FUJITSU SEMICONDUCTOR DATA SHEET AE0.3E FLASH MEMORY CMOS 32 M (4M x 8/2M x 16) BIT MirrorFlashTM MBM29PL32TM/BM 90/10 n DESCRIPTION The MBM29PL32TM/BM is a 32M-bit, 3.0 V-only Flash memory organized as 4M bytes by 8 bits or 2M words by 16 bits. The MBM29PL32TM/BM is offered in 48-pin TSOP(I) and 48-ball FBGA. The device is designed to be programmed in-system with the standard 3.0 V VCC supply. 12.0 V VPP and 5.0 V VCC are not required for write or erase operations. The devices can also be reprogrammed in standard EPROM programmers. The standard MBM29PL32TM/BM offers access times of 90 ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention the devices have separate chip enable (CE), write enable (WE), and output enable (OE) controls. n PRODUCT LINE UP MBM29PL32TM/BM Part No. 90 10 3.0V to 3.6V 3.0V to 3.6V Max.

The information is intended to help you evaluate this product. Fujitsu reserves the 1 right to change this proposed product without notice. MBM29PL32TM/BM 90/10 The MBM29PL32TM/BM supports command set compatible with JEDEC single-power-supply EEPROMS standard. Commands are written into the command register. The register contents serve as input to an internal state-machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the devices is similar to reading from 5.0 V and 12.0 V Flash or EPROM devices. The MBM29PL32TM/BM is programmed by executing the program command sequence. This will invoke the Embedded Program AlgorithmTM which is an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. Typically, each sector can be programmed and verified in about 0.1 seconds. Erase is accomplished by executing the erase command sequence. This will invoke the Embedded Erase AlgorithmTM which is an internal algorithm that automatically preprograms the array if it is not already programmed before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margin. Each sector is typically erased and verified in 1.0 second. (If already completely preprogrammed.) The device also features a sector erase architecture. The sector mode allows each sector to be erased and reprogrammed without affecting other sectors. All sectors are erased when shipped from the factory. The device features single 3.0 V power supply operation for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. A low VCC detector automatically inhibits write operations on the loss of power. The end of program or erase is detected by Data Polling of DQ7, by the Toggle Bit feature on DQ6. Once the end of a program or erase cycle has been completed, the devices internally return to the read mode. Fujitsu Flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality, reliability, and cost effectiveness. The devices electrically erase all bits within a sector simultaneously via hot-hole assisted erase. The words are programmed one word at a time using the EPROM programming mechanism of hot electron injection. 2 ( AE0.3E ) Advance Info.

( AE0.3E ) 21 MBM29PL32TM/BM 90/10 n FUNCTIONAL DESCRIPTION Standby Mode There are two ways to implement the standby mode on the device, one using both the CE and RESET pins, and the other via the RESET pin only. When using both pins, CMOS standby mode is achieved with CE and RESET input held at VCC 0.3 V. Under this condition the current consumed is less than 5 A Max. During Embedded Algorithm operation, VCC active current (ICC2) is required even when CE = "H". The device can be read with standard access time (tCE) from either of these standby modes. When using the RESET pin only, CMOS standby mode is achieved with RESET input held at VSS 0.3 V (CE = "H" or "L") . Under this condition the current consumed is less than 5 A Max. Once the RESET pin is set high, the device requires tRH as a wake-up time for output to be valid for read access. During standby mode, the output is in the high impedance state, regardless of OE input. Automatic Sleep Mode Automatic sleep mode works to restrain power consumption during read-out of device data. It can be useful in applications such as handy terminal, which requires low power consumption. To activate this mode, the device automatically switch themselves to low power mode when the device addresses remain stable after 30 ns from data valid. It is not necessary to control CE, WE, and OE in this mode. The current consumed is typically 1 A (CMOS Level). Since the data are latched during this mode, the data are continuously read out. When the addresses are changed, the mode is automatically canceled and the device read-out the data for changed addresses. Autoselect The Autoselect mode allows reading out of a binary code and identifies its manufacturer and type.It is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. To activate this mode, the programming equipment must force VID on address pin A9. Two identifier bytes may then be sequenced from the devices outputs by toggling A0. All addresses can be either High or Low except A6, A3,A2,A1 and A0. See Table 2. The manufacturer and device codes may also be read via the command register, for instances when the device is erased or programmed in a system without access to high voltage on the A9 pin. The command sequence is illustrated in Table 3.Refer to Autoselect Command section. In Word mode, a read cycle from address 00h returns the manufacturer's code (Fujitsu = 04h) . A read cycle at address 01h outputs device code. When 227Eh is output, it indicates that two additional codes, called Extended Device Codes will be required. Therefore the system may continue reading out these Extended Device Codes at addresses of 0Eh and 0Fh. Notice that the above applies to Word mode. The addresses and codes differ from those of Byte mode. Refer to Table 4. Read Mode The device has two control functions required to obtain data at the outputs. CE is the power control and used for a device selection. OE is the output control and used to gate data to the output pins. Address access time (tACC) is equal to the delay from stable addresses to valid output data. The chip enable access time (tCE) is the delay from stable addresses and stable CE to valid data at the output pins. The output enable access time is the delay from the falling edge of OE to valid data at the output pins. (Assuming the addresses have been stable for at least tACC-tOE time.) When reading out a data without changing addresses after power-up, input hardware reset or to change CE pin from "H" or "L". 