MXIC's Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The MX29LV033C is packaged in 40-pin TSOP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers. MXIC's Flash memories augment EPROM functionality with in-circuit electrical erasure and programming. The MX29LV033C uses a command register to manage this functionality. MXIC Flash technology reliably stores memory contents even after 100,000 erase and program cycles. The MXIC cell is designed to optimize the erase and program mechanisms. In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and programming operations produces reliable cycling. The MX29LV033C uses a 2.7V to 3.6V VCC The standard MX29LV033C offers access time as fast as 70ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29LV033C has separate chip enable (CE#) and output enable (OE#) controls. P/N:PM1189 REV. 0.02, JUL. 21, 2005 1 MX29LV033C supply to perform the High Reliability Erase and auto Program/Erase algorithms. matically programs the specified sector(s) prior to electrical erase. The timing and verification of electrical erase are controlled internally within the device. The highest degree of latch-up protection is achieved with MXIC's proprietary non-epi process. Latch-up protection is proved for stresses up to 100 milliamps on address and data pin from -1V to VCC + 1V. AUTOMATIC ERASE ALGORITHM MXIC's Automatic Erase algorithm requires the user to write commands to the command register using standard microprocessor write timings. The device will automatically pre-program and verify the entire array. Then the device automatically times the erase pulse width, provides the erase verification, and counts the number of sequences. A status bit toggling between consecutive read cycles provides feedback to the user as to the status of the programming operation. AUTOMATIC PROGRAMMING The MX29LV033C is byte programmable using the Automatic Programming algorithm. The Automatic Programming algorithm makes the external system do not need to have time out sequence nor to verify the data programmed. The typical chip programming time at room temperature of the MX29LV033C is less than 36 seconds. Register contents serve as inputs to an internal statemachine which controls the erase and programming circuitry. During write cycles, the command register internally latches address and data needed for the programming and erase operations. During a system write cycle, addresses are latched on the falling edge, and data are latched on the rising edge of WE# . AUTOMATIC PROGRAMMING ALGORITHM MXIC's Automatic Programming algorithm require the user to only write program set-up commands (including 2 unlock write cycle and A0H) and a program command (program data and address). The device automatically times the programming pulse width, provides the program verification, and counts the number of sequences. A status bit similar to DATA# polling and a status bit toggling between consecutive read cycles, provide feedback to the user as to the status of the programming operation. MXIC's Flash technology combines years of EPROM experience to produce the highest levels of quality, reliability, and cost effectiveness. The MX29LV033C electrically erases all bits simultaneously using Fowler-Nordheim tunneling. The bytes are programmed by using the EPROM programming mechanism of hot electron injection. During a program cycle, the state-machine will control the program sequences and command register will not respond to any command set. During a Sector Erase cycle, the command register will only respond to Erase Suspend command. After Erase Suspend is completed, the device stays in read mode. After the state machine has completed its task, it will allow the command register to respond to its full command set. AUTOMATIC CHIP ERASE The entire chip is bulk erased using 50 ms erase pulses according to MXIC's Automatic Chip Erase algorithm. Typical erasure at room temperature is accomplished in less than 35 seconds. The Automatic Erase algorithm automatically programs the entire array prior to electrical erase. The timing and verification of electrical erase are controlled internally within the device. AUTOMATIC SECTOR ERASE The MX29LV033C is sector(s) erasable using