2 at49bv3218(t) 2452d?flash?03/02 note: *either pin 13 or pin 14 (tsop package) or ball b3 or ball c4 (cbga package) can be connected to v pp or both pins can be unconnected. the device powers on in the read mode. command sequences are used to place the device in other operation modes such as program and erase. the device has the capa- bility to protect the data in any sector (see sector lockdown section). the device is segmented into two memory planes. reads from memory plane b may be performed even while program or erase functions are being executed in memory plane a and vice versa. this operation allows improved system performance by not requiring the system to wait for a program or erase operation to complete before a read is per- formed. to further increase the flexibility of the device, it contains an erase suspend feature. this feature will put the erase on hold for any amount of time and let the user read data from or program data to any of the remaining sectors within the same memory plane. there is no reason to suspend the erase operation if the data to be read is in the other memory plane. the end of a program or an erase cycle is detected by the ready/busy pin, data polling or by the toggle bit. a six-byte command (enter single pulse program mode) sequence 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 con- trol lines are required for writing into the device. this mode (single pulse byte/word program) is exited by powering down the device, or by pulsing the reset pin low for a minimum of 500 ns and then bringing it back to v cc . erase and erase suspend/resume commands will not work while in this mode; if entered they will result in data being pro- grammed 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. the byte pin controls whether the device data i/o pins operate in the byte or word con- figuration. if the byte pin is set at logic ?1?, the device is in word configuration, i/o0 - i/o15 are active and controlled by ce and oe .ifthebyte pin is set at logic ?0?, the device is in byte configuration, and only data i/o pins i/o0 - i/o7 are active and con- trolled by ce and oe . the data i/o pins i/o8 - i/o14 are tri-stated, and the i/o15 pin is used as an input for the lsb (a-1) address function. cbga top view a b c d e f g h a3 a4 a2 a1 a0 ce oe vss a7 a17 a6 a5 i/o0 i/o8 i/o9 i/o1 rdy/busy nc* a18 a20 i/o2 i/o10 i/o11 i/o3 we reset vpp* a19 i/o5 i/o12 vcc i/o4 a9 a8 a10 a11 i/o7 i/o14 i/o13 i/o6 a13 a12 a14 a15 a16 byte i/o15/a-1 vss 1 2 3456 tsop top view type 1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 a15 a14 a13 a12 a11 a10 a9 a8 a19 a20 we reset vpp* nc* rdy/busy a18 a17 a7 a6 a5 a4 a3 a2 a1 a16 byte gnd i/o15/a-1 i/o7 i/o14 i/o6 i/o13 i/o5 i/o12 i/o4 vcc i/o11 i/o3 i/o10 i/o2 i/o9 i/o1 i/o8 i/o0 oe gnd ce a0

4 at49bv3218(t) 2452d ? flash ? 03/02 device operation read: the at49bv3218(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. command sequences: when the device is first powered on it will be reset to the read or standby mode, depending upon the state of the control line inputs. in order to perform other device functions, a series of command sequences are entered into the device. the command sequences are shown in the command definitions table (i/o8 - i/o15 are don ? t care inputs for the command codes). the command sequences are written by applying a low pulse on the we or ce input with ce or we low (respectively) and oe high. the address is latched on the falling edge of ce or we , whichever occurs last. the data is latched by the first rising edge of ce or we . standard microprocessor write timings are used. the address locations used in the command sequences are not affected by entering the command sequences. 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 input 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 the read or standby mode, depending upon the state of the control inputs. erasure: before a byte/word can be reprogrammed, it must be erased. the erased state of memory bits is a logical ? 1 ? . the entire device can be erased by using the chip erase com- mand or individual sectors can be erased by using the sector erase command. chip erase: the entire device can be erased at one time by using the six-byte chip erase software code. after the chip erase has been initiated, the device will internally time the erase operation so that no external clocks are required. the maximum time to erase the chip is t ec . if the sector lockdown has been enabled, the chip erase will not erase the data in the sector that has been locked out; it will erase only the unprotected sectors. after the chip erase, the device will return to the read or standby mode. sector erase: as an alternative to a full chip erase, the device is organized into 71 sec- tors (sa0 - sa70) that can be individually erased. the sector erase command is a six-bus cycle operation. the sector address is latched on the falling we edge of the sixth cycle while the 30h data input command is latched on the rising edge of we . the sector erase starts after the rising edge of we of the sixth cycle. the erase operation is internally controlled; it will automatically time to completion. the maximum time to erase a section is t sec . when the sec- tor programming lockdown feature is not enabled, the sector will erase (from the same sector erase command). an attempt to erase a sector that has been protected will result in the oper- ation terminating in 2 s. byte/word programming: once a memory block is erased, it is programmed (to a logi- cal ? 0 ? ) on a byte-by-byte or on a word-by-word basis. programming is accomplished via the internal device command register and is a four-bus cycle operation. the device will automati- cally generate the required internal program pulses. any commands written to the chip during the embedded programming cycle will be ignored. if a hardware reset happens during programming, the data at the location being programmed will be corrupted. please note that a data ? 0 ? cannot be programmed back to a ? 1 ? ;onlyerase operations can convert ? 0 ? sto ? 1 ? s. programming is completed after the specified t bp cycle time. the data polling feature or the toggle bit feature may be used to indicate the end of a program cycle.
