For a design that must pass FCC or CE radiated-emissions limits, this can reduce the need for shielding or ferrite beads on the clock trace. Typical current draw is 3 mA — low enough for battery-powered edge nodes where every microamp counts. The MEMS resonator's lower drive current versus a quartz oscillator contributes to this figure. ## Package footprint and assembly fit The 2.00mm x 1.60mm 4-SMD no-lead package (0.90mm seated height) fits into compact PCB layouts where board real estate is at a premium.","metaTitle":"Microchip DSC6331MI1BA-027.0000T XO, 27 MHz, LVCMOS","metaDescription":"Microchip DSC6331MI1BA-027.0000T XO (Standard), 27 MHz, LVCMOS output, MEMS resonator, 1.8V-3.3V supply, -40°C to +85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVCMOS","Series":"DSC63XX","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"-","Function":"-","Frequency":"27 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.079\\\" L x 0.063\\\" W (2.00mm x 1.60mm)","Voltage - Supply":"1.8V ~ 3.3V","Frequency Stability":"-","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"3mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"±0.50%, Center Spread","Current - Supply (Disable) (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa5b6a8e8937569172b185c4e41f3fa9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output logic and supply voltage range for the DSC6331MI1BA-027.0000T?","answer":"This allows direct connection to 1.8V or 3.3V digital logic without external level translation."},{"question":"What temperature range does the DSC6331MI1BA-027.0000T support?","answer":"This covers outdoor, factory-floor, and automotive cabin environments."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC6331MI1BA-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/DSC6331MI1BA-027.0000T when reusing this data.
