This is the first gate in the timing chain for any automotive ECU that needs a clean reference clock without a crystal's startup delay. ## Standby function and current budget for battery-backed ECUs For a module that spends most of its life in sleep — a door controller or a telematics unit — this 400× current reduction preserves the battery reserve. ## Supply voltage flexibility and operating temperature range The oscillator operates from a 1.8V to 3.3V supply rail — a single part covers 1.8V, 2.5V, and 3.3V logic domains without a separate regulator. ## Package and board-level integration The 4-SMD, no-lead exposed pad package measures 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The MEMS resonator itself eliminates the need for external load capacitors, saving two passives per clock line.","metaTitle":"DSC1001AE2-004.0000 MEMS XO, 4 MHz, AEC-Q100, CMOS Output","metaDescription":"Microchip DSC1001AE2-004.0000 MEMS-based XO, 4 MHz, CMOS output, ±25 ppm stability, AEC-Q100 qualified.
