STMicroelectronics' model STM32F745IEK6 is an MCU microcontroller that uses a high-performance ARM® Cortex®-M7 32-bit RISC core and operates at a frequency of up to 216MHz. The Cortex®-M7 core features single floating point unit (SFPU) precision and supports all ARM® single-precision data processing instructions and data types. It also implements a comprehensive set of DSP instructions and a Memory Protection Unit (MPU) that enhances application security.
The STM32F745IEK6 contains high-speed embedded memory with up to 1 megabyte of flash memory, 320 kilobytes of SRAM (including 64 kilobytes of data TCM RAM for critical real-time data), 16 kilobytes of instruction TCM RAM (for critical real-time examples) program), 4 kilobytes of backup SRAM, and extensive enhanced I/O connected to two APB buses, two AHB buses, a 32-bit multi-AHB bus matrix, and multi-layer AXI interconnect supporting internal and external memory access and peripherals.
STM32F745IEK6 provides three 12-bit ADCs, two DACs, a low-power RTC, thirteen general-purpose 16-bit timers (including two PWM timers for motor control and a low-power timer available in stop mode device), two general-purpose 32-bit timers, and a true random number generator (RNG).
