STMicroelectronics STM32F722ICK6

Overview

STM32F722ICK6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, operating at up to 216 MHz (462 DMIPS), featuring 512 KB Flash, 256 KB SRAM (including 64 KB data TCM + 16 KB instruction TCM), USB OTG HS/FS, three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, and 18 timers. It targets real-time industrial control, motor drive, and audio processing systems requiring deterministic low-latency execution.

For engineers reviewing the STM32F722ICK6 datasheet, STM32F722ICK6 pinout, STM32F722ICK6 application, or STM32F722ICK6 equivalent, key selection criteria include TCM RAM allocation for time-critical routines, dual USB OTG support (HS/FS with dedicated DMA), ART Accelerator-enabled zero-wait-state Flash execution, and 136 fast I/Os rated to 108 MHz with 5 V tolerance.

Technical Context

The STM32F722ICK6 implements an adaptive real-time accelerator (ART) with 8 KB instruction and 8 KB data L1 caches, enabling deterministic 0-wait-state execution from embedded Flash or external memories. Its memory architecture includes separate TCM RAM blocks-64 KB data TCM for critical real-time variables and 16 KB instruction TCM for latency-sensitive code-managed independently of main SRAM.

It integrates dual USB OTG controllers: one full-speed (OTG_FS) with on-chip PHY, and one high-speed/full-speed (OTG_HS) with dedicated DMA, on-chip FS/HS PHY, and optional ULPI interface. The bxCAN 2.0B controller supports robust automotive and industrial networking, while the flexible memory controller (FMC) enables direct interfacing with SDRAM, NOR/NAND, and PSRAM.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance Cortex-M7 microcontroller applications.

Compared with STM32F723IEK6, the STM32F722ICK6 omits USB HS PHY regulator circuitry-reducing BOM cost and power in pure on-chip PHY designs-while retaining identical real-time performance and peripheral count. Versus STM32H743VIT6, it offers lower cost and smaller footprint for applications not requiring >216 MHz clocks or dual-core isolation.

FAQ

What is the maximum operating frequency and associated DMIPS rating?

The STM32F722ICK6 operates at up to 216 MHz with a measured 462 DMIPS (Dhrystone 2.1), achieving 2.14 DMIPS/MHz. This performance is sustained using the ART Accelerator and L1 cache to eliminate Flash wait states, and is validated across temperature and voltage ranges per DS11853 Rev 9 Section 6.3.1.

Does this MCU support external SDRAM, and what interface is used?

Yes, the STM32F722ICK6 supports external SDRAM via its Flexible Memory Controller (FMC), which provides a 32-bit data bus and dedicated SDRAM command sequencing. It supports LPDDR/SDR SDRAM up to 133 MHz clock rate, with configurable row/column addressing and auto-refresh control-detailed in Section 3.8 and Table 33 of DS11853 Rev 9.

How many USB interfaces does the STM32F722ICK6 integrate, and what are their capabilities?

The device integrates two independent USB controllers: OTG_FS (full-speed only, with on-chip PHY) and OTG_HS (high-speed/full-speed with dedicated DMA, on-chip FS/HS PHY, and optional ULPI). OTG_HS supports host/device/OTG roles at 480 Mbps; OTG_FS supports 12 Mbps operation with built-in transceiver-both compliant with USB 2.0 specification.

Is the STM32F722ICK6 pin-compatible with other members of the STM32F722xx family?

Yes, the STM32F722ICK6 in LQFP64 is fully pin-compatible with other LQFP64-packaged variants (e.g., STM32F722RCT6, STM32F722VCT6) within the STM32F722xx series. Differences are limited to Flash/RAM size and peripheral enablement-not pin function or electrical behavior-as confirmed in Section 2.1 ("Full compatibility throughout the family") of DS11853 Rev 9.
