Product details

What the standby current means on your bench

When the Standby (Power Down) pin is asserted, the oscillator draws 95 µA max — low enough that a coin cell can keep the clock tree alive through a sleep cycle without draining the main battery.

Industrial temp range and the 6-VDFN footprint

The 6-VDFN package measures 3.20 mm x 2.50 mm with a 0.90 mm seated height; the 0.50 mm pitch lands on a standard 6-pin DFN footprint with a centre pad that should be tied to the ground plane for thermal relief.

Supply-rail flexibility and output drive

The supply voltage spans 2.25 V to 3.6 V — one BOM line covers 2.5 V and 3.3 V logic rails without a separate regulator.

Frequently asked questions

What is the standby current for DSC1101CI2-020.0000T?

The maximum disable (standby) current is 95 µA when the Standby pin is asserted. Active-mode supply current is 35 mA max at 20 MHz.

Is DSC1101CI2-020.0000T RoHS compliant?

Yes, the DSC1101CI2-020.0000T is RoHS compliant per Microchip's standard material declaration for the DSC1101 series.

Does DSC1101CI2-020.0000T have a pin-compatible replacement?

Within the DSC1101 series, the base product number DSC1101 covers multiple frequency and stability options in the same 6-VDFN package — a different frequency variant is pin-compatible. For a drop-in replacement with the same footprint and function, check the DSC1101 family table for your target frequency.

What is the frequency stability of DSC1101CI2-020.0000T?

Frequency stability is ±25 ppm over the full operating temperature range and supply voltage variation.

Is DSC1101CI2-020.0000T pin compatible with DSC1001?

The DSC1101 and DSC1001 share the same 6-VDFN package and pinout — they are footprint-compatible. The DSC1101 adds a Standby (Power Down) function on pin 1, while the DSC1001 uses pin 1 for Output Enable. Verify the function your design expects on that pin before swapping.
