Microprocessors Procurement Notes

Verify the specific package variant and manufacturing date code upon receipt to ensure compatibility with existing board layouts. Confirm RoHS compliance status as indicated in official documentation, noting that some variants may not meet current environmental standards. Cross-reference the full part number including suffixes to match exact electrical and mechanical specifications required for the design.

Microprocessors Selection Notes

Select this component when an 8-bit architecture with high-speed 20 MHz operation is required. Ensure the application can accommodate the LCC-84 surface mount package dimensions. Verify that the 20-bit address space meets memory addressing needs and that the available I/O lines suffice for peripheral connections without additional multiplexing.

Microprocessors Part Context

This microprocessor belongs to the Hitachi/Renesas HD64180 family, designed for robust 8-bit processing tasks. It represents a transition point in the series offering higher clock speeds compared to earlier models while maintaining compatibility with established development tools and software ecosystems used in legacy and modern industrial applications.

Microprocessors Replacement Considerations

Consult official Renesas documentation for direct pin-compatible substitutes within the same family. Verify electrical characteristics and package dimensions before swapping with other 8-bit microprocessors from different manufacturers.
