Release from deep power-down (RDP)

Once the device has entered the deep power-down mode, all instructions are ignored

except the release from deep power-down (RDP) instruction. Executing this instruction

takes the device out of the deep power-down mode.

The release from deep power-down (RDP) instruction is entered by driving Chip Select (S)

Low, followed by the instruction code on serial data input (D). Chip Select (S) must be driven

Low for the entire duration of the sequence.

The instruction sequence is shown in Figure 23.

The release from deep power-down (RDP) instruction is terminated by driving Chip Select

(S) High. Sending additional clock cycles on Serial Clock (C), while Chip Select (S) is driven

Low, cause the instruction to be rejected, and not executed.

After Chip Select (S) has been driven High, followed by a delay, tRDP, the device is put in the

standby mode. Chip Select (S) must remain High at least until this period is over. The device

waits to be selected, so that it can receive, decode and execute instructions.

Any release from deep power-down (RDP) instruction, while an erase, program or write

cycle is in progress, is rejected without having any effects on the cycle that is in progress.
