It communicates over a SPI bus with Quad I/O support, shifting four data bits per clock cycle. The part runs on a 2.7 V to 3.6 V supply and operates from -40°C to 85°C.
133 MHz clock and Quad I/O — what the speed rating means for your bus
The 133 MHz clock frequency is the maximum SPI clock the device guarantees across the full voltage and temperature range. With Quad I/O enabled, each clock edge transfers four bits.
