216 MHz Cortex-M7 with 256 KB Flash — what it means for the design
The STM32F722ICT6 is a 32-bit ARM Cortex-M7 single-core MCU from STMicroelectronics, clocked at 216 MHz with 256 KB Flash and 256 KB RAM. That core speed puts it in the performance tier for real-time motor control, audio processing, and communications bridging where the DSP extension and single-cycle multiply-accumulate matter more than a raw MHz number — the Cortex-M7 pipeline and cache architecture sustain throughput on loop-heavy code better than an M4 at the same clock. The 140 I/O in a 176-LQFP gives you room for parallel display buses, external memory interfaces, and multiple sensor banks without a CPLD.
Connectivity and analog — what the peripheral set covers
On the connectivity side, the part includes CANbus, USB, I²C, SPI, UART/USART, QSPI, SAI, and an external bus interface (EBI/EMI) — enough to talk to industrial fieldbuses, external SRAM/Flash, codec audio, and a display controller without glue logic. The 24-channel 12-bit ADC and dual 12-bit DAC handle sensor acquisition and analog output loops directly; no external ADC needed for typical control feedback.
Temperature grade and environment
Rated for -40°C to 85°C. Supply range is 1.7 V to 3.6 V.
