3 SB710 Power on Sequence and Timing
3.1
Power Up and Down Sequences
Simple diagrams of the SB710 power up sequences are shown in Figure 3-1 and Figure 3-2 below. A
power detection circuit is integrated into the SB710. This circuit will monitor SB PWR_GOOD and will
assert A_RST# and LDT_RST# for as long as SB PWR_GOOD is false. After SB PWR_GOOD has been
asserted, A_RST#, followed by LDT_RST#, will be de-asserted. Table 4-1 shows the timing requirements
referenced in Figure 3-1 through Figure 3-5. Besides the illustrated requirements, it is also required that
the ramp time for any rail be less than 40ms.

Description
+3.3V_S5 to +1.2V_S5
+3.3V_S5 to resume reset (RSMRST#).
Resume reset (RSMRST#) rise time (10% to 90%). SB710 has a Schmitt trigger
input with de-bouncing logic on this pin, so the value is relaxed relative to earlier
AMD SB designs.
RSMRST# de-asserted to Start of RTCCLK output from SB710.
SB PWR_GOOD de-assertion to NB_PWRGD de-assertion delay.
SB PWR_GOOD assertion to NB_PWRGD assertion delay when using the
SB710 NB_PWRGD output. This parameter is the internal delay of the SB. The
system board design may add additional delay due to loading and trace length.
The acceptable delay including system layout / loading is 1 ms maximum..
SB PWR_GOOD rise time (10% to 90 %). See Note 3. SB710 has a Schmitt
trigger with de-bouncing logic on this pin, so the value is relaxed relative to
earlier AMD SB designs.

2 below. The SB710 power rails are grouped in four different voltages:
I. +5 V, which includes V5_VREF
II. +3.3 V, which includes VDDQ, VDD33_18 (IDE mode)
III. +1.2 V, which includes AVDDCK_1.2V, AVDD_SATA, PLLVDD_SATA, PCIE_PVDD,
PCIE_VDDR, CKVDD_1.2V
IV. +1.8 V
Note 2: V5_VREF is used in the SB710 for the 5-V PCI signal tolerance. VDDQ (+3.3 V) &
VDD33_18 (3.3 V) must not exceed V5_VREF by more than 0.6 V at any time during ramp up,
steady state, or ramp down. The suggested circuit below should be used to maintain
relationship between V5_VREF and VDDQ and VDD33_18.
Figure 3-3: Circuit for Maintaining Proper Relationship between +V5_VREF and VDDQ
Note 3: The SB710 will latch the straps after rising edge of SB PWR_GOOD only once. With
debouncing of SB PWR_GOOD, the latching of strap will occur at approximately ~10ms after
the rising edge of SB PWR_GOOD.
Note 4: Typical time between A_RST# and PCIRST# is 75 ns. The measurement should be
done at 10% of both signals. Loading on the motherboard may cause the measurement at
90% be more than the spec.
Note 5: The KBRST# should be de-asserted before A_RST# (LDT_RST#) is de-asserted.
Note 6: Type II Standard and Debug straps will be latched after SB PWR_GOOD is asserted.
Type I straps are latched on resume reset rising edge. Refer to Section 4: SB710 Strap
Information for strap timing.
Note 7: The SB710 will not monitor the ALLOW_LDTSTP signal on power up. This signal is
only used on C3 transitions.
Note 8: The PCI Clock may be stable before T11 min. under some conditions; however in all
cases, the PCI Clock is guaranteed to be stable only between T11 min and max.
Note 9: The SB710 will monitor internally the power down events and protect the internal
circuit during the power down event. This includes power down during the S3, S4, and S5
states. During an unexpected power failure or G3 state, the relationship between the 1.2 V
(VDD) and SB Power Good should be maintained to protect the internal logic of the SB710.
Note 10: The following figure shows the timing of SB PWR_GOOD de-asserted to RSMRST#
de-asserted during a power down sequence. However, this timing only applies to S0 to G3
state transition, because G3 state is where both signals are inactivated.

Figure 3-4: Timing for SB PWR_GOOD De-asserted to RSMRST# De-asserted
Note 11: On first power up, G3 Æ S5, or after RSMRST# assertion, the LDT_STP# will be asserted
with CPU_VDDIO power. On subsequent power up, S5 Æ S0, the timing on T9B will apply.
Figure 3-5: Timing for LDT_STP# assertion on first power up (G3 Æ S5)
Note 12: The S5_3.3V ramp down should be controlled to achieve a slew rate of 8mV/ µS or lower.

4 SB710 Strap Information
There are two kinds of strap-latching logic, Type I and Type II. Type I straps will be latched on G3 to S5
transition on rising edge of RSMRST#. Type II straps are latched on S5 to S0 transition after rising edge
of PWR_GOOD assertion.

