The VPP pin provides data protection and faster programming times. When the V
below 0.7V, the program and erase functions are inhibited. When V
mal program and erase operations can be performed. With V
word program command) operation is accelerated.
A six-byte command (Enter Single Pulse Program Mode) to remove the requirement of entering
the three-byte program sequence is offered to further improve programming time. After entering
the six-byte code, only single pulses on the write control lines are required for writing into the
device. This mode (Single Pulse Word Program) is exited by powering down the device, by tak-
ing the RESET pin to GND or by a high-to-low transition on the V
Suspend/Resume, Program Suspend/Resume and Read Reset commands will not work while in
this mode; if entered they will result in data being programmed into the device. It is not recom-
mended that the six-byte code reside in the software of the final product but only exist in external
programming code.
