GENERAL DESCRIPTION MX29LV320E T/B is a 32Mbit flash memory that can be organized as 4Mbytes of 8 bits each or 2Mbytes of 16 bits each. These devices operate over a voltage range of 2.7V to 3.6V typically using a 3V power supply input. The memory array is divided into 64 equal 64 Kilo byte blocks. However, depending on the device being used as a Top-Boot or Bottom-Boot device, the top or the bottom first block is further subdivided into 8 equal 8Kbyte blocks. The outermost two sectors at the top or at the bottom can be protected at the boot blocks for this device. This flash memory also provides an additional factory lockable or customer lockable 256byte sector to provide security feature. The MX29LV320E T/B is offered in a 44-pin SOP, a 48-pin TSOP and a 48-ball BGA(TFBGA/LFBGA) JEDEC standard package. These packages are offered in leaded, as well as lead-free versions that are compliant to the RoHS specifications. The software algorithm used for this device also adheres to the JEDEC standard for single power supply devices. These flash parts can be programmed in system or on commercially available EPROM/ Flash programmers. Separate OE# and CE# (Output Enable and Chip Enable) signals are provided to simplify system design. When used with high speed processors, the 70ns read access time of this flash memory permits operation with minimal time lost due to system timing delays. The automatic erase algorithm provided on Macronix flash memories perform an automatic program prior to program. The user only needs to provide a write command to the command register. The on-chip state machine automatically controls the program and erase functions including all necessary internal timings. Since erase operations take much longer time than read operations, erase can be interrupted to perform read operations in other sectors of the device. For this, Erase Suspend operation along with erase resume operation are provided. Data# polling or toggle bits are used to indicate the end of the erase/program operation. These devices are manufactured at the Macronix fabrication facility using the time tested and proven Macronix's advanced technology. This proprietary non-epi process provides a very high degree of latch-up protection for stresses up to 100 milliamperes on address and data pins from -1V to 1.5xVCC. With low power consumption and enhanced hardware and software features, this flash memory retains data reliably for at least twenty years. Erase and programming functions have been tested to meet a typical specification of 100,000 cycles of operation.

Each block in the block diagram represents one or more circuit modules in the real chip used to access, erase, program, and read the memory array.. The "CONTROL INPUT LOGIC" block receives input pins CE#, OE#, WE#, RESET#, BYTE#, and WP#/ACC. It creates internal timing control signals according to the input pins and outputs to the "ADDRESS LATCH AND BUFFER" to latch the external address pins A0-AM(A20). The internal addresses are output from this block to the main array and decoders composed of "X-DECODER", "Y-DECODER", "Y-PASS GATE", and "FLASH ARRAY". The X-DECODER decodes the word-lines of the flash array, while the Y-DECODER decodes the bit-lines of the flash array. The bit lines are electrically connected to the "SENSE AMPLIFIER" and "PGM DATA HV" selectively through the y-pass gates. Sense amplifiers are used to read out the contents of the flash memory, while the "PGM DATA HV" block is used to selectively deliver high power to bit-lines during programming. The "I/O BUFFER" controls the input and output on the Q0-Q15/A-1 pads. During read operation, the I/O buffer receives data from sense amplifiers and drives the output pads accordingly. In the last cycle of program command, the I/O buffer transmits the data on Q0-Q15/A-1 to "PROGRAM DATA LATCH", which controls the high power drivers in "PGM DATA HV" to selectively program the bits in a word or byte according to the user input pattern. The "PROGRAM/ERASE HIGH VOLTAGE" block comprises the circuits to generate and deliver the necessary high voltage to the X-DECODER, FLASH ARRAY, and "PGM DATA HV" block. The logic control module comprises of the "WRITE STATE MACHINE (WSM)", "STATE REGISTER", "COMMAND DATA DECODER", and "COMMAND DATA LATCH". When the user issues a command by toggling WE#, the command on Q0-Q15/A-1 is latched in the command data latch and is decoded by the command data decoder. The state register receives the command and records the current state of the device. The WSM implements the internal algorithms for program or erase according to the current command state by controlling each block in the block diagram. P/N:PM1575 REV. 1.3, DEC. 19, 2013 10 MX29LV320E T/B BLOCK STRUCTURE The main flash memory array can be organized as 4M Bytes x 8 or as 2M Words x 16.

