The STM32F446ZET6 is built around the high-performance  ARM^?Cortex^?-M4 32-bit RISC processor, which operates at up to 180 MHz. The Cortex^?-M4 core includes a single-precision floating-point unit (FPU) that supports all ARM^? single-precision data-processing instructions and data formats. It also has a full set of DSP instructions as well as a memory protection unit (MPU) to improve program security. The STM32F446ZET6 includes high-speed embedded memories (Flash memory up to 512 Kbytes, SRAM up to 128 Kbytes), backup SRAM up to 4 Kbytes, and a wide range of upgraded I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.

• Core: ARM^?32-bit Cortex^?-M4 CPU with FPU, Adaptive real-time accelerator (ART Accelerator) allowing 0-wait state execution from Flash memory, frequency up to 180 MHz, MPU, 225 DMIPS/1.25 DMIPS/MHz (Dhrystone 2.1), and DSP instructions
