The LM3S8930-EQC50-A2: It carries a rich peripheral set including CAN, Ethernet, I²C, SPI, and multiple UARTs, plus a PWM module and brown-out detection.
The 256 KB Flash can hold a moderate application with a network stack and bootloader; the 64 KB SRAM supports packet buffers and a small RTOS.
There is no direct factory replacement listed; the part is available through surplus and independent distribution channels.
The lifecycle record does not list an official replacement. For a pin-compatible alternative within the Stellaris family, a design review would be needed — the LM3S8930 is part of a broad family, but no specific successor order code is provided. Sourcing the original part through independent distribution remains the practical path for existing BOMs.
