The device contains a u se r-e nabl ed “ boo t b lock ” pr ote ct ion feature. Two versions of the feature are available: the AT49BV/LV8192 locates the boot block at lowest or der addresses (“bottom boot ”); the AT49 BV/LV 8192T locate s 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 i s similar to reading from an E PROM ; it h as stan dard CE
, OE, and WE inputs to avoid bus contention. Reprogramming the AT49BV/LV8192 is perfor med 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 di vided into three bl ocks 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. T he 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 bl ock cannot be cha nged 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 o ut featur e to pro vide data i ntegrity. The boot sector is des igned to contain us er 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 V
pin must be at 5V ± 10%.

Device Operation
READ:
When CE at the memory location determined by the address pins is asserted on the outputs . The outputs ar e put in the high impedance state whenever CE control gives designers flexibility in preventing bus conten­tion.
COMMAND SEQUENCES:
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 sequences are entered into the device. The command sequences are shown in the Comma nd Definitions ta ble (I/O8 - I/O15 are don't care inputs for the command codes). The command sequences are written by applying a low

If the boot block lockout ha s b een ena bled, th e Chip Era se 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, th e d ev ice will return to the r ea d or s tand by mode.
SECTOR 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 blo ck. The Secto r Erase comm and is a six bus cycle operation. The sector address is latched on the falling WE input command is latched at the rising edge of WE sector erase starts after the rising edge of WE cycle. The erase oper ation is internal ly controlled; it will automatically time to c omple tion. W hen the b oot block pro­gramming lockout featur e 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:
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 autom ati ca ll y ge nerate the required inter nal 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 t also be used to indicate the end of a program cycle.

Enablin g the l ockout fe ature will allow t he 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 u sa ge a s 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 enabl ed, the da ta in the bo ot block c an no longer be erased or programmed when input levels of
5.5V or less are u sed. Dat a in the m ain mem ory bloc k 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:
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 wil l s how i f pr ogram mi ng the b oot block is locked out. If the data on I/O0 is low, the boot bl oc k c an be programmed; if the data on I/O0 is high, the program lock­out feature has been enabled and the bl ock ca nnot 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 ta king the RES ET entire chip eras e, s ecto r era se or wor d pr ogramm ing oper ­ation. When the RESET the boot block programming lockout feature is again active.
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:
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 c omple ment of t he load ed data on I/O7 . Once the program cycle has been completed, true data is valid on all output s and the next c ycle ma y begin . Duri ng 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.

TOGGLE BIT:
In addition to DATA
polling the AT49BV/LV8192 provides another method for determining the end of a program or erase cycle. Dur ing 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. Examini ng 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 followin g ways: (a) V

CC
power on delay: once VCC has reached the
CC
ms (typical) before pr ogramm ing. (c) Prog ram inhib it: hold ­ing 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, th e address inp uts and con trol inputs (OE
, and WE) may be driven from 0 to 5.5V without
CE adversely affecting the operation of the device. The I/O lines can only be driven from 0 to V
+ 0.6V.
