STMicroelectronics STM32F723ZEI6

Overview

STM32F723ZEI6 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), and 140 GPIOs - deployed in industrial HMI, motor control gateways, and real-time audio processing systems.

For engineers reviewing the STM32F723ZEI6 datasheet, STM32F723ZEI6 pinout, STM32F723ZEI6 application, or STM32F723ZEI6 equivalent, key selection criteria include Cortex-M7 real-time performance, integrated USB HS PHY, TCM RAM allocation for deterministic code execution, and LQFP144 package compatibility with legacy PCB footprints.

Technical Context

The STM32F723ZEI6 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 memory subsystem includes 256 KB data TCM RAM, 16 KB instruction TCM RAM, and 4 KB backup SRAM - all accessible at full 216 MHz CPU frequency.

It integrates dual USB OTG controllers: one full-speed with on-chip PHY, and one high-speed/full-speed with dedicated DMA and dual on-chip PHYs (FS + HS), supporting simultaneous host/device roles. The bxCAN 2.0B interface operates independently of USB timing domains, enabling robust automotive diagnostics and gateway arbitration.

FAQ

What is the maximum operating temperature rating for STM32F723ZEI6?

The STM32F723ZEI6 is qualified for industrial temperature range: –40°C to +105°C ambient. This rating applies to the LQFP144 package variant and is validated per JEDEC JESD22-A108. Thermal derating begins above +85°C ambient when operating at full 216 MHz with all peripherals active; design margin must account for PCB copper area and airflow.

Does STM32F723ZEI6 support external SDRAM, and what is the maximum bus width?

Yes, the STM32F723ZEI6 supports external SDRAM via its Flexible Memory Controller (FMC) with up to 16-bit data bus width and 256 MB address space. It does not support 32-bit SDRAM buses - that capability is reserved for larger packages (e.g., UFBGA176) with additional address/control lines. LQFP144 limits SDRAM to x16 configuration.

How many USB interfaces does STM32F723ZEI6 integrate, and are both PHYs on-chip?

The STM32F723ZEI6 integrates two independent USB OTG interfaces: one full-speed (OTG_FS) with fully integrated PHY, and one high-speed/full-speed (OTG_HS) with dual on-chip PHYs (FS + HS). No external PHY is required for either interface, though ULPI mode remains available for HS if external PHY is preferred.

Is the 96-bit unique ID accessible via standard firmware APIs?

Yes, the factory-programmed 96-bit unique ID is mapped to memory address 0x1FF0F420 and readable via standard HAL functions (e.g., HAL_GetUID()) or direct memory access. It is guaranteed monotonic and globally unique per die, used for secure boot key binding, device licensing, and anti-cloning measures in production firmware.
