W39V080A
1. GENERAL DESCRIPTION
The W39V080A is an 8-megabit, 3.3-volt only CMOS flash memory organized as 1M x 8 bits. For flexible erase capability, the 8Mbits of data are divided into 16 uniform sectors of 64 Kbytes. The device can be programmed and erased in-system with a standard 3.3V power supply. A 12-volt VPP is required for accelerated program. The unique cell architecture of the W39V080A results in fast program/erase operations with extremely low current consumption. This device can operate at two modes, Programmer bus interface mode and LPC bus interface mode. As in the Programmer interface mode, it acts like the traditional flash but with a multiplexed address inputs. But in the LPC interface mode, this device complies with the Intel LPC specification. The device can also be programmed and erased using standard EPROM programmers.

6. FUNCTIONAL DESCRIPTION
6.1 Interface Mode Selection and Description
This device can be operated in two interface modes, one is Programmer interface mode, and the other is LPC interface mode. The MODE pin of the device provides the control between these two interface modes. These interface modes need to be configured before power up or return from #RESET. When MODE pin is set to high position, the device is in the Programmer mode; while the MODE pin is set to low position, it is in the LPC mode. In Programmer mode, this device just behaves like traditional flash parts with 8 data lines. But the row and column address inputs are multiplexed. The row address is mapped to the higher internal address A[19:11]. And the column address is mapped to the lower internal address A[10:0]. For LPC mode, It complies with the LPC Interface Specification Revision 1.1 Through the LAD[3:0] and #LFRAME to communicate with the system chipset .
6.2
Read (Write) Mode
In Programmer interface mode, the read(write) operation of the W39V080A is controlled by #OE (#WE). The #OE (#WE) is held low for the host to obtain (write) data from(to) the outputs(inputs). #OE is the output control and is used to gate data from the output pins. The data bus is in high impedance state when #OE is high. As in the LPC interface the "bit 1 of CYCLE TYPE+DIR" determines mode, the read or write. Refer to the timing waveforms for further details.
6.3
Reset Operation
The #RESET input pin can be used in some application. When #RESET pin is at high state, the device is in normal operation mode. When #RESET pin is at low state, it will halt the device and all outputs will be at high impedance state. As the high state re-asserted to the #RESET pin, the device will return to read or standby mode, it depends on the control signals.
6.4
Boot Block Operation and Hardware Protection at Initial- #TBL & #WP
There is a hardware method to protect the top boot block and other sectors. Before power on programmer, tie the #TBL pin to low state and then the top boot block will not be programmed/erased. If #WP pin is tied to low state before power on, the other sectors will not be programmed/erased. In order to detect whether the boot block feature is set on or not, users can perform software command sequence: enter the product identification mode (see Command Codes for Identification/Boot Block Lockout Detection for specific code), and then read from address FFFF2(hex). You can check the DQ2/DQ3 at the address FFFF2 to see whether the #TBL/#WP pin is in low or high state. If the DQ2 is "0", it means the #TBL pin is tied to high state. In such condition, whether boot block can be programmed/erased or not will depend on software setting. On the other hand, if the DQ2 is "1", it means the #TBL pin is tied to low state, then boot block is locked no matter how the software is set. Like the DQ2, the DQ3 inversely mirrors the #WP state. If the DQ3 is "0", it means the #WP pin is in high state, then all the sectors except the boot block can be programmed/erased. On the other hand, if the DQ3 is "1", then all the sectors except the boot block are programmed/erased inhibited. To return to normal operation, perform a three-byte command sequence (or an alternate single-byte command) to exit the identification mode. For the specific code, see Command Codes for Identification/Boot Block Lockout Detection.

