Supply voltage spans 2.25 V to 3.6 V, covering the common 2.5 V, 3.0 V, and 3.3 V logic rails without an external LDO — the oscillator runs directly off the MCU's I/O bank supply. 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 footprint matches the standard 3.2 x 2.5 mm MEMS oscillator land pattern — no board spin if you are swapping from a quartz XO of the same size.
Yes — AEC-Q100 qualification is listed on the part. That means it has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up, and extended life) required for under-hood and cabin electronics.
