6 2. general description mx25l3273e is 32mb bits serial flash memory, which is confgured as 4,194,304 x 8 internally. when it is in two or four i/o mode, the structure becomes 16,777,216 bits x 2 or 8,388,608 bits x 4. mx25l3273e feature a se - rial peripheral interface and software protocol allowing operation on a simple 3-wire bus while it is in single i/o mode. the three bus signals are a clock input (sclk), a serial data input (si), and a serial data output (so). se- rial access to the device is enabled by cs# input. mx25l3273e, mxsmio ? (serial multi i/o) fash memory, provides sequential read operation on whole chip and multi-i/o features. when it is in dual i/o mode, the si pin and so pin become sio0 pin and sio1 pin for address/dummy bits input and data output. when it is in quad i/o mode, the si pin, so pin become sio0 pin and sio1 pin, sio2 pin and sio3 pin for address/dummy bits input and data input/output. after program/erase command is issued, auto program/erase algorithms which program/erase and verify the specifed page or sector/block locations will be executed. program command is executed on byte basis, or page (256 bytes) basis, or word basis for continuous program mode, and erase command is executed on sector (4k-byte), block (32k-byte/64k-byte), 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 mx25l3273e utilizes macronix's proprietary memory cell, which reliably stores memory contents even after 100,000 program and erase cycles. table 1. read performance numbers of dummy cycles 4 i/o 6 86* 8 104 note: *means default status mx25l3273e p/n: pm1906 rev. 1.1, nov. 07, 2013

9 6. 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 complet - ed 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 , 4pp) command completion - continuous program mo de (cp) instruction completion - sector erase (se) command completion - block erase (be, be32k) command completion - chip erase (ce) comma nd completion - single block lock/unlock (sblk/sbulk) instruction completion - gang block lock/unlock (gblk/gbulk) instruction 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 signature command (res). i. block lock protection - the software protected mode (spm) uses (bp3, bp2, bp1, bp0) bits to allow part of memory to be pro - tected as read only. the protected area defnition is shown as table of "table 2. protected area sizes" , the protected areas are more fexible which may protect various areas by setting value of bp0-bp3 bits. - mx25l327 3e provides individual block (or sector) write protect & unprotect. user may enter the mode with wpsel command and conduct individual block (or sector) write protect with sblk instruction, or sbulk for individual block (or sector) unprotect. under the mode, user may conduct whole chip (all blocks) protect with gblk instruction and unlock the whole chip with gbulk instruction. mx25l3273e p/n: pm1906 rev. 1.1, nov. 07, 2013

13 8. device operation 1. before a command is issued, status register should be checked to ensure device is 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. 3. when correct command is inputted to this lsi, this lsi becomes active mode and keeps the active mode until next cs# rising edge. 4. for standard single data rate serial mode, 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 mode 0 and mode 3 is shown as "figure 1. serial modes supported (for normal serial mode)" . 5. for the following instructions: rdid, rdsr, rdscur, read, fast_read, rdsfdp, 2read, dread, 4read, qread, rdblock, res, rems, rems2, and rems4 the shifted-in instruction sequence is fol - lowed by a data-out sequence. after any bit of data being shifted out, the cs# can be high. for the follow - ing instructions: wren, wrdi, wrsr, se, be, be32k, hpm, ce, pp, cp, 4pp, rdp, dp, wpsel, sblk, sbulk, gblk, gbulk, enso, exso, wrscur, esry and dsry. the cs# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed. 6. during the progress of write status register, program, erase operation, to access the memory array is ne - glected and not affect the current operation of write status register, program, erase. 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. figure 1. serial modes supported (for normal serial mode) sclk msb cpha shift in shift out si 0 1 cpol 0 (serial mode 0) (serial mode 3) 1 so sclk msb mx25l3273e p/n: pm1906 rev. 1.1, nov. 07, 2013

