Operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails. The wide voltage range simplifies use across multi-rail designs without a separate regulator for the oscillator.
Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The no-lead construction requires a solder-paste stencil with aperture matching the pad geometry.
Yes, it carries AEC-Q100 qualification, which covers the reliability stress and temperature-grade requirements for automotive ICs. The -55°C to 125°C range supports under-hood and cabin environments.
The MEMS resonator offers better shock and vibration tolerance than a quartz crystal.
