GENERAL DESCRIPTION
The Am29LV033MU is a 32 Mbit, 3.0 volt single power
supply flash memory devices organized as 4,194,304
bytes. The device has an 8-bit wide data bus, and can
be programmed either in the host system or in stan-
dard EPROM programmers.
The device is available with an access time of 90, 100,
110, or 120 ns. Note that each device has a specific
operating voltage range (V
CC
) and an I/O voltage
range (V
IO
), as specified in the
Product Selector Guide
and the
Ordering Information
sections. The device is
offered in a 40-pin TSOP or 48-ball FBGA package.
Each device has separate chip enable (CE#), write en-
able (WE#) and output enable (OE#) controls.
Each device requires only a
single 3.0 volt power
supply
for both read and write functions. In addition to
a V
CC
input, a high-voltage
accelerated program
(ACC)
input provides shorter programming times
through increased current. This feature is intended to
facilitate factory throughput during system production,
but may also be used in the field if desired.
The device is entirely command set compatible with
the
JEDEC single-power-supply Flash standard
.
Commands are written to the device using standard
microprocessor write timing. Write cycles also inter-
nally latch addresses and data needed for the pro-
gramming and erase operations.
The
sector erase architecture
allows memory sec-
tors to be erased and reprogrammed without affecting
the data contents of other sectors. The device is fully
erased when shipped from the factory.
Device programming and erasure are initiated through
command sequences. Once a program or erase oper-
ation has begun, the host system need only poll the
DQ7 (Data# Polling) or DQ6 (toggle)
status bits
or
monitor the
Ready/Busy# (RY/BY#)
output to deter-
mine whether the operation is complete. To facilitate
programming, an
Unlock Bypass
mode reduces com-
mand sequence overhead by requiring only two write
cycles to program data instead of four.
The
VersatileI/O
(V
IO
) control allows the host sys-
tem to set the voltage levels that the device generates
and tolerates on the CE# control input and DQ I/Os to
the same voltage level that is asserted on the V
IO
pin.
Refer to the
Ordering Information
section for valid V
IO
options.
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 sectors of memory.
This can be achieved in-system or via programming
equipment.
The
Erase Suspend/Erase Resume
feature allows
the host system to pause an erase operation in a
given sector to read or program any other sector and
then complete the erase operation. The
Program
Suspend/Program Resume
feature enables the host
system to pause a program operation in a given sector
to read any other sector and then complete the pro-
gram operation.
The
hardware RESET# pin
terminates any operation
in progress and resets the device, after which it is then
ready for a new operation. The RESET# pin may be
tied to the system reset circuitry. A system reset would
thus also reset the device, enabling the host system to
read boot-up firmware from the Flash memory device.
The device reduces power consumption in the
standby mode
when it detects specific voltage levels
on CE# and RESET#, or when addresses have been
stable for a specified period of time.
The
SecSi
(Secured Silicon) Sector
provides a
256 byte area for code or data that can be perma-
nently protected. Once this sector is protected, no fur-
ther changes within the sector can occur.
AMD MirrorBit flash technology combines years of
Flash memory manufacturing experience to produce
the highest levels of quality, reliability and cost effec-
tiveness. The device electrically erases all bits within a
sector simultaneously via hot-hole assisted erase. The
data is programmed using hot electron injection.
