SUMMARY DESCRIPTION
The M58LW064D is a 64 Mbit (8Mb x 8 or 4Mb
x16) non-volatile memory that can be read, erased
and reprogrammed. These operations can be performed using a single low voltage (2.7V to 3.6V)
core supply.
The memory is divided into 64 blocks of 1Mbit that
can be erased independently so it is possible to
preserve valid data while old data is erased. Program and Erase commands are written to the
Command Interface of the memory. An on-chip
Program/Erase Controller 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 end of
a Program or Erase operation can be detected and
any error conditions identified in the Status Register. The command set required to control the
memory is consistent with JEDEC standards.
The Write Buffer allows the microprocessor to program from 1 to 16 Words in parallel, both speeding
up the programming and freeing up the microprocessor to perform other work. A Word Program
command is available to program a single word.
Erase can be suspended in order to perform either
Read or Program in any other block and then resumed. Program can be suspended to Read data
in any other block and then resumed. Each block
can be programmed and erased over 100,000 cycles.
The M58LW064D has several security features to
increase data protection.
■
Block Protection, where each block can be
individually protected against program or
erase operations. All blocks are protected
during power-up. The protection of the blocks
is non-volatile; after power-up the protection
status of each block is restored to the state
when power was last removed.
Program Erase Enable input VPEN, program or
erase operations are not possible when the
Program Erase Enable input VPEN is low.
■
128 bit Protection Register, divided into two 64
bit segments: the first contains a unique
device number written by ST, the second is
user programmable. The user programmable
segment can be protected.
The Reset/Power-Down pin is used to apply a
Hardware Reset to the enabled memory and to set
the device in power-down mode.
The device features an Auto Low Power mode. If
the bus becomes inactive during read operations,
the device automatically enters Auto Low Power
mode. In this mode the power consumption is reduced to the Auto Low Power supply current.
The STS signal is an open drain output that can be
used to identify the Program/Erase Controller status. It can be configured in two modes: Ready/
Busy mode where a static signal indicates the status of the P/E.C, and Status mode where a pulsing
signal indicates the end of a Program or Block
Erase operation. In Status mode it can be used as
a system interrupt signal, useful for saving CPU
time.
The memory is available in TSOP56 (14 x 20 mm)
and TBGA64 (10x13mm, 1mm pitch) packages.
In addition to the standard version, the packages
are also available in Lead-free version, in compliance with JEDEC Std J-STD-020B, the ST ECOPACK 7191395 Specification, and the RoHS
(Restriction of Hazardous Substances) directive.
All packages are compliant with Lead-free soldering processes.

SIGNAL DESCRIPTIONS
See Figure 2., Logic Diagram, and Table 1., Signal
Names, for a brief overview of the signals connected to this device.
Address Input (A0). The A0 address input is
used to select the higher or lower Byte in X8 mode.
It is not used in X16 mode (where A1 is the Lowest
Significant bit).
Address Inputs (A1-A22). The A1-A22 Address
Inputs are used to select the cells to access in the
memory array during Bus Read operations either
to read or to program data. During Bus Write operations they control the commands sent to the
Command Interface of the internal state machine.
The device must be enabled (refer to Table 2., Device Enable) when selecting the addresses. The
address inputs are latched on the rising edge of
Write Enable or on the first edge of Chip Enables
E0, E1 or E2 that disable the device, whichever
occurs first.
Data Inputs/Outputs (DQ0-DQ15). The Data Inputs/Outputs output the data stored at the selected
address during a Bus Read operation, or are used
to input the data during a program operation. During Bus Write operations they represent the commands sent to the Command Interface of the
internal state machine. When used to input data or
Write commands they are latched on the rising
edge of Write Enable or the first edge of Chip Enables E0, E1 or E2 that disable the device, whichever occurs first.
