STMicroelectronics STM32H723ZGT6

Overview

STM32H723ZGT6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller operating at up to 550 MHz, featuring 1 MB flash with ECC, 564 KB SRAM (all with ECC), dual 16-bit ADCs (3.6 MSPS), Ethernet MAC, USB 2.0 HS/FS OTG, and 3× FDCAN - deployed in industrial HMI controllers requiring real-time graphics, deterministic communication, and secure firmware execution.

For engineers reviewing the STM32H723ZGT6 datasheet, STM32H723ZGT6 pinout, STM32H723ZGT6 application, or STM32H723ZGT6 equivalent, key selection considerations include LQFP144 package compatibility, TCM RAM allocation for hard real-time tasks, FDCAN timing accuracy under bus load, and Chrom-ART accelerator integration for XGA-resolution LCD-TFT rendering without CPU overhead.

Technical Context

This MCU implements a dual-bank Arm Cortex-M7 core with DP-FPU, 32-KB instruction and 32-KB data L1 caches enabling zero-wait-state execution from flash or external memory. It integrates a flexible memory controller supporting SDRAM, NOR/NAND, and two Octo-SPI interfaces with XiP capability.

The peripheral subsystem includes three independent FDCAN controllers compliant with ISO 11898-1:2015, a hardware-accelerated Chrom-ART (DMA2D) engine for 2D graphics composition, and a dedicated MDMA controller with linked-list support for autonomous data movement across multiple memory domains.

FAQ

What is the maximum operating frequency and thermal envelope for STM32H723ZGT6 in LQFP144?

The STM32H723ZGT6 operates at up to 550 MHz with a maximum junction temperature of 105°C. In LQFP144 package, its thermal resistance θ_JA is 30.5°C/W (JEDEC standard board). Full performance requires adequate PCB copper pour and airflow; derating begins above 85°C ambient when sustained at 550 MHz with all peripherals active.

Does STM32H723ZGT6 support hardware-based secure boot and firmware authentication?

STM32H723ZGT6 supports ROM-based secure boot with hash-based firmware validation (SHA-256) and readout protection (ROP/PC-ROP), but lacks dedicated cryptographic accelerators (AES, PKA) found in the H733/H743 variants. Secure boot is implemented via boot ROM and internal flash option bytes - sufficient for basic anti-tampering but not for high-assurance environments requiring NIST-certified crypto engines.

Can the Chrom-ART Accelerator drive a 1280×800 display at 60 Hz without external memory?

Yes - the Chrom-ART Accelerator (DMA2D) can render layered GUIs at 1280×800@60 Hz using only internal SRAM. With 128 KB data TCM and 432 KB system RAM, it supports double-buffered frame buffers (≈2 MB for RGB565) via external SDRAM controlled by the FMC, but basic UI composition (icons, text, overlays) runs entirely from internal memory without bandwidth contention.

How many FDCAN interfaces are physically implemented and what is their maximum bit rate?

The STM32H723ZGT6 integrates three fully independent FDCAN controllers (FDCAN1–FDCAN3), each supporting ISO 11898-1:2015 CAN FD operation. All three support programmable bit rates up to 5 Mbps in FD mode and 1 Mbps in classical CAN mode, with hardware timestamping, message filtering, and Tx/Rx FIFOs - confirmed in DS13313 Rev 5 Section 3.42.
