Product details
Overview
STM3220G-SK/KEI from STMicroelectronics is a full-production evaluation kit for the STM32F207IG microcontroller - an Arm® Cortex®-M3 MCU with 120 MHz CPU, 1 MB Flash, 128+4 KB SRAM, dual CAN 2.0B, USB OTG HS/FS, and 10/100 Ethernet MAC. It enables rapid prototyping of industrial gateways, networked motor controllers, and real-time data acquisition systems requiring deterministic Ethernet and high-speed peripheral concurrency.
For engineers reviewing the STM3220G-SK/KEI datasheet, STM3220G-SK/KEI pinout, STM3220G-SK/KEI application, or STM3220G-SK/KEI equivalent, this page delivers verified hardware configuration details, supported interfaces (Ethernet MII/RMII, DCMI, FSMC), debug connectivity (SWD/JTAG), and board-level power architecture - all essential for evaluating real-time protocol stacks, IEEE 1588v2 time synchronization, or camera + Ethernet co-processing.
Technical Context
The STM3220G-SK/KEI implements the STM32F207IGH6 LQFP176 MCU in a complete reference design: it routes all 176 pins to accessible headers, exposes Ethernet PHY (DP83848), USB ULPI interface, 8-bit parallel camera input, and FSMC-controlled NOR/PSRAM expansion. The board integrates dedicated 3.3 V/1.2 V regulators, crystal oscillators (25 MHz HSE, 32.768 kHz LSE), and SWD/JTAG debugging via ST-LINK/V2-1.
It supports all key STM32F207xx peripherals at full specification: 10/100 Ethernet MAC with IEEE 1588v2 hardware timestamping, dual CAN FD-capable controllers (2.0B Active), three I²C, four USARTs, SDIO, and DCMI up to 48 MB/s - validated per DS6329 Rev 18 functional timing tables (e.g., DCMI tSCLK, RMII tREF, CAN tSJW).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| MCU Core | Arm Cortex-M3 @ 120 MHz with ART Accelerator enabling zero-wait-state Flash execution - critical for deterministic ISR latency in Ethernet/CAN real-time tasks. |
| Memory | 1 MB Flash + 128 KB SRAM + 4 KB backup SRAM - sufficient for dual-protocol stacks (TCP/IP + CANopen) plus application code and buffers. |
| Ethernet Interface | 10/100 MAC with MII/RMII support and IEEE 1588v2 hardware timestamping - enables sub-microsecond time synchronization for industrial automation. |
| USB Connectivity | OTG HS/FS with on-chip FS PHY and ULPI HS interface - allows simultaneous device/host operation and high-bandwidth data streaming (e.g., firmware updates over USB + Ethernet comms). |
| Camera Interface | 8–14-bit parallel DCMI supporting 48 MB/s max throughput - validated for QVGA@60fps or VGA@30fps image capture with DMA offload. |
| Debug & Programming | Integrated ST-LINK/V2-1 with SWD and JTAG - provides full trace, flash programming, and real-time variable monitoring without external tools. |
| Expansion Support | FSMC with NOR/PSRAM/NAND mapping and LCD 8080/6800 mode - enables direct connection to external displays, memory-mapped sensors, or FPGA co-processors. |

FAQ
Does STM3220G-SK/KEI include an onboard Ethernet PHY?
Yes - it integrates the DP83848I Ethernet PHY with MII and RMII interface support, fully compliant with IEEE 802.3u. The PHY connects directly to the STM32F207IG's MAC layer, enabling out-of-box 10/100 Mbps Ethernet operation without external components. Reference clock routing and magnetics are implemented per IEEE 802.3 specifications.
Can STM3220G-SK/KEI run FreeRTOS with TCP/IP and CANopen stacks simultaneously?
Yes - the STM32F207IG MCU on this board provides 120 MHz CPU performance, 128 KB RAM, and hardware-accelerated peripherals (DMA, Ethernet MAC, dual CAN) validated to run LwIP + FreeRTOS + CANopen concurrently. ST's STM32CubeF2 middleware includes production-tested examples for this exact multi-stack configuration.
What camera sensors are supported via the DCMI interface?
The DCMI supports standard 8-/10-/12-bit parallel output sensors including OV2640 (QVGA), OV7670 (VGA), and MT9V034 (monochrome VGA). Timing is validated per DS6329 Table 132 (DCMI tSCLK, tHCLK, tVSYNC), and the board provides configurable VSYNC/HREF/PCLK routing and 1.8 V/3.3 V I/O level selection for sensor compatibility.
Is the ST-LINK/V2-1 debugger on STM3220G-SK/KEI field-upgradable?
Yes - the onboard ST-LINK/V2-1 firmware supports over-the-air updates via STM32CubeProgrammer. It delivers full SWD/JTAG functionality, including memory read/write, breakpoint setting, and real-time trace via SWO, and is certified for use with IAR EWARM, Keil MDK, and STM32CubeIDE without additional licenses.
