Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104PJAFP#30 | RL78/G13-based; 32 KB Flash, 4 KB RAM, lower power (0.52 μA STOP mode), no complementary PWM | Better suited for ultra-low-power sensing nodes; lacks integrated motor control peripherals | Select when energy efficiency outweighs motor drive capability and code size is constrained |
| UPD78F0537AGC(S)-GAD-M1-AX | Same 78K0/KF2 family; 96 KB Flash, 6 KB RAM, identical pinout and peripheral set except reduced Flash/RAM | Direct drop-in replacement where firmware fits within 96 KB and 6 KB RAM constraints | Choose for cost-sensitive designs retaining full peripheral compatibility and layout reuse |
Compared with UPD78F0547AGC(S)-GAD-M1-AX, R5F104PJAFP#30 offers superior low-power performance but omits complementary PWM and reduces memory - limiting suitability for motor control.
