The MEMS resonator replaces a quartz crystal, giving better shock and vibration immunity — useful for engine-bay or factory-floor environments where a quartz can micro-crack. The AEC-Q100 qualification means it has passed automotive-grade reliability stress tests including temperature cycling and ESD — suitable for under-hood or chassis-domain modules that see thermal cycling and vibration. ## Standby power-down and supply flexibility A Standby (Power Down) function drops the supply current to 15 µA max when the enable pin is pulled low — handy for battery-backed RTC or telemetry systems that sleep between transmissions. Active current is 6.3 mA max at 1.544 MHz, so the oscillator itself is not the dominant power draw in most designs. Supply voltage range is 1.8V to 3.3V, covering common logic rails without an external regulator. The 4-SMD, No Lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that reflows easily and fits tight PCB stacks.","metaTitle":"DSC1001BI2-001.5440T MEMS XO – 1.544 MHz, AEC-Q100, Active","metaDescription":"Microchip DSC1001BI2-001.5440T: MEMS-based XO, 1.544 MHz CMOS output, ±25 ppm stability, -40°C to 85°C, AEC-Q100 qualified.
