The suffix ZIT6 decodes as: Z=144 pins, I=2MB Flash, T=LQFP package, 6=-40 to +85C industrial temperature. With 2MB dual-bank Flash supporting read-while-write, 1MB RAM (including 192KB Tightly Coupled Memory for deterministic real-time code), and L1 caches, it combines microcontroller real-time determinism with application processor performance. Three independent power domains (D1: core, D2: peripherals, D3: always-on) allow fine-grained power management. The rich peripheral set includes dual CAN FD, USB 2.0 HS OTG, Ethernet MAC, LCD-TFT controller, Chrom-ART accelerator, and hardware JPEG codec.","working_principle":"The STM32H743 operates through five subsystems: (1) Cortex-M7 Core: A 6-stage dual-issue pipeline with 16KB I-cache and 16KB D-cache, connected to Flash via a 128-bit wide bus that fills an entire cache line in a single access. The double-precision FPU and DSP instructions accelerate signal processing and floating-point math. (2) Memory Architecture: 2MB dual-bank Flash supports concurrent read and write\/erase operations. 1MB RAM is partitioned into 64KB ITCM (instruction TCM for zero-wait-state code execution), 128KB DTCM (data TCM), 864KB user SRAM across three domains, and 4KB backup SRAM. An AXI interconnect with multi-layer bus matrix provides concurrent master-to-slave access. (3) Three Power Domains: D1 houses the CPU, MDMA, and high-speed peripherals. D2 contains communication peripherals (CAN, USB, ETH, SDMMC) and timers. D3 manages reset, clock, and power control with always-on functionality. Each domain can be independently clock-gated or shut down. (4) Graphics Pipeline: The LCD-TFT controller drives displays up to XGA (1024x768). The DMA2D (Chrom-ART) accelerator performs 2D memory-to-memory copy with pixel format conversion, offloading the CPU by up to 80%. The JPEG hardware codec encodes\/decodes JPEG images at up to 150MPx\/s. (5) Communication Peripherals: Two CAN FD controllers (one with TT-CAN) support flexible data-rate CAN up to 5Mbps. Two USB OTG controllers (one HS with on-chip PHY, one FS) support device, host, and OTG modes. The Ethernet MAC supports IEEE 1588 precision time protocol.","pin_description":"
