STMicroelectronics STM32F722RET7

Overview

STM32F722RET7 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, operating 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 signal processing and deterministic I/O timing.

For engineers reviewing the STM32F722RET7 datasheet, STM32F722RET7 pinout, STM32F722RET7 application, or STM32F722RET7 equivalent, key selection criteria include its dual-mode Quad-SPI interface for external code/data expansion, ART Accelerator + L1 cache enabling zero-wait-state Flash execution, TCM RAM partitioning for time-critical routines, and integrated USB HS PHY with dedicated DMA - all validated for embedded control with mixed-signal precision and connectivity.

Technical Context

The STM32F722RET7 implements an Arm Cortex-M7 core with tightly coupled memory (TCM) architecture: 64 KB data TCM RAM for real-time data and 16 KB instruction TCM RAM for latency-sensitive firmware, both accessible at full 216 MHz CPU speed. Its ART Accelerator includes 8 KB instruction and 8 KB data caches, eliminating Flash wait states under typical execution conditions.

It integrates dual USB controllers: a full-speed OTG_FS with on-chip PHY and a high-speed OTG_HS with dedicated DMA, on-chip full-speed PHY, and optional external ULPI interface. The bxCAN controller supports ISO 11898-1:2003 compliant CAN 2.0B operation with programmable bit timing and automatic retransmission.

FAQ

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

The STM32F722RET7 achieves 216 MHz maximum CPU frequency using the internal PLL driven by either the 4–26 MHz HSE crystal or 16 MHz HSI RC oscillator. Stable operation requires proper VCAP1/VCAP2 decoupling (2.2 µF ceramic) and adherence to voltage (1.7–3.6 V) and temperature (–40°C to +85°C) specifications per DS11853 Rev 9 Section 6.3.1.

Does this MCU support external memory expansion, and what interfaces are available?

Yes - the STM32F722RET7 includes a Flexible Memory Controller (FMC) supporting SRAM, PSRAM, NOR, and NAND memories with up to 32-bit data bus width. It also features dual-mode Quad-SPI for XIP-capable serial Flash/PSRAM, enabling direct code execution from external memory without CPU intervention.

How many ADC channels are supported, and what is the maximum aggregate sampling rate?

It integrates three independent 12-bit ADCs, each supporting up to 24 input channels. In triple interleaved mode, they achieve 7.2 MSPS aggregate sampling (2.4 MSPS per ADC), with hardware synchronization and shared DMA channel - verified in DS11853 Rev 9 Section 3.33 and Table 24–27.

Is the USB High-Speed interface fully integrated, or does it require external components?

The USB OTG HS interface includes an on-chip full-speed PHY and on-chip high-speed PHY - no external transceiver is required. However, for HS operation, an external 1.8 V supply for the PHY and appropriate impedance-controlled PCB routing (90 Ω differential) are mandatory per Section 3.30 and Figure 122 of DS11853 Rev 9.
