Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range compatibility. Confirm that the NOPB suffix aligns with current RoHS compliance requirements as specified in the datasheet. Ensure that the OTP nature of the memory is accounted for during the design phase, as programming cannot be reversed. Check for any end-of-life notices or obsolescence warnings associated with this specific part number before finalizing procurement plans.

Selection Notes

Select this component when a cost-effective 8-bit solution with OTP flexibility is required. It is suitable for designs needing moderate I/O counts and integrated peripherals like timers and serial interfaces. Consider the package availability and pin count relative to the board layout constraints. Evaluate the power consumption characteristics against the system's battery life requirements, particularly in HALT and IDLE modes.

Part Context

This microcontroller belongs to the COP8SA family, which serves as a superserset to the older COP800 family. It maintains pin and instruction set compatibility while adding advanced features such as low EMI capabilities and smaller packaging options. The family is designed for applications where system cost and board space are critical factors, offering a balance of performance and integration.

Replacement Considerations

COP8SAA716M9 is a windowed EPROM version available in the same family.
