Product details

32.768 kHz MEMS XO for automotive timing

It delivers a CMOS output from a 1.71V to 3.63V supply, covering 1.8V, 2.5V, and 3.3V logic rails without a separate regulator.

MEMS resonator vs quartz: what AEC-Q100 means for the BOM

The MEMS base resonator replaces a quartz crystal — no aging drift, no shock sensitivity. A quartz XO at the same price point would require a separate qualification lot and may still fail the vibration profile.

Package and footprint for space-constrained boards

Housed in a 4-VFLGA package measuring 2.00mm x 1.60mm with a seated height of 0.89mm, this oscillator fits under a shield can or alongside a QFN MCU. Maximum supply current is 1.19 mA typical — low enough that a GPIO pin on the host MCU can supply the enable signal without a dedicated power switch.

Frequently asked questions

Is DSC6003MA3B-032K768 AEC-Q100 qualified?

Yes, it is rated AEC-Q100, meaning it is qualified for automotive temperature grades and reliability stress tests — suitable for under-hood, cabin, or chassis-domain timing.

What is the closest pin-compatible alternative to DSC6003MA3B-032K768?

No official pin-compatible alternative or cross-reference is listed by Microchip. The DSC60XX series shares the same package and pinout across frequencies, so a different frequency variant (e.g., DSC6003MA3B-032768) would be footprint-compatible but frequency-specific.
