Description The AT49BV6416(T) is a 2.7-volt 64-megabit Flash memory. The memory is divided into multiple sectors and planes for erase operations. The device can be read or reprogrammed off a single 2.7V power supply, making it ideally suited for in-system programming. The output voltage can be separately controlled down to 2.2V through the VCCQ supply pin. The device can operate in the asynchronous or page read mode. The AT49BV6416(T) is divided into four memory planes. A read operation can occur in any of the three planes which is not being programmed or erased. This concurrent operation allows improved system performance by not requiring the system to wait for a program or erase operation to complete before a read is performed. To further increase the flexibility of the device, it contains an Erase Suspend and Program Suspend feature. This feature will put the erase or program on hold for any amount of time and let the user read data from or program data to any of the remaining sectors. There is no reason to suspend the erase or program operation if the data to be read is in another memory plane. The end of program or erase is detected by Data Polling or toggle bit. 3451C–FLASH–2/05 The VPP pin provides data protection and faster programming times. When the VPP input is below 0.7V, the program and erase functions are inhibited. When VPP is at 1.65V or above, normal program and erase operations can be performed. With VPP at 10.0V, the program (dualword program command) operation is accelerated. A six-byte command (Enter Single Pulse Program Mode) to remove the requirement of entering the three-byte program sequence is offered to further improve programming time. After entering the six-byte code, only single pulses on the write control lines are required for writing into the device. This mode (Single Pulse Word Program) is exited by powering down the device, by taking the RESET pin to GND or by a high-to-low transition on the V PP input. Erase, Erase Suspend/Resume, Program Suspend/Resume and Read Reset commands will not work while in this mode; if entered they will result in data being programmed into the device. It is not recommended that the six-byte code reside in the software of the final product but only exist in external programming code. 2.

Device Operation 3.1 Command Sequences The device powers on in the read mode. Command sequences are used to place the device in other operating modes such as program and erase. After the completion of a program or an erase cycle, the device enters the read mode. The command sequences are written by applying a low pulse on the WE input with CE low and OE high or by applying a low-going pulse on the CE input with WE low and OE high. The address is latched on the falling edge of the WE or CE pulse whichever occurs first. Valid data is latched on the rising edge of the WE or the CE pulse, whichever occurs first. The addresses used in the command sequences are not affected by entering the command sequences. 3.2 Asynchronous Read The AT49BV6416(T) is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins are asserted on the outputs. The outputs are put in the high impedance state whenever CE or OE is high. This dual-line control gives designers flexibility in preventing bus contention. 3.3 Page Read The page read operation of the device is controlled by CE and OE inputs. The page size is four words. The first word access of the page read is the same as the asynchronous read. The first word is read at an asynchronous speed of 70 ns. Once the first word is read, toggling A0 and A1 will result in subsequent reads within the page being output at a speed of 20 ns. The “Page Read Cycle Waveform” is shown on page 21. 3.4 Reset A RESET input pin is provided to ease some system applications. When RESET is at a logic high level, the device is in its standard operating mode. A low level on the RESET pin halts the present device operation and puts the outputs of the device in a high-impedance state. When a high level is reasserted on the RESET pin, the device returns to read or standby mode, depending upon the state of the control pins. 3.5 Erase Before a word can be reprogrammed it must be erased. The erased state of the memory bits is a logical “1”. The entire memory can be erased by using the Chip Erase command or individual planes or sectors can be erased by using the Plane Erase or Sector Erase commands. 3.5.1 Chip Erase Chip Erase is a six-bus cycle operation. The automatic erase begins on the rising edge of the last WE pulse. Chip Erase does not alter the data of the protected sectors. After the full chip erase the device will return back to the read mode. The hardware reset during Chip Erase will stop the erase but the data will be of unknown state. Any command during Chip Erase except Erase Suspend will be ignored. 3 3451C–FLASH–2/05 3.5.2 Plane Erase As a alternative to a full chip erase, the device is organized into four planes that can be individually erased. The plane erase command is a six-bus cycle operation. The plane whose address is valid at the sixth falling edge of WE will be erased. The plane erase command does not alter the data in protected sectors. 3.5.3 Sector Erase As an alternative to a full chip erase or a plane erase, the device is organized into multiple sectors that can be individually erased. The Sector Erase command is a six-bus cycle operation. The sector whose address is valid at the sixth falling edge of WE will be erased provided the given sector has not been protected. 3.6 Word Programming The device is programmed on a word-by-word basis. Programming is accomplished via the internal device command register and is a four-bus cycle operation. The programming address and data are latched in the fourth cycle. The device will automatically generate the required internal programming pulses. Please note that a “0” cannot be programmed back to a “1”; only erase operations can convert “0”s to “1”s. 3.7 Flexible Sector Protection The AT49BV6416(T) offers two sector protection modes, the Softlock and the Hardlock. The Softlock mode is optimized as sector protection for sectors whose content changes frequently. The Hardlock protection mode is recommended for sectors whose content changes infrequently. Once either of these two modes is enabled, the contents of the selected sector is read-only and cannot be erased or programmed. Each sector can be independently programmed for either the Softlock or Hardlock sector protection mode. At power-up and reset, all sectors have their Softlock protection mode enabled. 