Product details
Overview
R5F100MFAFB#V0 from Renesas is a 80-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed (41 DMIPS), 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, RTC, and DMA - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100MFAFB#V0 datasheet, R5F100MFAFB#V0 pinout, R5F100MFAFB#V0 application, or R5F100MFAFB#V0 equivalent, key selection criteria include its 80-pin LFQFP package, -40°C to +105°C industrial temperature grade (G), integrated data flash with 1M rewrite cycles, real-time clock with calendar/alarm, and support for SNOOZE mode low-power wake-up via peripheral events.
Technical Context
The R5F100MFAFB#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It supports multiple low-power modes - HALT, STOP, and SNOOZE - with independent clock gating per peripheral domain.
Its memory subsystem includes 128 KB on-chip code flash (1 KB block size, security lock), 8 KB data flash with background operation (BGO) and 1,000,000 write endurance, and 12 KB SRAM. The high-accuracy on-chip oscillator delivers ±1.0% stability across 1.8–5.5 V and -20 to +85°C.
