The 25-WLCSP package (2.1x2.49 mm) is the smallest footprint in the family, built for space-constrained, battery-operated edge nodes: think sensor pods, wearable health monitors, and single-coin-cell IoT endpoints where every square millimeter of board area is budgeted.
Internal oscillator means you can skip the external crystal on cost-sensitive builds.
