PowerPC 405GP Embedded Processor Data Sheet
General Purpose IO (GPIO) Controller
• Controller functions and GPIO registers are programmed and accessed via memory-mapped OPB bus
master accesses
• 23 GPIOs are pin-shared with other functions. DCRs control whether a particular pin that has GPIO
capabilities acts as a GPIO or is used for another purpose. The 23 GPIOs are multiplexed with:
- 7 of 8 chip selects
- All seven external interrupts
- All nine instruction trace pins
• Each GPIO output is separately programmable to emulate an open-drain driver (i.e., drives to zero, threestated 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 triggered or level-sensitive
• Positive or negative active
• Non-critical or critical interrupt to processor core
• Programmable critical interrupt priority ordering
• Programmable critical interrupt vector for faster vector processing
10/100 Mbps Ethernet MAC
• Capable of handling full/half duplex 100Mbps and 10Mbps operation
• Uses the medium independent interface (MII) to the physical layer (PHY not included on chip)
JTAG
• IEEE 1149.1 test access port
• IBM RISCWatch debugger support
• JTAG Boundary Scan Description Language (BSDL)

PowerPC 405GP Embedded Processor Data Sheet
Pin Lists
The PPC405GP embedded controller is available as a 456-ball or a 413-ball E-PBGA package. The 456-ball
package is available in two sizes—35 millimeters and 27 millimeters. The 413-ball package size is 25
millimeters. In this section there are three tables that correlate the external signals to the physical package
pin (ball) on which they appear.
The following table lists all the external signals in alphabetical order and shows the ball number on which the
signal appears. Multiplexed signals are shown with the default signal (following reset) not in brackets and the
alternate signal in brackets. Multiplexed signals appear alphabetically multiple times in the list—once for each
signal name on the ball. The page number listed gives the page in “Signal Functional Description” on page 34
where the signals in the indicated interface group begin.

Multiplexed Pins
In the table “Signal Functional Description” on page 34, 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 PPC405GP to broadcast an address to external slave devices when
the PPC405GP 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 PPC405GP. 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 55). Note
32
PowerPC 405GP Embedded Processor Data Sheet
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 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 state when accounting for the total input current into
the PPC405GP.
Unused I/Os
Strapping of some pins may be necessary when they are unused. Although the PPC405GP requires only the
pull-up and pull-down terminations as specified in the “Signal Functional Description” on page 34, 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—PerAddr0:31, PerData0:31, and all of the control signals are driven by default.
Terminate PerReady high and PerError low.
• SDRAM—Program SDRAM0_CFG[EMDULR]=1 and SDRAM0_CFG[DCE]=1. This causes the
PPC405GP 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 PCIAD31:0, PCIC3:0[BE3:0], and the remaining PCI control signals by doing the
following:
- Strap the PPC405GP to disable the internal PCI arbiter and to operate the PCI interface in
synchronous mode.
- Individually connect PCISErr, PCIPErr, PCITRDY, and PCIStop through 3.3kΩ resistors to +3.3V.
- Terminate PCIReq1:5 to +3.3V.
- Terminate PCIReq0[Gnt] to GND.
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
405GP Embedded Processor User’s 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 PPC405GP. Please refer to “Signals Listed
Alphabetically” on page 16 for the pin number to which each signal is assigned.

PowerPC 405GP Embedded Processor Data Sheet
Spread Spectrum Clocking
Care must be taken when using a spread spectrum clock generator (SSCG) with the PPC405GP. 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 PPC405GP the following conditions must be met:
• The frequency deviation must not violate the minimum clock cycle time. Therefore, when operating the
PPC405GP 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 PPC405GP 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.
Please refer to the application note Using a Spread Spectrum Clock Generator with the PowerPC 405GP for
additional details. This application note is available on the IBM Microelectronics web site at
http://www.chips.ibm.com.
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 PPC405GP 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 PPC405GP for synchronous mode PCI and connecting the PCI bus
clock to the PPC405GP 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
PPC405GP 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 PPC405GP 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 PPC405GP meets the above
requirements and does not adversely affect other aspects of the system.

Note:
1. In asynchronous PCI mode the minimum PCIClk frequency is 1/8 the PLB Clock. Refer to the PowerPC 405GP Embedded Processor User’s Manual for more information.
2. In synchronous PCI mode the PCI clock is derived from SysClk and the PCIClk input pin is unused.
3. TOPB is the period in ns of the OPB clock. The maximum OPB clock frequency is 50 MHz for 200MHz parts and 66.66MHz for
266MHz parts.

I/O Specifications—200MHz
Notes:
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 PPC405GP package pin. System designers must use the
PPC405GP 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.

PowerPC 405GP Embedded Processor Data Sheet
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 PPC405GP 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 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 operation. The following table lists the
strapping pins along with their functions and strapping options. The pin for the 456-ball package is listed first
(for example, AF3), followed by the corresponding pin for the 413-ball package (for example, U8), which
appears as AF3/U8.

Note:
1. The tune bits adjust parameters that control PLL jitter. The recommended values minimize jitter for the PLL implemented in the
PPC405GP. These bits are shown for information only; and do not require modification except in special clocking circumstances
such as spread spectrum clocking. For details on the use of Spread Spectrum Clock Generators (SSCGs) with the PPC405GP,
visit the technical documents area of the IBM PowerPC web site.
2. Not all combinations of dividers produce valid operating configurations. Frequencies must be within the limits specified in “Clocking
Specifications” on page 46. Further requirements are detailed in the Clocking chapter of the PowerPC 405GP Embedded
Processor User’s Manual.
3. Additional consideration must be given to pins that normally function as Trace signals. Improved design margin can be gained by
using tri-state buffers instead of strapping resistors, and minimizing trace lengths and stubs.
