If allowed to time out, a page or byte write will begin; however a transition from HIGH to LOW within t BLC max. stops the timer.DEVICE OPERATIONReadData stored in the CAT28LV64 is transferred to the data bus when WE is held high, and both OE and CE are held low.The data bus is set to a high impedance state when either CE or OE goes high. This 2−line control architecture can be used to eliminate bus contention in a system environment.Byte WriteA write cycle is executed when both CE and WE are low,and OE is high. Write cycles can be initiated using either WE or CE, with the address input being latched on the falling edge of WE or CE, whichever occurs last. Data, conversely,is latched on the rising edge of WE or CE, whichever occurs first. Once initiated, a byte write cycle automatically erases the addressed byte and the new data is written within 5 ms.ADDRESSDATA OUTCEOEWEFigure 5. Byte Write Cycle [WE Controlled]CEOEWEADDRESSDATA INPage WriteThe page write mode of the CAT28LV64 (essentially an extended BYTE WRITE mode) allows from 1 to 32 bytes of data to be programmed within a single EEPROM write cycle. This effectively reduces the byte −write time by a factor of 32.Following an initial WRITE operation (WE pulsed low,for t WP , and then high) the page write mode can begin by issuing sequential WE pulses, which load the address and data bytes into a 32 byte temporary buffer. The page address where data is to be written, specified by bits A 5 to A 12, is latched on the last falling edge of WE. Each byte within the page is defined by address bits A 0 to A 4 (which can be loadedin any order) during the first and subsequent write cycles.Each successive byte load cycle must begin within t BLC MAX of the rising edge of the preceding WE pulse. There is no page write window limitation as long as WE is pulsed low within t BLC MAX .Upon completion of the page write sequence, WE must stay high a minimum of t BLC MAX for the internal automatic program cycle to commence. This programming cycle consists of an erase cycle, which erases any data that existed in each addressed cell, and a write cycle, which writes new data back into the cell. A page write will only write data to the locations that were addressed and will not rewrite the entire page.Figure 6. Byte Write Cycle [CE Controlled]CEOEWEADDRESSDATA OUTDATA INADDRESSI/OFigure 7. Page Mode Write CycleOECEWEDATA PollingDATA polling is provided to indicate the completion of write cycle. Once a byte write or page write cycle is initiated,attempting to read the last byte written will output the complement of that data on I/O 7 (I/O 0–I/O 6 are indeterminate) until the programming cycle is complete.Upon completion of the self −timed write cycle, all I/O’s will output true data during a read cycle.Toggle BitIn addition to the DATA Polling feature, the device offers an additional method for determining the completion of a write cycle. While a write cycle is in progress, reading data from the device will result in I/O 6 toggling between one and zero. However, once the write is complete, I/O 6 stops toggling and valid data can be read from the device.Figure 8. DATA PollingADDRESSI/O7WEOECEFigure 9. Toggle Bit13.Beginning and ending state of I/O 6 is indeterminate.Hardware Data ProtectionThe following is a list of hardware data protection features that are incorporated into the CAT28LV64.1.V CC sense provides for write protection when V CC falls below2.0 V min.2.A power on delay mechanism, t INIT (see ACcharacteristics), provides a 5 to 10 ms delay before a write sequence, after V CC has reached 2.40 V min.3.Write inhibit is activated by holding any one of OE low, CE high or WE high.4.Noise pulses of less than 20 ns on the WE or CE inputs will not result in a write cycle.Software Data ProtectionThe CAT28LV64 features a software controlled data protection scheme which, once enabled, requires a data algorithm to be issued to the device before a write can be performed. The device is shipped from ON Semiconductor with the software protection NOT ENABLED (the CAT28LV64 is in the standard operating mode).Figure 10. Write Sequence for Activating SoftwareData Protection Figure 11. Write Sequence for DeactivatingSoftware Data ProtectionSOFTWARE DATAPROTECTION ACTIVATED (Note 14)14.Write protection is activated at this point whether or not any more writes are completed. Writing to addresses must occur within t BLC Max.,after SDP activation.To activate the software data protection, the device must be sent three write commands to specific addresses with specific data (Figure 10). This sequence of commands (along with subsequent writes) must adhere to the page write timing specifications (Figure 12). Once this is done, all subsequent byte or page writes to the device must be preceded by this same set of write commands. The data protection mechanism is activated until a deactivate sequence is issued regardless of power on/off transitions.This gives the user added inadvertent write protection on power −up in addition to the hardware protection provided.To allow the user the ability to program the device with an EEPROM programmer (or for testing purposes) there is a software command sequence for deactivating the data protection. The six step algorithm (Figure 11) will reset the internal protection circuitry, and the device will return to standard operating mode (Figure 13 provides reset timing).After the sixth byte of this reset sequence has been issued,standard byte or page writing can commence.Figure 12.

