The device powers on in the read mode. Command  
sequences are used to place the device in other operation  
modes such as program and erase. The device has the  
capability to protect the data in any sector. (See “Sector  
Lockdown” section.)  
The VPP pin provides data protection and faster program-  
ming. When the VPP input is below 0.8V, the program and  
erase functions are inhibited. When VPP is at 1.65V or  
above, normal program and erase operations can be per-  
formed. With VPP at 5.0V or 12.0V, the program and erase  
operations are accelerated.  
To increase the flexibility of the device, it contains an Erase  
Suspend and Program Suspend feature. This feature will  
put the Erase or Program on hold for any amount of time  
and let the user read data from or program data to any of  
the remaining sectors within the memory. The end of a pro-  
gram or an erase cycle is detected by the Ready/Busy pin,  
Data Polling or by the toggle bit.  
A six-byte command (Enter Single Pulse Program Mode)  
sequence to remove the requirement of entering the three-  
byte program sequence is offered to further improve pro-  
gramming time. After entering the six-byte code, only single  
pulses on the write control lines are required for writing into  
the device. This mode (Single Pulse Byte/Word Program)  
AT49BV/LV160(T)/161(T)  
2
AT49BV/LV160(T)/161(T)  
is exited by powering down the device, or by pulsing the  
RESET pin low for a minimum of 50 ns and then bringing it  
back to VCC. Erase, Erase Suspend/Resume, and Program  
Suspend/Resume commands will not work while in this  
mode; if entered they will result in data being programmed  
into the device. It is not recommended that the six-byte  
code reside in the software of the final product but only  
exist in external programming code.  
AT49BV/LV161(T) configuration, the BYTE pin controls  
whether the device data I/O pins operate in the byte or  
word configuration. If the BYTE pin is set at logic 1, the  
device is in word configuration, I/O0 - I/O15 are active and  
controlled by CE and OE.  
If the BYTE pin is set at logic 0, the device is in byte con-  
figuration, and only data I/O pins I/O0 - I/O7 are active and  
controlled by CE and OE. The data I/O pins I/O8 - I/O14  
are tri-stated, and the I/O15 pin is used as an input for the  
LSB (A-1) address function.  
When using the AT49BV/LV160(T) pinout configuration,  
the device always operates in the word mode. In the

Device Operation  
READ: The AT49BV/LV16X(T) is accessed like an  
EPROM. When CE and OE are low and WE is high, the  
data stored at the memory location determined by the  
address pins are asserted on the outputs. The outputs are  
put in the high-impedance state whenever CE or OE is  
high. This dual-line control gives designers flexibility in pre-  
venting bus contention.  
sequences are entered into the device. The command  
sequences are shown in the Command Definition in Hex”  
table on page 10 (I/O8 - I/O15 are dont care inputs for the  
command codes). The command sequences are written by  
applying a low pulse on the WE or CE input with CE or WE  
low (respectively) and OE high. The address is latched on  
the falling edge of CE or WE, whichever occurs last. The  
data is latched by the first rising edge of CE or WE. Stan-  
dard microprocessor write timings are used. The address  
locations used in the command sequences are not affected  
by entering the command sequences.  
COMMAND SEQUENCES: When the device is first pow-  
ered on, it will be reset to the read or standby mode,  
depending upon the state of the control line inputs. In order  
to perform other device functions, a series of command  
3
RESET: A RESET input pin is provided to ease some sys-  
tem applications. When RESET is at a logic high level, the  
device is in its standard operating mode. A low level on the  
RESET input halts the present device operation and puts  
the outputs of the device in a high-impedance state. When  
a high level is reasserted on the RESET pin, the device  
returns to the read or standby mode, depending upon the  
state of the control inputs.  
VPP PIN: The circuitry of the AT49BV/LV16X(T) is  
designed so that the device can be programmed or erased  
from the VCC power supply or from the VPP input pin. When  
VPP is greater than 1.65V and less than or equal to the VCC  
pin, the device selects the VCC supply for programming and  
erase operations. When the VPP pin is greater than the  
VCC supply, the device will select the VPP input as the  
power supply for programming and erase operations. The  
device will allow for some variations between the VPP input  
and the VCC power supply in its selection of VCC or VPP for  
program or erase operations. If the VPP pin is within 0.3V  
of VCC for 2.65V < VCC < 3.6V, then the program or erase  
operations will use VCC and disregard the VPP input signal.  
When the VPP signal is used for program and erase opera-  
tions, the VPP must be in the 5V 0.5V or 12V 0.5V range  
to ensure proper operation. The Vpp pin cannot be left  
floating.  
ERASURE: Before a byte/word can be reprogrammed, it  
must be erased. The erased state of memory bits is a logi-  
cal 1. The entire device can be erased by using the Chip  
Erase command or individual sectors can be erased by  
using the Sector Erase command.  
CHIP ERASE: The entire device can be erased at one time  
by using the six-byte chip erase software code. After the  
chip erase has been initiated, the device will internally time  
the erase operation so that no external clocks are required.  
PROGRAM/ERASE STATUS: The device provides sev-  
eral bits to determine the status of a program or erase  
operation: I/O2, I/O3, I/O5, I/O6 and I/O7. The Status Bit  
Tableon page 9 and the following four sections describe  
the function of these bits. To provide greater flexibility for  
system designers, the AT49BV/LV16X(T) contains a pro-  
grammable configuration register. The configuration  
register allows the user to specify the status bit operation.  
The configuration register can be set to one of two different  
values, 00or 01. If the configuration register is set to  
00, the part will automatically return to the read mode  
after a successful program or erase operation. If the config-  
uration register is set to a 01, a Product ID Exit command  
must be given after a successful program or erase opera-  
tion before the part will return to the read mode. It is  
important to note that whether the configuration register is  
set to a 00or to a 01, any unsuccessful program or  
erase operation requires using the Product ID Exit com-  
mand to return the device to read mode. The default value  
(after power-up) for the configuration register is 00. Using  
the four-bus cycle Set Configuration Register command as  
shown in the Command Definition in Hextable on  
page 10, the value of the configuration register can be  
changed. Voltages applied to the RESET pin will not alter  
the value of the configuration register. The value of the  
configuration register will affect the operation of the I/O7  
status bit as described below.  
The maximum time to erase the chip is tEC  
.
If the sector lockdown has been enabled, the chip erase  
will not erase the data in the sector that has been locked  
out; it will erase only the unprotected sectors. After the chip  
erase, the device will return to the read or standby mode.  
SECTOR ERASE: As an alternative to a full chip erase, the  
device is organized into 39 sectors (SA0 - SA38) that can  
be individually erased. The Sector Erase command is a six-  
bus cycle operation. The sector address is latched on the  
falling WE edge of the sixth cycle while the 30H data input  
command is latched on the rising edge of WE. The sector  
erase starts after the rising edge of WE of the sixth cycle.  
The erase operation is internally controlled; it will automati-  
cally time to completion. The maximum time to erase a  
sector is tSEC. When the sector programming lockdown fea-  
ture is not enabled, the sector will erase (from the same  
Sector Erase command). An attempt to erase a sector that  
has been protected will result in the operation terminating  
in 2 µs.  
BYTE/WORD PROGRAMMING: Once a memory block is  
erased, it is programmed (to a logical 0) on a byte-by-byte  
or on a word-by-word basis. Programming is accomplished  
via the internal device command register and is a four-bus  
cycle operation. The device will automatically generate the  
required internal program pulses.  
Any commands written to the chip during the embedded  
programming cycle will be ignored. If a hardware reset hap-  
pens during programming, the data at the location being  
programmed will be corrupted. Please note that a data 0”  
cannot be programmed back to a 1; only erase operations  
can convert 0s to 1s. Programming is completed after  
the specified tBP cycle time. The Data Polling feature or the  
Toggle Bit feature may be used to indicate the end of a pro-  
gram cycle. If the erase/program status bit is a 1, the  
device was not able to verify that the erase or program  
operation was performed successfully.  
DATA POLLING: The AT49BV/LV16X(T) features Data  
Polling to indicate the end of a program cycle. If the status  
configuration register is set to a 00, during a program  
cycle an attempted read of the last byte/word loaded will  
result in the complement of the loaded data on I/O7. Once  
the program cycle has been completed, true data is valid  
on all outputs and the next cycle may begin. During a chip  
or sector erase operation, an attempt to read the device will  
give a 0on I/O7. Once the program or erase cycle has  
completed, true data will be read from the device. Data

tion successfully, the VPP status bit will output a 0. Please  
see Status Bit Tableon page 9 for more details.  
If the status bit configuration register is set to a 01, the  
I/O7 status bit will be low while the device is actively pro-  
gramming or erasing data. I/O7 will go high when the  
device has completed a program or erase operation. Once  
I/O7 has gone high, status information on the other pins  
can be checked.  
SECTOR LOCKDOWN: Each sector has a programming  
lockdown feature. This feature prevents programming of  
data in the designated sectors once the feature has been  
enabled. These sectors can contain secure code that is  
used to bring up the system. Enabling the lockdown feature  
will allow the boot code to stay in the device while data in  
the rest of the device is updated. This feature does not  
have to be activated; any sectors usage as a write-  
protected region is optional to the user.  