39 9-18. page program (pp) the page program (pp) instruction is for programming the memory to be "0". a write enable (wren) instruction 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. the sequence of issuing pp instruction is: cs# goes low sending pp instruction code 3-byte address on si at least 1-byte on data on si cs# goes high. 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 executed. 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 checked 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 bp3~0 (wpsel=0) or by individual lock (wpsel=1), the array data will be protected (no change) and the wel bit will still be reset. the sio[3:1] are don't care when during this mode. figure 20. page program (pp) sequence (command 02) 4241 43 44 45 46 47 48 49 50 52 53 54 55 40 23 21 345678 9 10 28 29 30 31 32 33 34 35 22 21 3210 36 37 38 24-bit address 0 76543 2 0 1 data byte 1 39 51 76543 2 0 1 data byte 2 76543 2 0 1 data byte 3 data byte 256 2079 2078 2077 2076 2075 2074 2073 76543 2 0 1 2072 msb msb msb msb msb sclk cs# si sclk cs# si 02h command mx25l3273e p/n: pm1906 rev. 1.1, nov. 07, 2013
40 9-19. 4 x i/o page program (4pp) the quad page program (4pp) instruction is for programming the memory to be "0". a write enable (wren) instruction must execute to set the write enable latch (wel) bit. the quad page programming takes four pins: sio0, sio1, sio2, and sio3, which can raise programmer performance and the effectiveness of application of lower clock less than 104mhz. for system with faster clock, the quad page program cannot provide more actual favors, because the required internal page program time is far more than the time data fows in. therefore, we suggest that while executing this command (especially during sending data), user can slow the clock speed down to 104mhz below. the other function descriptions are as same as standard page program. the sequence of issuing 4pp instruction is: cs# goes low sending 4pp instruction code 3-byte address on sio[3:0] at least 1-byte on data on sio[3:0] cs# goes high. if the page is protected by bp3~0 (wpsel=0) or by individual lock (wpsel=1), the array data will be protected (no change) and the wel bit will still be reset. figure 21. 4 x i/o page program (4pp) sequence (command 38) a20 a16 a12 a8 a4 a0 a21 a17 a13 a9 a5 a1 a22 a18 a14 a10 a6 a2 a23 a19 a15 a11 a7 a3 21 3456789 6 add cycles data byte 1 data byte 2 data byte 256 0 sclk cs# si/sio0 so/sio1 sio3 sio2 38 command 10 11 12 13 14 15 16 17 524 525 d4 d0 d5 d1 d6 d2 d7 d3 d4 d0 d5 d1 d6 d2 d7 d3 d4 d0 d5 d1 d6 d2 d7 d3 mx25l3273e p/n: pm1906 rev. 1.1, nov. 07, 2013

43 9-20. continuous program mode (cp mode) the cp mode may enhance program performance by automatically increasing address to the next higher ad - dress after each byte data has been programmed. the continuous program (cp) instruction is for multiple bytes program to flash. a write enable (wren) in - struction must execute to set the write enable latch (wel) bit before sending the continuous program (cp) instruction. cs# requires to go high before cp instruction is executing. after cp instruction and address input, two bytes of data is input sequentially from msb(bit7) to lsb(bit0). the frst byte data will be programmed to the initial address range with a0=0 and second byte data with a0=1. if only one byte data is input, the cp mode will not process. if more than two bytes data are input, the additional data will be ignored and only two byte data are valid. any byte to be programmed should be in the erase state (ff) frst. it will not roll over during the cp mode, once the last unprotected address has been reached, the chip will exit cp mode and reset write enable latch bit (wel) as "0" and cp mode bit as "0". please check the wip bit status if it is not in write progress before enter - ing next valid instruction. during cp mode, the valid commands are cp command (ad hex), wrdi command (04 hex), rdsr command (05 hex), and rdscur command (2b hex). and the wrdi command is valid after com - pletion of a cp programming cycle, which means the wip bit=0. the sequence of issuing cp instruction is : cs# goes low sending cp instruction code 3-byte address on si pin two data bytes on si cs# goes high to low sending cp instruction and then continue two data bytes are programmed cs# goes high to low till last desired two data bytes are programmed cs# goes high to low sending wrdi (write disable) instruction to end cp mode send rdsr instruction to verify if cp mode word program ends, or send rdscur to check bit4 to verify if cp mode ends. three methods to