P/N:PM1575 REV. 1.3, DEC. 19, 2013 16 MX29LV320E T/B FUNCTIONAL OPERATION DESCRIPTION READ OPERATION To perform a read operation, the system addresses the desired memory array or status register location by providing its address on the address pins and simultaneously enabling the chip by driving CE# & OE# LOW, and WE# HIGH. After the Tce and Toa timing requirements have been met, the system can read the contents of the addressed location by reading the Data (I/O) pins. If either the CE# or OE# is held HIGH, the outputs will remain tri-stated and no data will appear on the output pins. WRITE OPERATION To perform a write operation, the system provides the desired address on the address pins, enables the chip by asserting CE# LOW, and disables the Data (I/O) pins by holding OE# HIGH. The system then places data to be written on the Data (I/O) pins and pulses WE# LOW. The device captures the address information on the falling edge of WE# and the data on the rising edge of WE#. To see an example, please refer to the timing diagram in Figure 1. The system is not allowed to write invalid commands (commands not defined in this datasheet) to the device. Writing an invalid command may put the device in an undefined state. DEVICE RESET Driving the RESET# pin LOW for a period of Trp or more will return the device to Read mode. If the device is in the middle of a program or erase operation, the reset operation will take at most a period of Tready1 before the device returns to Read mode. Until the device does returns to Read mode, the RY/BY# pin will remain Low (Busy Status). When the RESET# pin is held at GND±0.3V, the device only consumes standby (Isbr) current. However, the device draws larger current if the RESET# pin is held at a voltage greater than GND+0.3V and less than or equal to Vil. It is recommended to tie the system reset signal to the RESET# pin of the flash memory. This allows the device to be reset with the system and puts it in a state where the system can immediately begin reading boot code from it. STANDBY MODE The device enters Standby mode whenever the RESET# and CE# pins are both held High. While in this mode, WE# and OE# will be ignored, all Data Output pins will be in a high impedance state, and the device will draw minimal (Isb) current. OUTPUT DISABLE While in active mode (RESET# HIGH and CE# LOW), the OE# pin controls the state of the output pins. If OE# is held HIGH, all Data (I/O) pins will remain tri-stated. If held LOW, the Byte or Word Data (I/O) pins will drive data. P/N:PM1575 REV. 1.3, DEC. 19, 2013 17 MX29LV320E T/B FUNCTIONAL OPERATION DESCRIPTION (cont'd) BYTE/WORD SELECTION The BYTE# input pin is used to select the organization of the array data and how the data is input/output on the Data (I/O) pins. If the BYTE# pin is held HIGH, Word mode will be selected and all 16 data lines (Q15 to Q0) will be active. If BYTE# is forced LOW, Byte mode will be active and only data lines Q7 to Q0 will be active. Data lines Q8 to Q14 will remain in a high impedance state and Q15 becomes the A-1 address input pin. HARDWARE WRITE PROTECT By driving the WP#/ACC pin LOW, the outermost two boot sectors are protected from all erase/program operations. If WP#/ACC is held HIGH (Vih to VCC), these two outermost sectors revert to their previously protected/ unprotected status. ACCELERATED PROGRAMMING OPERATION By applying high voltage (Vhv) to the WP#/ACC pin, the device will enter the Accelerated Programming mode. This mode permits the system to skip the normal command unlock sequences and program byte/word locations directly. During accelerated programming, the current drawn from the WP#/ACC pin is no more than Icp1. TEMPORARY SECTOR GROUP UNPROTECT OPERATION The system can apply Vhv to the RESET# pin to place the device in Temporary Unprotect mode. In this mode, previously protected sectors can be programmed/erased just as though they were unprotected. The device returns to normal operation once Vhv is removed from the RESET# pin and previously protected sectors will once again be protected. SECTOR GROUP PROTECT OPERATION The MX29LV320E T/B provides user programmable protection against program/erase operations for selected sectors. Most sectors cannot protected individually. Instead, they are bound in groups of four or less called Sector-Groups. Protection is available for individual Sector-Groups, which includes all member sectors. Boot sectors are the exception to this rule as they are assigned unique Sector-Group addresses and can be protected individually without protecting any adjacent sectors or Sector-Groups. The three sectors adjacent to the boot sectors form a non-standard Sector-Group. Please refer to Table 1a and Table 1b which show all Sector-Group assignments. During the protection operation, the sector address of any sector within a Sector-Group may be used to specify the Sector-Group being protected. There are two methods available to protect Sector-Groups. The first and preferred method is activated by applying Vhv on the RESET# pin and following the timing in