AEC-Q100 qualification means this part has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) required for production vehicle programs — not just a datasheet claim, but a documented qualification. ## Standby power-down and supply flexibility A dedicated Standby (Power Down) function drops the supply current to 15 µA max when the enable pin is pulled low — useful for battery-backed modules or systems that cycle power between active sessions to save energy. The wide supply range of 1.8V to 3.3V lets this oscillator run directly from a 1.8V core rail or a 3.3V I/O rail without an extra regulator, simplifying the power tree on mixed-voltage designs. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1001BL2-040.0000T – Microchip MEMS XO, 40 MHz, CMOS","metaDescription":"DSC1001BL2-040.0000T: Microchip MEMS XO, 40 MHz, CMOS output, ±25 ppm stability, -40°C to 105°C, AEC-Q100 qualified.
