Overview

The STM32L4R5VIT6 is a high-performance ultra-low-power microcontroller based on the Arm Cortex-M4 core running at 120MHz. It features 2MB of Flash memory and 640KB of RAM, providing significant resources for complex embedded applications while maintaining low power consumption through advanced power management modes. The integrated Chrom-ART and Chrom-GRC accelerators make it particularly well-suited for driving graphical user interfaces on small displays.

Why Choose This Part

This MCU offers a unique balance of 120MHz performance and efficiency, drawing only 18.5mA in boost mode and as little as 33nA in shutdown. The 2MB Flash and 640KB RAM eliminate the need for external memory in many graphics-heavy applications, while the ART Accelerator and GFXMMU optimize memory usage and throughput.

Applications

Wearable Devices
Utilizes the ultra-low-power modes and 640KB RAM to manage health tracking algorithms and display-rich user interfaces.
Smart Home Hubs
Serves as a central controller using the wide range of connectivity options including CANbus, USB OTG, and multiple UART/SPI interfaces.
Industrial Sensor Nodes
Enables Batch Acquisition Mode (BAM) to collect data from the 12-bit ADCs while the CPU is in a low-power state, extending battery life.
Portable Medical Equipment
Supports complex digital signal processing with the integrated FPU and DSP instructions for real-time sensor data analysis.
