The device contains a user-enabled “boot block” protection
feature. Two versions of the feature are available: the
AT49BV/LV8192 locates the boot block at lowest order
addresses (“bottom boot”); the AT49BV/LV8192T locates it
at highest order addresses (“top boot”)
To allow for simple in-system reprogrammability, the
AT49BV/LV8192 does not require high input voltages for
programming. 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
AT49BV/LV8192 is performed by first erasing a block of
data and then programming on a word-by-word basis.
The device is erased by executing the erase command
sequence; the device internally controls the erase operation. The memory is divided into three blocks for erase
operations. There are two 8K word parameter block sections and one sector consisting of the boot block and the
main memory array block. The AT49BV/LV8192 is programmed on a word-by-word basis.
The device has the capability to protect the data in the boot
block; this feature is enabled by a command sequence.
Once the boot block programming lockout feature is
enabled, the data in the boot block cannot be changed
when input levels of 3.6 volts or less are used. The typical
number of program and erase cycles is in excess of 10,000
cycles.
The optional 8K word boot block section includes a reprogramming lock out feature 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.
During a chip erase, sector erase, or word programming,
the VPP pin must be at 5V ± 10%.

Device Operation
READ: The AT49BV/LV8192 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
(I/O8 - I/O15 are don't care inputs for the command codes).
The command sequences are written by applying a low
2
AT49BV/LV8192(T)
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 command 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. 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
AT49BV/LV8192(T)
signal to the RESET pin the boot block array can be reprogrammed even if the boot block program lockout feature
has been enabled (see Boot Block Programming Lockout
Override section).
ERASURE: Before a word can be reprogrammed, it must
be erased. The erased state of memory bits is a logical “1”.
The entire device can be erased by using the Chip Erase
command or individual sectors can be erased by using the
Sector Erase commands.
CHIP ERASE: The entire device can be erased at one
time by using the 6-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.
The maximum time to erease the chip is tEC.
If the boot block lockout has been enabled, the Chip Erase
will not erase the data in the boot block; it will erase the
main memory block and the parameter blocks only. 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 three sectors that can be individually erased. There are two 8K word parameter block
sections and one sector consisting of the boot block and
the main memory array block. 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
automatically time to completion. When the boot block programming lockout feature is not enabled, the boot block
and the main memory block will erase together (from the
same sector erase command). Once the boot region has
been protected, only the main memory array sector will
erase when its sector erase command is issued.
WORD PROGRAMMING: Once a memory block is
erased, it is programmed (to a logical “0”) on a word-byword basis. Programming is accomplished via the internal
device command register and is a 4 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 happens 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 “0”s to “1”s. Programming 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 8K words. 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
49BV/LV8192 boot block is 00000H to 01FFFH while the
address range of the 49BV/LV8192T is 7E000H to
7FFFFH.
Once the feature is enabled, the data in the boot block can
no longer be erased or programmed when input levels of
5.5V or less are used. 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 programming 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. 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 enabled and the block cannot be programmed. The software product identification exit 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 word programming operation. When the RESET pin is brought back to TTL levels
the boot block programming lockout feature is again active.
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.
For details, see Operating Modes (for hardware operation)
or Software Product Identification. The manufacturer and
device code is the same for both modes.
DATA POLLING: The AT49BV/LV8192 features DATA
polling to indicate the end of a program 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. During a chip
or sector erase operation, an attempt to read the device will
give a “0” on I/O7. Once the program or erase cycle has
completed, true data will be read from the device. DATA
polling may begin at any time during the program cycle.
3
TOGGLE BIT: In addition to DATA polling the
AT49BV/LV8192 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
AT49BV/LV8192 in the following ways: (a) V CC sense: if
VCC is below 1.8V (typical), the program function is inhib-
4
AT49BV/LV8192(T)
ited. (b) V CC power on delay: once V CC 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.
INPUT LEVELS: While operating with a 2.7V 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.
