Product details
Overview
R5F51113ADFM#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, 8 KB data flash, USB 2.0 full-speed host/function/OTG, 14-channel 12-bit ADC, dual 8-bit DAC, RTC, and ELC/DTC peripherals. It targets low-power industrial sensing and USB-connected embedded control.
For engineers reviewing the R5F51113ADFM#3A datasheet, R5F51113ADFM#3A pinout, R5F51113ADFM#3A application, or R5F51113ADFM#3A equivalent, key selection criteria include its 64-pin LFQFP (PLQP0064KB-A) package, −40°C to +85°C temperature grade, integrated USB transceiver with BC support, and dual DAC channels - all confirmed for this exact orderable part.
Technical Context
The R5F51113ADFM#3A implements the RXv1 CPU core with Harvard architecture, five-stage pipeline, and variable-length instructions, enabling 1-cycle instruction execution at 32 MHz. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy validation.
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 - both critical for deterministic real-time response in USB and motor-control applications.

FAQ
What is the maximum operating frequency and power supply range for the R5F51113ADFM#3A?
The R5F51113ADFM#3A operates at up to 32 MHz when powered from 2.7–3.6 V, delivering 50 DMIPS. At 2.4–2.7 V, max frequency is 16 MHz; at 1.8–2.4 V, it is limited to 8 MHz. Supply current is 3.2 mA (typ.) at 32 MHz, and software standby mode draws just 0.44 µA - confirmed in Renesas datasheet R01DS0190EJ0130.
Does the R5F51113ADFM#3A include an integrated USB transceiver, and what USB modes does it support?
Yes, the R5F51113ADFM#3A integrates a full-speed USB 2.0 transceiver supporting host, function, and OTG modes at 12 Mbps. It also implements Battery Charging (BC) detection and isochronous transfer - all without external PHY components. This capability is explicitly documented for the R5F51113ADFM#3A in the RX111 Group datasheet.
How many analog-to-digital and digital-to-analog channels does the R5F51113ADFM#3A provide?
The R5F51113ADFM#3A includes a 14-channel 12-bit A/D converter with 1.0 µs minimum conversion time and a dual-channel 8-bit D/A converter. Both DAC outputs (DA0, DA1) are available exclusively on 64-pin packages such as the PLQP0064KB-A used by R5F51113ADFM#3A - verified in Table 1.2 and pin function listings.
What low-power modes are supported by the R5F51113ADFM#3A, and how fast is wake-up from standby?
The R5F51113ADFM#3A supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it consumes 0.44 µA (typ.) and recovers in 4.8 µs - fast enough to respond to real-time sensor events. Wake-up can be triggered by RTC alarm, external interrupt, or USB resume - all confirmed for R5F51113ADFM#3A in Section 1.1 of the datasheet.
Is the R5F51113ADFM#3A pin-compatible with other RX111 Group MCUs in the same package?
Yes, all RX111 Group MCUs in the PLQP0064KB-A package - including R5F51113ADFM#3A, R5F51113AGFM#3A, and R5F51111ADFM#3A - share identical pin assignments and electrical characteristics. Firmware and PCB layouts are interchangeable across these variants, differing only in flash size, temperature grade, or minor peripheral enablement - per Table 1.2 and Figure 1.3.
