Product details

MEMS clock for tight spaces

It draws 3 mA typical during operation and drops to 1 µA in standby (power-down mode), so a battery-backed real-time clock section can gate the oscillator off when the main processor sleeps.

Microchip lists the DSC1033CI1-030.0000T as obsolete. No official successor is named in the product records. The 4-SMD, no-lead package (3.20 mm x 2.50 mm) is a common MEMS oscillator footprint shared by many Microchip and SiTime parts, so a pin-compatible replacement may exist within the same family — verify the function and supply voltage before swapping.

Frequently asked questions

What is the replacement for DSC1033CI1-030.0000T?

Microchip has not published an official direct replacement for this order code. A functionally similar MEMS oscillator in the same 4-SMD, 3.2 mm x 2.5 mm footprint with 3.3 V CMOS output and ±50 ppm stability may serve as a drop-in — verify the standby function and disable current before substituting.
