... Typical 10,000 Write Cycles Description The AT49BV001A(N)( 2.7-volt-only in-system reprogrammable Flash Memory. Its 1 megabit of memory is organized as 131,072 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times with power dissipation of just 54 mW over the industrial temperature range. ...

... When the device is deselected, the CMOS standby current is less than 50 µA. For the AT49BV001AN(T), pin 1 for the PLCC package and pin 9 for the TSOP package are no con- nect pins. To allow for simple in-system reprogrammability, the AT49BV001A(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 ...

... Device READ: The AT49BV001A(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 Operation on the outputs. The outputs are put in the high impedance state whenever high. This dual-line control gives designers flexibility in preventing bus contention. ...

... AT49BV001A(N), and a read from address location 1C002H will show if programming the boot block is locked out for the AT49BV001A(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 ...

... DATA POLLING: The AT49BV001A(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 ...
