Product details
Overview
STM32F217ZET7 from STMicroelectronics is a high-performance ARM® Cortex®-M3 microcontroller featuring 120 MHz CPU operation, 512 KB Flash, 128+4 KB SRAM, hardware AES/SHA cryptographic acceleration, and integrated 10/100 Ethernet MAC with IEEE 1588v2 support - deployed in industrial gateways requiring secure, real-time networked control.
For engineers reviewing the STM32F217ZET7 datasheet, STM32F217ZET7 pinout, STM32F217ZET7 application, or STM32F217ZET7 equivalent, key selection criteria include dual USB OTG (FS + HS), triple 12-bit ADCs (6 MSPS interleaved), 2× CAN 2.0B, parallel camera interface (DCMI), and 140 I/Os with 5 V tolerance - all within LQFP144 package constraints.
Technical Context
The STM32F217ZET7 implements an ARM Cortex-M3 core with Adaptive Real-time Accelerator (ART™) enabling zero-wait-state execution from Flash at 120 MHz, delivering 150 DMIPS. Its multi-AHB bus matrix concurrently serves CPU, DMA, and peripherals including Ethernet MAC and USB OTG HS/FS controllers.
It integrates dual USB PHYs (on-chip FS + ULPI-capable HS), dedicated Ethernet DMA with MII/RMII, flexible static memory controller (FSMC) for NOR/NAND/PSRAM, and a 8–14-bit parallel DCMI supporting up to 48 MB/s image capture - all managed under a unified NVIC with 84 interrupt channels.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | Higher clock (168 MHz), FPU, no hardware crypto, same LQFP100 pinout but different peripheral mapping (no DCMI, no Ethernet MAC) | Lacks integrated Ethernet and camera interface; requires external PHY and FPGA/ASIC for vision processing | Select when floating-point math dominates and network/camera features are offloaded externally |
| STM32H743ZIT6 | Cortex-M7 @ 480 MHz, dual-core option, crypto, Ethernet, DCMI, but larger LQFP144 footprint with different power sequencing and higher VDDA requirements | Supports richer GUIs and AI inference (CMSIS-NN), but increases BOM cost and thermal design complexity | Choose for next-gen gateways needing >2× performance headroom and future-proof peripheral scalability |
Compared with STM32F217ZET7, STM32F407VGT6 trades integrated connectivity for raw compute and FPU, while STM32H743ZIT6 delivers architectural uplift at higher cost and design effort - making the F217 optimal for cost-sensitive, feature-complete industrial edge nodes.

FAQ
What is the maximum operating temperature for STM32F217ZET7?
The STM32F217ZET7 is qualified for industrial temperature range: –40°C to +105°C ambient. This rating applies to the full LQFP144 package variant and is validated per JEDEC JESD22-A108. Thermal derating begins above 85°C ambient when operating at maximum CPU frequency and peripheral load.
Does STM32F217ZET7 support USB device, host, and OTG simultaneously?
No - the STM32F217ZET7 supports USB OTG FS and USB OTG HS as two independent controllers, each capable of device/host/OTG roles, but only one can be active at a time. The FS and HS PHYs cannot operate concurrently due to shared system resources and clock domain constraints.
How many Ethernet MAC instances does STM32F217ZET7 integrate?
The STM32F217ZET7 integrates exactly one 10/100 Ethernet MAC with dedicated DMA, supporting both MII and RMII physical layer interfaces. It does not include dual MAC or switch functionality - external PHY (e.g., LAN8720A) is required for physical layer connectivity.
Is the DCMI interface on STM32F217ZET7 compatible with MIPI CSI-2 sensors?
No - the DCMI is a parallel 8–14-bit synchronous interface (D0–D13, HSYNC, VSYNC, PCLK) and lacks native MIPI CSI-2 support. Interfacing with MIPI sensors requires an external bridge IC (e.g., TC358743) to convert CSI-2 to parallel format before connection to DCMI pins.
