It delivers ±10 ppm frequency stability across the full -40 to 105 °C range — this is the AEC-Q100 Grade 1 temperature band, meaning the part holds timing through under-hood heat soak and cold-crank dips without the warm-up drift of a quartz crystal. Supply voltage spans 1.8 V to 3.3 V, so the same order code serves a 1.8-V core rail and a 3.3-V I/O rail without a separate regulator. ## Package and board-fit for 4-SMD no-lead Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm max. The 0.098\" x 0.079\" footprint is the same as standard 2.5 x 2.0 mm quartz oscillators — a layout already using that land pattern accepts this MEMS part without a board spin. The base product number DSC1001 covers the series — this suffix denotes the specific frequency and stability grade.","metaTitle":"DSC1001DL5-018.4320T MEMS Oscillator – 18.432 MHz, AEC-Q100","metaDescription":"Microchip DSC1001DL5-018.4320T, XO (Standard) 18.432 MHz CMOS MEMS oscillator.

The CMOS output and 1.8-3.3 V supply range match typical quartz XO footprints and logic levels. The key difference is the MEMS resonator — it does not require a load capacitor or start-up time, and the ±10 ppm stability holds over temperature without the aging drift of quartz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DL5-018.4320T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DL5-018.4320T when reusing this data.
