The 10 general-purpose I/O pins and integrated peripherals (brown-out detect, POR, PWM, WDT) keep the BOM count low for battery-operated or space-constrained designs.
2 KB Flash and 128 bytes RAM — sizing the firmware budget
The 2 KB Flash (2K x 8 plus 256 bytes) is the entire program store — there is no external memory bus. That means the firmware image must fit within 2 KB, including any bootloader, calibration constants, and interrupt vectors. The 128 x 8 RAM is the working memory; stack depth, buffer allocation, and global variables all share this space. For designs that need more headroom, the MSP430F2xx family offers pin-compatible parts with up to 8 KB Flash and 512 bytes RAM in the same 14-TSSOP footprint, but the programmer and toolchain stay identical.
Industrial temperature range and active lifecycle
The lifecycle status is Active, meaning Texas Instruments continues to manufacture it — no PCN or last-time-buy notice is in effect. ROHS3 compliance is confirmed, so it passes into EU and RoHS-restricted markets without exemption paperwork.
14-TSSOP surface-mount footprint
The slope A/D converter is an integrated data converter for slow-varying analog signals — useful for temperature or battery monitoring without an external ADC.