Figure 13 and the algorithm shown in Figure 14. This is a command operation that can be performed either on an external programmer or in-circuit by the system controller. The second method is strictly a bus operation and is entered by asserting Vhv on A9 and OE# pins, with A6 and CE# at Vil. The protection operation begins at the falling edge of WE# and terminates at the rising edge. Contact Macronix for more details on this method. P/N:PM1575 REV. 1.3, DEC. 19, 2013 18 MX29LV320E T/B FUNCTIONAL OPERATION DESCRIPTION (cont'd) CHIP UNPROTECT OPERATION The Chip Unprotect operation unprotects all sectors within the device. It is standard procedure and highly recommended to protect all Sector-Groups prior using the Chip Unprotect operation. This will prevent possible damage to the Sector-Group protection logic. All Sector Groups are unprotected when shipped from the factory, so this operation is only necessary if the user has previously protected any Sector-Groups and wishes to unprotect them now. MX29LV320E T/B provides two methods for unprotecting the entire chip. The first and preferred method is entered by applying Vhv on RESET# pin and following the timing diagram in Figure 13 and using the algorithm shown in Figure 15. The second method is entered by asserting Vhv on A9 and OE# pins, with A6 at Vih and CE# at Vil. The protection operation begins at the falling edge of WE# and terminates at the rising edge. Contact Macronix for more details on this method. AUTOMATIC SELECT BUS OPERATIONS The following five bus operations require A9 to be raised to Vhv. Please see AUTOMATIC SELECT COMMAND SEQUENCE in the COMMAND OPERATIONS section for details of equivalent command operations that do not require the use of Vhv. SECTOR LOCK STATUS VERIFICATION To determine the protected state of any sector using bus operations, the system performs a READ OPERATION with A9 raised to Vhv, the sector address applied to address pins A20 to A12, address pins A6 & A0 held LOW, and address pin A1 held HIGH. If data bit Q0 is LOW, the sector is not protected, and if Q0 is HIGH, the sector is protected. READ SILICON ID MANUFACTURER CODE To determine the Silicon ID Manufacturer Code, the system performs a READ OPERATION with A9 raised to Vhv and address pins A6, A1, & A0 held LOW. The Macronix ID code of C2h should be present on data bits Q7 to Q0. READ SILICON ID MX29LV320ET CODE To verify the Silicon ID MX29LV320ET Code, the system performs a READ OPERATION with A9 raised to Vhv, address pins A6 & A1 held LOW, and address pin A0 held HIGH. The MX29LV320ET code of A7h should be present on data bits Q7 to Q0. Q15 to Q8 will be tri-stated unless Word mode is selected. In this case, Q15 to Q8 will output the value 22h. READ SILICON ID MX29LV320EB CODE To verify the Silicon ID MX29LV320EB Code, the system performs a READ OPERATION with A9 raised to Vhv, address pins A6 & A1 held LOW, and address pin A0 held HIGH. The MX29LV320ET code of A8h should be present on data bits Q7 to Q0. Q15 to Q8 will be tri-stated unless Word mode is selected. In this case, Q15 to Q8 will output the code 22h. P/N:PM1575 REV. 1.3, DEC. 19, 2013 19 MX29LV320E T/B FUNCTIONAL OPERATION DESCRIPTION (cont'd) READ INDICATOR BIT (Q7) FOR SECURITY SECTOR To determine if the Security Sector has been locked at the factory, the system performs a READ OPERATION with A9 raised to Vhv, address pin A6 held LOW, and address pins A1 & A0 held HIGH. If the Security Sector has been locked at the factory, the code 99h will be present on data bits Q7 to Q0. Otherwise, the factory unlocked code of 19h will be present. INHERENT DATA PROTECTION To avoid accidental erasure or programming of the device, the device is automatically reset to Read mode during power up. Additionally, the following design features protect the device from unintended data corruption. COMMAND COMPLETION Only after the successful completion of the specified command sets will the device begin its erase or program operation. If any command sequence is interrupted or given an invalid command, the device immediately returns to Read mode. LOW VCC WRITE INHIBIT The device refuses to accept any write command when Vcc is less than Vlko. This prevents data from spuriously being altered during power-up, power-down, or temporary power interruptions. The device automatically resets itself when Vcc is lower than Vlko and write cycles are ignored until Vcc is greater than Vlko. The system must provide proper signals on control pins after Vcc rises above Vlko to avoid unintentional program or erase operations. WRITE PULSE "GLITCH" PROTECTION CE#, WE#, OE# pulses shorter than 5ns are treated as glitches and will not be regarded as an effective write cycle. LOGICAL INHIBIT A valid write cycle requires both CE# and WE# at Vil with OE# at Vih. Write cycle is ignored when either CE# at Vih, WE# a Vih, or OE# at Vil. POWER-UP SEQUENCE Upon power up, the MX29LV320E T/B is placed in Read mode. Furthermore, program or erase operation will begin only after successful completion of specified command sequences.

