The STM32L433VCT3 is a low-power ARM Cortex-M4 MCU from STMicroelectronics, running at 80MHz. It features 256KB flash and 64KB RAM in a 100-LQFP package. With an integrated LCD controller, DMA, and PWM, it is designed for high-performance, power-conscious applications in industrial and medical fields.
- 80MHz Cortex-M4 with FPU: Accelerates floating-point calculations for control algorithms and signal processing.
- Integrated LCD driver: Eliminates external display driver ICs, reducing BOM cost and board space.
- Wide temperature range (-40°C to 125°C): Ensures reliable operation in extreme environments.
- Low supply voltage (1.71V): Extends battery life in portable and energy-harvesting designs.
Industrial Process Control Panels
The integrated LCD controller and 80MHz Cortex-M4 allow real-time monitoring and display of process variables in PLCs and HMI panels, with 256KB flash for complex firmware.
Smart Meters (Gas/Water)
Low voltage operation down to 1.71V and multiple low-power modes enable long-term battery operation, while the LCD driver shows consumption data directly.
Automotive Body Electronics
With a 125°C temperature rating, this MCU handles engine-adjacent modules like HVAC controllers, using PWM for motor speed and WDT for fail-safe operation.
Portable Diagnostic Equipment
The Cortex-M4 FPU accelerates signal processing for portable ultrasound or ECG devices, and the 64KB RAM buffers high-resolution sensor data.
Building Automation Gateways
DMA and multiple communication interfaces (via 100-LQFP pins) support protocol conversion between Modbus and BACnet in smart building controllers.
Medical Infusion Pumps
Precise PWM control and brown-out detection ensure reliable motor actuation, while the extended temperature range supports sterilization environments.
