For engine-bay applications that see 105°C ambient, check the DSC1001 high-temp variant or the DSC1121 series with extended temperature grades. This 420:1 ratio makes the part viable for battery-backed RTC keep-alive or wake-on-event subsystems where the clock domain must be gated between active periods. For a 1.8432 MHz clock, this translates to a worst-case drift of roughly ±92 Hz — tight enough for UART baud-rate generation and general-purpose MCU clocking, but verify for precision timing or crystal-referenced PLLs. ## Package, footprint, and layout notes Housed in a 4-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm max. The 0.90 mm profile fits under low-clearance shrouds or between stacked PCBs.","metaTitle":"DSC1001BI1-001.8432T — Microchip MEMS XO, 1.8432 MHz","metaDescription":"Microchip DSC1001BI1-001.8432T MEMS oscillator: 1.8432 MHz CMOS output, ±50 ppm stability, -40 to 85°C, AEC-Q100, standby function.","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":"1.8432 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-VDFN","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)":"6.3mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.5400","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/DSC1001BI1-001.8432T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BI1-001.8432T when reusing this data.
