The LM3S801-EGZ50-C2T: The internal oscillator means you can skip an external crystal for non-critical timing, saving two pins and a bit of BOM cost.
The 48-VFQFN with exposed pad (7x7 mm) is a compact, low-inductance package common on motor-control boards. The exposed pad also provides a solid ground reference for the internal analog and digital circuits.
Yes, it includes an internal oscillator, so you can run the core without an external crystal for non-critical timing. This saves two I/O pins and reduces BOM count.
