Figure 1. Connections for a Pin Efficient 1x32 LPDDR4/4x Interface

Nibble utilization for pin efficient 1x32 interface using one x32 component in the non-flipped configuration is shown in the following figure. For maximum interface performance use the 1x32 pinout described in the Figure titled "Nibble utilization for 1x32 component interface (Non-Flipped)". 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. Refer to Clocking for System Clock details.

Important: The nibble utilization figure is based on the fixed pinout output by Vivado for this configuration.
Note: For LPDDR4/LPDDR4x pin efficient configurations, different IO standards for reset_n other than those recommended by Vivado are allowed, and the warning reported by Vivado can be ignored.
