General Description
The A29L320A is a 32Mbit, 3.3 volt-only Flash memory
organized as 2,097,152 words of 16 bits or 4,194,304 bytes
of 8 bits each. The 8 bits of data appear on I/O0 - I/O7; the 16
bits of data appear on I/O0~I/O15. The A29L320A is offered in
48-ball TFBGA and 48-Pin TSOP packages. This device is
designed to be programmed in-system with the standard
system 3.3 volt VCC supply. Additional 12.0 volt VPP is not
required for in-system write or erase operations. However,
the A29L320A can also be programmed in standard EPROM
programmers.
The A29L320A has the first toggle bit, I/O6, which indicates
whether an Embedded Program or Erase is in progress, or it
is in the Erase Suspend. Besides the I/O6 toggle bit, the
A29L320A has a second toggle bit, I/O2, to indicate whether
the addressed sector is being selected for erase. The
A29L320A also offers the ability to program in the Erase
Suspend mode. The standard A29L320A offers access times
of 70,80,90 and 120ns, allowing high-speed microprocessors
to operate without wait states. To eliminate bus contention
the device has separate chip enable ( CE ), write enable
( WE ) and output enable ( OE ) controls.
The device requires only a single 3.3 volt power supply for
both read and write functions. Internally generated and
regulated voltages are provided for the program and erase
operations.
The A29L320A is entirely software command set compatible
with the JEDEC single-power-supply Flash standard.
Commands are written to the command register using
standard microprocessor write timings. Register contents

 A29L320A
A29L320A Series
serve as input to an internal state-machine that controls the
erase and programming circuitry. Write cycles also internally
latch addresses and data needed for the programming and
erase operations. Reading data out of the device is similar to
reading from other Flash or EPROM devices.
Device programming occurs by writing the proper program
command sequence. This initiates the Embedded Program
algorithm - an internal algorithm that automatically times the
program pulse widths and verifies proper program margin.
Device erasure occurs by executing the proper erase
command sequence. This initiates the Embedded Erase
algorithm - an internal algorithm that automatically
preprograms the array (if it is not already programmed)
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 A29L320A 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 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.
