R5F64175PFB

R5F64175PFB is a Renesas microcontroller in the R5F RL78/R5F family. It is a 16‑bit embedded MCU with on‑chip flash and RAM, designed for compact, low‑power control tasks. The device combines a Renesas 16‑bit CPU core with a range of peripherals common to RL78/R5F parts, such as timers, analog-to-digital converters, comparators, and serial interfaces (SCI/UART, I2C, SPI). It supports low‑power modes and other power-management features for energy‑sensitive applications. The PFB suffix indicates package/temperature options; exact memory sizes and peripherals vary by variant. It provides in‑system programming and debugging via Renesas tools (e2studio or CS+ and Renesas Flash Programmer). Applications include consumer electronics, home appliances, industrial control, and other embedded systems requiring a small footprint and reliable performance. For precise specs, consult the official datasheet for your specific part variant.