P/N:PM1575 REV. 1.3, DEC. 19, 2013 22 MX29LV320E T/B COMMAND OPERATIONS (cont'd) AUTOMATIC PROGRAMMING OF THE MEMORY ARRAY The MX29LV320E T/B provides the user the ability to program the memory array in Byte mode or Word mode. As long as the users enters the correct cycle defined in the Table 3 (including 2 unlock cycles and the A0H program command), any byte or word data provided on the data lines by the system will automatically be programmed into the array at the specified location. After the program command sequence has been executed, the internal write state machine (WSM) automatically executes the algorithms and timings necessary for programming and verification, which includes generating suitable program pulses, checking cell threshold voltage margins, and repeating the program pulse if any cells do not pass verification or have low margins. The internal controller protects cells that do pass verification and margin tests from being over-programmed by inhibiting further program pulses to these passing cells as weaker cells continue to be programmed. With the internal WSM automatically controlling the programming process, the user only needs to enter the program command and data once. Programming will only change the bit status from "1" to "0". It is not possible to change the bit status from "0" to "1" by programming. This can only be done by an erase operation. Furthermore, the internal write verification only checks and detects errors in cases where a "1" is not successfully programmed to "0". Any commands written to the device during programming will be ignored except hardware reset, which will terminate the program operation after a period of time no more than Tready1. When the embedded program algorithm is complete or the program operation is terminated by a hardware reset, the device will return to Read mode. The typical chip program time at room temperature of the MX29LV320E T/B is less than 36 seconds. After the embedded program operation has begun, the user can check for completion by reading the following bits in the status register: Status In progress Finished Exceed time limit Q7*1 Q7# Q7 Q7# Q6*1 Toggling Stop toggling Toggling Q5 0 0 1 RY/BY# *2 0 1 0 *1: When an attempt is made to program a protected sector, the program operation will abort thus preventing any data changes in the protected sector. Q7 will output complement data and Q6 will toggle (briefly 1us or less) before aborting and returning the device to Read mode. *2: RY/BY# is an open drain output pin and should be connected to VCC through a high value pull-up resistor. ERASING THE MEMORY ARRAY There are two types of erase operations performed on the memory array -- Sector Erase and Chip Erase. In the Sector Erase operation, one or more selected sectors may be erased simultaneously. In the Chip Erase operation, the complete memory array is erased except for any protected sectors. P/N:PM1575 REV. 1.3, DEC. 19, 2013 23 MX29LV320E T/B COMMAND OPERATIONS (cont'd) SECTOR ERASE The sector erase operation is used to clear data within a sector by returning all of its memory locations to the "1" state. It requires six command cycles to initiate the erase operation. The first two cycles are "unlock cycles", the third is a configuration cycle, the fourth and fifth are also "unlock cycles", and the sixth cycle is the Sector Erase command. After the sector erase command sequence has been issued, an internal 50us time-out counter is started. Until this counter reaches zero, additional sector addresses and Sector Erase commands may be issued thus allowing multiple sectors to be selected and erased simultaneously. After the 50us time-out counter has expired, no new commands will be accepted and the embedded sector erase operation will begin. Note that the 50us timer-out counter is restarted after every erase command sequence. If the user enters any command other than Sector Erase or Erase Suspend during the time-out period, the erase operation will abort and the device will return to Read mode. After the embedded sector erase operation begins, all commands except Erase Suspend will be ignored. The only way to interrupt the operation is with an Erase Suspend command or with a hardware reset. The hardware reset will completely abort the operation and return the device to Read mode. The system can determine the status of the embedded sector erase operation by the following methods: Status Time-out period In progress Finished Exceeded time limit Q7 Q6 Q5 Q3 (note 1) Q2 0 0 1 0 Toggling Toggling Stop toggling Toggling 0 0 0 1 0 1 1 1 Toggling Toggling 1 Toggling RY/BY# (note 2) 0 0 1 0 Note : 1. The Q3 status bit is the time-out indicator. When Q3=0, the time-out counter has not yet reached zero and a new Sector Erase command may be issued to specify the address of another sector to be erased. When Q3=1, the time-out counter has expired and the Sector Erase operation has already begun. Erase Suspend is the only valid command that may be issued once the embedded erase operation is underway. 