Product details
Overview
R5F51116ADFM#3A from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 Kbytes of on-chip flash, 32 Kbytes of SRAM, 8 Kbytes of data flash, USB 2.0 full-speed host/function/OTG, 14-channel 12-bit A/D converter, dual 8-bit D/A outputs, RTC, and operation from 1.8–3.6 V in industrial temperature range (−40 to +85°C). It targets embedded control in portable medical devices, industrial sensors, and USB-connected IoT edge nodes.
For engineers reviewing the R5F51116ADFM#3A datasheet, R5F51116ADFM#3A pinout, R5F51116ADFM#3A application, or R5F51116ADFM#3A equivalent, key selection criteria include USB OTG support with BC charging, low-power software standby mode (0.44 μA), 4.8 μs wake-up time, integrated RTC with leap-year correction, and 64-pin LFQFP package compatibility with hardware debug via FINE interface.
Technical Context
The R5F51116ADFM#3A implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and dedicated IWDT oscillator (15 kHz), all managed by the Clock Frequency Accuracy Measurement Circuit (CAC).
Peripheral coordination is handled by the Event Link Controller (ELC), which enables direct module-to-module triggering without CPU intervention-critical for deterministic timing in motor control and sensor sampling-and the Data Transfer Controller (DTC) supports chain transfers triggered by 82 interrupt sources across four transfer modes.
