The Cortex-M4 core features 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 (M PU) which enhances application security. The Cortex-M4 core with FPU will be referred to as Cortex-M4F through out this document.The STM32F405xx and STM32F407xx 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 bu ses and a 32-bit mu lti-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).STM32F407xx系列主要特性:They also feature standard and advanced communication interfaces.Up to three I2CsThree SPIs, two I2Ss full duplex. To achieve audio class accuracy, the I2S peripherals can be clocked via a dedicated internal audi o PLL or via an external clock to allow synchronization.Four USARTs plus two UARTs An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the ULPI),Two CANsAn SDIO/MMC interfaceEthernet 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 pa ckages of 100 pins and more), a camera interface for CMOS sensors. Refer to Table 2: STM32F405xx and STM32F407xx: features and peripheral counts for the list of peripherals available on each part number.The STM32F405xx and STM32F407xx 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 temperat ure 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 STM32F405xx and STM32F407xx 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 STM32F405xx and STM32F407xx microcontroller family suitable for a wide range of applications:STM32F407xx系列主要应用:Motor drive and application controlMedical equipmentIndustrial applications: PLC,inverters, circuit breakersPrinters, and scannersAlarm systems, video intercom, and HVACHome audio appliances图1.STM32F407xx系列框图STM3240G-EVAL评估板The STM3240G-EVAL evaluation board is a complete demonstration and development platform for the STM32F4 series and includes an embedded STM32F407IGH6 high-performance ARM Cortex-M4F 32-bit microcontroller.The full range of hardware features on the board is provided to help you evaluate all peripherals (USB-OTG HS, USB-OTG FS, Ethernet, motor control, CAN, MicroSD Card, smartcard, USART, Audio DAC, RS-232, IrDA, SRAM, MEMS, EEPROM. etc.) and develop your own applications.
