GENERAL DESCRIPTION The W19B160B is a 16Mbit, 2.7~3.6 volt CMOS flash memory organized as 2M × 8 or 1M × 16 bits. For flexible erase capability, the 16Mbits of data are divided into one 16Kbyte, two 8Kbyte, one 32Kbyte, and thirty-one 64Kbyte sectors. The word-wide (× 16) data appears on DQ15-DQ0, and byte-wide (× 8) data appears on DQ7−DQ0. The device can be programmed and erased in-system with a standard 2.7~3.6V power supply. A 12-volt VPP is not required. The unique cell architecture of the W19B160B results in fast program/erase operations with extremely low current consumption.

FUNCTIONAL DESCRIPTION 6.1 6.1.1 DEVICE BUS OPERATION Word/Byte Configuration The #BYTE pin controls the device data I/O pins operate whether in the byte or word configuration. When the #BYTE pin is ‘1’, the device is in word configuration; DQ15-DQ0 are active and controlled by #CE and #OE. When the #BYTE pin is ‘0’, the device is in byte configuration, and only data I/O pins DQ7-DQ0 are active and controlled by #CE and #OE. The data I/O pins DQ8-DQ14 are tri-stated, and the DQ15 pin is used as an input for the LSB (A-1) address function. 6.1.2 Reading Array Data To read array data from the outputs, the #CE and #OE pins must be set to VIL. #CE is the power control and used to select the device. #OE is the output control gates array data to the output pins. #WE should stay at VIH. The #BYTE pin determines the device outputs array data whether in words or bytes. The internal state machine is set for reading array data when device power-up, or after hardware reset. This ensures that no excess modification of the memory content occurs during the power transition. In this mode there is no command necessary to obtain array data. Standard microprocessor read cycles that assert valid addresses 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 changed. 6.1.3 Writing Commands/Command Sequences In writhing a command or command sequence (which includes programming data to the device and erasing sectors of memory), the system must drive #WE and #CE to VIL, and #OE to VIH. For program operations, the #BYTE pin determines the device accepts program data whether in bytes or in words. Refer to “Word/Byte Configuration” for more information. The erase operation can erase a sector, multiple sectors, even the entire device. The “sector address” is the address bits required to solely select a sector. 6.1.4 Program and Erase Operation Status During an erase or program operation, the system may check the status of the operation by reading the status bits on DQ7 – DQ0. Refer to “Write Operation Status” and “AC Characteristics” for more information. 6.1.5 Standby Mode When the system is not reading or writing to the device, the device will be in a standby mode. In this mode, current consumption is greatly reduced, and the outputs are in the high impedance state, independent from the #OE input. When the #CE and #RESET pins are both held at VDD ± 0.3V, the device enters into the CMOS standby mode (note that this is a more restricted voltage range than VIH.) When #CE and #RESET are -9- Publication Release Date:Jan.04, 2008 Revision A5 W19B160BT/B DATA SHEET held at VIH, but not within VDD ± 0.3V, the device will be in the standby mode, but the standby current will be greater. The device requires standard access time (tCE) for read access when the device is in either of these standby modes, before it is ready to read data. When the device is deselected during erasing or programming, the device initiates active current until the operation is completed. 6.1.6 Automatic Sleep Mode The automatic sleep mode minimizes device's energy consumption. When addresses remain stable for tACC +30 nS, the device will enable this mode automatically. The automatic sleep mode is independent from the #CE, #WE, and #OE control signals. Standard address access timings provide new data when addresses are changed. In sleep mode, output data is latched and always available to the system. 6.1.7 #RESET: Hardware Reset Pin The #RESET pin provides a hardware method to reset the device to reading array data. When the #RESET pin is set to low for at least a period of tRP, the device will immediately terminate every operations in progress, tri-states 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 mode. To ensure data integrity, the interrupted operation needs to be reinitiated when the device is ready to accept another command sequence. Current is reduced for the duration of the #RESET pulse. When #RESET is held at Vss ± 0.3V, the device initiates the CMOS standby current (ICC4). If #RESET is held at VIL but not within Vss ± 0.3V, the standby current will be greater. The #RESET pin may be tied to the system-reset circuitry. Thus the system reset would also reset the device, enabling the system to read the boot-up firmware from the device. If #RESET is asserted during the program or erase operation, the RY/#BY pin will be at “0” (busy) until the internal reset operation is complete. If #RESET is asserted when a program or erase operation is not processing (RY/#BY pin is “1”), the reset operation is completed within a time of tREADY (not during Embedded Algorithms). After the #RESET pin returns to VIH, the system can read data tRH. 6.1.8 Output Disable Mode When the #OE input is at VIH, output from the device is disabled. The output pins are set in the high impedance state. 