Overview

The STM32L433RCT6 is an ultra-low-power 32-bit microcontroller based on the ARM Cortex-M4 core running at 80MHz. It features 256KB of Flash memory and 64KB of RAM, designed specifically to balance high performance with minimal energy consumption in portable designs.

Why Choose This Part

This MCU includes ST's ART Accelerator and FlexPowerControl, allowing it to achieve high processing efficiency while drawing only 8.53mA at 80MHz in LDO mode. The inclusion of a USB interface and LCD controller reduces the need for external peripheral ICs in human-interface applications.

Applications

Battery-Powered IoT Nodes
Ideal for remote sensors requiring long battery life through its advanced low-power modes like Stop 2 and Shutdown.
Industrial Sensor Instrumentation
Utilizes the built-in 12-bit ADC and PGA for precise signal acquisition in factory automation environments.
Wearable Health Monitors
Compact 64-LQFP footprint combined with DSP instructions for real-time processing of biometric data.
