The DSC1001AI2-016.3840T: AEC-Q100 qualification means this part has passed the automotive-grade stress tests — temperature cycling, ESD, latch-up — required for under-hood and cabin electronics. The MEMS resonator replaces a quartz crystal, giving better shock and vibration immunity in the same 7.0 mm × 5.0 mm 4-SMD footprint.
Supply voltage and power-down standby
Operates from a single 1.8V to 3.3V supply, covering the common digital rails without a separate regulator. Maximum active current is 6.3 mA; the standby (power-down) function drops consumption to 15 µA max when the enable pin is pulled low — useful for sleep-mode wake-up in battery-backed or ignition-off automotive modules.
The DSC1001 series is an ongoing production line from Microchip; no pin-compatible replacement or second-source is required for current designs.
