W39V040B  
1. GENERAL DESCRIPTION  
The W39V040B is a 4-megabit, 3.3-volt only CMOS flash memory organized as 512K × 8 bits. For  
flexible erase capability, the 4Mbits of data are divided into 8 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 W39V040B results in fast  
program/erase operations with extremely low current consumption. This device can operate at two  
modes, Programmer bus interface mode, Low pin count (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 operate 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 ic  
(Mode) pin is set to VDD, the device will be in the Programmer mode; while the Mode pin is set to low  
state (or leaved no connection), it will be 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 are mapped to the higher internal address A[18:11]. And the column  
address are mapped to the lower internal address A[10:0]. For LPC mode, it complies with the LPC  
Interface Specification, through the LAD[3:0] to communicate with the system chipset .  
6.2 Read (Write) Mode  
In Programmer interface mode, the read (write) operation of the W39V040B 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 LPC interface mode, the read or write is determined  
by the "START CYCLE ". Refer to the LPC 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 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 7FFF2(hex). You can check the  
DQ2/DQ3 at the address 7FFF2 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  
Publication Release Date: April 14, 2005  
- 5 -  
Revision A3  
W39V040B  
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 W39V040B 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.  
6.7 Hardware Data Protection  
The integrity of the data stored in the W39V040B is also hardware protected in the following ways:  
(1) Noise/Glitch Protection: A #WE pulse of less than 5 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.  
6.8 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 1µS, and then the device returns to the read mode.  
During the Embedded Erase algorithm, #Data Polling produces “0” on DQ7. Once the Embedded  
Publication Release Date: April 14, 2005  
- 6 -  
Revision A3  
W39V040B  
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.  
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  
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.  
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.  
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 write the reset command to return to the read mode.  
Multi-Chip Operation  
Multiple devices can be wired on the single LPC bus. There are four ID pins can be used to support up  
to 16 devices. But in order not to violate the BIOS ROM memory space defined by Intel, Winbond  
W39V040A will only used 3 ID pins to allow up to 8 devices, 4Mbytes for BIOS code and 4Mbytes for  
registers memory space.

7. REGISTER FOR LPC MODE  
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.  
7.1 General Purpose Inputs Register for LPC Mode  
This register reads the FGPI[4:0] pins on the W39V040B.This is a pass-through register which can read  
via memory address FBC0100(hex). Since it is pass-through register, there is no default value.

7.2 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. Note that a  
1M byte ROM will occupy two Ids. For example: a 1MByte ROM's ID is 0000b, the next ROM's ID is  
0010b. These pins all are pulled down with internal resistor.  
7.3 Product Identification Registers  
In the LPC interface mode, a read from FBC, 0000(hex) can output the manufacturer code, DA(hex). A  
read from FBC, 0001(hex) can output the device code 54(hex).  
There is an alternative software method (six commands bytes) 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 software access mode, a six-byte (or 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, 54(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).