3.7.1 Softlock and Unlock The Softlock protection mode can be disabled by issuing a two-bus cycle Unlock command to the selected sector. Once a sector is unlocked, its contents can be erased or programmed. To enable the Softlock protection mode, a six-bus cycle Softlock command must be issued to the selected sector. 3.7.2 Hardlock and Write Protect (WP) The Hardlock sector protection mode operates in conjunction with the Write Protection (WP) pin. The Hardlock sector protection mode can be enabled by issuing a six-bus cycle Hardlock software command to the selected sector. The state of the Write Protect pin affects whether the Hardlock protection mode can be overridden. • When the WP pin is low and the Hardlock protection mode is enabled, the sector cannot be unlocked and the contents of the sector is read-only. • When the WP pin is high, the Hardlock protection mode is overridden and the sector can be unlocked via the Unlock command. To disable the Hardlock sector protection mode, the chip must be either reset or power cycled. 4 AT49BV6416(T) 3451C–FLASH–2/05 AT49BV6416(T) Table 3-1.

The notation [X, Y, Z] denotes the locking state of a sector. The current locking state of a sector is defined by the state of WP and the two bits of the sector-lock status D[1:0]. 3.7.3 Sector Protection Detection A software method is available to determine if the sector protection Softlock or Hardlock features are enabled. When the device is in the software product identification mode a read from the I/O0 and I/O1 at address location 00002H within a sector will show if the sector is unlocked, softlocked, or hardlocked. 5 3451C–FLASH–2/05 Table 3-2. 3.8 Sector Protection Status I/O1 I/O0 Sector Protection Status 0 0 Sector Not Locked 0 1 Softlock Enabled 1 0 Hardlock Enabled 1 1 Both Hardlock and Softlock Enabled Program/Erase Status The device provides several bits to determine the status of a program or erase operation: I/O2, I/O3, I/O5, I/O6, and I/O7. All other status bits are don’t care. The “Status Bit Table” on page 11 and the following four sections describe the function of these bits. To provide greater flexibility for system designers, the AT49BV6416(T) contains a programmable configuration register. The configuration register allows the user to specify the status bit operation. The configuration register can be set to one of two different values, “00” or “01”. If the configuration register is set to “00”, the part will automatically return to the read mode after a successful program or erase operation. If the configuration register is set to a “01”, a Product ID Exit command must be given after a successful program or erase operation before the part will return to the read mode. It is important to note that whether the configuration register is set to a “00” or to a “01”, any unsuccessful program or erase operation requires using the Product ID Exit command to return the device to read mode. The default value (after power-up) for the configuration register is “00”. Using the four-bus cycle set configuration register command as shown in the “Command Definition Table” on page 12, the value of the configuration register can be changed. Voltages applied to the reset pin will not alter the value of the configuration register. The value of the configuration register will affect the operation of the I/O7 status bit as described below. 3.8.1 Data Polling The AT49BV6416(T) features Data Polling to indicate the end of a program cycle. If the status configuration register is set to a “00”, during a program cycle an attempted read of the last word loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been completed, true data is valid on all outputs and the next cycle may begin. During a chip or sector erase operation, an attempt to read the device will give a “0” on I/O7. Once the program or erase cycle has completed, true data will be read from the device. Data Polling may begin at any time during the program cycle. Please see “Status Bit Table” on page 11 for more details. If the status bit configuration register is set to a “01”, the I/O7 status bit will be low while the device is actively programming or erasing data. I/O7 will go high when the device has completed a program or erase operation. Once I/O7 has gone high, status information on the other pins can be checked. The Data Polling status bit must be used in conjunction with the erase/program and VPP status bit as shown in the algorithm in Figures 3-2 and 3-3 on page 9. 3.8.2 Toggle Bit In addition to Data Polling, the AT49BV6416(T) provides another method for determining the end of a program or erase cycle. During a program or erase operation, successive attempts to read data from the memory will result in I/O6 toggling between one and zero. Once the program cycle has completed, I/O6 will stop toggling and valid data will be read. Examining the toggle bit may begin at any time during a program cycle. Please see “Status Bit Table” on page 11 for more details. 6 AT49BV6416(T) 3451C–FLASH–2/05 AT49BV6416(T) The toggle bit status bit should be used in conjunction with the erase/program and VPP status bit as shown in the algorithm in Figures 3-4 and 3-5 on page 10. 3.8.3 Erase/Program Status Bit The device offers a status bit on I/O5 that indicates whether the program or erase operation has exceeded a specified internal pulse count limit. If the status bit is a “1”, the device is unable to verify that an erase or a word program operation has been successfully performed. The device may also output a “1” on I/O5 if the system tries to program a “1” to a location that was previously programmed to a “0”. Only an erase operation can change a “0” back to a “1”. If a program (Sector Erase) command is issued to a protected sector, the protected sector will not be programmed (erased). The device will go to a status read mode and the I/O5 status bit will be set high, indicating the program (erase) operation did not complete as requested. Once the erase/program status bit has been set to a “1”, the system must write the Product ID Exit command to return to the read mode. The erase/program status bit is a “0” while the erase or program operation is still in progress. Please see “Status Bit Table” on page 11 for more details. 