MXIC's Auto Sector Erase algorithm. Sector erase modes allow sectors of the array to be erased in one erase cycle. The Automatic Sector Erase algorithm auto- P/N:PM1189 REV. 0.02, JUL. 21, 2005 2 MX29LV033C PIN CONFIGURATION 40 TSOP A16 A15 A14 A13 A12 A11 A9 A8 WE# RESET# ACC RY/BY# A18 A7 A6 A5 A4 A3 A2 A1 LOGIC SYMBOL 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 MX29LV033C 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 A17 VSS A20 A19 A10 Q7 Q6 Q5 Q4 VCC VCC A21 Q3 Q2 Q1 Q0 OE# VSS CE# A0 22 8 A0-A21 Q0-Q7 CE# OE# WE# RESET# RY/BY# ACC PIN DESCRIPTION SYMBOL A0~A21 Q0~Q7 CE# WE# OE# RESET# RY/BY# VCC ACC VSS NC PIN NAME Address Input 8 Data Inputs/Outputs Chip Enable Input Write Enable Input Output Enable Input Hardware Reset Pin, Active Low Read/Busy Output +3.3V single power supply Hardware Acceleration Pin Device Ground Pin Not Connected Internally P/N:PM1189 REV. 0.02, JUL. 21, 2005 3 MX29LV033C BLOCK DIAGRAM WRITE CE# OE# WE# CONTROL PROGRAM/ERASE STATE INPUT LOGIC HIGH VOLTAGE MACHINE (WSM) LATCH A0-A21 BUFFER FLASH REGISTER ARRAY ARRAY Y-DECODER AND X-DECODER ADDRESS STATE MX29LV033C Y-PASS GATE SOURCE HV COMMAND DATA DECODER SENSE AMPLIFIER PGM DATA HV COMMAND DATA LATCH PROGRAM DATA LATCH Q0-Q7 I/O BUFFER P/N:PM1189 REV. 0.02, JUL. 21, 2005 4 MX29LV033C SECTOR (GROUP) STRUCTURE Group Sector A21 A20 A19 A18 A17 A16 Address Range(in hexadecimal) SGA0 SA0 0 0 0 0 0 0 000000-00FFFF SGA1 SA1 0 0 0 0 0 1 010000-01FFFF SGA1 SA2 0 0 0 0 1 0 020000-02FFFF SGA1 SA3 0 0 0 0 1 1 030000-03FFFF SGA2 SA4 0 0 0 1 0 0 040000-04FFFF SGA2 SA5 0 0 0 1 0 1 050000-05FFFF SGA2 SA6 0 0 0 1 1 0 060000-06FFFF SGA2 SA7 0 0 0 1 1 1 070000-07FFFF SGA3 SA8 0 0 1 0 0 0 080000-08FFFF SGA3 SA9 0 0 1 0 0 1 090000-09FFFF SGA3 SA10 0 0 1 0 1 0 0A0000-0AFFFF SGA3 SA11 0 0 1 0 1 1 0B0000-0BFFFF SGA4 SA12 0 0 1 1 0 0 0C0000-0CFFFF SGA4 SA13 0 0 1 1 0 1 0D0000-0DFFFF SGA4 SA14 0 0 1 1 1 0 0E0000-0EFFFF SGA4 SA15 0 0 1 1 1 1 0F0000-0FFFFF SGA5 SA16 0 1 0 0 0 0 100000-10FFFF SGA5 SA17 0 1 0 0 0 1 110000-11FFFF SGA5 SA18 0 1 0 0 1 0 120000-12FFFF SGA5 SA19 0 1 0 0 1 1 130000-13FFFF SGA6 SA20 0 1 0 1 0 0 140000-14FFFF SGA6 SA21 0 1 0 1 0 1 150000-15FFFF SGA6 SA22 0 1 0 1 1 0 160000-16FFFF SGA6 SA23 0 1 0 1 1 1 170000-17FFFF SGA7 SA24 0 1 1 0 0 0 180000-18FFFF SGA7 SA25 0 1 1 0 0 1 190000-19FFFF SGA7 SA26 0 1 1 0 1 0 1A0000-1AFFFF SGA7 SA27 0 1 1 0 1 1 1B0000-1BFFFF SGA8 SA28 0 1 1 1 0 0 1C0000-1CFFFF SGA8 SA29 0 1 1 1 0 1 1D0000-1DFFFF SGA8 SA30 0 1 1 1 1 0 1E0000-1EFFFF SGA8 SA31 0 1 1 1 1 1 1F0000-1FFFFF SGA9 SA32 1 0 0 0 0 0 200000-20FFFF SGA9 SA33 1 0 0 0 0 1 210000-21FFFF SGA9 SA34 1 0 0 0 1 0 220000-22FFFF SGA9 SA35 1 0 0 0 1 1 230000-23FFFF SGA10 SA36 1 0 0 1 0 0 240000-24FFFF SGA10 SA37 1 0 0 1 0 1 250000-25FFFF SGA10 SA38 1 0 0 1 1 0 260000-26FFFF SGA10 SA39 1 0 0 1 1 1 270000-27FFFF P/N:PM1189 REV. 0.02, JUL. 21, 2005 5 MX29LV033C Group Sector A21 A20 A19 A18 A17 A16 Address Range(in hexadecimal) SGA11 SA40 1 0 1 0 0 0 280000-28FFFF SGA11 SA41 1 0 1 0 0 1 290000-29FFFF SGA11 SA42 1 0 1 0 1 0 2A0000-2AFFFF SGA11 SA43 1 0 1 0 1 1 2B0000-2BFFFF SGA12 SA44 1 0 1 1 0 0 2C0000-2CFFFF SGA12 SA45 1 0 1 1 0 1 2D0000-2DFFFF SGA12 SA46 1 0 1 1 1 0 2E0000-2EFFFF SGA12 SA47 1 0 1 1 1 1 2F0000-2FFFFF SGA13 SA48 1 1 0 0 0 0 300000-30FFFF SGA13 SA49 1 1 0 0 0 1 310000-31FFFF SGA13 SA50 1 1 0 0 1 0 320000-32FFFF SGA13 SA51 1 1 0 0 1 1 330000-33FFFF SGA14 SA52 1 1 0 1 0 0 340000-34FFFF SGA14 SA53 1 1 0 1 0 1 350000-35FFFF SGA14 SA54 1 1 0 1 1 0 360000-36FFFF SGA14 SA55 1 1 0 1 1 1 370000-37FFFF SGA15 SA56 1 1 1 0 0 0 380000-38FFFF SGA15 SA57 1 1 1 0 0 1 390000-39FFFF SGA15 SA58 1 1 1 0 1 0 3A0000-3AFFFF SGA15 SA59 1 1 1 0 1 1 3B0000-3BFFFF SGA16 SA60 1 1 1 1 0 0 3C0000-3CFFFF SGA16 SA61 1 1 1 1 0 1 3D0000-3DFFFF SGA16 SA62 1 1 1 1 1 0 3E0000-3EFFFF SGA17 SA63 1 1 1 1 1 1 3F0000-3FFFFF P/N:PM1189 REV. 0.02, JUL. 21, 2005 6 MX29LV033C Table 1.

