mx25v4006e rev. 1.4, nov. 14, 2013 5 general description the device features a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. the four bus signals are a clock input (sclk), a serial data i nput (si), a serial data output (so), and a chip select (cs#). serial access to the device is enabled by cs# input. when it is in dual output read mode, the si and so pins become sio0 and sio1 pins for data output. the device provides sequential read operation on whole chip. after program/erase command is issued, auto program/erase algorithms which program/erase and verify the speci - fed page or sector/block locations will be executed. program command is executed on byte basis, or page basis, or word basis for erase command is executes on sector, or block, or whole chip basis. to provide user with ease of interface, a status register is included to indicate the status of the chip. the status read command can be issued to detect completion status of a program or erase operation via wip bit. when the device is not in operation and cs# is high, it is put in standby mode. the device utilizes macronix's proprietary memory cell, which reliably stores memory contents even after 100,000 program and erase cycles. pin configurations symbol description cs# chip select si/sio0 serial data input (for 1 x i/o) / serial data input & output (for dual output

ready for the intended op - eration. 2. when incorrect command is inputted to this lsi, this lsi becomes standby mode and keeps the standby mode until next cs# falling edge. in standby mode, so pin of this lsi should be high-z. the cs# falling time needs to follow tchcl spec. 3. when correct command is inputted to this lsi, this lsi becomes active mode and keeps the active mode until next cs# rising edge. the cs# rising time needs to follow tclch spec. 4. input data is latched on the rising edge of serial clock(sclk) and data shifts out on the falling edge of sclk. the difference of serial peripheral interface mode 0 and mode 3 is shown as figure 1. 5. for the following instructions: rdid, rdsr, read, fast_read, rdsfdp, dread, res and rems the shift - ed-in instruction sequence is followed by a data-out sequence. after any bit of data being shifted out, the cs# can be high. for the following instructions: wren, wrdi, wrsr, se, be, ce, pp, rdp and dp the cs# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed. 6. during the progress of w rite status register, program, erase operation, to access the memory array is neglect - ed and not affect the current operation of write status register, program, erase. figure 1. serial peripheral interface modes supported sclk msb cpha si 0 1 cpol 0 (serial mode 0) (serial mode 3) 1 so sclk msb shift in shift out note: cpol indicates clock polarity of serial master, cpol=1 for sclk high while idle, cpol=0 for sclk low while not transmitting. cpha indicates clock phase. the combination of cpol bit and cpha bit decides which serial mode is supported. p/n: pm1638 mx25v4006e rev. 1.4, nov. 14, 2013 9 data protection during power transition, there may be some false system level signals which result in inadvertent erasure or programming. the device is designed to protect itself from these accidental write cycles. the state machine will be reset as standby mode automatically during power up. in addition, the control register architecture of the device constrains that the memory contents can only be changed after specifc command sequences have completed successfully. in the following, there are several features to protect the system from the accidental write cycles during vcc power- up and power-down or from system noise. ? valid command length checking: the command length will be checked whether it is at byte base and completed on byte boundary. ? write enable (wren) command: wren command is required to set the write enable latch bit (wel) before other command to change data. the wel bit will return to reset stage under following situation: - power-up - w rite disable (wrdi) command completion - w rite status register (wrsr) command completion - page program (pp) command completion - sector erase (se) command completion - block erase (be) command completion - chip erase (ce) comma nd completion ? deep power down mode: by entering deep power down mode, the fash device also is under protected from writing all commands except release from deep power down mode command (rdp) and read electronic sig - nature command (res). i. block lock protection - software protection mode (spm): by using bp0-bp2 bits to set the part of flash protected from data change. - hardware protection mode (hpm): by using wp# going low to protect the bp0-bp2 bits and srwd bit from data change. table 2. protected area sizes status bit protect level 4mb bp2 bp1 bp0 0 0 0 0 (none) none 0 0 1 1 (1 block) block 7 0 1 0 2 (2 blocks) block 6-7 0 1 1 3 (4