3.8.4 VPP Status Bit The AT49BV6416(T) provides a status bit on I/O3 that provides information regarding the voltage level of the VPP pin. During a program or erase operation, if the voltage on the VPP pin is not high enough to perform the desired operation successfully, the I/O3 status bit will be a “1”. Once the VPP status bit has been set to a “1”, the system must write the Product ID Exit command to return to the read mode. On the other hand, if the voltage level is high enough to perform a program or erase operation successfully, the VPP status bit will output a “0”. Please see “Status Bit Table” on page 11 for more details. 3.9 Erase Suspend/Erase Resume The Erase Suspend command allows the system to interrupt a sector erase operation and then program or read data from a different sector within the same plane. Since this device has a multiple plane architecture, there is no need to use the erase suspend feature while erasing a sector when you want to read data from a sector in another plane. After the Erase Suspend command is given, the device requires a maximum time of 15 µs to suspend the erase operation. After the erase operation has been suspended, the plane that contains the suspended sector enters the erase-suspend-read mode. The system can then read data or program data to any other sector within the device. An address is not required during the Erase Suspend command. During a sector erase suspend, another sector cannot be erased. To resume the sector erase operation, the system must write the Erase Resume command. The Erase Resume command is a one-bus cycle command, which does require the plane address. The device also supports an erase suspend during a complete chip erase. While the chip erase is suspended, the user can read from any sector within the memory that is protected. The command sequence for a chip erase suspend and a sector erase suspend are the same. 3.10 Program Suspend/Program Resume The Program Suspend command allows the system to interrupt a programming operation and then read data from a different word within the memory. After the Program Suspend command is given, the device requires a maximum of 10 µs to suspend the programming operation. After the programming operation has been suspended, the system can then read from any other word within the device. An address is not required during the program suspend operation. To resume the programming operation, the system must write the Program Resume command. The program suspend and resume are one-bus cycle commands. The command sequence for the 7 3451C–FLASH–2/05 erase suspend and program suspend are the same, and the command sequence for the erase resume and program resume are the same. 3.11 128-Bit Protection Register The AT49BV6416(T) contains a 128-bit register that can be used for security purposes in system design. The protection register is divided into two 64-bit blocks. The two blocks are designated as block A and block B. The data in block A is non-changeable and is programmed at the factory with a unique number. The data in block B is programmed by the user and can be locked out such that data in the block cannot be reprogrammed. To program block B in the protection register, the four-bus cycle Program Protection Register command must be used as shown in the “Command Definition Table” on page 12. To lock out block B, the four-bus cycle lock protection register command must be used as shown in the Command Definition table. Data bit D1 must be zero during the fourth bus cycle. All other data bits during the fourth bus cycle are don’t cares. To determine whether block B is locked out, the status of Block B Protection command is given. If data bit D1 is zero, block B is locked. If data bit D1 is one, block B can be reprogrammed. Please see the “Protection Register Addressing Table” on page 13 for the address locations in the protection register. To read the protection register, the Product ID Entry command is given followed by a normal read operation from an address within the protection register. After determining whether block B is protected or not or reading the protection register, the Product ID Exit command must be given prior to performing any other operation. 3.12 Common Flash Interface (CFI) Common Flash Interface (CFI) is a published, standardized data structure that may be read from a Flash device. CFI allows system software to query the installed device to determine the configurations, various electrical and timing parameters, and functions supported by the device. CFI is used to allow the system to learn how to interface to the Flash device most optimally. The two primary benefits of using CFI are ease of upgrading and second source availability. The command to enter the CFI Query mode is a one-bus cycle command which requires writing data 98h to address 55h. The CFI Query command can be written when the device is ready to read data or can also be written when the part is in the product ID mode. Once in the CFI Query mode, the system can read CFI data at the addresses given in the “Common Flash Interface Definition Table” on page 25. To exit the CFI Query mode, the product ID exit command must be given. 3.13 Hardware Data Protection Hardware features protect against inadvertent programs to the AT49BV6416(T) in the following ways: (a) VCC sense: if VCC is below 1.8V (typical), the program function is inhibited. (b) VCC power-on delay: once VCC has reached the VCC sense level, the device will automatically timeout 10 ms (typical) before programming. (c) Program inhibit: holding any one of OE low, CE high or WE high inhibits program cycles. (d) Noise filter: pulses of less than 15 ns (typical) on the WE or CE inputs will not initiate a program cycle. (e) VPP is less than VILPP. 3.14 Input Levels While operating with a 2.7V to 3.6V power supply, the address inputs and control inputs (OE, CE and WE) may be driven from 0 to 5.5V without adversely affecting the operation of the device. The I/O lines can be driven from 0 to VCCQ + 0.6V. 3.15 Output Levels For the AT49BV6416(T), output high levels are equal to VCCQ - 0.1V (not VCC). For 2.7V to 3.6V output levels, VCCQ must be tied to VCC. 8 AT49BV6416(T) 3451C–FLASH–2/05 Figure 3-2. Data Polling Algorithm (Configuration Register = 00) Figure 3-3.

