A29800A Series
before executing the erase operation. During erase, the
device automatically times the erase pulse widths and
verifies proper erase margin. The Unlock Bypass mode
facilitates faster programming times by requiring only two
write cycles to program data instead of four.
The host system can detect whether a program or erase
operation is complete by observing the RY / BY pin, or 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 A29800A 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/Erase Resume 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.
The hardware RESET pin terminates any operation in
progress and resets the internal state machine to reading
array data. The RESET pin may be tied to the system reset
circuitry. A system reset would thus also reset the device,
enabling the system microprocessor to read the boot-up
firmware from the Flash memory.
The device offers power-saving features. The system can
place the device into the standby mode. Power consumption
is greatly reduced in standby mode.
