A29040A Series
The host system can detect whether a program or erase
operation is complete by reading the I/O7 (Data 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.
Pin Configurations
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.
Power consumption is greatly reduced when the device is
placed in the standby mode.
