Product details
Overview
R5F51114AGFM#3A from Renesas is a 32-bit RX111 Group microcontroller featuring a 32 MHz CPU core delivering 50 DMIPS, 96 KB on-chip flash memory, 16 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 with calendar mode, and operates across −40 to +105°C in a 64-pin LFQFP package.
For engineers reviewing the R5F51114AGFM#3A datasheet, R5F51114AGFM#3A pinout, R5F51114AGFM#3A application, or R5F51114AGFM#3A equivalent, this MCU supports low-power industrial sensing, USB-connected edge nodes, and real-time control systems requiring integrated analog I/O, deterministic interrupt latency, and IEC 60730-compliant safety functions.
Technical Context
The R5F51114AGFM#3A implements a CISC Harvard-architecture RX CPU with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy monitoring.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module-to-module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 82 interrupt sources - critical for deterministic sensor data acquisition and USB endpoint buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RX 32-bit CISC Harvard architecture, 32 MHz max, 50 DMIPS @ 32 MHz - enables real-time deterministic execution in motor control and USB protocol stacks. |

| SCI1/SCI5/SCI12 | Serial communication interfaces | Three SCI modules: SCI1/SCI5 support UART/I²C/SPI; SCI12 adds extended serial mode (RXDX/TXDX/SIOX) for custom protocols. |
Key Features
| Feature | Design Value |
|---|---|
| Event Link Controller (ELC) | Direct hardware linking of 35 event sources (e.g., timer overflow → ADC start) eliminates CPU polling and reduces ISR latency to sub-microsecond. |
| Data Transfer Controller (DTC) | Four transfer modes (normal/repeat/block/chain) with automatic descriptor reload - offloads DMA management from CPU during continuous USB bulk transfers. |
| IEC 60730 Compliance Support | On-chip CAC, IWDT with dedicated 15 kHz oscillator, RAM test assist - enables Class B safety certification without external watchdog or clock monitor ICs. |
| Realtime Clock (RTC) | Calendar mode with leap-year correction, alarm/interrupt/carry outputs, and software-standby wake capability - sustains timekeeping in ultra-low-power metering applications. |
| Multi-function Pin Controller (MPC) | Per-pin peripheral function selection (e.g., P40 = TXD1 or DA0 or AN008) - simplifies PCB layout reuse across variants and enables dynamic peripheral remapping at runtime. |