serial communications with the device. the hold feature will not stop the operation of write status register, programming, or erasing in progress. the operation of hold requires chip select(cs#) keeping low and starts on falling edge of hold# pin signal while serial clock (sclk) signal is being low (if serial clock signal is not being low, hold operation will not start until serial clock signal being low). the hold condition ends on the rising edge of hold# pin signal while se - rial clock(sclk) signal is being low (if serial clock signal is not being low, hold operation will not end until serial clock being low), see figure 2. hold# sclk hold condition (standard use) hold condition (non-standard use) the serial data output (so) is high impedance, both serial data input (si) and serial clock (sclk) are don't care during the hold operation. if chip select (cs#) drives high during hold operation, it will reset the internal logic of the device. to re-start communication with chip, the hold# must be at high and cs# must be at low. figure 2. hold condition operation p/n: pm1638 mx25v4006e rev. 1.4, nov. 14, 2013 11 table 3. command definition command (byte) wren (write

(2) write disable (wrdi) the write disable (wrdi) instruction is for resetting write enable latch (wel) bit. the sequence is shown as figure 12 . the wel bit is reset by following situations: - power-up - w rite disable (wrdi) instruction completion - w rite status register (wrsr) instruction completion - page program (pp) instruction completion - sector erase (se) instruction completion - block erase (be) instruction completion - chip erase (ce) instruction completion p/n: pm1638 mx25v4006e rev. 1.4, nov. 14, 2013 13 (3) read status register (rdsr) the rdsr instruction is for reading status register bits. the read status register can be read at any time (even in program/erase/write status register condition) and continuously. it is recommended to check the write in progress (wip) bit before sending a new instruction when a program, erase, or write status register operation is in progress. the sequence is shown as figure 13 . the defnition of the status register bits is as below: wip bit. the write in progress (wip) bit, a volatile bit, indicates whether the device is busy in program/erase/write status register progress. when wip bit sets to 1, which means the device is busy in program/erase/write status register progress. when wip bit sets to 0, which means the device is not in progress of program/erase/write status register cycle. wel bit. the write enable latch (wel) bit, a volatile bit, indicates whether the device is set to internal write enable latch. when wel bit sets to 1, which means the internal write enable latch is set, the device can accept program/ erase/write status register instruction. when wel bit sets to 0, which means no internal write enable latch; the de - vice will not accept program/erase/write status register instruction. bp2, bp1, bp0 bits. the block protect (bp2, bp1, bp0) bits, non-volatile bits, indicate the protected area(as de - fned in table 2 ) of the device to against the program/erase instruction without hardware protection mode being set. to write the block protect (bp2, bp1, bp0) bits requires the write status register (wrsr) instruction to be executed. those bits defne the protected area of the memory to against page program (pp), sector erase (se), block erase (be) and chip erase(ce) instructions (only if all block protect bits set to 0, the ce instruction can be executed) srwd bit. the status register write disable (srwd) bit, non-volatile bit, is operated together with write protec - tion (wp#) pin for providing hardware protection mode. the hardware protection mode requires srwd sets to 1 and wp# pin signal is low stage. in the hardware protection mode, the write status register (wrsr) instruction is no longer accepted for execution and the srwd bit and block protect bits (bp2, bp1, bp0) are read only. bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 srwd status register write protect na na bp2 (the level of protected block) bp1 (the level of protected block) bp0 (the level of protected block) wel (write enable latch) wip (write in progress bit) 1= status register write disable na na (note 1) (note 1) (note 1) 1=write enable 0=not write enable 1=write operation 0=not in write operation note: 1. see the table " protected area sizes". 