Product details
Overview
STM32F407ZET6TR from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit microcontroller with FPU, operating up to 168 MHz (210 DMIPS), featuring 512 KB flash, 192+4 KB SRAM (including 64 KB CCM), dual CAN 2.0B interfaces, 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and USB OTG HS/FS controllers - deployed in industrial gateways requiring real-time connectivity, protocol bridging, and deterministic I/O control.
For engineers reviewing the STM32F407ZET6TR datasheet, STM32F407ZET6TR pinout, STM32F407ZET6TR application, or STM32F407ZET6TR equivalent, key selection considerations include Ethernet MAC timing compliance, dual-CAN arbitration latency, ART Accelerator-enabled flash execution performance, and LQFP144 thermal dissipation under sustained 168 MHz operation.
Technical Context
The device integrates an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from flash at 168 MHz, paired with a memory protection unit (MPU) for secure task isolation. Its multi-AHB bus matrix concurrently services CPU, DMA, and peripheral accesses without contention.
It implements dual USB PHYs - one full-speed on-chip PHY for OTG_FS and one high-speed PHY with ULPI interface plus dedicated DMA for OTG_HS - alongside a fully featured 10/100 Ethernet MAC supporting MII/RMII and hardware timestamping per IEEE 1588v2 for time-sensitive networking.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | LQFP100 package (100 pins), 1 MB flash, same core/peripherals but reduced I/O count (82 vs. 114) and no RMII Ethernet pins | Suitable for space-constrained designs where full Ethernet MII/RMII and dual CAN are not required | Select when board layout area is limited and Ethernet interface can be implemented via external PHY with simplified pin routing |
| STM32H743ZIT6 | Arm Cortex-M7 core (480 MHz), 2 MB flash, 1 MB RAM, dual-core capability, enhanced crypto accelerators, no native USB HS PHY (requires external ULPI) | Targeted at higher-throughput edge AI inference and secure boot applications beyond F407's real-time determinism envelope | Choose when >210 DMIPS, hardware AES/SHA, or dual-core RTOS partitioning is mandatory - accepts increased power and complexity |
Compared with STM32F407VGT6, the ZET6 offers full Ethernet pinout and expanded I/O for complex industrial backplanes; versus STM32H743ZIT6, it delivers superior real-time predictability and integrated USB HS PHY at lower power, making it optimal for deterministic protocol gateway designs.

FAQ
What is the maximum ambient temperature rating for continuous operation in LQFP144 package?
The STM32F407ZET6TR in LQFP144 is rated for continuous operation up to +85 °C ambient (industrial grade), with junction temperature limited to +105 °C. Thermal resistance θJA is 25.5 °C/W; derating is required above 70 °C ambient if power dissipation exceeds 320 mW without PCB copper pour or airflow.
Does this part support hardware encryption acceleration?
No, the STM32F407ZET6TR does not include dedicated cryptographic accelerators (AES, SHA, PKA). It relies on software libraries (e.g., STM32Cube Crypto) or external secure elements. For hardware crypto, consider STM32L4+, STM32H7, or STM32WB series parts with CRYP/Hash peripherals.
Can the Ethernet MAC operate in RMII mode with internal 50 MHz clock generation?
Yes - the internal PLL (PLL_MII) can generate the required 50 MHz RMII reference clock from the HSE or HSI oscillator. This eliminates need for external 50 MHz crystal, reducing BOM cost and board space while maintaining IEEE 1588v2 timestamp accuracy via hardware sync.
Is the 64 KB CCM RAM accessible by DMA controllers?
No - the 64 KB CCM (core-coupled memory) is accessible exclusively by the Cortex-M4 CPU. DMA requests to CCM addresses are blocked by the AHB bus matrix, ensuring deterministic ISR latency and preventing corruption of time-critical variables stored there.
