Description
The following overview of the Numonyx® Axcell™ M29F 5 V Flash Memory device
(M29W160F) refers to the 16-Mbit device. However, the information can also apply to lower
densities of the M29F device.
The M29F160F is a 16 Mbit (2 Mbit x8 or 1 Mbit x16) non-volatile memory that can be read,
erased and reprogrammed. These operations can be performed using a single low voltage
(4.5 to 5.5 V) 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 blocks that can be erased independently so it is possible to
preserve valid data while old data is erased. Each block can be protected independently to
prevent accidental Program or Erase commands from modifying the memory. 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. The command set required to control the memory is consistent with JEDEC
standards.
The blocks in the memory are asymmetrically arranged, as shown in Figure 10.: Block
Addresses, M29F160 (x8) and Figure 11.: Block Addresses, M29F160 (x16). The first or last
64 KBytes have been divided into four additional blocks. The 16 KByte Boot Block can be
used for small initialization code to start the microprocessor, the two 8 KByte Parameter
Blocks can be used for parameter storage and the remaining 32K is a small Main Block
where the application may be stored.
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), SO44 , and TFBGA48 (0.8 mm pitch)
packages. The memory is supplied with all the bits erased (set to ’1’).

Signal Descriptions
2
M29FxxxFT, M29FxxxFB
Signal Descriptions
See Figure 1.: Logic Diagram and Table 1.: Signal Names, for a brief overview of the signals
connected to this device.
2.1
Address Inputs (A0-A19)
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.
2.2
Data Inputs/Outputs (DQ0-DQ7)
The Data Inputs/Outputs output 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.
2.3
Data Inputs/Outputs (DQ8-DQ14)
The Data Inputs/Outputs output the data stored at the selected address during a Bus Read
operation when BYTE is High, VIH. When BYTE is Low, VIL, these pins are not used and are
high impedance. During Bus Write operations the Command Register does not use these
bits. When reading the Status Register these bits should be ignored.
2.4
Data Input/Output or Address Input (DQ15A-1)
When BYTE is High, VIH, this pin behaves as a Data Input/Output pin (as DQ8-DQ14).
When BYTE is Low, VIL, this pin behaves as an address pin; DQ15A–1 Low will select the
LSB of the Word on the other addresses, DQ15A–1 High will select the MSB. Throughout
the text consider references to the Data Input/Output to include this pin when BYTE is High
and references to the Address Inputs to include this pin when BYTE is Low except when
stated explicitly otherwise.
2.5
Chip Enable
The Chip Enable, E, activates the memory, allowing Bus Read and Bus Write operations to
be performed. When Chip Enable is High, VIH, all other pins are ignored.
2.6
Output Enable
The Output Enable, G, controls the Bus Read operation of the memory.
20/67
M29FxxxFT, M29FxxxFB
2.7
Signal Descriptions
Write Enable
The Write Enable, W, controls the Bus Write operation of the memory’s Command Interface.
2.8
Reset/Block Temporary Unprotect
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 Output section, Table 18.: Reset/Block Temporary Unprotect AC
Characteristics and Figure 23.: Reset/Block Temporary Unprotect AC Waveforms.
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.
2.9
Ready/Busy Output
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-impedance 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
becomes high-impedance. See Table 18.: Reset/Block Temporary Unprotect AC
Characteristics and Figure 23.: Reset/Block Temporary Unprotect AC Waveforms.
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.
2.10
Byte/Word Organization Select
The Byte/Word Organization Select pin is used to switch between the 8-bit and 16-bit Bus
modes of the memory. When Byte/Word Organization Select is Low, VIL, the memory is in 8bit mode, when it is High, VIH, the memory is in 16-bit mode.
2.11
VCC Supply Voltage
The VCC Supply Voltage supplies the power for all operations (Read, Program, Erase etc.).
The Command Interface is disabled when the VCC 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.
21/67
Signal Descriptions
M29FxxxFT, M29FxxxFB
A 0.1µF capacitor should be connected between the VCC 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.
