ppc405cr ? powerpc 405cr embedded processor revision 1.02 ? january 11, 2005 amcc 21 data sheet signal descriptions the ppc405cr embedded controller is packaged in a 316-ba ll enhanced plastic ball grid array (e-pbga). the fol- lowing table provides a summary of th e number of package pins associated with each functional interface group. multiplexed pins in the table ?signal functional description? on page 23, each i/o signal is listed along with a short description of the signal function. some signals are multip lexed onto the same package pin (ball) so that the pin can be used for dif- ferent functions. multiplexed signals are shown as a defa ult 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 app lication 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 ot herwise 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 ppc405cr to broadcast an address to external slave devices when the ppc405cr 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 ar e used as inputs which are driven by the external master and received by the ebc in the ppc405cr. intialization strapping one group of pins is used as strapped inputs during syst em reset. these pins function as strapped inputs only dur- ing reset and are used for other functions during normal operation (see ?strapping? on page 39). note that these are not multiplexed pins since the function of the pins is not programmable. 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 termin ated signals. to prevent possible damage to the device, i/os capabl e of becoming outputs must never be tied together and terminated through a common resistor. table 5. pin summary group no. of pins sdram 71 external peripheral 97 external master 9 internal peripheral 15 interrupts 7 jtag 5 system 18 total signal pins 222 av dd 1 ov dd 16 v dd 16 gnd 40 thermal (and gnd) 16 reserved 5 total pins 316
ppc405cr ? powerpc 405cr embedded processor 22 amcc revision 1.02 ? january 11, 2005 data sheet if your system-level test meth odology permits, input-only signals c an 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 stat e when accounting for the total input current into the ppc405cr. unused i/os strapping of some pins may be necessary when they are unused. although the ppc405cr requires only the pull- up and pull-down terminations as specified in the ?s ignal functional description? on page 23, good design practice is to terminate all unused inputs or to configure i/os such that they always drive. if unused, the peripheral and sdram buses should be configured and terminated as follows: ? peripheral interface?peraddr0:31, perdata0:31, and a ll of the control signals are driven by default. termi- nate perready high and pererror low. ? sdram?program sdram0_cfg[emdulr]=1 and sdra m0_cfg[dce]=1. this causes the ppc405cr to actively drive all of the sdram address, data, and control signals. 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 405cr embedded processor user?s manual , the peripheral bus controller can be prog rammed via ebc0_cfg to float some of these control signals between transact ions and/or when an external master owns the peripheral bus. as a result, a pull- up resistor should be added to those control signals wher e an undriven state may affe ct any devices receiving that particular signal. the following table lists all of the i/o signals provided by the ppc405cr. please refer to ?signals listed alphabet- ically? on page 11 for the pin number to which each signal is assigned.

ppc405cr ? powerpc 405cr embedded processor revision 1.02 ? january 11, 2005 amcc 33 data sheet spread spectrum clocking care must be taken when using a spread spectrum clock generator (sscg) with the ppc405cr. this controller uses a pll for clock generation inside the chip. the accu racy with which the pll follows the sscg is referred to as tracking skew. the pll bandwidth and phase angle dete rmine 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 ppc405cr the following conditions must be met: ? the frequency deviation must not violate the minimum clock cycle time. therefore, when operating the ppc405cr with one or more internal clocks at thei r 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 ppc405cr peripheral s 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 modu lated clock. the serial port has a tolerance of approx- imately 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 unaf- fected by the modulation. 2. iic operation is unaffected. caution: it is up to the system designer to ensure th at any sscg used with the ppc405cr meets the above requirements and does not adversely affect other aspects of the system.
