Product details
Overview
R5F100MHGFB#X0 from Renesas is an RL78/G13 80-pin, 128 KB flash, 12 KB RAM, ultra-low-power 16-bit MCU with integrated RTC, 10-bit ADC (26 channels), and multiple serial interfaces (UART, I²C, CSI) for industrial control and sensor node applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100MHGFB#X0 datasheet, R5F100MHGFB#X0 pinout, R5F100MHGFB#X0 application, or R5F100MHGFB#X0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), LFQFP-80 package (0.5 mm pitch), 32 MHz max CPU speed, 66 μA/MHz active current, and on-chip data flash (8 KB) supporting background rewriting.
Technical Context
The R5F100MHGFB#X0 implements the RL78 CPU core with a 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 ultra-low-speed mode). It integrates dual clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for RTC/watchdog.
Peripherals include 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 1× watchdog timer, 2× DMA channels, 16× UART/LIN-capable serial channels (configurable across UART/CSI/I²C), and 10-bit A/D converter with internal 1.45 V reference and temperature sensor - all accessible within its 80-pin LFQFP footprint.
