The STM32F756xx devices are based on the high-performance ARM
®Cortex®-M7 32-bit RISC core operating at up to 200 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 application security.
The STM32F756xx 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, 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), and a cryptographic acceleration cell. They also feature standard and advanced communication interfaces.
