SIGNAL DESCRIPTIONS
Names, for a brief overview of the signals connect-
ed to this device.
Address Inputs (A0-A20). The Address Inputs
select the cells in the memory array to access dur-
ing Bus Read operations. During Bus Write opera-
tions they control the commands sent to the
Command Interface of the internal state machine.
Data Inputs/Outputs (DQ0-DQ7). The Data I/O
outputs the data stored at the selected address
during a Bus Read operation. During Bus Write
operations they represent the commands sent to
the Command Interface of the internal state ma-
chine.
Chip Enable (E). The Chip Enable, E, activates
the memory, allowing Bus Read and Bus Write op-
erations to be performed. When Chip Enable is
High, VIH, all other pins are ignored.
Output Enable (G). The Output Enable, G, con-
trols the Bus Read operation of the memory.
Write Enable (W). The Write Enable, W, controls
the Bus Write operation of the memory’s Com-
mand Interface.
Reset/Block Temporary Unprotect (RP). The
Reset/Block Temporary Unprotect pin can be
used to apply a Hardware Reset to the memory or
to temporarily unprotect all Blocks that have been
protected.
A Hardware Reset is achieved by holding Reset/
Block Temporary Unprotect Low, VIL, for at least
tPLPX. After Reset/Block Temporary Unprotect
goes High, VIH, the memory will be ready for Bus
Read and Bus Write operations after tPHEL or
tRHEL, whichever occurs last. See the Ready/Busy
Temporary Unprotect AC Characteristics for more
details.
Holding RP at VID will temporarily unprotect the
protected Blocks in the memory. Program and
Erase operations on all blocks will be possible.
The transition from VIH to VID must be slower than
tPHPHH.
Ready/Busy Output (RB). The Ready/Busy pin
is an open-drain output that can be used to identify
when the device is performing a Program or Erase
operation. During Program or Erase operations
Ready/Busy is Low, VOL. Ready/Busy is high-im-
pedance during Read mode, Auto Select mode
and Erase Suspend mode.
After a Hardware Reset, Bus Read and Bus Write
operations cannot begin until Ready/Busy be-
comes high-impedance. See Table 13 and Figure
13, Reset/Temporary Unprotect AC Characteris-
tics.
The use of an open-drain output allows the Ready/
Busy pins from several memories to be connected
to a single pull-up resistor. A Low will then indicate
that one, or more, of the memories is busy.
VCC Supply Voltage (5V). VCC
provides
the
power supply for all operations (Read, Program
and Erase).
The Command Interface is disabled when the VCC
Supply Voltage is less than the Lockout Voltage,
VLKO. This prevents Bus Write operations from ac-
cidentally damaging the data during power up,
power down and power surges. If the Program/
Erase Controller is programming or erasing during
this time then the operation aborts and the memo-
ry contents being altered will be invalid.
A 0.1F capacitor should be connected between
the VCC Supply Voltage pin and the VSS Ground
pin to decouple the current surges from the power
supply, see Figure 10, AC Measurement Load Cir-
cuit. The PCB track widths must be sufficient to
carry the currents required during program and
erase operations, ICC3.
VSS Ground. VSS is the reference for all voltage
measurements.
