A29002/A290021 Series

The host system can detect whether a program or erase of memory. This can be achieved via programming

equipment.

operation is complete by reading the I/O7 (

Polling) and

Data

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.

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 A29002 is fully erased when shipped

from the factory.

The hardware

pin terminates any operation in

The hardware sector protection feature disables operations

for both program and erase in any combination of the

progress and resets the internal state machine to reading

array data (This feature is not available on the A290021).
