AEC-Q100 qualification confirms it passes automotive-grade reliability stress: temperature cycling, ESD, and latch-up. Supply voltage spans 1.8V to 3.3V, so the same part can serve a 1.8V MCU core clock and a 3.3V peripheral bus without a level translator — a BOM simplification for multi-rail designs. Active draw is 8 mA max at 28.6363 MHz. For a battery-backed RTC or sleep-mode controller, the standby current is low enough to avoid draining a coin cell over months. Housed in a 4-VDFN package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm max. The 4-pin footprint has a centre ground pad — the PCB layout should include a thermal via under the pad to improve solder-joint reliability during reflow and to keep the MEMS die temperature stable. Product status is Active.","metaTitle":"DSC1001CI1-028.6363T Microchip MEMS XO 28.6363 MHz CMOS","metaDescription":"DSC1001CI1-028.6363T — Microchip DSC1001 series MEMS XO, 28.6363 MHz, CMOS output, AEC-Q100, -40°C to 85°C, 1.8V-3.3V supply.

The 4-VDFN package is lead-free and compatible with standard lead-free reflow profiles. No separate RoHS certificate is needed for BOM compliance."},{"question":"What is the closest pin-compatible alternative to DSC1001CI1-028.6363T?","answer":"Within the same DSC1001 family, the only difference between order codes is frequency, stability grade, and temperature range. A pin-compatible alternative at the same 28.6363 MHz would be the commercial-temperature (0°C to 70°C) variant — but the AEC-Q100 qualification is unique to this suffix. No second-source MEMS oscillator from another manufacturer shares the exact 4-VDFN pinout and electrical characteristics; a cross-qualification would require board-level validation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI1-028.6363T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI1-028.6363T when reusing this data.
