Product details
Overview
R5F100MJAFA#30 from Renesas is a 80-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 256 KB flash, 8 KB data flash, 20 KB RAM, 52-channel 10-bit ADC, and real-time clock with calendar function - deployed in industrial motor control, sensor hubs, and battery-powered HMI systems.
For engineers reviewing the R5F100MJAFA#30 datasheet, R5F100MJAFA#30 pinout, R5F100MJAFA#30 application, or R5F100MJAFA#30 equivalent, key selection criteria include ultra-low-power STOP mode (0.57 μA), 32 MHz max CPU speed, integrated LIN-capable UARTs, hardware DMA (4 channels), and support for self-programming with boot swap.
Technical Context
The R5F100MJAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed main system clock (up to 32 MHz) and independent low-speed oscillator for RTC/LVD operation during STOP mode.
