Product details
Overview
R5F51113ADFL#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 KB flash, 10 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D converter (14 channels), 8-bit D/A (2 channels), RTC, and operates from 1.8–3.6 V in industrial temperature range (−40°C to +85°C). It targets compact embedded control with integrated analog and connectivity.
For engineers reviewing the R5F51113ADFL#3A datasheet, R5F51113ADFL#3A pinout, R5F51113ADFL#3A application, or R5F51113ADFL#3A equivalent, key selection criteria include USB OTG support, 14-channel 12-bit ADC with double-trigger for motor sensing, 2-channel 8-bit DAC, software standby mode (0.44 μA), and 48-pin LFQFP (PLQP0048KB-A) package compatibility.
Technical Context
The R5F51113ADFL#3A implements the RXv1 CPU core with Harvard architecture, five-stage pipeline, and variable-length instructions enabling ultra-compact code. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy monitoring - all configurable per domain (ICLK/PCLK/FCLK).
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 35+ event sources - critical for deterministic real-time response in low-power modes like software standby (4.8 μs wake-up).

This enables dual-role operation - acting as either a USB device or host - confirmed in Section 1.1 and Table 1.1 of the official datasheet.
How many analog-to-digital converter (ADC) channels does the R5F51113ADFL#3A include, and what is its resolution?
The R5F51113ADFL#3A features a single 12-bit successive approximation register (SAR) ADC with up to 14 input channels (AN000–AN015, excluding AN005 and AN007). Minimum conversion time is 1.0 μs at 32 MHz ADCLK, and it supports double-trigger mode for synchronized sampling - detailed in Section 1.1 and Table 1.2 of R01DS0190EJ0130.
