The PPC405 processor is a fixed-point, 32-bit RISC unit.
Features include:
• Five-stage pipeline with single-cycle execution of most instructions, including loads and stores
• Separate, configurable 16 KB D- and I-caches, both two-way set associative
• Thirty-two 32-bit general purpose registers (GPRs)
• Unaligned load/store support
• Hardware multiply/divide
• Parity detection and reporting for the instruction cache, data cache, and translation look-aside buffer (TLB)

Internal Buses
The PPC405EX contains four internal buses: the processor local bus (PLB), the Advanced High-Performance Bus
(AHB), the on-chip peripheral bus (OPB), and the device control register (DCR) bus. High performance devices
such as the processor, the DDR SDRAM memory controller, PCI Express, the Ethernet MAL, and DMA utilize the
PLB. Lower bandwidth I/O interfaces such as communications and timer interfaces utilize the OPB. The daisy-
chained DCR bus provides a lower bandwidth path for passing status and control information between the
processor and the other on-chip peripheral functions.
PLB
The Processor Local Bus (PLB) is a high-performance on-chip bus used to connect PLB-equipped master and
slave devices to the PPC405 CPU. It provides a 128-bit data path with 64-bit addressing and operates up to
200MHz. There are bridges between the PLB and the OPB.
Features include:
• Separate and simultaneous 6.4GB/s read and write data paths
• Decoupled address and data buses
• Address pipelining
• Late master request abort capability
• Hidden (overlapped) bus request/grant protocol

DMA Controller
The Direct Memory Access (DMA) controller is a Processor Local Bus (PLB) master that enables faster data
transfer between memory and peripherals than is possible under program control. The 4-channel DMA controller
handles data transfers between memory and peripherals and from memory-to-memory. Each channel has an
independent set of registers needed for data transfer: a control register, a source address register, a destination
address register, and a transfer count register.

In the table “Signal Functional Description” on page 38, each external signal is listed along with a short description
of the signal function. Active-low signals (for example, Halt) are marked with an overline. See the preceding table,
“Signals Listed Alphabetically” on page 17, for the pin (ball) number to which each signal is assigned.
Shared Pins
Some signals are shared on the same package 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 might share the same pin.
If you need to know what, if any, signals are shared with a particular signal, look up the name in “Signals Listed
Alphabetically” on page 17. It is expected that in any single application a particular pin will always be programmed
to serve the same function. The flexibility of sharing allows a single chip to offer a richer pin selection than would
otherwise be possible.
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 65). 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 3kΩ to +3.3V 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 logical zero or logical one state when accounting for the total input current into the
PPC405EX.

1. The analog voltages can be derived from the +1.2V and +2.5V supplies, but must be filtered as shown below before entering
the PPC405EX. Use a separate filter for each voltage. This circuit can be used for AVDD, AHVDD , SAVDD, and EAVDD. Use
AGND with AVDD and AHVDD. Use SAGND with SAVDD. Use EAGND with EAVDD. These analog grounds must be brought
out and connected to the digital ground plane at the filter capacitor. Keep all wire lengths as short as possible.

PPC405EX – PowerPC 405EX Embedded Processor
Spread Spectrum Clocking
Preliminary Data Sheet
Care must be taken if using a spread spectrum clock generator (SSCG) with the PPC405EX. This controller uses a
PLL for clock generation inside the chip. The accuracy with which the PLL follows the SSCG is called tracking
skew. The PLL bandwidth and phase angle determine how much tracking skew exists between the SSCG and the
PLL for a given frequency deviation and modulation frequency. If using an SSCG with the PPC405EX the following
conditions must be met:
• The frequency deviation must not violate the minimum clock cycle time. Therefore, when operating the
PPC405EX with one or more internal clocks at their maximum supported frequency, the SSCG can only lower
the frequency.
• The maximum frequency deviation must not exceed −3%, and the modulation frequency must not exceed
40kHz. In some cases, on-board PPC405EX peripherals impose more stringent requirements (see Note 1).
• Use the peripheral bus clock for logic that is synchronous to the peripheral bus because this clock 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, assuming that the connected device is
running at precise baud rates. If an external serial clock is used, baud rate is unaffected by the modulation.
2. Ethernet operation is unaffected.
3. IIC operation is unaffected.
Caution: The system designer must ensure that any SSCG used with the PPC405EX meets these requirements
and does not adversely affect other aspects of the system.

PPC405EX – PowerPC 405EX Embedded Processor
DDR 1/2 SDRAM I/O Specifications
Preliminary Data Sheet
The DDR SDRAM controller times its operation using the internal PLB clock signal and generates MemClkOut from
the PLB clock. The PLB clock is an internal signal that cannot be directly observed. However MemClkOut is the
same frequency as the PLB clock signal and is in phase with the PLB clock signal.
Note: MemClkOut can be advanced with respect to the PLB clock by means of the SDRAM0_CLKTR
programming register. In a typical system, users advance MemClkOut by 90°. This depends on the specific
application and requires a thorough understanding of the memory system in general (refer to the DDR
SDRAM Controller chapter in the PPC405EX Embedded Processor User’s Manual).
The signals are terminated as indicated in Figure 6 for the DDR timing data in the following sections.

Note: This diagram illustrates the model of the DDR SDRAM interface used when generating simulation timing data.
It is not a recommended physical circuit design for this interface. An actual interface design will depend on many
factors, including the type of memory used and the board layout.
DDR2 SDRAM On-Die Termination Impedance Setting
For all DDR2 applications, the On-Die Termination (ODT) impedance value must be set to 75 ohms in the DIMM
Extended Mode Register (EMR) in order to optimize the data transmission during memory write operations.

DDR SDRAM Write Operation
The rising edge of MemClkOut aligns with the first rising edge of the DQS signal on writes. The following data is
generated by means of simulation and includes logic, driver, package RLC, and lengths. Values are calculated
over best case and worst case processes with speed, junction temperature, and voltage as follows:

DDR SDRAM Read Operation
The Read of the incoming Data from the SDRAM is done on the rising and falling edges of the differential DQS
signal. The Data must be centered to these edges for correct operation.
The PPC405EX can delay with very fine granularity the DQS through register programming.
DDR SDRAM MemClkOut0 and Read Clock Delay
In order to accommodate timing variations introduced by the system designs using this chip, the three-stage data
path shown below is used to eliminate metastability and allow data sampling to be adjusted for minimum latency.
The data is stored in the eight Flip Flops of the Stage 1, such that it can be transferred later within a 8x period.

In the following example, the data strobes (DQS) and the data are shown to be coincident. There is actually a slight
skew as specified by the SDRAM specifications, and there can be additional skew due to loading and signal
routing. It is recommended that the signal length for all of the DQS signals be matched.
The following example shows the timing relationship between SDRAM DDR Data at the input pin and storing the
data in Stage 1.

Initialization
Preliminary Data Sheet
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 in order to enable default
initial conditions before PPC405EX start-up. The actual instant of capture 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 3kΩ to +3.3V, or 10kΩ to +5V. The
recommended pull-down is 1KΩ to GND. These pins are only used for strap functions 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.
