Product details

4 KB Flash and 512 B RAM — sizing the firmware footprint

The R5F10267ASM#35: With 4 KB of Flash and 512 bytes of RAM, this MCU is sized for a single-purpose control loop — a fan speed controller, a temperature monitor with one-wire sensor, or a keypad decoder. The 2 KB of EEPROM (2K x 8) is useful for storing calibration constants or configuration parameters that survive a power cycle without external memory. If your firmware image exceeds 4 KB, you need to step up to the RL78/G13 or G14 family with larger Flash options.

Frequently asked questions

What are the alternatives for the R5F10267ASM#35?

The RL78/G14 part R5F104BEGFP#10 offers a 32 MHz core, 25 I/O, and −40°C to 105°C range, but it uses a different package (48-pin LQFP) and is not pin-compatible. Within the RL78/G12 family, the R5F10267ASP#35 is the same silicon in a different tray/tape variant — functionally identical, just a different shipping medium.
