SUMMARY DESCRIPTION
The M29KW032E LightFlash™ is a 32 Mbit (2Mb
x16) non-volatile memory that can be read, erased
and reprogrammed. Read operations can be performed using a single low voltage (2.7 to 3.6V)
supply. Program and Erase operations require an
additional VPP (11.4 to 12.6) power supply. On
power-up the memory defaults to its Read mode
where it can be read in the same way as a ROM or
EPROM.
The memory is divided into 16 uniform blocks that
can be erased independently so it is possible to
preserve valid data while old data is erased (see
Figures 2, Block Addresses). Program and Erase
commands are written to the Command Interface
of the memory. An on-chip Program/Erase Controller (P/E.C.) simplifies the process of programming or erasing the memory by taking care of all of
the special operations that are required to update
the memory contents.

The M29KW032E LightFlash™ features a new
command, Multiple Word Program, used to program large streams of data. It greatly reduces the
total programming time when a large number of
Words are written to the memory at any one time.
Using this command the entire memory can be
programmed in 2s, compared to 9s using the standard Word Program.
The end of a program or erase operation can be
detected and any error conditions identified. The
command set required to control the memory is
consistent with JEDEC standards.
Chip Enable, Output Enable and Write Enable signals control the bus operation of the memory.
They allow simple connection to most microprocessors, often without additional logic.
The memory is offered in TSOP48 (12 x 20mm)
and TFBGA48 (6 x 9mm, 0.8mm pitch) packages.
The memory is supplied with all the bits erased
(set to ’1’).

SIGNAL DESCRIPTIONS
See Figure 2, Logic Diagram, and Table 1, Signal
Names, for a brief overview of the signals connected to this device.
Address Inputs (A0-A20). The Address Inputs
select the cells in the memory array to access during Bus Read operations. During Bus Write operations they control the commands sent to the
Command Interface of the Program/Erase Controller.
Data Inputs/Outputs (DQ0-DQ7). The Data Inputs/Outputs 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 Program/Erase Controller.
Data Inputs/Outputs (DQ8-DQ15). The Data Inputs/Outputs output the data stored at the selected
address during a Bus Read operation. During Bus
Write operations the Command Register does not
use these bits. When reading the Status Register
these bits should be ignored.
Chip Enable (E). The Chip Enable, E, activates
the memory, allowing Bus Read and Bus Write operations to be performed. When Chip Enable is
High, V IH, all other pins are ignored.
Output Enable (G). The Output Enable, G, controls the Bus Read operation of the memory.
Write Enable (W). The Write Enable, W, controls
the Bus Write operation of the memory’s Command Interface.
Reset (RP). The Reset pin can be used to apply
a Hardware Reset to the memory.
A Hardware Reset is achieved by holding Reset
Low, V IL, for at least tPLPX. After Reset goes High,
VIH, the memory will be ready for Bus Read and
Bus Write operations after tPHEL or t RHEL, whichever occurs last. See the Ready/Busy Output section, Table 16 and Figure 13, Reset AC
Characteristics for more details.
Ready/Busy Output (RB). The Ready/Busy pin
is an open-drain output that can be used to identify
when the memory array can be read. Ready/Busy
is high-impedance during Read mode and Auto
Select mode. After a Hardware Reset, Bus Read
and Bus Write operations cannot begin until
Ready/Busy becomes high-impedance. See Table
16 and Figure 13, Reset AC Characteristics.
During Program or Erase operations Ready/Busy
is Low, VOL. Ready/Busy will remain Low during
Read/Reset commands or Hardware Resets until
the memory is ready to enter Read mode.
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. The VCC Supply Voltage
supplies the power for Read operations.
The Command Interface is disabled when the V CC
Supply Voltage is less than the Lockout Voltage,
VLKO. This prevents Bus Write operations from accidentally 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 memory contents being altered will be invalid.
