Notes for software product identification:
(1) Data format: DQ7
DQ0 (Hex); address format: A14A0 (Hex).
(2) A1
A16 = VIL; manufacture code is read for A0 = VIL; device code is read for A0 = VIH.
(3) The device does not remain in identification mode if power down.
(4) The device returns to standard operation mode.
(5) This product supports both the JEDEC standard 3 byte command code sequence and original 6 byte command code
sequence. For new designs, Winbond recommends that the 3 byte command code sequence be used.
