The 1.8V supply rail and typical 3 mA active current (1 µA in standby) suit low-power applications where a quartz crystal would draw more board area and current.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm.
Yes, Microchip lists this part as Obsolete. There is no official pin-compatible replacement from Microchip. Sourcing is through independent surplus channels; quantities are lot-specific and confirmed at RFQ.
This is a standard stability grade for general-purpose clocking; tighter stability (e.g., ±25 ppm) would require a different oscillator family.
As an obsolete part, it is not stocked in volume. We source it through independent surplus channels — submit an RFQ with your target quantity and we confirm availability and pricing per lot.