When the device is enabled and Output Enable is
low, VIL (refer to Table 2., Device Enable), the data
bus outputs data from the memory array, the Electronic Signature, the Block Protection status, the
CFI Information or the contents of the Status Register. The data bus is high impedance when the
device is deselected, Output Enable is high, VIH, or
the Reset/Power-Down signal is low, VIL. When
the Program/Erase Controller is active the Ready/
Busy status is given on DQ7.
Chip Enables (E0, E1, E2). The Chip Enable inputs E0, E1 and E2 activate the memory control
logic, input buffers, decoders and sense amplifiers. The device is selected at the first edge of Chip
Enables E0, E1 or E2 that enable the device and
deselected at the first edge of Chip Enables E0,
E1 or E2 that disable the device. Refer to Table 2.,
Device Enable for more details.
When the Chip Enable inputs deselect the memory, power consumption is reduced to the Standby
level, IDD1.
Output Enable (G). The Output Enable, G, gates
the outputs through the data output buffers during
a read operation. When Output Enable, G, is at VIH
the outputs are high impedance.
10/50
Write Enable (W). The Write Enable input, W,
controls writing to the Command Interface, Input
Address and Data latches. Both addresses and
data can be latched on the rising edge of Write Enable.
Reset/Power-Down (RP). The
Reset/PowerDown pin can be used to apply a Hardware Reset
to the memory.
A Hardware Reset is achieved by holding Reset/
Power-Down Low, VIL, for at least tPLPH. When
Reset/Power-Down is Low, VIL, the Status Register information is cleared and the power consumption is reduced to power-down level. The device is
deselected and outputs are high impedance. If Reset/Power-Down goes low, VIL,during a Block
Erase, a Write to Buffer and Program or a Block
Protect/Unprotect the operation is aborted and the
data may be corrupted. In this case the STS pin
stays low, VIL, for a maximum timing of tPLPH + tPHBH, until the completion of the Reset/Power-Down
pulse.
After Reset/Power-Down goes High, VIH, the
memory will be ready for Bus Read and Bus Write
operations after tPHQV. Note that STS does not fall
during a reset, see Ready/Busy Output section.
In an application, it is recommended to associate
Reset/Power-Down pin, RP, with the reset signal
of the microprocessor. Otherwise, if a reset operation occurs while the memory is performing an
Erase or Program operation, the memory may output the Status Register information instead of being initialized to the default Asynchronous
Random Read.
Byte/Word Organization Select (BYTE). The
Byte/Word Organization Select pin is used to
switch between the x8 and x16 bus widths of the
memory. When Byte/Word Organization Select is
Low, VIL, the memory is in x8 mode, when it is
High, VIH, the memory is in x16 mode.
Status/(Ready/Busy) (STS). The STS signal is
an open drain output that can be used to identify
the Program/Erase Controller status. It can be
configured in two modes:
■
Ready/Busy - the pin is Low, VOL, during
Program and Erase operations and high
impedance when the memory is ready for any
Read, Program or Erase operation.
■
Status - the pin gives a pulsing signal to
indicate the end of a Program or Block Erase
operation.
After power-up or reset the STS pin is configured
in Ready/Busy mode. The pin can be configured
for Status mode using the Configure STS command.
M58LW064D
When the Program/Erase Controller is idle, or suspended, STS can float High through a pull-up resistor. The use of an open-drain output allows the
STS pins from several memories to be connected
to a single pull-up resistor (a Low will indicate that
one, or more, of the memories is busy).
STS is not Low during a reset unless the reset was
applied when the Program/Erase controller was
active
Program/Erase Enable (VPEN). The Program/
Erase Enable input, VPEN, is used to protect all
blocks, preventing Program and Erase operations
from affecting their data.
Program/Erase Enable must be kept High during
all Program/Erase Controller operations, otherwise the operations is not guaranteed to succeed
and data may become corrupt.
VDD Supply Voltage. VDD provides the power
supply to the internal core of the memory device.
It is the main power supply for all operations
(Read, Program and Erase).
