TOGGLE BIT: 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 opera-
tion, 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 pro-
gram cycle.
OPTIONAL CHIP ERASE MODE: The entire device can be erased by using a 6-byte
software code. Please see Software Chip Erase application note for details.
Absolute Maximum Ratings*
Temperature Under Bias................................ -55°Cto+125°C
*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
device reliability
