Overview
R5F51116AGFM#3A 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, 14-channel 12-bit ADC, dual 8-bit DACs, USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and hardware event linking for low-latency peripheral coordination - deployed in industrial sensor nodes requiring deterministic real-time control and USB connectivity.
For engineers reviewing the R5F51116AGFM#3A datasheet, R5F51116AGFM#3A pinout, R5F51116AGFM#3A application, or R5F51116AGFM#3A equivalent, this page delivers verified specifications, package-confirmed pin functions, validated alternative options, and application-specific design value - all aligned to the RX111 Group's documented 64-pin LFQFP implementation.
Technical Context
The R5F51116AGFM#3A 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 module-to-module triggering without CPU intervention, supporting concurrent peripheral operation during software standby mode.
Its clock system includes independent PLL, high-speed on-chip oscillator (32 MHz ±1% over −40°C to +105°C), sub-clock (32.768 kHz), and Clock Accuracy Measurement (CAC) circuit for IEC 60730 compliance. Power management supports three low-power modes, with 4.8 μs wake-up from software standby and 0.44 μA quiescent current.
