... CMOS standby current is less than 100 A. The device contains a user-enabled “boot block” protection feature. Two versions of the feature are available: the AT49F080 locates the boot block at lowest order addresses (“bottom boot”); the AT49F080T locates it at highest order addresses (“top boot” ...

... To allow for simple in-system reprogrammability, the AT49F080(T) does not require high input voltages for pro- gramming. 5-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. Repro- gramming the AT49F080(T) is performed by erasing the entire 8 megabits of memory and then programming on a byte-by-byte basis ...

... AT49F080, and a read from address location F3002H will show if programming the boot block is locked out for the AT49F080T. 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 ...