6.1.9 Auto-select Mode The auto select mode offers manufacturer and device identification, as well as sector protection verification, through identifier codes output on DQ7-DQ0. This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm. However, the auto select codes can also be accessed in-system through the command register. When using programming equipment , the auto select mode requires VID (8.5 V to 11.5 V) on address pins A9. Address pins A6, A1, and A0 must be as shown in auto select table. In addition, when verifying sector protection, the sector address must appear on the appropriate highest order address bits. When all necessary bits have been set as required, the programming equipment may then read the corresponding identifier code on DQ7-DQ0. - 10 - W19B160BT/B DATA SHEET To access the auto select codes in-system, the host system can issue the auto select command through the command register. This method does not require VID. Also refer to the auto select Command Sequence section for more information. 6.1.10 Sector Protection and Un-protection The sector protection feature will disable both program and erase operations in any sectors. The sector un-protection feature will re-enables both program and erase operations in previously protected sectors. Sector protection / un-protection can be implemented through two methods. The primary method requires VID on the #RESET pin, and can be implemented either in-system or through programming equipment. This method uses standard microprocessor bus cycle timing. The alternate method intended only for programming equipment requires VID on address pin A9 and #OE It is possible to determine whether a sector is protected or unprotected. See the auto select Mode section for details. 6.1.11 Temporary Sector Unprotect This feature allows temporary un-protection of previously protected sectors to change data in-system. When the #RESET pin is set to VID, the Sector Unprotect mode is activated. During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses. What if VID is removed from the #RESET pin, all the previously protected sectors are protected again. 6.1.12 Hardware Data Protection The command sequence requirements of unlock cycles for programming or erasing provides data protection against negligent writes. In addition, the following hardware data protection measures prevent inadvertent erasure or programming, which might be caused by spurious system level signals during VDD power-up and power-down transitions, or from system noise. 6.1.13 Write Pulse “Glitch” Protection Noise pulses, which is less than 5nS (typical) on #OE, #CE or #WE, do not initiate a write cycle. 6.1.14 Logical Inhibit Write cycles are inhibited by holding any one of #OE = VIL, #CE = VIH or #WE = VIH. #CE and #WE must be a logical zero while #OE is a logical one to initiate a write cycle. 6.1.15 Power-Up Write Inhibit During power up, if #WE = #CE = VIL and #OE = VIH, the device does not accept commands on the rising edge of #WE. The internal state machine is automatically reset to the read mode on power-up. - 11 - Publication Release Date:Jan.04, 2008 Revision A5 W19B160BT/B DATA SHEET 6.2 COMMAND DEFINITIONS The device operation can be initiated by writing specific address and data commands or sequences into the command register. The device will be reset to reading array data when writing incorrect address and data values or writing them in the improper sequence. The addresses will be latched on the falling edge of #WE or #CE, whichever happens later; while the data will be latched on the rising edge of #WE or #CE, whichever happens first. Please refer to timing waveforms. 6.2.1 Reading Array Data After device power-up, it is automatically set to reading array data. There is no commands are required to retrieve data. After completing an Embedded Program or Embedded Erase algorithm, the device is ready to read array data. The system must initiate the reset command to return the device to read mode if DQ5 goes high during an active program or erase operation; otherwise, the device is in the auto select mode. See Reset Command section and Requirements for Reading Array Data in the Device Bus Operations section for more information. 6.2.2 Reset Command The device will be to the read when writing the reset command. For this command, the address bits are Don’t Care. The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the device to which the system was writing to the read mode. 