32.768 kHz MEMS XO for automotive timing
The MEMS resonator resists vibration and thermal shock better than a quartz tuning fork — useful for engine-bay or chassis-mounted modules that see constant vibration.
Wide supply tolerance and low current draw
Supply voltage spans 1.71 V to 3.63 V, so it runs directly off a 3.3 V or 1.8 V rail without an intermediate regulator — one less part on the BOM. Maximum supply current is 1.19 mA typical — low enough for a battery-backed RTC module that stays alive during vehicle sleep mode.
