STMicroelectronics STM32F723ICK6

Overview

STM32F723ICK6 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 (2.4 MSPS), two 12-bit DACs, and 18 timers - deployed in industrial HMI, motor control gateways, and real-time audio processing systems.

For engineers reviewing the STM32F723ICK6 datasheet, STM32F723ICK6 pinout, STM32F723ICK6 application, or STM32F723ICK6 equivalent, key selection considerations include its dual USB OTG PHY support (integrated HS/FS), 21 communication interfaces (including CAN 2.0B, SAI, SDMMC), L1 cache (8 KB I-cache + 8 KB D-cache), and TCM RAM allocation (64 KB data + 16 KB instruction) for deterministic real-time execution.

Technical Context

The STM32F723ICK6 integrates an adaptive real-time accelerator (ART Accelerator) and L1 cache enabling zero-wait-state execution from Flash or external memory. Its dual-mode Quad-SPI interface supports XIP and memory-mapped execution, while the flexible external memory controller (FMC) handles NOR/NAND, SDRAM, and PSRAM with up to 32-bit data bus width.

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 options (on-chip HS/FS or ULPI). The device includes two Serial Audio Interfaces (SAIs), audio PLLs (PLLI2S/PLLSAI), and hardware-accelerated cryptographic peripherals including CRC and true RNG.

Key Specifications

FAQ

Does STM32F723ICK6 support USB High-Speed device mode with integrated PHY?

Yes. The STM32F723ICK6 integrates a dedicated USB OTG HS controller with on-chip high-speed PHY, enabling full-speed and high-speed device/host/OTG operation without external PHY components. This is confirmed in Section 3.30 of DS11853 Rev 9 and validated by the LQFP64 pinout (PA11/PA12 for FS, PB12–PB15 for ULPI optional mode).

What is the maximum ADC sampling rate achievable in interleaved mode?

The STM32F723ICK6 achieves 7.2 MSPS aggregate sampling rate using triple interleaved mode across its three 12-bit ADCs, with synchronized triggers and shared DMA channel. Each ADC operates at 2.4 MSPS individually, and timing is coordinated via the ADC common control register (ADC_CCR), as specified in Section 3.33 and Table 6.3.24 of DS11853 Rev 9.

How is TCM RAM allocated and accessed in this device?

The device allocates 64 KB of data TCM RAM and 16 KB of instruction TCM RAM - both directly mapped into the Cortex-M7's address space and accessible at full CPU speed without cache arbitration. These regions are used for time-critical variables and interrupt service routines, respectively, and are configured via SCB->VTOR and linker script placement, per Section 3.5 and RM0410 reference manual.

Is the LQFP64 package of STM32F723ICK6 pin-compatible with any other STM32 series?

No. The LQFP64 variant of STM32F723ICK6 has a unique pinout optimized for its peripheral set (e.g., dual USB PHY signals, SAI, SDMMC) and is not pin-compatible with STM32F4/F0/F1 LQFP64 devices. Pin mapping is defined in Table 10 of DS11853 Rev 9 and verified against mechanical drawings in Section 7.1.
