Product details

Overview

STM32F207ZGT6J from STMicroelectronics is a high-performance Arm® Cortex®-M3 microcontroller featuring 120 MHz CPU operation, 1 MB Flash/132 KB SRAM (128+4 KB), dual CAN 2.0B interfaces, 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and USB 2.0 HS/FS OTG controllers - deployed in industrial gateways requiring real-time protocol bridging and deterministic network timing.

For engineers reviewing the STM32F207ZGT6J datasheet, STM32F207ZGT6J pinout, STM32F207ZGT6J application, or STM32F207ZGT6J equivalent, key selection criteria include Ethernet MAC + IEEE 1588v2 hardware timestamping capability, dual-CAN redundancy for fieldbus interoperability, and parallel camera interface (DCMI) support up to 48 MB/s for embedded vision edge nodes.

Technical Context

The STM32F207ZGT6J integrates a Cortex-M3 core with Adaptive Real-time Accelerator (ART™) enabling zero-wait-state execution from Flash at 120 MHz, and features a multi-AHB bus matrix for concurrent access to Flash, SRAM, and peripherals including Ethernet DMA and USB HS DMA.

Its advanced connectivity stack includes dedicated hardware for IEEE 1588v2 timestamping in the Ethernet MAC, dual CAN controllers with independent message RAMs, and a full-speed USB OTG PHY plus ULPI-capable high-speed OTG controller - enabling simultaneous USB device/host and Ethernet-based time-synchronized control in single-chip industrial controllers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F407VGT6	Higher CPU frequency (168 MHz), FPU, but no IEEE 1588v2 hardware timestamping or dual CAN; uses same LQFP100 package.	Lacks Ethernet time-synchronization capability required for TSN-compliant devices; better suited for floating-point math-intensive tasks like motor FOC.	Select when computational throughput > deterministic timing; avoid if IEEE 1588 or dual-CAN redundancy is mandatory.
STM32H743ZIT6	Cortex-M7 core (480 MHz), dual-core option, enhanced Ethernet with AVB/TSN support, but higher power and cost; LQFP144 footprint compatible.	Supports Audio Video Bridging and full TSN standards - overqualified for basic IEEE 1588v2 use cases; requires more complex power sequencing.	Choose only when migrating to next-gen TSN infrastructure; not cost-effective for legacy industrial Ethernet upgrades.

Compared with STM32F207ZGT6J, the STM32F407VGT6 trades IEEE 1588v2 and dual CAN for FPU and higher clock speed, while the STM32H743ZIT6 adds full TSN but increases design complexity and BOM cost - making the F207 optimal for cost-sensitive, time-deterministic industrial gateways.

FAQ

What is the maximum operating temperature range for STM32F207ZGT6J?

The STM32F207ZGT6J is rated for industrial temperature range: –40 °C to +85 °C ambient, verified per ST's DS6329 Rev 18 specification. It supports full functionality including Ethernet MAC, dual CAN, and DCMI at maximum junction temperature (T_j ≤ 105 °C) with appropriate PCB thermal design.

Does STM32F207ZGT6J support hardware encryption acceleration?

No - the STM32F207ZGT6J does not include dedicated cryptographic accelerators (AES, SHA, PKA). It relies on software libraries for encryption; however, its integrated TRNG and CRC unit support secure key derivation and integrity checking for lightweight protocols like DLMS/COSEM.

Can the Ethernet MAC operate in RMII mode with external PHY?

Yes - the STM32F207ZGT6J supports both MII and RMII physical layer interfaces. RMII mode uses 9 pins (REF_CLK, CRS_DV, RXD[1:0], TX_EN, TXD[1:0], TX_ER) and requires a 50 MHz reference clock; validated with common PHYs including LAN8720A and DP83848.

Is the 4 KB backup SRAM retained during VBAT-only operation?

Yes - when VDD is removed and VBAT is applied, the 4 KB backup SRAM remains powered and fully accessible via the PWR_CR register (DBP bit enabled). Data retention is guaranteed for ≥20 years at 25 °C per ST's characterization, provided VBAT ≥ 1.8 V and proper decoupling is implemented.