2. the endurance cycles of protect bits are 100,000 cycles; however, the tw time out spec of protect bits is relaxed as tw = n x 15ms (n is a multiple of 10,000 cycles, ex. n = 2 for 20,000 cycles) after 10,000 cycles on those bits. p/n: pm1638 mx25v4006e rev. 1.4, nov. 14, 2013 14 (4) write status register (wrsr) the wrsr instruction is for changing the values of status register bits. before sending wrsr instruction, the write enable (wren) instruction must be decoded and executed to set the write enable latch (wel) bit in ad - vance. the wrsr instruction can change the value of block protect (bp2, bp1, bp0) bits to defne the protected area of memory (as shown in table 2 ). the wrsr also can set or reset the status register write disable (srwd) bit in accordance with write protection (wp#) pin signal. the wrsr instruction cannot be executed once the hard - ware protected mode (hpm) is entered. the sequence is shown as figure 14. the wrsr instruction has no effect on b6, b5, b1, b0 of the status register. the cs# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed. the self-timed write status register cycle time (tw) is initiated as soon as chip select (cs#) goes high. the write in progress (wip) bit still can be check out during the write status register cycle is in progress. the wip sets 1 during the tw timing, and sets 0 when write status register cycle is completed, and the write enable latch (wel) bit is reset. table 4. protection modes note: 1. as defned by the values in the block protect (bp2, bp1, bp0) bits of the status register, as shown in table 2 . as the above table showing, the summary of the software protected mode (spm) and hardware protected mode (hpm). software protected mode (spm): - when sr wd bit=0, no matter wp# is low or high, the wren instruction may set the wel bit and can change the values of srwd, bp2, bp1, bp0. the protected area, which is defned by bp2, bp1, bp0, is at software protected mode (spm). - when sr wd bit=1 and wp# is high, the wren instruction may set the wel bit can change the values of srwd, bp2, bp1, bp0. the protected area, which is defned by bp2, bp1, bp0, is at software protected mode (spm). note: if srwd bit=1 but wp# is low, it is impossible to write the status register even if the wel bit has previously been set. it is rejected to write the status register and not be executed. hardware protected mode (hpm): - when sr wd bit=1, and then wp# is low (or wp# is low before srwd bit=1), it enters the hardware protected mode (hpm). the data of the protected area is protected by software protected mode by bp2, bp1, bp0 and hardware protected mode by the wp# to against data modifcation. note: to exit the hardware protected mode requires wp# driving high once the hardware protected mode is entered. if the wp# pin is permanently connected to high, the hardware protected mode can never be entered; only can use software protected mode via bp2, bp1, bp0. mode status register condition wp# and srwd bit status memory software protection mode (spm) status register can be written in (wel bit is set to "1") and the srwd, bp2-bp0 bits can be changed wp#=1 and srwd bit=0, or wp#=0 and srwd bit=0, or wp#=1 and srwd=1 the protected area cannot be program or erase. hardware protection mode (hpm) the srwd, bp2-bp0 of status register bits cannot be changed wp#=0, srwd bit=1 the protected area cannot be program or erase. p/n: pm1638 mx25v4006e rev. 1.4, nov. 14, 2013 15 (5) read data bytes (read) the read instruction is for reading data out. the address is latched on rising edge of sclk, and data shifts out on the falling edge of sclk at a maximum frequency fr. the frst address byte can be at any location. the address is automatically increased to the next higher address after each byte data is shifted out, so the whole memory can be read out at a single read instruction. the address counter rolls over to 0 when the highest address has been reached. the sequence is shown as figure 15. (6) read data bytes at higher speed (fast_read) the fast_read instruction is for quickly reading data out. the address is latched on rising edge of sclk, and data of each bit shifts out on the falling edge of sclk at a maximum frequency fc. the frst address byte can be at any location. the address is automatically increased to the next higher address after each byte data is shifted out, so the whole memory can be read out at a single fast_read instruction. the address counter rolls over to 0 when the highest address has been reached. the sequence is shown as figure 16. while program/erase/write status register cycle is in progress, fast_read instruction is rejected without any im - pact on the program/erase/write status register current cycle. (7) dual output mode (dread) the dread instruction enable double throughput of serial flash in read mode. the address is latched on rising edge of sclk, and data of every two bits(interleave on 1i/2o pins) shift out on the falling edge of sclk at a maxi - mum frequency ft. the frst address byte can be at any location. the address is automatically increased to the next higher address after each byte data is shifted out, so the whole memory can be read out at a single dread instruc - tion. the address counter rolls over to 0 when the highest address has been reached. once writing dread instruc - tion, the following address/dummy/data out will perform as 2-bit instead