Active production, automotive-qualified MEMS oscillator
The DSC1001CI5-027.0000: AEC-Q100 qualification (Grade 2, -40°C to +85°C) means this part is characterized for automotive cabin and body-electronics applications — under-hood ambient is covered with margin.
Supply voltage range and frequency stability
Operates from 1.7 V to 3.6 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without an external LDO — a single supply rail simplifies the power tree.
Active supply current is 8 mA max at 27 MHz, well within the drive capability of a small LDO or a GPIO-driven supply.
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the small footprint suits space-constrained PCBs in automotive ECUs or portable instrumentation. Surface-mount package; the 4-pin VDFN uses a standard reflow profile and does not require via-in-pad for thermal management.
