DEVICE OPERATION (CONTINUED)
RDMDID COMMAND (READ DEVICE MANUFACTURER AND DEVICE ID)
OPERATION
The Read Product Identification (RDID) instruction
allows the user to read the manufacturer and product
ID of the devices. Refer to Table 12 Product
Identification for pFLASH™ manufacturer ID and
device ID. The RDID instruction code is followed by
two dummy bytes and one byte address (A7~A0), each
bit being latched-in on SI during the rising edge of SCK.
If one byte address is initially set to A0 = 0, then the
first manufacturer ID (9Dh) is shifted out on SO with

the MSB first, the device ID1 and the second
manufacturer ID (7Fh), each bit been shifted out during
the falling edge of SCK. If one byte address is initially
set to A0 = 1, then device ID1 will be read first, then
followed by the first manufacture ID (9Dh) and then
second manufacture ID (7Fh). The manufacture and
device ID can be read continuously, alternating from
one to the others. The instruction is completed by
driving CE# high.