of previous 1-bit. the sequence is shown as figure 17 . while program/erase/write status register cycle is in progress, dread instruction is rejected without any impact on the program/erase/write status register current cycle. the dread only perform read operation. program/erase /read id/read status....operation do not support dread throughputs. (8) sector erase (se) the sector erase (se) instruction is for erasing the data of the chosen sector to be "1". a write enable (wren) in - struction must execute to set the write enable latch (wel) bit before sending the sector erase (se). any address of the sector (see table 1 ) is a valid address for sector erase (se) instruction. the cs# must go high exactly at the byte boundary (the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not executed. address bits [am-a12] (am is the most signifcant address) select the sector address. p/n: pm1638 mx25v4006e rev. 1.4, nov. 14, 2013 16 the sequence is shown as figure 18. the self-timed sector erase cycle time (tse) is initiated as soon as chip select (cs#) goes high. the write in progress (wip) bit still can be check out during the sector erase cycle is in progress. the wip sets 1 during the tse timing, and sets 0 when sector erase cycle is completed, and the write enable latch (wel) bit is reset. if the page is protected by bp2, bp1, bp0 bits, the sector erase (se) instruction will not be executed on the page. (9) block erase (be) the block erase (be) instruction is for erasing the data of the chosen block to be "1". a write enable (wren) in - struction must execute to set the write enable latch (wel) bit before sending the block erase (be). any address of the block (see table 1 ) is a valid address for block erase (be) instruction. the cs# must go high exactly at the byte boundary (the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not executed. the sequence is shown as figure 19. the self-timed block erase cycle time (tbe) is initiated as soon as chip select (cs#) goes high. the write in progress (wip) bit still can be check out during the sector erase cycle is in progress. the wip sets 1 during the tbe timing, and sets 0 when sector erase cycle is completed, and the write enable latch (wel) bit is reset. if the page is protected by bp2, bp1, bp0 bits, the block erase (be) instruction will not be executed on the page. (10) chip erase (ce) the chip erase (ce) instruction is for erasing the data of the whole chip to be "1". a write enable (wren) instruc - tion must execute to set the write enable latch (wel) bit before sending the chip erase (ce). any address of the sector (see table 1 ) is a valid address for chip erase (ce) instruction. the cs# must go high exactly at the byte boundary( the latest eighth of address byte been latched-in); otherwise, the instruction will be rejected and not ex - ecuted. the sequence is shown as figure 20 . the self-timed chip erase cycle time (tce) is initiated as soon as chip select (cs#) goes high. the write in progress (wip) bit still can be check out during the chip erase cycle is in progress. the wip sets 1 during the tce timing, and sets 0 when chip erase cycle is completed, and the write enable latch (wel) bit is reset. if the chip is protected by bp2, bp1, bp0 bits, the chip erase (ce) instruction will not be executed. it will be only executed when bp2, bp1, bp0 all set to "0". (11) page program (pp) the page program (pp) instruction is for programming the memory to be "0". a write enable (wren) instruc - tion must execute to set the write enable latch (wel) bit before sending the page program (pp). the device programs only the last 256 data bytes sent to the device. the last address byte (the 8 least signifcant address bits, a7-a0) should be set to 0 for 256 bytes page program. if a7-a0 are not all zero, transmitted data that exceed page length are programmed from the starting address (24-bit address that last 8 bit are all 0) of currently selected page. if the data bytes sent to the device exceeds 256, the last 256 data byte is programmed at the request page and previous data will be disregarded. if the data bytes sent to the device has not exceeded 256, the data will be programmed at the request address of the page. there will be no effort on the other data bytes of the same page. p/n: pm1638 mx25v4006e rev. 1.4, nov. 14, 2013 17 (12) deep power-down (dp) the deep power-down (dp) instruction is for setting the device on the minimizing the power consumption (to enter - ing the deep power-down mode), the standby current is reduced from isb1 to isb2). the deep power-down mode requires the deep power-down (dp) instruction to enter, during the deep power-down mode, the device is not ac - tive and all write/program/erase instruction are ignored. when cs# goes high, it's only in standby mode not deep power-down mode. it's different from standby mode. the sequence is shown as