... The device contains a user-enabled “boot block” protection feature. Two versions of the feature are available: the AT49F008A/8192A locates the boot block at lowest order addresses (“bottom boot”); the AT49F008AT/8192AT locates it at highest order addresses (“top boot”). To allow for simple in-system reprogrammability, the AT49F008A(T)/8192A(T) does not require high-input voltages for programming. Reading data out of the device is similar to reading from an EPROM ...

... The device is erased by executing the Erase command sequence; the device internally con- trols the erase operation. The memory is divided into four blocks for erase operations. There are two 4K word parameter block sections: the boot block, and the main memory array block. The typical number of program and erase cycles is in excess of 10,000 cycles. ...

... 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 00000H to 03FFFH for the AT49F008A; FC000H to FFFFFH for the AT49F008AT; 00000H to 01FFFH for the AT49F8192A; and 7E000H to 7FFFFH for the AT49F8192AT. ...

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 pro- grammed ...
