The LM3S800-EQN50-C2T: The 8 KB RAM is enough for modest data buffers but will be tight if you need a TCP/IP stack or a large display frame buffer.
Texas Instruments lists the LM3S800-EQN50-C2T with an active product status.
The two order codes share the same core, memory, and peripheral set. For industrial or outdoor applications where the ambient temperature exceeds 85°C, the -EQN50 variant is the correct choice.