The Data Polling status bit must be used in conjunction  
with the erase/program and VPP status bit as shown in the  
algorithm in Figures 1 and 2 on page 7.  
At power-up or reset, all sectors are unlocked. To activate  
the lockdown for a specific sector, the six-bus cycle Sector  
Lockdown command must be issued. Once a sector has  
been locked down, the contents of the sector is read-only  
and cannot be erased or programmed.  
TOGGLE BIT: In addition to Data Polling, the  
AT49BV/LV16X(T) provides another method for determin-  
ing the end of a program or erase cycle. During a program  
or erase operation, successive attempts to read data from  
the memory will result in I/O6 toggling between one and  
zero. Once the program cycle has completed, I/O6 will stop  
toggling and valid data will be read. Examining the toggle  
bit may begin at any time during a program cycle. Please  
see Status Bit Tableon page 9 for more details.  
SECTOR LOCKDOWN DETECTION: A software method  
is available to determine if programming of a sector is  
locked down. When the device is in the software product  
identification mode (see Software Product Identification  
Entry/Exitsections on page 20), a read from address loca-  
tion 00002H within a sector will show if programming the  
sector is locked down. If the data on I/O0 is low, the sector  
can be programmed; if the data on I/O0 is high, the pro-  
gram lockdown feature has been enabled and the sector  
cannot be programmed. The software product identification  
exit code should be used to return to standard operation.  
The toggle bit status bit should be used in conjunction with  
the erase/program and VPP status bit as shown in the algo-  
rithm in Figures 3 and 4 on page 8.  
ERASE/PROGRAM STATUS BIT: The device offers a sta-  
tus bit on I/O5, which indicates whether the program or  
erase operation has exceeded a specified internal pulse  
count limit. If the status bit is a 1, the device is unable to  
verify that an erase or a byte/word program operation has  
been successfully performed. The device may also output  
a 1on I/O5 if the system tries to program a 1to a loca-  
tion that was previously programmed to a 0. Only an  
erase operation can change a 0back to a 1. If a pro-  
gram (Sector Erase) command is issued to a protected  
sector, the protected sector will not be programmed  
(erased). The device will go to a status read mode and the  
I/O5 status bit will be set high, indicating the program  
(erase) operation did not complete as requested. Once the  
erase/program status bit has been set to a 1, the system  
must write the Product ID Exit command to return to the  
read mode. The erase/program status bit is a 0while the  
erase or program operation is still in progress. Please see  
Status Bit Tableon page 9 for more details.  
SECTOR LOCKDOWN OVERRIDE: The only way to  
unlock a sector that is locked down is through reset or  
power-up cycles. After power-up or reset, the content of a  
sector that is locked down can be erased and  
reprogrammed.  
ERASE SUSPEND/ERASE RESUME: The Erase Sus-  
pend command allows the system to interrupt a sector  
erase or chip erase operation and then program or read  
data from a different sector within the memory. After the  
Erase Suspend command is given, the device requires a  
maximum time of 15 µs to suspend the erase operation.  
After the erase operation has been suspended, the system  
can then read data or program data to any other sector  
within the device. An address is not required during the  
Erase Suspend command. During a sector erase suspend,  
another sector cannot be erased. To resume the sector  
erase operation, the system must write the Erase Resume  
command. The Erase Resume command is a one-bus  
cycle command. The device also supports an erase sus-  
pend during a complete chip erase. While the chip erase is  
suspended, the user can read from any sector within the  
memory that is protected. The command sequence for a  
chip erase suspend and a sector erase suspend are the  
same.  
VPP STATUS BIT: The AT49BV/LV16X(T) provides a sta-  
tus bit on I/O3, which provides information regarding the  
voltage level of the VPP pin. During a program or erase  
operation, if the voltage on the VPP pin is not high enough  
to perform the desired operation successfully, the I/O3 sta-  
tus bit will be a 1. Once the VPP status bit has been set to  
a 1, the system must write the Product ID Exit command  
to return to the read mode. On the other hand, if the voltage  
level is high enough to perform a program or erase opera-  
5
PROGRAM SUSPEND/PROGRAM RESUME: The Pro-  
gram Suspend command allows the system to interrupt a  
programming operation and then read data from a different  
byte/word within the memory. After the Program Suspend  
command is given, the device requires a maximum of 15 µs  
to suspend the programming operation. After the program-  
ming operation has been suspended, the system can then  
read data from any other byte/word within the device. An  
address is not required during the program suspend opera-  
tion. To resume the programming operation, the system  
must write the Program Resume command. The program  
suspend and resume are one-bus cycle commands. The  
command sequence for the erase suspend and program  
suspend are the same, and the command sequence for the  
erase resume and program resume are the same.  
