rev. 1.0 /july. 2008 5 release h5du6462ctr series pin description pin type description ck, /ck input clock: ck and /ck are differential clock inpu ts. all address and control input signals are sampled on the crossing of the positive edge of ck and negative edge of /ck. output (read) data is referenced to the crossings of ck and /ck (both directions of crossing). cke input clock enable: cke high activates, and cke low deactivates internal clock signals, and device input buffers and output drivers. taking cke low provides precharge power down and self refresh operation (all banks idle), or active power down (row active in any bank). cke is synchronous for power down entry and exit, and for self refresh entry. cke is asynchronous for self refresh exit, and for output dis- able. cke must be maintained high throughout read and write accesses. input buff- ers, excluding ck, /ck and cke are disabl ed during power down. input buffers, excluding cke are disabled during self re fresh. cke is an sstl_2 input, but will detect an lvcmos low level after v dd is applied. /cs input chip select: enables or disables all inputs except ck, /ck, cke, dqs and dm. all com- mands are masked when chip select is registered high. chip select provides for exter- nal bank selection on systems with multiple ba nks. chip select is considered part of the command code. ba0, ba1 input bank address inputs: ba0 and ba1 define to which bank an active, read, write or precharge command is being applied. a0 ~ a11 input address inputs: provide the row address for active commands, and the column address and auto precharge bit for read/w rite commands, to select one location out of the memory array in the respective bank. a10 is sampled during a precharge command to determine whether the precharge applies to one bank (a10 low) or all banks (a10 high). if only one bank is to be precharged, the bank is selected by ba0, ba1. the address inputs also provide the op code during a mode register set com- mand. ba0 and ba1 define which mode register is loaded during the mode register set command (mrs or emrs). /ras, /cas, / we input command inputs: /ras, /cas and /we (along with /cs) define the command being entered. d m (ldm,udm) input input data mask: dm is an input mask signal for write data. input data is masked when dm is sampled high along with that input data during a write access. dm is sampled on both edges of dqs. although dm pins are input only, the dm loading matches the dq and dqs loading. for the x16, ldm corr esponds to the data on dq0-q7; udm cor- responds to the data on dq8-q15. dqs (ldqs,udqs) i/o data strobe: output with read data, input wi th write data. edge al igned with read data, centered in write data. used to capture wr ite data. for the x16, ldqs corresponds to the data on dq0-q7; udqs corres ponds to the data on dq8-q15. dq i/o data input / output pin: data bus v dd / v ss supply power supply for internal circuits and input buffers. v ddq / v ssq supply power supply for output buffers for noise immunity. v ref supply reference voltage for inputs for sstl interface. nc nc no connection.

rev. 1.0 /july. 2008 10 release h5du6462ctr series power-up sequence and device initialization ddr sdrams must be powered up and initialized in a pred efined manner. operational pr ocedures other than those specified may result in undefined operat ion. power must first be applied to v dd , then to v ddq , and finally to vref (and to the system vtt). vtt must be applied after v ddq to avoid device latch-up, which may cause permanent dam- age to the device. v ref can be applied anytime after v ddq , but is expected to be no minally coincident with vtt. except for cke, inputs are not re cognized as valid until after v ref is applied. cke is an sstl _2 input, but will detect an lvcmos low level after v dd is applied. maintaining an lvcmos low le vel on cke during power-up is required to guarantee that the dq and dqs outputs will be in the high-z state, where they will remain until driven in normal oper- ation (by a read access). after all power supply and reference voltages are stable, and the clock is stable, the ddr sdram requires a 200us delay prior to applying an executable command. once