The standby function drops supply current to 15 µA max, enabling power gating in battery-backed or sleep-mode circuits without an external load switch. ## Supply range and power budget Operating from 1.8V to 3.3V, this oscillator can be powered directly from a 1.8V core rail or a 3.3V I/O rail, eliminating a dedicated regulator for the clock source. Maximum supply current is 6.3 mA during active operation — lower than many quartz-based oscillators at the same frequency, which helps keep the thermal budget tight in dense PCB layouts. ## Package and footprint compatibility Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the DSC1001CI1-012.2880 uses the same footprint as standard quartz oscillators, so it can be a drop-in replacement without a board layout change.","metaTitle":"DSC1001CI1-012.2880 MEMS Oscillator 12.288 MHz AEC-Q100","metaDescription":"Microchip DSC1001CI1-012.2880 XO, 12.288 MHz, CMOS output, ±50 ppm stability, AEC-Q100 qualified, 1.8-3.3V supply, 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":"Tube","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"12.288 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1001CI1-012.2880 AEC-Q100 qualified?","answer":"Yes, the DSC1001CI1-012.2880 is AEC-Q100 qualified, which means it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. This qualifies it for use in under-hood and cabin electronics where the ambient temperature can reach 85°C."},{"question":"Can DSC1001CI1-012.2880 replace a standard quartz oscillator?","answer":"Yes, in most cases. The DSC1001CI1-012.2880 uses a MEMS resonator instead of quartz, but it has the same 4-SMD, No Lead footprint and outputs a standard CMOS signal. The ±50 ppm stability is comparable to many quartz oscillators, and the wide supply range covers common voltages. The main difference is the standby pin — if your existing quartz oscillator does not have a standby function, you may need to leave the pin unconnected or tie it to Vdd."},{"question":"What is the function of the standby pin on DSC1001CI1-012.2880?","answer":"The standby (Power Down) function disables the oscillator output and reduces current consumption to 15 µA max. When the standby pin is asserted, the output goes into a high-impedance state, and the internal MEMS resonator stops oscillating. This is useful for battery-powered devices that need to save power during sleep modes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI1-012.2880","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI1-012.2880 when reusing this data.
