This makes the part usable in battery-backed RTC or CAN wake-up circuits where the oscillator must sleep between bus events. The 1.8V to 3.3V supply range covers the common digital core and I/O voltages, so the same BOM line works across a 3.3V microcontroller and a 1.8V FPGA without a level translator on the clock input. ## Package and board-mounting note Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the DSC1001DI1-012.8000 fits the standard 2.5 x 2.0 mm MEMS oscillator footprint. The no-lead construction reduces parasitic inductance on the output compared to a leaded can, which helps maintain clean clock edges at 12.8 MHz.","metaTitle":"DSC1001DI1-012.8000 MEMS Oscillator 12.8 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1001DI1-012.8000 XO (Standard) MEMS oscillator, 12.8 MHz, CMOS output, AEC-Q100, -40°C to 85°C.

The DSC1001DI1-012.8000 is a MEMS-based XO (Standard) with a CMOS output, so it is a drop-in replacement for a 12.8 MHz quartz oscillator in the same 4-SMD, no-lead footprint. The MEMS construction offers better shock and vibration tolerance, and the ±50 ppm stability matches or exceeds many quartz oscillators. However, verify the supply voltage range (1.8V to 3.3V) and standby function match your circuit — a quartz oscillator may not have a power-down pin."},{"question":"Does the DSC1001DI1-012.8000 have a standby mode with low power?","answer":"Yes, the standby (power-down) function reduces the supply current to 15 µA max when disabled, compared to 6.3 mA max when active. This is useful for battery-backed or intermittently powered systems where the clock must sleep between wake events."},{"question":"What is the difference between the DSC1001DI1-012.8000 and the DSC1001DI1-012.0000?","answer":"The only difference is the output frequency: the DSC1001DI1-012.8000 is a 12.8 MHz oscillator, while the DSC1001DI1-012.0000 is a 12.0 MHz oscillator. Both share the same MEMS resonator, CMOS output, 1.8V to 3.3V supply, AEC-Q100 qualification, and 4-SMD no-lead package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DI1-012.8000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DI1-012.8000 when reusing this data.