the 200us delay has been satisfied, a deselect or nop command should be applied, and cke should be brought high. following the nop command, a precharg e all command should be applied. next a extended mode register set command should be issued for the ex tended mode register, to enable the dll, then a mode register set command should be issued for the mode re gister, to reset the dll, and to program the operating parameters. after the dll reset, t xsrd (dll locking time) should be satisfied for read command. after the mode regis- ter set command, a precharge all command should be appl ied, placing the device in the all banks idle state. once in the idle state, two auto refresh cycles must be performed. additionally, a mode register set command for the mode register, with the reset dll bit deactivated lo w (i.e. to program operating parameters without resetting the dll) must be performed. following these cycl es, the ddr sdram is ready for normal operation. 1. apply power - v dd , v ddq , vtt, v ref in the following power up sequencing and attempt to maintain cke at lvc- mos low state. (all the other input pins may be undefined.) ?v dd and v ddq are driven from a single power converter output. ? vtt is limited to 1.44v (reflecting v ddq (max)/2 + 50mv v ref variation + 40mv vtt variation. ?v ref tracks v ddq /2. ? if the above criteria cannot be met by the system desi gn, then the following sequen cing and voltage relation- ship must be adhered to during power up. 2. start clock and maintain stable clock for a minimum of 200usec. 3. after stable power and clock, apply nop condition and take cke high. 4. issue extended mode register set (emrs) to enable dll. 5. issue mode register set (mrs) to reset dll and set devi ce to idle state with bit a8=high. (an additional 200 cycles(t xsrd ) of clock are requir ed for locking dll) 6. issue precharge commands for all banks of the device. 7. issue 2 or more auto refresh commands. 8. issue a mode register set command to initia lize the mode register with bit a8 = low voltage description sequencing voltage relationship to avoid latch-up v ddq after or with v dd < v dd + 0.3v vtt after or with v ddq < v ddq + 0.3v v ref after or with v ddq < v ddq + 0.3v

rev. 1.0 /july. 2008 12 release h5du6462ctr series mode register set (mrs) the mode register is used to store the various operating mo des such as /cas latency, addressing mode, burst length, burst type, test mode, dll reset. the mode register is pr ogramed via mrs command. this command is issued by the low signals of /ras, /cas, /cs, /we and ba0. this command can be issued only when all banks are in idle state and cke must be high at least one cycle before the mode regi ster set command can be issued. two cycles are required to write the data in mode register. during the mrs cycle, an y command cannot be issued. once mode register field is determined, the information will be he ld until reset by another mrs command. ba1 ba0 a11 a10 a9 a8 a7 a6 a5 a4 a3 a2 a1 a0 0 0 operating mode cas latency bt burst length a2 a1 a0 burst length sequential interleave 0 0 0 reserved reserved 001 2 2 010 4 4 011 8 8 1 0 0 reserved reserved 1 0 1 reserved reserved 1 1 0 reserved reserved 1 1 1 reserved reserved a3 burst type 0sequential 1interleave a6 a5 a4 cas latency 00 0 reserved 00 1 reserved 01 0 2 01 1 3 10 0 reserved 10 1 1.5 11 0 2.5 11 1 reserved ba0 mrs type 0mrs 1emrs a12~a9 a8 a7 a6~a0 operating mode 0 0 0 valid normal operation 0 1 0 valid normal operation/ reset dll 0 0 1 vs vendor specific test mode - - - - all other states reserved
rev. 1.0 /july. 2008 13 release h5du6462ctr series burst definition burst length & type read and write accesses to the ddr sdram are burst orient ed, with the burst length be ing programmable. the burst length determines the maximum number of column locations that can be acce ssed for a given read or write com- mand. burst lengths of 2, 4 or 8 locations are available for both the sequential and the interleaved burst types. reserved states should not be used, as unknown operatio n or incompatibility with future versions may result. when a read or write command is issued, a block of column s equal to the burst length is effectively