Product details
Overview
R5F100MFGFA#V0 from Renesas is an RL78/G13 80-pin LQFP MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100MFGFA#V0 datasheet, R5F100MFGFA#V0 pinout, R5F100MFGFA#V0 application, or R5F100MFGFA#V0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade, LQFP-80 (14×14 mm, 0.65-mm pitch) package, integrated data flash with 1M rewrite cycles, and support for SNOOZE mode for low-latency wake-up from deep sleep.
Technical Context
The R5F100MFGFA#V0 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 features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog/RTC.
Its peripheral set includes 16-channel 16-bit timers, one 12-bit interval timer, calendar-based RTC with alarm/correction, and background operation (BGO) for concurrent code execution during data flash rewriting - enabling firmware updates without halting real-time tasks.
