概要

Description

STM32H745ZIT3 is a high‑end MCU from ST’s STM32H7 family. It uses a dual‑core Arm Cortex‑M7 (main) and Cortex‑M4 as a companion core, with the M7 up to 480 MHz and the M4 up to 240 MHz. Memory amounts vary by package; check the datasheet for the exact Flash/RAM in the ZIT3 variant. Peripherals are rich: USB OTG FS/HS, Ethernet MAC, CAN FD, SDMMC, LCD‑TFT controller, DSI, camera interface, multiple SPI/I2S/UARTs, 12‑bit ADCs (and DAC), op‑amps, timers, cryptographic accelerators, plus MPU, caches (I/D), and a DSP/FPU on the M7. It supports external memory interfaces, large DMA, and security features. Development is supported by STM32Cube HAL/LL, CubeMX, and common IDEs. The ZIT3 suffix denotes a specific package/industrial-temperature option. Typical use cases include high‑end motor control, audio processing, display‑rich devices, and industrial automation. For exact specs (Flash/RAM, peripherals, packaging), consult the official datasheet and reference manual.
