MEMS XO at 8 MHz – industrial temp, AEC-Q100 qualified
The DSC6001CI1A-008.0000T is a MEMS-based XO (Standard) from Microchip's DSC60XX series, delivering a fixed 8 MHz CMOS output with ±50ppm frequency stability across -40°C to +85°C. AEC-Q100 rated, this oscillator is designed for automotive-grade applications — engine bay, cabin, or chassis domains where temperature swings and vibration are routine. Supply voltage spans 1.71V to 3.63V, covering both 1.8V and 3.3V logic rails without a separate regulator. Typical current draw is 1.3 mA max, keeping the thermal footprint low in a 3.2×2.5 mm 4-SMD package.
Obsolete – sourcing reality for the BOM line
New designs should not target this order code. No official pin-compatible successor is listed by Microchip for this exact frequency and package.
Standby function and MEMS reliability
A Standby (Power Down) pin lets the oscillator shut down to near-zero quiescent current — useful in battery-backed or ignition-controlled modules where the clock only runs when the system is awake.
