(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. |
