Overview

The STM32L4S5VIT6 is a high-performance ultra-low-power microcontroller based on the ARM Cortex-M4 core operating at 120MHz. It features a massive 2MB of Flash memory and 640KB of RAM, making it suitable for complex embedded applications that require significant memory overhead without sacrificing power efficiency. The device integrates advanced graphics features like a Chrom-ART Accelerator and hardware cryptographic acceleration for AES and HASH algorithms.

Why Choose This Part

The STM32L4S5VIT6 offers an exceptional balance of memory density and power efficiency, consuming only 18.5mA at 120MHz while providing 2MB of Flash. The inclusion of the ART Accelerator and FlexPowerControl allows for maximum performance with optimized current consumption in low-power modes. Its wide array of peripherals, including OctoSPI and USB OTG, simplifies the design of high-end consumer and industrial products.
