Overview

The STM32F405RGT6 is a high-performance ARM Cortex-M4 microcontroller operating at speeds up to 168MHz with an integrated Floating Point Unit (FPU). It features 1024KB of Flash memory and 196KB of SRAM, providing significant computational power and memory for complex embedded applications. The device includes an ART Accelerator for zero-wait-state execution from Flash and a wide range of high-speed connectivity interfaces.

Why Choose This Part

This MCU offers an excellent balance of high-speed processing and peripheral density in a compact 64-pin LQFP package. The inclusion of the ART Accelerator and 1MB of Flash allows for large, complex firmware images to run at maximum clock speed without performance bottlenecks.

Applications

Industrial Automation
Utilize the dual CAN 2.0B interfaces and multiple UARTs for robust industrial networking and sensor integration.
Motor Control
Leverage the high-speed timers and DSP instructions for precise control of brushless DC or stepper motors.
Digital Signal Processing
Perform real-time audio filtering or sensor fusion using the FPU and dedicated DSP instruction set.
USB Peripherals
Implement custom HID or mass storage devices using the integrated USB OTG Full Speed controller.
