explain
STM32F765xx, STM32F767xx, STM32F768Ax, and STM32F769xx devices are based on high-performance ARM ® Cortex ®- The M7 32-bit RISC core operates at a frequency of up to 216 MHz. Cortex ®- The M7 core has a floating-point unit (FPU) that supports ARM ® Double precision and single precision data processing instructions and data types. It also implements a complete set of DSP instructions and a memory protection unit (MPU), thereby improving the security of the application.
All devices provide 3 12 bit ADCs, 2 DaCs, one low-power RTC, 12 universal 16 bit timers, including two PWM timers for motor control, two universal 32-bit timers, and a true random number generator (RNG). They also have standard and advanced communication interfaces.
Six SPIs, three I2S, in half duplex mode. In order to achieve audio accuracy, I2S
Peripheral devices can be timed through dedicated internal audio PLL or 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 (ULPI)
• Three CAN
Two SAI serial audio interfaces
Two SDMMC host interfaces
Ethernet and camera interfaces
LCD-TFT display controller
• Chrome ART Accelerator ™
SPDIFRX interface
• HDMI-CEC
The STM32F765xx, STM32F767xx, STM32F768Ax, and STM32F769xx devices operate in the temperature range of -40 to+105 ° C, with a power supply range of 1.7 to 3.6 V. Except for LQFP100, all software packages offer dedicated power inputs for USB (S OTG-FS and OTG_HS) and SDMMC2 (clock, command, and 4-bit data) to provide greater power options.
When using an external power supply main, the power supply voltage can be reduced to 1.7V (refer to section 2.18.2: Internal reset OFF). A comprehensive energy-saving mode that allows the design of low-power applications.
These features make the STM32F765xx, STM32F767xx, STM32F768Ax, and STM32F769xx microcontrollers suitable for a wide range of applications:
Motor drive and application control
Medical equipment
Industrial applications: PLC, inverter, circuit breaker
• Printers and scanners
