550 MHz Cortex-M7 — what it means for the signal chain
The STM32H723VET6 runs a single ARM Cortex-M7 core at 550 MHz, which puts it in the high-performance tier of the STM32H7 family. For a design that needs real-time FFT, motor-control loops, or Ethernet packet processing without an external FPGA, that clock rate buys you deterministic throughput — the core can execute dual-issue instructions and has a hardware FPU and DSP extensions. The 512 KB Flash and 564K x 8 RAM are sized for a firmware image that includes a TCP/IP stack and a modest data buffer; if your application needs more than that for frame storage or logging, you will be looking at the external memory interface (EBI/EMI) this part also carries.
EOL notice — plan the BOM transition now
This part is flagged end-of-life (hot). Secure last-time-buy quantities and validate a drop-in replacement before the window closes. We source this part to order against an RFQ through independent distribution.
Peripheral set and connectivity
The part includes a rich set of peripherals: dual CANbus, Ethernet MAC, USB OTG, multiple SPI/I²C/UART interfaces, plus an SPDIF and SAI audio interface. The 80 I/O lines in the 100-LQFP package give enough headroom for a sensor array or a control panel with a small TFT display. The data converters are a mix of 12-bit and 16-bit ADCs (12x12b, 18x16b) and two 12-bit DACs — adequate for industrial analog feedback loops but not precision instrumentation; expect INL in the typical MCU ADC range.
Temperature grade and operating environment
Rated for -40°C to 85°C ambient. Supply range of 1.71 V to 3.6 V.
