Command Definitions

Writing

specific

address

and

data

commands

or

sequences into the command register initiates device

operations. The Command Definitions table defines the

valid register command sequences. Writing incorrect

address and data values or writing them in the improper

sequence resets the device to reading array data.

All addresses are latched on the falling edge of

WE or

CE , whichever happens later. All data is latched on the

rising edge of

WE or CE , whichever happens first. Refer

to

the

appropriate

timing

diagrams

in

the

"AC

Characteristics" section.

Reading Array Data

The device is automatically set to reading array data after

device power-up. No commands are required to retrieve

data. The device is also ready to read array data after

completing an Embedded Program or Embedded Erase

algorithm. After the device accepts an Erase Suspend

command, the device enters the Erase Suspend mode.

The system can read array data using the standard read

timings, except that if it reads at an address within erase-

suspended sectors, the device outputs status data. After

completing

a

programming

operation

in

the

Erase

Suspend mode, the system may once again read array

data with the same exception. See "Erase Suspend/Erase

Resume Commands" for more information on this mode.

The system must issue the reset command to re-enable

the device for reading array data if I/O5 goes high, or while

in the autoselect mode. See the "Reset Command"

section, next.

See also "Requirements for Reading Array Data" in the

"Device Bus Operations" section for more information. The

Read Operations table provides the read parameters, and

Read Operation Timings diagram shows the timing

diagram.

Reset Command

Writing the reset command to the device resets the device

to reading array data. Address bits are don't care for this

command. The reset command may be written between

the sequence cycles in an erase command sequence

before erasing begins. This resets the device to reading

array data. Once erasure begins, however, the device

ignores reset commands until the operation is complete.

The

reset

command

may

be

written

between

the

sequence cycles in a program command sequence before

programming begins. This resets the device to reading

array data (also applies to programming in Erase Suspend

mode). Once programming begins, however, the device

ignores reset commands until the operation is complete.

The

reset

command

may

be

written

between

the

sequence cycles in an autoselect command sequence.

Once in the autoselect mode, the reset command must be

written to return to reading array data (also applies to

autoselect during Erase Suspend).

If I/O5 goes high during a program or erase operation,

writing the reset command returns the device to reading

array data (also applies during Erase Suspend).

Autoselect Command Sequence

The autoselect command sequence allows the host

system to access the manufacturer and devices codes,

and determine whether or not a sector is protected. The

Command Definitions table shows the address and data

requirements. This method is an alternative to that shown

in the Autoselect Codes (High Voltage Method) table,

which is intended for PROM programmers and requires

VID on address bit A9.

The autoselect command sequence is initiated by writing

two unlock cycles, followed by the autoselect command.

The device then enters the autoselect mode, and the

system may read at any address any number of times,

without initiating another command sequence.

A read cycle at address XX00h retrieves the manufacturer

code and another read cycle at XX03h retrieves the

continuation code. A read cycle at address XX01h returns

the device code. A read cycle containing a sector address

(SA) and the address 02h in returns 01h if that sector is

protected, or 00h if it is unprotected. Refer to the Sector

Address tables for valid sector addresses.

The system must write the reset command to exit the

autoselect mode and return to reading array data.

Byte Program Command Sequence

Programming is a four-bus-cycle operation. The program

command sequence is initiated by writing two unlock write

cycles, followed by the program set-up command. The

program address and data are written next, which in turn

initiate the Embedded Program algorithm. The system is

not required to provide further controls or timings. The

device

automatically

provides

internally

generated

program pulses and verify the programmed cell margin.

The Command Definitions table shows the address and

data

requirements

for

the

byte

program

command

sequence.

When the Embedded Program algorithm is complete, the

device then returns to reading array data and addresses

are no longer latched. The system can determine the

status of the program operation by using I/O7 or I/O6. See

"Write Operation Status" for information on these status

bits.

Any commands written to the device during the Embedded

Program Algorithm are ignored. Programming is allowed in

any sequence and across sector boundaries. A bit cannot

be programmed from a "0" back to a "1 ". Attempting to do

so may halt the operation and set I/O5 to "1", or cause the

Data Polling algorithm to indicate the operation was

successful. However, a succeeding read will show that the

data is still "0". Only erase operations can convert a "0" to

a "1".