CE# is the power control and selects the device. OE# is the output control and gates array data to the output pins. WE# should remain at VIH. The device offers accelerated program operations through the ACC function. If the system asserts VHH on ACC pin, the device will provide the fast programming time to user. This function is primarily intended to allow faster manufacturing throughput during production. Removing VHH from the ACC pin returns the device to normal operation. Note that the ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid address on the device address inputs produce valid data on the device data outputs. The device remains enabled for read access until the command register contents are altered. STANDBY MODE MX29LV033C can be set into Standby mode with two different approaches. One is using both CE# and RESET# pins and the other one is using RESET# pin only. WRITE COMMANDS/COMMAND SEQUENCES When using both pins of CE# and RESET#, a CMOS Standby mode is achieved with both pins held at VCC ± 0.3V. Under this condition, the current consumed is less than 0.2uA (typ.). If both of the CE# and RESET# are held at VIH, but not within the range of VCC ± 0.3V, the device will still be in the standby mode, but the standby current will be larger. During Auto Algorithm operation, VCC active current (Icc2) is required even CE# = "H" until the operation is completed. The device can be read with standard access time (tCE) from either of these standby modes. To program data to the device or erase sectors of memory , the system must drive WE# and CE# to VIL, and OE# to VIH. An erase operation can erase one sector, multiple sectors , or the entire device. Table indicates the address space that each sector occupies. A "sector address" consists of the address bits required to uniquely select a sector. The Writing specific address and data commands or sequences into the command register initiates device operations. Table 1 defines the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence resets the device to reading array data. Section has details on erasing a sector or the entire chip, or suspending/resuming the erase operation. When using only RESET#, a CMOS standby mode is achieved with RESET# input held at VSS ± 0.3V, Under this condition the current is consumed less than 1uA (typ.). Once the RESET# pin is taken high, the device is back to active without recovery delay. In the standby mode the outputs are in the high impedance state, independent of the OE# input. After the system writes the auto-select command sequence, the device enters the auto-select mode. The system can then read auto-select codes from the internal register (which is separate from the memory array) on Q7-Q0. Standard read cycle timings apply in this mode. Refer to the Auto-select Mode and Auto-select Command Sequence section for more information. MX29LV033C is capable to provide the Automatic Standby Mode to restrain power consumption during readout of data. This mode can be used effectively with an application requested low power consumption such as handy terminals. ICC2 in the DC Characteristics table represents the active current specification for the write mode. The "AC Characteristics" section contains timing specification table and timing diagrams for write operations. To active this mode, MX29LV033C automatically switch themselves to low power mode when MX29LV033C addresses remain stable during access time of tACC+30ns. It is not necessary to control CE#, WE#, and OE# on the mode. Under the mode, the current consumed is typically 0.2uA (CMOS level). P/N:PM1189 REV. 0.02, JUL. 21, 2005 8 MX29LV033C OUTPUT DISABLE 12V) A6 = VIL and CE# = VIL. (see Table 2) Programming of the protection circuitry begins on the falling edge of the WE# pulse and is terminated on the rising edge. Please refer to sector group protect algorithm and waveform. With the OE# input at a logic high level (VIH), output from the devices are disabled. This will cause the output pins to be in a high impedance state. MX29LV033C also provides another method. Which requires VID on the RESET# only. This method can be implemented either in-system or via programming equipment. This method uses standard microprocessor bus cycle timing. RESET# OPERATION The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity To verify programming of the protection circuitry, the programming equipment must force VID on address pin A9 ( with CE# and OE# at VIL and WE# at VIH). When A1=1, it will produce a logical "1" code at device output Q0 for a protected sector. Otherwise