AEC-Q100 qualification means this part has passed the automotive-grade stress tests: temperature cycling, ESD, latch-up, and extended high-temperature operating life. It is suited for under-hood and cabin ECUs where a quartz oscillator would need a separate qualification run. Listed as Active by Microchip. The part is available for both new designs and ongoing production runs — no need to stockpile or qualify a second source. ## Standby function and disable current The standby (power-down) function drops the supply current to 15 µA max when the enable pin is pulled low. Normal operation draws 7.2 mA max. For battery-backed or ignition-switched modules, the standby current is low enough to avoid draining the keep-alive supply. 4-SMD no-lead package, 3.20 mm x 2.50 mm body, seated height 0.90 mm max. Surface-mount, tape-and-reel delivery. The small footprint and low profile fit dense ECU layouts where board space is tight.","metaTitle":"DSC1001CI2-028.3220B MEMS XO – 28.322 MHz, AEC-Q100, Active","metaDescription":"Microchip DSC1001CI2-028.3220B: 28.322 MHz MEMS XO, CMOS output, 1.8V–3.3V supply, AEC-Q100 qualified, -40°C to 85°C.
