On-chip brown-out reset and power-on reset protect against glitchy power-up sequences — a common headache in battery-powered designs where the supply ramps slowly. ## Package and board-fit Housed in a 20-pin TSSOP (4.40 mm wide), this is a hand-solderable SMD package — fine for prototype rework or low-volume assembly. The 0.65 mm pitch is forgiving under a magnifier, and the small footprint leaves room on a two-layer board. Tape-and-reel packaging (Cut Tape also available) means it feeds into pick-and-place for production runs, but you can also grab a few loose samples for breadboarding.","metaTitle":"MSP430F2121IPWR MCU, 16-Bit, 4KB Flash, 20-TSSOP","metaDescription":"Texas Instruments MSP430F2121IPWR 16-bit MCU, 16MHz, 4KB flash, 256B RAM, 16 I/O, -40°C to 85°C, 20-TSSOP.
