Product details

For an engine-bay ECU or outdoor telecom node that sees 70°C on a hot day, the MEMS resonator holds ±50 ppm stability without the frequency jump a quartz crystal can exhibit near its activity dip.

Supply flexibility and standby current

The wide supply range of 1.8V to 3.3V lets the same oscillator serve 1.8V-core and 3.3V-I/O domains without a separate level translator.

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

The DSC1001 series is Microchip's mainstream MEMS oscillator family; no official successor has been announced. The AEC-Q100 qualification and MEMS construction mean this part is a drop-in replacement for quartz XOs in the same 7.0 x 5.0 mm 4-pin footprint, provided the supply voltage and frequency match.

Frequently asked questions

What is the standby current consumption of DSC1001AE1-018.0000?

When the Standby (Power Down) function is enabled, the supply current drops to 15 µA maximum. Active draw is 6.3 mA max.

Is DSC1001AE1-018.0000 compatible with standard 4-pin oscillator footprints?

Yes. The 4-SMD, No Lead Exposed Pad package uses the standard 7.0 mm x 5.0 mm footprint with pin 1 standby, pin 2 ground, pin 3 output, pin 4 supply. It is a direct mechanical and electrical replacement for quartz oscillators of the same size and pinout.
