Product details
Overview
R5F100GAAFB#50 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), and real-time clock with calendar support - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100GAAFB#50 datasheet, R5F100GAAFB#50 pinout, R5F100GAAFB#50 application, or R5F100GAAFB#50 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), on-chip debug capability, self-programming flash with boot swap, and hardware DMA supporting concurrent background data flash rewriting.
Technical Context
The R5F100GAAFB#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2–4× UART/LIN interfaces, 2–8× CSI/SPI channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all accessible via configurable GPIO with N-ch open-drain, TTL input, and pull-up options across 48 pins.
