... The device contains a user-enabled “boot block” protection feature. Two versions of the feature are available: the AT49BV008A/8192A locates the boot block at lowest order addresses (“bottom boot”); the AT49BV008AT/8192AT locates it at highest order addresses (“top boot”). To allow for simple in-system reprogrammability, the AT49BV008A(T)/8192A(T) does not require high input voltages for programming. Reading data out of the device is similar to reading from an EPROM ...
