Product details
Overview
R5F51113ADNF#2A 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, and 8 KB data flash. It integrates a 12-bit A/D converter (14 channels, 1.0 µs conversion), USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and operates from 1.8–3.6 V across −40 to +85°C. It targets compact industrial control and USB-connected sensor nodes.
For engineers reviewing the R5F51113ADNF#2A datasheet, R5F51113ADNF#2A pinout, R5F51113ADNF#2A application, or R5F51113ADNF#2A equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases, and two validated alternative parts for design flexibility and supply continuity.
Technical Context
The R5F51113ADNF#2A implements the RXv1 CPU core with Harvard architecture, five-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle instruction execution. Its clock system includes high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for frequency accuracy monitoring.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 35+ event sources-including MTU2 timers and A/D conversion completion-reducing interrupt overhead in real-time control loops.

The R5F51113ADNF#2A operates at up to 32 MHz when powered from 2.7–3.6 V, 16 MHz at 2.4–2.7 V, and 8 MHz at 1.8–2.4 V. Its 32-bit RX CPU delivers 50 DMIPS at 32 MHz, with no wait states for flash access across all supported frequencies. The device is rated for −40 to +85°C operation.
Does the R5F51113ADNF#2A support USB On-The-Go (OTG) functionality?
Yes, the R5F5113ADNF#2A integrates a USB 2.0 host/function module compliant with USB OTG. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, and Battery Charging (BC) v1.2 detection. The USB0_ID pin enables OTG role negotiation, and USB0_VBUSEN/USB0_EXICEN manage VBUS control in peripheral/host configurations.
How many analog input channels does the R5F51113ADNF#2A support, and what is its A/D conversion speed?
The R5F51113ADNF#2A includes a 12-bit A/D converter with 7 input channels (AN000–AN004, AN006, AN008) in the 40-pin PWQN0040KC-A package. Minimum conversion time is 1.0 µs per channel when ADCLK runs at 32 MHz. Double-trigger mode enables synchronized sampling across multiple channels for motor control or sensor fusion.
What low-power modes are available on the R5F51113ADNF#2A, and what is the lowest supply current?
The R5F51113ADNF#2A offers three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode, supply current drops to 0.44 μA (typ.) while retaining RTC operation and SRAM contents. Wake-up occurs in 4.8 μs via external interrupt, RTC alarm, or USB resume-making it ideal for battery-powered wake-on-event systems.
