Renesas R5F51113ADNF#UA

Overview

R5F51113ADNF#UA 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, 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC with calendar mode, and hardware event link controller (ELC) for low-latency peripheral coordination - deployed in industrial sensor nodes and USB-connected embedded control systems.

For engineers reviewing the R5F5113ADNF#UA datasheet, R5F51113ADNF#UA pinout, R5F51113ADNF#UA application, or R5F51113ADNF#UA equivalent, key selection criteria include its 40-pin HWQFN (PWQN0040KC-A, 6 × 6 mm, 0.5 mm pitch) package, −40 to +85°C temperature grade (D version), integrated USB transceiver with BC support, dual 16-bit timer units (MTU2 ×6, CMT ×2), and E2 data flash endurance of 1,000,000 erase/write cycles.

Technical Context

The R5F51113ADNF#UA 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. Its clock system integrates PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and CAC for real-time frequency accuracy monitoring.

Peripheral coordination is handled by the Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention - critical for deterministic motor control and low-power sensor wake-up. The Data Transfer Controller (DTC) supports chain transfer across four interrupt sources, while the USB module complies fully with USB 2.0, supporting isochronous transfers and Battery Charging (BC) v1.2.

The R5F51113ADNF#UA operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RX CPU core features a five-stage pipeline, 64-bit accumulator for single-cycle 32×32 multiply-accumulate, and ultra-compact variable-length instruction set - enabling efficient code density and deterministic real-time execution critical for R5F51113ADNF#UA-based control applications.

Does the R5F51113ADNF#UA support USB On-The-Go (OTG)?

Yes, the R5F51113ADNF#UA includes full USB 2.0 OTG support via its integrated USB host/function module. It implements USB ID pin sensing, VBUS monitoring, and OTG chip control signals (USB0_EXICEN, USB0_VBUSEN), enabling automatic role switching between host and device modes - a confirmed capability documented in Section 1.4 and Table 1.1 of the R01DS0190EJ0130 datasheet for R5F51113ADNF#UA.

What are the analog capabilities of the R5F51113ADNF#UA?

The R5F51113ADNF#UA integrates a 12-bit successive approximation register (SAR) ADC with up to 14 input channels (10 usable in its 40-pin HWQFN variant), minimum conversion time of 1.0 µs at 32 MHz ADCLK, and double-trigger mode for motor control synchronization. It also includes two 8-bit voltage-output DACs (DA0/DA1) with 0–VCC range, plus an on-die temperature sensor digitized through the same ADC - all verified in Sections 1.1 and Table 1.2 of the R5F51113ADNF#UA datasheet.

Which package and pin count does the R5F51113ADNF#UA use?

The R5F51113ADNF#UA uses the PWQN0040KC-A package: a 40-pin wettable flank QFN measuring 6 × 6 mm with 0.50 mm pitch and an exposed thermal pad. This package supports 24 general-purpose I/O pins, USB DP/DM, analog inputs, DAC outputs, and dedicated reset/clock pins - as specified in Figure 1.6 and Table 1.5 of the R5F51113ADNF#UA datasheet (R01DS0190EJ0130).

What low-power modes are available on the R5F51113ADNF#UA?

The R5F51113ADNF#UA offers three configurable low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode, it draws just 0.44 µA typical and wakes in 4.8 µs - enabled by dedicated low-speed oscillators and hardware-peripheral retention. These modes are managed via the LPMCR register and supported by multiple wake-up sources including RTC alarm, external interrupt, and USB resume - all confirmed in Section 1.1 of the R5F51113ADNF#UA datasheet.
