Product details
Overview
R5F51113ADFK#3A 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, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC, and operates across −40°C to +85°C - deployed in industrial HMI and sensor gateway edge nodes.
For engineers reviewing the R5F51113ADFK#3A datasheet, R5F51113ADFK#3A pinout, R5F51113ADFK#3A application, or R5F51113ADFK#3A equivalent, key selection criteria include USB OTG capability with BC support, 1.0 µs A/D conversion time at 32 MHz, software standby mode recovery in 4.8 µs, and 64-pin LQFP (PLQP0064GA-A) package compatibility with legacy PCB layouts.
Technical Context
The R5F51113ADFK#3A implements a CISC Harvard architecture with five-stage pipeline and variable-length instruction encoding, enabling ultra-compact code density and single-cycle instruction execution for real-time deterministic control. Its event link controller (ELC) enables direct inter-module triggering without CPU intervention, supporting low-latency peripheral coordination during sleep modes.
It features dual clock domains: ICLK (system clock, max 32 MHz) and PCLK (peripheral clock, max 32 MHz), with independent PLL, high-speed on-chip oscillator (32 MHz ±1% over −20°C to +85°C), and dedicated IWDT oscillator (15 kHz). The on-chip CAC validates clock accuracy per IEC 60730 Class B requirements.
Key Specifications
