Overview

The R5F51116ADLF#UA is an entry-level 32-bit microcontroller from Renesas' RX111 group, featuring a high-performance RX CPU core running at up to 32MHz. It is specifically designed for ultra-low power applications, integrating 256KB of flash memory and 32KB of RAM into a compact 5x5mm WFLGA-64 package. The device includes a dedicated USB 2.0 Full-Speed interface capable of Host, Function, and OTG roles.

Why Choose This Part

This MCU offers a remarkable balance of 3.6mA active current at 32MHz and 1.8V to 3.6V operation, making it ideal for energy-constrained designs. Its CISC architecture achieves high code density, while the 5x5mm LGA package provides a high pin-to-size ratio for space-limited PCBs.

Applications

Battery-Powered Medical Devices
Leverages the 440nA standby current and fast wake-up times for long-term monitoring equipment.
USB Peripherals
Utilizes the integrated USB 2.0 FS controller for PC accessories and industrial interface converters.
Smart Utility Meters
Employs the on-chip RTC and hardware CRC for secure, time-stamped data logging in low-energy environments.
Portable Industrial Sensors
Uses the Event Link Controller (ELC) to manage peripheral interaction without CPU intervention, reducing power consumption.
