W39V080FA
1. GENERAL DESCRIPTION
The W39V080FA is an 8-megabit, 3.3-volt only CMOS flash memory organized as 1M × 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 W39V080FA results in fast
program/erase operations with extremely low current consumption. This device can operate at two
modes, Programmer bus interface mode and FWH bus interface mode. As in the Programmer interface
mode, it acts like the traditional flash but with a multiplexed address inputs. But in the FWH interface
mode, this device complies with the Intel FWH 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 operate in two interface modes, one is Programmer interface mode, and the other is
FWH interface mode. The IC 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
IC pin is set to high state, the device will be in the Programmer mode; while the IC pin is set to low state
(or leaved no connection), it will be in the FWH 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 are mapped to the higher internal address A[19:11]. And the column address are mapped
to the lower internal address A[10:0]. For FWH mode, It complies with the FWH Interface Specification.
Through the FWH[3:0] and FWH4 to communicate with the system chipset .
6.2 Read (Write) Mode
In Programmer interface mode, the read (write) operation of the W39V080FA 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 for in the FWH interface mode, the read or write is determined
by the "bit 0 & bit 1 of START CYCLE ". Refer to the FWH cycle definition and 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 Accelerated Program Operation
The device provides accelerated program operations through the ACC function. This function is
primarily intended to allow a faster manufacturing throughput in the factory.
6.5 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.

W39V080FA
6.6 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.
6.7 Program Operation
The W39V080FA 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
byte-program command is entered. The internal program timer will automatically time-out (9μS
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.
6.8 Dual BIOS
The W39V080FA provides a solution for Dual-BIOS application. In FWH 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.
6.9 Hardware Data Protection
The integrity of the data stored in the W39V080FA 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.
- 6 -
W39V080FA
6.10 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.
6.10.1 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. 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 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.
6.10.2 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 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.
6.10.3 DQ6: Toggle Bit
Toggle Bit 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. 13, 2005

Revision A5
W39V080FA
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.
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 μs after the program command sequence is written,
and then returns to reading array data.
6.10.4 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.
6.11 Identification Input pin 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.
6.12 Register
There are three kinds of registers on this device, the General Purpose Input Registers, the Block Lock
Control 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.
6.12.1 General Purpose Inputs Register
This register reads the FGPI[4:0] pins on the W39V080FA.This is a pass-through register which can
read via memory address FFBC0100(hex). Since it is pass-through register, there is no default value.

Read Lock
Any attempt to read the data of read locked block will result in “00H.” The default state of any block is
unlocked upon power up. User can clear or set the write lock bit anytime as long as the lock down bit is
not set.
Write Lock
This is the default state of blocks upon power up. Before any program or erase to the specified block,
user should clear the write lock bit first. User can clear or set the write lock bit anytime as long as the
lock down bit is not set. The write lock function is in conjunction with the hardware protect pins, #WP &
TBL. When hardware protect pins are enabled, it will override the register block locking functions and
write lock the blocks no matter how the status of the register bits. Reading the register bit will not reflect
the status of the #WP or #TBL pins.
Lock Down
The default state of lock down bit for any block is unlocked. This bit can be set only once; any further
attempt to set or clear is ignored. Only the reset from #RESET or #INIT can clear the lock down bit.
Once the lock down bit is set for a block, then the write lock bit & read lock bit of that block will not be
set or cleared, and keep its current state.
6.12.3 Product Identification Registers
There is an alternative software method to read out the Product Identification in both the Programmer
interface mode and the FWH interface mode. Thus, the programming equipment can automatically
matches the device with its proper erase and programming algorithms.
In the full-chip(8Mb) FWH 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, D3(hex).
For Dual-BIOS(4Mbx2) FWH 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 93(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 the device code, D3(hex).” The product ID operation
can be terminated by a three-byte command sequence or an alternate one-byte command sequence
(see Command Definition table for detail).
