Product details

66 MHz MEMS oscillator — AEC-Q100 for automotive timing

The DSC1001DI1-066.0000 is a 66 MHz XO (Standard) MEMS oscillator from Microchip's DSC1001 series, delivering a CMOS output in a 4-SMD no-lead package measuring 0.098" x 0.079" (2.50mm x 2.00mm).

Supply range and power budget for the board

Maximum draw is 7.2mA when enabled, dropping to 15µA in disable — the disable current matters for a sleep-mode ECU that keeps the oscillator powered but gated off between wake cycles.

Active lifecycle — sourced per RFQ

Product status is Active, meaning Microchip continues to manufacture and support this order code.

Frequently asked questions

Is DSC1001DI1-066.0000 a drop-in replacement for a failed quartz oscillator?

The DSC1001DI1-066.0000 is a MEMS-based XO, not a quartz resonator. It is a drop-in replacement for a standard 4-pin 2.50mm x 2.00mm oscillator footprint if the original was a 66 MHz CMOS-output XO with Enable/Disable. Confirm the supply voltage range (1.8V to 3.3V) and frequency stability (±50ppm) match the board's requirements before substitution.

What is the footprint and mounting detail for DSC1001DI1-066.0000?

The package is 4-SMD, No Lead, with dimensions 0.098" L x 0.079" W (2.50mm x 2.00mm) and a seated height of 0.035" (0.90mm). It is a surface-mount device; the four pads are on the bottom of the package. The datasheet provides the recommended land pattern and solder stencil aperture.

Does DSC1001DI1 have a datasheet with pinout and electrical characteristics?

Yes, the DSC1001 series datasheet from Microchip includes the pinout, DC/AC characteristics, timing diagrams, and application notes for the Enable/Disable function. The base product number is DSC1001, and the full datasheet is available from Microchip's website.
