preliminary powerpc 405gpr embedded processor data sheet 28 signal list the following table provides a summary of the number of package pins associated with each functional interface group. multiplexed pins in the table signal functional description on page 30, each external signal is listed along with a short description of the signal function. some signals are multiplexed on the same package pin (ball) so that the pin can be used for different functions. multiplexed signals are shown as a default signal with a secondary signal in square brackets (for example, gpio1[ts1e]). active-low signals (for example, ras ) are marked with an overline. it is expected that in any single application a particular pin will always be programmed to serve the same function. the flexibility of multiplexing allows a single chip to offer a richer pin selection than would otherwise be possible. in addition to multiplexing, many pins are also multi-purpose. for example, the ebc peripheral controller address pins are used as outputs by the ppc405gpr to broadcast an address to external slave devices when the ppc405gpr has control of the external bus. when, during the course of normal chip operation, an external master gains ownership 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 ppc405gpr. in this example, the pins are also bidirectional, serving as both inputs and outputs. intialization strapping one group of pins is used as strapped inputs during system reset. these pins function as strapped inputs only during reset and are used for other functions during normal operation (see strapping on page 51). note that the use of these pins for strapping is not considered multiplexing since the strapping function is not programmable. pin summary group no. of pins pci 60 ethernet 18 sdram 71 external peripheral 96 external master 9 internal peripheral 15 interrupts 7 jtag 5 system 18 total signal pins 299 ov dd 32 v dd 24 gnd 59 thermal (and gnd) 36 reserved 6 total pins 456
preliminary powerpc 405gpr embedded processor data sheet 29 pull-up and pull-down resistors pull-up and pull-down resistors are used for strapping during reset and to retain unused or undriven inputs in an appropriate state. the recommended pull-up value of 3k ? to +3.3v (10k ? to +5v can be used on 5v tolerant i/os) and pull-down value of 1k ? to gnd, applies only to individually terminated signals. to prevent possible damage to the device, i/os capable of becoming outputs must never be tied together and terminated through a common resistor. if your system-level test methodology permits, input-only signals can be connected together and terminated through either a common resistor or directly to +3.3v or gnd. when a resistor is used, its value must ensure that the grouped i/os reach a valid logic zero or logic one state when accounting for the total input current into the ppc405gpr. unused i/os strapping of some pins may be necessary when they are unused. although the ppc405gpr requires only the pull-up and pull-down terminations as specified in the signal functional description on page 30, good design practice is to terminate all unused inputs or to configure i/os such that they always drive. if unused, the peripheral, sdram, and pci buses should be configured and terminated as follows: ? peripheral interfaceperaddr0:31, perdata0:31, and all of the control signals are driven by default. terminate perready high and pererror low. ? sdramprogram sdram0_cfg[emdulr]=1 and sdram0_cfg[dce]=1. this causes the ppc405gpr to actively drive all of the sdram address, data, and control signals. ? pcithe pci pull-up requirements given in the signal functional description apply only when the pci interface is being used. when the pci bridge is unused, configure the pci controller to park on the bus and actively drive pciad31:0, pcic3:0[be3:0 ], and the remaining pci control signals by doing the following: - strap the ppc405gpr to disable the internal pci arbiter and to operate the pci interface in synchronous mode. - individually connect pciserr , pciperr , pcitrdy , and pcistop through 3.3k ? resistors to +3.3v. - terminate pcireq1:5 to +3.3v. - terminate pcireq0 [gnt ] to gnd. for selected interfaces, it is possible to turn off input receivers for some or all of the signals on that interface. control for this receiver gating is in register cpc0_cr1. when this gating capability is applied to unused signals, it is not necessary to strap them. refer to the powerpc 405gpr embedded processor users manual for details. external bus control signals all peripheral bus control signals (percs0:7 , perr/w , perwbe0:3 , peroe , perwe , perblast , holdack, extack ) are set to the high-impedance state when extreset =0. in addition, as detailed in the powerpc 405gpr embedded processor users manual , the peripheral bus controller can be programmed via ebc0_cfg to float some of these control signals between transactions and/or when an external master owns the peripheral bus. as a result, a pull-up resistor should be added to those control signals where an undriven state may affect any devices receiving that particular signal. the following table lists all of the i/o signals provided by the ppc405gpr. please refer to signals listed alphabetically on page 15 for the pin number to which each signal is assigned.

