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 EM39LV800 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. Word Program The EM39LV800 is programmed on a word-by-word basis. Before programming, the sector where the word 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 word address and word data. During the Word 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 Program operation, once initiated, will be completed within 20 µs. See Figures 2 and 3 for WE# and CE# controlled Program operation timing diagrams respectively and Figure 15 for 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.

Table 2: EM39LV800 Device Operation Write Command/Command Sequence The EM39LV800 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 simultaneous with the completion of 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 EM39LV800 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 17 for the flowchart. Any commands issued during the Chip-Erase operation are ignored. This specification is subject to change without further notice. (04.09.2004 V1.0) Page 5 of 25 EM39LV800 8M Bits (512Kx16) Flash Memory SPECIFICATION Sector/Block Erase The EM39LV800 offers both Sector-Erase and Block-Erase modes. The Sector- (or Block-) Erase operation allows the system to erase the device on a sector-by-sector (or block-by-block) basis. The sector architecture is based on uniform sector size of 2 KWord. The Block architecture is based on uniform block size of 32 KWord. 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 Block-Erase operation is initiated by executing a six-byte command sequence with Block-Erase command (50H) and block address (BA) 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 or 50H) 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 and 8 for timing waveforms. Any commands issued during the Sector or Block Erase operation are ignored. Data# Polling (DQ7) When the EM39LV800 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, Block-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 14 for a 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, Block-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 14 for a flowchart. Data Protection The EM39LV800 provides both hardware and software features to protect the data from inadvertent write. This specification is subject to change without further notice. (04.09.2004 V1.0) Page 6 of 25 EM39LV800 8M Bits (512Kx16) 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 EM39LV800 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 for the specific software command codes. During SDP command sequence, invalid commands will abort the device to Read mode within TRC. The contents of DQ15-DQ8 can be VIL or VIH, but no other value, during any SDP command sequence. Common Flash Memory Interface (CFI) The EM39LV800 contains the CFI information to describe the characteristics of the device. In order to enter the CFI Query mode, the system must write three-byte sequence, same as Software ID Entry command, with 98H (CFI Query command) to address 5555H in the last byte sequence. Once the device enters the CFI Query mode, the system can read CFI data at the addresses given in Tables 4 through 6. The system must write the CFI Exit command to return to Read mode from the CFI Query mode. This specification is subject to change without further notice.