2. RY/BY# is an open drain output pin and should be connected to VCC through a high value pull-up resistor. 3. When an attempt is made to erase only protected sector(s), the program operation will abort thus preventing any data changes in the protected sector(s). Q7 will output zero and Q6 will toggle (briefly 100us or less) before aborting and returning the device to read mode. If unprotected sectors are also specified, however, they will be erased normally and the protected sector(s) will remain unchanged. 4. Q2 is a localized indicator showing a specified sector is undergoing erase operation or not. Q2 toggles when user reads at addresses where the sectors are actively being erased (in erase mode) or to be erased (in erase suspend mode). When a sector has been completely erased, Q2 stops toggling at the sector even when the device is still in erase operation for remaining selected sectors. At that circumstance, Q2 will still toggle when device is read at any other sector that remains to be erased. P/N:PM1575 REV. 1.3, DEC. 19, 2013 24 MX29LV320E T/B COMMAND OPERATIONS (cont'd) CHIP ERASE The Chip Erase operation is used erase all the data within the memory array. All memory cells containing a "0" will be returned to the erased state of "1". This operation requires 6 write cycles to initiate the action. The first two cycles are "unlock" cycles, the third is a configuration cycle, the fourth and fifth are also "unlock" cycles, and the sixth cycle initiates the chip erase operation. During the chip erase operation, no other software commands will be accepted, but if a hardware reset is received or the working voltage is too low, that chip erase will be terminated. After Chip Erase, the chip will automatically return to Read mode. The system can determine the status of the embedded chip erase operation by the following methods: Status In progress Finished Exceed time limit Q7 0 1 0 Q6 Toggling Stop toggling Toggling Q5 0 0 1 Q2 Toggling 1 Toggling RY/BY#*1 0 1 0 *1: RY/BY# is an open drain output pin and should be connected to VCC through a high value pull-up resistor. SECTOR ERASE SUSPEND After beginning a sector erase operation, Erase Suspend is the only valid command that may be issued. If system issues an Erase Suspend command during the 50us time-out period following a Sector Erase command, the time-out period will terminate immediately and the device will enter Erase-Suspended Read mode. If the system issues an Erase Suspend command after the sector erase operation has already begun, the device will not enter Erase-Suspended Read mode until Tready1 time has elapsed. The system can determine if the device has entered the Erase-Suspended Read mode through Q6, Q7, and RY/BY#. After the device has entered Erase-Suspended Read mode, the system can read or program any sector(s) except those being erased by the suspended erase operation. Reading any sector being erased or programmed will return the contents of the status register. Whenever a suspend command is issued, user must issue a resume command and check Q6 toggle bit status, before issue another erase command. The system can use the status register bits shown in the following table to determine the current state of the device: Status Q7 Erase suspend read in erase suspended sector 1 Erase suspend read in non-erase suspended sector Erase suspend program in non-erase suspended sector Data Q7# Q6 No toggle Data Toggle Q5 Q3 Q2 RY/BY# 0 N/A Toggle 1 Data 0 Data N/A Data N/A 1 0 When the device has suspended erasing, user can execute the command sets except sector erase and chip erase, such as read silicon ID, sector protect verify, program, CFI query and erase resume. P/N:PM1575 REV. 1.3, DEC. 19, 2013 25 MX29LV320E T/B COMMAND OPERATIONS (cont'd) SECTOR ERASE RESUME The sector Erase Resume command is valid only when the device is in Erase-Suspended Read mode. After erase resumes, the user can issue another Ease Suspend command, but there should be a 4ms