preliminary powerpc 405gpr embedded processor data sheet 43 spread spectrum clocking care must be taken when using a spread spectrum clock generator (sscg) with the ppc405gpr. this controller uses a pll for clock generation inside the chip. the accuracy with which the pll follows the sscg is referred to as tracking skew. the pll bandwidth and phase angle determine how much tracking skew there is between the sscg and the pll for a given frequency deviation and modulation frequency. when using an sscg with the ppc405gpr the following conditions must be met: ? the frequency deviation must not violate the minimum clock cycle time. therefore, when operating the ppc405gpr with one or more internal clocks at their maximum supported frequency, the sscg can only lower the frequency. ? the maximum frequency deviation cannot exceed ? 3%, and the modulation frequency cannot exceed 40khz. in some cases, on-board ppc405gpr peripherals impose more stringent requirements (see note 1). ? use the peripheral bus clock (perclk) for logic that is synchronous to the peripheral bus since this clock tracks the modulation. ? use the sdram memclkout since 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 running at precise baud rates. if an external serial clock is used the baud rate is unaffected by the modulation. 2. operation of the ppc405gpr pci bridge is unaffected by the use of a sscg. for pci frequencies of 33.33 mhz and below the pci controller supports synchronous mode operation. this is accomplished by strapping the ppc405gpr for synchronous mode pci and connecting the pci bus clock to the ppc405gpr sysclk input. for 33.33 mhz signalling, the pci specification has no limitation on the amount of frequency deviation or modulation that may be applied to the pci clock. therefore, the ppc405gpr sscg requirements stated above take precedence. at pci frequencies above 33.33 mhz, the pci controller must be operated in asynchronous mode. when in asynchronous mode, the pci bus clock must be driven into the ppc405gpr pciclk input. in this configuration the pci controller supports the 66.66 mhz pci clock specification which specifies a maximum frequency deviation of -1% at a modulation of between 30 khz and 33 khz. 3. ethernet operation is unaffected. 4. iic operation is unaffected. caution: it is up to the system designer to ensure that any sscg used with the ppc405gpr meets the above requirements and does not adversely affect other aspects of the system.

preliminary powerpc 405gpr embedded processor data sheet 51 strapping when the sysreset input is driven low by an external device (system reset), the state of certain i/o pins is read to enable default initial conditions prior to ppc405gpr start-up. the actual capture instant is the nearest sysclk 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. the recommended pull-up is 3k ? to +3.3v or 10k ? to +5v. the recommended pull-down is 1k ? to gnd. these pins are use for strap functions only during reset. they are used for other signals during normal operation. the following tables list the strapping pins along with their functions and strapping options. the signal names assigned to the pins for normal operation follow the pin number. the ppc405gpr can be used as a replacement for the ppc405gp. when the ppc405gpr is used for this purpose, it should be strapped to operate in the ppc405gpr legacy mode. this option is selected by strapping ball d20 (gpio24) low (0). if legacy mode is selected, the ppc405gpr legacy mode strapping pin assignments table should be used to determine the strapping options. to operate the chip as a ppc405gpr, strap d20 (gpio24) high (1) and use ppc405gpr new mode strapping pin assignments on page 53 to determine the strapping options. ppc405gpr legacy mode strapping pin assignments (part 1 of 2) function option ball strapping pll tuning 1 for 6 m 7 use choice 3 for 7 < m 12 use choice 5 for 12 < m 32 use choice 6 af3 uart0_tx af2 uart0_dtr ad16 uart0_rts choice 1; tune[9:0] = 1010111100 0 0 0 choice 2; tune[9:0] = 0100111000 0 0 1 choice 3; tune[9:0] = 0100110110 0 1 0 choice 4; tune[9:0] = 0100111100 0 1 1 choice 5; tune[9:0] = 0100111000 1 0 0 choice 6; tune[9:0] = 1000111100 1 0 1 choice 7; tune[9:0] = 1000111110 1 1 0 choice 8; tune[9:0] = 1011111110 1 1 1 pll forward divider 2 d16 dmaack0 b15 dmaack1 bypass mode 0 0 divide by 3 0 1 divide by 4 1 0 divide by 6 1 1 pll feedback divider 2 b14 dmaack2 c12 dmaack3 divide by 1 0 0 divide by 2 0 1 divide by 3 1 0 divide by 4 1 1 plb divider from cpu 2 p25 emctxd3 l24 emctxd2 divide by 1 0 0 divide by 2 0 1 divide by 3 1 0 divide by 4 1 1
