Rated across -40°C to 85°C with ±25 ppm frequency stability, it holds the clock tight through an engine-bay thermal cycle or a factory-floor temperature swing. Operates from a 1.8V to 3.3V supply rail — the same BOM line serves both a 1.8V-core SoC and a 3.3V peripheral bus without a separate regulator. Active current draw is 7.2 mA max at 66.66 MHz — the MEMS resonator consumes less than a comparable quartz oscillator at the same frequency, which matters for thermally constrained enclosures. This is a current-design-in part, not a sunsetted line. Supplied in Tape & Reel (TR) for automated pick-and-place; the 4-SMD, No Lead Exposed Pad package (7.00mm x 5.00mm footprint) is a standard oscillator land pattern — no board spin needed if you're migrating from a quartz can.","metaTitle":"DSC1001AI2-066.6600T MEMS Oscillator","metaDescription":"Microchip DSC1001AI2-066.6600T — 66.66 MHz XO, CMOS output, ±25 ppm stability, -40°C to 85°C, AEC-Q100.