VDDQ Supply Voltage. VDDQ provides the power
supply to the I/O pins and enables all Outputs to
be powered independently from VDD. VDDQ can be
tied to VDD or can use a separate supply.
It is recommended to power-up and power-down
VDD and VDDQ together to avoid any condition that
would result in data corruption.
VSS Ground. Ground, VSS, is the reference for
the core power supply. It must be connected to the
system ground.
VSSQ Ground. VSSQ ground is the reference for
the input/output circuitry driven by VDDQ. VSSQ
must be connected to VSS.
Note: Each device in a system should have
VDD and VDDQ decoupled with a 0.1µF ceramic
capacitor close to the pin (high frequency, inherently low inductance capacitors should be
as close as possible to the package). See Figure 8., AC Measurement Load Circuit.

BUS OPERATIONS
There are five standard bus operations that control
the device. These are Bus Read, Bus Write, Output Disable, Power-Down and Standby. See Table
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 Write operations.
Bus Read. Bus Read operations are used to output the contents of the Memory Array, the Electronic Signature, the Status Register, the Common
Flash Interface and the Block Protection Status.
A valid bus operation involves setting the desired
address on the Address inputs, enabling the device (refer to Table 2., Device Enable), applying a
Low signal, VIL, to Output Enable and keeping
Write Enable High, VIH. The data read depends on
the previous command written to the memory (see
Command Interface section).
See Figures 9 and 10 Read AC Waveforms, and
Tables 15 and 16 Read AC Characteristics, for details of when the output becomes valid.
Bus Write. Bus Write operations write Commands to the memory or latch addresses and input
data to be programmed.
A valid Bus Write operation begins by setting the
desired address on the Address Inputs and enabling the device (refer to Chip Enable section).
The Address Inputs are latched by the Command
Interface on the rising edge of Write Enable or the
first edge of E0, E1 or E2 that disables the device
(refer to Table 2., Device Enable).
The Data Input/Outputs are latched by the Command Interface on the rising edge of Write Enable
or the first edge of E0, E1 or E2 that disable the device whichever occurs first. Output Enable must
remain High, VIH, during the Bus Write operation.
See Figures 11 and 12, Write AC Waveforms, and
Tables 17 and 18, Write and Chip Enable Controlled Write AC Characteristics, for details of the
timing requirements.
Output Disable. The Data Inputs/Outputs are
high impedance when the Output Enable is at VIH.
Power-Down. The memory is in Power-Down
mode when Reset/Power-Down, RP, is Low. The
power consumption is reduced to the Power-Down
level, IDD2, and the outputs are high impedance,
independent of Chip Enable, Output Enable or
Write Enable.
Standby. Standby disables most of the internal
circuitry, allowing a substantial reduction of the
current consumption. The memory is in standby
when Chip Enable is at VIH. The power consumption is reduced to the standby level IDD1 and the
outputs are set to high impedance, independently
from the Output Enable or Write Enable inputs.
If Chip Enable switches to VIH during a program or
erase operation, the device enters Standby mode
when finished.

M58LW064D
READ MODES
Read operations in the M58LW064D are asynchronous. The device outputs the data corresponding to the address latched, that is the
memory array, Status Register, Common Flash Interface, Electronic Signature or Block Protection
Status depending on the command issued.
During read operations, if the bus is inactive for a
time equivalent to tAVQV, the device automatically
enters Auto Low Power mode. In this mode the internal supply current is reduced to the Auto Low
Power supply current, IDD5. The Data Inputs/Outputs will still output data if a Bus Read operation is
in progress.
Read operations can be performed in two different
ways, Random Read (where each Bus Read operation accesses a different Page) and Page Read.
In Page Read mode a Page of data is internally
read and stored in a Page Buffer. Each memory
page is a 4 Words or 8 Bytes and has the same
A3-A22. In x8 mode only A0, A1 and A2 may
change, in x16 mode only A1 and A2 may change.
