Why this MEMS oscillator exists on your BOM
Active lifecycle status — Microchip still produces this part, so there is no last-time-buy deadline or forced migration for existing designs.
4-VDFN package, 3.20 mm x 2.50 mm body, 0.90 mm seated height — the 0.50 mm pitch lands are on the bottom, so the reflow profile and pad geometry follow the JEDEC VDFN land pattern. Supply voltage spans 1.7 V to 3.6 V — a 3.3 V or 2.5 V rail works, and the oscillator keeps ±25 ppm frequency stability across the full range.
