Active current is 7.2 mA max at 27 MHz; when the Standby (Power Down) pin is asserted, the disable current drops to 15 µA max — this 480× reduction lets the system sleep for days on a coin cell while keeping the oscillator ready to wake on a threshold event. ## Package and PCB layout notes The 4-pin footprint is compatible with standard quartz oscillator layouts, so a board originally designed for a quartz XO can often accept this MEMS part without a respin — confirm the pin 1 orientation and the disable pin mapping against the existing footprint. No official second source or direct replacement is published — the DSC1001 series is the only family carrying this exact frequency and grade combination.","metaTitle":"DSC1001AI2-027.0000 MEMS XO – 27 MHz, AEC-Q100, CMOS","metaDescription":"Microchip DSC1001AI2-027.0000: 27 MHz MEMS XO, CMOS output, ±25 ppm stability, 1.8V–3.3V supply, AEC-Q100, standby mode.","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":"27 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C ~ 85°C","Current - Supply (Max)":"7.2mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does DSC1001AI2-027.0000 support a 1.8V supply?","answer":"Yes, the supply voltage range is 1.8V to 3.3V, so it operates directly on a 1.8V rail without an external regulator."},{"question":"What is the standby mode current consumption?","answer":"When the Standby (Power Down) function is active, the disable current is 15 µA max — a 480× reduction from the 7.2 mA active current."},{"question":"Is DSC1001AI2-027.0000 AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 rating, meaning it has passed automotive-grade reliability testing for temperature, ESD, and mechanical stress."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001AI2-027.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001AI2-027.0000 when reusing this data.