2.12
VSS Ground
The VSS Ground is the reference for all voltage measurements. The two VSS pins of the
device must be connected to the system ground.
22/67
M29FxxxFT, M29FxxxFB

Bus Operations
Bus Operations
There are five standard bus operations that control the device. These are Bus Read, Bus
Write, Output Disable, Standby and Automatic Standby. See Table 2.: Bus Operations,
BYTE = VIL and Table 3.: Bus Operations, BYTE = VIH 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.
3.1
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, VIL, to Chip Enable and Output Enable and keeping Write
Enable High, VIH. The Data Inputs/Outputs will output the value, see Figure 20.: Read Mode
AC Waveforms and Table 15.: Read AC Characteristics, for details of when the output
becomes valid.
3.2
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 the following figures and tables:
3.3
„
Figure 21.: Write AC Waveforms, Write Enable Controlled
„
Figure 22.: Write AC Waveforms, Chip Enable Controlled,
„
Table 16.: Write AC Characteristics, Write Enable Controlled
„
Table 17.: Write AC Characteristics, Chip Enable Controlled.
Output Disable
The Data Inputs/Outputs are in the high impedance state when Output Enable is High, VIH.
3.4
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 14.: 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.
23/67
Bus Operations
3.5
M29FxxxFT, M29FxxxFB
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.
3.6
Special Bus Operations
Additional bus operations can be performed to read the Electronic Signature and also to
apply and remove Block Protection. These bus operations are intended for use by
programming equipment and are not usually used in applications. They require VID to be
applied to some pins.
3.7
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 Table 2.:
Bus Operations, BYTE = VIL and Table 3.: Bus Operations, BYTE = VIH.
3.8
Block Protection and Block Unprotection
Each block can be separately protected against accidental Program or Erase. Protected
blocks can be unprotected to allow data to be changed.
There are two methods available for protecting and unprotecting the blocks, one for use on
programming equipment and the other for in-system use. Block Protect and Blocks
Unprotect operations are described in Appendix C: Block protection.

Command Interface

M29FxxxFT, M29FxxxFB
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.
The address used for the commands changes depending on whether the memory is in 16bit or 8-bit mode. See either Table 4.: Commands, 16-bit mode, BYTE = VIH, or Table 5.:
Commands, 8-bit mode, BYTE = VIL, depending on the configuration that is being used, for
a summary of the commands.
4.1
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 will not abort an Erase operation when issued while in Erase Suspend.
4.2
Auto Select Command
The Auto Select command is used to read the Manufacturer Code, the Device Code and the
Block Protection Status. 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. Read CFI Query and Read/Reset
commands are accepted in Auto Select mode, all other commands are ignored.
From the Auto Select mode the Manufacturer Code can be read using a Bus Read
operation with A0 = VIL and A1 = VIL. The other address bits may be set to either VIL or VIH.
The Manufacturer Code for Numonyx is 0001h.
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.
The Block Protection Status of each block can be read using a Bus Read operation with A0
= VIL, A1 = VIH, and A12-A19 specifying the address of the block. The other address bits
may be set to either VIL or VIH. If the addressed block is protected then 01h is output on
Data Inputs/Outputs DQ0-DQ7, otherwise 00h is output.
4.3
Program Command
The Program command can be used to program a value to one address in the memory
array at a time. The command requires four Bus Write operations, the final write operation
latches the address and data, and starts the Program/Erase Controller.
If the address falls in a protected block then the Program command is ignored, the data
remains unchanged. The Status Register is never read and no error condition is given.
26/67
M29FxxxFT, M29FxxxFB
Command Interface
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.: Program/Erase Times and Program/Erase Endurance Cycles, M29F160F. 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 returns to the Read mode, unless
an error has occurred. When an error occurs the memory continues 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’.
4.4
Unlock Bypass Command
The Unlock Bypass command is used in conjunction with the Unlock Bypass Program
command to program the memory. When the access time to the device is long (as with
some EPROM programmers) considerable time saving can be made by using these
commands. Three Bus Write operations are required to issue the Unlock Bypass command.
