Microcontrollers Procurement Notes

Verify the specific suffix M1 against official Renesas documentation to confirm exact manufacturing lot or revision details. Confirm availability status as distribution channels may list this part as obsolete or not recommended for new designs. Ensure compatibility with existing PCB footprints and voltage requirements before procurement.

Microcontrollers Selection Notes

Select this component when a 16-bit MCU with moderate memory capacity is required. Compare against the RL78 family for newer design projects as the 78K0R series may be restricted to existing customers. Verify that the 52-pin LQFP package fits the mechanical constraints and that the 20 MHz speed meets system timing requirements.

Microcontrollers Part Context

This model belongs to the 78K0R/Kx3 group of microcontrollers. This series is generally supported only for customers who have already adopted these products. New designs are typically directed toward the RL78/L1C or RL78/L13 groups by the manufacturer.

Microcontrollers Replacement Considerations

Official substitutes include other members of the 78K0R/Kx3 family such as the UPD78F1144AGB-GAH-AX. For new designs, consider migrating to the RL78/L1C or RL78/L13 series.
