The MEMS resonator eliminates the quartz crystal's startup-time variability and shock sensitivity — useful if your board sees vibration or you need a consistent power-on clock within a few milliseconds. Frequency stability is ±50ppm over the 0°C~70°C commercial temperature range, which covers most indoor electronics, office equipment, and appliance PCBs. The 3mA max supply current is typical for a MEMS oscillator at this frequency; the real power story is the standby mode. ## Standby mode cuts supply to 1µA — why that matters The Standby (Power Down) function on pin 1 (typically) pulls the output to high-impedance and drops the supply current to 1µA max. For a battery-powered sensor node that spends most of its life asleep, this saves the 3mA continuous draw of a standard oscillator — the difference between a coin cell lasting weeks vs. months. The disable current is specified at 1µA maximum, not typical — so the worst-case sleep budget is known at design time. No external load-switch or MOSFET needed; the oscillator's own standby pin handles the power-down. It is suitable for new designs and production builds.","metaTitle":"DSC1030BC1-001.8432T MEMS XO 1.8432 MHz CMOS 3V ±50ppm","metaDescription":"Active Microchip MEMS oscillator, 1.8432 MHz, CMOS output, 3V supply, ±50ppm stability, 0-70°C, standby mode with 1µA disable current.","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":"DSC1030, PureSilicon™","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"1.8432 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"3V","Base Product Number":"DSC1030","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"0°C~70°C","Current - Supply (Max)":"3mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4b72b94fabfa3cb5855b7b290e3a940f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does DSC1030BC1-001.8432T have a standby mode?","answer":"Yes, the function is Standby (Power Down).
