1. Description

The STM32F407VGT6 series is based on the high-performance ARM Cortex-M4 32-bit RISC core, and its operating frequency is up to 168 MHz. The Cortex-M4 core has a floating point unit (FPU) single precision, which supports all ARM single precision data processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU), thereby enhancing the security of the application. The STM32F405xx and STM32F407xx series integrate high-speed embedded memory (up to 1 MB of flash memory, up to 192 KB of SRAM flash memory) , To 4 KB of spare SRAM, and a wide range of enhanced I/O and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix. All devices provide three 12-bit ADCs, two DACs, a low-power RTC, and twelve general-purpose 16-bit timers, including two PWM timers for motor control and two general-purpose 32-bit timers. A true random number generator (RNG). They also have standard and advanced communication interfaces.

5. Fully compatible with all series

STM32F405xx and STM32F407VGT6 are part of the STM32F4 series. They are fully pinto-pin, software and functional compatible with STM32F2xx devices, allowing users Try different memory densities, peripherals and performance (FPU, higher frequency) Gain greater freedom in the development cycle. STM32F405xx and STM32F407xx devices are compatible with The entire STM32F10xxx series. All function pins are pin-to-pin compatible. this However, STM32F405xx and STM32F407xx are not STM32F10xxx devices: The power schemes of the two series are different, so their The power pins are different.

6. Embedded SRAM

    1. Up to 192 KB of system SRAM, including 64 KB of CCM (core coupled memory)Data memory RAM memory is accessed (read/write) at the CPU clock speed, and the wait state is 0.

    2. 4 KB backup SRAM This area can only be accessed from the CPU. Its content is protected from potentially unwanted write accesses, and is kept in standby or VBAT mode.

7. DMA controller

The device has two general-purpose dual-port DMAs (DMA1 and DMA2) with 8 Each stream. They can manage memory to memory, peripherals to memory and Transfer from memory to peripherals. They have dedicated FIFOs for APB/AHB peripherals, Support burst transmission, designed to provide maximum peripheral bandwidth (AHB/APB). Two DMA controllers support circular buffer management, so no specific code is required Required when the controller reaches the end of the buffer. The two DMA controllers also With double buffering function, two memories can be used and switched automatically No special code buffer is required. Each stream is connected to a dedicated hardware DMA request and supports software Trigger on every stream. The configuration is between the software and the transfer size The source and destination are independent. DMA can be used for the main peripherals:

    1. SPI and I2S

    2. A generation 2C

    3. USART

    4. General, basic and advanced control timer TIMx

    5. Digital-to-analog converter

    8. ADC.

8. Digital-to-analog converter (DAC)

    Two 12-bit buffered DAC channels can be used to convert two digital signals into two Analog voltage signal output. This dual digital interface supports the following functions:

    1. Two DAC converters: one for each output channel

    2. 8-bit or 12-bit monotonic output

    3. Left or right data alignment in 12-bit mode