interval between Ease Resume and the next Erase Suspend command. If the user enters an infinite suspend-resume loop, or suspend-resume exceeds 1024 times, erase times will increase dramatically. AUTOMATIC SELECT OPERATIONS When the device is in Read mode, Erase-Suspended Read mode, or CFI mode, the user can issue the Automatic Select command shown in Table 3 (two unlock cycles followed by the Automatic Select command 90h) to enter Automatic Select mode. After entering Automatic Select mode, the user can query the Manufacturer ID, Device ID, Security Sector locked status, or Sector-Group protected status multiple times without issuing a new Automatic Select command. While In Automatic Select mode, issuing a Reset command (F0h) will return the device to Read mode (or EaseSuspended Read mode if Erase-Suspend was active). Another way to enter Automatic Select mode is to use one of the bus operations shown in Table 2-2. BUS OPERATION. After the high voltage (Vhv) is removed from the A9 pin, the device will automatically return to Read mode or Erase-Suspended Read mode. AUTOMATIC SELECT COMMAND SEQUENCE Automatic Select mode is used to access the manufacturer ID, device ID and to verify whether or not secured silicon is locked and whether or not a sector is protected. The automatic select mode has four command cycles. The first two are unlock cycles, and followed by a specific command. The fourth cycle is a normal read cycle, and user can read at any address any number of times without entering another command sequence. The Reset command is necessary to exit the Automatic Select mode and back to read array. The following table shows the identification code with corresponding address. Manufacturer ID Device ID Secured Silicon Sector Protect Verify Word Byte Word Byte Word Byte Word Byte Address (Hex) X00 X00 X01 X02 X03 X06 (Sector address) X 02 (Sector address) X 04 Data (Hex) C2 C2 22A7/22A8 A7/A8 99/19 99/19 00/01 00/01 Representation Top/Bottom Boot Sector Top/Bottom Boot Sector Factory locked/unlocked Factory locked/unlocked Unprotected/protected Unprotected/protected After entering automatic select mode, no other commands are allowed except the reset command. P/N:PM1575 REV. 1.3, DEC. 19, 2013 26 MX29LV320E T/B COMMAND OPERATIONS (cont'd) READ MANUFACTURER ID OR DEVICE ID The Manufacturer ID (identification) is a unique hexadecimal number assigned to each manufacturer by the JEDEC committee. Each company has its own manufacturer ID, which is different from the ID of all other companies. The number assigned to Macronix is C2h. The Device ID is a unique hexadecimal number assigned by the manufacturer for each one of the flash devices made by that manufacturer. The above two ID types are stored in a 16-bit register on the flash device -- eight bits for each ID. This register is normally read by the user or by the programming machine to identify the manufacturer and the specific device. After entering Automatic Select mode, performing a read operation with A1 & A0 held LOW will cause the device to output the Manufacturer ID on the Data I/O (Q7 to Q0) pins. Performing a read operation with A1 LOW and A0 HIGH will cause the device to output the Device ID. SECURITY SECTOR LOCK STATUS After entering Automatic Select mode, the customer can check the lock status of the Security Sector by performing a read operations with A0 and A1 held HIGH. If the code 99h is read from data pins Q7 to Q0, the sector has been locked at the factory. If the code 19h is read, the sector has not been locked at the factory. VERIFY SECTOR GROUP PROTECTION After entering Automatic Select mode, performing a read operation with A1 held HIGH and A0 held LOW and the address of the sector to be checked applied to A20 to A12, data bit Q0 will indicate the protected status of the addressed sector. If Q0 is HIGH, the sector is protected. Conversely, if Q0 is LOW, the sector is unprotected. SECURITY SECTOR FLASH MEMORY REGION The Security Sector region is an extra OTP memory space of 256Bytes (128Words) in length. The Security Sector can be locked by the factory prior to shipping, or it can be locked by the customer later. In factory-locked device, security sector region is protected when shipped from factory and the security silicon sector indicator bit, Q7 (at autoselect address 03h) is set to "1". In customer lockable device, security sector region is unprotected when shipped from factory and the security silicon indicator bit is set to "0". FACTORY LOCKED: SECURITY