STM32F373RBT6

Overview

The STM32F373RBT6 is a high-performance 32-bit microcontroller featuring an ARM Cortex-M4 core with a Floating Point Unit (FPU) running at 72MHz. It is uniquely distinguished by its integration of three 16-bit Sigma-Delta ADCs, making it an ideal single-chip solution for high-precision analog sensing and measurement applications.

Why Choose This Part

This MCU eliminates the need for external high-resolution ADCs, reducing BOM cost and PCB footprint for precision instruments. The combination of a 72MHz Cortex-M4 with FPU and extensive analog peripherals allows for real-time digital signal processing directly on the measured high-resolution data.

Applications

Getting Started

Develop using the STM32CubeIDE ecosystem and the STM32CubeF3 software package which includes HAL and LL drivers. For hardware evaluation, the STM32F373C-EVAL or custom boards using the LQFP-64 footprint are recommended. A standard ST-LINK/V2 or V3 debugger is required for programming and real-time debugging via SWD.
