Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GCGFB#50 | Same 128 KB/8 KB/12 KB memory, identical pinout, but rated for -40°C to +85°C (D-grade) instead of +105°C. | Suitable for consumer or indoor industrial use where ambient temperature stays below 85°C. | Select when cost optimization is prioritized and extended temperature is unnecessary. |
| R5F101GCDFB#50 | Same package and pinout, but lacks data flash memory (0 KB); retains full code flash and RAM. | Applicable where nonvolatile parameter storage is handled externally or not required. | Choose when firmware-only storage suffices and data flash BGO functionality is unused. |
Compared with R5F100GCDFB#50, R5F100GCGFB#50 trades industrial temperature margin for lower unit cost, while R5F101GCDFB#50 eliminates data flash to reduce silicon area-both retain identical peripheral sets and real-time capabilities for drop-in layout reuse where thermal or storage requirements align.
