STMicroelectronics STM32F722VCT6

Overview

STM32F722VCT6 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+16+4 KB SRAM, USB OTG HS/FS, three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, and 18 timers - deployed in industrial motor control systems requiring deterministic real-time response and multi-interface connectivity.

For engineers reviewing the STM32F722VCT6 datasheet, STM32F722VCT6 pinout, STM32F722VCT6 application, or STM32F722VCT6 equivalent, key selection criteria include its dual USB OTG capability (HS + FS), ART Accelerator-enabled zero-wait-state Flash execution, TCM RAM partitioning for time-critical routines, and 140 I/Os with 108 MHz toggle rate and 5 V tolerance - all critical for embedded HMI, PLC edge nodes, and audio-adjacent control applications.

Technical Context

The STM32F722VCT6 implements an Arm Cortex-M7 core with L1 cache (8 KB instruction + 8 KB data), adaptive real-time accelerator (ART), and memory protection unit (MPU), enabling deterministic interrupt latency and secure code isolation. Its AXI-AHB bus matrix supports concurrent access to Flash, SRAM, and peripherals without contention.

It integrates dual USB OTG controllers - one full-speed with on-chip PHY, one high-speed with dedicated DMA and dual PHY support (full-speed + high-speed) - alongside dual SAI interfaces, Quad-SPI, and flexible external memory controller (FMC) for NOR/NAND/SDRAM expansion, making it suitable for applications demanding simultaneous high-bandwidth peripheral streaming and local storage.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the STM32F722VCT6?

The STM32F722VCT6 operates at up to 216 MHz with an integer Dhrystone 2.1 score of 462 DMIPS (2.14 DMIPS/MHz). This performance is sustained with ART Accelerator and L1 cache enabled, delivering zero-wait-state execution from Flash memory and deterministic interrupt response for hard real-time tasks.

Does the STM32F722VCT6 include an integrated USB High-Speed PHY?

No - the STM32F722VCT6 includes an integrated USB Full-Speed PHY for OTG_FS, but its USB OTG_HS interface requires an external ULPI PHY. The part supports ULPI signaling on PB14/PB15 and uses dedicated DMA for high-bandwidth transfers, confirmed in Section 3.30 of DS11853 Rev 9.

How much SRAM is allocated to TCM (Tightly Coupled Memory), and what is its purpose?

The STM32F722VCT6 provides 64 KB of data TCM RAM and 16 KB of instruction TCM RAM. These regions are physically separate from main SRAM and accessible at CPU clock speed without cache or bus arbitration delay - used for time-critical ISR code, control loop variables, and real-time buffers to guarantee worst-case execution time.

Which package variant does the 'VCT6' suffix indicate, and what are its key mechanical features?

The 'VCT6' suffix denotes the LQFP64 package: 64-pin, 10 × 10 mm body, 0.5 mm lead pitch, with exposed thermal pad. It supports reflow soldering per JEDEC J-STD-020, has a maximum height of 1.6 mm, and is rated for industrial temperature range (–40°C to +85°C), verified in Section 7.1 of DS11853 Rev 9.
