R5F10AGFCLFB#55

R5F10AGFCLFB#55 is a Renesas microcontroller in the RL78 family (R5F10A/GF variant). It’s designed for compact embedded control tasks and combines a 16‑bit RL78 core with on‑chip flash and RAM, plus a range of peripherals (timers, ADC, comparators, and serial interfaces such as UART/SPI/I2C) and I/O. The “#55” and “CLFB” suffixes indicate a specific package, lead‑free variant, and revision; exact memory/peripherals vary by exact device.
Key points:
- Low-power operation with multiple power modes
- Rich on‑chip peripherals and I/O
- Supported by Renesas toolchain (e2 studio, CS+) and a flash programmer
- Documentation available: data sheet, hardware manual, application notes
