Buyers should verify date codes and request counterfeit screening for any units sourced outside the authorized channel.
MSL level should be confirmed from the date-code-specific datasheet revision before reflow.
No official pin-compatible replacement is listed in the Texas Instruments records for this exact order code. The Stellaris family has been superseded by the Tiva C Series (TM4C) and other ARM Cortex-M4 families, but those are not drop-in replacements. For a pin-compatible alternative, buyers should evaluate the remaining Stellaris 9000-series variants still available through surplus channels.
Yes, this MCU integrates an Ethernet MAC+PHY controller, along with USB OTG, CAN, and multiple serial interfaces. It is designed for networked control applications.
