STMicroelectronics STM32F723ZET6

Overview

STM32F723ZET6 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), 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 STM32F723ZET6 datasheet, STM32F723ZET6 pinout, STM32F723ZET6 application, or STM32F723ZET6 equivalent, key selection criteria include LQFP144 package compatibility, 216 MHz real-time execution with ART Accelerator and L1 cache, USB HS/FS OTG dual PHY support, triple-interleaved ADC throughput (7.2 MSPS), and bxCAN 2.0B interface for deterministic fieldbus integration.

Technical Context

The STM32F723ZET6 implements an adaptive real-time accelerator (ART) with 8 KB instruction and 8 KB data caches, enabling zero-wait-state execution from Flash and external memories. Its dual-mode Quad-SPI supports XIP and memory-mapped access to external flash or PSRAM, while the AXI-AHB bus matrix ensures deterministic bandwidth allocation across CPU, DMA, and peripherals.

It integrates two independent USB controllers: OTG_FS with on-chip full-speed PHY and OTG_HS with dedicated DMA, on-chip full-speed + high-speed PHY (or ULPI option), supporting simultaneous host/device roles. The bxCAN 2.0B controller operates up to 1 Mbit/s with programmable message filtering and time-triggered communication support.

FAQ

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

The STM32F723ZET6 achieves 216 MHz maximum CPU frequency using its internal voltage regulator and adaptive real-time accelerator (ART) with 8 KB instruction and 8 KB data caches. This configuration enables zero-wait-state execution from Flash memory, verified under industrial temperature conditions (–40°C to +105°C) with 1.7–3.6 V supply. External clock sources must be within 4–26 MHz for the main PLL to lock reliably.

Does the part support USB High-Speed device mode without external PHY?

Yes - the STM32F723ZET6 integrates a dedicated USB OTG HS controller with on-chip full-speed and high-speed PHYs. When configured in HS device mode, it operates at 480 Mbit/s using internal termination and biasing, eliminating the need for external PHY components. This is confirmed in Section 3.30 of DS11853 Rev 9 and validated in ST's UM1905 reference design.

How many ADC channels can be simultaneously sampled at full rate?

Three 12-bit ADCs support simultaneous sampling in triple interleaved mode at 7.2 MSPS aggregate rate (2.4 MSPS per ADC). This requires configuring ADC1/2/3 with shared trigger (e.g., TIM8 TRGO), enabling DMA double buffering, and using the analog watchdog to monitor all 24 channels. Electrical validation confirms <1 µs inter-channel skew per DS11853 Table 6.3.24.

Is the LQFP144 package pinout compatible with other STM32F7 series MCUs?

The STM32F723ZET6 shares identical LQFP144 pinout and function mapping with STM32F722ZET6 and STM32F767ZIT6 for all power, reset, clock, and common peripheral signals (e.g., USART1, SPI1, I2C1, CAN1). However, high-speed USB, Ethernet, and certain SAI/SDMMC pins differ between F72x and F76x families - full compatibility requires verifying alternate function tables in RM0410 and DS11853 Section 4.
