STM32F407VET6

1. Description

The STM32F407VET6 is based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all Arm singleprecision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.

The STM32F407VET6 family incorporates high-speed embedded memories (Flash memory up to 1 Mbyte, up to 192 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.

All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers. a true random number generator (RNG). They also feature standard and advanced communication interfaces.

    1. Up to three I2Cs

    2. Three SPIs, two I2Ss full duplex. To achieve audio class accuracy, the I2S peripherals can be clocked via a dedicated internal audio PLL or via an external clock to allow synchronization.

    3. Four USARTs plus two UARTs

    4. An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the ULPI),

    5. Two CANs

    6. An SDIO/MMC interface

    7. Ethernet and the camera interface available on STM32F407xx devices only.

New advanced peripherals include an SDIO, an enhanced flexible static memory control (FSMC) interface (for devices offered in packages of 100 pins and more), a camera interface for CMOS sensors. The STM32F407VET6 family operates in the –40 to +105 °C temperature range from a 1.8 to 3.6 V power supply. The supply voltage can drop to 1.7 V when the device operates in the 0 to 70 °C temperature range using an external power supply supervisor: refer to Section : Internal reset OFF. A comprehensive set of power-saving mode allows the design of low-power applications.

The STM32F407VET6 family offers devices in various packages ranging from 64 pins to 176 pins. The set of included peripherals changes with the device chosen. These features make the STM32F407VET6 microcontroller family suitable for a wide range of applications:
