functions such as the PowerPC 440 processor, the DDR SDRAM memory controller, PCI Express, and PCI
connect to the PLB. The OPB hosts lower data rate peripherals. The daisy-chained DCR provide s a lower
bandwidth path for passing status and control information between the processor and the other on-chi p cores.
The PLB has a Crossbar arbiter that supports data tr ansfer between the PLB master and two slave segments
identified as the Lo w Late ncy ( LL) and High Bandwidth ( HB) segmen ts. The LL se gment a llows PLB master s CPU
and I2O, that are adversely affected by latency, to communicate with slave devices with minimal latency. The HB
segment allows PLB masters DMA, PCI and PCI Express to exchange large blocks of data with SDRAM, PCI and
PCI Express without interfering with the low latency PLB masters.

Flash devices. It provides both direct command, address, and data access to the external device as well as a
memory-mapped linear region that generates data ac cesses. NAND Flash data is transferred on the peripheral
data bus.
Features include:
• One to four banks supported on EBC
• Direct interface to:
– Discrete NAND Flash devices (up to four devices)
– SmartMedia Card socket (22-pins)
• Device sizes:
– 4MB and larger supported for read/write access

Signal Lists
The following table lists all the external signals in alphabetical order and shows the ball (pin) number on which the
signal appears. Multiple xed signals a re shown with the de fault signal (followin g reset) not in brackets and alternate
signals in brackets. Multip lexed signals app ea r al phabe tically multiple times in the list—once for each signal name
on the ball. The page number listed gives the page in Table 7 on page 60 where the signals in the indicated
interface group be gin. In cases where signals in the same interface group (for example, Ethernet) have different
names to distinguish variations in the mode of operation, the names are separated by a comma with the primary
mode name appearing first. In cases where the signals have the same function but ar e associated with different
ports (for example, UART), the signals are separated by a slash (/). These signals are listed only once, and a ppear
alphabetically by the primary mode or primary port name.

Signal Descriptions
The PPC460GT embedded controller is packaged in a 728-ball therma lly enhanced plastic ball grid array (TE-
PBGA). The following tables describe the package level pin-out.
In the table Table 7 on page 60, 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 Table 3 on page 21 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 the following table are not accompanied by signal names that might share the same pin.
If you need to know what, if any, signals are multiplex ed with a part icu l ar signal, loo k up the name in Table 3 on
page 21. 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.
Multipurpose Signals
In addition to multiplexing, some pins such as those ca rr ying the EOTx/TCx sig nals are also multipur pose . Co ntro l
of which function a multipurpo se pin has is determined b y direction, register settings, and so on. Both functio ns are
shown separated by a slash (/).

Preliminary Data Sheet
Multimode Signals
In some cases (for example, Ethernet) the function of a pin may var y with different modes of opera tion. When a pin
has multiple signal names assigned to distinguish different modes of operation, all of the names are shown
separated by a comma.
Strapping Pins
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 95). Note that
these are not multiplexed pins since the function of the pins is not programmable.
Reserved Pins
The balls marked Reserved on this chip are not functional. Howe ve r, som e of the re se rve d balls ca nn ot be left
unconnected. Connect the balls shown in Table 6 as indicated:

Power Supply Sequencing
All the PPC460GT I/O designs are power supply sequence independent. There is no requirement that the power
supplies power up in any particular order. The following items are power sequence considerations:
• Logic power (VDD) is applied before the I/O supply voltages: The I/Os include internal supply sequencing
circuitry which ensures the output of the receiver connected to internal chip logic is 0 until the I/O power is
applied. When the logic power is on and the I/O power supplies are off, the I/O logic connected to the
associated ball neither sinks or sour ces significant curren t unless influenced by an intern al pull-up or pull-down
resistor. While the I/O supply is ramping, the state of the I/O ball is not predictable. This power sequence is not
destructive to the I/Os or internal logic and does n ot cause any functional problems.
• I/O power is applied before the logic power is applied: The outp ut driver (con nected the balls) come s up in an
unknown state (driving 1, driving 0, or tri-state) until the internal logic voltage is stable within normal operating
range. This power sequence is not destructive to the I/Os or internal logic and does not cause any functional
problems.
• External voltage should not be applied to the chip I/O balls before the associated I/O power supply voltage is
applied to the chip.
• A chip power-down cycle must complete (all I/O supply voltages and VDD are below +0.4V) before a new
power-up cycle is started
• During a power- up cycle , SysRe set and TRST inputs should be asserted low. SysReset and TRST should
remain asserted until SysClock is stable and at least 32 SysC loc k times after all power supplies are stable
within normal operating range. Failure to follow this reset sequence during the power-up cycle can result in
unpredictable operation of the chip.

