GENERAL DESCRIPTION
The Am29LV128MH/L is a 128 Mbit, 3.0 volt single
power supply flash memory devices organized as
8,388,608 words or 16,777,216 bytes. The device has
a 16-bit wide data bus that can also function as an
8-bit wide data bus by using the BYTE# input. The de-
vice can be programmed either in the host system or
in standard EPROM programmers.
An access time of 90, 100, 110, or 120 ns is available.
Note that each access time 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 Order-
ing Information sections. The device is offered in a
56-pin TSOP, 64-ball Fortified BGA. Each device has
separate chip enable (CE#), write enable (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
(
WP#/
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

IO
pin.
Refer to the Ordering Information section for valid V

options.
Hardware data protection
measures include a low
V
CC
detector that automatically inhibits write opera-
tions during power transitions. The hardware sector
group protection feature disables both program and
erase operations in any combination of sector groups
of memory. This can be achieved in-system or via pro-
gramming 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 Sus-
pend/Program Resume
feature enables the host sys-
tem to pause a program operation in a given sector to
read any other sector and then complete the program
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
128-word/256-byte area for code or data that can be
permanently protected. Once this sector is protected,
no further changes within the sector can occur.
The
Write Protect (WP#
/ACC
)
feature protects the
first or last sector by asserting a logic low on the WP#
pin.
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.