Once initiated, a byte write cycle automatically erases the addressed byte and the new data is written within 5 ms.DEVICE OPERATIONReadData stored in the CAT28LV65 is transferred to the data bus when WE is held high, and both OE and CE are held low. The data bus is set to a high impedance state when either CE or OE goes high. This 2-line control architec-ture can be used to eliminate bus contention in a system environment.CAT28LV657Doc. No. 1024, Rev. DPage WriteThe page write mode of the CAT28LV65 (essentially an extended BYTE WRITE mode) allows from 1 to 32 bytes of data to be programmed within a single EEPROM write cycle. This effectively reduces the byte-write time by a factor of 32.Following an initial WRITE operation (WE pulsed low, for t WP , and then high) the page write mode can begin by issuing sequential WE pulses, which load the address and data bytes into a 32 byte temporary buffer. The page address where data is to be written, specified by bits A 5to A 12, is latched on the last falling edge of WE . Each byte within the page is defined by address bits A 0 to A 4(which can be loaded in any order) during the first and subsequent write cycles. Each successive byte load cycle must begin within t BLC MAX of the rising edge of the preceding WE pulse. There is no page write window limitation as long as WE is pulsed low within t BLC MAX .Upon completion of the page write sequence, WE must stay high a minimum of t BLC MAX for the internal auto-matic program cycle to commence. This programming cycle consists of an erase cycle, which erases any data that existed in each addressed cell, and a write cycle,which writes new data back into the cell. A page write will only write data to the locations that were addressed and will not rewrite the entire page.BYTE 0BYTE 1BYTE 2BYTE nBYTE n+1BYTE n+2Figure 5. Byte Write Cycle [CE Controlled]CAT28LV658Doc. No. 1024, Rev. DWECEOEI/O 6DATA PollingDATA polling is provided to indicate the completion of write cycle. Once a byte write or page write cycle is initiated, attempting to read the last byte written will output the complement of that data on I/O 7 (I/O 0–I/O 6are indeterminate) until the programming cycle is com-plete. Upon completion of the self-timed write cycle, all I/O’s will output true data during a read cycle.Toggle BitIn addition to the DATA Polling feature, the device offers an additional method for determining the completion of a write cycle. While a write cycle is in progress, readingdata from the device will result in I/O 6 toggling between one and zero. However, once the write is complete, I/O 6stops toggling and valid data can be read from the device.Ready/BUSY (RDY/BUSY )The RDY/BUSY pin is an open drain output which indicates device status during programming. It is pulled low during the write cycle and released at the end of programming. Several devices may be OR-tied to the same RDY/BUSY line.Figure 7. DATA PollingFigure 8. Toggle BitNote:(1)Beginning and ending state of I/O 6 is indeterminate.CAT28LV659Doc. No. 1024, Rev. DHARDWARE DATA PROTECTIONThe following is a list of hardware data protection fea-tures that are incorporated into the CAT28LV65.(1)V CC sense provides for write protection when V CCfalls below 2.0V min.(2) A power on delay mechanism, t INIT (see AC charac-teristics), provides a 5 to 10 ms delay before a write sequence, after V CC has reached 2.40V min.(3)Write inhibit is activated by holding any one of OElow, CE high or WE high.(4)Noise pulses of less than 20 ns on the WE or CEinputs will not result in a write cycle.SOFTWARE DATA PROTECTIONThe CAT28LV65 features a software controlled data protection scheme which, once enabled, requires a data algorithm to be issued to the device before a write can be performed. The device is shipped from Catalyst with the software protection NOT ENABLED (the CAT28LV65 is in the standard operating mode).Figure 9.Write Sequence for Activating SoftwareData ProtectionFigure 10.Write Sequence for DeactivatingSoftware Data ProtectionSOFTWARE DATAPROTECTION ACTIVATED(12)Note:(1)Write protection is activated at this point whether or not any more writes are completed. Writing to addresses must occur within t BLCMax., after SDP activation.(1)CAT28LV6510Doc. No. 1024, Rev. DTo activate the software data protection, the device must be sent three write commands to specific addresses with specific data (Figure 9). This sequence of commands (along with subsequent writes) must adhere to the page write timing specifications (Figure 11). Once this is done,all subsequent byte or page writes to the device must be preceded by this same set of write commands. The data protection mechanism is activated until a deactivate sequence is issued regardless of power on/off transi-tions. This gives the user added inadvertent write pro-tection on power-up in addition to the hardware protec-tion provided.To allow the user the ability to program the device with an EEPROM programmer (or for testing purposes) there is a software command sequence for deactivating the data protection. The six step algorithm (Figure 10) will reset the internal protection circuitry, and the device will return to standard operating mode (Figure 12 provides reset timing). After the sixth byte of this reset sequence has been issued, standard byte or page writing can commence.Figure 11. Software Data Protection TimingFigure 12.

