Overview
The STM32F205ZET7 is a high-performance microcontroller from STMicroelectronics, part of the STM32F20x family. It is based on the Arm® 32-bit Cortex®-M3 CPU, operating at a frequency of up to 120 MHz. This microcontroller is distinguished by its adaptive real-time accelerator (ART Accelerator™), which enables 0-wait state execution performance from Flash memory. The device features extensive embedded memories, including up to 1 Mbyte of Flash memory, up to 128 Kbytes of system SRAM, and up to 4 Kbytes of backup SRAM. It also includes a wide range of enhanced I/Os and peripherals connected to multiple bus systems.