Once the Unlock Bypass command has been issued the memory will only accept the Unlock
Bypass Program command and the Unlock Bypass Reset command. The memory can be
read as if in Read mode.
4.5
Unlock Bypass Program Command
The Unlock Bypass Program command can be used to program one address in memory at
a time. The command requires two Bus Write operations, the final write operation latches
the address and data, and starts the Program/Erase Controller.
The Program operation using the Unlock Bypass Program command behaves identically to
the Program operation using the Program command. A protected block cannot be
programmed; the operation cannot be aborted and the Status Register is read. Errors must
be reset using the Read/Reset command, which leaves the device in Unlock Bypass Mode.
See the Program command for details on the behavior.
4.6
Unlock Bypass Reset Command
The Unlock Bypass Reset command can be used to return to Read/Reset mode from
Unlock Bypass Mode. Two Bus Write operations are required to issue the Unlock Bypass
Reset command. Read/Reset command does not exit from Unlock Bypass Mode.
4.7
Chip Erase Command
The Chip Erase command can be used to erase the entire chip. Six Bus Write operations
are required to issue the Chip Erase Command and start the Program/Erase Controller.
If any blocks are protected then these are ignored and all the other blocks are erased. If all
of the blocks are protected the Chip Erase operation appears to start but will terminate
27/67
Command Interface
M29FxxxFT, M29FxxxFB
within about 100µs, leaving the data unchanged. No error condition is given when protected
blocks are ignored.
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.:
Program/Erase Times and Program/Erase Endurance Cycles, M29F160F. 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.
The Chip Erase Command sets all of the bits in unprotected blocks of the memory to ’1’. All
previous data is lost.
4.8
Block Erase Command
The Block Erase command can be used to erase a list of one or more blocks. Six Bus Write
operations are required to select the first block in the list. Each additional block in the list can
be selected by repeating the sixth Bus Write operation using the address of the additional
block. The Block Erase operation starts the Program/Erase Controller about 50µs after the
last Bus Write operation. Once the Program/Erase Controller starts it is not possible to
select any more blocks. Each additional block must therefore be selected within 50µs of the
last block. The 50µs timer restarts when an additional block is selected. The Status Register
can be read after the sixth Bus Write operation. See the Status Register section for details
on how to identify if the Program/Erase Controller has started the Block Erase operation.
If any selected blocks are protected then these are ignored and all the other selected blocks
are erased. If all of the selected blocks are protected the Block Erase operation appears to
start but will terminate within about 100µs, leaving the data unchanged. No error condition is
given when protected blocks are ignored.
During the Block Erase operation the memory will ignore all commands except the Erase
Suspend command. Typical block erase times are given in Table 6.: Program/Erase Times
and Program/Erase Endurance Cycles, M29F160F. 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.
The Block Erase Command sets all of the bits in the unprotected selected blocks to ’1’. All
previous data in the selected blocks is lost.
4.9
Erase Suspend Command
The Erase Suspend Command may be used to temporarily suspend a Block Erase
operation and return the memory to Read mode. The command requires one Bus Write
operation.
28/67
M29FxxxFT, M29FxxxFB
Command Interface
The Program/Erase Controller will suspend within the Erase Suspend Latency Time (refer to
Table 6.: Program/Erase Times and Program/Erase Endurance Cycles, M29F160F for
value) of the Erase Suspend Command being issued. Once the Program/Erase Controller
has stopped the memory will be set to Read mode and the Erase will be suspended. If the
Erase Suspend command is issued during the period when the memory is waiting for an
additional block (before the Program/Erase Controller starts) then the Erase is suspended
immediately and will start immediately when the Erase Resume Command is issued. It is
not possible to select any further blocks to erase after the Erase Resume.
During Erase Suspend it is possible to Read and Program cells in blocks that are not being
erased; both Read and Program operations behave as normal on these blocks. If any
attempt is made to program in a protected block or in the suspended block then the Program
command is ignored and the data remains unchanged. The Status Register is not read and
no error condition is given. Reading from blocks that are being erased will output the Status
Register.
