AC CHARACTERISTICS

Notes:

1. Status reads in figure are shown as asynchronous.

2. VA = Valid Address. Two read cycles are required to determine status. When the Embedded Algorithm operation is complete,

and Data# Polling will output true data.

3. While in Asynchronous mode, RDY will be low while the device is in embedded erase or programming mode.

Data# Polling Timings (During Embedded Algorithm)

Notes:

1. Status reads in figure are shown as asynchronous.

2. VA = Valid Address. Two read cycles are required to determine status. When the Embedded Algorithm operation is complete,

the toggle bits will stop toggling.

3. While in Asynchronous mode, RDY will be low while the device is in embedded erase or programming mode.
