SUMMARY DESCRIPTION
The M29F010B is a 1 Mbit (128Kb x8) non-volatile memory that can be read, erased and repro­grammed. These operations can be performed us­ing a single 5V suppl y. On power-up t he memory defaults to its Read m ode whe re it can b e read in the same way as a ROM or EPROM.
The memory is divided into blocks that can be erased independentl y s o it is pos si bl e to pres er ve valid data w hile old da ta is erase d. Eac h block c an be protected independ ently to prevent accidental Program or Erase co mmands from modifyin g the memory. Program an d E ras e c om man ds are wri t­ten to the Command I nterface 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.
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 PLCC32, TSOP32 (8 x 20mm) packages and it is supplied with all the bits erased (set to ’1’).
In order to meet environm ental requirement s, ST offers the M29F010B in ECOPACK ECOPACK packages are Lead-free. The category of second Level Interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97.

SIGNAL DESCRIPTIONS
See Figure 1, Lo gic Diagram, an d Table 1, S ignal Names, for a brief overview of the signals connect­ed to this device.
Address Inputs (A0-A16). 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 internal state machine.
Data Inputs/Outputs (DQ0-DQ7). The Data In­puts/Outputs output the data stored at the selected address during a Bus Rea d ope ra tio n. Dur ing B us Write operations they represent the commands sent to the Command Interface of the internal state machine.
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
Output Enable (G
, all other pins are ignored.
IH
). The Output Enable, G, con-
trols the Bus Read operation of the memory.
Write Enable (W
). The Write Enable, W, control s
the Bus Write operation of the memory’s Com­mand Interface.

BUS OPERATIONS
There are five standard bus operations that control the device. These are Bus Read, Bus Writ e, Out­put Disable, Standby and Automatic Standby. See Table 4, Bus Operations, for a summary. Typically glitches of less than 5ns on Chip En able or Write Enable are ignored by the m emo ry 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 s ig nal, V
, to Chip Enable
IL
and Output Enable and keeping Write Enable High, V
. The Data Inputs/Outputs will ou tpu t the
IH
value, see Figure 8, Read Mode AC Waveforms, and Table 11, Read AC Characteristics, for details of when the output becomes valid.
Bus Write. Bus Write operations write to the Command Interface. A v alid Bus Write operati on begins by setting the desired address on the Ad­dress Inputs. The Ad dress Inputs are latched b y the Command Interface on the falling edge of Chip Enable or Write Enable, whichever occurs last. The Data Inputs/Outputs ar e latched by the Com ­mand Interface on the rising ed ge of Chip Enab le or Write Enable, whichever occurs first. Output En­able must remain High, V
, during the whole Bus
IH
Write operation. See Figures 9 and 10, Write AC Waveforms, and Tables 12 and 13, 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, V
IH
, the Data Inputs/Outputs pins are pl aced in the high­impedance state and the Supply Current is re­duced to the Standby level.

The Data Inputs/Outputs will still output data if a Bus Read operation is in progress.
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 us e by progr ammin g equip ­ment and are not usually used in applications. They require V
to be applied to some pins.
ID
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 b e read b y apply ing the sig nals listed in Table 4, Bus Operations.
Block Protection and Blocks Unprotection. Each block can be separately protected against acci­dental Program or Erase. Protected blocks can be unprotected to allow data to be changed. Block Protection and Blocks Unprotection operations must only be performed on programming equip­ment. For further informa tion refer to Application Note AN1122, Applying Protectio n and Unpr otec­tion to M29 Series Flash.