detect the completion of a program cycle during cp mode: 1) software method-i: by checking wip bit of status register to detect the completion of cp mode. 2) software method-ii: by waiting for a tbp time out to determine if it may load next valid command or not. 3) hardware method: by writing esry (enable so to output ry/by#) instruction to detect the completion of a program cycle during cp mode. the esry instruction must be executed before cp mode execution. once it is enable in cp mode, the cs# goes low will drive out the ry/by# status on so, "0" indicates busy stage, "1" indicates ready stage, so pin outputs tri-state if cs# goes high. dsry (disable so to output ry/by#) instruction to disable the so to output ry/by# and return to status register data output during cp mode. please note that the esry/dsry commands are not accepted unless the completion of cp mode. if the page is protected by bp3~0 (wpsel=0) or by individual lock (wpsel=1), the array data will be pro - tected (no change) and the wel bit will still be reset. mx25l3273e p/n: pm1906 rev. 1.1, nov. 07, 2013
44 notes: (1) during cp mode, the valid commands are cp command (ad hex), wrdi command (04 hex), rdsr command (05 hex), rdscur command (2b hex), rsten command (66 hex) and rst command (99hex). (2) once an internal programming operation begins, cs# goes low will drive the status on the so pin and cs# goes high will return the so pin to tri-state. (3) t o end the cp mode, either reaching the highest unprotected address or sending write disable (wrdi) command (04 hex) may achieve it and then it is recommended to send rdsr command (05 hex) to verify if cp mode is ended. please be noticed that software reset and hardware reset can end the cp mode. cs# sclk 0 1 6 7 8 9 si command ad (hex) 30 31 31 s0 high impedance 32 47 48 status (2) data in 24-bit address byte 0, byte1 0 1 valid command (1) data in byte n-1, byte n 6 7 8 20 21 22 23 0 04 (hex) 24 7 0 7 05 (hex) 8 figure 24. continously program (cp) mode sequence with hardware detection (command ad) mx25l3273e p/n: pm1906 rev. 1.1, nov. 07, 2013
45 9-21. deep power-down (dp) the deep power-down (dp) instruction is for setting the device on the minimizing the power consumption (to en - tering 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 active and all write/program/erase instructions 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 of issuing dp instruction is: cs# goes low sending dp instruction code cs# goes high. the sio[3:1] are don't care when during this mode. once the dp instruction is set, all instructions will be ignored except the release from deep power-down mode (rdp) and read electronic signature (res) instruction. (those instructions allow the id being reading 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 has been latched-in); otherwise, the instruction will not be 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. figure 25. deep power-down (dp) sequence (command b9) 21 34567 0 t dp deep power-down mode stand-by mode sclk cs# si b9h command mx25l3273e p/n: pm1906 rev. 1.1, nov. 07, 2013
46 9-22. 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 standby power mode. if the device was not previously in the deep power-down mode, the transition to the standby power mode is immediate. if the device was previously in the deep power-down mode, though, the transition to the standby power mode is delayed by tres2, and chip select (cs#) must remain high for at least tres2(max), as specifed in "table 13. ac characteristics" . once in the standby 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 7. id defnitions" . this is not the same as rdid instruction. it is not recommended to use for new design. for new design, 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 cycles; there's no effect on the current program/erase/write cycles in progress. the sio[3:1] are don't care when during this mode. 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 previous - ly 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 receive, decode, and execute instruction. the rdp instruction is for releasing from deep power-down mode. figure 26. release from deep power-down and read electronic signature (res) sequence (command ab) 23 21 345678 9 10 28 29 30 31 32 33 34 35 22 21 3210 36 37 38 76543 2 0 1 high-z electronic signature out 3 dummy bytes 0 msb stand-by mode deep power-down mode msb t res2 sclk cs# si so abh command mx25l3273e p/n: pm1906 rev. 1.1, nov. 07, 2013
