The die is silicon, not quartz, so the frequency vs temperature curve is flat across the industrial band without the turnover-point sensitivity of an AT-cut crystal. ## Supply voltage and standby — one rail, one pin Supply range 1.8 V to 3.3 V covers the three common logic rails — no separate regulator for 1.8 V or 2.5 V domains. The same part serves a 3.3 V CAN transceiver clock and a 1.8 V MCU core clock on the same BOM line. For a battery-backed ECU that sleeps 99 % of the time, the 15 µA leakage is below the sleep-mode budget of a typical SBC. ## Active lifecycle — no redesign clock ticking The part can be designed in today without a forced obsolescence migration mid-production. The base product number DSC1001 covers a family of pin-compatible MEMS oscillators; if a different frequency is needed later, the same footprint and supply rails apply.","metaTitle":"DSC1001CI1-025.0000T — Microchip MEMS XO, 25 MHz, CMOS","metaDescription":"Active-production MEMS oscillator from Microchip, 25 MHz CMOS output, AEC-Q100 qualified, 1.8-3.3 V supply, standby function.

In standby the output goes high-impedance, so the downstream clock input sees a tri-state rather than a stuck-low or stuck-high level."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI1-025.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI1-025.0000T when reusing this data.