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 which the system was writing to the read mode. The reset command may be written between the sequence cycles in an auto select command sequence. When in the auto select mode, the reset command must be written to return to the read mode. If DQ5 goes high during a program or erase operation, writing the reset command returns the device to the read mode. 6.2.3 Auto-select Command Sequence The auto select command sequence provides the host system to access the manufacturer and device codes, and determine whether a sector is protected or not. This is an alternative method, which is intended for PROM programmers and requires VID on address pin A9. The auto select command sequence may be written to an address within the device that is in the read mode. When the device is actively programming or erasing, the auto select command may not be written. The first writing two unlock cycles initiate the auto select command sequence. This is followed by a third write cycle that contains the auto select command. The device then enters into the auto select mode. The system may read at any address without initiating another auto select command sequence: • A read cycle at address XX00h returns the manufacturer code. • A read cycle at address XX01h in word mode (or XX02h in byte mode) returns the device code. • A read cycle to an address containing a sector address (SA), and the address 02h on A7-A0 in word mode (or the address 04h in byte mode) returns 01h if the sector is protected, or 00h if it is unprotected. - 12 - W19B160BT/B DATA SHEET To return to read mode and exit the auto select mode, the system must write the reset command. 6.2.4 Byte/Word Program Command Sequence The device can be programmed either by word or byte, which depending on the state of the #BYTE pin. Programming is a four-bus-cycle operation. The program command sequence is initiated by writing two unlock write cycles, followed by the program setup command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The device automatically provides internally generated program pulses and verifies the programmed cell margin. Once the Embedded Program algorithm is complete, the device then returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by using DQ7, DQ6, or RY/#BY. Please refer to the Write Operation Status section for bits' information. Any commands written to the device during the Embedded Program Algorithm are ignored. Please note that a hardware reset will immediately stop the program operation. The program command sequence should be reinitiated when the device has returned to the read mode, in order to ensure data integrity. Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from “0” back to “1.” If trying to do so may cause that device to set DQ5 = 1, or cause the DQ7 and DQ6 status bits to indicate that the operation is successful. However, a succeeding read will show that the data is still “0.” Only erase operations can change “0” to “1.” 6.2.5 Chip Erase Command Sequence Chip erase is a six-bus cycle operation. Writing two unlock cycles initiates the chip erase command sequence, which is followed by a set-up command. After chip erase command, two additional unlock write cycles are then followed, which in turn invokes the Embedded Erase algorithm. The system preprogram is not required prior to erase. Before electrical erase, the Embedded Erase algorithm automatically preprograms and verifies the entire memory for an all zero data pattern. Any controls or timings during these operations is not required in system. As the Embedded Erase algorithm is complete, the device returns to the read mode and addresses are no longer latched. The system can determine the status of the erase operation by using DQ7, DQ6, or RY/#BY. Please refer to the Write Operation Status section for information on these status bits. Any commands written during the chip erase operation will be ignored. However, a hardware reset shall terminate the erase operation immediately. If this happens, to ensure data integrity, the chip erase command sequence should be reinitiated when the device has returned to reading array data. 6.2.6 Sector Erase Command Sequence Sector erase is a six-bus cycle operation. Writing two unlock cycles initiates the sector erase command sequence, which is followed by a set-up command. Two additional unlock cycles are written, and are then followed by the address of the sector to be erased, and the sector erase command. The device does not require the system to preprogram before erase. Before electrical erase, the Embedded Erase algorithm automatically programs and verifies the entire memory for an all zero data pattern. Any controls or timings during these operations is not required in system. - 13 - Publication Release Date:Jan.04, 2008 Revision A5 W19B160BT/B DATA SHEET As the Embedded Erase algorithm is complete, the device returns to reading array data and addresses are no longer latched. Please refer to the Write Operation Status section for information on these status bits. However, a hardware reset shall terminate the erase operation immediately. If this occurs, to ensure data integrity, the sector erase command sequence should be reinitiated once the device has returned to reading array data. 6.2.7 Erase Suspend /Erase Resume Commands The Erase Suspend Command allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. This command is valid only during the sector erase operation, including the 50us time out period during the sector erase command sequence. The Erase Suspend Command is ignored if written during the chip erase operation or