80H. If data bit D1 is zero, block B is locked. If data bit D1 is  
one, block B can be reprogrammed. Please see the Pro-  
tection Register Addressing Tableon page 11 for the  
address locations in the protection register. To read the  
protection register, the Product ID Entry command is given  
followed by a normal read operation from an address within  
the protection register. After determining whether block B is  
protected or not, or reading the protection register, the  
Product ID Exit command must be given prior to performing  
any other operation.  
RDY/BUSY: An open-drain READY/BUSY output pin pro-  
vides another method of detecting the end of a program or  
erase operation. RDY/BUSY is actively pulled low during  
the internal program and erase cycles and is released at  
the completion of the cycle. The open-drain connection  
allows for OR-tying of several devices to the same  
RDY/BUSY line. Please see Status Bit Tableon page 9  
for more details.  
PRODUCT IDENTIFICATION: The product identification  
mode identifies the device and manufacturer as Atmel. It  
may be accessed by hardware or software operation. The  
hardware operation mode can be used by an external  
programmer to identify the correct programming algorithm  
for the Atmel product.  
HARDWARE DATA PROTECTION: The Hardware Data  
Protection feature protects against inadvertent programs to  
the AT49BV/LV16X(T) in the following ways: (a) VCC  
sense: if VCC is below 1.8V (typical), the program function  
is inhibited. (b) VCC power-on delay: once VCC has reached  
the VCC sense level, the device will automatically time out  
10 ms (typical) before programming. (c) Program inhibit:  
holding any one of OE low, CE high or WE high inhibits  
program cycles. (d) Noise filter: pulses of less than 15 ns  
(typical) on the WE or CE inputs will not initiate a program  
cycle. (e) Program inhibit: VPP is less than VILPP. (f) VPP  
power-on delay: once VPP has reached 1.65V, program and  
erase operations can occur after 100 ns.  
For details, see Operating Modeson page 14 (for hard-  
ware operation) or Software Product Identification

128-BIT  
PROTECTION  
REGISTER:  
The  
AT49BV/LV16X(T) contains a 128-bit register that can be  
used for security purposes in system design. The protec-  
tion register is divided into two 64-bit blocks. The two  
blocks are designated as block A and block B. The data in  
block A is non-changeable and is programmed at the fac-  
tory with a unique number. The data in block B is  
programmed by the user and can be locked out such that  
data in the block cannot be reprogrammed. To program  
block B in the protection register, the four-bus cycle Pro-  
gram Protection Register command must be used as  
shown in the Command Definition in Hextable on  
page 10. To lock out block B, the four-bus cycle Lock Pro-  
tection Register command must be used as shown in the  
Command Definition in Hextable on page 10. Data bit D1  
must be zero during the fourth bus cycle. All other data bits  
during the fourth bus cycle are dont cares. To determine  
whether block B is locked out, the Product ID Entry com-  
mand is given followed by a read operation from address  
INPUT LEVELS: While operating with a 2.65V to 3.6V  
power supply, the address inputs and control inputs (OE,  
CE and WE) may be driven from 0 to 5.5V without  
adversely affecting the operation of the device. The I/O  
lines can only be driven from 0 to VCC + 0.6V.  
OUTPUT LEVELS: For the AT49BV/LV160(T), output high  
levels (VOH) are equal to VCCQ - 0.2V (not VCC). For 2.65V -  
3.6V output levels, VCCQ must be tied to VCC. For 1.8V -  
2.2V output levels, VCCQ must be regulated to 2.0V 10%,  
while VCC must be regulated to 2.65V - 3.0V (for minimum  
power).

Notes: 1. The DATA FORMAT shown for each bus cycle is as follows; I/O7 - I/O0 (Hex). In word operation I/O15 - I/O8 are Dont Care.  
The ADDRESS FORMAT shown for each bus cycle is as follows: A11 - A0 (Hex). Address A19 through A11 are Dont Care  
in the word mode. Address A19 through A11 and A-1 are Dont Care in the byte mode.  
2. Since A11 is a Dont Care, AAA can be replaced with 2AA.  
3. SA = sector address. Any byte/word address within a sector can be used to designate the sector address (see pages 12 and  
13 for details).  
4. Once a sector is in the lockdown mode, data in the protected sector cannot be changed unless the chip is reset or power  
cycled.  
5. Either one of the Product ID Exit commands can be used.  
6. If data bit D1 is 0, block B is locked. If data bit D1 is 1, block B can be reprogrammed.  
7. The default state (after power-up) of the configuration register is 00.
