For engineers reviewing the R5F51114ADFM#3A datasheet, R5F51114ADFM#3A pinout, R5F51114ADFM#3A application, or R5F51114ADFM#3A equivalent, key selection criteria include its 64-pin LFQFP (PLQP0064KB-A) package, −40°C to +85°C temperature grade, USB OTG capability with BC support, 1.0 µs ADC conversion time, and integrated event-link controller for low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F51114ADFM#3A 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 high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for IEC 60730 compliance.
Peripheral integration includes an Event Link Controller (ELC) enabling direct module-to-module triggering (e.g., MTU timer → ADC start), a Data Transfer Controller (DTC) supporting chain transfers across four modes, and USB 2.0 controller with dedicated transceiver, OTG support, and battery charger (BC) detection - all operating within a 1.8–3.6 V supply range.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51114ADFM#3A?
The R5F51114ADFM#3A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS (Dhrystone MIPS) performance. Its RX CPU core features a five-stage pipeline, variable-length instruction set, and 64-bit accumulator for efficient 32×32 multiply-accumulate operations - enabling deterministic real-time response in motor control and sensor processing applications.
Does the R5F51114ADFM#3A support USB On-The-Go (OTG) functionality?
Yes, the R5F51114ADFM#3A integrates a USB 2.0 host/function module with full OTG support, including BC (Battery Charger) detection, ID pin sensing, and VBUS monitoring. It operates at full-speed (12 Mbps) and supports isochronous transfers - allowing the R5F51114ADFM#3A to act as either a USB host (e.g., for flash drives) or a USB device (e.g., CDC serial) dynamically.
What are the analog capabilities of the R5F51114ADFM#3A?
The R5F51114ADFM#3A includes a 14-channel 12-bit A/D converter with 1.0 µs minimum conversion time at 32 MHz ADCLK, a temperature sensor, and two 8-bit D/A converters. Its analog section supports ratiometric or absolute reference configurations via dedicated AVCC0, AVSS0, VREFH0, and VREFL0 pins - making it suitable for precision sensor signal conditioning and closed-loop control.
How does the Event Link Controller (ELC) enhance low-power operation in the R5F51114ADFM#3A?
The ELC in the R5F51114ADFM#3A enables direct hardware-level triggering between peripherals - for example, an MTU2 timer overflow can initiate an ADC conversion or RSPI transfer without CPU intervention or interrupt latency. This allows the CPU to remain in software standby mode (0.44 µA) while peripherals coordinate autonomously, significantly reducing system power in always-on sensor nodes.
What is the data flash endurance and programming voltage for the R5F51114ADFM#3A?
The R5F51114ADFM#3A includes 8 KB of on-chip data flash rated for 1,000,000 erase/write cycles (typical) and programmable at 1.8 V. It supports Background Operation (BGO), allowing code execution during erase/write - essential for robust firmware updates and nonvolatile parameter storage in field-deployed R5F51114ADFM#3A systems.
