ST STM32F745IEK6

STM32F745IEK6 Allgemeine Beschreibung

The STM32F745IEK6 is a high-performance microcontroller device that is powered by the ARM Cortex-M7 32-bit RISC core, operating at a frequency of up to 216 MHz. This core features a single floating point unit (SFPU) precision, supporting 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) for enhanced application security. With high-speed embedded memories, including a Flash memory up to 1 Mbyte and 320 Kbytes of SRAM, this device offers a robust platform for a wide range of applications