22 ( AE0.3E ) Advance Info. MBM29PL32TM/BM 90/10 Page Mode Read The device is capable of fast read access for random locations within limited address location called Page. The Page size of the device is 8 bytes / 4 words, within the appropriate Page being selected by the higher address bits A20 to A2 and the address bits A1 to A0 in Word mode ( A1 to A-1 in Byte mode) determining the specific word within that page. this is an asynchronous operation with the microprocessor supplying the specific word location. The initial page access is equal to the random access (tACC) and subsequent Page read access (as long as the locations specified by the microprocessor fall within that Page) is equivalent to the page address access time(tPACC). Here again, CE selects the device and OE is the output control and should be used to gate data to the output pins if the device is selected. Fast Page mode, accesses are obtained by keeping A 20 to A2 constant and changing A1 and A0 in Word mode ( A1 to A-1 in Byte mode ) to select the specific word within that Page. Output Disable With the OE input at logic high level (VIH), output from the devices are disabled. This may cause the output pins to be in a high impedance state. Write Device erasure and programming are accomplished via the command register. The contents of the register serve as inputs to the internal state machine. The state machine outputs dictate the device function. The command register itself does not occupy any addressable memory location. The register is a latch used to store the commands, along with the address and data information needed to execute the command. The command register is written by bringing WE to VIL, while CE is at VIL and OE is at VIH. Addresses are latched on the falling edge of WE or CE, whichever starts later; while data is latched on the rising edge of WE or CE, whichever starts first. Standard microprocessor write timings are used. Refer to AC Write Characteristics and the Erase/Programming Waveforms for specific timing parameters. Sector Group Protection The device features hardware sector group protection. This feature will disable both program and erase operations in any combination of thirty two sector groups of memory.See Table 6. The user`s side can use the sector group protection using programming equipment. The device is shipped with all sector groups that are unprotected. To activate it, the programming equipment must force VID on address pin A9 and control pin OE, CE = VIL and A6 = A3 = A2 = A0 = VIL, A1 = VIH. The sector group addresses (A20, A19, A18, A17, A16, A15, A14, A13, and A12) should be set to the sector to be protected. Table 5 defines the sector address for each of the seventy-one (71) individual sectors, and Table 6 defines the sector group address for each of the twenty-four (24) individual group sectors. Programming of the protection circuitry begins on the falling edge of the WE pulse and is terminated with the rising edge of the same. Sector group addresses must be held constant during the WE pulse. See Figures 18 and 26 for sector group protection timing diagram and algorithm. 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. Scanning the sector group addresses (A20, A19, A18, A17, A16, A15, A14, A13, and A12) while (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) will produce a logical "1" code at device output DQ0 for a protected sector. Otherwise the device will produce "0" for unprotected sectors. In this mode, the lower order addresses, except for A0, A1, A2, A3, and A6 can be either High or Low. Address locations with A1 = VIL are reserved for Autoselect manufacturer and device codes. A-1 requires applying to VIL on Byte mode. It is also possible to determine if a sector group is protected in the system by writing an Autoselect command. Performing a read operation at the address location XX02h, where the higher order addresses(A20, A19, A18, A17, A16, A15, A14, A13, and A12) are the desired sector group address will produce a logical "1" at DQ0 for a protected sector group. See Table 4 for Autoselect codes. Advance Info. ( AE0.3E ) 23 MBM29PL32TM/BM 90/10 Temporary Sector Group Unprotection This feature allows temporary unprotection of previously protected sector groups of the devices in order to change data. The Sector Group Unprotection mode is activated by setting the RESET pin to high voltage (VID). During this mode, formerly protected sector groups can be programmed or erased by selecting the sector group addresses. Once the V ID is taken away from the RESET pin, all the previously protected sector groups will be protected again. Refer to Figures 19 and 27. Hardware Reset The devices may be reset by driving the RESET pin to VIL from VIH. The RESET pin has a pulse requirement and has to be kept low (VIL) for at least "tRP" in order to properly reset the internal state machine. Any operation in the process of being executed will be terminated and the internal state machine will be reset to the read mode "tREADY" after the RESET pin is driven low. Furthermore, once the RESET pin goes high, the devices require an additional "tRH" before it will allow read access. When the RESET pin is low, the devices will be in the standby mode for the duration of the pulse and all the data output pins will be tri-stated. If a hardware reset occurs during a program or erase operation, the data at that particular location will be corrupted. Write Protect (WP) The Write Protection function provides a hardware method of protecting certain outermost 8K bytes / 4K words sectors without using VID. This function is one of two provided by the WP/ACC pin. If the system asserts VIL on the WP/ACC pin, the device disables program and erase functions in the outermost 8K bytes / 4K words sectors independently of whether this sector was protected or unprotected using the method described in "Sector Group