W29N02GV
9.1.5 READ ID (90h)
READ ID command is comprised of two modes determined by the input address, device (00h) or
ONFI (20h) identification information. To enter the READ ID mode, write 90h to the Command
Register followed by a 00h address cycle, then toggle #RE for 5 single byte cycles, W29N02GV. The
pre-programmed code includes the Manufacturer ID, Device ID, and Product-Specific Information
(see Table 9.1). If the READ ID command is followed by 20h address, the output code includes 4
single byte cycles of ONFI identifying information (See Table 9.2). The device remains in the READ
ID Mode until the next valid command is issued.
