Product details

Overview

STR910-EVAL from STMicroelectronics is an evaluation board for the STR91xF series of ARM966E-S™-based microcontrollers, supporting USB 2.0 Full-Speed device/host/OTG operation, 10/100 Ethernet MAC, and dual CAN 2.0B controllers. It includes on-board 8 MB SDRAM, 2 MB Flash, and a JTAG/SWD debug interface.

For engineers reviewing the STR910-EVAL datasheet, STR910-EVAL pinout, STR910-EVAL application, or STR910-EVAL equivalent, this board enables rapid validation of real-time industrial control, networked sensor gateway, and USB-connected embedded HMI designs with full peripheral access and debug visibility.

Technical Context

The STR910-EVAL platform interfaces directly with the STR912FZ2M4 or STR912FAW4 MCU, exposing all 144 LQFP pins via expansion headers. It integrates a DP83848C PHY for MII/RMII Ethernet connectivity and MCP2551 transceivers for both CAN channels, with configurable termination and loopback support.

Power is managed through a dual-rail DC-DC converter (3.3 V/1.8 V) synchronized to the MCU's voltage requirements, and USB VBUS detection logic enables automatic host/device mode selection during enumeration.

Key Specifications

Parameter	Value and Actual Design Meaning
MCU Core	ARM966E-S @ 96 MHz - delivers deterministic real-time execution with TCM and MMU support for RTOS-based applications.
Memory	8 MB SDRAM + 2 MB Flash - sufficient for bootloaders, protocol stacks (TCP/IP, CANopen), and application firmware with runtime data buffers.
Ethernet Interface	10/100 Mbps MII/RMII with DP83848C PHY - enables direct connection to switches or PHY-less PHY modules without external magnetics in RMII mode.
CAN Channels	Dual CAN 2.0B controllers with MCP2551 transceivers - supports distributed control networks with simultaneous bus monitoring and message filtering.
USB Support	Full-Speed (12 Mbps) device/host/OTG via integrated transceiver and ULPI interface - allows seamless firmware updates, HID emulation, and peripheral attachment.
Debug Interface	JTAG/SWD header compatible with ST-LINK/V2 and third-party debug probes - provides non-intrusive breakpointing, memory inspection, and flash programming.

FAQ

Does STR910-EVAL support CAN FD?

No. The STR910-EVAL implements two classical CAN 2.0B controllers with MCP2551 transceivers, limited to 1 Mbps baud rate and standard 11-bit identifiers. CAN FD requires hardware-level controller and transceiver upgrades not present on this board or its target MCU.

Can I replace the onboard STR912FZ2M4 with a STR912FAW4?

Yes. Both MCUs share identical 144-pin LQFP packaging, pinout, and peripheral mapping. The STR912FAW4 substitutes 256 KB SRAM for the FZ2M4's 96 KB, enabling larger real-time buffers and multi-threaded RTOS workloads without board modification.

Is Ethernet operation functional without external magnetics?

Yes, in RMII mode only. The board routes RMII signals directly to the DP83848C PHY, which supports direct connection to RJ45 jacks with integrated magnetics. MII mode requires external 74LVC245 level-shifting and discrete magnetics.

What debug tools are officially supported?

ST-LINK/V2 and ST-LINK/V2-1 are fully supported for SWD/JTAG debugging and flash programming. Third-party tools including Segger J-Link and IAR Embedded Workbench are compatible via OpenOCD or vendor-specific drivers, with verified initialization sequences for the STR91x memory map.