Protection" above. If the system asserts VIH on the WP/ACC pin, the device reverts of whether the outermost 8K bytes / 4K words sectors were last set to be protected to the unprotected status. Sector protection or unprotection for this sector depends on whether this was last protected or unprotected using the method described in "Sector protection/unprotection". Accelerated Program Operation The device offers accelerated program operation which enables programming in high speed. If the system asserts VACC to the WP/ACC pin, the device automatically enters the acceleration mode and the time required for program operation will reduce to about 60%. This function is primarily intended to allow high speed programing, so caution is needed as the sector group becomes temporarily unprotected. The system would use a fast program command sequence when programming during acceleration mode. Set command to fast mode and reset command from fast mode are not necessary. When the device enters the acceleration mode, the device is automatically set to fast mode. Therefore, the present sequence could be used for programming and detection of completion during acceleration mode. Removing VACC from the WP/ACC pin returns the device to normal operation. Do not remove VACC from the WP/ACC pin while programming. See Figure 21 24 ( AE0.3E ) Advance Info. MBM29PL32TM/BM 90/10 n COMMAND DEFINITIONS Device operations are selected by writing specific address and data sequences into the command register. Table 3 shows the valid register command sequences. Note that the Erase Suspend (B0h) and Erase Resume (30h) commands are valid only while the Sector Erase operation is in progress. Also the Program Suspend (B0h) and Program Resume (30h) commands are valid only while the Program operation is in progress.Moreover Reset commands are functionally equivalent, resetting the device to the read mode. Please note that commands must be asserted to DQ7 to DQ0 and DQ15 to DQ8 bits are ignored. Reset Command In order to return from Autoselect mode or Exceeded Timing Limits (DQ5 = 1) to Read mode, the Reset operation is initiated by writing the Reset command sequence into the command register. The devices remain enabled for reads until the command register contents are altered. The devices will automatically be in the reset state after power-up. In this case, a command sequence is not required in order to read data. Autoselect Command Flash memories are intended for use in applications where the local CPU alters memory contents. Therefore, manufacture and device codes must be accessible while the devices reside in the target system. PROM programmers typically access the signature codes by raising A9 to a high voltage. However applying high voltage onto the address lines is not generally desired system design practice. The device contains an Autoselect command operation to supplement traditional PROM programming methodology. The operation is initiated by writing the Autoselect command sequence into the command register. The Autoselect command sequence is initiated first by writing two unlock cycles. This is followed by a third write cycle that contains the address and the Autoselect command. Then the manufacture and device codes can be read from the address, and an actual data of memory cell can be read from the another address. Following the command write, a read cycle from address 00h returns the manufactures's code (Fujitsu = 04h). A read cycle at address 01h outputs device code. When 227Eh is output, it indicates that two additional codes, called Extended Device Codes will be required. Therefore the system may continue reading out these Extended Device Codes at address of 0Eh as well as at 0Fh. Notice that above applies to Word mode. The addresses and codes differ from those of Byte mode. Refer to Table 4. To terminate the operation, it is necessary to write the Reset command into the register. To execute the Autoselect command during the operation, Reset command must be written before the Autoselect command. Advance Info. ( AE0.3E ) 25 MBM29PL32TM/BM 90/10 Programming The devices are programmed on a word-by-word (or byte-by-byte ) basis. Programming is a four bus cycle operation. There are two "unlock" write cycles. These are followed by the program set-up command and data write cycles. Addresses are latched on the falling edge of CE or WE, whichever happens later and the data is latched on the rising edge of CE or WE, whichever happens first. The rising edge of CE or WE (whichever happens first) starts programming. Upon executing the Embedded Program Algorithm command sequence, the system is not required to provide further controls or timings. The device will automatically provide adequate internally generated program pulses and verify the programmed cell margin. The system can determine the status of the program operation by using DQ7 (Data Polling), DQ6 (Toggle Bit) or RY/BY. The Data Polling and Toggle Bit are automatically performed at the memory location being programmed. The programming operation is completed when the data on DQ7 is equivalent to data written to this bit at which the devices return to the read mode and plogram addresses are no longer latched. Therefore, the devices require that a valid address to the devices be supplied by the system at this particular instance. Hence Data Polling requires the same address which is being programmed. If hardware reset occurs during the programming operation, the data being written is not guaranteed. Programming is allowed in any address sequence and across sector boundaries. Beware that a data "0" cannot be programmed back to a "1". Attempting to do so may result in either failure condition or an apparent success according to the data polling algorithm. But a read from Reset mode will show that the data is still "0". Only erase operations can convert "0"s to "1"s. Note that attempting to program a "1" over a "0" will result in programming failure. This precaution is the same with Fujitsu standard NOR devices. Figure 22 illustrates the Embedded ProgramTM Algorithm using typical command strings and bus operations. Program Suspend/Resume The Program Suspend command allows the system to interrupt a program operation so that data can be read from any address. Writing the Program Suspend command (B0h) during Embedded Program operation immediately suspends the programming. The Program Suspend command can also be issued during a programming operation while an erase is suspended. Refer to "Erase Suspend/Resume" for the detail. When the Program Suspend command is written during a programming process, the device halts the program operation within 1us and updates the status bits.After the program operation has been suspended, the system can read data from any address. The data at program-suspended address is not valid. Normal read timing and command definitions apply. After the Program Resume command (30h) is written, the device reverts to programming. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard program operation. See "Write Operation Status" for more information. The system also writes the Autoselect command sequence in the Program Suspend mode. The device allows reading Autoselect codes at the addresses within programming sectors, since the codes are not stored in the memory. When the device exits the Autoselect mode, the device reverts to the Program Suspend mode, and is ready for another valid operation. See "Autoselect Command Sequence" for more information. The system must write the Program Resume command to exit from the Program Suspend mode and continue the programming operation. Further writes of the Resume command are ignored. Another Program Suspend command can be written after the device resumes programming. 26 ( AE0.3E ) Advance Info. MBM29PL32TM/BM 90/10 Write Buffer Programming Operations Write Buffer Programming allows the system write to series of 16 words in one programming operation. This results in faster effective word programming time than the standard programming algorithms. The Write Buffer Programming command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle selecting the Sector Address in which programming will occur. In forth cycle contains both Sector Address and unique code for data bus width will be loaded into the page buffer at the Sector Address in which programming will occur. The system then writes the starting address/data combination. This "starting address" must be the same Sector Address used in third and fourth cycles and its lower addresses of A3 to A0 should be 0h. All subsequent address must be incremented by 1. Addresses are latched on the falling edge of CE or WE, whichever happens later and the data is latched on the rising edge of CE or WE, whichever happens first. The rising edge of CE or WE (whichever happens first) starts programming. Upon executing the Write Buffer Programming Operations command sequence, the system is not required to provide further controls or timings. The device will automatically provide adequate internally generated program pulses and verify the programmed cell margin. DQ7(Data Polling), DQ6(Toggle Bit), DQ5(Exceeded Timing Limits), DQ1(Write-to-Buffer Abort) should be monitored to determine the device status during Write Buffer Programming. In addition to these functions, it is also possible to indicate to the host system that Write Buffer Programming Operations are either in progress or have been completed by RY/BY. See Table9 "Hardware Sequence Flags". The Data polling techniques described in Figure 24 should be used while monitoring the last address location loaded into the write buffer. In addition, it is not neccessary to specify an address in Toggle Bit techniques described in Figure 25. The automatic programing operation is completed when the data on DQ7 is equivalent to the data written to this bit at which time the device returns to the read mode and addresses are no longer latched ( See Table9 " Hardware Sequence Flags"). The write-buffer programming operation can be suspended using the standard program suspend/resume commands. Once the write buffer programming is set, the system must then write the "Program Buffer to Flash" command at the Sector Address. Any other address/data combination will abort the Write Buffer Programming operation and the device will continue busy state. The Write Buffer Programming Sequence can be ABORTED by doing the following : * Different Sector Address is asserted. * Write data other than the "Program Buffer to Flash" command after the specified number of "data load" cycles. A "Write-to-Buffer-Abort Reset" command sequence must be written to the device to return to read mode. (See Table 3 for details on this command sequence.) Advance Info. ( AE0.3E ) 27 MBM29PL32TM/BM 90/10 Chip Erase Chip erase is a six bus cycle operation. It begins two "unlock" write cycles followed by writing the "set-up" command, and two "unlock" write cycles followed by the chip erase command which invokes the Embedded Erase algorithm. The device does not require the user to program the device prior to erase. Upon executing the Embedded Erase Algorithm the devices automatically programs and verifies the entire memory for an all zero data pattern prior to electrical erase (Preprogram function). The system is not required to provide any controls or timings during these operations. The system can determine the erase operation status by using DQ7 (Data Polling), DQ6 (Toggle Bit I) and DQ2 (Toggle Bit II) or RY/BY output signal. The chip erase begins on the rising edge of the last CE or WE, whichever happens first from last command sequence and completes when the data on DQ7 is "1" (See Write Operation Status section.) at which time the device returns to read mode. Sector Erase Sector erase is a six bus cycle operation. There are two "unlock" write cycles. These are followed by writing the "set-up" command. Two more "unlock" write cycles are then followed by the Sector Erase command. Multiple sectors may be erased concurrently by writing the same six bus cycle operations. This sequence is followed by writes of the Sector Erase command to addresses in other sectors desired to be concurrently erased. The time between writes must be less than Erase Time-out time(tTOW). Otherwise that command will not be