When the Standby (Power Down) pin is asserted, the oscillator draws 15 µA max — low enough to leave on a battery-backed rail without draining the cell. The supply voltage range is 1.8V to 3.3V, so it can run directly from a 1.8V MCU rail or a 3.3V system bus without an extra regulator.
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts.
Yes, it carries AEC-Q100 ratings, which qualifies it for automotive applications requiring the temperature range, reliability stress, and PPAP documentation that standard commercial oscillators lack.
When the Standby (Power Down) function is active, the maximum supply current is 15 µA. This allows the oscillator to be left connected to a battery or always-on supply without significant drain.
