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 pro-
grammer to identify the correct programming algorithm for
the Atmel product. In addition, users may wish to use the
software product identification mode to identify the part (i.e.
using the device code), and have the system software use
the appropriate sector size for program operations. In this
manner, the user can have a common board design for
256K to 4-megabit densities and, with each density’s sector
size in a memory map, have the system software apply the
appropriate sector size.
For details, see Operating Modes (for hardware operation)
or Software Product Identification. The manufacturer and
device code is the same for both methods of identification.
DATA POLLING:
The AT29BV010A features DATA poll-
ing to indicate the end of a program cycle. During a pro-
gram 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
AT29BV010A 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 tog-
gling and valid data will be read. Examining the toggle bit
may begin at any time during a program cycle.
OPTIONAL CHIP ERASE MODES:
may be erased by using a 6-byte software code. Please
see Software Chip Erase application note for details.

BOOT BLOCK PROGRAMMING LOCKOUT:
AT29BV010A has two designated memory blocks that
have a programming lockout feature. This feature prevents
programming of data in the designated block once the fea-
ture has been enabled. Each of these blocks consists of 8K
bytes; the programming lockout feature can be set inde-
pendently for either block. While the lockout feature does
not have to be activated, it can be activated for either or
both blocks.
These two 8K memory sections are referred to as boot
blocks. Secure code which will bring up a system can be
contained in a boot block. The AT29BV010A blocks are
located in the first 8K bytes of memory and the last 8K
bytes of memory. The boot block programming lockout fea-
ture can therefore support systems that boot from the lower
addresses of memory or the higher addresses. Once the
programming lockout feature has been activated, the data
in that block can no longer be erased or programmed; data
in other memory locations can still be changed through the
regular programming methods. To activate the lockout fea-
ture, a series of seven program commands to specific
addresses with specific data must be performed. Please
see Boot Block Lockout Feature Enable Algorithm.
If the boot block lockout feature has been activated on
either block, the chip erase function will be disabled.
BOOT BLOCK LOCKOUT DETECTION:
method is available to determine whether programming of
either boot block section is locked out. See Software Prod-
uct Identification Entry and Exit sections. When the device
is in the software product identification mode, a read from
location 00002H will show if programming the lower
address boot block is locked out while reading location
1FFF2H will do so for the upper boot block. If the data is
FE, the corresponding block can be programmed; if the
data is FF, the program lockout feature has been activated
and the corresponding block cannot be programmed. The
software product identification exit mode should be used to
return to standard operation.
