Software Protection (SP)/
Deep Powerdown (DP)
The DP instruction is included in the device
in order to be compatible with other SPI
Flash devices, and is identical to the SP
instruction.
The SA25F020's low standby current of
1 μA is the same in both DP and Standby
modes. It is recommended that the
standard Standby mode be used for the
lowest power current draw, as well as an
extra SP mechanism while the device is
not in active use. This is due to the fact
that while in this mode, the device ignores
all Write, Program and Erase instructions.
The SP instruction is entered by driving
CSb low, followed by the instruction code
on the SI pin. CSb must be driven low for
the entire duration of the sequence. The
instruction sequence is shown in Figure 20.
CSb must be driven high after the eighth
bit of the instruction code has been latched
in; otherwise, the SP instruction is not
executed. As soon as CSb is driven high, it
requires a delay of t
DP
before SP mode is
entered.
Once the device has entered SP mode, all
instructions are ignored except the Release
from Software Protect and Read Electronic
Signature
(RES)
release the device from this mode. RES
instructions also enable the Electronic
Signature to be read on the SO pin.