Notes:
1. PCI drivers meet PCI specifications.
2. SVREF = SOVDD/2. SOVDD = +1.8V for DDR2 memory or +2.5V for DDR1 memory.
3. The analog voltages used for the on-chip PLLs can be derived from the logic voltages, but must be filtered before entering the
PPC460GT. See “Absolute Maximum Ratings” on page 70.
4. LPDL is least positive down level; MPUL is most positive up level.
5. Case temperature, TC, is measured at top center of case surface with device soldered to a circuit board.

2. SOVDD will be either +2.5V or +1.8V but not both.
3. The maximum current 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.
4. Typical current is estimated at 1GHz with VDD = +1.25V, OVDD = +3.3V, E1OVDD = +2.5V, SOVDD = +2.5V (DDR1) or +1.8V (DDR2),
and TC = +85°C with a typical process.
5. Maximum current is estimated at 1GHz with VDD = +1.3V, OVDD = +3.45V, E1OVDD = +2.6V, SOVDD = +2.6V (DDR1) or +1.9V
(DDR2), and TC = +85°C, and best-case process (which drives worst-case power).

Thermal Monitor
Thermal monitoring of the ch ip is accomplished using the PNP transistor (β ≈ 2) provided on the chip. The collector
of the transistor is connected to ground (GND). The emitter (TherMonA) and base (TherMonB) are connected to
chip pins. A voltage measurement (VBE1 and VBE2) across the TherMonA and TherMonB pins at the two current
values I1 and I2 provides the chip tem p er at ur e in °K according to the equation:
T = (q/nk)(V BE2−VBE1)/ln(I2/I1) °K where q = 1.602 176 53×10-19, n = 0.99 ± 0.05, and k = 1.380 6505×10-23.
Note: VBE2 and VBE1 should be specified in Volts. I1 and I2 can be any units of measure provided they are the
same. The small values require precision mea su rement and current sources.

Revision 1.07 – May 29, 2008
Spread Spectrum Clocking
Care must be taken when using a spread spectrum clock generator (SSCG) with the PPC460GT. 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
PPC460GT the following conditions must be met:
• The frequency deviation must not violate the minimum clock cycle time. Therefore, when operating the
PPC460GT with one or more internal clocks at their maximum supported frequency, the SSCG can only lower
the frequency.
• The maximum frequency deviation cannot exce ed −1%, and the modulation frequency cannot exceed 40kHz.
In some cases, on-board PPC460GT peripherals impose more stringent requirements.
• Use the Peripheral Bus Clock for logic that is synchronous to the peripheral bus since this clock tracks the
modulation.
• Use the DDR SDRAM MemClkOut signal since it also tracks the modulation.
• For PCI Express, the maximum spread spectrum is -0.5%, modulated between 30kHz and 33kHz. The ports
on the two ends of a link must transmit data at a rate that is within 600 parts per million (ppm) of each other at
all times. This is specified to allow bit rate clock sources with a ± 300ppm tole r anc e .
Notes:
1. The serial por t 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% toleran ce assum es that
the connected device is running at precise baud rates.
2. Ethernet operation is una ffected.
3. IIC operation is unaffected.
Important: It is up to the system designe r to ensure that any SSCG used with the PPC460GT meets the ab ove
requirements and does not adversely affect other aspects of the system.

DDR2/1 SDRAM I/O Specificat ions
The DDR SDRAM controller times its operation using the internal PLB clock signal and gen erates 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 PowerPC 460GT Embedded Processor User’s Manual).
The following DDR data is generated by means of simulation and includes logic, driver, package RLC, and lengths.
It is not to be used as a circuit design recommendation. Values are calculated over best case and worst case
processes with speed, temperature, and voltage as follows:
Best Case = Fast process: -40°C, +1.3V
Worst Case = Slow process: +105°C, +1.2
Note: In all the following DDR tables and timing diagrams, minimum values are measured under best case
conditions and maximum values are measured under worst case conditions. The signals are terminated as
indicated in the figure below for the DDR timing data in the following sections.
Figure 9. DDR SDRAM Simulation Signal Termination Model

