Features and Applications

The STM32F205ZGT6 is a high-performance advanced ARM Cortex™-M3 32-bit RISC microcontroller. It has a core operating frequency of 120 MHz  with high-speed embedded memories and an extensive range of enhanced peripherals,I/Os connected to two APB buses.

It also feature an adaptive real-time memory accelerator (ART Accelerator™) which allows to achieve a performance equivalent to 0 wait state program execution from Flash memory at a CPU frequency up to 120 MHz
