Product details
Overview
R5F100FADFP#V0 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates UART, I²C, CSI, 16-bit timers, 10-bit ADC (24 channels), RTC, and operates from 1.6–5.5 V for industrial control and sensor node applications.
For engineers reviewing the R5F100FADFP#V0 datasheet, R5F100FADFP#V0 pinout, R5F100FADFP#V0 application, or R5F100FADFP#V0 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +85°C), integrated data flash with 1M rewrite cycles, background operation during program execution, and support for low-power modes including STOP, HALT, and SNOOZE.
Technical Context
The R5F100FADFP#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and subsystem clock (32.768 kHz).
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, 8 CSI channels, 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar/alarm/correction, and 1× watchdog timer. The 10-bit ADC features internal 1.45 V reference and temperature sensor.
