A29040A Series  
The host system can detect whether a program or erase  
operation is complete by reading the I/O7 ( Polling) and  
I/O6 (toggle) status bits. After a program or erase cycle has  
been completed, the device is ready to read array data or  
accept another command.  
The sector erase architecture allows memory sectors to be  
erased and reprogrammed without affecting the data contents  
of other sectors. The A29040A is fully erased when shipped  
from the factory.  
The hardware sector protection feature disables operations  
for both program and erase in any combination of the sectors  
of memory. This can be achieved via programming  
equipment.  
The Erase Suspend feature enables the user to put erase on  
hold for any period of time to read data from, or program data  
to, any other sector that is not selected for erasure. True  
background erase can thus be achieved.  
Data  
Power consumption is greatly reduced when the device is  
placed in the standby mode.
