Overview
R5F51115AGFM#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 Kbytes of on-chip flash, 16 Kbytes of SRAM, 8 Kbytes of data flash, 14-channel 12-bit A/D converter, 2-channel 8-bit D/A converter, USB 2.0 full-speed host/function/OTG, RTC, and ELC for low-power event-driven operation - deployed in industrial HMI, sensor nodes, and USB-connected embedded control systems.
For engineers reviewing the R5F5115AGFM#3A datasheet, R5F51115AGFM#3A pinout, R5F51115AGFM#3A application, or R5F51115AGFM#3A equivalent, key selection criteria include its 64-pin LFQFP (PLQP0064KB-A) package, −40°C to +105°C extended temperature grade, integrated USB transceiver with BC support, dual D/A outputs, and software standby mode with 4.8 μs wake-up time.
Technical Context
The R5F51115AGFM#3A implements a CISC Harvard-architecture RX CPU core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for IEC 60730 compliance.
Peripheral integration includes Event Link Controller (ELC) enabling direct inter-module triggering without CPU intervention, Data Transfer Controller (DTC) supporting chain transfers across 82 interrupt sources, and MTU2 with six 16-bit timer channels supporting complementary PWM, phase counting, and A/D trigger generation - all synchronized to PCLK up to 32 MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51115ADFM#3A | Same core/peripherals, but rated for −40°C to +85°C (D-grade) instead of +105°C (G-grade); identical 128 KB flash/16 KB RAM | Suitable for commercial/industrial environments without extended thermal requirements | Select R5F51115ADFM#3A when ambient operating temperature remains ≤85°C and cost optimization is prioritized |
| R5F51116AGFM#3A | Higher memory: 256 KB flash / 32 KB RAM; otherwise identical peripheral set, package, and temperature rating | Required when firmware complexity or data logging depth exceeds 128 KB flash capacity | Choose R5F51116AGFM#3A if future firmware growth, OTA updates, or larger buffer requirements demand extra memory headroom |
Compared with R5F51115AGFM#3A, the D-grade variant trades extended temperature for lower cost, while the R5F51116AGFM#3A adds memory headroom without altering timing, power, or peripheral behavior - both retain identical pinout, USB functionality, and ELC/DTC architecture.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51115AGFM#3A?
The R5F51115AGFM#3A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RX CPU core features a five-stage pipeline, variable-length instruction encoding, and a 64-bit accumulator capable of single-cycle 32×32 multiplication with 64-bit result - enabling efficient signal processing and real-time control tasks within the R5F51115AGFM#3A.
Does the R5F51115AGFM#3A support USB On-The-Go (OTG) functionality?
Yes, the R5F51115AGFM#3A integrates a USB 2.0 host/function module that fully supports OTG operation, including BC (Battery Charger) detection, VBUS monitoring (USB0_VBUS), ID pin sensing (USB0_ID), and overcurrent protection (USB0_OVRCURA/B). This allows the R5F51115AGFM#3A to dynamically switch between host and device roles in embedded applications without external USB switches.
What are the analog capabilities of the R5F51115AGFM#3A, and are both D/A channels available in this package?
The R5F51115AGFM#3A includes a 14-channel 12-bit A/D converter with 1.0 μs minimum conversion time and a temperature sensor. It also integrates two 8-bit D/A converters (DA0 and DA1), both of which are fully supported in the 64-pin PLQP0064KB-A package used by the R5F51115AGFM#3A - confirmed in Table 1.2 of the datasheet for 64-pin variants.
What low-power modes does the R5F51115AGFM#3A support, and what is its wake-up time from standby?
The R5F51115AGFM#3A supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.44 μA (typical) while maintaining RTC operation and retaining SRAM content. Wake-up from this mode occurs in 4.8 μs upon IRQ, USB VBUS, or RTC alarm - making the R5F51115AGFM#3A well-suited for battery-powered applications requiring rapid responsiveness.
Is the R5F51115AGFM#3A pin-compatible with other members of the RX111 Group, such as R5F51116AGFM#3A?
Yes, the R5F51115AGFM#3A is pin-compatible with all other 64-pin RX111 Group variants in the PLQP0064KB-A package, including R5F51116AGFM#3A and R5F51118AGFM#3A. They share identical pin assignments, electrical characteristics, and peripheral mapping - allowing hardware reuse across memory-graded variants while scaling flash (128 KB → 256 KB → 512 KB) and RAM (16 KB → 32 KB → 64 KB) as needed in the R5F51115AGFM#3A design.
