Operating from 1.8V to 3.3V, this single oscillator covers 1.8V, 2.5V, and 3.3V logic rails — a BOM simplification when the same clock feeds a mixed-voltage system. The 6.3 mA max supply current is the full-load draw at 18.432 MHz; in standby the oscillator sinks 15 µA. Housed in a 4-SMD, no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, the footprint is compatible with standard 5.0×3.2 mm oscillator land patterns. No direct pin-compatible second source is documented, but the DSC1001 series includes multiple frequency and stability variants sharing the same package and pinout.","metaTitle":"DSC1001BI2-018.4320T MEMS Oscillator – Microchip, 18.432 MHz","metaDescription":"Microchip DSC1001BI2-018.4320T XO (Standard), CMOS output, 18.432 MHz, ±25 ppm stability, AEC-Q100 qualified, -40°C to +85°C.","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":"18.432 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":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"6.3mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9750","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BI2-018.4320T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BI2-018.4320T when reusing this data.
