A29400 Series
PRELIMINARY
(February, 2001, Version 0.1)
2
AMIC Technology, Inc.
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 A29400 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
Pin Configurations
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.
The hardware RESET pin terminates any operation in
progress and resets the internal state machine to reading
array data.