Since A11 is a Don’t Care, AAA can be replaced with 2AA. 3. Either one of the Product ID Exit commands can be used. 4. SA = sector address. Any word address within a sector can be used to designate the sector address (see pages 14 - 17 for details). 5. Once a sector is in the Hardlock protection mode, it cannot be disabled unless the chip is reset or power cycled. 6. PA is the plane address (A21 - A20). 7. During the fourth bus cycle, the manufacturer code is read from address PA+00000H, the device code is read from address PA+00001H, and the data in the protection register is read from addresses 000081H - 000088H. PA (A21 - A20) must specify the same plane address as specified in the third bus cycle. 8. The fast programming option enables the user to program two words in parallel only when VPP = 10V. The addresses, Addr0 and Addr1, of the two words, DIN0 and DIN1, must only differ in address A0. This command should be used for manufacturing purpose only. 9. If data bit D1 is “0”, block B is locked. If data bit D1 is “1”, block B can be reprogrammed. 10. The default state (after power-up) of the configuration register is “00”. 11.

Revision History Revision No. History Revision A – March 2004 • Initial Release Revision B – November 2004 • • • • • • Removed “Preliminary” from the datasheet. Modified Plane Erase text on page 3. Modified note 7 and added notes 11, 12, and 13 on page 11. Removed note 1 on page 12. Changed SA102 from plane D to plane C on page 14. Changed the ISB1 spec to 35 µA. Revision C – January 2005 • • Converted datasheet to New Template. Changed the VPP value to 9.5 ± 0.5V in the text, table on page 12, and CFI table. VPP text also changed to show that a high voltage on VPP improves only the programming time. Added Green Package (Pb/Halide-free) Option in the Ordering Information section. • 29 3451C–FLASH–2/05 Atmel Corporation 2325 Orchard Parkway San Jose, CA 95131, USA Tel: 1(408) 441-0311 Fax: 1(408) 487-2600 Regional Headquarters Europe Atmel Sarl Route des Arsenaux 41 Case Postale 80 CH-1705 Fribourg Switzerland Tel: (41) 26-426-5555 Fax: (41) 26-426-5500 Asia Room 1219 Chinachem Golden Plaza 77 Mody Road Tsimshatsui East Kowloon Hong Kong Tel: (852) 2721-9778 Fax: (852) 2722-1369 Japan 9F, Tonetsu Shinkawa Bldg. 1-24-8 Shinkawa Chuo-ku, Tokyo 104-0033 Japan Tel: (81) 3-3523-3551 Fax: (81) 3-3523-7581 Atmel Operations Memory 2325 Orchard Parkway San Jose, CA 95131, USA Tel: 1(408) 441-0311 Fax: 1(408) 436-4314 RF/Automotive Theresienstrasse 2 Postfach 3535 74025 Heilbronn, Germany Tel: (49) 71-31-67-0 Fax: (49) 71-31-67-2340 Microcontrollers 2325 Orchard Parkway San Jose, CA 95131, USA Tel: 1(408) 441-0311 Fax: 1(408) 436-4314 La Chantrerie BP 70602 44306 Nantes Cedex 3, France Tel: (33) 2-40-18-18-18 Fax: (33) 2-40-18-19-60 ASIC/ASSP/Smart Cards 1150 East Cheyenne Mtn.
