Product details

Overview

STM32F407ZGT6 from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit microcontroller with FPU, operating at up to 168 MHz (210 DMIPS), featuring 1 MB 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 STM32F407ZGT6 datasheet, STM32F407ZGT6 pinout, STM32F407ZGT6 application, or STM32F407ZGT6 equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN arbitration latency, ART Accelerator-enabled zero-wait-state flash execution, and DCMI interface bandwidth for embedded vision preprocessing.

Technical Context

The device integrates an Adaptive Real-time Accelerator (ART) enabling deterministic 168 MHz execution from flash memory without wait states. Its multi-AHB bus matrix concurrently routes CPU, DMA, and peripheral traffic across flash, SRAM, CCM, and FSMC-addressed memories.

It implements two independent USB PHYs - one full-speed on-chip (OTG_FS), one high-speed with ULPI interface and dedicated DMA (OTG_HS) - alongside a fully featured 10/100 Ethernet MAC with MII/RMII support, IEEE 1588v2 timestamping, and hardware checksum offload.

IC Role / Device Role / Timing Role: Primary application processor executing protocol stacks, managing Ethernet MAC DMA descriptors, and synchronizing packet timestamps via IEEE 1588v2 hardware.

Use Value: Hardware-accelerated timestamping reduces software overhead by >90% versus software-only PTP implementations, enabling sub-100 ns sync accuracy.

Use Scenario: Compact programmable logic controller handling motion control, safety I/O, and HMI rendering on a single SoC.

IC Role / Device Role / Timing Role: Real-time executor of IEC 61131-3 logic with deterministic 100 µs scan cycles, leveraging CCM SRAM for state variables and dual CAN for distributed I/O backplane.

Use Value: Dual bxCAN interfaces allow concurrent safety (CANopen Safety) and standard automation (CANopen DS-301) traffic without arbitration delay or software multiplexing.

Embedded Vision Edge Node

USB Host-Based Data Acquisition System

Use Scenario: Low-power machine vision node capturing and preprocessing images from rolling-shutter CMOS sensors for defect detection.

IC Role / Device Role / Timing Role: DCMI receiver feeding pixel data directly into DMA-managed SRAM buffers; Cortex-M4+FPU performs Sobel edge detection and histogram analysis in real time.

Use Value: 54 MB/s DCMI bandwidth sustains QVGA@60 fps capture without frame dropping; ART Accelerator ensures consistent 168 MHz compute throughput during burst processing.

Use Scenario: Portable test equipment acquiring analog sensor data via USB-connected DAQ modules while running local FFT analysis.

Use Value: Dedicated OTG_HS DMA channel guarantees 480 Mbps bandwidth allocation to DAQ streams, preventing USB FS traffic (e.g., HID keyboard) from disrupting real-time sampling.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F407IGT6	LQFP176 package (24×24 mm); adds 32 more GPIOs and extra FSMC address lines vs. ZGT6's LQFP144.	Suitable for designs requiring expanded external memory interface or higher I/O count for modular backplanes.	Select when board layout accommodates larger footprint and additional pins are needed for parallel LCD or FPGA interfacing.
STM32H743VIT6	Cortex-M7 core @ 480 MHz; dual-core option; 2 MB flash; no DCMI; includes DSI and JPEG hardware accelerators.	Better for high-throughput GUI or AI inference; lacks native camera interface and dual CAN - requires external bridge ICs.	Choose for next-gen HMI or ML edge inference where raw compute outweighs legacy interface retention.

Compared with STM32F407ZGT6, the IG variant offers pin-compatible expansion for memory-rich systems, while the H743 trades legacy industrial interfaces (DCMI, dual CAN) for higher performance and modern multimedia engines - making ZGT6 optimal for cost-sensitive, interface-locked gateway designs.

FAQ

What is the maximum operating temperature range for STM32F407ZGT6?

The STM32F407ZGT6 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is validated per JEDEC JESD47 and confirmed in Section 6.3.1 of DS8626 Rev 12. Thermal derating begins above 70 °C ambient when using full peripheral set at 168 MHz.

Does STM32F407ZGT6 support hardware encryption acceleration?

No. The STM32F407ZGT6 does not include a cryptographic accelerator (AES, SHA, PKA). It relies on software libraries (e.g., mbed TLS) for encryption. For hardware crypto, ST recommends STM32F412xx or STM32L4+ series with CryptoCell-310 or AES engines.

Can the Ethernet MAC operate in RMII mode with 50 MHz reference clock?

Yes. The Ethernet MAC supports RMII with a precise 50 MHz reference clock applied to the ETH_RMII_REF_CLK pin. This is explicitly specified in Section 3.28 and Table 6.3.29 of DS8626 Rev 12, and requires matching PCB trace length to maintain setup/hold timing.

How many independent 12-bit ADCs does STM32F407ZGT6 integrate?

It integrates three independent 12-bit ADCs (ADC1, ADC2, ADC3), each with up to 16 external channels and 2 internal channels (temperature sensor, VREFINT). Triple interleaved mode achieves 7.2 MSPS aggregate sampling rate, as confirmed in Section 3.35 and Table 6.3.21.