selected. all accesses for that burst take place within this block, mean ing that the burst wraps within the block if a boundary is reached. the block is uniquely selected by a1-ai when the burst length is set to two, by a2 -ai when the burst length is set to four and by a3 -ai when the burst length is set to eight (where ai is the most significant column address bit for a given configuration). the remaining (least significant) a ddress bit(s) is (are) used to select the starting location within the block. the programmed burst leng th applies to both read and write bursts. accesses within a given burst may be programmed to be either sequential or interleaved; th is is referred to as the burst type and is selected via bit a3. the ordering of acce sses within a burst is determined by the burst length, the burst type and the starting column addres s, as shown in burst definition table burst length starting address (a2,a1,a0) sequential interleave 2 xx0 0, 1 0, 1 xx1 1, 0 1, 0 4 x00 0, 1, 2, 3 0, 1, 2, 3 x01 1, 2, 3, 0 1, 0, 3, 2 x10 2, 3, 0, 1 2, 3, 0, 1 x11 3, 0, 1, 2 3, 2, 1, 0 8 000 0, 1, 2, 3, 4, 5, 6, 7 0, 1, 2, 3, 4, 5, 6, 7 001 1, 2, 3, 4, 5, 6, 7, 0 1, 0, 3, 2, 5, 4, 7, 6 010 2, 3, 4, 5, 6, 7, 0, 1 2, 3, 0, 1, 6, 7, 4, 5 011 3, 4, 5, 6, 7, 0, 1, 2 3, 2, 1, 0, 7, 6, 5, 4 100 4, 5, 6, 7, 0, 1, 2, 3 4, 5, 6, 7, 0, 1, 2, 3 101 5, 6, 7, 0, 1, 2, 3, 4 5, 4, 7, 6, 1, 0, 3, 2 110 6, 7, 0, 1, 2, 3, 4, 5 6, 7, 4, 5, 2, 3, 0, 1 111 7, 0, 1, 2, 3, 4, 5, 6 7, 6, 5, 4, 3, 2, 1, 0
rev. 1.0 /july. 2008 14 release h5du6462ctr series cas latency the read latency or cas latency is the delay in clock cy cles between the registration of a read command and the availability of the first burst of output data. the latenc y can be programmed 2 or 2.5 clocks for ddr266/333 and 3 clocks for ddr400 product. if a read command is registered at clock edge n, and the la tency is m clocks, the data is available nominally coincident with clock edge n + m. reserved states should not be used as unknown operation or incompatibility with future versions may result. dll reset the dll must be enabled for normal operation. dll enable is required during power up initialization, and upon return- ing to normal operation after having disabled the dll for th e purpose of debug or evaluation. the dll is automatically disabled when entering self refresh oper ation and is automatically re-enabled upon exit of self refresh operation. any time the dll is enabled, 200 clock cycles must occur to al low time for the internal clock to lock to the externally applied clock before an any command can be issued. output driver impedance control the normal drive strength for all outputs is specified to be sstl_2, class ii. hynix also supports a half strength driver option, intended for lighter load and/or point-to-point envi ronments. selection of the half strength driver option will reduce the output drive strength by 50% of that of the full strength driver. i-v curves for both the full strength driver and the half strength driver are included in this document.
rev. 1.0 /july. 2008 15 release h5du6462ctr series extended mode register set (emrs) the extended mode register controls fu nctions beyond those controlled by the mode register; these additional func- tions include dll enable/disable, output dr iver strength selection(optional). thes e functions are contro lled via the bits shown below. the extended mode register is programmed via the mode register set command (ba0=1 and ba1=0) and will retain the stored information until it is programmed again or the device loses power. the extended mode register must be loaded when all banks are idle and no bursts are in progress, and the controller must wait the specified time before in itiating any subsequent operation. viol ating either of these requirements will result in unspecified operation. ba1 ba0 a11 a10 a9 a8 a7 a6 a5 a4 a3 a2 a1 a0 0 1 operating mode 0* ds dll a0 dll enable 0enable 1disable ba0 mrs type 0mrs 1emrs a1 output driver impedance control 0 full strength driver 1 half strength driver * this part do not support/qfc functi on, a2 must be programmed to zero. an~a3 a2~a0 operating mode 0 valid normal operation _ _ all other states reserved
