Microcontrollers Procurement Notes

Verify the specific suffix 'DV' against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the H8/300L family. Confirm end-of-life status and lead times with authorized distributors, as this component may be discontinued or subject to limited availability. Ensure compatibility with existing PCB footprints for the 80-TQFP package before procurement.

Microcontrollers Selection Notes

Select this component when a cost-effective 8-bit solution with integrated OTP memory is required. It is suitable for applications needing moderate processing speed up to 8MHz and multiple analog input channels. Consider the 80-TQFP package size constraints and the -20°C to 75°C operating temperature range during design integration.

Microcontrollers Part Context

This part belongs to the H8/300L SLP series, designed for low-power and high-performance embedded applications. The H8 architecture provides efficient instruction execution for 8-bit operations. This specific model utilizes OTP technology, making it ideal for mass production where reprogramming is not required after initial flashing.

Microcontrollers Replacement Considerations

Consult Renesas cross-reference tools for electrically compatible alternatives. Verify that any substitute maintains the same 80-TQFP footprint and pin configuration. Ensure the replacement supports similar memory sizes and peripheral sets like SCI and A/D converters.
