flash memory k8d6x16utm / k8d6x16ubm revision 1.5 march 2005 13 product introduction the k8d6316u is an 64mbit (67,108,864 bits ) nor-type flash memory. the device feat ures single voltage power supply operating within the range of 2.7v to 3.6v. the device is programmed by using the channel hot electron (c he) injection mechanism which is used to program eproms. the device is eras ed electrically by using fo wler-nordheim tunneling mechani sm. to provide highly flex- ible erase and program capability, the device adapts a block memory architecture that divides its memory array into 135 blocks (64- kbyte x 127 , 8-kbyte x 8). programming is done in units of 8 bits (byte) or 16 bits (word). all bits of data in one or multipl e blocks can be erased simultaneously when th e device executes the erase operation. to prev ent the device from accidental erasing or ove r- writing the programmed data, 135 memory blocks can be hardware pr otected by the block group. byte /word modes are available for read operation. these modes can be selected via byte pin. the device provides read acce ss times of 70ns, 80ns and 90ns support- ing high speed microprocessors to operate without any wait states. the command set of k8d6316u is fully compatible with standar d flash devices. the device is controlled by chip enable (ce ), output enable (oe ) and write enable (we ). device operations are executed by select ive command codes. the command codes to be com- bined with addresses and data are sequentially written to the command registers using microprocessor write timing. the command codes serve as inputs to an internal state machine which controls the program/erase ci rcuitry. register contents also internall y latch addresses and data necessary to execute the program and erase oper ations. the k8d6316u is implemented with internal program/ erase algorithms to execute the program/erase operations. the in ternal program/erase algorithms are invoked by program/erase command sequences. the internal program algor ithm automatically programs and verifies data at specified addresses. the internal erase algorithm automatically pre-programs the memory cell whic h is not programmed and then executes the erase operation. the k8d6316u has means to indicate the status of completion of pr ogram/erase operations. the status can be indicated via the ry/by pin, data polling of dq7, or the toggle bit (dq6). once the operati ons have been completed, the device automatically resets itself to the read mode. the device requires only 14 ma as acti ve read current and 15 ma for program/erase operations. table 7. operations table operation ce oe we byte wp / acc a9 a6 a1 a0 dq15/ a-1 dq8/ dq14 dq0/ dq7 reset read word l l h h l/h a9 a6 a1 a0 dq15 d out d out h byte l l h l a9 a6 a1 a0 a-1 high-z d out h stand-by vcc 0.3v x x x (2) x x x x high-z high-z high-z (2) output disable l h h x l/h x x x x high-z high-z high-z h reset x x x x l/h x x x x high-z high-z high-z l write word l h l h (4) a9 a6 a1 a0 d in d in d in h byte l h l l a9 a6 a1 a0 a-1 high-z d in h enable block group protect (3) lhlxl/hxlhl x x d in v id enable block group unprotect (3) lhlx(4)xhhl x x d in v id temporary block group xxxx(4)xxxx x x x v id auto select manufacturer id (5) llhxl/hv id lll x x code (see table 9) h auto select device code (5) llhxl/hv id llh x x code (see table 9) h notes : 1. l = v il (low), h = v ih (high), v id = 8.5v~12.5v, d in = data in, d out = data out, x = don't care. 2. wp /acc and reset pin are asserted at vcc 0.3 v or vss 0.3 v in the stand-by mode. 3. addresses must be composed of the block address (a12 - a21). the block protect and unprotect operations may be implemented via programming equipment too. refer to the "block group protection and unprotection". 4. if wp /acc = v il, the two outermost boot blocks is protected. if wp /acc = v ih, the two outermost boot block protection depends on whether those blocks were last protected or unprotected using the met hod described in "block group protection and unprotection". if wp /acc = v hh , all blocks will be temporarily unprotected. 5. manufacturer and device codes may also be accessed via a command register write sequence. refer to table 9.