The first read operation within the Page has the
normal access time (tAVQV), subsequent reads
within the same Page have much shorter access
times (tAVQV1). If the Page changes then the normal, longer timings apply again.
See Figure 10., Page Read AC Waveforms, and
Table 16., Page Read AC Characteristics, for details on when the outputs become valid.
13/50
M58LW064D
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. The Commands are summarized in Table
4., Commands. Refer to Table 4. in conjunction
with the text descriptions below.
After power-up or a Reset operation the memory
enters Read mode.
Read Memory Array Command. The Read Memory Array command is used to return the memory
to Read mode. One Bus Write cycle is required to
issue the Read Memory Array command and return the memory to Read mode. Once the command is issued the memory remains in Read
mode until another command is issued. From
Read mode Bus Read operations will access the
memory array. After power-up or a reset the memory defaults to Read Array mode (Page Read).
While the Program/Erase Controller is executing a
Program, Erase, Block Protect, Blocks Unprotect
or Protection Register Program operation the
memory will not accept the Read Memory Array
command until the operation completes.
Read Electronic Signature Command. The Read
Electronic Signature command is used to read the
Manufacturer Code, the Device Code, the Block
Protection Status and the Protection Register.
One Bus Write cycle is required to issue the Read
Electronic Signature command. Once the command is issued subsequent Bus Read operations
read the Manufacturer Code, the Device Code, the
Block Protection Status or the Protection Register
until another command is issued. Refer to Table
6., Read Electronic Signature, Tables 7 and 8,
Word and Byte-wide Read Protection Register
and Figure 6., Protection Register Memory Map,
for information on the addresses.
Read Query Command. The Read Query Command is used to read data from the Common Flash
Interface (CFI) Memory Area. One Bus Write cycle
is required to issue the Read Query Command.
Once the command is issued subsequent Bus
Read operations read from the Common Flash Interface Memory Area. See APPENDIX B., Tables
24, 25, 26, 27, 28 and 29 for details on the information contained in the Common Flash Interface
(CFI) memory area.
Read Status Register Command. The Read Status Register command is used to read the Status
Register. One Bus Write cycle is required to issue
the Read Status Register command. Once the
command is issued subsequent Bus Read operations read the Status Register until another command is issued.
14/50
The Status Register information is present on the
output data bus (DQ1-DQ7) when the device is enabled and Output Enable is Low, VIL.
See the section on the Status Register and Table
10. for details on the definitions of the Status Register bits
Clear Status Register Command. The Clear Status Register command can be used to reset bits
SR1, SR3, SR4 and SR5 in the Status Register to
‘0’. One Bus Write is required to issue the Clear
Status Register command.
The bits in the Status Register are sticky and do
not automatically return to ‘0’ when a new Write to
Buffer and Program, Erase, Block Protect, Block
Unprotect or Protection Register Program command is issued. If any error occurs then it is essential to clear any error bits in the Status Register by
issuing the Clear Status Register command before
attempting a new Program, Erase or Resume
command.
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. If the block is protected then the
Erase operation will abort, the data in the block will
not be changed and the Status Register will output
the error.
Two Bus Write operations are required to issue the
command; the second Bus Write cycle latches the
block address in the internal state machine and
starts the Program/Erase Controller. Once the
command is issued subsequent Bus Read operations read the Status Register. See the section on
the Status Register for details on the definitions of
the Status Register bits.
During the Erase operation the memory will only
accept the Read Status Register command and
the Program/Erase Suspend command. All other
commands will be ignored. Typical Erase times
are given in Table 9.
See APPENDIX C., Figure 18., Erase Flowchart
and Pseudo Code, for a suggested flowchart on
using the Block Erase command.
Word/Byte Program Command. The
Word/
Byte Program command is used to program a single Word or Byte in the memory array. Two Bus
Write operations are required to issue the command; the first write cycle sets up the Word Program command, the second write cycle latches the
address and data to be programmed in the internal
state machine and starts the Program/Erase Controller.
