Available through independent surplus channels; quantities are lot-specific and confirmed at RFQ. ## 28.636 MHz MEMS oscillator with standby function A MEMS-based XO (Standard) delivering a 28.636 MHz CMOS output on a 1.8V supply rail. The standby (power-down) function drops supply current to 1 µA max when the enable pin is pulled low — useful for battery-powered equipment that clocks down between active cycles. Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm — a compact footprint that matches the common 2.5 x 2.0 mm MEMS oscillator land pattern. ## Frequency stability and current draw Frequency stability is ±50 ppm across the full temperature and voltage range — tight enough for UART baud-rate generation and most MCU clock trees without external trimming. Typical supply current is 3 mA during active oscillation, so the oscillator load on a 1.8V rail is negligible in a mixed-signal power budget.","metaTitle":"DSC1018DI1-028.6360T – Microchip MEMS XO, 28.636 MHz, CMOS","metaDescription":"DSC1018DI1-028.6360T is a Microchip MEMS XO (Standard) with 28.636 MHz CMOS output, 1.8V supply, ±50ppm stability, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1018","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"28.636 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"1.8V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"3mA (Typ)","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/0291cd7293e82768a7c2198660ff52d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for the DSC1018DI1-028.6360T?","answer":"Microchip has not published a direct pin-compatible replacement for this obsolete order code.
