Product details

Overview

STM32F723IET7 from STMicroelectronics is a 32-bit Arm® Cortex®-M7 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 140 GPIOs - deployed in industrial HMI, motor control gateways, and real-time audio processing systems.

For engineers reviewing the STM32F723IET7 datasheet, STM32F723IET7 pinout, STM32F723IET7 application, or STM32F723IET7 equivalent, key selection criteria include its dual USB OTG PHY support (integrated HS/FS), ART Accelerator + L1 cache enabling zero-wait-state Flash execution, TCM RAM partitioning for deterministic real-time routines, and bxCAN 2.0B interface for automotive-grade communication.

Technical Context

The STM32F723IET7 implements an Arm Cortex-M7 core with tightly coupled memory (TCM) architecture: 64 KB data TCM RAM for time-critical variables and 16 KB instruction TCM RAM for latency-sensitive code, both accessible at full 216 MHz CPU frequency. Its adaptive real-time accelerator (ART) includes 8 KB instruction and 8 KB data caches to eliminate Flash wait states.

It integrates dual USB OTG controllers - one full-speed with on-chip PHY, one high-speed with dedicated DMA and dual PHY options (on-chip HS/FS or ULPI) - alongside a flexible external memory controller supporting SDRAM, NOR/NAND, and PSRAM, enabling complex embedded applications requiring external frame buffers or firmware overlays.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F767ZIT6	Higher Flash (2 MB), larger package (LQFP144), adds Ethernet MAC, no USB HS PHY - uses external PHY	Better suited for networked industrial controllers requiring TCP/IP stack and large code footprint	Select when Ethernet connectivity and >1 MB Flash are mandatory; avoid if LQFP100 footprint or integrated USB HS is required.
STM32H743VIT6	Higher CPU speed (480 MHz), dual-core (Cortex-M7 + M4), 1 MB Flash, enhanced security (AES/HASH/PUF), no USB HS PHY	Targeted at safety-critical or crypto-intensive applications needing ASIL-B compliance or secure boot chain	Choose for next-gen designs demanding higher compute density or PSA Level 3 certification - not drop-in due to pinout and peripheral register differences.

Compared with STM32F767ZIT6 and STM32H743VIT6, the STM32F723IET7 delivers optimal balance of USB HS integration, compact LQFP100 packaging, and deterministic real-time performance - making it ideal for cost-constrained, space-limited edge nodes where dual USB roles and TCM-based latency control are essential.

FAQ

What is the maximum operating temperature rating for STM32F723IET7?

The STM32F723IET7 is qualified for industrial temperature range: –40°C to +105°C ambient. This rating applies to the LQFP100 package under specified thermal conditions (JEDEC JESD51-2), with derating required above 85°C ambient depending on PCB copper area and airflow. Thermal resistance (θ_JA) is 37°C/W per datasheet Table 15.

Does STM32F723IET7 support USB High-Speed device mode with on-chip PHY?

Yes - the STM32F723IET7 integrates a dedicated USB OTG HS controller with on-chip high-speed PHY, supporting full-speed and high-speed device/host/OTG operation without external transceivers. It requires only 27 Ω series resistors on DP/DM lines and proper 90 Ω differential impedance routing per Section 3.30 of DS11853 Rev 9.

How much SRAM is allocated to TCM and what is its access latency?

The STM32F723IET7 allocates 16 KB as instruction TCM (ITCM) and 64 KB as data TCM (DTCM), both accessible at full 216 MHz with zero wait states and no cache arbitration delay. These regions are mapped to fixed AXI addresses (0x00000000 for ITCM, 0x20000000 for DTCM) and are protected by the MPU for deterministic real-time execution.

Can the STM32F723IET7 execute code directly from external SDRAM via the FMC?

No - the Flexible Memory Controller (FMC) supports external SDRAM for data storage only; code execution is restricted to internal Flash, SRAM, or TCM memory. The FMC does not provide XIP (eXecute-In-Place) capability for SDRAM due to lack of prefetch and timing constraints; however, DMA can efficiently move code segments into ITCM for execution.