the device will produce 00H for the unprotected sector. In this mode, the addresses, except for A1, are don't care. Address locations with A1 = VIL are reserved to read manufacturer and device codes. (Read Silicon ID) Current is reduced for the duration of the RESET# pulse. When RESET# is held at VSS±0.3V, the device draws CMOS standby current (ICC4). If RESET is held at VIL but not within VSS±0.3V, the standby current will be greater. It is also possible to determine if the group is protected in the system by writing a Read Silicon ID command. Performing a read operation with A1=VIH, it will produce a logical "1" at Q0 for the protected sector. The RESET# pin may be tied to system reset circuitry. A system reset would that also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory. CHIP UNPROTECTED OPERATION The MX29LV033C also features the chip unprotected mode, so that all sectors are unprotected after chip unprotected is completed to incorporate any changes in the code. It is recommended to protect all sectors before activating chip unprotected mode. If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a "0" (busy) until the internal reset operation is complete, which requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/BY# to determine whether the reset operation is complete. If RESET# is asserted when a program or erase operation is completed within a time of tREADY (not during Embedded Algorithms). The system can read data tRH after the RESET# pin returns to VIH. To activate this mode, the programming equipment must force VID on control pin OE# and address pin A9. The CE# pins must be set at VIL. Pins A6 must be set to VIH.(see Table 2) Refer to chip unprotected algorithm and waveform for the chip unprotected algorithm. The unprotected mechanism begins on the falling edge of the WE# pulse and is terminated on the rising edge. Refer to the AC Characteristics tables for RESET# parameters and to Figure 3 for the timing diagram. MX29LV033C also provides another method. Which requires VID on the RESET# only. This method can be implemented either in-system or via programming equipment. This method uses standard microprocessor bus cycle timing. SECTOR GROUP PROTECT OPERATION The MX29LV033C features hardware sector group protection. This feature will disable both program and erase operations for these sector group protected. To activate this mode, the programming equipment must force VID on address pin A9 and control pin OE#, (suggest VID = It is also possible to determine if the chip is unprotected in the system by writing the Read Silicon ID command. P/N:PM1189 REV. 0.02, JUL. 21, 2005 9 MX29LV033C Performing a read operation with A1=VIH, it will produce 00H at data outputs (Q0-Q7) for an unprotected sector. It is noted that all sectors are unprotected after the chip unprotected algorithm is completed. device resides in the target system. PROM programmers typically access signature codes by raising A9 to a high voltage. However, multiplexing high voltage onto address lines is not generally desired system design practice. TEMPORARY SECTOR GROUP UNPROTECTED OPERATION MX29LV033C provides hardware method to access the silicon ID read operation. Which method requires VID on A9 pin, VIL on CE#, OE#, A6, and A1 pins. Which apply VIL on A0 pin, the device will output MXIC's manufacture code of C2H. Which apply VIH on A0 pin, the device will output MX29LV033C device code of A3H. This feature allows temporary unprotected of previously protected sector to change data in-system. The Temporary Sector Unprotected mode is activated by setting the RESET# pin to VID(11.5V-12.5V). During this mode, formerly protected sectors can be programmed or erased as unprotected sector. Once VID is remove from the RESET# pin, all the previously protected sectors are protected again. VERIFY SECTOR GROUP PROTECT STATUS OPERATION MX29LV033C provides hardware method for sector group protect status verify. Which method requires VID on A9 pin, VIH on WE# and A1 pins, VIL on CE#, OE#, A6, and A0 pins, and sector address on A16 to A21 pins. Which the identified sector is protected, the device will output 01H. Which the identified sector is not protect, the device will output 00H.

