12 MHz MEMS oscillator with ±20 ppm stability for automotive timing
AEC-Q100 qualification (Grade 2 implied by the temperature range) means this part is production-qualified for automotive applications — under-hood ECU, cabin infotainment, ADAS sensor modules — where a quartz crystal's vibration sensitivity or aging drift would be a risk. Supply voltage spans 1.8V to 3.3V, so the same BOM line works across a 3.3V legacy bus and a 1.8V core rail without a separate level translator — simplifies the power tree and reduces component count.
Active production, no LTB — design-in ready
Product status is Active per Microchip's current lifecycle record — no last-time-buy window, no NRND flag. The DSC1001 series remains a supported design-in choice for new automotive and industrial builds.
Housed in a 4-VDFN package measuring 3.20mm × 2.50mm (0.126" × 0.098") with a seated height of 0.90mm — the same footprint as many quartz crystal oscillators, so it drops into existing pads without a board spin.
