TOGGLE BIT:
In addition to DATA polling the
AT49BV/LV8192 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 tog-
gling and valid data will be read. Examining the toggle bit
may begin at any time during a program cycle.
HARDWARE DATA PROTECTION:
Hardware features
protect against inadvertent programs to the
AT49BV/LV8192 in the following ways: (a) V
CC
sense: if
V
CC
is below 1.8V (typical), the program function is inhib-
ited. (b) V
CC
power on delay: once V
CC
has reached the
V
CC
sense level, the device will automatically time out 10
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 (typi-
cal) 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
CC
+ 0.6V.