If the block being programmed is protected an error will be set in the Status Register and the operation will abort without affecting the data in the
M58LW064D
memory array. The block must be unprotected using the Blocks Unprotect command or by using the
Blocks Temporary Unprotect feature of the Reset/
Power-Down pin, RP.
Write to Buffer and Program Command. The
Write to Buffer and Program command is used to
program the memory array.
Up to 16 Words/32 Bytes can be loaded into the
Write Buffer and programmed into the memory.
Each Write Buffer has the same A5-A22 addresses. In Byte-wide mode only A0-A4 may change in
Word-wide mode only A1-A4 may change.
Four successive steps are required to issue the
command.
1. One Bus Write operation is required to set up
the Write to Buffer and Program Command.
Issue the set up command with the selected
memory Block Address where the program
operation should occur (any address in the
block where the values will be programmed
can be used). Any Bus Read operations will
start to output the Status Register after the 1st
cycle.
2. Use one Bus Write operation to write the same
block address along with the value N on the
Data Inputs/Output, where N+1 is the number
of Words/Bytes to be programmed.
3. Use N+1 Bus Write operations to load the
address and data for each Word into the Write
Buffer. See the constraints on the address
combinations listed below. The addresses
must have the same A5-A22.
4. Finally, use one Bus Write operation to issue
the final cycle to confirm the command and
start the Program operation.
Invalid address combinations or failing to follow
the correct sequence of Bus Write cycles will set
an error in the Status Register and abort the operation without affecting the data in the memory array. The Status Register should be cleared before
re-issuing the command.
If the block being programmed is protected an error will be set in the Status Register and the operation will abort without affecting the data in the
memory array. The block must be unprotected using the Blocks Unprotect command.
See APPENDIX C., Figure 16., Write to Buffer and
Program Flowchart and Pseudo Code, for a suggested flowchart on using the Write to Buffer and
Program command.
Program/Erase Suspend Command. The
Program/Erase Suspend command is used to pause a
Word/Byte Program, Write to Buffer and Program
or Erase operation. The command will only be accepted during a Program or an Erase operation. It
can be issued at any time during an Erase opera-
tion but will only be accepted during a Word Program or Write to Buffer and Program command if
the Program/Erase Controller is running.
One Bus Write cycle is required to issue the Program/Erase Suspend command and pause the
Program/Erase Controller. Once the command is
issued it is necessary to poll the Program/Erase
Controller Status bit (SR7) to find out when the
Program/Erase Controller has paused; no other
commands will be accepted until the Program/
Erase Controller has paused. After the Program/
Erase Controller has paused, the memory will continue to output the Status Register until another
command is issued.
During the polling period between issuing the Program/Erase Suspend command and the Program/
Erase Controller pausing it is possible for the operation to complete. Once the Program/Erase
Controller Status bit (SR7) indicates that the Program/Erase Controller is no longer active, the Program Suspend Status bit (SR2) or the Erase
Suspend Status bit (SR6) can be used to determine if the operation has completed or is suspended. For timing on the delay between issuing the
Program/Erase Suspend command and the Program/Erase Controller pausing see Table 9.
During Program/Erase Suspend the Read Memory Array, Read Status Register, Read Electronic
Signature, Read Query and Program/Erase Resume commands will be accepted by the Command Interface. Additionally, if the suspended
operation was Erase then the Write to Buffer and
Program, and the Program Suspend commands
will also be accepted. When a program operation
is completed inside a Block Erase Suspend the
Read Memory Array command must be issued to
reset the device in Read mode, then the Erase Resume command can be issued to complete the
whole sequence. Only the blocks not being erased
may be read or programmed correctly.
See APPENDIX C., Figure 17., Program Suspend
& Resume Flowchart and Pseudo Code, and Figure 19., Erase Suspend & Resume Flowchart and
Pseudo Code, for suggested flowcharts on using
the Program/Erase Suspend command.
