The DSC6001CI1A-PROGRAMMABLE is a MEMS-based XO from Microchip's DSC60XX series, delivering a CMOS output clock from 1 MHz to 80 MHz with a total frequency stability of ±50 ppm across the full -40°C to +85°C industrial temperature range. Supply voltage spans 1.71V to 3.63V, covering 1.8V, 2.5V, and 3.3V logic rails without an external regulator, and typical current draw is just 1.3 mA — low enough for always-on modules in a vehicle.
Obsolete status and sourcing path
For existing BOM lines, this part is available through independent surplus channels. A functional replacement will require evaluating current MEMS XO families with similar supply and package, but a board spin may be needed.
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.89 mm — a standard 3.2x2.5 mm MEMS oscillator footprint that drops onto existing pads for many 4-pin clock devices.
