STMicroelectronics STM32F723ZCT6

Overview

STM32F723ZCT6 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 CAN 2.0B - deployed in industrial HMI, motor control gateways, and real-time audio processing systems.

For engineers reviewing the STM32F723ZCT6 datasheet, STM32F723ZCT6 pinout, STM32F723ZCT6 application, or STM32F723ZCT6 equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, dual-mode Quad-SPI interface, hardware RTC with subsecond accuracy, and 140 I/Os including 138 5 V-tolerant pins for mixed-voltage system integration.

Technical Context

The STM32F723ZCT6 implements an adaptive real-time accelerator (ART Accelerator) with 8 KB instruction and 8 KB data caches, enabling zero-wait-state execution from Flash and external memories. Its AXI-AHB bus matrix supports concurrent access to Flash, SRAM, and peripherals while maintaining deterministic latency for real-time tasks.

It integrates dual USB OTG controllers - one full-speed with on-chip PHY, one high-speed with dedicated DMA and dual PHY support (on-chip FS + HS or ULPI) - alongside two Serial Audio Interfaces (SAIs) with internal audio PLLs for synchronous multi-channel audio streaming without external clocking.

FAQ

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

The STM32F723ZCT6 achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and L1 cache (8 KB instruction + 8 KB data). This configuration enables zero-wait-state execution from Flash memory, verified under 1.7–3.6 V supply and ambient temperatures up to 105°C per datasheet DS11853 Rev 9 Section 6.3.1.

Does this MCU support USB High-Speed (480 Mbit/s) natively?

Yes - the STM32F723ZCT6 integrates a dedicated USB OTG HS controller with on-chip full-speed PHY and either on-chip high-speed PHY or ULPI interface (selectable by part variant). The ZCT6 variant uses ULPI, requiring an external HS PHY such as the USB334x series for 480 Mbit/s operation.

How many 5 V-tolerant I/O pins does the LQFP144 package provide?

The STM32F723ZCT6 in LQFP144 supports up to 138 5 V-tolerant I/Os, confirmed in Section 2.2 and Table 10 of DS11853 Rev 9. This includes all GPIOs except those dedicated to USB D+/D− and oscillator inputs, enabling direct interfacing with 5 V peripherals without external level shifters.

What is the purpose of the 4 KB backup SRAM and how is it powered?

The 4 KB backup SRAM retains data during Standby and VBAT modes using the VBAT supply (1.65–3.6 V). It is accessible only when VDD is off or in low-power states, and supports 32×32-bit backup registers - used for storing calibration values, system state, or RTC alarm configurations across power cycles.
