The no-lead land pattern is straightforward for a standard reflow profile; no via-in-pad or buried-via fan-out required. Supply current maxes at 6.3 mA during active oscillation and drops to 15 µA when the standby (power-down) function is asserted. That 15 µA disable current is low enough to leave the oscillator powered from a battery-backed rail without draining the cell — relevant for always-on modules that need to wake on a timer.","metaTitle":"DSC1001DE2-012.0000T – Microchip MEMS XO, 12 MHz, CMOS","metaDescription":"Microchip DSC1001DE2-012.0000T: MEMS XO, 12 MHz, CMOS output, ±25 ppm stability, 1.8V–3.3V supply, AEC-Q100 rated.","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":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"12 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"6.3mA","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":"What is the output type of the DSC1001DE2-012.0000T?","answer":"CMOS output. The oscillator drives a standard CMOS load — no level translation needed if the downstream device accepts 1.8V to 3.3V logic levels."},{"question":"Is the DSC1001DE2-012.0000T rated for automotive temperature range?","answer":"The part is AEC-Q100 qualified, but its specified operating temperature is -20°C to 70°C (commercial grade). For automotive applications requiring -40°C to +125°C, look at the DSC1001 family variants with the appropriate temperature suffix."},{"question":"Can the DSC1001DE2-012.0000T operate from a 1.8V supply?","answer":"Yes. The supply voltage range is 1.8V to 3.3V, so it runs directly from a 1.8V rail without a separate regulator."},{"question":"How does a MEMS oscillator differ from a quartz crystal oscillator?","answer":"A MEMS oscillator uses a silicon micro-electromechanical resonator instead of a quartz crystal. The MEMS resonator is fabricated with semiconductor processes, giving faster startup (microseconds vs milliseconds), better shock/vibration tolerance, and no crystal aging drift. The trade-off is typically tighter frequency stability (±25 ppm here) versus quartz's sub-±10 ppm in some high-end parts."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DE2-012.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DE2-012.0000T when reusing this data.
