STMicroelectronics STM32F407ZET6

Overview

STM32F407ZET6 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 KB SRAM (including 64 KB CCM), dual 12-bit DACs, triple 12-bit ADCs (7.2 MSPS in interleaved mode), and integrated USB OTG HS/FS + 10/100 Ethernet MAC with IEEE 1588v2 support. It targets industrial control, motor drives, and real-time embedded vision systems requiring deterministic timing and multi-interface concurrency.

For engineers reviewing the STM32F407ZET6 datasheet, STM32F407ZET6 pinout, STM32F407ZET6 application, or STM32F407ZET6 equivalent, key selection criteria include its 144-pin LQFP package, 168 MHz real-time execution with ART Accelerator, hardware RTC with subsecond accuracy, dual CAN 2.0B interfaces, and parallel camera interface supporting up to 54 MB/s - critical for edge vision and synchronized connectivity designs.

Technical Context

The STM32F407ZET6 integrates an Arm Cortex-M4 core with single-precision FPU and DSP instructions, coupled with ST's Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from flash at 168 MHz. Its memory subsystem includes 512 KB of embedded flash, 192 KB of SRAM (64 KB CCM), 512 bytes OTP, and supports external memories via FSMC (NOR/NAND/PSRAM).

Peripherals are organized across three AHB buses and two APB domains: dual CAN controllers, USB OTG HS (with ULPI) and FS (on-chip PHY), 10/100 Ethernet MAC with dedicated DMA and IEEE 1588v2 hardware timestamping, and a full-featured DCMI supporting 8–14-bit parallel camera sensors at up to 54 MB/s.

FAQ

What is the maximum operating frequency and associated DMIPS rating?

The STM32F407ZET6 operates at up to 168 MHz with a measured performance of 210 DMIPS (Dhrystone 2.1), achieving 1.25 DMIPS/MHz. This rating is validated with ART Accelerator enabled and code executed from flash memory under standard test conditions (VDD = 3.3 V, TA = 25 °C).

Does the device support hardware-accelerated cryptography?

No, the STM32F407ZET6 does not include dedicated cryptographic accelerators (e.g., AES, SHA, PKA). It relies on software libraries for encryption; however, its True Random Number Generator (RNG) and CRC calculation unit provide foundational security primitives for key derivation and data integrity checks.

What are the supported low-power modes and typical current draw in Stop mode?

The device supports Sleep, Stop, and Standby modes. In Stop mode with RTC and SRAM retention enabled, typical current consumption is 36 µA (VDD = 3.3 V, TA = 25 °C), per DS8626 Rev 12 Table 23. Voltage regulator remains active, allowing fast wake-up (<5 µs) via EXTI or RTC alarm.

Can the Ethernet MAC operate in RMII mode, and what pins are required?

Yes, the Ethernet MAC supports both MII and RMII. For RMII, required pins are PA1 (REF_CLK), PA2 (CRS_DV), PA7 (RXD0), PC1 (RXD1), PC4 (TX_EN), PC5 (TXD0), PG11 (TXD1), and PG13 (MDIO)/PG14 (MDC). RMII reduces pin count by 11 versus MII while maintaining 10/100 Mbps operation.
