MEMS oscillator for low-frequency automotive timing
Rated AEC-Q100, this part targets automotive applications that require a low-frequency reference — such as wake-up timers, watchdog clocks, or CAN bus keep-alive — where a quartz crystal's shock sensitivity or size would be a liability. The 4-VLGA package (2.50 mm × 2.00 mm) and wide supply range of 1.71 V to 3.63 V let it drop into a 1.8 V or 3.3 V domain without a level translator.
AEC-Q100 qualification covers the reliability stress and PPAP requirements, but the thermal envelope limits this part to cabin or climate-controlled modules, not under-hood or engine-bay ECUs. For a 40 kHz reference, the ±20 ppm stability translates to roughly ±0.8 Hz drift across temperature — well within the tolerance of a low-speed wake-up timer or a CAN bus bit-time calibration.
