Supply voltage spans 1.8V to 3.3V, so the same oscillator can feed a 1.8V FPGA bank and a 3.3V MCU without a second PLL or level translator. The wide range also simplifies inventory—one line item covers multiple rail voltages on the BOM.
Standby mode and power budget for battery systems
This lets a battery-powered ECU or sensor node shut down the main clock without a discrete load switch, saving board space and keeping the sleep current under the microcontroller's own deep-sleep draw.
