The 8 KB SRAM is enough for moderate data buffers and context storage; if your application needs DMA-driven peripherals or larger frame buffers, you'll want to check the SRAM budget early. The internal oscillator reduces external BOM count, but for precision timing over temperature you may still add a crystal.
Package and thermal: 48-VQFN with exposed pad
Without that, junction temperature climbs fast above 400 mA continuous I/O load. The supplier device package is 48-VQFN (7x7) — same footprint as many Stellaris siblings, so a board layout can often be reused across the family.
