Procurement Notes
Verify the specific suffix 'V8' against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with existing development tools for the COP8 architecture. Confirm RoHS compliance status as indicated by the NOPB designation in ordering information.
Selection Notes
Select this component when an 8-bit architecture with Flash memory is required for cost-sensitive applications. Consider the 44-pin package size and 38 available I/O lines for system integration. Evaluate the 20 MHz clock speed against processing requirements. Check availability of programming tools for the COP8 family.
Part Context
This part belongs to the COP8 series of 8-bit microcontrollers manufactured by National Semiconductor, now part of Texas Instruments. The COP8 family is known for its low power consumption and integrated peripherals, suitable for standalone control applications. The SD variant typically denotes specific memory and package configurations within the broader product line.
Replacement Considerations
Consult official cross-reference guides for form-fit-function compatible alternatives. Verify pinout and electrical specifications before substituting with other 8-bit microcontrollers.
