STMicroelectronics STM32F722ICT6

Overview

STM32F722ICT6 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), 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 STM32F722ICT6 datasheet, STM32F722ICT6 pinout, STM32F722ICT6 application, or STM32F722ICT6 equivalent, key selection considerations include its dual-mode Quad-SPI interface, ART Accelerator + L1 cache enabling zero-wait-state Flash execution, 140 GPIOs (138 5 V-tolerant), and integrated USB HS PHY with dedicated DMA - critical for real-time deterministic firmware, secure boot, and multi-protocol connectivity in resource-constrained edge devices.

Technical Context

The STM32F722ICT6 implements an adaptive real-time accelerator (ART) with 8 KB instruction and 8 KB data caches, enabling deterministic 0-wait-state execution from Flash memory and external memories. Its Cortex-M7 core includes MPU, DSP instructions, and a hardware floating-point unit supporting IEEE 754 single-precision arithmetic.

It integrates dual USB controllers: one full-speed OTG with on-chip PHY, and one high-speed/full-speed OTG with dedicated DMA, on-chip FS PHY, and optional HS PHY or ULPI interface. The flexible memory controller supports SRAM, PSRAM, SDRAM/LPSDR, and NOR/NAND, while the dual-mode Quad-SPI enables direct XIP and memory-mapped operation with up to 4-line parallel transfers.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F722ICT6 achieves 216 MHz using its Arm Cortex-M7 core with ART Accelerator and 8 KB instruction/data caches. This configuration eliminates wait states during Flash access, enabling deterministic execution. Stable operation requires proper decoupling of VCAP1/VCAP2 pins with 2.2 µF capacitors and a clean 1.7–3.6 V supply meeting ripple and sequencing specifications per DS11853 Section 6.3.3.

Does this MCU support USB High-Speed device mode without external components?

No. The STM32F722ICT6 integrates only a USB Full-Speed PHY. For USB High-Speed device mode, an external ULPI transceiver (e.g., USB334x) must be used. In contrast, the STM32F723xx variants integrate a full USB HS PHY with on-chip regulators - confirmed in DS11853 Section 3.30 and Table 2.

How many 5 V-tolerant I/Os does the LQFP64 package provide?

The STM32F722ICT6 in LQFP64 provides up to 51 5 V-tolerant I/Os, as specified in DS11853 Section 3.32 and Table 10. These pins tolerate 5 V even when VDD is 3.3 V, enabling direct connection to legacy 5 V peripherals such as RS-232 transceivers, optocouplers, and industrial sensors without level shifters.

Is the backup SRAM retained during Standby mode with VBAT connected?

Yes. When VBAT is supplied (typically 1.8–3.6 V), the 4 KB backup SRAM remains powered and retains data across all low-power modes including Standby and VBAT-only mode. This is verified in DS11853 Section 3.17 and electrical characteristics Table 33, which specifies 1.5 µA typical retention current at 25°C.
