Microcontrollers Procurement Notes

Verify the specific suffix #10 against official Renesas documentation to confirm packaging details and tape-and-reel specifications. Ensure the LFQFP-64 package dimensions match your PCB footprint requirements. Confirm that the -40°C to +105°C temperature grade aligns with your environmental design constraints before finalizing procurement orders.

Microcontrollers Selection Notes

Select this component when a balance of high memory capacity (384 kB) and rich peripheral sets is required within the RX231 ecosystem. It is suitable for designs needing multiple serial interfaces and analog conversion without exceeding the 54 MHz performance ceiling. Consider alternative pin counts if more or fewer I/O lines are needed compared to the available 43 ports.

Microcontrollers Part Context

This part belongs to the RX231 group, which targets cost-sensitive yet feature-rich embedded applications. The RX231 series is positioned as a successor to older architectures like the H8S/M16C families for new designs. It offers a standardized interface set and code compatibility within the broader RX family, facilitating migration from legacy Renesas microcontrollers.

Microcontrollers Replacement Considerations

For direct replacements within the same series, consider R5F52317BGND#00 or R5F52316CGFM#30, noting differences in package type (WQFN vs LFQFP) and pin count. Verify electrical characteristics and pinout compatibility carefully when substituting between different package variants in the RX231 family.
