Write protect is an input that gives an additional hardware protection for each block. When Write Protect
is
When Write Protect is
locked or unlocked.
The Reset input provides a hardware reset of the memory. When reset is 0.4V, the memory is in reset
mode: the outputs are high impedant and the current consumption is minimized. After Reset all blocks
are in Locked state. When Reset is (vddq - 0.4V), the device is in normal operation. Exiting reset mode
the device enters read array mode, but a negative transition of Chip Enable or a change of the address
is required to ensure valid data outputs.
Vdd provides the power supply to the internal core of the flash memory device. It is the main power sup-
ply for all operations (Read, Program and Erase)
Vddq provides the power supply to the I/O pins and enables all Outputs to be powered independently
from Vddf. Vddq can be tied to Vddf or can use separate supply.
0.4V the Lock-Down is enabled and the protection status of the flash blocks cannot be changed.
(vddq - 0.4V), the Lock-Down is disabled and the flash memory blocks can be