Program/Erase Resume Command. The
Program/Erase Resume command can be used to restart the Program/Erase Controller after a
Program/Erase Suspend operation has paused it.
One Bus Write cycle is required to issue the Program/Erase Resume command. Once the command is issued subsequent Bus Read operations
read the Status Register.
Block Protect Command. The Block Protect
command is used to protect a block and prevent
Program or Erase operations from changing the
data in it. Two Bus Write cycles are required to issue the Block Protect command; the second Bus
15/50
M58LW064D
Write cycle latches the block address in the internal state machine and starts the Program/Erase
Controller. Once the command is issued subsequent Bus Read operations read the Status Register. See the section on the Status Register for
details on the definitions of the Status Register
bits.
During the Block Protect operation the memory will
only accept the Read Status Register command.
All other commands will be ignored. Typical Block
Protection times are given in Table 9.
The Block Protection bits are non-volatile, once
set they remain set through reset and powerdown/power-up. They are cleared by a Blocks Unprotect command.
See APPENDIX C., Figure 20., Block Protect
Flowchart and Pseudo Code, for a suggested flowchart on using the Block Protect command.
Blocks Unprotect Command. The Blocks Unprotect command is used to unprotect all of the
blocks. Two Bus Write cycles are required to issue
the Blocks Unprotect command; the second Bus
Write cycle starts the Program/Erase Controller.
Once the command is issued subsequent Bus
Read operations read the Status Register. See the
section on the Status Register for details on the
definitions of the Status Register bits.
During the Block Unprotect operation the memory
will only accept the Read Status Register command. All other commands will be ignored. Typical
Block Protection times are given in Table 9.
See APPENDIX C., Figure 21., Blocks Unprotect
Flowchart and Pseudo Code, for a suggested flowchart on using the Block Unprotect command.
Protection Register Program Command. The
Protection Register Program command is used to
Program the 64 bit user segment of the Protection
Register. Two write cycles are required to issue
the Protection Register Program command.
■
The first bus cycle sets up the Protection
Register Program command.
■
The second latches the Address and the Data
to be written to the Protection Register and
starts the Program/Erase Controller.
Read operations output the Status Register content after the programming has started.
16/50
The user-programmable segment can be locked
by programming bit 1 of the Protection Register
Lock location to ‘0’ (see Table 7. and Table 8. for
Word-wide and Byte-wide protection addressing).
Bit 0 of the Protection Register Lock location locks
the factory programmed segment and is programmed to ‘0’ in the factory. The locking of the
Protection Register is not reversible, once the lock
bits are programmed no further changes can be
made to the values stored in the Protection Register, see Figure 6., Protection Register Memory
Map. Attempting to program a previously protected Protection Register will result in a Status Register error.
The Protection Register Program cannot be suspended. See APPENDIX C., Figure 22., Protection Register Program Flowchart and Pseudo
Code, for the flowchart for using the Protection
Register Program command.
Configure STS Command.
The Configure STS command is used to configure
the Status/(Ready/Busy) pin. After power-up or reset the STS pin is configured in Ready/Busy
mode. The pin can be configured in Status mode
using the Configure STS command (refer to Status/(Ready/Busy) section for more details.
Two write cycles are required to issue the Configure STS command.
■
The first bus cycle sets up the Configure STS
command.
■
The second specifies one of the four possible
configurations (refer to Table 5., Configuration
Codes):
– Ready/Busy mode
– Pulse on Erase complete mode
– Pulse on Program complete mode
– Pulse on Erase or Program complete
mode
The device will not accept the Configure STS command while the Program/Erase controller is busy
or during Program/Erase Suspend. When STS pin
is pulsing it remains Low for a typical time of
250ns. Any invalid Configuration Code will set an
error in the Status Register.

