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. ## Standby function cuts supply to 15 µA","metaTitle":"DSC1001CI3-012.0000 MEMS Oscillator, 12 MHz, CMOS, AEC-Q100","metaDescription":"DSC1001CI3-012.0000 from Microchip Technology: XO (Standard) MEMS oscillator, 12 MHz CMOS output, ±20 ppm stability, AEC-Q100 qualified, 1.8V-3.3V supply","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1001","Package":"Tube","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"12 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±20ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"8mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1001CI3-012.0000 AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 qualification, making it suitable for automotive-grade applications."},{"question":"What is the closest pin-compatible alternative to DSC1001CI3-012.0000?","answer":"The DSC1001 series includes multiple frequency variants in the same 4-VDFN package with identical supply and temperature ratings — no direct second-source cross is listed, but any DSC1001 part with the same package and frequency footprint is a functional match."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI3-012.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI3-012.0000 when reusing this data.
