STMicroelectronics STM32H723VGT6

Overview

STM32H723VGT6 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 STM32H723VGT6 datasheet, STM32H723VGT6 pinout, STM32H723VGT6 application, or STM32H723VGT6 equivalent, key selection criteria include LQFP100 package compatibility, 550 MHz M7 core performance with L1 cache, dual 16-bit ADC interleaving capability, integrated Chrom-ART accelerator for XGA LCD-TFT rendering, and hardware cryptographic support including ROP/PC-ROP and 96-bit UID.

Technical Context

The STM32H723VGT6 implements a dual-bank Arm Cortex-M7 core with tightly coupled memory architecture: 32 KB instruction and 32 KB data L1 caches enable zero-wait-state execution from flash or external memory, while the MPU enforces memory isolation for safety-critical tasks. Its clock system integrates multiple PLLs (including audio PLL for SAI), HSI48/HSI/CSI/LSE oscillators, and dynamic voltage scaling across operating modes.

Peripherals are organized into domain-specific buses with dedicated DMA controllers: 4 DMA engines (1 MDMA + 2 dual-port DMAs + 1 basic DMA) offload CPU for concurrent high-bandwidth transfers - e.g., simultaneous Octo-SPI XiP fetch, DCMI frame capture, and Ethernet packet buffering - all coordinated via the advanced bus matrix and AXI/AHB/APB interconnect.

FAQ

What kind of microcontroller is STM32H723VGT6?

STM32H723VGT6 is a high-performance STM32H7 microcontroller built around a 32-bit Arm Cortex-M7 core running up to 550 MHz. STM32H723VGT6 includes double-precision FPU support, DSP instructions, MPU protection, 32 Kbytes of instruction cache, 32 Kbytes of data cache, and a performance profile suited to demanding control, graphics, and connectivity designs.

How much flash and SRAM does STM32H723VGT6 provide?

STM32H723VGT6 provides 1024 Kbytes of embedded flash memory and 564 Kbytes of SRAM with ECC coverage. The SRAM structure includes AXI SRAM, DTCM RAM, ITCM RAM, shared ITCM/AXI memory, D2-domain SRAM blocks, D3-domain SRAM, and 4 Kbytes of backup SRAM, giving STM32H723VGT6 strong memory flexibility for real-time firmware.

What package, supply range, and temperature grade apply to STM32H723VGT6?

STM32H723VGT6 uses the 100-pin LQFP ECOPACK2 package. In the ordering code, V means 100 pins, G means 1024 Kbytes flash, T means LQFP, and 6 means industrial -40 °C to +85 °C ambient temperature range. For the VGT configuration, STM32H723VGT6 operates from a 1.71 V to 3.6 V supply range.

Does STM32H723VGT6 support external SDRAM through FMC?

STM32H723VGT6 includes the Flexible Memory Controller family feature set, but the LQFP100 VGT variant should not be treated as an SDRAM design option. The 16-bit SDRAM/LPSDR SDRAM controller availability is associated with suitable 144-pin STM32H723 variants, so STM32H723VGT6 designs should plan external memory through exposed FMC signals and Octo-SPI instead of assuming SDRAM.

What external memory choices are practical with STM32H723VGT6?

STM32H723VGT6 offers one Octo-SPI interface and FMC-related external memory capability subject to package pin availability. The Octo-SPI block can operate with single, dual, quad, or octal SPI memories and supports indirect, status-polling, and memory-mapped modes. This makes STM32H723VGT6 suitable for designs using external serial NOR flash, serial PSRAM, or memory-mapped expansion.

Can STM32H723VGT6 support graphics and display acceleration?

STM32H723VGT6 includes the Chrom-ART Accelerator, also called DMA2D, and supports LCD-TFT controller functionality. DMA2D can fill image areas, copy image regions, convert pixel formats, and blend layers independently from the CPU. For STM32H723VGT6 display designs, frame-buffer size and placement should be planned around internal SRAM and practical external memory options.

What analog features are available in STM32H723VGT6?

STM32H723VGT6 includes a strong analog subsystem for mixed-signal control designs. The device family provides two 16-bit ADCs, one 12-bit ADC, two DAC channels, two operational amplifiers, two comparators, DFSDM support, and internal temperature sensing. For STM32H723VGT6, the final analog channel count depends on the LQFP100 pinout and the selected alternate-function mapping.

Which communication interfaces make STM32H723VGT6 suitable for connected equipment?

STM32H723VGT6 supports a broad communication set, including Ethernet with RMII on the VGT package option, USB 2.0 OTG high-speed/full-speed capability, two FDCAN controllers plus one TT-FDCAN interface, five I2C interfaces, multiple USART/UART channels, SPI/I2S, SAI audio interfaces, SDMMC, HDMI-CEC, SWPMI, SPDIFRX, and MDIO-related connectivity.

What clock architecture should designers consider for STM32H723VGT6?

STM32H723VGT6 combines several internal and external clock options for performance, communication, and low-power operation. Internal sources include 64 MHz HSI, 48 MHz HSI48, 4 MHz CSI, and 32 kHz LSI, while external options include 4-50 MHz HSE and 32.768 kHz LSE. STM32H723VGT6 clock-tree planning is especially important for USB, Ethernet, FDCAN, ADC, audio, and display timing.

What should be checked before using STM32H723VGT6 as an equivalent MCU?

Before using STM32H723VGT6 as an equivalent MCU, compare the LQFP100 pinout, 1024 Kbytes flash size, 564 Kbytes SRAM structure, 80 GPIO availability, exposed memory-interface signals, Ethernet mode, USB requirements, ADC channel mapping, boot configuration, clock tree, power range, and firmware assumptions.
