Description

The STM32F479xx devices are based on the high-performance ARM® 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 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 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

•

An USB OTG full-speed and a 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 mode 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.
