The wide supply range of 2.25V to 3.6V lets it run directly from a 2.5V or 3.3V rail without an intermediate regulator, simplifying the power tree in mixed-voltage designs.
Housed in a 6-SMD, no-lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm, the footprint is compatible with standard 2.5x2.0mm oscillator layouts, but the MEMS die eliminates the need for a quartz blank — no start-up delay or crystal load-cap selection.
Yes, it carries an AEC-Q100 rating, meeting the automotive-grade qualification for temperature, reliability, and PPAP compliance.
