result in the complement of the loaded data on I/O7. Once
the program cycle has been completed, true data is valid
on all outputs and the next cycle may begin. During a chip
or sector erase operation, an attempt to read the device will
give a “0” on I/O7. Once the program or erase cycle has
completed, true data will be read from the device. DATA
polling may begin at any time during the program cycle.

AT49BV/LV8192(T) provides another method for determin-
ing 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.

ms (typical) before programming. (c) Program inhibit: hold-
ing any one of OE low, CE high or WE high inhibits pro-
gram cycles. (d) Noise filter: pulses of less than 15 ns
(typical) on the WE or CE inputs will not initiate a program
cycle.
INPUT LEVELS: While operating with a 2.7V to 3.6V
power supply, the address inputs and control inputs (OE,
CE, and WE) may be driven from 0 to 5.5V without
adversely affecting the operation of the device. The I/O
lines can only be driven from 0 to V
