Figure 1. Connections for a 1x32 LPDDR4/4x Interface
Nibble utilization for 1x32 interface using one x32 component in the flipped configuration is shown in the following figure. This pinout provides the maximum interface performance compared to the 1x32 pin efficient version. DQ indicates data nibbles, AC indicates Address/Command/Control nibbles, sys_clk indicates a nibble comprising the System Clock pair, RESET_n, and ALERT_n signals.
Important: The nibble
utilization figure is based on the fixed pinout output by Vivado for this configuration.
