Overview
The STM32H755ZIT6 is a high-performance microcontroller from STMicroelectronics, part of the STM32H7 series. It is based on the dual-core architecture of the Arm Cortex-M7 and Cortex-M4 32-bit RISC cores. The Cortex-M7 core operates at up to 480 MHz, while the Cortex-M4 core operates at up to 240 MHz. Both cores feature a floating point unit (FPU) and support Arm single- and double-precision operations, along with a full set of DSP instructions and a memory protection unit (MPU) for enhanced application security.
This microcontroller is designed for demanding applications requiring high computational power, low power consumption, and a rich set of peripherals. It incorporates high-speed embedded memories, including 2 Mbytes of dual-bank Flash memory and up to 1 Mbyte of RAM, along with extensive I/Os and peripherals connected to various bus systems.
