16-bit MSP430 core with 16KB Flash — what the specs mean for your firmware
It runs at 16 MHz and packs 16 KB of Flash program memory (16K x 8) with 512 x 8 bytes of RAM — enough for modest sensor-fusion or control loops in battery-operated gear.
Official production has ended; there is no last-time-buy window still open.
Package and footprint — 49-DSBGA
Housed in a 49-ball DSBGA (2.8 x 2.8 mm) — a fine-pitch wafer-level chip-scale package. This footprint demands careful PCB layout: the solder-mask-defined pads need a stencil aperture matched to the 0.4 mm pitch. The small body saves board area but makes hand-rework impractical; expect to use a reflow oven with a profile tuned for lead-free solder.