A 0.1µF capacitor should be connected between
the V CC Supply Voltage pin and the VSS Ground
pin to decouple the current surges from the power
supply. The PCB track widths must be sufficient to
carry the currents required during program and
erase operations, ICC3.
V PP Program Supply Voltage. VPP is both a
power supply and Write Protect pin. The two functions are selected by the voltage range applied to
the pin. The Supply Voltage VCC must be applied
before the Program Supply Voltage VPP.
If VPP is in the range 11.4V to 12.6V it acts as a
power supply pin for program and erase operations. VPP must be stable until the Program/Erase
algorithm is completed.
If VPP is kept in a low voltage range (0V to 3.6V)
VPP is seen as a Write Protect pin. In this case a
voltage lower than VHH gives an absolute protection against program or erase, while VPP in the
range of V HH enables these functions (see Table
12, DC Characteristics for the relevant values).
Note that VPP must not be left floating or unconnected as the device may become unreliable.
Vss Ground. The VSS Ground is the reference
for all voltage measurements.

BUS OPERATIONS
There are six standard bus operations that control
the device. These are Bus Read, Bus Write, Output Disable, Standby, Automatic Standby and
Electronic Signature. See Tables 3, Bus Operations, for a summary. Typically glitches of less
than 5ns on Chip Enable or Write Enable are ignored by the memory and do not affect bus operations.
Bus Read. Bus Read operations read from the
memory cells, or specific registers in the Command Interface. A valid Bus Read operation involves setting the desired address on the Address
Inputs, applying a Low signal, V IL, to Chip Enable
and Output Enable and keeping Write Enable
High, VIH. The Data Inputs/Outputs will output the
value, see Figure 10, Read Mode AC Waveforms,
and Table 13, Read AC Characteristics, for details
of when the output becomes valid.
Bus Write. Bus Write operations write to the
Command Interface. A valid Bus Write operation
begins by setting the desired address on the Address Inputs. The Address Inputs are latched by
the Command Interface on the falling edge of Chip
Enable or Write Enable, whichever occurs last.
The Data Inputs/Outputs are latched by the Command Interface on the rising edge of Chip Enable
or Write Enable, whichever occurs first. Output Enable must remain High, VIH, during the whole Bus
Write operation. See Figures 11 and 12, Write AC
Waveforms, and Tables 14 and 15, Write AC
Characteristics, for details of the timing requirements.
Output Disable. The Data Inputs/Outputs are in
the high impedance state when Output Enable is
High, V IH.
Standby. When Chip Enable is High, VIH, the
memory enters Standby mode and the Data Inputs/Outputs pins are placed in the high-impedance state. To reduce the Supply Current to the
Standby Supply Current, ICC2, Chip Enable should
be held within VCC ± 0.2V. For the Standby current
level see Table 12, DC Characteristics.
During program or erase operations the memory
will continue to use the Program/Erase Supply
Current, ICC3, for Program or Erase operations until the operation completes.
Automatic Standby. If CMOS levels (VCC ± 0.2V)
are used to drive the bus and the bus is inactive for
150ns or more the memory enters Automatic
Standby where the internal Supply Current is reduced to the Standby Supply Current, ICC2. The
Data Inputs/Outputs will still output data if a Bus
Read operation is in progress.
Electronic Signature. The memory has two
codes, the manufacturer code and the device
code, that can be read to identify the memory.
These codes can be read by applying the signals
listed in Tables 3, Bus Operations.

COMMAND INTERFACE
All Bus Write operations to the memory are interpreted by the Command Interface. Commands
consist of one or more sequential Bus Write operations. Failure to observe a valid sequence of Bus
Write operations will result in the memory returning to Read mode. The long command sequences
are imposed to maximize data security.
Refer to Tables 4 and 5, for a summary of the commands.
Read/Reset Command.
The Read/Reset command returns the memory to
its Read mode where it behaves like a ROM or
EPROM, unless otherwise stated. It also resets
the errors in the Status Register. Either one or
three Bus Write operations can be used to issue
the Read/Reset command.
