MEMS oscillator at 80 MHz with automotive-grade qualification
The DSC6001CI1A-080.0000T is a MEMS-based XO (standard) from Microchip's DSC60XX series, delivering an 80 MHz CMOS output with ±50 ppm frequency stability across the full -40°C to +85°C industrial temperature range. It operates from a wide supply range of 1.71V to 3.63V, making it compatible with both 1.8V and 3.3V logic domains without an external level translator. The Enable/Disable function lets the system shut down the oscillator for power savings — useful in automotive modules that sleep between ignition cycles.
Microchip has marked the DSC6001CI1A-080.0000T as obsolete. Available through independent distribution on a quoted-to-order basis. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here. A board-level redesign with a current-generation MEMS oscillator from the DSC60XX family may be required.
AEC-Q100 qualification and package fit
Rated AEC-Q100, this oscillator is qualified for automotive stress and reliability — suitable for under-hood or cabin electronics where temperature cycling and vibration are concerns. Housed in a 4-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The 0.50 mm pitch and no-lead footprint require careful solder-paste stencil design to avoid bridging. Typical supply current is 1.3 mA max — the MEMS resonator draws less than a quartz crystal oscillator at the same frequency, which helps keep the thermal budget low in dense automotive PCBs.
