16-bit MSP430 core at 16 MHz — what the speed rating means
The 48 general-purpose I/O pins give enough headroom for parallel LCD data buses, keypad matrices, or multiple chip selects. Brown-out detect and POR eliminate external reset supervisor ICs in cost-sensitive builds.
Package and footprint: 64-LQFP
The Tape & Reel option (the 'T' suffix in the order code) is the production-friendly format for automated pick-and-place; Cut Tape is also available for prototype or low-volume builds.
No direct replacement or second-source alternate is documented in the official cross-reference tables, so the BOM should be qualified with this exact order code.
