Overview
The STM32F217IET6 is a high-performance microcontroller from STMicroelectronics, part of the STM32F21x family. It is based on the ARM Cortex-M3 32-bit RISC core, operating at a frequency of up to 120 MHz. This MCU is distinguished by its high-speed embedded memories, extensive range of enhanced I/Os and peripherals, and advanced communication interfaces. The device includes an adaptive real-time memory accelerator (ART Accelerator) that enables 0-wait state program execution from Flash memory at the maximum CPU frequency. This makes it highly efficient for demanding applications.
