When the device is deselected, the CMOS standby current is less than 50 µA. To allow for
simple in-system reprogrammability, the AT49BV040A does not require high input voltages for
programming. Three-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 AT49BV040A is
performed by erasing a block of data and then programming 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 controls the erase operations. There are two 8K byte parameter block sections, eight 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 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 permanently protected from being
reprogrammed.

AT49BV040A
Device
Operation
READ: The AT49BV040A 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 command sequences.
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 logical “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 operation 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 - 8, 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 eight
main memory blocks. The 8K-byte parameter block sections and the eight 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
automatically time to completion.
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. 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 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
3
3358A–FLASH–6/03
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.
Once the feature is enabled, the data in the boot block can no longer be erased or programmed. 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 activated and the block cannot be programmed. The software product identification code should be used to return to standard operation.
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 AT49BV040A 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. DATA polling may begin at any time during
the program cycle.
TOGGLE BIT: In addition to DATA polling the AT49BV040A 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 AT49BV040A 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.
