Listed as Active by Microchip — no EOL notice, no last-time-buy window. The part is in ongoing production and can be ordered against a BOM quantity without obsolescence risk.
Operates from 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without a separate regulator.
Yes, the DSC1121AI1-125.0000 carries AEC-Q100 qualification, meaning it is tested to automotive-grade reliability standards for temperature, humidity, and operating life.
Yes, the DSC1121AI1-125.0000 includes an Enable/Disable function. When disabled, the supply current drops to 22 mA max, allowing the system to gate the clock for power savings.
