... 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” ...

... Reading data out of the device is similar to reading from an EPROM. Repro- gramming the AT49F080 is performed by erasing the entire 8 megabits of memory and then programming on a byte-by- byte basis. The typical byte programming time is a fast 10 s ...

... The address range of the AT49F080 boot block is 00000H to 03FFFH while the address range of the AT49F080T boot block is FC000H to FFFFFH. 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. ...
