Overview

The STM32F303K8T6 is a high-performance 32-bit microcontroller based on the ARM Cortex-M4 core running at up to 72MHz. It features a Floating Point Unit (FPU) and specialized analog peripherals, including multiple 12-bit ADCs and DACs, making it suitable for precision control applications in a compact 32-pin LQFP package.

Why Choose This Part

This MCU combines a 72MHz clock speed with hardware floating-point support, enabling complex mathematical calculations without the overhead of fixed-point math. Its rich analog integration, including nine 12-bit ADC channels and three DACs, reduces the need for external signal conditioning components.

Applications

Digital Power Supplies
Leverages the high-speed 12-bit ADCs and fast PWM timers for precise voltage and current regulation.
Small Brushless DC (BLDC) Motors
Uses the Cortex-M4 DSP instructions and dedicated timers to implement efficient motor control algorithms.
Sensor Interface Nodes
Integrates 9 ADC channels and 3 DACs to interface with various analog sensors and actuators in industrial environments.
Embedded Control Systems
Ideal for space-constrained designs requiring CANbus connectivity and 5V tolerant I/Os.
