For an ECU that must clock the CAN controller within 2 ms of power-on, that matters. The 105°C ceiling covers the ambient near the exhaust manifold or turbocharger — a quartz oscillator at that temperature would drift outside ±25 ppm without temperature compensation; the MEMS die holds the frequency within the same window. The part is current for new designs and volume builds. Operates from any supply between 1.8V and 3.3V — no separate regulator needed if the core rail is 1.8V or the I/O rail is 3.3V. The 7.2 mA max active current is typical for a 27 MHz CMOS output at 3.3V; at 1.8V the draw drops proportionally. ## 4-SMD no-lead — standard 7.0 x 5.0 mm footprint The footprint matches the industry-standard 7x5 oscillator land pattern — a drop-in replacement for quartz XOs in the same size, no board spin needed. Supplied on Tape & Reel (TR) — 1000 or 3000 pieces per reel depending on the reel diameter, ready for automated pick-and-place without a tray change.","metaTitle":"DSC1001AL2-027.0000T 27 MHz MEMS XO, AEC-Q100, ±25 ppm","metaDescription":"Microchip DSC1001AL2-027.0000T — 27 MHz MEMS XO, CMOS output, ±25 ppm stability, 1.8V–3.3V supply, -40°C to +105°C, 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":"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~105°C","Current - Supply (Max)":"7.2mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the frequency tolerance of DSC1001AL2-027.0000T?","answer":"This is the total accuracy including initial tolerance, temperature drift, and supply sensitivity — no separate calibration needed."},{"question":"Where can I purchase DSC1001AL2-027.0000T in tape and reel?","answer":"Sourced to order against your BOM quantity through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001AL2-027.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001AL2-027.0000T when reusing this data.
