Product details
Overview
R5F51113ADFK#5A 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, 14-channel 12-bit A/D converter (1.0 µs conversion), dual 8-bit D/A outputs, USB 2.0 full-speed host/function/OTG, and RTC with calendar mode - deployed in industrial HMI and sensor gateway edge nodes.
For engineers reviewing the R5F5113ADFK#5A datasheet, R5F5113ADFK#5A pinout, R5F5113ADFK#5A application, or R5F5113ADFK#5A equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40°C to +85°C temperature grade, integrated E2 data flash endurance (1M erase/write cycles), low-power software standby mode (0.44 µA), and USB OTG support with BC (Battery Charger) detection.
Technical Context
The R5F5113ADFK#5A 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. It integrates a dedicated 15 kHz IWDT oscillator and clock frequency accuracy measurement circuit (CAC) for IEC 60730 compliance.
Its peripheral set includes an Event Link Controller (ELC) enabling direct module-to-module triggering without CPU intervention, a Data Transfer Controller (DTC) supporting chain transfers across four modes, and MTU2 timers with complementary PWM and phase counting - all synchronized to independently configurable ICLK, PCLK, and FCLK domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51113ADFM#3A | Same core, memory, and peripherals; differs only in package: 64-pin LFQFP (PLQP0064KB-A, 10×10 mm, 0.5 mm pitch) vs. LQFP (14×14 mm, 0.8 mm pitch) | Requires PCB layout change due to larger pad pitch and footprint; identical firmware and pin function mapping | Select for higher-density layouts where 0.5 mm pitch is preferred and thermal dissipation allows smaller body size. |
| R5F51113ADFL#3A | 48-pin LFQFP (PLQP0048KB-A); reduced I/O count (30 vs. 46), no D/A converters, only 10 A/D channels (vs. 14), no USB OTG support | Suitable for cost-sensitive, space-constrained designs omitting USB connectivity and analog output requirements | Choose when USB host/OTG and dual D/A are unnecessary, and board area or BOM cost must be minimized. |
Compared with R5F5113ADFK#5A, the R5F5113ADFM#3A offers identical functionality in a smaller 10×10 mm footprint but demands finer-pitch assembly, while R5F5113ADFL#3A sacrifices USB OTG, D/A, and 4 A/D channels to reduce pin count and cost - making it viable only where those features are excluded from the system architecture.

The R5F5113ADFK#5A 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 operations, and ultra-compact variable-length instruction encoding - enabling efficient code density and deterministic real-time execution critical for R5F5113ADFK#5A-based control applications.
Does the R5F5113ADFK#5A support USB On-The-Go (OTG) and Battery Charging (BC) detection?
Yes, the R5F5113ADFK#5A integrates a USB 2.0 host/function module that fully supports OTG and BC 1.2 detection. It includes dedicated hardware for identifying downstream charging ports (SDP, CDP, DCP) and negotiating current limits without firmware overhead - a key capability confirmed in the R5F5113ADFK#5A datasheet section "USB 2.0 host/function module (USBc)" and validated in Renesas application note R01AN2313.
What are the memory resources available on the R5F5113ADFK#5A?
The R5F5113ADFK#5A provides 64 KB of on-chip flash memory (executed at full 32 MHz with zero wait states), 10 KB of SRAM, and 8 KB of data flash rated for 1,000,000 erase/write cycles. The data flash supports Background Operation (BGO), allowing concurrent code execution and nonvolatile parameter storage - a verified feature essential for firmware updates and calibration retention in R5F5113ADFK#5A deployments.
How many analog-to-digital and digital-to-analog channels does the R5F5113ADFK#5A include?
The R5F5113ADFK#5A integrates a 12-bit A/D converter with up to 14 input channels and a minimum conversion time of 1.0 µs at 32 MHz ADCLK, plus two independent 8-bit D/A converter channels.
