The STM32H743ZIT6 is a high-performance 32-bit microcontroller from STMicroelectronics based on the ARM Cortex-M7 core with double-precision Floating Point Unit (FPU) . It is part of the STM32H7 series, which represents the pinnacle of ST’s Arm Cortex-M MCU performance, delivering exceptional computational power for demanding industrial, medical, and consumer applications .
The device features a 480 MHz ARM Cortex-M7 CPU with L1 cache (16 KB I-cache + 16 KB D-cache) and ART Accelerator™, delivering up to 1027 DMIPS (2.14 DMIPS/MHz) . It integrates 2 MB Flash memory with dual-bank support for read-while-write operation, and 1 MB RAMincluding 192 KB TCM for time-critical routines .
The LQFP-144 package provides 114 I/O pins with interrupt capability . The device features a flexible external memory controller (FMC) with up to 32-bit data bus supporting SDRAM, SRAM, NOR/NAND Flash, and a dual-mode Quad-SPI interface up to 133 MHz .
Graphics capabilities include an LCD-TFT controller up to XGA resolution, Chrom-ART Accelerator™ (DMA2D) for hardware graphic acceleration, and a hardware JPEG codec .
Power management: The device features three separate power domains (D1, D2, D3) that can be independently clock-gated or switched off, operating from 1.62V to 3.6V. Low-power modes include Sleep, Stop, Standby, and VBAT, with standby current as low as 2.95 µA (RTC/LSE ON, Backup SRAM OFF) .
Key built-in peripherals:
-
True random number generator (RNG) for cryptographic operations
-
CRC calculation unit for data integrity
-
SWD and JTAG debug interfaces with 4 KB embedded trace buffer
