GENERAL DESCRIPTION
The AS29LV016 is a 16 Mbit, 3.0 Volt-only Flash
memory organized as 2,097,152 bytes or
1,048,576 words. The word-wide data (x16)
appears on DQ15–DQ0; the byte-wide (x8) data
appears on DQ7–DQ0. This device is designed to
be programmed in-system with the standard
system 3.0 volt V
CC
supply. A 12.0 V V
PP
or 5.0
V
CC
are not required for write or erase operations.
The device can also be programmed in standard
EPROM programmers.
The device offers access times of 70 ns, 90 ns
and 100 ns 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 3.0 volt power
supply
for both read and write functions. Internally
generated and regulated voltages are provided
for the program and erase operations.
The AS29LV016 is entirely 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 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 executing the
program command sequence. This initiates the
Embedded Program
algorithm—an internal
algorithm that automatically times the program
pulse widths and verifies proper cell margin. The
Unlock Bypass
mode facilitates faster programming
times by requiring only two write cycles to program
data instead of four.
Device erasure occurs by executing the erase
command sequence. This initiates the
Embedded
Erase
algorithm—an internal algorithm that
automatically preprograms the array (if it is not
AS29LV016
Rev. 2.1 10/08
already programmed) before executing the erase
operation. During erase, the device automatically
times the erase pulse widths and verifies proper
cell margin.
The host system can detect whether a program
or erase operation is complete by observing the
RY/BY# pin, or by reading the DQ7 (Data# Polling)
and DQ6 (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
device is fully erased when shipped from the
factory.
Hardware data protection
measures include a low
V
CC
detector that automatically inhibits write
operations during power transitions. The
hardware
sector protection
feature disables both program
and erase operations in any combination of the
sectors of memory. This can be achieved in-system
or 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
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.
