216 MHz Cortex-M7 core — compute headroom for signal-chain and control loops
The STM32F723IET7 runs the ARM Cortex-M7 core at 216 MHz, delivering the throughput needed for real-time sensor fusion, motor-control FOC loops, and audio processing without a separate DSP. The 512 KB flash and 256 KB SRAM leave room for a full RTOS, TCP/IP stack, and application buffers — the 256 KB RAM is split across the main SRAM and tightly-coupled memory (TCM) for deterministic access.
Connectivity and mixed-signal — CAN, USB, QSPI, 24-ch ADC
The peripheral set covers CANbus, USB OTG, multiple SPI/I²C/UART, and a Quad-SPI interface for external flash — making this MCU a natural fit for industrial gateways that bridge fieldbus to Ethernet. The 24-channel 12-bit ADC samples at up to 2 MSPS, with dual 12-bit DACs for analog output; the internal oscillator saves an external crystal for non-critical timing.
