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 Flash memory up to 1 Mbyte, 320 KB of SRAM (including 64 KB of Data TCM RAM for critical real time data), 16 KB of instruction TCM RAM (for critical real time routines), 4 KB 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 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.
Advanced peripherals include an SDMMC interface, a flexible memory control (FMC) interface, a Quad SPI Flash memory interface, a camera interface for CMOS s...
