What this STM32H723VGT6 brings to a design
The 100-LQFP package keeps the footprint manageable for a 14x14 mm body, with 80 I/O lines available.
550 MHz Cortex-M7 — what that core speed buys you
At 550 MHz, this part sits at the upper end of the STM32H7 performance tier. The ARM Cortex-M7 core includes a double-precision FPU and a cache architecture that keeps the pipeline fed from the 1 MB Flash without wait-state penalties for most tight loops. If your application runs real-time FFTs, motor-control vector math, or Ethernet packet processing, this clock rate gives you headroom to avoid a multi-core or external DSP.
Memory sizing: 1 MB Flash and 564K x 8 RAM
The 564K x 8 RAM (roughly 564 KB) handles moderate-sized data arrays, network buffers, or a display frame buffer. For projects that need more, the EBI/EMI and QSPI interfaces let you add external SRAM, PSRAM, or serial Flash without a glue-logic chip.
Connectivity: Ethernet, USB OTG, CANbus, and more
The STM32H723VGT6 includes a built-in Ethernet MAC, dual USB OTG (host/device), CANbus, and a QSPI interface. That Ethernet port supports industrial protocols like EtherCAT or Modbus TCP without an external PHY — just add a transceiver. The USB OTG allows direct connection to a PC for firmware updates or data logging.
Temperature grade and operating voltage
The internal oscillator and brown-out reset peripherals reduce external BOM count.
