Overview
R5F100JDAFA#30 from Renesas is a 52-pin LQFP-0.65mm 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for industrial control systems requiring low-power operation across -40°C to +85°C ambient.
For engineers reviewing the R5F100JDAFA#30 datasheet, R5F100JDAFA#30 pinout, R5F100JDAFA#30 application, or R5F100JDAFA#30 equivalent, key selection criteria include its 1.6–5.5 V supply range, 66 μA/MHz active current, HALT/STOP/SNOOZE low-power modes, integrated LIN-capable UART, and 52-pin LQFP package with 39 general-purpose I/Os.
Technical Context
The R5F100JDAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz), and features 1 MB address space with four register banks of eight 8-bit registers each.
It integrates dual-clock domain operation: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) for main system timing, and dedicated low-speed oscillator for RTC and watchdog timer - enabling simultaneous precision timing and ultra-low-power background operation.