STATUS REGISTER
The Status Register provides information on the
current or previous Program, Erase, Block Protect
or Blocks Unprotect operation. The various bits in
the Status Register convey information and errors
on the operation. They are output on DQ7-DQ0.
To read the Status Register the Read Status Register command can be issued. The Status Register
is automatically read after Program, Erase, Block
Protect, Blocks Unprotect and Program/Erase Resume commands. The Status Register can be
read from any address.
The contents of the Status Register can be updated during an Erase or Program operation by toggling the Output Enable pin or by de-activating and
then reactivating the device (refer to Table 2., Device Enable).
Status Register bits SR5, SR4, SR3 and SR1 are
associated with various error conditions and can
only be reset with the Clear Status Register command. The Status Register bits are summarized in
Table 10., Status Register Bits. Refer to Table 10.
in conjunction with the following text descriptions.
Program/Erase Controller Status Bit (SR7). The
Program/Erase Controller Status bit indicates
whether the Program/Erase Controller is active or
inactive. When the Program/Erase Controller Status bit is Low, VOL, the Program/Erase Controller
is active and all other Status Register bits are High
Impedance; when the bit is High, VOH, the Program/Erase Controller is inactive.
The Program/Erase Controller Status is Low immediately after a Program/Erase Suspend command is issued until the Program/Erase Controller
pauses. After the Program/Erase Controller pauses the bit is High.
During Program, Erase, Block Protect and Blocks
Unprotect operations the Program/Erase Controller Status bit can be polled to find the end of the
operation. The other bits in the Status Register
should not be tested until the Program/Erase Controller completes the operation and the bit is High.
After the Program/Erase Controller completes its
operation the Erase Status, Program Status and
Block Protection Status bits should be tested for
errors.
Erase Suspend Status Bit (SR6). The
Erase
Suspend Status bit indicates that an Erase operation has been suspended and is waiting to be resumed. The Erase Suspend Status should only be
considered valid when the Program/Erase Controller Status bit is High (Program/Erase Controller
inactive); after a Program/Erase Suspend command is issued the memory may still complete the
operation rather than entering the Suspend mode.
20/50
When the Erase Suspend Status bit is Low, VOL,
the Program/Erase Controller is active or has completed its operation; when the bit is High, VOH, a
Program/Erase Suspend command has been issued and the memory is waiting for a Program/
Erase Resume command.
When a Program/Erase Resume command is issued the Erase Suspend Status bit returns Low.
Erase Status Bit (SR5). The Erase Status bit can
be used to identify if the memory has failed to verify that the block has erased correctly or that all
blocks have been unprotected successfully. The
Erase Status bit should be read once the Program/
Erase Controller Status bit is High (Program/Erase
Controller inactive).
When the Erase Status bit is Low, VOL, the memory has successfully verified that the block has
erased correctly or all blocks have been unprotected successfully. When the Erase Status bit is
High, VOH, the erase operation has failed. Depending on the cause of the failure other Status
Register bits may also be set to High, VOH.
■
If only the Erase Status bit (SR5) is set High,
VOH, then the Program/Erase Controller has
applied the maximum number of pulses to the
block and still failed to verify that the block has
erased correctly or that all the blocks have
been unprotected successfully.
■
If the failure is due to an erase or blocks
unprotect with VPEN low, VOL, then VPEN
Status bit (SR3) is also set High, VOH.
■
If the failure is due to an erase on a protected
block then Block Protection Status bit (SR1) is
also set High, VOH.
■
If the failure is due to a program or erase
incorrect command sequence then Program
Status bit (SR4) is also set High, VOH.
Once set High, the Erase Status bit can only be reset Low by a Clear Status Register command or a
hardware reset. If set High it should be reset before a new Program or Erase command is issued,
otherwise the new command will appear to fail.
Program Status Bit (SR4). The Program Status
bit is used to identify a Program or Block Protect
failure. The Program Status bit should be read
once the Program/Erase Controller Status bit is
High (Program/Erase Controller inactive).
