A29L004A Series
available on 32-pin PLCC & (s)TSOP), 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 A29L004A 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 (not available on 32-pin PLCC & (s)TSOP). 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 two power-saving features. When
addresses have been stable for a specified amount of time,
the device enters the automatic sleep mode. The system can
also place the device into the standby mode. Power
consumption is greatly reduced in both these modes.
