8. ENERGY SAVING MODE
8-1. Standby Mode
The device enters Standby mode whenever the RESET# and CE# pins are both held High except
in the embedded mode. While in this mode, WE# and OE# will be ignored, all Data Output pins will
be in a high impedance state, and the device will draw minimal (ICC3) current.
8-2. Automatic Sleep Mode
Automatic Sleep mode is able to minimize power consumption of flash device. The device
automatically enters this mode when the addresses and clock stays stable for tACC + 20 ns. The
automatic sleep mode will not be influenced by the CE#, WE#, and OE# control signals. Standard
address access timings are responsible for offering new data when addresses are changed.
Output data will be always available to the system and latched in sleep mode.
ICC6 in the Table 11. DC Characteristics indicates the current specifications for Automatic Sleep
mode.