embedded program algorithm. Writing the Erase Suspend Command during the Sector Erase time-out immediately terminals the time-out period and suspends the erase operation. Addresses are as don’t cares when writer the Erase Suspend Command. When the Erase Suspend Command is written during a sector erase operation, the device requires a maximum of 20us to suspend the 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 the erase operation has been suspended, the system can read array data from or program data to any sector not selected for erasure. (The device “erase suspends” all sectors selected for erasure.) Normal read and writes timings and command definitions apply. Reading at any address within erasesuspended sectors produces status data on DQ7-DQ0. The system can use DQ7, or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. See Write Operation Status for information on these status bits. After an erase-suspended program operation is complete, the system can once again read array data within non-suspended sectors. 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 may also write the auto-select command sequence when the device is in the erase suspend mode. The device allows reading auto-select codes even at addresses within erasing sectors, since the codes are not stored in the memory array. When the device exits the auto-select mode, the device reverts to the erase suspend mode, and is ready for another valid operation. See Auto-select Command Sequence for more information. The system must write the erase resume command (address bits are don’t care) to exit the erase suspend mode and continue the sector erase operation. Further writes of the resume command are ignored. Another Erase Suspend Command can be written after the device has resumed erasing. 6.2.8 Unlock Bypass Command Sequence The unlock bypass feature allows the system to program bytes or words to the device faster than using the standard program command sequence. The unlock bypass command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. The device enters the unlock bypass command mode. A two-cycle unlock bypass program command sequence is all that is required to program in this mode. The first cycle in this sequence contains the unlock bypass program command, A0h; the second cycle contains the program address and data. Additional data is programmed in the same manner. This mode dispenses - 14 - W19B160BT/B DATA SHEET with the initial two unlock cycles required in the standard program command sequence, resulting in faster total programming time. Command Definitions shows the requirements for the command sequence. During the unlock bypass mode, only the Unlock Bypass Program and Unlock By-pass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command sequence. The first cycle must contain the data 90h; the second cycle the data 00h. Addresses are don’t care for both cycles. The device then returns to reading array data. Program/Erase operation refer Program Algorithm and Erase Algorithm illustration. 6.3 WRITE OPERATION STATUS The device provides several bits to determine the status of a program or erase operation: DQ5, DQ6, and DQ7. Each of DQ7 and DQ6 provides a method for determining whether a program or erase operation is complete or in progress. The device also offers a hardware-based output signal, RY/#BY, to determine whether an Embedded Program or Erase operation is in progress or has been completed. 6.3.1 DQ7: #Data Polling The #Data Polling bit, DQ7, indicates whether an Embedded Program or Erase algorithm is in progress or completed. Data Polling is valid after the rising edge of the final #WE pulse in the command sequence. During the Embedded Program algorithm, the device outputs on DQ7 and the complement of the data programmed to DQ7. When the Embedded Program algorithm is complete, the device outputs the data programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a protected sector, #Data Polling on DQ7 is active for about 1µS, and then the device returns to the read mode. During the Embedded Erase algorithm, #Data Polling produces “0” on DQ7.Once the Embedded Erase algorithm has completed, #Data Polling produces “1” on DQ7. An address within any of the sectors selected for erasure must be provided to read valid status information on DQ7. After an erase command sequence is written, if all sectors selected for erasing are protected, #Data Polling on DQ7 is active for about 100µS, and then the device returns to the 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. However, if the system reads DQ7 at an address within a protected sector, the status may not be valid. Just before the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ0-DQ6 while Output Enable (#OE) is set to low. That is, the device may change from providing status information to valid data on DQ7. Depending on when it samples the DQ7 output, the system may read the status or valid data. Even if the device has completed the program or erase operation and DQ7 has valid data, the data outputs on DQ0-DQ6 may be still invalid. Valid data on DQ7-DQ0 will appear on successive read cycles. 