Product details
Overview
STM32F407ZET7 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 protocol bridging and deterministic network timing.
For engineers reviewing the STM32F407ZET7 datasheet, STM32F407ZET7 pinout, STM32F407ZET7 application, or STM32F407ZET7 equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, triple 12-bit ADCs (7.2 MSPS interleaved), camera interface (DCMI) bandwidth up to 54 MB/s, and dual USB OTG controllers with dedicated DMA and on-chip PHYs.
Technical Context
The STM32F407ZET7 integrates an Adaptive Real-time Accelerator (ART Accelerator) enabling zero-wait-state execution from flash at 168 MHz, alongside a multi-AHB bus matrix for concurrent peripheral access. Its memory subsystem includes 64 KB core-coupled memory (CCM) for time-critical code/data and 512 KB of embedded flash with ECC and 20-year data retention.
It implements dual USB OTG controllers - one full-speed (OTG_FS) with integrated PHY, and one high-speed/full-speed (OTG_HS) with ULPI support and dedicated DMA - plus a 10/100 Ethernet MAC with MII/RMII physical layer interface, IEEE 1588v2 hardware timestamping, and dedicated DMA channel for deterministic packet handling.

FAQ
What is the maximum operating temperature range for STM32F407ZET7?
The STM32F407ZET7 is rated for industrial temperature operation from –40 °C to +85 °C ambient, validated per DS8626 Rev 12 Section 6.3.1. Thermal derating begins above 70 °C ambient when operating at 168 MHz with all peripherals active; junction temperature must remain below 125 °C under sustained load.
Does STM32F407ZET7 support hardware encryption acceleration?
No - the STM32F407ZET7 does not include dedicated cryptographic accelerators (AES, SHA, PKA). It relies on software libraries (e.g., mbed TLS) or external secure elements. For hardware crypto, consider STM32L4+, STM32H7, or STM32WB families with CryptoCell or AES engines.
Can the Ethernet MAC operate in RMII mode with external PHY?
Yes - the STM32F407ZET7 Ethernet MAC supports both MII and RMII physical layer interfaces. In RMII mode, it requires only 7 signals (REF_CLK, CRS_DV, RXD[1:0], TXD[1:0], TX_EN) and operates at 50 MHz, reducing PCB routing complexity versus full MII's 16-signal interface.
Is the DCMI interface compatible with common CMOS image sensors?
Yes - the DCMI supports standard 8–14-bit parallel output sensors (e.g., OV2640, MT9V034) with programmable polarity for HSYNC/VSYNC/PIXCLK, automatic frame synchronization, and DMA-linked buffer chaining. Timing compliance is verified per DS8626 Section 6.3.27 for up to 54 MB/s throughput.
