Notes for software product identification/boot block lockout detection:
(1) Data Format: DQ7
DQ0 (Hex); Address Format: A14A0 (Hex)
(2) A1
A18 = VIL; manufacture code is read for A0 = VIL; device code is read for A0 = VIH.
(3) The device does not remain in identification and boot block (address 0002 Hex/3FFF2 Hex respond to first 16K/last 16K) lockout detection
mode
if power down.
(4), (5) If the output data is "FF Hex," the boot block programming lockout feature is activated; if the output data "FE Hex," the lockout feature is
inactivated and the block can be programmed.
(6) The device returns to standard operation mode.
(7) 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.
