STM32F745xx STM32F746xx
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® singleprecision 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 generalpurpose 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.

Full compatibility throughout the family
The STM32F745xx and STM32F746xx devices are fully pin-to-pin, compatible with the
STM32F4xxxx devices, allowing the user to try different peripherals, and reaching higher
performances (higher frequency) for a greater degree of freedom during the development
cycle.

FMC characteristics
Unless otherwise specified, the parameters given in Table 88 to Table 101 for the FMC
interface are derived from tests performed under the ambient temperature, fHCLK frequency
and VDD supply voltage conditions summarized in Table 17, with the following configuration:
•
Output speed is set to OSPEEDRy[1:0] = 11
•
Measurement points are done at CMOS levels: 0.5VDD
Refer to Section 5.3.17: I/O port characteristics for more details on the input/output
characteristics.
Asynchronous waveforms and timings
Figure 58 through Figure 61 represent asynchronous waveforms and Table 88 through
Table 95 provide the corresponding timings. The results shown in these tables are obtained
with the following FMC configuration:
•
AddressSetupTime = 0x1
•
AddressHoldTime = 0x1
•
DataSetupTime = 0x1 (except for asynchronous NWAIT mode , DataSetupTime = 0x5)
•
BusTurnAroundDuration = 0x0
•

Synchronous waveforms and timings
Figure 62 through Figure 65 represent synchronous waveforms and Table 96 through
Table 99 provide the corresponding timings. The results shown in these tables are obtained
with the following FMC configuration:
•
BurstAccessMode = FMC_BurstAccessMode_Enable;
•
MemoryType = FMC_MemoryType_CRAM;
•
WriteBurst = FMC_WriteBurst_Enable;
•
CLKDivision = 1;
•
DataLatency = 1 for NOR Flash; DataLatency = 0 for PSRAM
•
CL = 30 pF on data and address lines. CL = 10 pF on FMC_CLK unless otherwise
specified.
In all timing tables, the THCLK is the HCLK clock period.
–
For 2.7 V≤VDD≤3.6 V, maximum FMC_CLK = 108 MHz at CL=20 pF or 90 MHz at
CL=30 pF (on FMC_CLK).
