Product details
Overview
R5F51403ADFL#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, USB 2.0 full-speed host/function/OTG, and integrated capacitive touch sensing (CTSU) for 12-channel detection - deployed in industrial HMI and portable medical devices requiring low-power operation and embedded USB connectivity.
For engineers reviewing the R5F51403ADFL#30 datasheet, R5F51403ADFL#30 pinout, R5F51403ADFL#30 application, or R5F51403ADFL#30 equivalent, this MCU delivers verified real-time performance with hardware-accelerated CTSU, deterministic interrupt latency, and dual 12-bit ADC/DAC channels - critical for touch-enabled control panels and battery-powered diagnostics equipment.
Technical Context
The R5F51403ADFL#30 implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. It integrates an Event Link Controller (ELC) enabling direct peripheral-to-peripheral triggering without CPU intervention, and a Data Transfer Controller (DTC) supporting chain transfers across four modes.
Its clock system includes independent PLL, USB-dedicated PLL, IWDT-dedicated 15 kHz oscillator, and Clock Accuracy Measurement (CAC) circuit for IEC 60730 compliance. Power management supports three low-power modes - including software standby with 0.44 µA consumption and 4.8 µs wake-up - synchronized to sub-clock (32.768 kHz) or dedicated low-speed oscillator.