It is also possible to issue the Auto Select, Read CFI Query and Unlock Bypass commands
during an Erase Suspend. The Read/Reset command must be issued to return the device to
Read Array mode before the Resume command will be accepted.
4.10
Erase Resume Command
The Erase Resume command must be used to restart the Program/Erase Controller from
Erase Suspend. An erase can be suspended and resumed more than once.
4.11
Read CFI Query Command
The Read CFI Query Command is used to read data from the Common Flash Interface
(CFI) Memory Area. This command is valid when the device is in the Read Array mode, or
when the device is in Auto Select mode.
One Bus Write cycle is required to issue the Read CFI Query Command. Once the
command is issued subsequent Bus Read operations read from the Common Flash
Interface Memory Area.
The Read/Reset command must be issued to return the device to the previous mode (the
Read Array mode or Auto Select mode). A second Read/Reset command would be needed
if the device is to be put in the Read Array mode from Auto Select mode.
See Appendix B: Common Flash Interface (CFI) and the following tables for details on the
information contained in the Common Flash Interface (CFI) memory area.

Status Register
5
M29FxxxFT, M29FxxxFB
Status Register
Bus Read operations from any address always read the Status Register during Program
and Erase operations. It is also read during Erase Suspend when an address within a block
being erased is accessed.
The bits in the Status Register are summarized in Table 10.: Status Register Bits.
5.1
Data Polling Bit
The Data Polling Bit (DQ7) can be used to identify whether the Program/Erase Controller
has successfully completed its operation or if it has responded to an Erase Suspend. The
Data Polling Bit is output on DQ7 when the Status Register is read.
During Program operations the Data Polling Bit outputs the complement of the bit being
programmed to DQ7. After successful completion of the Program operation the memory
returns to Read mode and Bus Read operations from the address just programmed output
DQ7, not its complement.
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.
In Erase Suspend mode the Data Polling Bit will output a ’1’ during a Bus Read operation
within a block being erased. The Data Polling Bit will change from a ’0’ to a ’1’ when the
Program/Erase Controller has suspended the Erase operation.
Figure 1. 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.
5.2
Toggle Bit
The Toggle Bit (DQ6) can be used to identify whether the Program/Erase Controller has
successfully completed its operation or if it has responded to an Erase Suspend. 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.
During Erase Suspend mode the Toggle Bit will output when addressing a cell within a block
being erased. The Toggle Bit will stop toggling when the Program/Erase Controller has
suspended the Erase operation.
If any attempt is made to erase a protected block, the operation is aborted, no error is
signalled and DQ6 toggles for approximately 100µs. If any attempt is made to program a
protected block or a suspended block, the operation is aborted, no error is signalled and
DQ6 toggles for approximately 1µs.
Figure 2. Data Toggle Flowchart, gives an example of how to use the Data Toggle Bit.
34/67
M29FxxxFT, M29FxxxFB
5.3
Status Register
Error Bit
The Error Bit (DQ5) 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’
5.4
Erase Timer Bit
The Erase Timer Bit (DQ3) 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’. Before the Program/Erase Controller starts the
Erase Timer Bit is set to ’0’ and additional blocks to be erased may be written to the
Command Interface. The Erase Timer Bit is output on DQ3 when the Status Register is
read.
5.5
Alternative Toggle Bit
The Alternative Toggle Bit (DQ2) can be used to monitor the Program/Erase controller
during Erase operations. The Alternative Toggle Bit is output on DQ2 when the Status
Register is read.
During Chip Erase and Block Erase operations the Toggle Bit changes from ’0’ to ’1’ to ’0’,
etc., with successive Bus Read operations from addresses within the blocks being erased.
A protected block is treated the same as a block not being erased. Once the operation
completes the memory returns to Read mode.
During Erase Suspend the Alternative Toggle Bit changes from ’0’ to ’1’ to ’0’, etc. with
successive Bus Read operations from addresses within the blocks being erased. Bus Read
operations to addresses within blocks not being erased will output the memory cell data as if
in Read mode.
