Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'XE' corresponds to the required temperature grade and packaging variant. Check current product status as legacy components may be obsolete. Ensure compatibility with existing design specifications before procurement.

Selection Notes

Select this part when an 8-bit architecture with OTP storage is required. Consider the 4MHz operational speed and 20-pin SOIC footprint for board layout. Evaluate the 2.7V to 5.5V operating range against system power constraints. Verify that the industrial temperature range meets environmental requirements.

Part Context

This component belongs to the COP8 series, designed for cost-sensitive embedded applications. It utilizes the COP800 CPU architecture. The device is manufactured by National Semiconductor, which is now part of Texas Instruments. The COP8 family is known for its simplicity and low power consumption in dedicated control tasks.

Replacement Considerations

Check for compatible parts such as COP8ACC720M9-XE or COP8ACC720N8-RE. Verify pinout and memory size compatibility. Confirm if alternative packages are available. Review datasheets for functional equivalence.
