    STM32F479IIT6

    The STM32F479xx devices are based on the high-performance Arm®(a) Cortex®-M4 32-bit
    RISC core operating at a frequency of up to 180 MHz. The Cortex®-M4 core features a
    floating-point unit (FPU) single precision which supports all Arm® single-precision dataprocessing instructions and data types. It also implements a full set of DSP instructions and
    a memory protection unit (MPU) which enhances application security.
    The STM32F479xx devices incorporate high-speed embedded memories (Flash memory
    up to 2 Mbytes, up to 384 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, two 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), and a cryptographic acceleration cell. They also
    feature standard and advanced communication interfaces.
    • Up to three I2Cs
    • Six 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.
    • Four USARTs plus four UARTs
    • One USB OTG full-speed and one USB OTG high-speed with full-speed capability
    (with the ULPI)
    • Two CANs
    • One SAI serial audio interface
    • An SDMMC host interface
    • Ethernet and camera interface
    • LCD-TFT display controller
    • Chrom-ART Accelerator™
    • DSI Host.
    Advanced peripherals include an SDMMC interface, a flexible memory control (FMC)
    interface, a Quad-SPI flash memory, camera interface for CMOS sensors and a
    cryptographic acceleration cell. Refer to Table 2 for the list of peripherals available on each
    part number.
    The STM32F479xx devices operate in the –40 to +105 °C temperature range from a 1.7 to
    3.6 V power supply. A dedicated supply input for USB (OTG_FS and OTG_HS) only in full
    speed mode, is available on all packages.
    The supply voltage can drop to 1.7 V (refer to Section 2.19.2). A comprehensive set of
    power-saving modes allows the design of low-power applications.

    The STM32F479xx devices are offered in eight packages, ranging from 100 to 216 pins.
    The set of included peripherals changes with the device chosen, according to Table 2.
    These features make the STM32F479xx microcontrollers suitable for a wide range of
    applications:
    • Motor drive and application control
    • Medical equipment
    • Industrial applications: PLC, inverters, circuit breakers
    • Printers, and scanners
    • Alarm systems, video intercom, and HVAC
    • Home audio appliances
