Note:  
*This pin is a DC on the AT49BV002AN(T).  
When the device is deselected, the CMOS standby current is less than 50 µA. For the  
AT49BV002AN(T) pin 1 for the DIP and PLCC packages and pin 9 for the TSOP package are  
don’t connect pins. To allow for simple in-system reprogrammability, the AT49BV002A(N)(T)  
does not require high input voltages for programming. Five-volt-only commands determine the  
read and programming operation of the device. Reading data out of the device is similar to  
reading from an EPROM; it has standard CE, OE, and WE inputs to avoid bus contention.  
Reprogramming the AT49BV002A(N)(T) is performed by erasing a block of data and then pro-  
gramming on a byte by byte basis. The byte programming time is a fast 30 µs. The end of a  
program cycle can be optionally detected by the DATA polling feature. Once the end of a byte  
program cycle has been detected, a new access for a read or program can begin. The typical  
number of program and erase cycles is in excess of 10,000 cycles.  
The device is erased by executing the erase command sequence; the device internally con-  
trols the erase operations. There are two 8K byte parameter block sections, four main memory  
blocks, and one boot block.  
The device has the capability to protect the data in the boot block; this feature is enabled by a  
command sequence. The 16K-byte boot block section includes a reprogramming lock out fea-  
ture to provide data integrity. The boot sector is designed to contain user secure code, and  
when the feature is enabled, the boot sector is protected from being reprogrammed.  
In the AT49BV002AN(T), once the boot block programming lockout feature is enabled, the  
contents of the boot block are permanent and cannot be changed. In the AT49BV002A(T),  
once the boot block programming lockout feature is enabled, the contents of the boot block  
cannot be changed with input voltage levels of 5.5 volts or less.

3353B–FLASH–6/03  
AT49BV002A(N)(T)  
Device  
Operation  
READ: The AT49BV002A(N)(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 is 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 preventing bus contention.  
COMMAND SEQUENCES: When the device is first powered 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 sequences are entered into the device. The command  
sequences are shown in the Command Definitions table. 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. Standard microprocessor write timings are used.  
The address locations used in the command sequences are not affected by entering the com-  
mand sequences.  
RESET: A RESET input pin is provided to ease some system 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. If the RESET pin makes a high to low transition during a program or erase operation, the  
operation may not be successfully completed and the operation will have to be repeated after  
a high level is applied to the RESET pin. 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.  
By applying a 12V ± 0.5V input signal to the RESET pin, the boot block array can be repro-  
grammed even if the boot block lockout feature has been enabled (see Boot Block  
Programming Lockout Override section). The RESET feature is not available on the  
AT49BV002AN(T).  
ERASURE: Before a byte can be reprogrammed, the main memory blocks or parameter  
blocks which contains the byte must be erased. The erased state of the memory bits is a logi-  
cal “1”. The entire device can be erased at one time by using a 6-byte software code. The  
software chip erase code consists of 6-byte load commands to specific address locations with  
a specific data pattern (please refer to the Chip Erase Cycle Waveforms).  
After the software chip erase has been initiated, the device will internally time the erase opera-  
tion so that no external clocks are required. The maximum time needed to erase the whole  
chip is tEC. If the boot block lockout feature has been enabled, the data in the boot sector will  
not be erased.  
CHIP ERASE: If the boot block lockout has been enabled, the Chip Erase function will erase  
Parameter Block 1, Parameter Block 2, Main Memory Block 1 - 4, but not the boot block. If the  
Boot Block Lockout has not been enabled, the Chip Erase function will erase the entire chip.  
After the full chip erase the device will return back to read mode. Any command during chip  
erase will be ignored.  
SECTOR ERASE: As an alternative to a full chip erase, the device is organized into sectors  
that can be individually erased. There are two 8K-byte parameter block sections and four main  
memory blocks. The 8K-byte parameter block sections and the four main memory blocks can  
be independently erased and reprogrammed. 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 at 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 auto-  
matically time to completion.  
3
3353B–FLASH–6/03  
BYTE PROGRAMMING: Once the memory array is erased, the device is programmed (to a  
logical “0”) on a byte-by-byte basis. Please note that a data “0” cannot be programmed back to  
a “1”; only erase operations can convert “0”s to “1”s. Programming is accomplished via the  
internal device command register and is a 4 bus cycle operation (please refer to the Command  
Definitions table). The device will automatically generate the required internal program pulses.  
The program cycle has addresses latched on the falling edge of WE or CE, whichever occurs  
last, and the data latched on the rising edge of WE or CE, whichever occurs first. Program-  
ming is completed after the specified tBP cycle time. The DATA polling feature may also be  
used to indicate the end of a program cycle.  
BOOT BLOCK PROGRAMMING LOCKOUT: The device has one designated block that has  
a programming lockout feature. This feature prevents programming of data in the designated  
block once the feature has been enabled. The size of the block is 16K bytes. This block,  
referred to as the boot block, can contain secure code that is used to bring up the system.  
Enabling the lockout 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; the boot block’s usage as  
a write protected region is optional to the user. The address range of the boot block is 00000  
to 03FFF for the AT49BV002A(N) while the address range of the boot block is 3C000 to  
3FFFF for the AT49BV002A(N)T.  
Once the feature is enabled, the data in the boot block can no longer be erased or pro-  
grammed with input voltage of 5.5V or less. Data in the main memory block can still be  
changed through the regular programming method. To activate the lockout feature, a series of  
six program commands to specific addresses with specific data must be performed. Please  
refer to the Command Definitions table.  
BOOT BLOCK LOCKOUT DETECTION: A software method is available to determine if pro-  
gramming of the boot block section is locked out. When the device is in the software product  
identification mode (see Software Product Identification Entry and Exit sections) a read from  
address location 00002H will show if programming the boot block is locked out for the  
AT49BV002A(N), and a read from address location 3C002H will show if programming the  
bootblock is locked out for AT49BV002A(N)T. If the data on I/O0 is low, the boot block can be  
programmed; if the data on I/O0 is high, the program lockout feature has been activated and  
the block cannot be programmed. The software product identification code should be used to  
return to standard operation.  
BOOT BLOCK PROGRAMMING LOCKOUT OVERRIDE: The user can override the boot  
block programming lockout by taking the RESET pin to 12 volts during the entire chip erase,  
sector erase or byte programming operation. When the RESET pin is brought back to TTL lev-  
els the boot block programming lockout feature is again active. This feature is not available on  
the AT49BV002AN(T).  
PRODUCT IDENTIFICATION: The product identification mode identifies the device and man-  
ufacturer 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.  
For details, see Operating Modes (for hardware operation) or Software Product Identification.  
The manufacturer and device code is the same for both modes.

3353B–FLASH–6/03  
AT49BV002A(N)(T)  
DATA POLLING: The AT49BV002A(N)(T) features DATA polling to indicate the end of a pro-  
gram cycle. During a program cycle an attempted read of the last byte 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. DATA polling may begin at any time  
during the program cycle.  
TOGGLE BIT: In addition to DATA polling the AT49BV002A(N)(T) provides another method  
for determining the end of a program or erase cycle. During a program or erase operation,  
successive attempts to read data from the device 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.  
HARDWARE DATA PROTECTION: Hardware features protect against inadvertent programs  
to the AT49BV002A(N)(T) in the following ways: (a) VCC sense: if VCC is below 1.8V (typical),  
the program function is inhibited. (b) Program inhibit: holding any one of OE low, CE high or  
WE high inhibits program cycles. (c) Noise filter: pulses of less than 15 ns (typical) on the WE  
or CE inputs will not initiate a program cycle.
