General Purpose IO (GPIO) Controller
• Controller functions and GPIO registers are programmed and accessed via memory-ma pped OPB bus
master accesses
• All GPIOs are pin-shared with other functions. DCRs control whether a pa rticular p in that has GPIO cap abil-
ities acts as a GPIO or is used fo r another purpose.
• Each GPIO output is separately programmable to emulate an open-drain driver (i.e., drives to zero, three-
stated if output bit is 1)
Universal Interrupt Controller (UIC)
The Universal Interrupt Controller (UIC) provides the control, status, and communications necessary between the
various sources of interrupts and the local PowerPC processor.
Features include:
• Supports seven external and 19 internal interrupts
• Edge-trigger ed or level-sensitive
• Positive or negative active
• Non-critical or critical interrupt to processor core
• Programmab le critical interrupt priority ordering
• Programmab le critical interrupt vector for faster vector processing

Data Sheet
Signal List
The following table provides a summary of the number of package pins associated with each functional interface
group.
In the table “Sign al Functional Description” on p age 31, 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 mu ltiplexed on th e sa me 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 accompanie d by signal names that may be multiplexed
on the same pin. If you need to know what, if any, signals are multiplexed with a par ticular 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 sign als. In this e xample, the pins are also bidire ctional, serving as both
inputs an d outputs.
Initialization Strapping
One group of pins is used as strapped inputs during system reset. These pins function as strapped inputs only
during reset a nd are used for o ther functions during normal operatio n (see “Initialization” on page 49). 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 re set and to retain unused or undriven inputs in an
appropriate state. The recommended pull-up value of 3kΩ to +3.3V (10kΩ to +5V can be used on 5V tolerant I/Os)
and pull-down value of 1kΩ 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 st ate 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 p age 31, good desig n practice
is to terminate all unused input s or to configure I/Os such that they always drive. If unused, the periph eral, SDRAM,
and PCI buses should be configured and terminated as follows:
• Peripheral interface—PerA ddr03:31, PerDa t a00:1 5, and all of the control signals are driven by default. Pull
up PerReady.
• 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 PC I bridge is unuse d, configure the PCI controller to p ark on the bus and
actively drive PCIAD31:00, PCIC3:0/BE3:0, and the remaining PCI control signa ls by doing the following:
- Strap the PPC405EP to disable the internal PCI arbiter.
- Individually pull up PCISErr, PCIPErr, PCITRD Y, and PCIStop through 3.3kΩ resistors to +3.3V.
- Pull up PCIReq1:2 thr ou g h a 3.3kΩ resistor to +3.3V.
- Pull down PCIReq0/Gnt through a 1kΩ resistor to GND.
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 whe n 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.

Note:
1. The maximum current and power values listed above are not guaranteed to be the highest obtainable. These values are
dependent on many factors including the type of applications running, clock rates, use of internal functional capabilities, external
interface usage, case temperature, and the power supply voltages. Your specific application can produce significantly different
results. VDD (logic) current and power are primarily dependent on the applications running and the use of internal chip functions
(DMA, PCI, Ethernet, and so on). OVDD (I/O) current and power are primarily dependent on the capacitive loading, frequency, and
utilization of the external buses. The following information provides details about the conditions under which the values in the table
above could be obtained:
a. In general, there would be four PCI devices, an external bus master on the peripheral bus, and external wrap-back on the
Ethernet port. For IODD measurements, PLB = 133.3MHz, OPB = PerClk = 66.6MHz, and PCI = SysC lk = 33.3MHz.
b. Typical current and power are characterized at VDD = +1.8V, OVDD = +3.3V, and TC = +36°C while running various
applications under the Linux operating system.
c. Maximum current and power are characterized at VDD = +1.9V, OVDD = +3.6V, and TC = +85°C while running applications
designed to maximize CPU power consumption. An external PCI master heavily loads the PCI bus with transfers targeting
SDRAM while the internal DMA controller further increases SDRAM bus traffic.

Data Sheet
Spread Spectrum Clocking
Care must be taken when using a spread spectrum clock generator (SSCG) with the PPC405EP. 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 frequen cy deviation cannot exceed −3%, and the modulation frequency cannot exceed
40kHz. In some cases, on-board PPC405EP peripherals impose more stringent requirement s (see No te 1).
• Use the peripheral bu s clock (PerClk) for logic that is synchronous to the perip h er al bu s sinc e th is 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 approx-
imately 1.5% on baud rate before framing errors begin to occur. The 1.5% tolerance assumes that the
connected device is running a t precise baud rates. If an external serial clock is used the baud rate is unaf-
fected 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 s pecification 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.

Initialization
The following describes the method by which initial chip settings are established when a system reset occurs.
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 con ditions. The recommended pull-up is 3kΩ to +3.3V or 10kΩ to +5V. The
recommended pull-down is 1KΩ to GND. These pins are use for strap functions only during reset. They are used
for other signals during normal oper ation. The following table lists the stra pping pins along with their functions and
strapping options. The signal names assigned to the pins for normal operation appear below the pin number.
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.
Note: 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.
