STMicroelectronics STM32F723VEY6TR

Overview

STM32F723VEY6TR 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, dual USB OTG (FS/HS), three 12-bit ADCs (up to 7.2 MSPS in triple interleaved mode), and two 12-bit DACs. It targets real-time industrial control, motor drive, and audio processing systems requiring deterministic execution and rich peripheral integration.

For engineers reviewing the STM32F723VEY6TR datasheet, STM32F723VEY6TR pinout, STM32F723VEY6TR application, or STM32F723VEY6TR equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, USB HS/FS dual-role capability, 140 GPIOs (138 5 V-tolerant), and support for external SDRAM/NOR via Flexible Memory Controller - critical for HMI, gateway, and edge AI inference edge nodes.

Technical Context

The device integrates an adaptive real-time accelerator (ART Accelerator) and 8 KB instruction + 8 KB data L1 cache, enabling zero-wait-state execution from Flash or external memory. Its dual-mode Quad-SPI interface supports XIP and memory-mapped execution from serial flash.

It features two independent USB OTG controllers: one full-speed with on-chip PHY, and one high-speed/full-speed with dedicated DMA and dual PHY (on-chip HS + FS or ULPI). The bxCAN 2.0B controller supports time-triggered communication, while the dual SAI interfaces enable stereo I²S/TDM audio streaming with hardware FIFOs and clock synchronization.

FAQ

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

The STM32F723VEY6TR achieves 216 MHz via its internal PLL, fed by either the 4–26 MHz HSE crystal oscillator or the 16 MHz HSI RC oscillator. The ART Accelerator and 8 KB instruction/data L1 cache eliminate Flash wait states, enabling sustained 216 MHz execution with full DMIPS rating. Voltage scaling (VOS1) and proper VCAP decoupling are mandatory for stable operation at this frequency.

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

Yes, the STM32F723VEY6TR supports external SDRAM up to 256 Mbit using its Flexible Memory Controller (FMC) with 16-bit data bus and dedicated SDRAM command signals (CK, CKE, CAS, RAS, WE). The FMC implements full SDRAM initialization sequences and refresh control in hardware, eliminating CPU overhead. LQFP100 package exposes all required SDRAM pins except DQ[15:8] - limiting to 8-bit SDRAM data width unless using larger packages.

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

The STM32F723VEY6TR integrates two independent USB controllers: USB_OTG_FS (full-speed only, with on-chip PHY) and USB_OTG_HS (high-speed/full-speed, with dedicated DMA and dual PHY support). HS mode requires either the on-chip HS PHY (for self-powered designs) or external ULPI PHY (for bus-powered or noise-sensitive applications). Both support device, host, and OTG roles simultaneously.

What are the key differences between STM32F722xx and STM32F723xx variants?

The STM32F723xx adds USB OTG HS PHY support (including HS PHY regulator and external resistor network), enhanced USB HS PLL specifications, and additional USB HS-specific electrical characteristics - absent in F722xx. Functionally identical otherwise: same core, memory, peripherals, and pinout across shared packages. The 'VE' suffix denotes 512 KB Flash and LQFP100 package in both families.