The Read/Reset Command can be issued, between Bus Write cycles before the start of a program or erase operation, to return the device to
read mode. Once the program or erase operation
has started the Read/Reset command is no longer
accepted. The Read/Reset command is executed
regardless of the value of VPP (VIL, VIH or VHH).
Auto Select Command.
The Auto Select command is used to read the
Manufacturer Code and the Device Code. Three
consecutive Bus Write operations are required to
issue the Auto Select command. Once the Auto
Select command is issued the memory remains in
Auto Select mode until a Read/Reset command is
issued, all other commands are ignored. The Auto
Select command is executed regardless of the value of VPP (VIL, VIH or VHH).
From the Auto Select mode the Manufacturer
Code can be read using a Bus Read operation
with A0 = V IL and A1 = VIL. The other address bits
may be set to either VIL or VIH.
The Device Code can be read using a Bus Read
operation with A0 = VIH and A1 = VIL. The other
address bits may be set to either VIL or VIH.
Word Program Command.
The Word Program command can be used to program a Word to the memory array. V PP must be
set to V HH during Word Program. If VPP is set to either VIL or VIH the command will be ignored, the
data will remain unchanged and the device will revert to Read/Reset mode. The command requires
four Bus Write operations, the final write operation
latches the address and data in the internal state
machine and starts the Program/Erase Controller.
During the program operation the memory will ignore all commands. It is not possible to issue any
command to abort or pause the operation. Typical
program times are given in Table 6. Bus Read operations during the program operation will output
the Status Register on the Data Inputs/Outputs.
See the section on the Status Register for more
details.
After the program operation has completed the
memory will return to the Read mode, unless an
error has occurred. When an error occurs the
memory will continue to output the Status Register. A Read/Reset command must be issued to reset the error condition and return to Read mode.
Note that the Program command cannot change a
bit set at ’0’ back to ’1’. One of the Erase Commands must be used to set all the bits in a block or
in the whole memory from ’0’ to ’1’.
Multiple Word Program Command
The Multiple Word Program command can be
used to program large streams of data. It greatly
reduces the total programming time when a large
number of Words are written to the memory at any
one time. V PP must be set to VHH during Multiple
Word Program. If VPP is set to either VIL or VIH the
command will be ignored, the data will remain unchanged and the device will revert to Read/Reset
mode.
It has four phases: the Setup Phase to initiate the
command, the Program Phase to program the
data to the memory, the Verify Phase to check that
the data has been correctly programmed and reprogram if necessary and the Exit Phase.
Setup Phase. The Multiple Word Program command requires three Bus Write operations to initiate the command (refer to Table 5, Multiple Word
Program Command and Figure 5, Multiple Word
Program Flowchart). The Status Register Toggle
bit (DQ6) should be checked to verify that the operation has started and the Multiple Word Program
bit (DQ0) checked to verify that the P/E.C. is ready
for the first Word.
Program Phase. The Program Phase requires
n+1 cycles, where n is the number of Words, to execute the programming phase (refer to Table 5,
Multiple Word Program Command and Figure 5,
Multiple Word Program Flowchart).
Three successive steps are required to issue and
execute the Program Phase of the command.
1. The fourth Bus Write operation of the command
latches the Start Address and the first Word to
be programmed. The Status Register Multiple
Word Program bit (DQ0) should be read to
check that the P/E.C. is ready for the next Word.
2. Each subsequent Word to be programmed is
latched with a new Bus Write operation. The
address can remain the Start Address, be
incremented or be any address in the same
block, as the device automatically increments
the address with each sucssesive Bus Write
9/30
M29KW032E
cycle. If the command is used to program in
more than one block then the address must
remain in the starting block as any address that
is not in the same block as the Start Address
terminates the Program operation. The Status
Register Multiple Word Program bit (DQ0) must
be read between each Bus Write cycle to check
that the P/E.C. is ready for the next Word.
