PI3SSD1914 is designed to work in ONFI applications for advanced SSD SKUs. The purpose of the PI3SSD1914 is to effectively demultiplex ONFI-4 NAND commands and write data to one of the NAND ports as shown in Figure 1. The device also multiplexes the ONFI-4 NAND bus on a particular ONFI-4 NAND port to allow a selected target NAND bus to be routed to the host controller for data reads as
shown in Figure 2. Each PI3SSD1914 mux/demux, four ONFI-4-compliant NAND ports with typical 12ns switching time and maximum
500ps propagation delay. The core of the PI3SSD1914 operates at a supply voltage of 2.5V to 3.6V while the I/O interface circuits operate with an independent supply voltage from 1.2V to 1.8V. The supply voltage can be further reduced to 2.375V (min) for 1.2V VDDIO applications.
