GENERAL DESCRIPTION
The Am29F016D is a 16 Mbit, 5.0 volt-only Flash mem-
ory organized as 2,097,152 bytes. The 8 bits of data
appear on DQ0–DQ7. The Am29F016D is offered in
48-pin TSOP, 40-pin TSOP, and 44-pin SO packages.
The device is also available in Known Good Die (KGD)
form. For more information, refer to publication number
21551. This device is designed to be programmed
in-system with the standard system 5.0 volt V
CC
supply.
A 12.0 volt V
PP
is not required for program or erase
operations. The device can also be programmed in
standard EPROM programmers.
This device is manufactured using AMD’s 0.23 µm pro-
cess technology, and offers all the features and
benefits of the Am29F016, which was manufactured
using 0.5 µm process technology.
The standard device offers access times of 70, 90, and
120 ns, allowing high-speed microprocessors to oper-
ate 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 5.0 volt power sup-
ply
for both read and write functions. Internally
generated and regulated voltages are provided for the
program and erase operations.
The device is entirely command set compatible with the
JEDEC single-power-supply Flash standard.
Com-
mands are written to the command register using
standard microprocessor write timings. Register con-
tents serve as input to an internal state-machine that
controls the erase and programming circuitry. Write cy-
cles 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 auto-
matically times the program pulse widths and verifies
proper cell margin.
Device erasure occurs by executing the erase com-
mand 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 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 opera-
tions during power transitions. The
hardware sector
protection
feature disables both program and erase
operations in any combination of the sectors of mem-
ory. 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 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 system can place the device into the
standby
mode.
Power consumption is greatly reduced in
this mode.
AMD’s Flash technology combines years of Flash
memory manufacturing experience to produce the
highest levels of quality, reliability and cost effective-
ness. The device electrically erases all bits within a
sector simultaneously via Fowler-Nordheim tunneling.
The data is programmed using hot electron injection.