The MX29LV033C is designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transition. During power up the device automatically resets the state machine in the Read mode. In addition, with its control register architecture, alteration of the memory contents only occurs after successful completion of specific command sequences. The device also incorporates several features to prevent inadvertent write cycles resulting from VCC power-up and power-down transition or system noise. POWER SUPPLY DECOUPLING In order to reduce power switching effect, each device should have a 0.1uF ceramic capacitor connected between its VCC and GND. LOW VCC WRITE INHIBIT When VCC is less than VLKO the device does not accept any write cycles. This protects data during VCC power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control pins to prevent unintentional write when VCC is greater than VLKO. WRITE PULSE "GLITCH" PROTECTION Noise pulses of less than 5ns(typical) on CE# or WE# will not initiate a write cycle. LOGICAL INHIBIT Writing is inhibited by holding any one of OE# = VIL, CE# = VIH or WE# = VIH. To initiate a write cycle CE# and WE# must be a logical zero while OE# is a logical one. POWER-UP SEQUENCE The MX29LV033C powers up in the Read only mode. In addition, the memory contents may only be altered after successful completion of the predefined command sequences.

READING ARRAY DATA array data (also applies to programming in Erase Suspend mode). Once programming begins, however, the device ignores reset commands until the operation is complete. The device is automatically set to reading array data after device power-up. No commands are required to retrieve data. The device is also ready to read array data after completing an Automatic Program or Automatic Erase algorithm. The reset command may be written between the sequence cycles in an SILICON ID READ command sequence. Once in the SILICON ID READ mode, the reset command must be written to return to reading array data (also applies to SILICON ID READ during Erase Suspend). After the device accepts an Erase Suspend command, the device enters the Erase Suspend mode. The system can read array data using the standard read timings, except that if it reads at an address within erase-suspended sectors, the device outputs status data. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See Erase Suspend/Erase Resume Commands” for more information on this mode. The system must issue the reset command to re-enable the device for reading array data if Q5 goes high, or while in the auto-select mode. See the "Reset Command" section, next. If Q5 goes high during a program or erase operation, writing the reset command returns the device to reading array data (also applies during Erase Suspend). SILICON ID READ COMMAND SEQUENCE The SILICON ID READ command sequence allows the host system to access the manufacturer and devices codes, and determine whether or not a sector is protected. Table 2 shows the address and data requirements. This method is an alternative to that shown in Table 1, which is intended for PROM programmers and requires VID on address bit A9. RESET COMMAND Writing the reset command to the device resets the device to reading array data. Address bits are don't care for this command. The SILICON ID READ command sequence is initiated by writing two unlock cycles, followed by the SILICON ID READ command. The device then enters the SILICON ID READ mode, and the system may read at any address any number of times, without initiating another command sequence. A read cycle at address XX00h retrieves the manufacturer code. A read cycle at address XX01h returns the device code. A read cycle containing a sector address (SA) and the address 02h returns 01h if that sector is protected, or 00h if it is unprotected. Refer The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the device to reading array data. Once erasure begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the device to reading P/N:PM1189 REV. 0.02, JUL. 21, 2005 13 MX29LV033C The Byte Program command sequence should be reinitiated once the device has reset to reading array data, to ensure data integrity. to Table for valid sector addresses. The system must write the reset command to exit the auto-select mode and return to reading array data. Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from a "0" back to a "1". Attempting to do so may halt the operation and set Q5 to "1", or cause the Data# Polling algorithm to indicate the operation was successful. However, a succeeding read will show that the data is still "0". Only erase operations can convert a "0" to a "1". BYTE PROGRAM COMMAND SEQUENCE The device programs one byte of data for each program operation. The command sequence requires four bus cycles, and is initiated by writing two unlock write cycles, followed by the program set-up command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further controls or timings. The device automatically generates the program pulses and verifies the programmed cell margin. Table 1 shows the address and data requirements for the byte program command sequence. SETUP AUTOMATIC CHIP/SECTOR ERASE Chip erase is a six-bus cycle operation. There are two "unlock" write cycles. These are followed by writing the "set-up" command 80H. Two more "unlock" write cycles are then followed by the chip erase command 10H, or the sector erase command 30H. When the Embedded Program algorithm is complete, the device then returns to reading array data and addresses are no longer latched. The system can determine the status of the program operation by using Q7, Q6, or RY/BY#. See "Write Operation Status" for information on these status bits. The MX29LV033C contains a Silicon-ID-Read operation to supplement traditional PROM programming methodology. The operation is initiated by writing the read silicon ID command sequence into the command register. Following the command write, a read cycle with A1=VIL,A0=VIL retrieves the manufacturer code of C2H. A read cycle with A1=VIL, A0=VIH returns the device code of A3H for MX29LV033C. Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hardware reset immediately terminates the programming operation. TABLE 3.