figure 22 . once the dp instruction is set, all instruction will be ignored except the release from deep power-down mode (rdp) and read electronic signature (res) instruction. (res instruction to allow the id been read out). when power- down, the deep power-down mode automatically stops, and when power-up, the device automatically is in standby mode. for rdp instruction the cs# must go high exactly at the byte boundary (the latest eighth bit of instruction code been latched-in); otherwise, the instruction will not executed. as soon as chip select (cs#) goes high, a delay of tdp is required before entering the deep power-down mode and reducing the current to isb2. (13) release from deep power-down (rdp), read electronic signature (res) the release from deep power-down (rdp) instruction is terminated by driving chip select (cs#) high. when chip select (cs#) is driven high, the device is put in the stand-by power mode. if the device was not previously in the deep power-down mode, the transition to the stand-by power mode is immediate. if the device was previously in the deep power-down mode, though, the transition to the stand-by power mode is delayed by tres2, and chip select (cs#) must remain high for at least tres2(max), as specifed in table 7 . once in the stand-by power mode, the device waits to be selected, so that it can receive, decode and execute instructions. res instruction is for reading out the old style of 8-bit electronic signature, whose values are shown as table of id defnitions . this is not the same as rdid instruction. it is not recommended to use for new design. for new deisng, please use rdid instruction. even in deep power-down mode, the rdp and res are also allowed to be executed, only except the device is in progress of program/erase/write cycle; there's no effect on the current program/erase/ write cycle in progress. the sequence is shown as figure 23 and figure 24 . the res instruction is ended by cs# goes high after the id been read out at least once. the id outputs repeat - edly if continuously send the additional clock cycles on sclk while cs# is at low. if the device was not previously in deep power-down mode, the device transition to standby mode is immediate. if the device was previously in deep power-down mode, there's a delay of tres2 to transit to standby mode, and cs# must remain to high at least tres2(max). once in the standby mode, the device waits to be selected, so it can be receive, decode, and execute instruction. the sequence is shown as figure 21 . the cs# must be kept to low during the whole page program cycle; the cs# must go high exactly at the byte boundary( the latest eighth bit of data being latched in), otherwise the instruction will be rejected and will not be ex - ecuted. the self-timed page program cycle time (tpp) is initiated as soon as chip select (cs#) goes high. the write in progress (wip) bit still can be check out during the page program cycle is in progress. the wip sets 1 during the tpp timing, and sets 0 when page program cycle is completed, and the write enable latch (wel) bit is reset. if the page is protected by bp2, bp1, bp0 bits, the page program (pp) instruction will not be executed. p/n: pm1638 mx25v4006e rev. 1.4, nov. 14, 2013 18 the rdp instruction is for releasing from deep power down mode. (14) read identifcation (rdid) the rdid instruction is for reading the manufacturer id of 1-byte and followed by device id of 2-byte. the macronix manufacturer id is c2(hex), the memory type id is 20(hex) as the frst-byte device id, and the individual device id of second-byte id is as followings: 13(hex) for mx25v4006e. the sequence is shown as )ljxuh . while program/erase operation is in progress, it will not decode the rdid instruction, so there's no effect on the cy - cle of program/erase operation which is currently in progress. when cs# goes high, the device is at standby stage. (15) read electronic manufacturer id & device id (rems) the rems instruction is an alternative to the release from power-down/device id instruction that provides both the jedec assigned manufacturer id and the specifc device id. the rems instruction is very similar to the release from power-down/device id instruction. the instruction is initi - ated by driving the cs# pin low and shift the instruction code "90h" followed by two dummy bytes and one bytes ad - dress (a7~a0). after which, the manufacturer id for macronix (c2h) and the device id are shifted out on the falling edge of sclk with most signifcant bit (msb) frst as shown in figure 26 . the device id values are listed in 7deoh . id defnitions. if the one-byte address is initially set to 01h, then the device id will be read frst and then followed by the manufacturer id. the manufacturer and device ids can be read continuously, alternating from one to the other. the instruction is completed by driving cs# high. table 5.