After an Erase operation that causes the Error Bit to be set the Alternative Toggle Bit can be
used to identify which block or blocks have caused the error. The Alternative Toggle Bit
changes from ’0’ to ’1’ to ’0’, etc. with successive Bus Read Operations from addresses
within blocks that have not erased correctly. The Alternative Toggle Bit does not change if
the addressed block has erased correctly.

Common Flash Interface (CFI)
Appendix B
M29FxxxFT, M29FxxxFB
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 device, enabling the
software to upgrade itself when necessary.
When the CFI Query Command is issued the device enters CFI Query mode and the data
structure is read from the memory. Addresses used to retrieve the data are shown in the
following tables:
„
Table 31.: Query Structure Overview,
„
Table 32.: CFI Query Identification String,
„
Table 33.: CFI Query System Interface Information,
„
Table 34.: Device Geometry Definition,
„
Table 35.: Primary Algorithm-Specific Extended Query Table
„
Table 36.: Security Code Area
The CFI data structure also contains a security area where a 64-bit unique security number
is written (see Table 36.: Security Code Area). This area can be accessed only in Read
mode by the final user. It is impossible to change the security number after it has been
written by Numonyx. Issue a Read command to return to Read mode.

Block protection
Appendix C
M29FxxxFT, M29FxxxFB
Block protection
Block protection can be used to prevent any operation from modifying the data stored in the
Flash memory. Each Block can be protected individually. Once protected, Program and
Erase operations on the block fail to change the data.
There are three techniques that can be used to control Block Protection, these are the
Programmer technique, the In-System technique and Temporary Unprotection. Temporary
Unprotection is controlled by the Reset/Block Temporary Unprotection pin, RP; this is
described in the Signal Descriptions section.
Unlike the Command Interface of the Program/Erase Controller, the techniques for
protecting and unprotecting blocks could change between different Flash memory suppliers.
C.1
Programmer Technique
The Programmer technique uses high (VID) voltage levels on some of the bus pins. These
cannot be achieved using a standard microprocessor bus, therefore the technique is
recommended only for use in Programming Equipment.
To protect a block follow the flowchart in Figure 27.: Programmer Equipment Block Protect
Flowchart. During the Block Protect algorithm, the A19-A12 Address Inputs indicate the
address of the block to be protected. The block will be correctly protected only if A19-A12
remain valid and stable, and if Chip Enable is kept Low, VIL, all along the Protect and Verify
phases.
The Chip Unprotect algorithm is used to unprotect all the memory blocks at the same time.
This algorithm can only be used if all of the blocks are protected first. To unprotect the chip
follow Figure 28.: Programmer Equipment Chip Unprotect Flowchart and Table 37.:
Programmer Technique Bus Operations, BYTE = VIH or VIL, which give a summary of each
operation.
The timing on these flowcharts is critical. Care should be taken to ensure that, where a
pause is specified, it is followed as closely as possible. Do not abort the procedure before
reaching the end. Chip Unprotect can take several seconds and a user message should be
provided to show that the operation is progressing.
C.2
In-System Technique
The In-System technique requires a high voltage level on the Reset/Blocks Temporary
Unprotect pin, RP. This can be achieved without violating the maximum ratings of the
components on the microprocessor bus, therefore this technique is suitable for use after the
Flash memory has been fitted to the system.
To protect a block follow the flowchart in Figure 29.: In-System Equipment Block Protect
Flowchart. To unprotect the whole chip it is necessary to protect all of the blocks first, then
all the blocks can be unprotected at the same time. To unprotect the chip follow Figure 30.:
In-System Equipment Chip Unprotect Flowchart.
The timing on these flowcharts is critical. Care should be taken to ensure that, where a
pause is specified, it is followed as closely as possible. Do not allow the microprocessor to
service interrupts that will upset the timing and do not abort the procedure before reaching
60/67
M29FxxxFT, M29FxxxFB

the end. Chip Unprotect can take several seconds and a user message should be provided
to show that the operation is progressing.
