The supply voltage spans 1.8V to 3.3V, so it can run off a 1.8V core rail or a 3.3V I/O rail without a separate regulator — handy when you're consolidating power domains on a tight board.
Active current is 8 mA max at 50 MHz, so the oscillator itself won't dominate the power budget in a typical MCU clock tree.