SECTOR PROGRAMMED AND PROTECTED AT THE FACTORY In a factory locked device, the Security Sector is permanently locked before shipping from the factory. The device will have a 16-byte (8-word) ESN in the security region. In bottom boot devices, the ESN occupies addresses 00000h to 0000Fh in byte mode or 00000h to 00007h in word mode. In top boot devices, the ESN occupies addresses 3F0000h to 3F000Fh in byte mode or 1F8000h to 1F8007h in word mode. P/N:PM1575 REV. 1.3, DEC. 19, 2013 27 MX29LV320E T/B COMMAND OPERATIONS (cont'd) CUSTOMER LOCKABLE: SECURITY SECTOR NOT PROGRAMMED OR PROTECTED AT THE FACTORY When the security feature is not required, the Security Sector can provide an extra sector of memory. Two methods are available for protecting the Security Sector. Note that once the Security Sector is protected, there is NO way to unprotect it and its contents can no longer be altered. The first protection method requires writing the three-cycle Enter Security Region command followed by the use of the Sector-Group protect algorithm as illustrated in Figure 14 with the following exception: the RESET# pin may be at either Vih or Vhv. Unlike normal Sector-Groups, which do require Vhv on the RESET# pin, the Security Sector may be permanently locked in-circuit without the use of high voltage. The second protection method also uses the three-cycle Enter Security Region command, but uses bus operations that applies Vhv to the A9 and OE# pins with A6, CE#, and WE# held LOW and the SA address applied to A20 to A12. The protection operation begins at the falling edge of WE# and terminates at the rising edge. Contact Macronix for more details on using this method. After the Security Sector is locked and verified, the system must write an Exit Security Sector Region command, go through a power cycle, or issue a hardware reset to return the device to read normal array mode. ENTER AND EXIT SECURITY SECTOR The device allows the user to access the extra 256-Byte sector identified as the Security Sector, which may contain a random, 128-bits electronic serial number (ESN), or it may contain user data. To access the Security Sector, the user must issue a three-cycle "Enter Security Sector" command sequence. To exit the Security Sector and return to normal operation, the user issues the four-cycle "Exit Security Sector" command. Before issuing the "Exit Security Sector" command, please ensure the entering of security sector region. P/N:PM1575 REV. 1.3, DEC. 19, 2013 28 MX29LV320E T/B COMMAND OPERATIONS (cont'd) RESET OPERATION In the following situations, executing reset command will reset device back to Read mode: • • • • • • • • Among erase command sequence (before the full command set is completed) Sector erase time-out period Erase fail (while Q5 is high) Among program command sequence (before the full command set is completed, erase-suspended program included) Program fail (while Q5 is high, and erase-suspended program fail is included) Read silicon ID mode Sector protect verify CFI mode While device is at the status of program fail or erase fail (Q5 is high), user must issue reset command to reset device back to read array mode. While the device is in read silicon ID mode, sector protect verify or CFI mode, user must issue reset command to reset device back to read array mode. When the device is in the progress of programming (not program fail) or erasing (not erase fail), device will ignore reset command. P/N:PM1575 REV. 1.3, DEC. 19, 2013 29 MX29LV320E T/B COMMON FLASH MEMORY INTERFACE (CFI) MODE QUERY COMMAND AND COMMAND FLASH MEMORY INTERFACE (CFI) MODE MX29LV320E T/B features CFI mode. Host system can retrieve the operating characteristics, structure and vendor-specified information such as identifying information, memory size, byte/word configuration, operating voltages and timing information of this device by CFI mode. The device enters the CFI Query mode when the system writes the CFI Query command, 98H, to address 55h/AAh (depending on Word/Byte mode) any time the device is ready to read array data. The system can read CFI information at the addresses given in Table 4. Once user enters CFI query mode, user can not issue any other commands except reset command. The reset command is required to exit CFI mode and go back to the mode before entering CFI. The system can write the CFI Query command only when the device is in read mode, erase suspend, standby mode or automatic select mode. The CFI unused area is Macronix's reserved. Table 4-1.
