Description

The STM32F765xx, STM32F767xx, STM32F768Ax and STM32F769xx 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 floating point unit (FPU) which supports ARM®

double-precision and 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 STM32F765xx, STM32F767xx, STM32F768Ax and STM32F769xx devices incorporate

high-speed embedded memories with a Flash memory up to 2 Mbytes, 512 Kbytes of

SRAM (including 128 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, 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). They also feature standard and

advanced communication interfaces.

•

Up to four I2Cs

•

Six SPIs, three I2Ss in half-duplex mode. 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)

•

Three CANs

•

Two SAI serial audio interfaces

•

Two SDMMC host interfaces

•

Ethernet and camera interfaces

•

LCD-TFT display controller

•

Chrom-ART Accelerator™

•

SPDIFRX interface

•

HDMI-CEC

Advanced peripherals include two SDMMC interfaces, a flexible memory control (FMC)

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

to Table 2: STM32F765xx, STM32F767xx, STM32F768Ax and STM32F769xx features and

peripheral counts for the list of peripherals available on each part number.

The STM32F765xx, STM32F767xx, STM32F768Ax and STM32F769xx devices operate in

the –40 to +105 °C temperature range from a 1.7 to 3.6 V power supply. Dedicated supply

inputs for USB (OTG_FS and OTG_HS) and SDMMC2 (clock, command and 4-bit data) are

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 2.18.2: Internal reset OFF). A comprehensive set of power-saving mode

allows the design of low-power applications.