3. Finally, after all Words have been programmed,
write one Bus Write operation to any address
outside the block containing the Start Address,
to terminate the programming phase.
The memory is now set to enter the Verify Phase.
Verify Phase. The Verify Phase is similar to the
Program Phase in that all Words must be resent to
the memory for them to be checked against the
programmed data. If the check fails the P/E.C will
try to reprogram the correct data. The P/E.C will
remain busy until the correct data has been successfully programmed. The Verify Phase is mandatory. If the Verify Phase is not executed the
programmed data cannot be guaranteed.
Three successive steps are required to execute
the Verify Phase of the command.
1. Use one Bus Write operation to latch the Start
Address and the first Word, to be verified. The
Status Register Multiple Word Program bit
(DQ0) should be read to check that the P/E.C. is
ready for the next Word.
2. Each subsequent Word to be verified is latched
with a new Bus Write operation. If any address
that is not in the same block as the Start
Address is given, the Verify operation
terminates. The Status Register Multiple Word
Program (DQ0) must be read to check that the
P/E.C. is ready for the next Word.
3. Finally, after all Words have been verified, write
one Bus Write operation to any address outside
the block containing the Start Address, to
terminate the Verify Phase.
Exit Phase . Read the Status Register to verify
that DQ6 has stopped toggling. If the Verify Phase
is successfully completed the memory returns to
the Read mode. If the P/E.C. fails to reprogram a
given location, the Verify Phase will terminate and
Error bit DQ5 will be set in the Status Register. If
the error is due to a V PP failure DQ4 will also be
set. If the operation fails a Read/Reset command
must be issued to return the device to Read mode.
It is not possible to issue any command to abort or
pause the operation. Typical program times are
given in Table 6. Bus Read operations during the
program operation will output the Status Register
on the Data Inputs/Outputs. See the section on the
Status Register for more details.
10/30
Note that the Multiple Word Program command
cannot change a bit set at ’0’ back to ’1’. One of the
Erase Commands must be used to set all the bits
in a block or in the whole memory from ’0’ to ’1’.
Block Erase Command.
The Block Erase command can be used to erase
a block. It sets all of the bits in the block to ’1’. All
previous data in the block is lost.
VPP must be set to V HH during Block Erase. If VPP
is set to either V IL or V IH the command will be ignored, the data will remain unchanged and the device will revert to Read/Reset mode.
Six Bus Write operations are required to select the
block . The Block Erase operation starts the Program/Erase Controller after the last Bus Write operation. The Status Register can be read after the
sixth Bus Write operation. See the Status Register
for details on how to identify if the Program/Erase
Controller has started the Block Erase operation.
During the Block Erase operation the memory will
ignore all commands. Typical block erase times
are given in Table 6. All Bus Read operations during the Block Erase operation will output the Status Register on the Data Inputs/Outputs. See the
section on the Status Register for more details.
After the Block Erase operation has completed the
memory will return to the Read Mode, unless an
error has occurred. When an error occurs the
memory will continue to output the Status Register. A Read/Reset command must be issued to reset the error condition and return to Read mode.
Chip Erase Command.
The Chip Erase command can be used to erase
the entire memory. It sets all of the bits in the memory to ’1’. All previous data in the memory is lost.
VPP must be set to V HH during Chip Erase. If VPP
is set to either V IL or V IH the command will be ignored, the data will remain unchanged and the device will revert to Read/Reset mode. Six Bus Write
operations are required to issue the Chip Erase
Command and start the Program/Erase Controller.
During the erase operation the memory will ignore
all commands. It is not possible to issue any command to abort the operation. Typical chip erase
times are given in Table 6. All Bus Read operations during the Chip Erase operation will output
the Status Register on the Data Inputs/Outputs.
See the section on the Status Register for more
details.
