Product details
Overview
R5F100FEGFP#50 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates UART/LIN, I²C, CSI, 16-bit timers, 10-bit ADC (24 channels), RTC, and operates from 1.6–5.5 V for battery-powered industrial sensors and smart meters.
For engineers reviewing the R5F100FEGFP#50 datasheet, R5F100FEGFP#50 pinout, R5F100FEGFP#50 application, or R5F100FEGFP#50 equivalent, key selection criteria include its 44-pin LQFP package, 96 KB code flash with self-programming, 10-bit 24-channel ADC, LIN-capable UART, and -40°C to +105°C industrial temperature grade (G-suffix).
Technical Context
The R5F100FEGFP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and 1 MB address space. It features dual clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and subsystem clock for RTC/LVD.
Its peripheral set includes 2–4 DMA channels, 8–16 × 16-bit timers, 1 × 12-bit interval timer, 1 × calendar RTC with alarm/correction, 1 × watchdog timer, and 3–10 I²C/Simplified I²C channels - all configurable via dedicated SFRs and interrupt vectors aligned to the RL78 G13 family architecture.
