Product details

MEMS oscillator for legacy automotive and industrial clocking

The DSC6001HE1A-018.4320 is a MEMS-based XO (Standard) oscillator from Microchip's DSC60XX series, delivering a fixed 18.432 MHz CMOS output with a standby power-down function. It operates from a 1.71V to 3.63V supply, drawing 1.3 mA typical, and is qualified to AEC-Q100 — suited for automotive cabin or under-hood modules that require a stable clock source across temperature. The 4-SMD no-lead package (1.6 mm x 1.2 mm footprint) is a common MEMS oscillator land pattern, compatible with standard reflow profiles for surface-mount assembly.

Obsolete status and sourcing path

A functional replacement would require a MEMS oscillator in the same 4-SMD package with matching 18.432 MHz frequency, CMOS output, and 1.71V–3.63V supply range — but the standby function and AEC-Q100 rating must be verified per the new part's datasheet.

Supply voltage and temperature compatibility

The 1.71V to 3.63V supply range directly covers 3.3V and 2.5V rails — no external level translation needed for the oscillator power pin.

Frequently asked questions

Is the DSC6001HE1A-018.4320 compatible with a 3.3V supply?

Yes. The supply voltage range is 1.71V to 3.63V, so a 3.3V rail is within spec.

What is the difference between a MEMS oscillator and a crystal oscillator?

A MEMS oscillator uses a micro-electromechanical resonator instead of a quartz crystal. The DSC6001HE1A-018.4320's MEMS base resonator provides inherent shock and vibration tolerance compared to a quartz crystal, and the CMOS output is a square wave ready for digital logic without external load capacitors.

Are MEMS oscillators suitable for automotive applications?

This specific part carries an AEC-Q100 rating, meaning it has passed automotive-grade qualification for reliability and temperature stress. It is suitable for legacy automotive designs that require a MEMS clock source.