Note that a hardware reset during the chip erase operation immediately terminates the operation. The Chip Erase command sequence should be reinitiated once the device has returned to reading array data, to ensure data integrity. The device does not require the system to preprogram prior to erase. The Automatic Erase algorithm automatically preprogram and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. Table 2 shows the address and data requirements for the chip erase command sequence. The system can determine the status of the erase operation by using Q7, Q6, Q2, or RY/BY#. See "Write Operation Status" for information on these status bits. When the Automatic Erase algorithm is complete, the device returns to reading array data and addresses are no longer Any commands written to the chip during the Automatic P/N:PM1189 REV. 0.02, JUL. 21, 2005 14 MX29LV033C latched. ERASE SUSPEND Figure 4 illustrates the algorithm for the erase operation. See the Erase/Program Operations tables in "AC Characteristics" for parameters, and to Figure 16 for timing diagrams. This command only has meaning while the state machine is executing Automatic Sector Erase operation, and therefore will only be responded during Automatic Sector Erase operation. When the Erase Suspend command is issued during the sector erase operation, the device requires a maximum 20us to suspend the sector erase operation. However, When the Erase Suspend command is written during the sector erase time-out, the device immediately terminates the time-out period and suspends the erase operation. After this command has been executed, the command register will initiate erase suspend mode. The state machine will return to read mode automatically after suspend is ready. At this time, state machine only allows the command register to respond to the Erase Resume, program data to, or read data from any sector not selected for erasure. SECTOR ERASE COMMANDS The Automatic Sector Erase does not require the device to be entirely pre-programmed prior to executing the Automatic Set-up Sector Erase command and Automatic Sector Erase command. Upon executing the Automatic Sector Erase command, the device will automatically program and verify the sector(s) memory for an all-zero data pattern. The system is not required to provide any control or timing during these operations. When the sector(s) is automatically verified to contain an all-zero pattern, a self-timed sector erase and verify begin. The erase and verify operations are complete when the data on Q7 is "1" and the data on Q6 stops toggling for two consecutive read cycles, at which time the device returns to the Read mode. The system is not required to provide any control or timing during these operations. The system can determine the status of the program operation using the Q7 or Q6 status bits, just as in the standard program operation. After an erase-suspend program operation is complete, the system can once again read array data within non-suspended blocks. When using the Automatic Sector Erase algorithm, note that the erase automatically terminates when adequate erase margin has been achieved for the memory array (no erase verification command is required). Sector erase is a six-bus cycle operation. There are two "unlock" write cycles. These are followed by writing the set-up command 80H. Two more "unlock" write cycles are then followed by the sector erase command 30H. The sector address is latched on the falling edge of WE# or CE#, whichever happens later , while the command (data) is latched on the rising edge of WE# or CE#, whichever happens first. Sector addresses selected are loaded into internal register on the sixth falling edge of WE# or CE#, whichever happens later. Each successive sector load cycle started by the falling edge of WE# or CE#, whichever happens later must begin within 50us from the rising edge of the preceding WE# or CE#, whichever happens first. Otherwise, the loading period ends and internal auto sector erase cycle starts. (Monitor Q3 to determine if the sector erase timer window is still open, see section Q3, Sector Erase Timer.) Any command other than Sector Erase(30H) or Erase Suspend(B0H) during the time-out period resets the device to read mode. This command will cause the command register to clear the suspend state and return back to Sector Erase mode but only if an Erase Suspend command was previously issued. Erase Resume will not have any effect in all other conditions. Another Erase Suspend command can be written after the chip has resumed erasing. ERASE RESUME P/N:PM1189 REV. 0.02, JUL. 21, 2005 15 MX29LV033C WRITE OPERATION STATUS The device provides several bits to determine the status of a write operation: Q2, Q3, Q5, Q6, Q7, and RY/BY#. Table 10 and the following subsections describe the functions of these bits. Q7, RY/BY#, and Q6 each offer a method for determining whether a program or erase operation is complete or in progress. These three bits are discussed first. Table 4. Write Operation Status Status Byte Program in Auto Program Algorithm Auto Erase Algorithm Erase Suspend Read (Erase Suspended Sector) Q7 Note1 Q6 Q5 Note2 Q3 Q2 RY/BY# Q7# Toggle 0 N/A No Toggle 0 0 Toggle 0 1 Toggle 0 1 No Toggle 0 N/A Toggle 1 Data Data Data Data 1 Q7# Toggle 0 N/A N/A 0 Q7# Toggle 1 N/A No Toggle 0 0 Toggle 1 1 Toggle 0 Q7# Toggle 1 N/A N/A 0 In Progress Erase Suspended Mode Erase Suspend Read Data (Non-Erase Suspended Sector) Erase Suspend Program Byte Program in Auto Program Algorithm Exceeded Time Limits Auto Erase Algorithm Erase Suspend Program Notes: 1. Performing successive read operations from the erase-suspended sector will cause Q2 to toggle. 