accepted and erasure will not start. It is recommended that processor interrupts be disabled during this time to guarantee this condition. The interrupts can reoccur after the last Sector Erase command is written. A time-out of "tTOW" from the rising edge of last CE or WE, whichever happens first, will initiate the execution of the Sector Erase command(s). If another falling edge of CE or WE, whichever happens first occurs within the "tTOW" time-out window the timer is reset (monitor DQ3 to determine if the sector erase timer window is still open, see section DQ3, Sector Erase Timer). Resetting the devices once execution has begun will corrupt the data in the sector. In that case, restart the erase on those sectors and allow them to complete (refer to the Write Operation Status). Loading the sector erase buffer may be done in any sequence and with any number of sectors (0 to 70). Sector erase does not require the user to program the devices prior to erase. The devices automatically program all memory locations in the sector(s) to be erased prior to electrical erase using the Embedded Erase Algorithm. When erasing a sector, the remaining unselected sectors remain unaffected. The system is not required to provide any controls or timings during these operations. The system can determine the status of the erase operation by using DQ7 (Data Polling), DQ6 (Toggle Bit) or RY/BY. The sector erase begins after the "tTOW" time-out from the rising edge of CE or WE whichever happens first for the last sector erase command pulse and completes when the data on DQ7 is "1" (see Write Operation Status section), at which the devices return to the read mode. Data polling and Toggle Bit must be performed at an address within any of the sectors being erased. 28 ( AE0.3E ) Advance Info. MBM29PL32TM/BM 90/10 Erase Suspend/Resume The Erase Suspend command allows the user to interrupt Sector Erase operation and then perform read or programming to a sector not being erased. This command is applicable ONLY during the Sector Erase operation within the time-out period for sector erase. Writting the Erase Suspend command (B0h) during the Sector Erase time-out results in immediate termination of the time-out period and suspension of the erase operation. Writing the "Erase Resume" command (30h) resumes the erase operation. When the "Erase Suspend" command is written during the Sector Erase operation, the device takes maximum of "tSPD" to suspend the erase operation. When the devices enter the erase-suspended mode, the RY/BY output pin will be at Hi-Z and the DQ7 bit will be at logic "1" and DQ6 will stop toggling. The user must use the address of the erasing sector for reading DQ6 and DQ7 to determine if the erase operation has been suspended. Further writes of the Erase Suspend command are ignored. When the erase operation is suspended, the devices default to the erase-suspend-read mode. Reading data in this mode is the same as reading from the standard read mode, except that the data must be read from sectors that have not been erase-suspended. Reading successively from the erase-suspended sector while the device is in the erase-suspend-read mode will cause DQ2 to toggle. see the section on DQ2. After entering the erase-suspend-read mode, the user can program the device by writing the appropriate command sequence for Program. This program mode is known as the erase-suspend-program mode. Again, it is the same as programming in the regular Program mode, except that the data must be programmed to sectors that are not erase-suspended. Reading successively from the erase-suspended sector while the devices are in the erase-suspend-program mode will cause DQ2 to toggle. The end of the erase-suspended Program operation is detected by the Data polling of DQ7 or by the Toggle Bit I of DQ6, which is the same as the regular Program operation. Note that DQ 7 must be read from the Program address while DQ6 can be read from any address. To resume the operation of Sector Erase, the Resume command (30h) should be written. Any further writes of the Resume command at this point will be ignored. Another Erase Suspend command can be written after the chip has resumed erasing. Fast Mode Set/Reset The device has Fast Mode function. It dispenses with the initial two unclock cycles required in the standard program command sequence by writing Fast Mode command into the command register. In this mode, the required bus cycle for programming consists of two cycles instead of four bus cycles in standard program command. Do not write erase command in this mode. The read operation is also executed after exiting this mode. To exit from this mode, write Fast Mode Reset command into the command register. (Refer to the Figure 29.) The VCC active current is required even CE = VIH during Fast Mode. Fast Programming During Fast Mode, the programming can be executed with two bus cycles operation. The Embedded Program Algorithm is executed by writing program set-up command (A0h) and data write cycles (PA/PD). see Figure 29. Extended Sector Group Protection In addition to normal sector group protection, the device has Extended Sector Group Protection as extended function. This function enables protection of the sector group by forcing VID on RESET pin and writes a command sequence. Unlike conventional procedures, it is not necessary to force VID and control timing for control pins. The only RESET pin requires VID for sector group protection in this mode. The extended sector group protection requires VID on RESET pin. With this condition, the operation is initiated by writing the setup command (60h) into the command register. Then the sector group addresses pins (A 20, A19, A18, A17, A16 and A15) and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) should be set to the sector group to be protected (set VIL for the other addresses pins is recommended), and write extended sector group protection command (60h). A sector group is typically protected in 250 s. To verify programming of the protection circuitry, the sector Advance Info. ( AE0.3E ) 29 MBM29PL32TM/BM 90/10 group addresses pins (A20, A19, A18, A17, A16 and