Product details

Available through independent surplus distribution in lot-specific quantities.

32 MHz MEMS oscillator with industrial temperature range

This is a 32 MHz MEMS-based XO (Standard) with CMOS output, operating from a 3.3V supply rail. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, which is a practical advantage in motor-drive and automotive-adjacent applications.

Package and footprint for PCB layout

Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The no-lead land pattern requires a solder-paste stencil aperture matched to the pad dimensions in the datasheet — the small pads are sensitive to misalignment during reflow. The standby (power down) function on pin 1 pulls the output to high-impedance and drops supply current to 1 µA max, which is useful for battery-powered systems that need to gate the clock tree without an external load switch.

Frequently asked questions

Is DSC1033BI1-032.0000 obsolete?

Yes, Microchip Technology lists this part as Obsolete. It is no longer in production and is not recommended for new designs. Sourcing is through independent surplus channels; quantities are confirmed at RFQ.

What is the replacement for DSC1033BI1-032.0000?

No official replacement or pin-compatible successor is documented by Microchip for this order code. A functionally equivalent MEMS XO with the same 32 MHz frequency, 3.3V supply, CMOS output, and 4-SMD package would need to be evaluated against the BOM's stability and temperature requirements.
