Supply voltage spans 1.8 V to 3.3 V, making it a single-clock-source fit for mixed-voltage domains — a 3.3 V MCU and a 1.8 V FPGA can share the same oscillator without a level translator on the clock line. ## AEC-Q100 qualification and commercial temperature grade That means it is suited for cabin electronics (infotainment, cluster, telematics) where the ambient stays above freezing, not for under-hood or exterior modules that see -40°C cold cranks. For a 12.8 MHz reference driving a CAN FD controller or 100BASE-T1 PHY inside the cabin, the ±10 ppm stability keeps the bit-time error below 0.01 UI — well within the 1.5% tolerance required by the CAN bus specification. The MEMS construction also means no frequency drift from board flex or thermal shock during reflow, a common failure mode for quartz oscillators in automotive assemblies. Housed in a 4-SMD, no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the same footprint as a standard 7x5 mm quartz oscillator, so it is a drop-in replacement for existing board layouts designed for that form factor. No special handling beyond standard MSL precautions; MEMS oscillators are generally moisture-insensitive, but the reel label carries the MSL level for confirmation.","metaTitle":"DSC1001AC5-012.8000T MEMS Oscillator – 12.8 MHz, CMOS","metaDescription":"Microchip DSC1001AC5-012.8000T: 12.8 MHz XO, CMOS output, ±10 ppm stability, AEC-Q100 rated, 0°C–70°C, 4-SMD package.