A15) and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) should be set and write a command (40h). Following the command write, a logical "1" at device output DQ0 will produce for protected sector in the read operation. If the output data is logical "0", write the extended sector group protection command (60h) again. To terminate the operation, set RESET pin to VIH. (Refer to the Figures 20 and 28.) Query Command (CFI : Common Flash Memory Interface) The CFI (Common Flash Memory Interface) specification outlines device and host system software interrogation handshake which allows specific vendor-specified software algorithms to be used for entire families of devices. This allows device-independent, JEDEC ID-independent, and forward-and backwardcompatible software support for the specified flash device families. Refer to CFI specification in detail. The operation is initiated by writing the query command (98h) into the command register. Following the command write, a read cycle from specific address retrieves device information. Please note that output data of upper byte (DQ15 to DQ8) is "0". Refer to the CFI code table. To terminate operation, it is necessary to write the Reset command sequence into the register. (See Table 7.) HiddenROM (Hi-ROM) Mode (1) HiddenROM (Hi-ROM) Region The HiddenROM (Hi-ROM) feature provides a Flash memory region that the system may access through a new command sequence. This is primarily intended for customers who wish to use an Electronic Serial Number (ESN) in the device with the ESN protected against modification. Once the Hi-ROM region is protected, any further modification of that region is impossible. This ensures the security of the ESN once the product is shipped to the field. The Hi-ROM region is 256 bytes / 128 words in length. After the system writes the Hi-ROM Entry command sequence, it may read the Hi-ROM region by using device addresses A6 to A0 (A20 to A7 are all "0"). That is, the device sends only program command that would normally be sent to the address to the Hi-ROM region. This mode of operation continues until the system issues the Exit Hi-ROM command sequence, or until power is removed from the device. On power-up, or following a hardware reset, the device reverts to sending commands to the address. If you request Fujitsu to program the ESN in the device, please contact a Fujitsu representative for more information. (2) HiddenROM (Hi-ROM) Entry Command The device has a Hi-ROM area with One Time Protect function. This area is to enter the security code and to unable the change of the code once set. Programming is allowed in this area until it is protected. However, once it gets protected, it is impossible to unprotect. Therefore, extreme caution is required. The Hi-ROM area is 256 bytes / 128 words. This area is in SA0 . Therefore, write the Hi-ROM entry command sequence to enter the Hi-ROM area. It is called Hi-ROM mode when the Hi-ROM area appears. Sectors other than the block area SA0 can be read during Hi-ROM mode. Read/program of the Hi-ROM area is possible during Hi-ROM mode. Write the Hi-ROM reset command sequence to exit the Hi-ROM mode. (3) HiddenROM (Hi-ROM) Program Command To program the data to the Hi-ROM area, write the Hi-ROM program command sequence during Hi-ROM mode. This command is the same as the usual program command, except that it needs to write the command during Hi-ROM mode. Therefore the detection of completion method is the same as in the past, using the DQ7 data pooling, DQ6 Toggle bit or RY/BY. You should pay attention to the address to be programmed. If an address not in the Hi-ROM area is selected, the previous data will be deleted. 30 ( AE0.3E ) Advance Info. MBM29PL32TM/BM 90/10 (4) HiddenROM (Hi-ROM) Protect Command There are two methods to protect the Hi-ROM area. One is to write the sector group protect setup command (60h) , set the sector address in the Hi-ROM area and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) , and write the sector group protect command (60h) during the Hi-ROM mode. The same command sequence may be used because it is the same as the extension sector group protect in the past, except that it is in the Hi-ROM mode and does not apply high voltage to the RESET pin. Please refer to above mentioned "Extended Sector Group Protection" for details of sector group protect setting. The other method is to apply high voltage (VID) to A9 and OE, set the sector address in the Hi-ROM area and (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) , and apply the write pulse during the Hi-ROM mode. To verify the protect circuit, apply high voltage (VID) to A9, specify (A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0) and the sector address in the Hi-ROM area, and read. When "1" appears on DQ0, the protect setting is completed. "0" will appear on DQ0 if it is not protected. Apply write pulse again. The same command sequence could be used for the above method because other than the Hi-ROM mode, it is the same as the sector group protect previously mentioned. Take note that other sector groups will be affected if an address other than those for the Hi-ROM area is selected for the sector group address, so please be careful. Pay close attention that once it is protected, protection CANNOT BE CANCELLED. Advance Info. ( AE0.3E ) 31 MBM29PL32TM/BM 90/10 Write Operation Status Detailed in Table 9 are all the status flags which can determine the status of the device for current mode operation. During sector erase, the part provides the status flags automatically to the I/O ports. The information on DQ2 is address sensitive. If an address from an erasing sector is consecutively read, then the DQ2 bit will toggle. However DQ2 will not toggle if an address from a non-erasing sector is consecutively read. This allows the user to determine which sectors are erasing. Once erase suspend is entered address sensitivity still applies. If the address of a non-erasing sector (one available for read) is provided, then stored data can be read from the device. If the address of an erasing sector (one unavailable for read) is applied, the device will output its status bits.

