STM32F407VET6 Features

  • The CPU is a high-performance Arm® 32-bit Cortex®-M4 with a floating-point unit (FPU).
  • Adaptive Real-Time Accelerator (ART Accelerator): Allows code to be run right away from flash memory, which greatly speeds up the system.
  • Plenty of storage options: up to 1 MByte in Flash, 192+4 KBytes in SRAM (including 64 KBytes in CCM data RAM), and 512 KBytes in OTP.
  • Memory controller that can work with different types of memory, like Compact Flash, SRAM, PSRAM, NOR, and NAND.
  • The LCD Parallel Interface makes it possible to connect to LCD screens in 8080/6800 modes in a number of different ways.
  • Integrated Timekeeping and Inventory Control: POR, PDR, PVD, and BOR are important management features, and the supply and I/O voltage range of 1.8 V to 3.6 V makes it suitable for a wide range of uses.
  • Advanced Direct Memory Access (DMA) and up to 24 channels over three 12-bit, 2.4 MHz per second (MSPS) analog-to-digital converters provide full support for analog data.
  • There are up to 17 timers, and each one has its own features and functions. This makes them perfect for use in control and timing systems.
  • Through Serial Wire Debug (SWD), JTAG interfaces, and the Cortex-M4 Embedded Trace MacrocellTM, there is support for fast debugging and system analysis.
  • Up to 140 interrupt-capable I/Os, including both fast I/Os and I/Os that can handle 5 V, give you a lot of ways to connect peripherals.
  • There are many I2C interfaces, USARTs and UARTs that support many protocols, SPIs that can handle high data rates, CAN interfaces, an SDIO interface, and more.
  • A real random number generator, a parallel camera interface, an Ethernet media access controller, and a USB 2.0 full-speed device/host/OTG controller all help improve the link.
  • Other features include low-power modes, a backup SRAM memory, a real-time clock that is accurate to the subsecond, a hardware calendar, a cyclic redundancy check (CRC) calculation unit, and a unique ID for identifying the device.

The TMP100NA is full of features that make it easy and accurate for engineers and designers to keep track of temperatures. The TMP100NA can be used for many different things because it has a strong core, a lot of memory choices, a wide range of connections, and better analog capabilities.

STM32F407VET6 Functional overview

  • Arm® Cortex®-M4 core with FPU and embedded Flash and SRAM

The Cortex-M4 with FPU is the most up-to-date integrated Arm processor. It was made to meet the needs of MCU implementation with a low number of pins, low power use, high computing power, and better interrupt response at an affordable price. The code-efficient Arm Cortex-M4 32-bit RISC processor with FPU gives Arm core performance in 8-bit and 16-bit memory sizes. DSP instructions make it possible to handle signals quickly and run complicated algorithms. Its single-precision FPU speeds up program development without overloading by using tools for metalanguage development.

  • Adaptive real-time memory accelerator (ART Accelerator)

The memory accelerator ART Accelerator works well with STM32 Arm® Cortex®-M4 processors with FPU. The FPU gets rid of the need for the CPU to work at lower frequencies while waiting for flash memory. This reduces the performance edge of the Arm Cortex-M4 over flash memory technologies. The speed at which programs run from 128-bit Flash memory is increased by accelerator features like an instruction prefetch queue and a branch cache. At this frequency, the processor can reach its highest speed of 210 DMIPS. The CoreMark benchmark shows that the ART accelerator works as well as running programs straight from flash memory at up to 168 MHz.

  • Memory protection unit

The memory protection unit (MPU) controls how the CPU uses memory so that one job doesn’t mess up the memory or resources of another. There can be up to 8 protected places and 8 subareas in this memory space. Protection spaces have between 32 bytes and 4 gigabytes of memory that can be used. The MPU helps protect important or approved code from tasks that have nothing to do with it.

RTOSs handle it. The RTOS can stop programs from accessing memory areas that the MPU doesn’t allow. In RTOS, the kernel can change the setting for the MPU area based on the process. Applications that don’t need the MPU can skip it.

  • External interrupt/event controller (EXTI)

The external interrupt/event driver is made up of 23 edge-detector lines that are used to make requests for interrupts and events. Each line can be set up to choose its own trigger event (a rising edge, a falling edge, or both) and can be covered on its own. The state of the interrupt requests is kept in a register called “pending.” The EXTI can find an external line whose pulse width is shorter than the time of the internal APB2 clock. There are 16 external interrupt lines that can be used to connect up to 140 GPIOs.


In conclusion, the STM32F405xx and STM32F407xx microcontrollers have a wide range of features that engineers and designers can use to meet the needs of different embedded systems. From their powerful cores and large memory choices to their wide range of connections and advanced analog features, these microcontrollers let embedded system development reach its full potential.
