Core specs and memory budget for a 16-bit control loop
The R5F100FEGFP#30 is a 16-bit RL78/G13 MCU running at 32 MHz — enough throughput for sensor fusion, motor commutation loops, or Modbus polling without a cache. The 64 KB on-chip flash (64K x 8) and 4 KB RAM leave room for a modest RTOS and a few hundred lines of application code; the separate 4 KB EEPROM array holds calibration constants or boot parameters without wearing the flash.
Industrial temperature grade and peripheral set
On the connectivity side, the MCU integrates CSI (clocked serial), I²C, LINbus, and UART/USART interfaces — enough to talk to an external ADC, a CAN transceiver via LIN, or a serial EEPROM. The 10-channel ADC with 8- or 10-bit resolution samples analog inputs like thermistors or potentiometers without an external converter.
Lifecycle and compliance posture
ROHS3 compliant per the supplier declaration, which covers the ten restricted substances plus the four phthalates. No official second-source or pin-compatible cross-reference is listed; the RL78/G13 family is single-sourced from Renesas.