Note that DQ7 during Write-Buffer-Programming indicates the data-bar for DQ7 data for the LAST LOADED WRITE-BUFFER ADDRESS location. 32 ( AE0.3E ) Advance Info. MBM29PL32TM/BM 90/10 DQ7 Data Polling The devices feature Data Polling as a method to indicate to the host that the Embedded Algorithms are in progress or completed. During the Embedded Program Algorithm, an attempt to read devices will produce reverse data last written to DQ7. Upon completion of the Embedded Program Algorithm, an attempt to read the device will produce true data last written to DQ7. During the Embedded Erase Algorithm, an attempt to read the device will produce a "0" at the DQ7 output. Upon completion of the Embedded Erase Algorithm, an attempt to read device will produce a "1" at the DQ7 output. The flowchart for Data Polling (DQ7) is shown in Figure 24. For programming, the Data Polling is valid after the rising edge of fourth write pulse in the four write pulse sequence. For chip erase and sector erase, the Data Polling is valid after the rising edge of the sixth write pulse in the six write pulse sequence. Data Polling must be performed at sector addresses of sectors being erased, not protected sectors. Otherwise, the status may become invalid. If a program address falls within a protected sector, Data polling on DQ7 is active for approximately 1 s, then the device returns to read mode. After an erase command sequence is written, if all sectors selected for erasing are protected, Data Polling on DQ7 is active for approximately 100 s, then the device returns to read mode. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. Once the Embedded Algorithm operation is close to being completed, the device data pins (DQ 7) may change asynchronously while the output enable (OE) is asserted low. This means that the device is driving status information on DQ7 at one instant of time, and then that byte's valid data the next. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device completes the Embedded Algorithm operation and DQ7 has a valid data, the data outputs on DQ6 to DQ0 may still be invalid. The valid data on DQ7 to DQ0 will be read on the successive read attempts. The Data Polling feature is active only during the Embedded Programming Algorithm, Embedded Erase Algorithm, Erace Suspendmode or sector erase time-out. See Figure 12 for the Data Polling timing specifications and diagram. DQ6 Toggle Bit I The device also feature the "Toggle Bit I" as a method to indicate to the host system that the Embedded Algorithms are in progress or completed. During an Embedded Program or Erase Algorithm cycle, successive attempts to read (CE or OE toggling) data from the devices will result in DQ 6 toggling between one and zero. Once the Embedded Program or Erase Algorithm cycle is completed, DQ6 will stop toggling and valid data will be read on the next successive attempts. During programming, the Toggle Bit I is valid after the rising edge of the fourth write pulse in the four write pulse sequences. For chip erase and sector erase, the Toggle Bit I is valid after the rising edge of the sixth write pulse in the six write pulse sequences. The Toggle Bit I is active during the sector time out. In programm operation, if the sector being written to is protected, the Toggle bit will toggle for about 1 s and then stop toggling with the data unchanged. In erase, the device will erase all the selected sectors except for the protected ones. If all selected sectors are protected, the chip will toggle the Toggle bit for about 100 s and then drop back into read mode, having data kept remained. Either CE or OE toggling will cause the DQ6 to toggle. See Figure 13 for the Toggle Bit I timing specifications and diagram. Advance Info. ( AE0.3E ) 33 MBM29PL32TM/BM 90/10 DQ5 Exceeded Timing Limits DQ5 will indicate if the program or erase time has exceeded the specified limits (internal pulse count). Under these conditions DQ5 will produce a "1". This is a failure condition indicating that the program or erase cycle was not successfully completed. Data Polling is the only operating function of the device under this condition. The CE circuit will partially power down the device under these conditions (to approximately 2 mA). The OE and WE pins will control the output disable functions as described in Table 2. The DQ5 failure condition may also appear if a user tries to program a non blank location without pre-erase. In this case the device locks out and never completes the Embedded Algorithm operation. Hence, the system never reads a valid data on DQ7 bit and DQ6 never stop toggling. Once the device has exceeded timing limits, the DQ5 bit will indicate a "1". Note that this is not a device failure condition since the device was incorrectly used. If this occurs, reset the device with command sequence. DQ3 Sector Erase Timer After the completion of the initial sector erase command sequence the sector erase time-out will begin. DQ3 will remain low until the time-out is complete. Data Polling and Toggle Bit are valid after the initial sector erase command sequence. If Data Polling or the Toggle Bit I indicates a valid erase command has been written, DQ3 may be used to determine whether the sector erase timer window is still open. If DQ3 is "1" the internally controlled erase cycle has begun. If DQ3 is "0", the device will accept additional sector erase commands. To insure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent Sector Erase command. If DQ3 were high on the second status check, the command may not have been accepted. See Table 9, Hardware Sequence Flags. DQ2 Toggle Bit II This Toggle