The standby (power-down) function on pin 1 drops the supply current to 15 µA max, which is the difference between a module that drains the battery overnight and one that passes the OEM's quiescent-current spec. ## Supply voltage tolerance and current budget The supply voltage range spans 1.8V to 3.3V — a single BOM line can serve a 1.8V-core MCU on one board and a 3.3V peripheral on another without a separate oscillator variant. Maximum operating current is 7.2 mA at the highest frequency and supply; in standby the part draws 15 µA max, so a CAN transceiver or ignition-switched module can leave the oscillator powered continuously without exceeding the sleep-mode budget. ## Package and mounting for production Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many 5x3.2 mm XO footprints, so a board layout for a quartz oscillator often accepts this MEMS part without a pad change. Supplied on tape and reel (TR) for automated pick-and-place; the MEMS die inside is inherently more shock- and vibration-tolerant than a quartz crystal, which matters for engine-bay and transmission-mounted electronics. New designs can commit to this part without a near-term migration risk.","metaTitle":"DSC1001BI1-066.6666T MEMS XO, 66.6666 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001BI1-066.6666T: 66.6666 MHz MEMS oscillator, CMOS output, ±50 ppm stability, 1.8-3.3 V supply, AEC-Q100 qualified.","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":"66.6666 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±50ppm","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1001BI1-066.6666T AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 ratings, which means it passed the automotive-grade qualification suite: temperature cycling, ESD, latch-up, and extended life tests.
