STMicroelectronics STM32F723ICT6

Overview

STM32F723ICT6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 512 KB Flash, 256+16+4 KB SRAM (including TCM and backup), USB OTG HS/FS, three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, and up to 21 communication interfaces - deployed in industrial HMI, motor control gateways, and real-time audio processing systems.

For engineers reviewing the STM32F723ICT6 datasheet, STM32F723ICT6 pinout, STM32F723ICT6 application, or STM32F723ICT6 equivalent, key selection criteria include its dual USB OTG capability (HS + FS), 216 MHz real-time execution with L1 cache, triple-interleaved ADC throughput (7.2 MSPS), and support for external SDRAM/NOR via Flexible Memory Controller in embedded edge nodes requiring deterministic latency and multi-interface concurrency.

Technical Context

The STM32F723ICT6 implements an adaptive real-time accelerator (ART Accelerator) with 8 KB instruction and 8 KB data caches, enabling zero-wait-state execution from Flash or external memory. Its dual USB OTG subsystem includes dedicated DMA, on-chip full-speed PHY, and high-speed PHY (not ULPI), supporting simultaneous host/device roles.

It integrates a flexible external memory controller (FMC) supporting SRAM, PSRAM, SDRAM/LPSDR, and NOR/NAND, alongside dual-mode Quad-SPI and two Serial Audio Interfaces (SAIs) with internal audio PLL for sample-rate precision - all synchronized under a multi-source clock system including HSE (4–26 MHz), HSI (16 MHz ±1%), and LSE (32.768 kHz RTC).

FAQ

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

The STM32F723ICT6 achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and dual 8 KB L1 caches. This allows zero-wait-state execution from Flash or external memory. The clock tree supports multiple sources: HSE (4–26 MHz), HSI (16 MHz ±1%), and PLL configurations that multiply input frequencies while maintaining stability across industrial temperature ranges (–40°C to +105°C).

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

Yes, the STM32F723ICT6 supports external SDRAM through its Flexible Memory Controller (FMC), which provides a 32-bit data bus and dedicated control signals (CK, CKE, CAS, RAS, WE, BA0/BA1). It supports LPDDR/SDR SDRAM and is validated for Micron MT48LC4M32B2 and ISSI IS42S16400J devices - enabling frame buffers, audio sample storage, or real-time data logging beyond on-chip SRAM limits.

How many USB interfaces does the STM32F723ICT6 have, and what are their capabilities?

The STM32F723ICT6 integrates two independent USB controllers: OTG_FS (full-speed only, with on-chip PHY) and OTG_HS (high-speed/full-speed with integrated HS PHY and dedicated DMA). Unlike some variants, it does not expose ULPI - HS operation is self-contained. Both support device/host/OTG roles, enabling simultaneous mass storage, HID, and CDC classes without external transceivers.

What are the ADC performance specifications and how is triple interleaving implemented?

The STM32F723ICT6 features three independent 12-bit ADCs, each capable of 2.4 MSPS. In triple interleaved mode, they sample synchronously across shared channels, achieving 7.2 MSPS aggregate throughput with 12-bit resolution and <±1 LSB INL. This mode uses hardware synchronization via TIMx triggers and DMA burst transfers directly into TCM RAM - minimizing CPU overhead for high-fidelity motor current or sensor data capture.
