개요
Description
STM32H755XIH3 is a high‑performance MCU from STMicroelectronics’ STM32H7 family. It centers on a 32‑bit ARM Cortex‑M7 core running up to 480 MHz, delivering strong DSP and floating‑point performance for demanding embedded tasks. It combines substantial on‑chip memory with flexible external memory interfaces and a rich peripheral set, including USB (FS/HS), Ethernet MAC, CAN/FDCAN, SDIO/SPI/I2C/UART, plus LCD‑TFT, camera interface, and external memory controllers (SRAM/PSRAM/SDRAM). It also includes hardware crypto engines, RNG, and security features, plus ample DMA and safety options. Packaging typically offers high‑pin‑count options suitable for large Flash/RAM and external memory. Power modes balance performance and energy, and the device integrates multiple accelerators and multimedia features (graphic display, JPEG/MPEG hardware decode on some variants). Tooling support covers STM32CubeIDE/CubeMX, HAL/LL libraries, and ST‑Link debugging. Ideal for automotive, industrial, human‑machine interfaces, motor control, and multimedia applications requiring high CPU power and rich peripherals.
Equivalent
Direct one-to-one equivalents don’t exist across vendors. Closest ST alternatives are within the H7 line, such as STM32H745 or STM32H757, offering similar Cortex-M7 performance and memory footprint. For non‑ST options, consider high-end Cortex-M7 MCUs like NXP i.MX RT1060/1064 or Renesas RA/RX families, but pinout, Flash/RAM sizes, and peripherals differ. Use ST’s cross-reference tool or distributor support for exact substitutions.
Pinout
208 pins (LQFP208 package). It is a high-performance STM32H7 dual-core microcontroller with Cortex-M7 and Cortex-M4 cores, part of the STM32H755 family, offering rich peripherals and high-speed operation.