Preliminary Data Sheet
DDR SDRAM Read Operation
Data on a read is edge aligned with the DQS. To capture the incoming data on the rising and falling edges, DQS is
delayed by the DDR controller in order to center a DQS edge on valid data.
Figure 11 shows the data read path of a single data bit. Data entering on the left is captured in the Stage 1 Flip
Flops. The four Flip Fl ops in Stage 1 capture a 4-bea t burst on the DDR interface. Data captu red on the rising edge
of DQS is stored in the even numbered Flip Flops. Likewise, data captured on the falling edge of DQS is stored in
the odd numbered Flips Flops. To latch the data in Stage 1, a delayed version of DQS is used. Initialization
software is responsible fo r tuning the DQS delay timing so that DQS is centered on va lid data. Since there is
process variation between parts and possible voltage variations on boards, read tuning is required. Fixed DQS
delay values should not be used on production systems.
The Feedback Data Capture Window in Figure 11 se lects which Flip Flop is used to store the data sampled by
DQS. Each output of this block generates a pulse to an input multiplexer. The series of four pulses selecting the
input multiplexer is initiated by a feedback signal pulse on the input of the Feedback Data Capture Window. The
DDR controller calculates when to assert the feedback signal based on when the data should be present after a
read command.
The width of the feedback pulse is one DDR 1X clock period. The internal DDR 1X clock is the same frequency as
MemClkOut0:1.
The feedback signal to the Feedback Data Capture Window is adjusted for propagation delay by the fine/coarse
delays and is able to automatically track variations in the DDR I/O due to supply voltage and temperature.
Compensation for driver/receiver variations is accomplished by driving and rece ivin g th e feed ba ck sig na l on the
external MemDCFdbkD and MemDCFdbkR pins. When properly tuned, the feedback pulse is aligned to the first
DQS in a 4-beat burst such that the rising edge of DQS is nominally centered on the feedback pulse.
Note: Using minimum trace length, connect MemDCFdbkD directly to MemDCFdbkR
The data captured in Stage 1 is relative to the DQS timing domain and is held for four MemClkOut clock cycles.
Stage 2 samples the data in Stage 1 attempting to capture the data in the DDR 1x domain. The on-time-sample
clock from the Stage 2 Store block samples the Stage 1 data at sample cycle T1, T2, T3 or T4. The sample cycle is
either selected by initialization software or can be automatically selected and adjusted by the DDR controller. The
Stage 1 data is sampled a second time by the over sample clock at a delayed sam ple point. The delay between the
on-time-sample and over sample clocks is the Over-Sampling-Guard-Band.

1. TSD and THD are measured under worst case conditions.
2. Clock speed for the values in the table is 200MHz.
3. The time values in the table include 1/4 of a cycle at 200MHz.
4. To obtain adjusted TSD and THD values for lower clock frequencies, subtract 1.25 ns from the values in the table and add 1/4
of the cycle time for the lower clock frequency (for example, TSD − 1.25 + 0.25TCYC).

Revision 1.07 – May 29, 2008
The feedback pulse is sampled with the data captured by the first DQS in the 4-beat burst. Capturing the data with
the feedback pulse is considered a hit. The DDR controller based on hits or misses by the on-time sample and over
sample clocks adjust t he sam ple cycle in order to track variations in DQS. Burst data from a sampl e hit is passed to
Stage 3.
In Stage 3 data is synchronized to the PLB clock domain and eventually driven on to the PLB bus. The data
captured on the rising and falling DQS edges is unpacked into the correct bit locations on the upper (0:63) and
lower (64:127) PLB bus. When ECC is enable, ECC checking and corrections is done after Stage 3.

In the following examp le, the data strobes (DQS) and the data are sh own 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 signa l length for all of the eight DQS signals be matched.
The following example shows the timing relation ship between SDRAM DDR Data at the input pin and storing the

Preliminary Data Sheet
Initialization
The PPC460GT provides the option for setting initial parameters based on default value s or by reading them from
a slave PROM attached to the IIC0 bus (see “Serial EEPROM” below). Some of the default values can be altered
by strapping on external pins (see “Strapping” below).
Strapping
While the SysReset input pin is low (system reset), the state of certain I/O pins is read to enable certain default
initial conditions prior to PPC460GT start-u p. The actual captu re instant is the neare st reference clock ed ge 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 conditio n s. Th es e pin s are use d fo r strap functions only during reset.
Following reset they are used for normal functions. The signal names assigne d to the pins for normal operation are
shown in parentheses following the pin number.
The following table lists the strapping pins along with their functions and strappin g options:
Serial EEPROM
During reset, init ia l con d ition s ot he r th an tho se obta in ed from the strapping pins can be read from a ROM device
connected to the IIC0 port. At the de-assertion of reset, if the Bootstrap Controller is enabled, the PPC460GT
sequentially reads 16B from the ROM de vice on the IIC0 p ort and sets t he SDR0_SDSTP0:3 register s accordingly.
The initialization settings and their default values are covered in detail in the PowerPC 460GT Embedded
Processor User’s Manual User’s Manual.
