Product details

The DSC1001CE1-027.0000T is a 27 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering CMOS output across a 1.8V to 3.3V supply range. Rated for -20°C to 70°C with ±50 ppm frequency stability, it draws 7.2 mA max from the supply and drops to 15 µA in standby (power-down) mode.

No successor or replacement has been issued; the base product number DSC1001 remains the current series for this frequency and package variant.

4-SMD no-lead footprint and supply flexibility

Housed in a 3.20 mm x 2.50 mm 4-SMD no-lead package (0.90 mm seated height), the part is a drop-in fit for standard XO footprints with a 0.50 mm pitch — no via-in-pad required. The 1.8V–3.3V wide supply range lets it share a rail with the core or I/O voltage of a common MCU or SoC without an extra regulator.

Frequently asked questions

What is the closest alternative to the DSC1001CE1-027.0000T?

Within the DSC1001 series, other frequency variants share the same 4-SMD package, supply range, and AEC-Q100 rating. For a pin-compatible 27 MHz XO with a different stability grade or temperature range, check the DSC1001 family ordering options — the base product number DSC1001 covers the same footprint.

What does the AEC-Q100 rating mean for this oscillator?

AEC-Q100 qualification means the part has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. It is specified for -20°C to 70°C ambient, which covers cabin and most under-hood locations in passenger vehicles.