6.5 Sector Erase Command
Sector erase is a six-bus cycles operation. There are two "unlock" write cycles, followed by writing the "set-up" command. Two more "unlock" write cycles then follows by the Sector erase command. The Sector address (any address location within the desired Sector) is latched on the rising edge of R/#C in programmer mode, while the command (30H) is latched on the rising edge of #WE. Sector erase does not require the user to program the device prior to erase. When erasing a Sector, the remaining unselected sectors are not affected. The system is not required to provide any controls or timings during these operations. The automatic Sector erase begins after the erase command is completed, right from the rising edge of the #WE pulse for the last Sector erase command pulse and terminates when the data on DQ7, Data Polling, is "1" at which time the device returns to the read mode. Data Polling must be performed at an address within any of the sectors being erased. Refer to the Erase Command flow Chart using typical command strings and bus operations.
6.6
Program Operation
The W39V080A is programmed on a byte-by-byte basis. Program operation can only change logical data "1" to logical data "0." The erase operation, which changed entire data in main memory and/or boot block from "0" to "1", is needed before programming. The program operation is initiated by a 4-byte command cycle (see Command Codes for Byte Programming). The device will internally enter the program operation immediately after the byteprogram command is entered. The internal program timer will automatically time-out (9S typ. - TBP) once it is completed and then return to normal read mode. Data polling and/or Toggle Bits can be used to detect end of program cycle.
6.7
Dual BIOS
The W39V080A provides a solution for Dual-BIOS application. In LPC mode, when D/#F is low, the device functions as a full-chip partition of 8M-bit which address ranges from FFFFFh to 00000h with A[19:0]. If D/#F is driven high, the device functions as a dual-block partition that each block consists of 4M-bit. For dual-block partition, there is only one 4M-bit block, either upper or lower, can be accessed. The U/#L pin selects either upper or lower 4M-bit block and its address ranges from 7FFFFh to 00000h with A[19:0]. When U/#L is low, the lower 4M-bit block will be selected; while, U/#L is high, the upper 4M-bit block will be selected.
6.8
Hardware Data Protection
The integrity of the data stored in the W39V080A is also hardware protected in the following ways: (1) Noise/Glitch Protection: A #WE pulse of less than 15 nS in duration will not initiate a write cycle. (2) VDD Power Up/Down Detection: The programming and read operation are inhibited when VDD is less than 2.0V typical. (3) Write Inhibit Mode: Forcing #OE low or #WE high will inhibit the write operation. This prevents inadvertent writes during power-up or power-down periods.

W39V080A
6.9 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 in programmer mode, to determine whether an Embedded Program or Erase operation is in progress or has been completed.
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. Once the Embedded Program algorithm has completed, 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 1 S, 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 100S, 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.
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 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 or standby mode.
DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete. Toggle Bit I 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 to control the read cycles. Once the operation has completed, DQ6 stops toggling. Publication Release Date: Dec. 28, 2005 Revision A4
-7-
W39V080A
After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for about 100 S, 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. The system can use DQ6 to determine whether a sector is actively erasing. If the device is actively erasing (i.e., the Embedded Erase algorithm is in progress), DQ6 toggles. If a program address falls within a protected sector, DQ6 toggles for about 1 S after the program command sequence is written, and then returns to reading array data.
Reading Toggle Bits DQ6
Whenever the system initially starts to read toggle bit status, it must read DQ7-DQ0 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 DQ7-DQ0 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 completed the operation, and the system must write the reset command to return to reading array data. 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.
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." Under both these conditions, the system must hardware reset to return to the read mode.
REGISTER
There are two kinds of registers on this device, the General Purpose Input Registers and Product Identification Registers. Users can access these registers through respective address in the 4Gbytes memory map. There are detail descriptions in the sections below. General Purpose Inputs Register This register reads the GPI[4:0] pins on the W39V080A.This is a pass-through register which can read via memory address FFBC0100(hex), or FFBxE100(hex). Since it is pass-through register, there is no default value.

There is a software method to read out the Product Identification in both the Programmer interface mode and the LPC interface mode. Thus, the programming equipment can automatically matches the device with its proper erase and programming algorithms. In the full-chip(8Mb) LPC interface mode, a read from FFBC, 0000(hex) can output the manufacturer code, DA(hex). A read from FFBC, 0001(hex) can output the device code D0(hex). For dual-BIOS(4Mbx2) LPC mode , a read from FFBC, 0000(hex) can output the manufacturer code, DA(hex). A read from FFBC,0001(hex) can output the device code 90(hex). In the software access mode, a JEDEC 3-byte command sequence can be used to access the product ID for programmer interface mode. A read from address 0000(hex) outputs the manufacturer code, DA(hex). A read from address 0001(hex) outputs sequence or an alternate one-byte command sequence (see Command Definition table for detail).the device code, D0(hex)." The product ID operation can be terminated by a three-byte command.
Identification Input Pins ID[3:0]
These pins are part of mechanism that allows multiple parts to be used on the same bus. The boot device should be 0000b. And all the subsequent parts should use the up-count strapping. Memory Address Map There are 8M bytes space reserved for BIOS Addressing. The 8M bytes are mapped into a single 4M system address by dividing the ROMs into two 4M byte pages. For accessing the 4M byte BIOS storage space, the ID[2:1] pins are inverted in the ROM and are compared to address lines [21:20]. ID[3] can be used as like active low chip-select pin. The 32Mbit address space is as below:
BLOCK LOCK ADDRESS RANGE

FFFF, FFFFh: FFC0, 0000h
The ROM responds to top 1M byte pages based on the ID pins strapping according to the following table:
