The MEMS resonator gives it an edge over quartz in shock and vibration tolerance — the silicon die doesn't crack the way a quartz blank does when a board takes a hit. The 6-VDFN exposed pad package (7.00mm x 5.00mm, 0.90mm seated height) needs a thermal via pattern under the pad to pull heat out; the datasheet layout recommendation is worth following for the full temp range. Max supply current is 35mA when enabled, dropping to 22mA in the disabled state. The 22mA disabled current is higher than some competitors' parts; if your design sleeps the oscillator for long periods, a load switch on the supply rail might save more power.","metaTitle":"DSC1121AM1-032.7680 MEMS Oscillator","metaDescription":"DSC1121AM1-032.7680 MEMS oscillator from Microchip: 32.768 MHz, CMOS output, -55°C to 125°C, 2.25V-3.6V supply, 6-VDFN package.","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":"DSC1121","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"32.768 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"-","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-55°C~125°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"±50ppm","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can the DSC1121AM1-032.7680 replace a standard quartz oscillator?","answer":"Yes, it is a drop-in replacement for a 32.768 MHz quartz oscillator in the same 6-VDFN footprint, with the same CMOS output and supply voltage range. The MEMS base resonator is more resistant to shock and vibration than quartz, and it starts up faster — typically under 5 ms vs 10-20 ms for quartz. The Enable/Disable function is a bonus that quartz parts may not offer."},{"question":"Is the DSC1121AM1-032.7680 RoHS and lead-free compliant?","answer":"The DSC1121AM1-032.7680 is listed as RoHS compliant per Microchip's documentation.
