Product details
Overview
R5F100MGGFB#X0 from Renesas is an RL78/G13 80-pin, 128 KB flash, 8 KB data 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). It operates from 1.6 V to 5.5 V and delivers 41 DMIPS at 32 MHz, targeting battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100MGGFB#X0 datasheet, R5F100MGGFB#X0 pinout, R5F100MGGFB#X0 application, or R5F100MGGFB#X0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), LFQFP-80 package (0.5 mm pitch), HALT/STOP/SNOOZE low-power modes, and on-chip debug support for rapid firmware iteration in constrained embedded systems.
Technical Context
The R5F100MGGFB#X0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - enabling robust firmware updates and real-time data logging without halting execution.
Peripheral integration includes a 10-bit A/D converter with up to 26 analog inputs and internal 1.45 V reference, dual 16-bit timers with PWM output, real-time clock with calendar/alarm/correction functions, and three independent serial interface types: UART/LIN (2–4 channels), I²C (3–10 channels), and CSI (2–8 channels), all configurable for mixed-protocol communication in multi-sensor nodes.