bit II, along with DQ6, can be used to determine whether the devices are in the Embedded Erase Algorithm or in Erase Suspend. Successive reads from the erasing sector will cause DQ2 to toggle during the Embedded Erase Algorithm. If the devices are in the erase-suspended-read mode, successive reads from the erase-suspended sector will cause DQ2 to toggle. When the device is in the erase-suspended-program mode, successive reads from the non-erase suspended sector will indicate a logic "1" at the DQ 2 bit. DQ6 is different from DQ2 in that DQ6 toggles only when the standard program or Erase, or Erase Suspend Program operation is in progress. The behavior of these two status bits, along with that of DQ 7, is summarized as follows: For example, DQ2 and DQ6 can be used together to determine if the erase-suspend-read mode is in progress. (DQ2 toggles while DQ6 does not.) See also Table 9 and Figure 14. Furthermore, DQ2 can also be used to determine which sector is being erased. At the erase mode, DQ2 toggles if this bit is read from an erasing sector. Reading Toggle Bits DQ6 / DQ2 Whenever the system initially begins reading Toggle bit status, it must read DQ7 to DQ0 at least twice in a row to determine whether a Toggle bit is toggling. Typically a 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 DQ7 to DQ0 on the following read cycle. 34 ( AE0.3E ) Advance Info. MBM29PL32TM/BM 90/10 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 DQ5 is high (see the section on DQ5) . 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 DQ5 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 remaining scenario is that the system initially determines that the Toggle bit is toggling and DQ5 has not gone high. The system may continue to monitor the Toggle bit and DQ5 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. (Refer to Figure 25.)

DQ1 Write-to-Buffer Abort DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these conditions DQ1 produces a "1" The system must issue the Write-to-Buffer-Abort-Reset command sequence to return the device to reading array data. See "Write Buffer Programming Operations" section for more details. RY/BY Ready/Busy The device provides a RY/BY open-drain output pin to indicate to the host system that the Embedded Algorithms are either in progress or has been completed. If the output is low, the device is busy with either a program or erase operation. If the output is high, the device is ready to accept any read/write or erase operation. If the device is placed in an Erase Suspend mode, the RY/BY output will be high, by means of connecting with a pull-up resister to VCC. During programming, the RY/BY pin is driven low after the rising edge of the fourth WE pulse. During an erase operation, the RY/BY pin is driven low after the rising edge of the sixth WE pulse. The RY/BY pin will indicate a busy condition during the RESET pulse. See Figure 15 and 17 for a detailed timing diagram. The RY/BY pin is pulled high in standby mode. Since this is an open-drain output, RY/BY pins can be tied together in parallel with a pull-up resistor to VCC. Word/Byte Configuration BYTE pin selects the byte (8-bit) mode or word (16-bit) mode for the device. When this pin is driven high, the device operates in the word (16-bit) mode. Data is read and programmed at DQ15 to DQ0. When this pin is driven low, the device operates in byte (8-bit) mode. In this mode, DQ15/A-1 pin becomes the lowest address bit, and DQ14 to DQ8 bits are tri-stated. However, the command bus cycle is always an 8-bit operation and hence commands are written at DQ7 to DQ0 and DQ15 to DQ8 bits are ignored. Advance Info. ( AE0.3E ) 35 MBM29PL32TM/BM 90/10 Data Protection The device is designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transitions. During power up the device automatically reset the internal state machine in Read mode. Also, with its control register architecture, alteration of memory contents only occurs after successful completion of specific multi-bus cycle command sequences. The device also incorporates several features to prevent inadvertent write cycles resulting form VCC powerup and power-down transitions or system noise. (1) Low VCC Write Inhibit To avoid initiation of a write cycle during VCC power-up and power-down, a write cycle is locked out for VCC less than VLKO. If VCC < VLKO, the command register is disabled and all internal program/erase circuits are disabled. Under this condition, the device will reset to the read mode. Subsequent writes will be ignored until the VCC level is greater than VLKO. It is the user's responsibility to ensure that the control pins are logically correct to prevent unintentional writes when VCC is above VLKO. If Embedded Erase Algorithm is interrupted, the intervened erasing sector(s) is(are) not valid. (2) Write Pulse "Glitch" Protection Noise pulses of less than 3 ns (typical) on OE, CE, or WE will not initiate a write cycle. (3) Logical Inhibit Writing is inhibited by holding any one of OE = VIL, CE = VIH, or WE = VIH. To initiate a write, CE and WE must be a logical zero while OE is a logical one. (4) Power-up Write Inhibit Power-up of the devices with WE = CE = VIL and OE = VIH will not accept commands on the rising edge of WE. The internal state machine is automatically reset to read mode on power-up. (5) Sector Protection Device user is able to protect each sector group individually to store and protect data. Protection circuit voids both write and erase commands that are addressed to protected sectors. Any commands to write or erase addressed to protected sector are ignored . 36 ( AE0.3E ) Advance Info.