flash memory k8d6x16utm / k8d6x16ubm revision 1.5 march 2005 14 command definitions the k8d6316u operates by selecting and executing its operat ional modes. each operational mode has its own command set. in order to select a certain mode, a proper command with specific address and data sequences must be written into the command reg- ister. writing incorrect information which include address and data or writing an improper command will reset the device to the read mode. the defined valid register command sequences are stated in table 8. note that erase suspend (b0h) and erase resume (30h) commands are valid only while the bl ock erase operation is in progress. table 8. command sequences command sequence cycle 1st cycle 2nd cycle 3rd cycle 4th cycle 5th cycle 6th cycle word byte word byte word byte word byte word byte word byte read addr 1 ra data rd reset addr 1 xxxh data f0h autoselect manufacturer i d ( 2, 3 ) addr 4 555h aaah 2aah 555h da/ 555h da/ aaah da/ x00h da/ x00h data aah 55h 90h ech autoselect device code (2,3) addr 4 555h aaah 2aah 555h da/ 555h da/ aaah da/ x01h da/ x02h data aah 55h 90h (see table 9) autoselect block group protect verify (2,3) addr 4 555h aaah 2aah 555h da/ 555h da/ aaah ba / x02h ba/ x04h data aah 55h 90h (see table 9) auto select secode block factory protect verify (2,3) addr 4 555h aaah 2aah 555h da/ 555h da/ aaah da / x03h da/ x06h data aah 55h 90h (see table 9) enter secode b l o c k r e g i o n addr 3 555h aaah 2aah 555h 555h aaah data aah 55h 88h exit secode b l o c k r e g i o n addr 4 555h aaah 2aah 555h 555h aaah xxxh data aah 55h 90h 00h program addr 4 555h aaah 2aah 555h 555h aaah pa data aah 55h a0h pd unlock bypass addr 3 555h aaah 2aah 555h 555h aaah data aah 55h 20h unlock bypass program addr 2 xxxh pa data a0h pd unlock bypass reset addr 2 xxxh xxxh data 90h 00h chip erase addr 6 555h aaah 2aah 555h 555h aaah 555h aaah 2aah 555h 555h aaah data aah 55h 80h aah 55h 10h block erase addr 6 555h aaah 2aah 555h 555h aaah 555h aaah 2aah 555h ba data aah 55h 80h aah 55h 30h block erase suspend (4, 5) addr 1 xxxh data b0h block erase resume addr 1 xxxh data 30h cfi query (6) addr 1 55h aah data 98h

(k8d6316ut : ba133 and ba134, k8d6316ub : ba0 and ba1) when the wp /acc pin is asserted at v ih , the device reverts to whether the two outermost 8k byte boot blocks were last set to be protected or unprotected. that is, block protection or unprotec tion for these two blocks depends on whether they were last prot ected or unprotected using the method described in "block group protection/unprotection". recommend that the wp /acc pin must not be in the state of floating or unc onnected, or the device may be led to malfunction. temporary block group unprotect the protected blocks of the k8d6316u can be te mporarily unprotected by applying high voltage (v id = 8.5v~12.5v) to the reset pin. in this mode, previously protected blocks can be programmed or erased with the program or erase command routines. when the reset pin goes high (reset = v ih ), all the previously protected bloc ks will be protected again. if the wp /acc pin is asserted at v il , the two outermost boot blocks remain protected. reset program & erase operation v id v = v ih or v il at protected block ce we figure 10. temporary block group unprotect sequence secode(security code) block region the secode block feature provides a flash memory region to be stored unique and permanent identification code, that is, electro nic serial number (esn), customer code and so on. this is primar ily intended for customers who wish to use an electronic serial nu m- ber (esn) in the device with the esn protec ted against modification. once the secode bl ock region is protected, any further mod ifi- cation of that region is impossible. th is ensures the security of the esn once the product is shipped to the field. the secode block is factory locked or customer lockable. before the device is shipped, the factory locked secode block is writt en on the special code and it is protected. t he secode indicator bit (dq7) is permanently fixed at "1" and it is not changed. the customer lockable secode block is unprotected, ther efore it is programmed and erased. the secode indicator bit (dq7) of it is permanentl y fixed at "0" and it is not changed. but once it is protected, there is no procedure to unprotec t and modify the secode block. the secode block region is 64k bytes in length and is accessed through a new command sequence (see table 8). after the system has written the enter secode block command sequence, the sy stem may read the secode block region by using the same addresses of the boot blocks (8kbx8). t he k8d6316ut occupies the address of the byte mode 7f0000h to 7fffffh (word mode 3f8000h to 3fffffh) and the k8d6316ub type occupies the address of the byte mode 000000h to 00ffffh (word mode 000000h to 007fffh). this mode of operation continues until th e system issues the exit sec ode block command sequence, or until power is removed from the device. on power-up, or foll owing a hardware reset, the device reverts to read mode.
