STMicroelectronics STM32F722VET7TR

Overview

STM32F722VET7TR 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 (including TCM and backup RAM), USB OTG HS/FS, three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, and 21 communication interfaces-including CAN 2.0B, dual SAI, and Quad-SPI-targeting real-time industrial HMI and motor control systems.

For engineers reviewing the STM32F722VET7TR datasheet, STM32F722VET7TR pinout, STM32F722VET7TR application, or STM32F722VET7TR equivalent, key selection criteria include LQFP100 package compatibility, 216 MHz Cortex-M7 execution with ART Accelerator and L1 cache, dual USB OTG support (HS + FS), triple-interleaved ADC throughput (7.2 MSPS), and integrated audio peripherals (SAI, I2S, audio PLLs) for embedded audio processing.

Technical Context

The STM32F722VET7TR implements a tightly coupled Arm Cortex-M7 core with 8 KB instruction and 8 KB data caches, enabling zero-wait-state execution from Flash via the Adaptive Real-Time (ART) Accelerator. Its memory subsystem includes 256 KB data TCM RAM for deterministic real-time data handling and 16 KB instruction TCM RAM for latency-critical routines.

It integrates dual USB OTG controllers-one full-speed with on-chip PHY, one high-speed with dedicated DMA and dual PHY options-and supports advanced connectivity via 2× SAI, 5× SPI (3 with muxed I2S), 4× USART/UART, 3× I2C, SDMMC, and bxCAN 2.0B, all synchronized through a multi-layer AXI/AHB bus matrix and 16-stream DMA with FIFO support.

Key Specifications

Pinout & Package

LQFP100 (14 × 14 mm) package with 100 pins, 138 5 V-tolerant I/Os, and 136 fast I/Os supporting up to 108 MHz toggle rate. Pin functions include dedicated VCAP1/VCAP2 for voltage regulator stabilization, NRST for reset, BOOT0/BOOT1 for boot mode selection, and multiple alternate-function mappings for peripheral routing (e.g., TIMx_CHy, USARTx_TX/RX, SAI1/2, USB_OTG_HS/FS).

FAQ

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

The STM32F722VET7TR achieves 216 MHz maximum CPU frequency using the Arm Cortex-M7 core with Adaptive Real-Time (ART) Accelerator and 8 KB instruction/data caches. This enables zero-wait-state execution from embedded Flash memory. The clock tree supports multiple PLL configurations, including main PLL driven by HSE (4–26 MHz) or HSI (16 MHz), with programmable dividers/multipliers to reach exact 216 MHz while maintaining stability across temperature and voltage.

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

Yes, the STM32F722VET7TR supports external SDRAM via its Flexible Memory Controller (FMC) with up to 32-bit data bus width. It supports LPDDR/SDR SDRAM with configurable timing parameters (tRCD, tRP, tRC, etc.) and automatic refresh control. The FMC also handles NOR, PSRAM, NAND, and SRAM, allowing unified memory mapping and XIP execution from external devices when paired with Quad-SPI.

How many USB interfaces does it have, and what are their capabilities?

The STM32F722VET7TR integrates two independent USB controllers: OTG_FS (full-speed, with on-chip PHY) and OTG_HS (high-speed, supporting both on-chip full-speed PHY and external ULPI PHY). OTG_HS requires external PHY for high-speed operation but can function as full-speed device/host using its internal FS PHY. Both support device/host/OTG roles, dedicated DMA, and battery charging detection (BCD) per USB Battery Charging Spec 1.2.

What low-power modes are available, and what peripherals remain active in Stop mode?

The STM32F722VET7TR supports Sleep, Stop, and Standby modes. In Stop mode (regulator ON), the 16 KB instruction TCM RAM, 4 KB backup SRAM, RTC, LSE oscillator, and low-power timer (LPTIM1) remain active. All clocks except those needed for these peripherals are gated. Wakeup sources include EXTI lines, RTC alarm, LPTIM1 trigger, and USB wakeup event-with typical wakeup time under 5 µs from Stop mode with regulator ON.
