W29C040  
FUNCTIONAL DESCRIPTION  
Read Mode  
The read operation of the W29C040 is controlled by CE and OE , both Chip of which have to be low  
for the host to obtain data from the outputs. CE is used for device selection. When CE is high, the  
chip is de-selected and only standby power will be consumed. OE is the output control and is used to  
gate data from the output pins. The data bus is in high impedance state when either CE or OE is  
high.  
Refer to the read cycle timing waveforms for further details.  
Page Write Mode  
The W29C040 is written (erased/programmed) on a page basis. Every page contains 256 bytes of  
data. If a byte of data within a page is to be changed, data for the entire page must be loaded into the  
device. Any byte that is not loaded will be erased to "FF hex" during the write operation of the page.  
The write operation is initiated by forcing CE and WE low and OE high. The write procedure  
consists of two steps. Step 1 is the byte-load cycle, in which the host writes to the page buffer of the  
device.  
Step 2 is an internal write (erase/program) cycle, during which the data in the page buffers are  
simultaneously written into the memory array for non-volatile storage.  
During the byte-load cycle, the addresses are latched by the falling edge of either CE or WE ,  
whichever occurs last. The data are latched by the rising edge of either CE or WE , whichever  
occurs first. If the host loads a second byte into the page buffer within a byte-load cycle time (TBLC) of  
200 mS after the initial byte-load cycle, the W29C040 will stay in the page load cycle. Additional bytes  
can then be loaded consecutively. The page load cycle will be terminated and the internal write  
(erase/program) cycle will start if no additional byte is loaded into the page buffer. A8 to A18 specify  
the page address. All bytes that are loaded into the page buffer must have the same page address.  
A0 to A7 specify the byte address within the page. The bytes may be loaded in any order; sequential  
loading is not required.  
In the internal write cycle, all data in the page buffers, i.e., 256 bytes of data, are written  
simultaneously into the memory array. The typical write (erase/program) time is 5 mS. The entire  
memory array can be written in 10.4 seconds. Before the completion of the internal write cycle, the  
host is free to perform other tasks such as fetching data from other locations in the system to prepare  
to write the next page.  
Software-protected Data Write  
The device provides a JEDEC-approved optional software-protected data write. Once this scheme is  
enabled, any write operation requires a three-byte command sequence (with specific data to a  
specific address) to be performed before the data load operation. The three-byte load command  
sequence begins the page load cycle, without which the write operation will not be activated. This  
write scheme provides optimal protection against inadvertent write cycles, such as cycles triggered by  
noise during system power-up and power-down.  
The W29C040 is shipped with the software data protection enabled. To enable the software data  
protection scheme, perform the three-byte command cycle at the beginning of a page load cycle. The  
device will then enter the software data protection mode, and any subsequent write operation must be  
preceded by the three-byte command sequence cycle. Once enabled, the software data protection  
Publication Release Date: May 1999  
- 3 -  
Revision A5  
W29C040  
will remain enabled unless the disable commands are issued. A power transition will not reset the  
software  
data protection feature. To reset the device to unprotected mode, a six byte command sequence is  
required. For information about specific codes, see the Command Codes for Software Data  
Protection in the Table of Operating Modes. For information about timing waveforms, see the timing  
diagrams below.  
Hardware Data Protection  
The integrity of the data stored in the W29C040 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) VCC Power Up/Down Detection: The write operation is inhibited when VCC is less than 2.5V.  
(3) Write Inhibit Mode: Forcing OE low, CE high, or WE high will inhibit the write operation. This  
prevents inadvertent writes during power-up or power-down periods.  
(4) VCC power-on delay: When VCC has reach its sense level, the device will automatically time-out  
10 mS before any write (erase/program) operation.  
Chip Erase Modes  
The entire device can be erased by using a six-byte software command code. See the Software Chip  
Erase Timing Diagram.  
Boot Block Operation  
There are two boot blocks (16K bytes each) in this device, which can be used to store boot code. One  
of them is located in the first 16K bytes and the other is located in the last 16K bytes of the memory.  
The first 16K or last 16K of the memory can be set as a boot block by using a seven-byte command  
sequence.  
See Command Codes for Boot Block Lockout Enable for the specific code. Once this feature is set  
the data for the designated block cannot be erased or programmed (programming lockout); other  
memory locations can be changed by the regular programming method. Once the boot block  
programming lockout feature is activated, the chip erase function will be disabled. In order to detect  
whether the boot block feature is set on the two 16K blocks, users can perform a six-byte command  
sequence: enter the product identification mode (see Command Codes for Identification/Boot Block  
Lockout Detection for specific code), and then read from address "00002 hex" (for the first 16K bytes)  
or "7FFF2 hex" (for the last 16K bytes). If the output data is "FF hex," the boot block programming  
lockout feature is activated; if the output data is "FE hex," the lockout feature is inactivated and the  
block can be programmed.  
To return to normal operation, perform a three-byte command sequence to exit the identification  
mode. For the specific code, see Command Codes for Identification/Boot Block Lockout Detection.  
Data Polling (DQ7)- Write Status Detection  
The W29C040 includes a data polling feature to indicate the end of a write cycle. When the  
W29C040 is in the internal write cycle, any attempt to read DQ7 of the last byte loaded during the  
page/byte-load cycle will receive the complement of the true data. Once the write cycle is completed.  
DQ7 will show the true data. See the DATA Polling Timing Diagram.  
- 4 -  
W29C040  
Toggle Bit (DQ6)- Write Status Detection  
In addition to data polling, the W29C040 provides another method for determining the end of a write  
cycle. During the internal write cycle, any consecutive attempts to read DQ6 will produce alternating  
0's and 1's. When the write cycle is completed, this toggling between 0's and 1's will stop. The device  
is then ready for the next operation. See Toggle Bit Timing Diagram.  
Product Identification  
The product ID operation outputs the manufacturer code and device code. Programming equipment  
automatically matches the device with its proper erase and programming algorithms.  
The manufacturer and device codes can be accessed by software or hardware operation. In the  
software access mode, a six-byte command sequence can be used to access the product ID. A read  
from address "00000 hex" outputs the manufacturer code "DA hex." A read from address "00001 hex"  
outputs the device code "46 hex." The product ID operation can be terminated by a three-byte  
command sequence.  
In the hardware access mode, access to the product ID is activated by forcing CE and OE low, WE  
high, and raising A9 to 12 volts.
