AEC-Q100 qualified, so it fits automotive BOMs without a separate qualification step — cabin ECUs, infotainment head units, and sensor fusion modules are the typical deployment.
Maximum supply current is 6.3 mA at 4 MHz — low enough to share a 3.3V rail with the MCU core without a dedicated LDO.
4-SMD no-lead package, 3.20 mm x 2.50 mm footprint, 0.90 mm seated height.
Yes — rated AEC-Q100. This qualifies it for automotive applications without additional PPAP paperwork from the buyer's side.
Any DSC1001 variant with the same 4-SMD no-lead package and CMOS output is footprint-compatible — the difference is frequency and stability grade. The base product number DSC1001 covers the series; confirm the specific frequency and stability before substituting.
