Microcontrollers Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified suppliers. Confirm that the specific suffix matches the required package and temperature grade. Check for recent Product Change Notices regarding manufacturing site updates or material changes. Ensure compliance with RoHS3 directives as indicated in official documentation. Validate supply chain integrity due to the product's end-of-life status.

Microcontrollers Selection Notes

Evaluate the 16MHz clock speed against application timing requirements. Assess whether the 32KB Flash capacity meets firmware size constraints. Consider the 2K RAM limit for variable storage needs. Verify compatibility with the 3V to 5.5V power supply range. Confirm that the 64-pin LQFP footprint fits the target PCB layout. Review peripheral availability for necessary I/O and communication functions.

Microcontrollers Part Context

This component belongs to the H8/300H Tiny family, designed for cost-sensitive applications needing 16-bit performance. It shares architectural similarities with other members like the HD64F3664 series but differs in package and specific pinout configurations. The H8/300H architecture emphasizes high code density and efficient interrupt handling for real-time control environments.

Microcontrollers Replacement Considerations

Consult the H8/3664 Group Hardware Manual for compatible alternatives within the same family. Verify pin-to-pin compatibility before substituting with variants such as the HD64F3664 series. Ensure functional equivalence in memory size and peripheral sets. Cross-reference datasheets for any differences in electrical characteristics or operating temperatures.
