The STM32F373VBH6 is a low-cost embedded microcontroller manufactured by STMicroelectronics and designed for use in embedded systems. It runs at up to 120MHz, has 16K of RAM and up to 2MB of Flash, and is available in two packages; the VBH6 and the VBR6.

In terms of applications, the STM32F373VBH6 is suitable for a wide range of embedded applications including embedded systems for appliances, automotive, audio, industrial, medical and more. These applications might typically involve connecting sensors, motors and other peripherals on to the microcontroller.

The STM32F373VBH6 is built around a core processor which includes a Cortex-M3 CPU with Floating Point Unit (FPU). It also contains embedded SRAM, device peripherals and debug system on chip (SoC). The microcontroller also has built-in hardware acceleration for audio processing and a wide range of communication protocols such as USB, CAN, and up to 12 serial communication interfaces.

The STM32F373VBH6 is used in many embedded systems due to its advanced features, low cost and power efficiency. It is also used in the Internet of Things (IoT) and in embedded robotics.

So how does the STM32F373VBH6 work? Its core processor contains a 32-bit ARM Cortex-M3 central processing unit (CPU), which serves as the heart of the microcontroller. This CPU is responsible for running code and controlling the microcontroller’s functions. The Cortex-M3 also contains a Floating Point Unit (FPU), which is important for running multi-precision operations such as those required by high-precision sensors and motor control.

In addition, the STM32F373VBH6 contains two additional computation engines running concurrently; the Digital Signal Processor (DSP) and the Vector Floating Point Unit (VFP). The DSP is designed for signal processing tasks and is used for fast, real-time analysis and processing of digital signals. The VFP is designed for fast floating-point numerical operations, essential for many digital signal processing algorithms.

The STM32F373VBH6 also contains a multiplexed Adress and Data Bus (ADBUS) which is used to support high-speed memory access as well as data transfer and instruction fetch. The ADBUS is connected to the Flash memory, SRAM, and peripherals allowing data transfers to occur at up to 120Mbits/second.

The microcontroller also contains its own real-time clock (RTC) and power management system. The real-time clock is useful for timekeeping while the power management system monitors and adjusts the microcontrollers’ power consumption according to its workload. This, in turn, helps extend battery life and reduce power consumption. The microcontroller also contains a security system which helps to protect the device from unauthorized users.

Finally, a debug system enables the user to debug code and monitor the performance of the processor and peripherals. The debug system also allows for real-time trace, which enables users to watch evolutionary progress of execution, check variables, and observe how their code behaves in the system.

In conclusion, the STM32F373VBH6 provides an impressive range of features and performance, making it suitable for a variety of embedded systems. Its low cost, power efficiency and versatile peripherals make it an ideal choice for applications where power consumption and space constraints are an issue.
