Product details
Overview
STM32F722IET7 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 512 KB Flash, 256+16+4 KB SRAM (including TCM and backup RAM), USB OTG HS/FS, three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, and up to 21 communication interfaces - deployed in industrial HMI, motor control gateways, and embedded audio processing systems.
For engineers reviewing the STM32F722IET7 datasheet, STM32F722IET7 pinout, STM32F722IET7 application, or STM32F722IET7 equivalent, key selection considerations include its dual-mode Quad-SPI interface, ART Accelerator-enabled zero-wait-state Flash execution, 140 GPIOs (138 5 V-tolerant), and integrated USB HS PHY with dedicated DMA - critical for real-time deterministic control and high-bandwidth peripheral bridging.
Technical Context
The STM32F722IET7 implements an adaptive real-time accelerator (ART) with 8 KB instruction and 8 KB data L1 caches, enabling deterministic 0-wait-state execution from Flash or external memory. Its Cortex-M7 core includes MPU, DSP instructions, and a 216 MHz max frequency, supported by dual PLLs (main + audio PLLI2S/PLLSAI) for independent clock domain management across USB, audio, and system buses.
It integrates a flexible external memory controller (FMC) supporting NOR/NAND/SDRAM, dual SAIs for stereo I²S/TDM audio, and bxCAN 2.0B for industrial fieldbus connectivity. The device supports triple-interleaved ADC mode (7.2 MSPS aggregate) and low-power timers operational in Stop mode - essential for synchronized sensor acquisition and energy-constrained edge nodes.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F722IET7 achieves 216 MHz maximum CPU frequency using its internal voltage regulator and high-speed external crystal (4–26 MHz) fed into the main PLL. The ART Accelerator with 8 KB instruction cache enables zero-wait-state execution from Flash, eliminating pipeline stalls and ensuring deterministic timing at full speed.
Does this MCU support USB High-Speed device mode without external components?
Yes - the STM32F722IET7 integrates a full-speed USB PHY and a high-speed USB PHY on-die, allowing native USB 2.0 HS device/host/OTG operation without external transceivers. It also includes dedicated DMA channels to offload USB data transfers from the CPU, preserving real-time responsiveness.
How many ADC channels can be simultaneously sampled at full rate?
Three independent 12-bit ADCs support up to 24 total channels. In triple interleaved mode, they achieve 7.2 MSPS aggregate sampling (2.4 MSPS per ADC), with hardware synchronization ensuring simultaneous start and correlated timing - critical for three-phase motor current measurement.
What low-power modes retain RTC and backup SRAM functionality?
In Standby mode, the STM32F722IET7 retains RTC operation, 32×32-bit backup registers, and 4 KB of backup SRAM powered by VBAT. This enables calendar tracking, wake-on-alarm, and state preservation for up to 10 years on a CR2032 coin cell - verified per datasheet Section 3.17 and Table 32.
