The MSP430G2001IN14: 512 bytes of program Flash (512 x 8) and 128 bytes of RAM (128 x 8) limit firmware to a few hundred lines of C or assembly.
For a BOM line, this is the low-risk scenario — you're not hunting surplus stock or scrambling for a drop-in replacement.
Yes, the MSP430G2001IN14 includes an internal oscillator, so no external crystal or ceramic resonator is needed for basic operation. This saves two pins and a couple of passive components on the board.
Within the MSP430G2xx series, the MSP430G2203 is a pin-compatible upgrade with 2 KB Flash and 256 bytes RAM in the same 14-PDIP package. If you need more I/O or a larger package, the MSP430G2553 in a 20-pin DIP or TSSOP offers 16 KB Flash and a full UART. These are all from the same MSP430G2xx family and share the same core architecture and peripheral set.
