ppc440EPX embedded processor preliminary data sheet 56 amcc proprietary revision 1.26 ? october 15, 2007 of the external bus, these same pins are used as inputs which are driven by the external master and received by the ebc in the ppc440EPX. in this example, the pins are also bidirectional, serving both as inputs and outputs. multimode signals in some cases (for example, ethernet) the function of a pin may vary with different modes of operation. when a pin has multiple signal names assigned to distinguish different modes of operation, all of the names are shown. strapping pins one group of pins is used as strapped inputs during syst em reset. these pins function as strapped inputs only during reset and are used for other f unctions during normal operation (see ?strapping? on page 91 ). note that these are not multiplexed pins since the function of the pins is not programmable. unused i/os termination of unused receivers is generally required ; however, there are some exceptions that reduce or eliminate the need for termination. signals multiplexed with gpio: by default after reset, signals shared with gpio pins ar e configured as gpio receivers. termination however, is not needed if the gpio during initialization are configur ed as outputs. to configure as drivers, set and clear the appropriate bits in the gpiox_odr, gpiox_tcr and gpiox_or registers as described in the gpio chapter of the user?s manual. pci: when the pci bridge is unused, conf igure the pci controller to park on the bus by pulling the pc ireg0[gnt} signal low. parking forces the plb3 to pci bridge to actively drive pciad31:0 and pcic3:0[be3:0]. the remaining pci control signals must be terminated as follows: ? disable the internal pci arbiter and enable pci sync hronous mode. (see iic boot strap chapter in the user?s manual). note: synchronous mode is not supported when operating the pci bus. this mode should only be used for terminating an unused pci interface). ? individually connect pciserr, pcitrdy, and pcistop through 3k resistors to +3.3v. ? individually connect pcireq1:5 through 3k resistors to +3.3v. ? connect pcireq0[gnt] through 1k resistor to gnd. ddr: ? in 32 bit mode, termination is not needed on the upper data, strobe and mask signals when the ddr i/o and ddr controller are configured for 32 bit mode, sdr0_ddrcfg[64b32b]=0 and ddr0_14[reduc]=1. ? termination of unused ecc signals (e cc0:7, dm8, dqs8) is not needed. 440EPX ? ppc440EPX embedded processor revision 1.26 ? october 15, 2007 amcc proprietary 57 preliminary data sheet table 8. signal functional description (sheet 1 of 9) notes: 1. receiver input has hysteresis 2. must pull up (recommended value is 3 k to ov dd (eov dd for ethernet) 3. must pull down (recommended value is 1 k ) 4. if not used, must pull up (recommended value is 3 k to ov dd (eov dd for ethernet) 5. if not used, must pull down (recommended value is 1 k ) 6. strapping input during rese t; pull-up or pull-down required signal name description i/o type notes pci interface pciad00:31 address/data bus (bidirectional). i/o 3.3 v pci pcic0:3/ be0:3 pci command/byte enables . i/o 3.3 v pci pciclk provides timing to the pci interface for pci transactions. i 3.3 v pci 1, 5 pcidevsel indicates the driving device has decoded its address as the target of the current access.

the frequency deviation must not violate the minimum clock cycle time. therefore, when operating the ppc440EPX with one or more internal clocks at their ma ximum supported frequency, the sscg can only lower the frequency. ? the maximum frequency de viation cannot exceed ? 3%, and the modulation frequency cannot exceed 40 khz. in some cases, on-board ppc440EPX peripherals impose more stringent requirements. ? use the peripheral bus clock for logic that is synchron ous to the peripheral bus since this clock tracks the modulation. ? use the ddr sdram memclkout sinc e it also tracks the modulation. notes: 1. the serial port baud rates are synchronous to the modulated clock. the serial port has a tolerance of approximately 1.5% on baud rate before framing errors begin to occur. the 1.5% tolerance assumes that the connected device is runni ng at precise baud rates. 2. ethernet operation is unaffected. 3. iic operation is unaffected. important: it is up to the system designer to ensure that any sscg used with the ppc440EPX meets the above requirements and does not adversely affect other aspects of the system. 440EPX ?