1. Performing successive read operations from any address will cause Q6 to toggle. 3. Reading the byte address being programmed while in the erase-suspend program mode will indicate logic "1" at the Q2 bit. However, successive reads from the erase-suspended sector will cause Q2 to toggle. P/N:PM1189 REV. 0.02, JUL. 21, 2005 16 MX29LV033C Q7: Data# Polling after the rising edge of the final WE# or CE#, whichever happens first pulse in the command sequence (prior to the program or erase operation), and during the sector time-out. The Data# Polling bit, Q7, indicates to the host system whether an Automatic Algorithm is in progress or completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the program or erase command sequence. During an Automatic Program or Erase algorithm operation, successive read cycles to any address cause Q6 to toggle. The system may use either OE# or CE# to control the read cycles. When the operation is complete, Q6 stops toggling. During the Automatic Program algorithm, the device outputs on Q7 the complement of the datum programmed to Q7. This Q7 status also applies to programming during Erase Suspend. When the Automatic Program algorithm is complete, the device outputs the datum programmed to Q7. The system must provide the program address to read valid status information on Q7. If a program address falls within a protected sector, Data# Polling on Q7 is active for approximately 1 us, then the device returns to reading array data. After an erase command sequence is written, if all sectors selected for erasing are protected, Q6 toggles for 100us and returns to reading array data. If not all selected sectors are protected, the Automatic Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use Q6 and Q2 together to determine whether a sector is actively erasing or is erase suspended. When the device is actively erasing (that is, the Automatic Erase algorithm is in progress), Q6 toggling. When the device enters the Erase Suspend mode, Q6 stops toggling. However, the system must also use Q2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use Q7. During the Automatic Erase algorithm, Data# Polling produces a "0" on Q7. When the Automatic Erase algorithm is complete, or if the device enters the Erase Suspend mode, Data# Polling produces a "1" on Q7. This is analogous to the complement/true datum output described for the Automatic Program algorithm: the erase function changes all the bits in a sector to "1" prior to this, the device outputs the "complement" or "0". The system must provide an address within any of the sectors selected for erasure to read valid status information on Q7. If a program address falls within a protected sector, Q6 toggles for approximately 2us after the program command sequence is written, then returns to reading array data. After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on Q7 is active for approximately 100 us, then the device returns to reading array data. If not all selected sectors are protected, the Automatic Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. Q6 also toggles during the erase-suspend-program mode, and stops toggling once the Automatic Program algorithm is complete. Table 4 shows the outputs for Toggle Bit I on Q6. When the system detects Q7 has changed from the complement to true data, it can read valid data at Q7-Q0 on the following read cycles. This is because Q7 may change asynchronously with Q0-Q6 while Output Enable (OE#) is asserted low. Q2:Toggle Bit II The "Toggle Bit II" on Q2, when used with Q6, indicates whether a particular sector is actively erasing (that is, the Automatic Erase algorithm is in process), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE# or CE#, whichever happens first pulse in the command sequence. Q6:Toggle BIT I Toggle Bit I on Q6 indicates whether an Automatic Program or Erase algorithm is in progress or complete, or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is valid Q2 toggles when the system reads at addresses within those sectors that have been selected for erasure. (The system may use either OE# or CE# to control the read P/N:PM1189 REV. 0.02, JUL. 21, 2005 17 MX29LV033C cycles.) But Q2 cannot distinguish whether the sector is actively erasing or is erase-suspended. Q6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sectors and mode information. Refer to Table 4 to compare outputs for Q2 and Q6. dition. If this time-out condition occurs during sector erase operation, it specifies that a particular sector is bad and it may not be reused. However, other sectors are still functional and may be used for the program or erase operation. The device must be reset to use other sectors. Write the Reset command sequence to the device, and then execute program or erase command sequence. This allows the system to continue to use the other active sectors in the device. Reading Toggle Bits Q6/ Q2 Whenever the system initially begins reading toggle bit status, it must read Q7-Q0 at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the first. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can read array data on Q7-Q0 on the following read cycle. If this time-out condition occurs during the chip erase operation, it specifies that the entire chip is bad or combination of sectors are bad. If this time-out condition occurs during the byte programming operation, it specifies that the entire sector containing that byte is bad and this sector may not be reused, (other sectors are still functional and can be reused). However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of Q5 is high (see the section on Q5). If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as Q5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erase operation. If it is still toggling, the device did not complete the operation successfully, and the system must write the reset command to return to reading array data. The time-out condition may also appear if a user tries to program a non blank location without erasing. In this case the device locks out and never completes the Automatic Algorithm operation. Hence, the system never reads a valid data on Q7 bit and Q6 never stops toggling. Once the Device has exceeded timing limits, the Q5 bit will indicate a "1". Please note that this is not a device failure condition since the device was incorrectly used. The Q5 failure condition may appear if the system tries to program a to a "1" location that is previously programmed to "0". Only an erase operation can change a "0" back to a "1". Under this condition, the device halts the operation, and when the operation has exceeded the timing limits, Q5 produces a "1". The remaining scenario is that system initially determines that the toggle bit is toggling and Q5 has not gone high. The system may continue to monitor the toggle bit and Q5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively, it may choose to perform other system tasks. In this case, the system must start at the beginning of the algorithm when it returns to determine the status of the operation. Q3:Sector Erase Timer After the completion of the initial sector erase command sequence, the sector erase time-out will begin. Q3 will remain low until the time-out is complete. Data# Polling and Toggle Bit are valid after the initial sector erase command sequence. Q5:Program/Erase Timing Q5 will indicate if the program or erase time has exceeded the specified limits (internal pulse count). Under these conditions Q5 will produce a "1". This time-out condition indicates that the program or erase cycle was not successfully completed. Data# Polling and Toggle Bit are the only operating functions of the device under this con- If Data# Polling or the Toggle Bit indicates the device has been written with a valid erase command, Q3 may be used to determine if the sector erase timer window is still open. If Q3 is high ("1") the internally controlled erase cycle has begun; attempts to write subsequent commands P/N:PM1189 REV. 0.02, JUL. 21, 2005 18 MX29LV033C to the device will be ignored until the erase operation is completed as indicated by Data# Polling or Toggle Bit. If Q3 is low ("0"), the device will accept additional sector erase commands. To insure the command has been accepted, the system software should check the status of Q3 prior to and following each subsequent sector erase command. If Q3 were high on the second status check, the command may not have been accepted. If the time between additional erase commands from the system can be less than 50us, the system need not to monitor Q3. RY/BY#:READY/BUSY# OUTPUT The RY/BY# is a dedicated, open-drain output pin that indicates whether an Embedded Algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC . If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.) If the output is high (Ready), the device is ready to read array data (including during the Erase Suspend mode), or is in the standby mode.

QUERY COMMAND AND COMMON FLASH INTERFACE (CFI) MODE MX29LV033C is capable of operating in the CFI mode. This mode all the host system to determine the manufacturer of the device such as operating parameters and configuration. Two commands are required in CFI mode. Query command of CFI mode is placed first, then the Reset command exits CFI mode. These are described in Table 5. The Reset command exits from the CFI mode to the Read mode, or Erase Suspend mode, or Automatic Select mode. The command is valid only when the device is in the CFI mode. Table 5-1.
