3,733 in stock

Overview

The R5F51115ADFL#1A is a 32-bit microcontroller from the Renesas RX111 group, featuring 128KB of Flash and 16KB of RAM. Operating at 32MHz with a CISC Harvard architecture, it is designed for ultra-low power consumption, drawing as little as 0.44 microamps in software standby mode.

Why Choose This Part

This MCU offers a balance of 32-bit performance and 8-bit power efficiency, featuring a five-stage pipeline and high-speed wake-up. It includes 5V-tolerant I/O and an Event Link Controller (ELC) that allows peripherals to interact without CPU intervention, reducing overall system power consumption.

Applications

Battery-Powered Sensors
Ideal for remote monitoring systems where extremely low standby current is required to extend battery life.
Portable Healthcare Devices
The integrated 8KB data EEPROM and low-voltage operation (1.8V to 3.6V) suit compact medical instruments.
Smart Utility Meters
Utilizes the built-in RTC, CRC, and Event Link Controller for efficient background processing in metering infrastructure.

Getting Started

Developers can begin with the Renesas e2 studio IDE and the CC-RX compiler. Hardware evaluation is typically performed using the Target Board for RX111 (RTK5RX1110C00000BR) or an E2 Lite emulator for on-chip debugging via the integrated debugging circuit.