5 at49bv3218(t) 2452d ? flash ? 03/02 sector lockdown: each sector has a programming lockdown feature. this feature pre- vents programming of data in the designated sectors once the feature has been enabled. these sectors can contain secure code that is used to bring up the system. enabling the lock- down feature will allow the boot code to stay in the device while data in the rest of the device is updated. this feature does not have to be activated; any sector ? s usage as a write protected region is optional to the user. at power-up or reset all sectors are unlocked. to activate the lockdown for a specific sector, the six-bus cycle sector lockdown command must be issued. once a sector has been locked down, the contents of the sector is read-only and cannot be erased or programmed. sector lockdown detection: a software method is available to determine if program- ming of a sector is locked down. when the device is in the software product identification mode (see software product identification entry and exit sections) a read from address loca- tion 00002h within a sector will show if programming the sector is locked down. if the data on i/o0 is low, the sector can be programmed; if the data on i/o0 is high, the program lockdown feature has been enabled and the sector cannot be programmed. the software product identi- fication exit code should be used to return to standard operation. sector lockdown override: the only way to unlock a sector that is locked down is through reset or power-up cycles. after power-up or reset, the content of a sector that is locked down can be erased and reprogrammed. erase suspend/erase resume: theerasesuspendcommandallowsthesystemto interrupt a sector erase operation and then program or read data from a different sector within the same plane. since this device has a dual-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 the other plane. after the erase suspend command is given, the device requires a maximum time of 15 s 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 (determined by a20 - a19). the device also supports an erase sus- pend 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 sus- pend and a sector erase suspend are the same. product identification: the product identification mode identifies the device and man- ufacturer as atmel. it may be accessed by hardware or software operation. the hardware operation mode can be used by an external programmer to identify the correct programming algorithm for the atmel product. for details, see ? operating modes ? on page 13 (for hardware operation) or ? software product identification entry/exit ? on page 20. the manufacturer and device codes are the same for both modes. 128-bit protection register: the device 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 repro- grammed. 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 7. 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
6 at49bv3218(t) 2452d ? flash ? 03/02 bus cycle. all other data bits during the fourth bus cycle are don ? t cares. please see the ? pro- tection register addressing table ? on page 8 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 reading the protec- tion register, the product id exit command must be given prior to performing any other operation. data polling: the at49bv3218(t) features data polling to indicate the end of a program cycle. during a program cycle an attempted read of the last byte/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 opera- tion, 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 21 for more details. toggle bit: in addition to data polling, the at49bv3218(t) provides another method for determining the end of a program or erase cycle. during a program or erase operation, suc- cessive attempts to read data from the same memory plane 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. an additional toggle bit is available on i/o2, which can be used in conjunction with the toggle bit that is available on i/o6. while a sector is erase suspended, a read or a program operation from the suspended sector will result in the i/o2 bit toggling. please see ? status bit table ? on page 21 for more details. rdy/busy : an open-drain ready/busy output pin provides another method of detecting the end of a program or erase operation. rdy/busy is actively pulled low during the internal pro- gram and erase cycles and is released at the completion of the cycle. the open-drain connection allows for or-tying of several devices to the same rdy/busy line. hardware data protection: the hardware data protection feature protects against inadvertent programs to the at49bv3218(t) in the following ways: (a) v cc sense: if v cc is below 1.8v (typical), the program function is inhibited. (b) v cc power-on delay: once v cc has reached the v cc sense level, the device will automatically time out 10 ms (typical) before pro- gramming. (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. input levels: while operating with a 2.65v to 3.3v 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 only be driven from 0 to v cc +0.6v.
