... See the Command Execution section for more detail. DEEP POWER-DOWN MODE To allow for maximum power conservation, the MT28F800B3 and MT28F008B3 feature a very low cur- rent, deep power-down mode. To enter this mode, the RP# pin is taken to V ±0.2V. In this mode, the current SS draw is a maximum of 8µ ...

... WE# must be HIGH, and OE# and CE# must be LOW. However, ID register data is output only on DQ0– DQ7, regardless of the condition of BYTE# on the MT28F800B3 used to decode between the two bytes of the device ID register; all other address inputs are “Don’t Care.” When A0 is LOW, the manufacturer com- patibility ID is output, and when A0 is HIGH, the device ID is output.
