ppc440EP embedded processor revision 1.26 ? april 25, 2007 data sheet signal descriptions the ppc440EP embedded controller is packaged in a 456-ball enhanced plastic ball grid array (e-pbga). the following tables describe the package level pinout. in the table ?signal functional description? on page 50, each i/o signal is listed along with a short description of its function. active-low signals (for example, ras ) are marked with an overline. please see ?signals listed alphabetically? on page 17 for the pin (ball) number to which each signal is assigned. multiplexed signals some signals are multiplexed on the same pin so that the pin can be used for different functions. in most cases, the signal names shown in this table are not accompanied by signal names that may be multiplexed on the same pin. if you need to know what, if any, signals are multiple xed with a particular signal, look up the name in ?signals listed alphabetically? on page 17. 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 otherwise be possible. the circuit type for multiplexed signals is shown as ?multiplex.? the actual circuit type is the same as the primary signal. multipurpose signals in addition to multiplexing, some pins are also multi- purpose. for example, the ebc peripheral controller address pins (peraddr) are used as outputs by the ppc440EP to br oadcast an address to external slave devices when the ppc440EP 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 ppc440EP. in this example, the pins are also bidirectional, serving both as inputs and outputs. table 5. pin summary group no. of pins total signal pins 304 av dd 1 sav dd 1 sagnd 1 agnd 1 ov dd 18 sv dd 18 v dd 32 gnd 80 total power pins 152 reserved 0 total pins 456 amcc proprietary 49 440EP ? ppc440EP embedded processor data sheet revision 1.26 ? april 25, 2007 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 functions during no rmal operation (see ?strapping? on page 80). note that these are not multiplexed pins since the function of the pins is not programmable. 50 amcc proprietary 440EP ? ppc440EP embedded processor revision 1.26 ? april 25, 2007 data sheet table 6. signal functional description (sheet 1 of 9) notes: 1. receiver input has hysteresis 2. must pull up (recommended value is 3k to 3.3v ) 3. must pull down (recommended value is 1k ) 4. if not used, must pull up (recommended value is 3k to 3.3v) 5. if not used, must pull down (recommended value is 1k ) 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 3.3v pci pcic0:3/be0:3 pci command/byte enables . i/o 3.3v pci pciclk provides timing to the pci inte rface for pci transactions. i 3.3v pci pcidevsel indicates the driving device has decoded its address as the target of the current access. i/o 3.3v pci pciframe driven by the current master to indicate beginning and duration of an access. i/o 3.3v pci pcignt0 /req indicates that the specified agent is granted access to the bus. when the internal arbiter is enabled, output is pcignt0 . when the internal arbiter is disabled, output is req . o 3.3v pci pcignt1:5 indicates that the specified agent is granted access to the bus. used only when internal pci arbiter enabled. o 3.3v pci pciidsel used as a chip select during configuration read and write transactions. i 3.3v pci pciint level sensitive pci interrupt. o 3.3v pci pciirdy indicates initiating agent?s ability to complete the current data phase of the transaction. i/o 3.3v pci pcipar even parity. i/o 3.3v pci pciperr reports data parity errors duri ng all pci transactions except a special cycle. i/o 3.3v pci pcireq0 /gnt indicates to the pci arbiter that the specified agent wishes to use the bus. when the internal arbiter is enabled, input is pcireq0 . when internal arbiter is disabled, input is gnt . i 3.3v pci pcireq1:5 an indication to the pci arbiter that the specified agent wishes to use the bus. used only when internal pci arbiter enabled. i 3.3v pci pcireset brings pci device registers and logic to a consistent state. o 3.3v pci pciserr reports address parity errors, data parity errors on the special cycle command, or other catastrophic system errors. i/o 3.3v pci pcistop current target is requesting the master to stop the current transaction. i/o 3.3v pci pcitrdy t arget agent?s ability to complete the current data phase of the transaction. i/o 3.3v pci amcc proprietary 51 440EP ?

ppc440EP embedded processor revision 1.26 ? april 25, 2007 data sheet spread spectrum clocking care must be taken when using a spread spectrum cloc k generator (sscg) with the ppc440EP. this controller uses a pll for clock generation inside the chip. the accura cy 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 ppc440EP the following conditions must be met: ? the frequency deviation must not violate the minimum clock cycle time. therefore, when operating the ppc440EP with one or more internal clocks at their maximum supported fr equency, the sscg can only lower the frequency. ? the maximum frequency de viation cannot exceed ? 3%, and the modulation frequency cannot exceed 40khz. in some cases, on-board ppc440EP 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 running 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 ppc440EP meets the above requirements and does not adversely affect other aspects of the system. amcc proprietary 65 440EP ?

below). some of th e default values ca n 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 ppc440EP start-up. the actual ca pture 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 defau lt conditions. these pins are used fo r 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. the following table lists the strapping pins al ong with their functions and strapping options: eeprom during reset, initial conditions other than those obtained from the strapping pins can be read from a rom device connected to the iic0 port. at the de-assertion of reset, if the boots trap controller is enabled, the ppc440EP sequentially reads 16 bytes from the rom device on t he iic0 port and sets the sdr0_sdstp0, sdr0_sdstp1, sdr0_sdstp2 and sdr0_sdstp3 registers accordingly. the initialization settings and their default values are covered in detail in the powerpc 440EP user?s manual . table 23. strapping pin assignments function option ball strapping r25 (uart0_dcd ) u26 (uart0_dsr ) v26 (uart0_cts ) serial device is disabled. ea ch of the six options (a? f) is a combination of boot source, boot-source width, and clock frequency specifications. refer to the iic bootstrap controller chapter in the ppc440EP embedded processor user?s manual for details. a 000 b 001 c 010 d 011 e 100 f 110 serial device is enabled. the option being selected is the iic0 slave address that will respond with configuration data. note: if reading of configuration data from the serial device fails, the ppc440EP defaults to configuration x. g (0xa8)101 h (0xa4)111 amcc proprietary 81 440EP ?
