Product details
Overview
STM32F207IEH6TR from STMicroelectronics is a high-performance Arm® Cortex®-M3 microcontroller featuring 120 MHz CPU, 512 KB Flash, 128+4 KB SRAM, dual CAN 2.0B interfaces, 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and USB OTG HS/FS - deployed in industrial gateways requiring real-time protocol bridging, deterministic networking, and multi-interface concurrency.
For engineers reviewing the STM32F207IEH6TR datasheet, STM32F207IEH6TR pinout, STM32F207IEH6TR application, or STM32F207IEH6TR equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN arbitration latency, DCMI camera interface bandwidth (up to 48 MB/s), ART Accelerator™ zero-wait-state Flash execution, and VBAT-backed RTC with 20×32-bit registers for secure time-stamped logging.
Technical Context
The STM32F207IEH6TR integrates a dual-bus AHB matrix enabling concurrent access to Flash, SRAM, and peripherals - critical for simultaneous Ethernet packet processing, CAN message filtering, and SDIO-based storage I/O without bus contention. Its ART Accelerator™ eliminates Flash wait states at 120 MHz, while the dedicated Ethernet DMA supports scatter-gather descriptors and IEEE 1588v2 timestamping in hardware.
It features three independent 12-bit ADCs (up to 6 MSPS in triple interleaved mode), two 12-bit DACs, and a true random number generator (RNG) - supporting sensor fusion, analog control loop closure, and cryptographic key generation within a single chip. The flexible static memory controller (FSMC) supports NAND/NOR/PSRAM with ECC and 8080/6800 LCD interface modes.

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 CPU speed (168 MHz), FPU, no Ethernet MAC - uses external PHY; 1 MB Flash, same LQFP100 package. | Lacks integrated 10/100 MAC and IEEE 1588v2 hardware - unsuitable for time-sensitive industrial Ethernet nodes. | Select when floating-point math dominates workload and Ethernet is implemented via external PHY + software stack. |
| STM32H743ZIT6 | Dual-core (Cortex-M7/M4), 480 MHz, 2 MB Flash, 1 MB RAM, dual Ethernet MAC, but LQFP144 package limits I/O count vs. LQFP176. | Higher performance but larger die size and higher active power - increases thermal design complexity in space-constrained gateways. | Select only when >200 DMIPS and dual-core RTOS partitioning are required; not drop-in compatible due to pinout and power sequencing differences. |
Compared with STM32F207IEH6TR, the STM32F407VGT6 trades integrated Ethernet for FPU and higher clock speed, while the STM32H743ZIT6 adds dual-core capability at the cost of pin compatibility and thermal headroom - making the F207 optimal for cost-sensitive, Ethernet-centric industrial edge nodes needing proven maturity and full peripheral integration.

FAQ
What is the maximum operating frequency of the STM32F207IEH6TR's CPU core?
The STM32F207IEH6TR features an Arm Cortex-M3 core rated for up to 120 MHz operation. This frequency is sustained with zero wait states in Flash execution thanks to the ART Accelerator™, and it delivers 150 DMIPS (Dhrystone 2.1). The core includes a Memory Protection Unit (MPU) and supports Thumb-2 instruction set for code density and efficiency.
Does the STM32F207IEH6TR support hardware IEEE 1588v2 timestamping?
Yes - the integrated 10/100 Ethernet MAC includes dedicated hardware timestamping logic compliant with IEEE 1588v2. It captures precise transmit/receive timestamps at the MAC layer with sub-microsecond resolution, enabling accurate time synchronization in industrial automation and power grid monitoring without external timing ICs or software overhead.
How many I/O pins are 5 V-tolerant on the LQFP176 package?
All 138 general-purpose I/O pins on the STM32F207IEH6TR in LQFP176 package are 5 V-tolerant when configured in input, output, or alternate function modes - verified per STMicroelectronics datasheet DS6329 Rev 18 Section 6.3.16. This allows direct interfacing with legacy 5 V logic, RS485 transceivers, and industrial sensors without level shifters.
What is the purpose of the Flexible Static Memory Controller (FSMC) in this MCU?
The FSMC provides direct parallel bus access to external memories including NOR/NAND flash, PSRAM, and SRAM, as well as 8080/6800-mode LCD panels. It supports wait-state insertion, byte/halfword/word access, and hardware ECC for NAND - enabling local HMI frame buffers, firmware expansion storage, and legacy display interfaces without external glue logic.
