The MSP430F2101TPW: It carries 1 KB of program Flash and 128 bytes of RAM. The 16 general-purpose I/O pins and integrated Slope A/D converter handle basic analog sensing without an external ADC.
The 20-TSSOP package (4.40 mm width) is a common surface-mount footprint shared across the MSP430F2xx value-line options.
The two parts share the same MSP430 CPU16 core, 1 KB Flash, and 128 B RAM. The key difference is the package: MSP430F2101TPW is a 20-TSSOP, while MSP430F2101IRHB is a 32-QFN with additional I/O and a different footprint. The TSSOP variant is the lower-cost, smaller-board-area option for designs that do not need the extra pins.
