MEMS XO with AEC-Q100 and Wide Voltage Range
The DSC6001CI2A-000.0000 is a MEMS-based XO (Standard) from Microchip's DSC60XX series, delivering CMOS output from 1 MHz to 80 MHz with a total frequency stability of ±25 ppm. Its 1.71V to 3.63V supply span lets it run on 1.8V, 2.5V, or 3.3V rails without a separate regulator — a single BOM line covers multiple logic families. The MEMS resonator inherently resists shock better than quartz, which matters for engine-bay or chassis-mounted modules.
Lifecycle Reality: Obsolete, Sourced via Surplus
The blank-programmable nature means stock may be unprogrammed — confirm the frequency and configuration before committing to a lot. Because the part is obsolete, date-code consistency and traceability become the primary counterfeit screen. A lot with mixed date codes from different Microchip manufacturing weeks, or a laser etch that doesn't match Microchip's known font for that period, flags potential re-marked stock. We verify provenance through the authorized chain records and physical decap inspection when needed.
Supply and Power Budget for Battery-Powered Designs
For a battery-operated sensor node that sleeps most of the time, the disable current is low enough to treat as negligible in the sleep-state budget — the oscillator's contribution to lifetime is dominated by the active duty cycle. The 4-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.89 mm.
