The DSC6003MI1A-000.0000T is officially obsolete per Microchip Technology's lifecycle status.
Automotive-grade MEMS oscillator with wide voltage range
This MEMS-based XO (Standard) outputs a CMOS clock from 1 MHz to 80 MHz, blank-programmable by the user. The supply voltage spans 1.71 V to 3.63 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator.
User-programmable – plan for programming step
The DSC6003MI1A-000.0000T ships as a blank device — the frequency must be programmed before use. Microchip provides a programming tool and software, but this adds a non-recurring step to your assembly flow. If you need a fixed-frequency part off the shelf, consider a pre-programmed variant in the DSC60XX family.
Compact 2.0 mm × 1.6 mm 4-SMD package
Housed in a 4-SMD no-lead package measuring 2.00 mm × 1.60 mm with a seated height of 0.89 mm. The small footprint suits space-constrained designs like automotive ECUs or portable instrumentation. Surface-mount assembly is standard; no special reflow profile beyond the usual lead-free process.
