rev. 1.0 / feb. 2005 5 1 hy5ds283222bf(p) pin description pin type description ck, /ck input clock: ck and /ck are differen tial clock inputs. 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 activa tes, 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 ba nks 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 disable. cke must be maintained high throughout read and write accesses. input buffers, excluding ck, /ck and cke are disabled during powe r down. input buffers, excluding cke are disabled during self refresh. cke is an sstl_2 input, but will detect an lvcmos low level after vdd is applied. /cs input chip select : enables or disables all inputs except ck, /ck, cke, dqs and dm. all com- mands are masked when cs is registered high. cs provides for external bank selection on systems with multiple banks. cs 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 pre- charge 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/write commands, to select one location out of the memory array in the respective bank. a8 is sampled during a precharge command to determine whether the precharge applies to one bank (a8 low) or all banks (a8 high). if only one bank is to be precharg ed, the bank is selected by ba0, ba1. the address inputs also provide the op code during a mode register set command. 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. dm0 ~ dm3 input input data mask: dm(0~3) is an input mask signal for write data. input data is masked when dm is sampled high along with that in put data during a write access. dm is sam- pled on both edges of dqs. although dm pi ns are input only, the dm loading matches the dq and dqs loading. dm0 corresponds to the data on dq0-q7; dm1 corresponds to the data on dq8-q15; dm2 corresponds to the data on dq16-q23; dm3 corresponds to the data on dq24-q31. d q s 0 ~ d q s 3 i / o data strobe: output with read data, input with write data. edge aligned with read data, centered in write data. used to capture wr ite data. dqs0 corresponds to the data on dq0-q7; dqs1 corresponds to the data on dq 8-q15; dqs2 corresponds to the data on dq16-q23; dqs3 corresponds to the data on dq24-q31 dq0 ~ dq31 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 / feb. 2005 15 1 hy5ds283222bf(p) 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 operation. except for ck e, inputs are not re cognized as valid until after vref is applied. cke is an sstl_2 input, but will detect an lv cmos low level after vdd is applied. maintaining an lvcmos low level on cke during power-up is required to guarant ee that the dq and dqs outputs will be in the high-z state, where they will remain until driven in normal operation (by a read access). after all po wer supply and reference volt- ages are stable, and the clock is stable, the ddr sdram requ ires a 200us delay prior to applying an executable com- mand. 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, txsrd(dll locking time) sh ould be satisfied for read command. after the mode reg- ister 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 (i .e. to program operating para meters without resetting the dll) must be performed. following these cycles , the ddr sdram is ready for normal operation. 1. apply power - vdd, vddq, vtt, vref in the following po wer up sequencing and attemp t to maintain cke at lvc- mos low state. (all the other input pins may be undefined. no power sequencing is specified during power up or power down given the following cirteria : ? vdd and vddq are driven from a single power converter output. ? vtt is limited to 1.44v (ref lecting vddq(max)/2 + 50mv vref variation + 40mv vtt variation). ? vref tracks vddq/2. ? a minimum resistance of 42 ohms (22 ohm series resist or + 22 ohm parallel resistor - 5% tolerance) limits the input current from the vtt supply into any pin. if the above criteria cannot be met by the system design, then the following sequencing and voltage relationship 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 of clock are required 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 vddq after or with vdd < vdd + 0.3v vtt after or with vddq < vddq + 0.3v vref after or with vddq < vddq + 0.3v

rev. 1.0 / feb. 2005 18 1 hy5ds283222bf(p) 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 eigh t (where ai is the most significant column address bit for a given configuration). the remaining (least significant) address bit(s) is (are) used to select the starting location within the block. the programmed burst length 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 definitionon 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 / feb. 2005 19 1 hy5ds283222bf(p) 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 latency can be programmed 5 / 4 clocks. 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 this device supports both half strength driver and matched impedance driver, inte nded for lighter load and/or point-to- point environments. half strength driver is to define about 50% of full drive st rength which is specified to be sstl_2, class ii, and matched impedance driver, about 30% of full drive strength.
