Product details
Overview
R5F51113ADLF#UA from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 KB on-chip flash, 10 KB SRAM, 8 KB data flash, 14-channel 12-bit ADC, dual 8-bit DACs, USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial HMI, sensor node controllers, and USB-connected embedded gateways.
For engineers reviewing the R5F5113ADLF#UA datasheet, R5F51113ADLF#UA pinout, R5F51113ADLF#UA application, or R5F51113ADLF#UA equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases, and validated alternative options for design-in and supply continuity planning.
Technical Context
The R5F51113ADLF#UA 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 inter-module triggering without CPU intervention and a Data Transfer Controller (DTC) supporting chain transfers across four modes.
Its clock system includes high-speed (32 MHz ±1%) and low-speed (15 kHz) on-chip oscillators, PLL, sub-clock (32.768 kHz), and Clock Accuracy Measurement (CAC) circuit - all configurable per domain (ICLK/PCLK/FCLK). Power management supports software standby mode (0.44 μA) with 4.8 μs wake-up and three low-power states.
