Overview
R5F51117ADLF#UA from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 384 KB on-chip flash, 64 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 operation from 1.8–3.6 V across −40°C to +85°C - deployed in industrial HMI, portable medical sensors, and USB-connected IoT edge nodes.
For engineers reviewing the R5F51117ADLF#UA datasheet, R5F51117ADLF#UA pinout, R5F51117ADLF#UA application, or R5F51117ADLF#UA equivalent, this page delivers verified package mapping (PWLG0064KA-A, 5×5 mm WFLGA), confirmed peripheral channel counts (6 MTU channels, 3 SCI, 1 RIIC, 1 RSPI), low-power mode timing (4.8 μs wake-up from software standby), and functional alternatives for USB-enabled embedded control designs.
Technical Context
The R5F51117ADLF#UA implements a CISC Harvard architecture 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 frequency accuracy monitoring.
Peripheral coordination is managed via Event Link Controller (ELC), enabling direct module triggering without CPU intervention, and Data Transfer Controller (DTC) supporting chain transfers across four modes. The MCU supports IEC 60730-compliant safety functions including IWDT with dedicated 15 kHz oscillator and RAM test assist circuits.

Its RX CPU core features a five-stage pipeline, variable-length instruction set, and 64-bit accumulator capable of single-cycle 32×32 multiply-accumulate operations - enabling deterministic real-time execution in USB and motor control applications where R5F51117ADLF#UA is deployed.
Does the R5F51117ADLF#UA support USB On-The-Go (OTG) and Battery Charging (BC) functionality?
Yes, the R5F51117ADLF#UA integrates a USB 2.0 full-speed host/function/OTG module compliant with BC 1.2 specification. It supports isochronous transfers and includes dedicated hardware for VBUS monitoring (USB0_VBUS), ID detection (USB0_ID), and overcurrent protection (USB0_OVRCURA/B). This makes R5F51117ADLF#UA suitable for portable devices requiring dual-role connectivity and intelligent charging negotiation.
What are the analog capabilities of the R5F51117ADLF#UA, and how are they implemented?
The R5F51117ADLF#UA includes a 12-bit successive-approximation A/D converter with 14 input channels and minimum 1.0 µs conversion time at 32 MHz ADCLK, plus two 8-bit D/A converter channels.

These features enable precision sensor interfacing in applications such as medical monitors and industrial transducers where R5F51117ADLF#UA serves as the primary signal acquisition node.
How does the R5F51117ADLF#UA manage low-power operation, and what are its key sleep modes?
The R5F5117ADLF#UA supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.44 µA and recovers in 4.8 µs - critical for battery-powered endpoints. Power domains are segmented, and peripherals like RTC and IWDT remain active during standby. This behavior is fully specified in the R5F51117ADLF#UA datasheet and validated across its −40°C to +85°C operating range.
What package type and pin count does the R5F51117ADLF#UA use, and what are its board-level implications?
