erasure or pro- gramming. 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 ar - chitecture of the device constrains that the memory contents can only be changed after specifc command sequenc - es have completed successfully. in the following, there are several features to protect the system from the accidental write cycles during vcc pow - erup and power-down or from system noise. ? v alid command length checking: the command length will be checked whether it is at byte base and completed on byte boundary. ? w rite enable (wren) command: wren command is required to set the write enable latch bit (wel) before is - suing other commands to change data. the wel bit will return to resetting stage while the following conditions occurred: - power-up - completion of w rite disable (wrdi) command - completion of w rite status register (wrsr) command - completion of page program (pp) command - completion of quad page program (4pp) command - completion of sector erase (se) command - completion of block erase 32kb (be32k) command - completion of block erase (be) command - completion of chip erase (ce) command - completion of w rite protection select (wpsel) command - completion of w rite security register (wrscur) command - completion of single block lock/unlock (sblk/sbulk) command - completion of gang block lock/unlock (gblk/gbulk) command ? deep power down mode: by entering deep power down mode, the fas h device also is under protected from writ- ing all commands except release from deep power down mode command (rdp) and read electronic signature command (res). ? advanced security features: there are some protection and security features which protect content from inad - vertent write and hostile access. i. block lock protection - the software protected mode (spm) use (bp2, bp1, bp0) bits to allow part of memory to be protected 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 area by setting value of bp0-bp2 bits. please refer to table of "table 2. protected area sizes" . - the hardware protected mode (hpm) use wp#/sio2 to protect the (bp2, bp1, bp0) bits and srwd bit. if the system goes into four i/o read mode, the feature of hpm will be disabled. mx25u2033e p/n: pm1743 rev. 1.3, nov. 14, 2013 11 11 table 2. protected area sizes table 3. 4k-bit secured otp defnition ii. additional 4k-bit

nov. 14, 2013 13 13 7. 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 device, it enters standby mode and remains in standby mode until next cs# falling edge. in standby mode, so pin of the device is high-z. 3. when correct command is inputted to this device, it enters active mode and remains in active mode until next cs# rising edge. 4. input data is latched on the rising edge of serial clock (sclk) and data is shifted out on the falling edge of sclk. the difference of serial mode 0 and mode 3 is shown as "figure 1. serial modes supported" . 5. for the following instructions: rdid, rdsr, rdscur, read, fast_read, rdsfdp, 2read, 4read, res, rems, rems2, and rems4, the shifted-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, be32k, be, ce, pp, 4pp, rdp, dp, wpsel, sblk, sbulk, gblk, gbulk,enso, exso, and wrscur, the cs# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed. 6. while a w rite status register, program or erase operation is in progress, access to the memory array is ne - glected and will not affect the current operation of wrscur, wpsel write status register, program and erase. figure 1. serial modes supported 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. sclk msb cpha shift in shift out si 0 1 cpol 0 (serial mode 0) (serial mode 3) 1 so sclk msb mx25u2033e p/n: pm1743 rev. 1.3, nov. 14, 2013 14 14 8. hold feature hold# pin signal goes low to hold any 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 se- rial clock signal being low). the hold condition ends on the rising 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 end until serial clock being low), see "figure 2. hold condition operation" . figure 2. hold condition operation hold# cs# sclk hold condition (standard) hold condition (non-standard) 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. mx25u2033e p/n: pm1743 rev. 1.3, nov. 14, 2013 15 15 9. command description table 5. command set command (byte) wren (write enable) wrdi (write disable) rdsr (read status

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. 9-18. release from deep power-down (rdp), read electronic signature (res) the release from deep power-down (rdp) instruction is completed 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 se - lect (cs#) must remain high for at least tres2 (max), as specifed in "table 14. ac characteristics" . ac character - istics. once in the stand-by power 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. res instruction is for reading out the old style of 8-bit electronic signature, whose values are shown as table of id defnitions on next page. this is not the same as rdid instruction. it is not recommended to use for new design. for new design, please use rdid instruction. the sequence is shown as )ljxuh5'3dqg5hdg(ohfwurqlf6ljqdwxuh5(66htxhqfh&rppdqg and )ljxuh5hohdhiurp'hhs3rzhugrzq5'36htxhqfh&rppdqg . 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 cy - cle; there's no effect on the current program/erase/write cycle in progress. 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. 9-19. read electronic manufacturer id & device id (rems), (rems2), (rems4) the rems, rems2 and rems4 instruction provides both the jedec assigned manufacturer id and the specifc device id. the instruction is initiated by driving the cs# pin low and shift the instruction code "90h", "dfh" or "efh" followed by two dummy bytes and one bytes address (a7~a0). after which, the manufacturer id for mxic (c2h) and the de - vice id are shifted out on the falling edge of sclk with most signifcant bit (msb) frst as shown in "figure 33. read frffftfrpp . the device id values are listed in table of id defnitions. if the one-byte address is initially set to 01h, then the device id will be read frst and then fol - lowed 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. mx25u2033e p/n: pm1743 rev. 1.3, nov. 14, 2013 29 29 table 8. id defnitions command type mx25u2033e rdid (jedec id) manufacturer id memory type memory density c2 25 32 res electronic id 32 rems/rems2/rems4 manufacturer id device id c2 32 9-20. enter secured otp (enso) the enso instruction is for entering the additional 4k-bit secured otp mode. while device is in 4k-bit secured otp mode, main array access is not available. the additional 4k-bit secured otp is independent from main array, dqgpdehxhgwrwruhxqltxhhuldoqxpehuiruwhplghqwlhuiwhuhqwhulqjwkh6hfxuhg273prghiroorz standard read or program procedure to read out the data or update data. the secured otp data cannot be updated again once it is lock-down. 7kh htxhqfh ri lxlqj (162 lqwuxfwlrq l &6 jrh orz: hqglqj (162 lqwuxfwlrq wr hqwhu 6hfxuhg 273 prgh:&6jrhkljk please note that wrsr/wrscur/wpsel commands are not acceptable during the access of secure otp region, once security otp is lock down, only read related commands are valid. 9-21. exit secured otp (exso) the exso instruction is for exiting the additional 4k-bit secured otp mode. 7kh htxhqfh ri lxlqj (;62 lqwuxfwlrq l &6 jrh orz: hqglqj (;62 lqwuxfwlrq wr h[lw 6hfxuhg 273 prgh:&6jrhkljk 9-22. read security register (rdscur) the rdscur instruction is for reading the value of security register bits. the read security register can be read at any time (even in program/erase/write status register/write security register condition) and continuously. 7khhtxhqfhrilxlqj5'6&85lqwuxfwlrql&6jrhorz:hqglqj5'6&85lqwuxfwlrq:6hfxulw5hjlwhu gdwdrxwrq62:&6jrhkljk3ohdhhh "figure 34. read security register (rdscur) sequence (command 2b)") 7khghqlwlrqriwkh6hfxulw5hjlwhuelwldehorz secured otp indicator bit. the secured otp indicator bit shows the chip is locked by factory or not. when it is "0", it indicates non-factory lock;