6.3.2 RY/#BY: Ready/#Busy The RY/#BY is a dedicated, open-drain output pin which 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 - 15 - Publication Release Date:Jan.04, 2008 Revision A5 W19B160BT/B DATA SHEET 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 VDD. When the output is low (Busy), the device is actively erasing or programming. When the output is high (Ready), the device is in the read mode. 6.3.3 DQ6: Toggle Bit Toggle Bit on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete. Toggle Bit may be read at any address, and is valid after the rising edge of the final #WE pulse in the command sequence (before the program or erase operation), and during the sector erase time-out. During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. The system may use either #OE or #CE to control the read cycles. Once the operation has completed, DQ6 stops toggling. After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for about 100µS, and then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors which are protected. If a program address falls within a protected sector, DQ6 toggles for about 1 μs after the program command sequence is written, and then returns to reading array data. 6.3.4 DQ2: Toggle Bit II When used with DQ6, the “Toggle Bit II” on DQ2 indicates whether a particular sector is actively erasing (i.e., the Embedded Erase algorithm is in progress), or the sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final #WE pulse in the command sequence. DQ2 toggles as 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 cycles.) But DQ2 cannot distinguish that whether the sector is actively erasing or is erase-suspended. By comparison, DQ6 indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Therefore, both status bits are required for sector and mode information. 6.3.5 Reading Toggle Bits DQ6/DQ2 Whenever the system initially starts to read toggle bit status, it must read DQ0−DQ7 at least twice in a row to determine whether a toggle bit is toggling or not. Typically, the system would note and store the value of the toggle bit after the first read. While after the second read, the system would compare the new value of the toggle bit with the first one. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can read array data on DQ0−DQ7 on the following read cycle. However, if after the initial two read cycles, the system finds that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high or not(see the section on DQ5). If DQ5 is high, the system should then determine again whether the toggle bit is toggling or not, 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, and the system must write the reset command to return to reading array data. - 16 - W19B160BT/B DATA SHEET Then 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, and determines the status as described in the previous paragraph. Alternatively, the system may choose to perform other system tasks. In this case, the system must start at the beginning of the algorithm while it returns to determine the status of the operation. 6.3.6 DQ3: Sector Erase Timer After writing a sector erase command sequence, the system may read DQ3 to determine whether erasure has begun or not. (The sector erase timer does not apply to the chip erase command.) The entire time-out applies after each additional sector erase command if additional sectors are selected for erasure. Once the timeout period has completed, DQ3 switches from “0” to “1.” If the time between additional sector erase commands from the system can be assumed to be less than 50 μS, the system need not monitor, DQ3 does not need to be monitored. Please also refer to Sector Erase Command Sequence section. After the sector erase command is written, the system should read the status of DQ7 (#Data Polling) or DQ6 (Toggle Bit I) to ensure that the device has accepted the command sequence, and then read DQ3. If DQ3 is“1,” the Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored until the erase operation is complete. If DQ3 is “0,” the device will accept additional sector erase commands. The system software should check the status of DQ3 before and following each subsequent sector erase command to ensure the command has been accepted. If DQ3 is high on the second status check, the last command might not have been accepted. 6.3.7 DQ5 : Exceeded Timing Limits DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. DQ5 produces “1” under these conditions which indicates that the program or erase cycle was not successfully completed. The device may output “1” on DQ5 if the system tries to program “1” to a location that was previously programmed to “0.” Only the erase operation can change “0” back to “1.” Under this condition, the device stops the operation, and while the timing limit has been exceeded, DQ5 produces “1.” 7. SPECIAL CHARACTERISTIC The W19B160B provides a good performance in the wireless products. It is concerned with access speed. If the access speed is quick to meet the demand of specification (70nS), the system’s application is widely and performance is better than other low speed products. - 17 - Publication Release Date:Jan.04, 2008 Revision A5 W19B160BT/B DATA SHEET 8.