After the Chip Erase operation has completed the
memory will return to the Read Mode, unless an
error has occurred. When an error occurs the
memory will continue to output the Status Register. A Read/Reset command must be issued to reset the error condition and return to Read Mode.

STATUS REGISTER
Bus Read operations from any address always
read the Status Register during Program and
Erase operations. The bits in the Status Register
are summarized in Table 8, Status Register Bits.
Data Polling Bit (DQ7). The Data Polling Bit can
be used to identify whether the Program/Erase
Controller has successfully completed its operation. The Data Polling Bit is output on DQ7 when
the Status Register is read.
During a Word Program operation the Data Polling
Bit outputs the complement of the bit being programmed to DQ7. After successful completion of
the Word Program operation the memory returns
to Read mode and Bus Read operations from the
address just programmed output DQ7, not its complement. The Data Polling Bit is not available during a Multiple Word Program operation.
During Erase operations the Data Polling Bit outputs ’0’, the complement of the erased state of
DQ7. After successful completion of the Erase operation the memory returns to Read Mode.
Figure 6, Data Polling Flowchart, gives an example of how to use the Data Polling Bit. A Valid Address is the address being programmed or an
address within the block being erased.
Toggle Bit (DQ6). The Toggle Bit can be used to
identify whether the Program/Erase Controller has
successfully completed its operation. The Toggle
Bit is output on DQ6 when the Status Register is
read.
During Program and Erase operations the Toggle
Bit changes from ’0’ to ’1’ to ’0’, etc., with successive Bus Read operations at any address. After
successful completion of the operation the memory returns to Read mode.
Figure 7, Data Toggle Flowchart, gives an example of how to use the Data Toggle Bit.
Error Bit (DQ5). The Error Bit can be used to
identify errors detected by the Program/Erase
Controller. The Error Bit is set to ’1’ when a Program, Block Erase or Chip Erase operation fails to
write the correct data to the memory. If the Error
Bit is set a Read/Reset command must be issued
before other commands are issued. The Error bit
is output on DQ5 when the Status Register is read.
Note that the Program command cannot change a
bit set to ’0’ back to ’1’ and attempting to do so will
set DQ5 to ‘1’. A Bus Read operation to that address will show the bit is still ‘0’. One of the Erase
commands must be used to set all the bits in a
block or in the whole memory from ’0’ to ’1’.
VPP Status Bit (DQ4). The VPP Status Bit can be
used to identify if any Program or Erase operation
has failed due to a VPP error. If VPP falls below V HH
during any Program or Erase operation, the operation aborts and DQ4 is set to ‘1’. If VPP remains at
VHH throughout the Program or Erase operation,
the operation completes and DQ4 is set to ‘0’.
Erase Timer Bit (DQ3). The Erase Timer Bit can
be used to identify the start of Program/Erase
Controller operation during a Block Erase command. Once the Program/Erase Controller starts
erasing the Erase Timer Bit is set to ’1’. The Erase
Timer Bit is output on DQ3 when the Status Register is read.
Alternative Toggle Bit (DQ2). The Alternative
Toggle Bit can be used to monitor the Program/
Erase controller during Block and Chip Erase operations. The Alternative Toggle Bit is output on
DQ2 when the Status Register is read.
During Erase operations the Toggle Bit changes
from ’0’ to ’1’ to ’0’, etc., with successive Bus Read
operations to any address. Once the operation
completes the memory returns to Read mode.
If an Erase operation fails and the Error Bit is set,
the Alternative Toggle Bit will continue to toggle
with successive Bus Read operations to any address. The Alternative Toggle Bit does not change
if the addressed block has erased correctly.
Multiple Word Program Bit (DQ0). The Multiple
Word Program Bit can be used to indicate whether
the Program/Erase Controller is active or inactive
during Multiple Word Program. When the Program/Erase Controller has written one Word and is
ready to accept the next Word, the bit is set to ‘0’.
Status Register Bit DQ1 is reserved.
