Product details

Obsolete – last-time-buy window closed

Microchip has marked the DSC6003CE1A-012.2880T as Obsolete. Available through independent surplus channels in lot-specific quantities. No official successor or pin-compatible replacement listed by Microchip for this exact order code.

12.288 MHz MEMS oscillator with AEC-Q100 grade

MEMS-based XO (Standard) delivering a 12.288 MHz CMOS output. The ±50 ppm frequency stability keeps the clock edge within tight timing margins over the -20°C to +70°C commercial temperature range. AEC-Q100 qualified – this oscillator passed the automotive-grade stress and reliability tests, suitable for under-hood or chassis-domain electronics where vibration and thermal cycling are present. Supply voltage spans 1.71V to 3.63V, covering both 1.8V and 3.3V rails without an external level shifter. The Enable/Disable function allows the output to be tri-stated for power savings or test isolation.

4-VDFN package – board layout note

Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The small footprint suits space-constrained designs, but the no-lead construction requires a solder-paste stencil aperture matched to the pad geometry for consistent fillet formation. Surface-mount only – the 4-VDFN does not support through-hole rework.

Frequently asked questions

What is the replacement for the DSC6003CE1A-012.2880T?

Microchip has not listed an official successor or pin-compatible replacement for this order code. For new designs, consider a current-production MEMS oscillator from the DSC60XX family with the same 12.288 MHz frequency, CMOS output, and AEC-Q100 grade – verify pinout and package compatibility against the original BOM.

Is the DSC6003CE1A-012.2880T compatible with a 3.3V supply?

Yes. The supply voltage range is 1.71V to 3.63V, so both 1.8V and 3.3V rails are within spec. The CMOS output swings rail-to-rail, so no level translation is needed when driving a 3.3V logic input.
