STM32F765BG：High-performance and DSP with FPU, ARM Cortex-M7 MCU with 1 Mbyte Flash, 216 MHz CPU, Art Accelerator, L1 cache, SDRAM, DFSDM

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.
