Microcontrollers Procurement Notes

Verify the specific suffix #55 against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS3 directives and check moisture sensitivity levels before assembly. Confirm that the LFQFP-48 footprint matches your PCB design requirements. Validate the AEC-Q100 certification status for your target automotive application tier.

Microcontrollers Selection Notes

Select this model when a 16-bit architecture with native CAN support is required within the RL78 family. The 128 kB flash size accommodates moderate firmware complexity. Consider the 32 MHz speed and 2.7 V minimum voltage for power-constrained automotive environments. Compare pin counts and peripheral sets against other RL78/F13 variants if fewer I/Os or different packaging are needed.

Microcontrollers Part Context

This component belongs to the RL78/F13 series, which targets automotive and industrial markets. The series emphasizes energy efficiency and robustness. The R5F10B variant specifically integrates CAN capabilities, distinguishing it from standard general-purpose RL78 models. It shares the core architecture with other members but differs in memory size and peripheral availability.

Microcontrollers Replacement Considerations

Consult the official RL78/F13 cross-reference guide for verified substitutes. Alternative part numbers may vary by package (e.g., QFN vs. LFQFP) or memory capacity. Ensure any replacement maintains the same CAN controller version and AEC-Q100 qualification level.
