13 mx25l5121e MX25L1021E p/n: pm1573 rev. 0.01, apr. 07, 2010 (4) 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 condition) and continuously. it is recommended to check the write in progress (wip) bit before sending a new instruction when a program or erase operation is in progress. the sequence of issuing rdsr instruction is: cs# goes lowsending rdsr instruction codestatus register data out on so (please refer to figure 12- 1, figure 12- 2) 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 progress. when wip bit sets to 1, which means the device is busy in program/erase progress. when wip bit sets to 0, which means the device is not in progress of program/erase 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 instruction. when wel bit sets to 0, which means no internal write enable latch; the device will not accept program/erase instruction. bp1, bp0 bits. the block protect (bp1, bp0) bits, volatile bits, indicate the protected area(as defned in table 1) of the device to against the program/erase instruction without hardware protection mode being set. to write the block protect (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, volatile bit, is operated together with write protection (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 ac - cepted for execution and the srwd bit and block protect bits (bp1, bp0) are read only. table 5. status register note: 1. see the table "protected area sizes". the default bp0-bp2 values are "1" (protected). 2. the srwd default value is "0" bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 srwd (status register write protect) reserved reserved reserved bp1 (level of protected block) bp0 (level of protected block) wel (write enable latch) wip (write in progress bit) 1=status register write disable 0 0 0 (note 1) (note 1) 1=write enable 0=not write enable 1=write operation 0=not in write operation free datasheet http://
14 mx25l5121e MX25L1021E p/n: pm1573 rev. 0.01, apr. 07, 2010 (5) 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 (bp1, bp0) bits to defne the protected area of memory (as shown in table 1). 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 hardware protected mode (hpm) is entered. the sequence of issuing wrsr instruction is: cs# goes low sending wrsr instruction code status register data on si cs# goes high. (see figure 13) the wrsr instruction has no effect on b6, b5, b4, 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 6. protection modes note: 1. as defned by the values in the block protect (bp1, bp0) bits of the status register, as shown in table 1. as the table above showing, the summary of the software protected mode (spm) and hardware protected mode (hpm). software protected mode (spm): - when srwd bit=0, no matter wp# is low or high, the wren instruction may set the wel bit and can change the values of srwd, bp1, bp0. the protected area, which is defned by bp1, bp0, is at software protected mode (spm). - when srwd bit=1 and wp# is high, the wren instruction may set the wel bit can change the values of srwd, bp1, bp0. the protected area, which is defned by 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 previ - ously been set. it is rejected to write the status register and not be executed. hardware protected mode (hpm): - when srwd 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 bp1, bp0 and hard - ware 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 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, bp0-bp1 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, bp0-bp1 of status register bits cannot be changed wp#=0, srwd bit=1 the protected area cannot be program or erase. free datasheet http://
15 mx25l5121e MX25L1021E p/n: pm1573 rev. 0.01, apr. 07, 2010 (6) 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 fc. the frst address 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. this product does not provide the function of read around. after reading through density 512kb or 1mb, cs# must go high. otherwise, the data correctness will not be guaranteed. if the device needs to read data again, it must issue read command once more. the sequence of issuing read instruction is: cs# goes low sending read instruction code 3-bytes address on sidata out on soto end read operation can use cs# to high at any time during data out. (please refer to figure 14) (7) 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 of issuing fast_read instruction is: cs# goes low sending fast_read instruction code 3-byte address on si 1-dummy byte address on sidata out on so to end fast_read operation can use cs# to high at any time during data out. (please refer to figure 15) 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. (8) sector erase (se) the sector erase (se) instruction is for erasing the data of the chosen sector to be "1". the instruction is used for any 4k-bytes sector. a write enable (wren) instruction must execute to set the write enable latch (wel) bit be - fore sending the sector erase (se). any address of the sector (please refer to table 1) is a valid address for sector erase (se) instruction. the cs# must go high exactly at the byte boundary (the eighth bit of last 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. the sequence of issuing se instruction is: cs# goes lowsending se instruction code3-bytes address on si cs# goes high. (please refer to figure 16) 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. (9) block erase (be) the block erase (be) instruction is for erasing the data of the chosen block to be "1". the instruction is used for 64k-byte sector erase operation. a write enable (wren) instruction must execute to set the write enable latch (wel) free datasheet http://

(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 18. 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. (11) 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). after the instruction and address input, data to be programmed is input sequentially. the internal sequence controller will sequentially program the data from the initial address. if the transmitted data goes beyond the page boundary, the internal se - quence controller may not function properly and the content of the device will not be guaranteed. therefore, if the initial a4-a0 (the fve least signifcant address bits) are set to all 0, maximum 32 bytes of data can be input sequen - tially. if the initial address a4-a0 (the fve least signifcant address bits) are not set to all 0, maximum bytes of data input will be the subtraction of the initial address a4-a0 from 32bytes. the data exceeding 32bytes data is not sent to device. in this case, data is not guaranteed. the sequence of issuing pp instruction is: cs# goes low sending pp instruction code 3-bytes address on si at least 1-byte on data on si cs# goes high. (please refer to figure 19) the cs# must be kept to low during the whole page program cycle; the cs# must go high exactly at the byte boundary( the 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 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. (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 - free datasheet http://
17 mx25l5121e MX25L1021E p/n: pm1573 rev. 0.01, apr. 07, 2010 tive and all read/write/program/erase instruction are ignored. the sequence of issuing dp instruction is: cs# goes lowsending dp instruction code cs# goes high. (please refer to figure 20) once the dp instruction is set, all instruction will be ignored except the release from deep power down mode (rdp) instruction. 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. (13) release from deep power-down (rdp) 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 mode. if the device was not previously in the deep power down mode, the transition to the standby mode is immediate. if the device was previously in the deep power down mode, though, the transition to the standby mode is delayed by tres1, and chip select (cs#) must remain high for at least tres1(max), as specifed in table 8 . ac characteristics. once in the standby mode, the device waits to be selected, so that it can receive, decode and execute instructions. the rdp instruction is only for releasing from deep power down mode. the sequence is shown as figure 2 1 . even in deep power down mode, the rdp is also allowed to be executed, only except the device is in progress of program/erase cycle; there's no effect on the current program/erase cycle in progress. free datasheet http://
