The STM32F722RET7: ROHS3 compliant per, which satisfies the EU RoHS directive for lead-free soldering and material restrictions — no exemption expiry to track.
216 MHz Cortex-M7 — throughput for real-time control
The ARM Cortex-M7 core runs at 216 MHz, placing this MCU in the high-performance tier of the STM32F7 series. For a motor drive loop or an audio DSP pipeline, the 216 MHz clock delivers the instruction throughput to execute PID updates or FFT bins within a single PWM cycle. 512 KB of on-chip flash (512K x 8) and 256 KB SRAM (256K x 8) give enough headroom for a real-time OS, a communication stack, and a moderate-size application buffer without external memory. The flash is single-cycle at the core speed for most accesses, so tight loops don't stall.
Industrial temperature grade and peripheral set
Connectivity includes CANbus, USB, multiple SPI/I2C, QSPI, SAI (for audio), and SD/MMC — covering fieldbus gateways, sensor hubs, and human-machine interfaces. The 16-channel 12-bit ADC and dual 12-bit DAC handle analog feedback and output without an external converter.
