The LM3S6C65-IQC80-A1: The 100-LQFP package with 46 general-purpose I/O keeps routing manageable on a two-layer board.
The 100-LQFP (14x14 mm) package has a fine pitch suitable for rework with a hot-air station. The internal oscillator allows operation without an external crystal for UART baud-rate generation.
Within the Stellaris 6000 series, pin-compatible density variants exist — the same 100-LQFP footprint carries different Flash/RAM combinations. The base product number LM3S6C65 identifies this specific 512 KB / 64 KB configuration. For a drop-in alternate with the same pinout, check the LM3S6xxx family in the same package; the exact order code determines the memory size and peripheral set.
