Product details

AEC-Q100 qualified MEMS oscillator for automotive clocks

The DSC1003CI2-008.0000 is an 8 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1003 series, rated AEC-Q100.

Operates from 1.7 V to 3.6 V, covering both 1.8 V and 3.3 V logic rails directly. The CMOS output swings rail-to-rail and drives up to 8 mA max, enough to fan out to two or three MCU clock inputs without a buffer.

Standby power-down function

This is the feature that lets a battery-powered module shut down the oscillator between wake cycles while keeping the MEMS resonator ready for a fast restart.

Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm.

Listed as Active by Microchip Technology.

Frequently asked questions

Is the DSC1003CI2-008.0000 AEC-Q100 qualified?

Yes. The part carries an AEC-Q100 rating, which means it has passed the automotive-grade qualification tests including temperature cycling, ESD, and latch-up.

Can the DSC1003CI2-008.0000 replace a standard quartz crystal oscillator?

Yes, in most cases. The DSC1003CI2-008.0000 is a MEMS-based XO (Standard) that generates a CMOS clock output directly — no external load capacitors or inverter stage needed. It is a drop-in replacement for a quartz crystal oscillator module of the same frequency, output type, and package footprint, with the added benefits of better shock/vibration resistance and a standby power-down function.

What is the difference between the DSC1003CI2-008.0000 and the DSC1003DI2-008.0000?

The difference is in the package code. The 'CI2' suffix indicates a 4-VDFN package with a specific temperature range and stability grade; the 'DI2' variant uses a different package or temperature option within the same DSC1003 series. Both are 8 MHz MEMS oscillators with the same supply range and CMOS output. Confirm the exact package code and temperature range in the datasheet before substituting.

What is the difference between the DSC1003 and DSC1001 series?

The DSC1003 series includes a standby (power down) function, while the DSC1001 series does not. If your design requires the ability to shut down the oscillator to save power, the DSC1003 is the correct choice. Both series share the same MEMS resonator technology and package options.
