Microcontrollers Procurement Notes

Verify the specific suffix #20 against the official Renesas RX71M Group Datasheet to confirm package type and temperature grade. Confirm current production status as some RX71M variants have reached end-of-life. Ensure design-in compatibility with existing PCB footprints for the 100-pin TFLGA format before procurement.

Microcontrollers Selection Notes

Select this component when a balance of moderate pin count and high processing speed is required. The 2.5MB flash capacity suits complex firmware applications without excessive cost. Compare against other RX71M members like the R5F571MLCDFB#V0 if higher I/O counts or larger memory are needed.

Microcontrollers Part Context

This part belongs to the RX71M group, designed for industrial equipment requiring high performance and rich peripheral sets. It shares the RXv2 core lineage with broader RX family devices but offers specific memory and interface configurations tailored for robust embedded control tasks in demanding environments.

Microcontrollers Replacement Considerations

Check for direct pin-compatible substitutes within the RX71M group such as R5F571MLCGFC#H0 or R5F571MGGDLJ#20, verifying memory size differences. Consult the RX Family Part Number Guide for updated availability and cross-reference any discontinued variants.