october 15, 2007 amcc proprietary 85 preliminary data sheet ddr2/1 sdram i/ o specifications the ddr2/1 sdram controller times its operation using the internal plb cl ock signal and generates memclkout from the plb clock. the plb clock is an internal signal that cannot be directly observed. however, memclkout is the same frequency as the plb clock signal and is in phase with the plb clock signal. the phase skew between memclkout and the plb clock is affected by the loading on memclkout. read capture logic in the ddr controller captures read data using a de layed version of dqs and internally re- synchronizes the data to the plb clock.the ppc440EPX co ntains three independently programmable digital delay lines (dlls) that control the timing of the in dicated signals in read and write operations: 1. dqs (with respect to mem clkout) for write operations. 2. memdata, ecc, and dm (with respec t to memclkout) fo r write operations. 3. dqs (with respect to inbound memdata) for read operations. there is also a master delay line for calibration. programming details can be found in the ppc440EPX embedded processor users manual . the signals are terminated as indicated in figure 10 for the ddr timing data in the following sections. the ppc440EPX uses a clock forwarding scheme in which it drives the clock to the memory devices. data signals are divided into eight subgroups?one for each byte lane (see table 26 on page 89)? plus a ninth subgroup for the ecc byte lane. these signals includ e memdata00:63, dqs0:8, dm0:8, and ecc0:7 signals. signals within a data subgroup (byte lane) should be routed together. command bus operation the command bus (memaddr, ras , cas , we , ba, clken, banksel, me modt) is driven 180 out-of-phase with memclkout, and has no corresponding delay line. therefore, board designers must consider two different types of systems: 1) registered dimms and 2) unbuffered dimms. th e system clocking design must also be considered. to avoid crosstalk, the command bus signals and the data signals should not be routed together. board layout restrictions the paths (traces) for the data and the associated data strobe signal should be routed with the same length between the ppc440EPX and the sdram de vices, allowing the rising and falling edges of the strobe to arrive at the capture logic at the same time the da ta is in transition. all of the following timing assumes a trace velocity of 167 ps/in. board designs must meet the following criteria: ? skew on the signals in any byte lane should not exceed 50 ps (0.3 in). ? data subgroup trace lengths must be no more than 5 in. (800 ps) and have a difference of no more than 2.5 in. (400 ps). ? byte lane subgroup trace length must be no less than 1.25 in. (209 ps). for example, traces that average 3.00 in. in length and 167 ps/in., and meet the maximum 50 ps skew requirement, would have a maximum length difference of 0.3 in. so, they would be between 2.85 in. and 3.15 in. in length. if the above timing recommendations are followed, the package wire bond lengths can be ignored. clocking clocking skew to all drams must be minimized. the maximum allowed is considered to be 10 ps. because of the stringent requiremen ts on ddr device clock inputs, it is expe cted that board designers will use some type of external pll suitable to redrive the clock to the ddr sd rams. in such a system, the pll acts like a zero-delay 440EPX ? ppc440EPX embedded processor preliminary data sheet 86 amcc proprietary revision 1.26 ? october 15, 2007 insertion buffer. when using unbuffered dimms, the lo ading on the address bus will be consider ably greater than the clock (up to 18 loads for double-sided dimms). in this case, it is strongly suggested that a delay of 500 ps in the clock path so that the address/command setup time at the dimms can be met. this delay is sufficient to meet the setup time, without having to change the programmable delay (inter nal to the ppc440EPX) between the dqs/dq/dm and the clock (assuming nominal settings as specified in the ppc440EPX users manual). while the clock is now 500 ps later than the nominal dqs arrival ti me, this still falls well within the wind ow allowed by the jedec spec for t dqss ( 0.25 cycle, or 1.5 ns at 166 mhz). in the case where it is not possible to anticipate which kind of dimms may be employed in a system, it is always safe to use this 500 ps clock delay, since registered dimms (the least heavily loaded) will have more th an enough margin (almost 1/2 cyc le) to accommodate the slight decrease in address hold time. termination model figure 10. ddr sdram simulation signal termination model 10pf 10pf memclkout memclkout 120 : 50 : 30pf addr/ctrl/data/dqs/dm (ddr1) v tt = sov dd /2 ppc440EPX addr/ctrl (ddr2) note: this diagram illustrates the model of the ddr sdram interface used when generating simulation timing data. it is not a recommended physical circuit design for this interface. an actual interface design will depend on many factors, including the type of memory used and the board layout. ddr2 sdram on-die termination impedance setting for all ddr2 applications, the on-die termination (odt) impedance value must be set to 75 ohms in the dimm extended mode register (emr) in order to optimize th e data transmission during memory write operations. signal path output current (ma) i/o h (maximum) i/o l (maximum) write data memdata00:63 10 10 ecc0:7 10 10 dm0:8 10 10 memclkout 10 10 memaddr00:13 10 10 ba0:2 10 10 ras 10 10 cas 10 10 we 10 10 banksel0:1 10 10 clken 10 10 dqs0:8 10 10 memodt0:1 10 10 440EPX ?

below). some of the default values can be altered by strapping on external pins (see ?strapping? below). strapping while the sysreset input pin is low (system reset), the state of cert ain i/o pins is read to enable certain default initial conditions prior to ppc440EPX start-up. the actu al capture instant is the nearest reference clock edge before the deassertion of reset. these pins must be strapped using external pull-up (logical 1) or pull-down (logical 0) resistors to select the desired default conditions . these pins are used for strap functions only during reset. following reset they are used for normal functions. the signal names assigned to the pins for normal operation are shown in parentheses following the pin number. note: when uart0_dcd , uart0_dsr and uart0_cts are used functionally, the pin straps should be isolated from the uart transceiver during reset as the transceiv er may overdrive the pin straps and cause the ppc440EPX to read incorrect straps. the following table lists the strapping pins al ong with their functions and strapping options: function option pin strapping c28 ( uart0_dcd ) c29 ( uart0_dsr ) a29 ( uart0_cts ) serial device is disabled. ea ch of the six options (a?