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 operation s will result in the memory return ­ing to Read mode. The long command sequences are imposed to maximize data security.
The commands are summarized in Table 5, Com­mands. Refer to Table 5 in conjunction with the text descriptions below.
Read/Reset Command. The Read/Reset com­mand returns the memory to its Read mode where it behaves lik e a ROM or EPROM. I t also resets the errors in the Status Register. Either one or three Bus Write o perations can be us ed to issue the Read/Reset command.
If the Read/Reset command is issued during a Block Erase operation or following a Programming or Erase error then the memory will take upto 10
µs
to abort. During the abort period no valid data can be read from the memory. Issu ing a Read/Reset command during a Block Erase operation will leave invalid data in the memory.
Auto Select Command. The Auto Select com­mand is used to read t he Manu facturer Code, the Device Code and the Block Protection Status. Three consecutive Bus Write operations are re­quired to issue the Auto Sel ect command. Once the Auto Select comman d is issued the memory remains in Auto Sele ct mode until another com­mand is issued.
From the Auto Select mode the Manufacturer Code can be read using a Bus Read operation with A0 = V may be set to either V
and A1 = VIL. The other address bits
IL
or VIH. The Manufacturer
IL
Code for STMicroelectronics is 20h.
The Device Code ca n be read using a Bu s Read operation with A0 = V address bits may be s et to either V
and A1 = VIL. The other
IH
or VIH. The
IL
Device Code for the M29F010B is 20h. The Block Protectio n Statu s of ea ch block c an be
read using a Bus Read ope ration with A0 = V A1 = V
, and A14-A16 spec ifying the addr ess of
IH
IL
the block. The other address bits may be set to ei­ther V
or VIH. If the addressed block is protected
IL
then 01h is output on the Data Inputs/Outputs, oth­erwise 00h is output.
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 in the internal state machine and starts the Program/Erase Con­troller.
If the address falls in a protect ed block then the Program command is ignored, the data remains unchanged. The Status Register is never read and no error condition is given.
During the program operation th e memory will ig ­nore all commands. It is no t possib le to is sue any command to abort or pause the operation. Typical program times are given in Table 6. Bus Read op­erations during the p rogram 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 Statu s 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 t o ’1’. One of the Erase Com-
,
5/20
M29F010B
mands must be used to set all the bits in a block or in the whole memory from ’0’ to ’1’.
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 Bu s Write operations are r equired to issue the Unlock Bypass command.
Once the Unlock Bypass command has been is­sued the memory will only accept the Unlock By­pass Program com mand and the Unlock B ypass Reset command. The memory can be read as if in Read mode.
Unlock Bypass Program Command. The Un­lock Bypass Program command can be used to program one address in memory at a time. The command requires t wo Bus Write oper ations, the final write operati on lat ches the ad dress and d ata in the internal state machine and starts the Pro­gram/Erase Controller.
The Program operation us ing the Unlock Bypass Program command behaves identically to the Pro­gram operation using the Program command. A protected block cannot be progra mme d; the op er­ation cannot be aborted and the Status Register is read. Errors must be reset using the Read/Reset command, which leav es the device in Unlock By­pass Mode. See the Program command for details on the behavior.
Unlock Bypass Reset Command. The Unlock Bypass Reset comm and can b e used to return to Read/Reset mode from Unlock Bypass Mode. Two Bus Write operations are required to issue the Unlock Bypass Reset command.
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 within about 100µs, leaving the data unc hanged . No er ror con dition 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. 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 o per at ion has c om ple ted the memory will return to the Read Mode, unless an error has occurred. When an error occurs the memory will continue to output the Statu s 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.
Block Erase Command. The Block Erase com­mand can be used to erase a l ist of one or more blocks. Six Bus W rite operations are required to select the first block in the list. Each additional block in the lis t can be selec ted by repeating the sixth Bus Write operation using the address of the additional block. The Bloc k Er as e op erati on st ar ts 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 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 sel ected blocks are pr otected 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 Eras e o perat ion the memory will ignore all comman ds except the Erase Suspend and Read/Reset commands . Typical block erase times are given in Table 6. All Bus Read opera­tions during the B lock Erase op eration wil l 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 Statu s Regis­ter. A Read/Reset command must be issued to re­set the error condition and return to Read mode.
The Block Erase Comma nd sets all of the bits in the unprotected selected blocks to ’1’. All previous data in the selected blocks is lost.
Erase Suspend Command. The Erase S u sp en d Command may be used to tempor arily suspend a
6/20
M29F010B
Block Erase operation a nd return the memory to Read mode. The command requires one Bus Write operation.
The Program/Erase Control ler will sus pend with in 15µs 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 additiona l block (before the Program/Erase Controller starts) then the
both Read and Program operations behave as normal on these bloc ks. Re adi ng fro m b lock s t hat are being erased will output the Status Register. It is also possible to enter the Auto Select mode: the memory wil l behav e as in t he Auto Select mo de on all blocks until a Read/Reset command returns the memory to Erase Suspend mode.
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.
Erase is suspende d i mme di atel y and wil l sta rt im ­mediately when the Eras e Resume Command is issued. It will not be possib le to select an y further blocks for erasure after the Erase Resume.
During Erase Suspend i t is possible to Read and Program cells in blocks that are not being erased;

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 Reg ist er ar e sum ma rize d i n Table 7, 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 or if it has res ponded 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 outp ut DQ7, not its com­plement.
During Erase operations the Data Pollin g 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 Suspen d mode the Data Polling Bit will output a ’1’ during a Bus Read oper ation 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 4, Data Polling Flowchart, gives an exam­ple of how to use the Data Polling Bi t. 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 or if it has re­sponded to an Erase S uspend. The Togg le Bit is output on DQ6 when the Status Register is read.
During Program and Er ase oper ation s the Tog gle Bit changes from ’0’ to ’1’ to ’0’ , etc., with s ucces­sive 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.
Figure 5, Data Toggle Flowch art, 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 Pr o­gram, Block Erase or Chip Erase operation fails to write the correct data to the memor y. If the Error Bit is set a Read/Reset comma nd mu st be issue d before other comman ds 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 at ’0’ back to ’1’ and attempting to do so may or may not set D Q5 at ‘ 1’. In bo th cases, a succes ­sive Bus Read operation will show the bit is still ’0’. One of the Erase commands mu st be used to set all the bits in a block or in the whole memory from ’0’ to ’1’.
Erase Timer Bit (DQ3). T he Er ase Tim er Bi t 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 Contr oller starts the Erase Timer Bit is set to ’0’ an d addition al blocks to be erase d may be written to the Command Interface. 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/
8/20
M29F010B
Erase controller d uring 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., wi th successive Bus Rea d operations from ad dresses within the blocks 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 b ei ng e rase d wi ll output the memory cell data as if in Read mode.
After an Erase o per at ion th at ca us es th e Er ror B it 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 with in blocks that have not erased correctly. Th e Alternative Toggle B it does not change if the addressed block has erased cor­rectly.
