Description
STMicroelectronics STM32H745ZIT3 Dual-Core 32-bit Microcontroller, 2 MB Flash, LQFP-144 — BOLTON SKU 67004.
About the STM32H745ZIT3 MCU, 2 MB Flash, LQFP-144
The STMicroelectronics STM32H745ZIT3 Dual-Core 32-bit microcontroller belongs to the STM32H745 line, which pairs an Arm Cortex-M7 core running at up to 480 MHz with an Arm Cortex-M4 core at up to 240 MHz in a single device. This dual-core arrangement lets designers split fast signal-processing or graphics work from real-time control or communications tasks. The device integrates 2 MB of dual-bank flash memory and up to about 1 MB of RAM, including tightly coupled memory for deterministic execution. The Cortex-M7 core includes a double-precision floating-point unit with DSP instructions, and both cores carry a memory protection unit. This ordering variant is supplied in a 144-pin LQFP package measuring 20 x 20 mm, a format that supports conventional inspection and rework.

Typical applications
A platform-class controller for demanding embedded systems — motor and power control, industrial gateways, instrumentation and human-machine interfaces — where one core handles compute-heavy processing while the other maintains hard real-time behaviour. The LQFP package suits designs that avoid BGA assembly.
