Overview
The COP8ACC720M8-RE is an 8-bit microcontroller from the National Semiconductor COP8™ 8A series. It features a 4KB (4K x 8) One-Time Programmable (OTP) memory capacity and operates with a clock frequency of up to 4MHz. The device is housed in a 20-SOIC package and utilizes CMOS technology. It integrates the COP800 CPU core, providing embedded control capabilities for dedicated applications requiring non-volatile program storage without the need for external memory components.
Feature Summary
- Integrates 4KB OTP memory for permanent program storage
- Utilizes the COP800 CPU architecture for efficient processing
- Operates on CMOS technology within a compact 20-SOIC package
Applications
- Embedded control systems requiring fixed firmware
- Consumer electronics with single-use programming needs
- Industrial automation controllers with limited I/O requirements
Procurement Notes
Verify the specific suffix designation against official National Semiconductor documentation to confirm pinout compatibility and electrical characteristics. Ensure that the OTP nature of the device aligns with production volume requirements, as reprogramming is not possible after fabrication. Confirm RoHS compliance status through current manufacturer declarations rather than distributor listings.
Selection Notes
Select this component when a cost-effective, single-programming microcontroller solution is required for low-volume or prototype runs. Consider the 4MHz operational speed and 20-pin form factor against available alternative packages. Evaluate the COP800 instruction set compatibility with existing development tools before finalizing the design choice.
Part Context
This part belongs to the COP8 family, known for its robust performance in dedicated control applications. The COP8™ 8A series represents an evolution in the line, offering improved integration and reliability. National Semiconductor, now part of Texas Instruments, originally developed this architecture for high-volume consumer and industrial markets.
Replacement Considerations
Direct substitutes include COP8ACC720M9-RE and COP8ACC720M8-XE. Verify pin-to-pin compatibility and software compatibility before substitution. Cross-reference datasheets to ensure identical memory size and package dimensions.
