It operates across a 1.8 V to 3.3 V supply range, so the same BOM line serves both 1.8 V core and 3.3 V I/O domains without a secondary regulator.
Automotive qualification and standby function
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm x 0.90 mm, the footprint matches standard 3.2 x 2.5 mm XO land patterns — no layout change from a quartz-based sibling. Maximum supply current is 7.2 mA during active operation — the thermal dissipation in a 3.2 x 2.5 mm package is negligible, so no special copper pour or via array is needed.
