Product details
Overview
STM32F207IGT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M3 microcontroller with 1 MB Flash, 128 + 4 KB SRAM, 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, deterministic networking, and multi-interface edge processing.
For engineers reviewing the STM32F207IGT6 datasheet, STM32F207IGT6 pinout, STM32F207IGT6 application, or STM32F207IGT6 equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN bus arbitration capability, ART Accelerator™-enabled zero-wait-state Flash execution at 120 MHz, and 140 I/Os with 5 V tolerance for mixed-voltage system interfacing.
Technical Context
The device integrates a dual-bus AHB matrix enabling concurrent access to Flash, SRAM, and peripherals - critical for simultaneous Ethernet packet handling, CAN message buffering, and camera interface streaming without bus contention. Its ART Accelerator™ eliminates Flash wait states by caching instruction fetches and branch prediction, sustaining 150 DMIPS at 120 MHz.
Hardware-accelerated IEEE 1588v2 timestamping is implemented directly in the Ethernet MAC logic, supporting sub-microsecond time synchronization for industrial automation. The dual USB OTG controllers operate independently: one with on-chip full-speed PHY (OTG_FS), the other with ULPI interface and dedicated DMA for high-speed (480 Mbps) host/device operation (OTG_HS).

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-connectivity MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | Higher clock (168 MHz), FPU, no Ethernet MAC; adds FMC but removes IEEE 1588v2 hardware timestamping | Suitable for compute-intensive DSP tasks but lacks native Ethernet timing for industrial automation | Select when floating-point math dominates over deterministic network timing requirements |
| STM32H743ZIT6 | Dual-core (Cortex-M7/M4), 480 MHz, 2 MB Flash, integrated Ethernet PHY option, no DCMI | Targeted at high-throughput AI inference at edge; replaces external PHY but drops camera interface | Choose for advanced HMI or ML workloads where camera input is unnecessary and dual-core coordination is required |
Compared with STM32F207IGT6, the F407VGT6 trades Ethernet determinism for raw compute throughput and FPU, while the H743ZIT6 shifts focus to heterogeneous processing and integrated PHY - neither replicates the precise balance of 120 MHz real-time control, dual CAN, IEEE 1588v2, and DCMI found in the F207IGT6.

FAQ
Does STM32F207IGT6 support hardware encryption?
No, STM32F207IGT6 does not include dedicated cryptographic accelerators (AES, SHA, PKA). It relies on software libraries for encryption; security-critical applications require external secure elements or migration to STM32L4+/H7 series with CryptoCell or AES engines.
What is the maximum operating temperature for LQFP176 package?
The STM32F207IGT6 in LQFP176 package is rated for industrial temperature range: –40 °C to +105 °C ambient. Thermal resistance θJA is 24.5 °C/W; derating applies above 85 °C ambient under full 120 MHz load with all peripherals active.
Can the Ethernet MAC operate without an external PHY?
No. The STM32F207IGT6 implements only the Media Access Control (MAC) layer. An external PHY chip (e.g., LAN8720A, DP83848) is mandatory for physical layer signaling (10/100BASE-TX), MII/RMII interface, and auto-negotiation.
Is the DCMI interface compatible with MIPI CSI-2 sensors?
No. The DCMI is a parallel 8–14-bit synchronous interface (ITU-R BT.601/656, CCIR656). MIPI CSI-2 requires serialized differential signaling and dedicated D-PHY layers - incompatible without bridge ICs like AP0101 or MAX96705.
