The 4-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — it is a standard 3.2 x 2.5 mm footprint that matches many quartz oscillators, so a board designed for a quartz XO in that size can accept the DSC1001 without a layout change. The surface-mount pads are on the bottom; no through-holes are needed.","metaTitle":"DSC1001CI1-032.7680 – Microchip MEMS XO, 32.768 MHz, CMOS","metaDescription":"Active Microchip DSC1001CI1-032.7680 XO (Standard) with MEMS resonator, 32.768 MHz CMOS output, ±50 ppm stability, -40°C to +85°C, AEC-Q100.

The supply voltage range is 1.8 V to 3.3 V, so it operates directly from a 1.8 V rail without an external regulator. The CMOS output swings rail-to-rail at any voltage in that range."},{"question":"What is the standby power consumption of the DSC1001CI1-032.7680?","answer":"When the standby (power-down) function is asserted, the supply current drops to 15 µA maximum. In normal operation the maximum supply current is 7.2 mA."},{"question":"Can the DSC1001CI1-032.7680 replace a failed quartz oscillator in an existing design?","answer":"If the original oscillator is a 32.768 MHz CMOS-output XO in a 3.2 mm x 2.5 mm 4-pin SMD package with a 1.8 V–3.3 V supply, the DSC1001CI1-032.7680 is a direct form-fit-function replacement. The MEMS resonator has different jitter characteristics than quartz, but the ±50 ppm stability and CMOS output are electrically compatible. Confirm the original part's frequency stability and temperature range match before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI1-032.7680","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI1-032.7680 when reusing this data.
