For a battery-backed RTC or wake-up timer, that 15 µA leakage is low enough to keep the oscillator off during sleep without draining the coin cell. It does not extend to the 125°C under-hood ambient that AEC-Q100 Grade 0 parts handle; if the oscillator sits near the engine block or exhaust, you need a Grade 0 part. The ±50 ppm frequency stability is tight enough for a CAN bus or Ethernet PHY reference, but not for a precision GPS or cellular PLL — those typically require ±25 ppm or better. The 4-SMD, No Lead package with 5.00mm x 3.20mm footprint is a standard MEMS oscillator land pattern; no special fan-out or via-in-pad required.","metaTitle":"DSC1001BI1-004.0000T MEMS Oscillator – AEC-Q100, 4 MHz, CMOS","metaDescription":"Microchip DSC1001BI1-004.0000T XO (Standard) MEMS oscillator, 4 MHz CMOS output, AEC-Q100 qualified, -40°C to 85°C, 1.8V-3.3V supply.

The AEC-Q100 qualification confirms it has passed the same reliability stress tests (temperature cycling, ESD, latch-up) that quartz automotive oscillators undergo."},{"question":"How do I enable standby mode on the DSC1001BI1-004.0000T?","answer":"The standby (power-down) function is typically controlled by a dedicated pin on the oscillator — pulling that pin low (or high, depending on the logic) shuts down the output and drops the supply current to 15 µA max. Consult the DSC1001 datasheet for the exact pin assignment and logic threshold; the standby pin is not a standard CMOS I/O and must be driven to the correct level."},{"question":"Is the DSC1001BI1-004.0000T RoHS compliant and lead-free?","answer":"The evidence does not explicitly list RoHS compliance or lead-free status. Microchip's DSC1001 series is generally RoHS-compliant and lead-free, but confirm the specific date code and certificate of compliance with your supplier at RFQ — do not assume without verification."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BI1-004.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BI1-004.0000T when reusing this data.
