Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm pinout and package variations. Confirm current lifecycle status as components may be subject to change or discontinuation. Ensure compatibility with existing development tools such as CS+ before procurement. Check for moisture sensitivity labeling if long-term storage is planned.

Microcontrollers Selection Notes

Select this model when 128 kB of program memory is required within the 78K0R family. Consider the 100-pin LFQFP package constraints for PCB layout planning. Evaluate the 20MHz maximum clock speed against real-time processing requirements. Compare against the RL78/L1C group for new designs if advanced low-power features are needed.

Microcontrollers Part Context

This microcontroller is part of the 78K0R/Kx3 group, which is maintained for existing customers rather than new design adoption. Renesas recommends transitioning to the RL78/L1C or RL78/L13 groups for future projects due to architectural advancements. The 78K0R series remains supported for legacy maintenance and continued production runs.

Microcontrollers Replacement Considerations

Consult official substitution lists for direct equivalents. The RL78/L1C and RL78/L13 groups are recommended alternatives for new designs, though they require software migration. Verify pin-to-pin compatibility if replacing within the same package type.
