STM32L4R5VIT6
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.