Its 256K of memory is organized as 32,768 words by 8 bits. Manufac-tured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 200 ns with power dissipation of just 54 mW. When the device is deselected, the CMOS standby current is less than 200 µA.PLCC – Top ViewPin ConfigurationsPin Name Function A0 - A14Addresses CE Chip Enable OE Output Enable WE Write Enable I/O0 - I/O7Data Inputs/Outputs NC No Connect DCDon’t ConnectPDIP , SOIC – Top ViewNote:1.Note: PLCC package pins 1 and 17are DON’T CONNECT.TSOP – Top View2AT28BV2560273H–PEEPR–10/04The AT28BV256 is accessed like a Static RAM for the read or write cycle without the need for external components. The device contains a 64-byte page register to allow writing of up to 64 bytes simultaneously. During a write cycle, the addresses and 1 to 64 bytes of data are inter-nally latched, freeing the address and data bus for other operations. Following the initiation of a write cycle, the device will automatically write the latched data using an internal control write cycle has been detected a new access for a read or w rite c an begin.Atmel’s AT28BV256 has additional features to ensure high quality and manufacturability. The device utilizes internal error correction for extended endurance and improved data retention characteristics. An optional software data protection mechanism is available to guard against inadvertent writes. The device also includes an extra 64 bytes of EEPROM for device identifi-cation or tracking.Block DiagramAbsolute Maximum Ratings*Temperature under Bias ................................-55°C to +125°C *NOTICE:Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent dam-age to the device.

Once a programming operation has been initiated and for the duration of t WC , a read operation will effectively be a polling operation.PAGE WRITE: The page write operation of the AT28BV256 allows 1 to 64 bytes of data to be written into the device during a single internal programming period. A page write operation is initiated in the same manner as a byte write; the first byte written can then be followed by 1 to 63 additional bytes. Each successive byte must be written within 150 µs (t BLC ) of the previous byte. If the t BLC limit is exceeded the AT28BV256 will cease accepting data and commence the internal programming operation. All bytes during a page write operation must reside on the during the page write operation, A6 - A14 must be the same.The A0 to A5 inputs are used to specify which bytes within the page are to be written. The bytes may be loaded in any order and may be altered within the same load period. Only bytes which are specified for writing will be written; unnecessary cycling of other bytes within the page does not occur.During a byte or page write cycle, an attempted read of the last byte written will result in the complement of the written data to be presented on I/O7. Once the write cycle has been com-begin at anytime during the write cycle.TOGGLE BIT:determining the end of a write cycle. During the write operation, successive attempts to read data from the device will result in I/O6 toggling between one and zero. Once the write has completed, I/O6 will stop toggling and valid data will be read. Reading the toggle bit may begin at any time during the write cycle.DATA PROTECTION: If precautions are not taken, inadvertent writes may occur during transi-tions of the host system power supply. Atmel has incorporated both hardware and software features that will protect the memory against inadvertent writes.HARDWARE PROTECTION: Hardware features protect against inadvertent writes to the AT28BV256 in the following ways: (a) V CC power-on delay – once V CC has reached 1.8V (typ-ical) the device will automatically time out 10 ms (typical) before allowing a write; (b) write SOFTWARE DATA PROTECTION: A software-controlled data protection feature has been implemented on the AT28BV256. Software data protection (SDP) helps prevent inadvertent writes from corrupting the data in the device. SDP can prevent inadvertent writes during power-up and power-down as well as any other potential periods of system instability.The AT28BV256 can only be written using the software data protection feature. A series of three write commands to specific addresses with specific data must be presented to the device before writing in the byte or page mode. The same three write commands must begin each write operation. All software write commands must obey the page mode write timing4AT28BV2560273H–PEEPR–10/04specifications. The data in the 3-byte command sequence is not written to the device; the address in the command sequence can be utilized just like any other location in the device.Any attempt to write to the device without the 3-byte sequence will start the internal write tim-ers. No data will be written to the device; however, for the duration of t WC , read operations will effectively be polling operations.DEVICE IDENTIFICATION: An extra 64 bytes of EEPROM memory are available to the user for device identification.
