Toggle Bit
Optional Chip Erase Mode
In addition to DATA polling, the AT29LV512 provides another method for determining the end of
a program or erase cycle. During a program or erase operation, successive attempts to read
data from the device will result in I/O6 toggling between one and zero. Once the program cycle
has completed, I/O6 will stop toggling and valid data will be read. Examining the toggle bit may
begin at any time during a program cycle.
The entire device can be erased by using a 6-byte software code. Please see Software Chip
Erase application note for details.

*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
