Deep Power Down (B9h)

Executing the Deep Power Down instruction is the best way to put the device in the lowest power consumption. The

Deep Power Down instruction reduces the standby current (from I

CC1 to ICC2, as specified in Table 8-7, AC Electrical

Characteristics

). The instruction is entered by driving the CS pin low with following the instruction code “B9h”. Refer to

Figure 7-37 and Figure 7-38 below.

The CS pin must go high exactly at the byte boundary (the latest eighth bit of instruction code been latched-in);

otherwise, the Deep Power Down instruction is not executed. After CS goes high, it requires a delay of t

DP and the Deep

Power Down mode is entered. While in the Deep Power Down state, the ‘Release Deep Power Down / Device ID’ (ABh)

instruction, which restores the device to normal operation, will be recognized. All other instructions are ignored, including

the ‘Read Status Register’ (05h) instruction, which is always available during normal operation.
