDIP package constraints against your PCB layout needs compared to surface-mount alternatives in the same family.

Part Context

This part belongs to the COP87xx series of single-chip microcontrollers. It shares architectural similarities with other COP8 devices but is distinguished by its specific 4KB OTP capacity and 28-pin DIP packaging. The series is known for robust performance in dedicated control applications using CMOS technology.

Replacement Considerations

Direct substitutes within the COP8 family include parts like COP8720C or COP8721C, though pinouts and memory sizes may differ. Verify compatibility with the COP800 CPU instruction set. Cross-reference with Sanyo LC86P series if pin-compatible alternatives are needed, ensuring functional equivalence in OTP size and I/O configuration.
