Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104JGAFA#V0 | Same 52-pin LQFP package, but 256 KB flash / 24 KB RAM / 8 KB data flash; higher memory density. | Better suited for applications requiring larger firmware (e.g., multi-protocol gateways or OTA update buffers). | Select when future firmware growth or dual-bank bootloading is required; identical pinout and peripheral set. |
| R5F104JHAFB#V0 | Same flash/RAM/data flash specs, but 48-pin LFQFP (7×7 mm, 0.5 mm pitch); smaller footprint, fewer I/Os (42 vs 46 GPIO). | Preferred for space-constrained designs where I/O count and package height are critical (e.g., portable medical devices). | Choose for PCB area reduction; verify I/O mapping compatibility-some pins (e.g., P76, P77) are absent in 48-pin variant. |
