Product Introduction

Overview

The STM32F373CBT6 is a microcontroller from the STM32F373xx family, produced by STMicroelectronics. This device is based on the high-performance ARM® Cortex®-M4 32-bit RISC core, operating at a frequency of up to 72 MHz. It includes a floating-point unit (FPU), a memory protection unit (MPU), and an Embedded Trace Macrocell™ (ETM). The microcontroller features high-speed embedded memories, including up to 256 Kbytes of Flash memory and 32 Kbytes of SRAM, along with an extensive range of enhanced I/Os and peripherals connected to two APB buses.

The STM32F373CBT6 is designed for low-power applications, offering various power-saving modes such as Sleep, Stop, and Standby. It operates within a temperature range of -40 to +85 °C and is powered by a 2.0 to 3.6 V supply. The device is available in a 48-pin LQFP package.
