Overview
The STM32F746VGH6 is a high-performance microcontroller from STMicroelectronics, part of the STM32F7 series. It is based on the ARM® Cortex®-M7 32-bit RISC core, operating at a frequency of up to 216 MHz. The Cortex®-M7 core includes a single floating-point unit (SFPU) that supports all ARM® single-precision data-processing instructions and data types, as well as a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.
This microcontroller features extensive embedded memories, including up to 1 MB of Flash memory, 320 KB of SRAM (with 64 KB of data TCM RAM and 16 KB of instruction TCM RAM), and 4 KB of backup SRAM available in the lowest power modes. It also includes a wide range of enhanced I/Os and peripherals connected to multiple bus systems.
