Product details

54 MHz RXv2 core with 128 KB flash — the control-loop ceiling

The R5F52305AGFL#10 is a Renesas RX230 series 32-bit microcontroller built around the RXv2 core, clocked at 54 MHz. The 128 KB on-chip flash and 32 KB RAM leave room for a real-time control loop and a modest communication stack without external memory — the 8 KB data flash (EEPROM emulation) holds calibration constants or boot parameters separately from program space.

Industrial temperature grade and peripheral mix

The 34 GPIOs, 8-channel 12-bit ADC, capacitive touch sensing, and SCI/SPI/I²C serial interfaces fit a human-machine interface or a multi-sensor data concentrator.

Frequently asked questions

What is the closest functional alternative to R5F52305AGFL#10?

The R5F52315AGFL#10 (RX231 series) shares the same RXv2 core at 54 MHz, same flash and RAM, and adds USB OTG connectivity — but drops four I/O (30 vs 34). If USB is not required, the R5F52305AGFL#10 keeps the extra GPIOs. Both are 48-LQFP and pin-compatible in the same footprint.
