SPECIFICATION
Device Operation
The EM39LV040 uses Commands to initiate the memory operation functions. The
Commands are written to the device by asserting WE# Low while keeping CE# Low. The
address bus is latched on the falling edge of WE# or CE#, whichever occurs last. The data
bus is latched on the rising edge of WE# or CE#, whichever occurs first.
Read
The Read operation of the EM39LV040 is controlled by CE# and OE#. Both have to be Low
for the system to obtain data from the outputs. CE# is used for device selection. When CE#
is high, the chip is deselected and only standby power is 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 Diagram in Figure 1 for
further details.
Byte Program
The EM39LV040 is programmed on a byte-by-byte basis. Before programming, the sector
where the byte is located; must be erased completely. The Program operation is
accomplished in three steps:
The first step is a three-byte load sequence for Software Data Protection.
The second step is to load byte address and byte data. During the Byte Program
operation, the addresses are latched on the falling edge of either CE# or WE#, whichever
occurs last; and the data is latched on the rising edge of either CE# or WE#, whichever
occurs first.
The third step is the internal Program operation which is initiated after the rising edge of
the fourth WE# or CE#, whichever occurs first. The Pro gram operation, once initiated,
will be completed within 16 µs. See Figures 2 and 3 for WE# and CE# controlled
Program operation timing diagrams respectively and Figure 12 for the corresponding
flowchart.
During the Program operation, the only valid reads are Data# Polling and Toggle Bit. During
the internal Program operation, the host is free to perform additional tasks. Any command
issued during the internal Program operation is ignored.
This specification is subject to change without further notice. (07.22.2004 V1.0)

Table 2: EM39LV040 Device Operation
Write Command/Command Sequence
The EM39LV040 provides two software methods to detect the completion of a Program or
Erase cycle in order to optimize the system write cycle time. The software detection includes
two status bits: Data# Polling (DQ7) and Toggle Bit (DQ6). The End-of-Write detection mode
is enabled after the rising edge of WE#, which initiates the internal Program or Erase
operation. The actual completion of the write operation is asynchronous with the system;
therefore, either a Data# Polling or Toggle Bit read may be simultaneously completed with the
write cycle. If this occurs, the system may possibly get an erroneous result, i.e., valid data
may appear to conflict with either DQ7 or DQ6. In order to prevent such spurious rejection,
when an erroneous result occurs, the software routine should include an additional two times
loop to read the accessed location. If both reads are valid, then the device has completed the
write cycle, otherwise the rejection is valid.
Chip Erase
The EM39LV040 provides Chip-Erase feature, which allows the entire memory array to be
erased to logic “1” state. The Chip-Erase operation is initiated by executing a six-byte
command sequence with Chip-Erase command (10H) at address 5555H in the last byte
sequence. The Erase operation begins with the rising edge of the sixth WE# or CE#,
whichever occurs first. During the Erase operation, the only valid reads are Toggle Bit and
Data# Polling. See Table 3 for the command sequence, Figure 6 for timing diagram, and
Figure 15 for the corresponding flowchart. Any command issued during the Chip-Erase
operation is ignored.
This specification is subject to change without further notice. (07.22.2004 V1.0)

4M (512Kx8) Bits Flash Memory
SPECIFICATION
Sector Erase
The EM39LV040 offers Sector-Erase mode. The Sector-Erase operation allows the system
to erase the device on a sector-by-sector basis. The sector architecture is based on uniform
sector size of 4 KByte. The Sector-Erase operation is initiated by executing a six-byte
command sequence with Sector-Erase command (30H) and Sector Address (SA) in the last
bus cycle. The sector or block address is latched on the falling edge of the sixth WE# pulse,
while the command (30H) is latched on the rising edge of the sixth WE# pulse. The internal
Erase operation begins after the sixth WE# pulse. The End-of-Erase operation can be
determined by using either Data# Polling or Toggle Bit method. See Figures 7 for timing
waveforms. Any command issued during the Sector-Erase operation is ignored.
Data# Polling (DQ7)
When the EM39LV040 is in the internal Program operation, any attempt to read DQ7 will
produce the complement of the true data. Once the Program operation is completed, DQ7
will produce the true data. Note that even though DQ7 may have valid data immediately
following the completion of an internal Program operation, the remaining data outputs may still
be invalid (valid data on the entire data bus will appear in subsequent successive Read cycles
after an interval of 1 µs). During internal Erase operation, any attempt to read DQ7 will
produce a “0”. Once the internal Erase operation is completed, DQ7 will produce a “1”. The
Data# Polling is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation.
For Sector-Erase or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE#
(or CE#) pulse. See Figure 4 for Data# Polling timing diagram and Figure 13 for the
corresponding flowchart.
Toggle Bit (DQ6)
During the internal Program or Erase operation, any consecutive attempts to read DQ6 will
produce alternating 1s and 0s, i.e., toggling between 1 and 0. When the internal Program or
Erase operation is completed, the DQ6 bit will stop toggling. The device is then ready for the
next operation. The Toggle Bit is valid after the rising edge of fourth WE# (or CE#) pulse for
Program operation. For Sector-Erase or Chip-Erase, the Toggle Bit is valid after the rising
edge of sixth WE# (or CE#) pulse. See Figure 5 for Toggle Bit timing diagram and Figure 13
for the corresponding flowchart.
Data Protection
The EM39LV040 provides both hardware and software features to protect the data from
inadvertent write.
This specification is subject to change without further notice. (07.22.2004 V1.0)
Page 6 of 21

4M (512Kx8) Bits Flash Memory
SPECIFICATION
Hardware Data Protection
Noise/Glitch Protection:
VDD Power Up/Down Detection:
Write Inhibit Mode:
A WE# or CE# pulse of less than 5 ns will not initiate a
write cycle.
The Write operation is inhibited when VDD is less than
1.5V.
Forcing OE# Low, CE# High, or WE# High will inhibit the
Write operation. This prevents inadvertent write during
power-up or power-down.
Software Data Protection (SDP)
The EM39LV040 provides the JEDEC approved Software Data Protection (SDP) scheme for
Program and Erase operations. Any Program operation requires the inclusion of the
three-byte sequence. The three-byte load sequence is used to initiate the Program operation,
providing optimal protection from inadvertent Write operations, especially during the system
power-up or power-down transition. Any Erase operation requires the inclusion of six-byte
sequence. See Table 3 below for the specific software command codes. During SDP
command sequence, invalid commands will abort the device to Read mode within TRC.

AC test inputs are driven at VIHT (0.9 VDD) for a logic "1" and VILT(0.1 VDD) for a logic "0".
Measurement reference points for inputs and outpputs are VIT(0.5 VDD) and VOT(0.5 VDD). Input
rise and fall time (10% - 90% ) is <5ns
Note: VIT = Vinput Test
VOT = Voutput Test
VIHT = Vinput HIGH Test
VILT = Vinput LOW Test
