The DSC6121CE2A-00CU: Typical supply current is 3mA max — a low-power figure that matters for battery-operated designs. At 32.768MHz with a CMOS output, the dynamic current scales with frequency and load capacitance; the 3mA typ gives a realistic ceiling for the oscillator core, not the output buffer driving a heavy trace. The ±25ppm stability holds across the full 1.71V–3.63V supply range — the MEMS resonator's pullability is negligible compared to a quartz crystal, so the frequency doesn't shift with supply droop.
