GENERAL DESCRIPTION

The Am29LV320MH/L is a 32 Mbit, 3.0 volt single

power supply flash memory device organized as

2,097,152 words or 4,194,304 bytes. The device has

an 8-bit/16-bit bus and 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

) and an I/O voltage range (V

), as

specified in the

Product Selector Guide

and the

Order-

ing Information

sections. The device is offered in a

56-pin TSOP or 64-ball Fortified BGA package. 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

input, a high-voltage

accelerated program

(ACC)

feature provides shorter programming times

through increased current on the WP#/ACC input. This

feature is intended to facilitate factory throughput dur-

ing 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

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™

) 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

pin.

Refer to the

Ordering Information

section for valid V

options.

Hardware data protection

measures include a low

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 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

Write Protect (WP#)

feature protects the first or

last sector by asserting a logic low on the WP#/ACC

pin. The protected sector will still be protected even

during accelerated programming.

The

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.

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.
