Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F72625W144FP#U0 | Same SH-2A core and pinout, but with reduced flash (512 KB) and no FPU - lacks IEEE 754 hardware acceleration | Suitable for cost-sensitive non-FPU applications like basic LIN nodes or simple relay controllers | Select only when floating-point computation is handled in software or unnecessary |
| R7F7010233AFP#AA0 | RX600-series 32-bit core, 100 MHz max, 768 KB flash, no FPU - different instruction set and peripheral register map | Better suited for general-purpose industrial control where RTOS compatibility and toolchain maturity are prioritized over raw FPU throughput | Choose for new designs requiring long-term RX ecosystem support and lower power consumption |
Compared with R5S72625W144FP#U0, the R5F72625W144FP#U0 offers identical packaging and footprint but sacrifices FPU and half the flash capacity, making it unsuitable for complex motor control; the R7F7010233AFP#AA0 provides broader middleware support and lower active power but requires full software porting due to architectural differences.
