Operates from a single 1.8 V to 3.3 V supply rail, so the same BOM line can serve a 1.8 V MCU core clock and a 3.3 V peripheral bus without a level translator. Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint that routes easily on two-layer automotive PCBs.
When the standby (power-down) function is enabled, the maximum supply current drops to 15 µA. This allows the oscillator to be disabled during system sleep without a separate power switch.
