table provides a summary of the number of package pins associated with each functional interface group. Pin Summary Group No. of Pins Non multiplexed 215 Multiplexed 33 Total Signal Pins 248 OVDD 43 VDD 16 Gnd 53 Thermal (and Gnd) 25 Reserved 0 Total Pins 385 In the table "Signal Functional Description" on page 33, each external signal is listed along with a short description of the signal function. Active-low signals (for example, RAS) are marked with an overline. Please see "Signals Listed Alphabetically" on page 13 for the pin (ball) number to which each signal is assigned. Multiplexed Pins Some signals are multiplexed on the same package pin (ball) 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 multiplexed with a particular signal, look up the name in "Signals Listed Alphabetically" on page 13. 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, in the PCI interface PCIC3:0/BE3:0 serves as both Command and Byte Enable signals. In this example, the pins are also bidirectional, serving as both inputs and outputs. Initialization 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 "Initialization" on page 50). Note that the use of these pins for strapping is not considered multiplexing since the strapping function 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 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. 3/19/03 31 Preliminary PowerPC 405EP Embedded Processor Data Sheet 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 PPC405EP. Unused I/Os Strapping of some pins may be necessary when they are unused. Although the PPC405EP requires only the pull-up and pull-down terminations as specified in the "Signal Functional Description" on page 33, 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 interface--PerAddr03:31, PerData00:15, and all of the control signals are driven by default. Terminate PerReady high. * SDRAM--Program SDRAM0_CFG[EMDULR]=1 and SDRAM0_CFG[DCE]=1. This causes the PPC405EP to actively drive all of the SDRAM address, data, and control signals. * PCI--The 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 PCIAD31:00, PCIC3:0/BE3:0, and the remaining PCI control signals by doing the following: - Strap the PPC405EP to disable the internal PCI arbiter. - Individually connect PCISErr, PCIPErr, PCITRDY, and PCIStop through 3.3k resistors to +3.3V. - Terminate PCIReq1:2 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 405EP Embedded Processor User's Manual for details. External Bus Control Signals All peripheral bus control signals (PerCS0:4, PerR/W, PerWBE0:1, PerOE, PerWE, PerBLast) are set to the high-impedance state when ExtReset=0. In addition, as detailed in the PowerPC 405EP Embedded Processor User's Manual, the peripheral bus controller can be programmed via EBC0_CFG to float some of these control signals between transactions. 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 PPC405EP. Please refer to "Signals Listed Alphabetically" on page 13 for the pin number to which each signal is assigned. 32 3/19/03 Preliminary PowerPC 405EP Embedded Processor Data Sheet Signal Functional Description (Part 1 of 6) Secondary multiplexed signals are shown in brackets.

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 PPC405EP the following conditions must be met: * The frequency deviation must not violate the minimum clock cycle time. Therefore, when operating the PPC405EP 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 PPC405EP 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 PPC405EP PCI Bridge is unaffected by the use of an SSCG. The PCI controller must be operated in asynchronous mode. When in asynchronous mode, the PCI bus clock must be driven into the PPC405EP 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 PPC405EP meets the above requirements and does not adversely affect other aspects of the system. 44 3/19/03 Preliminary PowerPC 405EP Embedded Processor Data Sheet Peripheral Interface Clock Timings Parameter PCIClk input frequency (asynchronous mode) PCIClk period (asynchronous mode) Min Max Units Note 1 66.66 MHz 15 Note 1 ns PCIClk input high time 40% of nominal period 60% of nominal period ns PCIClk input low time 40% of nominal period 60% of nominal period ns - 2.5 MHz EMC0MDClk output frequency EMC0MDClk period 400 - ns EMC0MDClk output high time 160 - ns EMC0MDClk output low time 160 - ns PHY0Tx0:1Clk input frequency 2.5 25 MHz PHY0Tx0:1Clk period 40 400 ns PHY0Tx0:1Clk input high time 35% of nominal period - ns PHY0Tx0:1Clk input low time 35% of nominal period - ns 2.5 25 MHz PHY0Rx0:1Clk input frequency PHY0Rx0:1Clk period 40 400 ns PHY0Rx0:1Clk input high time 35% of nominal period - ns PHY0Rx0:1Clk input low time 35% of nominal period - ns PerClk output frequency - 66.66 MHz PerClk period 15 - ns PerClk output high time 45% of nominal period 55% of nominal period ns PerClk output low time 45% of nominal period 55% of nominal period ns 0.3 ns PerClk clock edge stability (phase jitter, cycle to cycle) Note: 1.

The SDRAM command interface is configurable through SDRAM0_TR[LDF] to provide a 2 to 4 cycle delay before the command is used by SDRAM. 2. SDRAM I/O timings are specified relative to a MemClkOut terminated into a lumped 10pF load. 3. SDRAM interface hold times are guaranteed at the PPC405EP package pin. System designers must use the PPC405EP IBIS model (available from www.chips.ibm.com) to ensure their clock distribution topology minimizes loading and reflections, and that the relative delays on clock wiring do not exceed the delays on other SDRAM signal wiring. 4. PerClk rising edge at package pin with a 10pF load trails the internal PLB clock by approximately 0.8ns. 5. I/O H is specified at 2.4 V and I/O L is specified at 0.4 V.

Strapping When the SysReset input is driven low (system reset), the state of certain I/O pins is read to enable default initial conditions prior to PPC405EP start-up. The actual capture instant is the nearest system 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. 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 table lists the strapping pins along with their functions and strapping options. The signal names assigned to the pins for normal operation appear below the pin number. Strapping Pin Assignments Function IIC EEPROM controller If the controller is enabled, 32 bytes of configuration data are read from the EEPROM. Option P04 UART0_Tx Disable 0 Enable 1 EEPROM address (P04 = 1) or Boot ROM width (P04 = 0) When P04 = 1, these pins set the high-order two bits of the EEPROM base address. When P04 = 0, these pins indicated the width of the boot ROM. Ball Strapping N02 UART0_RTS Y17 SysErr High order EEPROM base address bits Address bit Address bit 8 bits 0 0 16 bits 0 1 reserved 1 0 reserved 1 1 EEPROM During reset, configuration values other than the internal default values can be read from a serial EEPROM connected to the IIC port. The association of bits in the EEPROM with the configuration values and their default values are covered in detail in the PowerPC 405EP Embedded Processor User's Manual. Caution: If P04 is strapped to 1, and the EEPROM is not connected or is defective, the PPC405EP remains in the reset state and will not boot.