When the Program Status bit is Low, VOL, the
memory has successfully verified that the Write
Buffer has programmed correctly or the block is
protected. When the Program Status bit is High,
VOH, the program or block protect operation has
failed. Depending on the cause of the failure other
Status Register bits may also be set to High, VOH.
M58LW064D
If only the Program Status bit (SR4) is set
High, VOH, then the Program/Erase Controller
has applied the maximum number of pulses to
the byte and still failed to verify that the Write
Buffer has programmed correctly or that the
Block is protected.
■
If the failure is due to a program or block
protect with VPEN low, VOL, then VPEN Status
bit (SR3) is also set High, VOH.
■
If the failure is due to a program on a protected
block then Block Protection Status bit (SR1) is
also set High, VOH.
■
If the failure is due to a program or erase
incorrect command sequence then Erase
Status bit (SR5) is also set High, VOH.
Once set High, the Program Status bit can only be
reset Low by a Clear Status Register command or
a hardware reset. If set High it should be reset before a new Program or Erase command is issued,
otherwise the new command will appear to fail.
VPEN Status Bit (SR3). The VPEN Status bit can
be used to identify if a Program, Erase, Block Protection or Block Unprotection operation has been
attempted when VPEN is Low, VIL.
When the VPEN Status bit is Low, VOL, no Program, Erase, Block Protection or Block Unprotection operations have been attempted with VPEN
Low, VIL, since the last Clear Status Register command, or hardware reset. When the VPEN Status
bit is High, VOH, a Program, Erase, Block Protection or Block Unprotection operation has been attempted with VPEN Low, VIL.
Once set High, the VPEN Status bit can only be reset by a Clear Status Register command or a hardware reset. If set High it should be reset before a
new Program, Erase, Block Protection or Block
Unprotection command is issued, otherwise the
new command will appear to fail.
■
Program Suspend Status Bit (SR2). The Program Suspend Status bit indicates that a Program
operation has been suspended and is waiting to
be resumed. The Program Suspend Status should
only be considered valid when the Program/Erase
Controller Status bit is High (Program/Erase Controller inactive); after a Program/Erase Suspend
command is issued the memory may still complete
the operation rather than entering the Suspend
mode.
When the Program Suspend Status bit is Low,
VOL, the Program/Erase Controller is active or has
completed its operation; when the bit is High, VOH,
a Program/Erase Suspend command has been issued and the memory is waiting for a Program/
Erase Resume command.
When a Program/Erase Resume command is issued the Program Suspend Status bit returns Low.
Block Protection Status Bit (SR1). The Block
Protection Status bit can be used to identify if a
Program or Erase operation has tried to modify the
contents of a protected block.
When the Block Protection Status bit is Low, VOL,
no Program or Erase operations have been attempted to protected blocks since the last Clear
Status Register command or hardware reset;
when the Block Protection Status bit is High, VOH,
a Program (Program Status bit SR4 set High) or
Erase (Erase Status bit SR5 set High) operation
has been attempted on a protected block.
Once set High, the Block Protection Status bit can
only be reset Low by a Clear Status Register command or a hardware reset. If set High it should be
reset before a new Program or Erase command is
issued, otherwise the new command will appear to
fail.
Reserved (SR0). Bit SR0 of the Status Register
is reserved. Its value should be masked.

APPENDIX B. COMMON FLASH INTERFACE - CFI
The Common Flash Interface is a JEDEC approved, standardized data structure that can be
read from the Flash memory device. It allows a
system software to query the device to determine
various electrical and timing parameters, density
information and functions supported by the memory. The system can interface easily with the de-
vice, enabling the software to upgrade itself when
necessary.
When the CFI Query Command (RCFI) is issued
the device enters CFI Query mode and the data
structure is read from the memory. Tables 24, 25,
26, 27, 28 and 29 show the addresses used to retrieve the data.
