MONITORING POWER SUPPLY VOLTAGE: VPP is not used for power supply pin.
With VPP VPPLK, block erase, full chip erase, (page buffer) program or OTP program
cannot be executed and should not be attempted.
Applying 12V±0.3V to VPP provides fast erasing or fast programming mode. In this
mode, VPP is power supply pin. Applying 12V±0.3V to VPP during erase/program can
only be done for a maximum of 1000 cycles on each block. VPP may be connected to
12V±0.3V for a total of 80 hours maximum. Use of this pin at 12V beyond these limits
may reduce block cycling capability or cause permanent damage.
DEVICE POWER SUPPLY (see specifications): With VCC VLKO, all write attempts to
the flash memory are inhibited. Device operations at invalid VCC voltage (see DC
Characteristics) produce spurious results and should not be attempted.
INPUT/OUTPUT POWER SUPPLY (see specifications): Power supply for all input/
output pins.
GROUND: Do not float any ground pins.
NO CONNECT: Lead is not internally connected; it may be driven or floated.
