Its MEMS resonator delivers faster startup and better shock/vibration tolerance than quartz, making it a fit for engine-control modules, ADAS cameras, and outdoor telecom nodes where quartz would drift or crack. ## Supply voltage agility and standby power Runs from 1.8V to 3.3V without a separate regulator — one oscillator covers the common logic rails in a mixed-voltage design. Standby (Power Down) function drops supply current to 15 µA max, letting the oscillator sleep between bus transactions and save power in battery-backed or always-on modules. This is a current-production part suitable for new designs and BOM replenishment. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1001BI1-040.0000 MEMS Oscillator 40 MHz CMOS AEC-Q100","metaDescription":"DSC1001BI1-040.0000 Microchip Technology MEMS XO, 40 MHz, CMOS output, AEC-Q100, -40°C to 85°C, 1.8V-3.3V, 4-SMD.