flash memory k8d6x16utm / k8d6x16ubm revision 1.5 march 2005 25 accelerated program operation accelerated program operation reduces the program time . this is one of two functions provided by the wp /acc pin. when the wp / acc pin is asserted as v hh , the device automatically enters the aforementi oned unlock bypass mode, temporarily unprotecting any protected blocks, and reduces the program operation time. the system would use a two-cycle program command sequence as required by the unlock bypass mode. removing v hh from the wp /acc pin returns the device to normal operation. recommend that the wp /acc pin must not be asserted at v hh except accelerated program operation, or the device may be damaged. in addition, the wp /acc pin must not be in the state of floating or unconnected, otherwise the device may be led to malfunc- tion. software reset the reset command provides that the bank is reseted to read mode or erase-suspend-read mode. the addresses are in don't care state. the reset command is vaild between the sequence cycles in an erase command sequence before erasing begins, or in a pro- gram command sequence before programming begins. this resets the bank in which was operating to read mode. if the device is be erasing or programming, the reset command is invalid until the operation is completed. also, the reset command is valid between the sequence cycles in an autoselect command sequence. in the autosele ct mode, the reset command returns the bank to read mode. if a bank entered the autoselect mode in the erase suspend mode, the reset command returns the bank to erase-suspend-read mode. if dq5 is high on erase or program operation, the reset command return the bank to read mode or erase-suspend-read mode if the bank was in the erase suspend state. hardware reset the k8d6316u offers a reset feature by driving the reset pin to v il . the reset pin must be kept low (v il ) for at least 500ns. when the reset pin is driven low, any operation in progress will be term inated and the internal state machine will be reset to the standby mode after 20 s. if a hardware reset occurs during a program operation, the data at that particular location will be lost. once the reset pin is taken high, the device requires 200ns of wake-up time until outputs are valid for read access. also, note that all the data output pins are tri-stated for the duration of the reset pulse. the reset pin may be tied to the system reset pin. if a system rese t occurs during the internal program and erase routine, the device will be automatically reset to the r ead mode ; this will enable the systems micr oprocessor to read the boot-up firmware from the flash memory. power-up protection to avoid initiation of a write cycle during vcc power-up, reset low must be asserted during power-up. after reset goes high, the device is reset to the read mode. low vcc write inhibit to avoid initiation of a write cycle duri ng vcc power-up and power-down, a write cycle is locked out for vcc less than 1.8v. if vcc < v lko (lock-out voltage), the command register and all internal program /erase circuits are disabled. under this condition the device will reset itself to the read mode. subsequent writes will be ignored until the vcc level is greater than v lko . it is the user s responsi- bility to ensure that the control pins are logically correct to prevent unint entional writes when vcc is above 1.8v. write pulse glitch protection noise pulses of less than 5ns(typical) on ce , oe , or we will not initiate a write cycle. logical inhibit writing is inhibited under any one of the following conditions : oe = v il , ce = v ih or we = v ih . to initiate a write, ce and we must be "0", while oe is "1". commom flash memory interface common flash momory interface is contrived to increase the compatibility of host system software. it provides the specific inf orma- tion of the device, such as memory size, byte/word configurati on, and electrical features. once this information has been obtai ned, the system software will know which command sets to use to enable flash writes, block erases , and control the flash component. when the system writes the cfi command(98h) to address 55h in word mode(or address aah in byte mode), the device enters the cfi mode. and then if the system writes the address shown in table 12, the system can read the cfi data. query data are always presented on the lowest-order data outputs(dq0-7) only. in word(x16) mode, the upper data outputs(dq8-15) is 00h. to terminate this operation, the system must write the reset command.

flash memory k8d6x16utm / k8d6x16ubm revision 1.5 march 2005 29 ry/by : ready/busy the k8d6316u has a ready / busy output that indicates either the completion of an op eration or the status of internal algorithms. if the output is low, the device is busy with either a program or an erase operation. if the output is high, the device is ready t o accept any read/write or erase operation. when the ry/ by pin is low, the device will not acc ept any additional program or erase commands with the exception of the erase suspend command. if the k8d6316u is placed in an erase suspend mode, the ry/ by output will be high. for programming, the ry/ by is valid (ry/ by = 0) after the rising edge of the fourth we pulse in the four write pulse sequence. for chip erase, ry/ by is also valid after the rising edge of we pulse in the six write pulse sequence. for block erase, ry/ by is also valid after the rising edge of the sixth we pulse. the pin is an open drain output, allowing two or more ready/ busy outputs to be or-tied. an appropriate pull-up resistor is required for proper operation. dq3 : block erase timer the status of the multi-block erase operation can be detected via the dq3 pin. dq3 will go high if 50 s of the block erase time win- dow expires. in this case, the internal erase routine will init iate the erase operation.therefore, the device will not accept f urther write commands until the erase operation is complete d. dq3 is low if the block erase time wi ndow is not expired. within the block era se time window, an additional block erase comm and (30h) can be accepted. to confirm that the block erase command has been accepted, the software may check the status of dq3 following each block erase command. dq2 : toggle bit 2 the device generates a toggling pulse in dq2 only if an internal erase routine or an erase suspend is in progress. when the dev ice executes the internal erase routine, dq2 toggles only if an eras ing block is read. although the in ternal erase routine is in th e exceeded time limits, dq2 toggles only if an erasing block in the exceeded time limits is read. when the device is in the erase suspend mode, dq2 toggles only if an address in the erasing bl ock is read. if a non-erasing block address is read during the er ase suspend mode, then dq2 will produce valid data. dq2 will go high if the user tries to program a non-erase suspend block while t he device is in the erase suspend mode. combination of the status in dq6 and dq2 can be used to distinguish the erase operation from the program operation. vcc f ready / busy open drain output device vss where i l is the sum of the input currents of all devices tied to the ready / busy ball. rp rp = vcc f (max.) - v ol (max.) i ol + i l = 3.2v 2.1ma + i l
