GENERAL DESCRIPTION
The Am29LV320D is a 32 megabit, 3.0 volt-only flash
memory device, organized as 2,097,152 words of 16
bits each or 4,194,304 bytes of 8 bits each. Word
mode data appears on DQ0–DQ15; byte mode data
appears on DQ0–DQ7. The device is designed to be
programmed in-system with the standard 3.0 volt V
CC
supply, and can also be programmed in standard
EPROM programmers.
The device is available with an access time of 90 or
120 ns. The devices are offered in 48-pin TSOP and
48-ball FBGA packages. Standard control pins—chip
enable (CE#), write enable (WE#), and output enable
(OE#)—control normal read and write operations, and
avoid bus contention issues.
The device requires only a single 3.0 volt power sup-
ply for both read and write functions. Internally gener-
ated and regulated voltages are provided for the
program and erase operations.
Am29LV320D Features
The SecSi
TM Sector (Security on Silicon) is an extra
sector capable of being permanently locked by AMD
or customers. The SecSi Indicator Bit (DQ7) is per-
manently set to a 1 if the part is factory locked, and
set to a 0 if customer lockable. This way, customer
lockable parts can never be used to replace a factory
locked part. Current version of device has 64
Kbytes; future versions will have only 256 bytes.
This should be considered during system design.
Factory locked parts provide several options. The
SecSi Sector may store a secure, random 16 byte
ESN (Electronic Serial Number), customer code (pro-
grammed through AMD’s ExpressFlash service), or
both. Customer Lockable parts may utilize the SecSi
Sector as bonus space, reading and writing like any
other flash sector, or may permanently lock their own
code there.
The device offers complete compatibility with the
JEDEC single-power-supply Flash command set
standard. Commands are written to the command
register using standard microprocessor write timings.
Reading data out of the device is similar to reading
from other Flash or EPROM devices.
The host system can detect whether a program or
erase operation is complete by using the device sta-
tus bits: RY/BY# pin, DQ7 (Data# Polling) and
DQ6/DQ2 (toggle bits). After a program or erase cycle
has been completed, the device automatically returns
to the read mode.
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.
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 in-system or via program-
ming equipment.
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.
T he sys tem can also place the device into the
standby mode. Power consumption is greatly re-
duced in both modes.
