STMicroelectronics STM32F722ZET7

Overview

STM32F722ZET7 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 CAN 2.0B - deployed in industrial motor control systems requiring real-time deterministic response and multi-interface coordination.

For engineers reviewing the STM32F722ZET7 datasheet, STM32F722ZET7 pinout, STM32F722ZET7 application, or STM32F722ZET7 equivalent, key selection criteria include LQFP144 package compatibility, 216 MHz real-time execution with ART Accelerator and L1 cache, dual USB OTG support (HS + FS), triple-interleaved ADC throughput (7.2 MSPS), and integrated hardware crypto acceleration for secure firmware updates.

Technical Context

The STM32F722ZET7 implements a tightly coupled memory architecture with 8 KB instruction and 8 KB data L1 caches plus Adaptive Real-Time (ART) Accelerator, enabling zero-wait-state execution from Flash and external memories. Its AXI-AHB bus matrix supports concurrent high-bandwidth access across CPU, DMA, and peripherals including FMC, Quad-SPI, and dual SAI audio interfaces.

It integrates dual USB OTG controllers - one full-speed with on-chip PHY, one high-speed with dedicated DMA and dual PHY options (on-chip HS/FS or ULPI) - alongside bxCAN 2.0B, SDMMC, and flexible clock tree with multiple PLLs (main, PLLI2S, PLLSAI) for independent audio and system timing domains.

FAQ

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

The STM32F722ZET7 achieves 216 MHz via its Arm Cortex-M7 core with FPU, enabled by the Adaptive Real-Time (ART) Accelerator and 8 KB instruction/data L1 caches. This configuration allows zero-wait-state execution from embedded Flash memory, verified under industrial temperature conditions (–40°C to +105°C) with 1.7–3.6 V supply.

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

Yes - the STM32F722ZET7 integrates a full-speed USB PHY and a high-speed USB PHY on-die. The HS PHY supports 480 Mbps operation without external components when powered by a clean 1.8 V supply and properly matched per ST's layout guidelines in AN4879.

How many ADC channels and what sampling rate can be achieved in interleaved mode?

It features three independent 12-bit ADCs supporting up to 24 total channels. In triple interleaved mode, they achieve 7.2 MSPS aggregate sampling rate with hardware-synchronized triggers and <1 µs inter-converter skew - confirmed in electrical characteristics section 6.3.24 of DS11853 Rev 9.

What package and pin count does STM32F722ZET7 use?

The STM32F722ZET7 uses the LQFP144 package: 144-pin, 20 × 20 mm body, 0.5 mm lead pitch, with exposed thermal pad. Pin definitions and alternate functions are fully documented in Table 10 (pin and ball definition) and Table 12 (alternate function mapping) of DS11853 Rev 9.
