Description

The STM32F745xx and STM32F746xx devices are based on the high-performance ARM®

Cortex®-M7 32-bit RISC core operating at up to 216 MHz frequency. The Cortex®-M7 core

features a single floating point unit (SFPU) 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 the application security.

The STM32F745xx and STM32F746xx devices incorporate high-speed embedded

memories with a Flash memory up to 1 Mbyte, 320 Kbytes of SRAM (including 64 Kbytes of

Data TCM RAM for critical real-time data), 16 Kbytes of instruction TCM RAM (for critical

real-time routines), 4 Kbytes of backup SRAM available in the lowest power modes, and an

extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB

buses, a 32-bit multi-AHB bus matrix and a multi layer AXI interconnect supporting internal

and external memories access.

All the devices offer three 12-bit ADCs, two DACs, a low-power RTC, thirteen general-

purpose 16-bit timers including two PWM timers for motor control and one low-power timer

available in Stop mode, two general-purpose 32-bit timers, a true random number generator

(RNG). They also feature standard and advanced communication interfaces.

•

Up to four I2Cs

•

Six SPIs, three I2Ss in duplex mode. To achieve the 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

•

Two SAI serial audio interfaces

•

An SDMMC host interface

•

Ethernet and camera interfaces

•

LCD-TFT display controller

•

Chrom-ART Accelerator™

•

SPDIFRX interface

•

HDMI-CEC

Advanced peripherals include an SDMMC interface, a flexible memory control (FMC)

interface, a Quad-SPI Flash memory interface, a camera interface for CMOS sensors. Refer

to Table 2: STM32F745xx and STM32F746xx features and peripheral counts for the list of

peripherals available on each part number.

The STM32F745xx and STM32F746xx 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) is available on all the packages except LQFP100 for a greater power supply

choice.

The supply voltage can drop to 1.7 V with the use of an external power supply supervisor

(refer to Section 2.17.2: Internal reset OFF). A comprehensive set of power-saving mode

allows the design of low-power applications.

The STM32F745xx and STM32F746xx devices offer devices in 8 packages ranging from

100 pins to 216 pins. The set of included peripherals changes with the device chosen.
