5.72 Enter Power-Down (PD)

The Enter Power-Down (PD) instruction places the device into a low-power operating state referred to as Power-Down mode.

While the device is in Power-Down mode, all instructions are ignored except the Release Power-Down instruction. To enter Power-Down mode, the host drives CE# low, issues the PD command (B9H) in SPI or QPI mode, and then drives CE# high. After CE# transitions high, a delay of T_PD is required before the standby current (I_SB) decreases to the power-down current (I_PD).

If the device is actively performing an internal erase or program operation, the Power-Down instruction is ignored. Refer to Figure 5-62 and Figure 5-63 for the command sequences.
