DEVICE OPERATION (CONTINUED)
RDID COMMAND (READ PRODUCT
IDENTIFICATION)/
OPERATION
The Release from Power-down or High performance
Mode / Device ID instruction is a multi-purpose
instruction. The Read Product Identification (RDID)
instruction is for reading out the old style of 8-bit
Electronic Signature, whose values are shown as table
of ID Definitions. This is not same as RDID or JEDEC
ID instruction. It’s not recommended to use for new
design. For new design, please use RDID or JEDEC ID
instruction.
The RDES instruction code is followed by three dummy
bytes, each bit being latched-in on SI during the rising
edge of SCK. Then the Device ID is shifted out on SO
with the MSB first, each bit been shifted out during the
falling edge of SCK. The RDES instruction is ended by
CE# goes high. The Device ID outputs repeatedly if
continuously send the additional clock cycles on SCK
while CE# is at low.
To release the device from the power-down state Mode,
the instruction is issued by driving the CE# pin low,

Release from power-down will take the time duration of

remain high during the t
Release from Power-down / RDID instruction is issued
while an Erase, Program or Write cycle is in process
(when BUSY equals 1) the instruction is ignored and
will not have any effects on the current cycle