Straps are also classified in two groups, standard and debug. Straps in the standard group are used for
selecting on power up the desired modes of ASIC operation and additional optional features. Straps in
debug group are for debugging at the system-level, mainly during the pre-production stage. Debug straps
should have provision for PU or PD so they can be configured to either option when required for debug
purposes.
Table 4-1 and Table 4-2 show the function of every strap signal in the design. All straps are defined such
that in the most likely scenario of operation, they will be set to the recommended (or safest) values. The
values shown in the Description column are the external board strap values, with 3.3V being a pull-up
(PU) and 0V a pull-down (PD).

Note: The pin has an internal integrated pull-up or pull-down resistor that is not enabled by default. The pin’s default
function does not require a pull-up or pull-down. However, if the pin is used for an alternate function and a pull-up or
pull-down is required, the internal resistor can be enabled by the indicated register.

Functional Description
LDT Power Good
LDT Reset#
LDT Reset#: Reset signal to the CPU.
Assertion of LDT_RST# causes the CPU to transition into a low power
state and to de-assert MEMCLKEA/B and assert MEMREST_L.
Assertion of LDT_RST# takes place sometime after SB PWR_GOOD
has been de-asserted.
De-assertion of LDT_RST# allows MEMRESET_L to be de-asserted
and MEMCLK to be enabled. De-assertion of LDT_RST# takes place
sometime after SB PWR_GOOD has been asserted.
Assertion of LDTSTOP# on the CPU causes it to enter C3, or
S1/S2/S3/S4/S5. Assertion takes place: (a) for S1/S2/S3/S4/S5: after
SUS_STAT# is asserted; (b) for C3: after the STPGNT message is
received by the system.
De-assertion of LDTSTOP_L causes the CPU to return to C0 or S0
state. De-assertion takes place following a wake-up event:
(a) in S1: at an interval (programmed by an SB register) after deassertion of CPU_STP#;
(b) in S2: after SLP_S2 is de-asserted;
(c) in S3/S4/S5: after SB PWR_GOOD is asserted;
(d) in C3: at an interval (programmed by an SB register)
Starting with RS78x, NB will control the LDT_STP# during C state.
Processor Hot: Similar to TALERT#. When it is asserted, it can
generate SCI or SMI to OS/BIOS.

Notes: (1) The USB_HSD[11:0]P and USB_HSD[11:0]N signals are used for connecting internal or external USB
devices via USB Port connectors. These ports are handled by users and are subject directly to ESD events
to either the connector, the device, or to the pins themselves. The USB_HSDP and USB_HSDN signals that
may be exposed to the user through an USB port connection must have ESD protection. Please refer to the
Product Advisory PA_SB700AU1 posted on AMD’s OEM Resource Center for further details on ESD device
specifications.
(2) The USB_FSD[13:12]P and USB _FSD[13:12]N signals are used only for connecting to internal devices.
They support only full or low, but not high speed devices.

Note: The SB710 does not support the flash controller function. The flash controller should be disabled
by BIOS, and the interface can only be used for IDE function (or as GPIOs, in case of the IDE data bus
bits). Portions of the pin names below that imply flash controller function should be ignored. See the AMD

Note: For each port there is a pin (SATA_IS) for sensing the status of the external interlock switch. If the
motherboard implements SATA interlock switches, it should connect the statuses of the switches to those pins. The
SB710 will sense the statuses of those pins and can generate a PME or interrupt when the statuses change.
Normally, an inter-lock switch is required for supporting hot plug.

Power Button: The Power Button will cause an SMI# or SCI to
indicate a system request to go to a sleep state. If the system is
already in a sleep state, this signal will cause a wake event. If
PWRBTN# is pressed for more than 4 seconds, this will cause an
unconditional transition (power button override) to the S5 state with
only the PWRBTN# available as a wake event. Override will occur
even if the system is in the S1 state. This signal has an internal pullup resistor.
SB power good input
Assertion of PWR_GOOD by the SB power good circuit on the
motherboard indicates that power supplies to the SB are valid.
Assertion takes place sometime after NB Power Good is asserted.
De-assertion of PWR_GOOD by the SB power good circuit indicates
that the power supplies to the SB are NOT valid. De-assertion takes
place sometime after SLP_S3# or SLP_S5#’s assertion, or after
Power Supply Power Good is de-asserted.

De-assertion of SLP_S3# turns on power to non-critical components
when system transitions from S3, S4, or S5 back to S0. Deassertion takes place sometime after a wake-up event has been
triggered.
S5 Sleep Power plane control Assertion of SLP_S5# shuts power off to non-critical components
when system transitions to S4 or S5 state. Assertion takes place
sometime after CPU_STP# is asserted.
De-assertion of SLP_S5# turns on power to non-critical components
when transitioning from S4/S5 back to S0 state. De-assertion takes
place sometime after a wake-up event is triggered.
SMBus Alert / Thermal Trip / General Event 2
Thermal Trip: Signal indicates to the SB710 that a thermal trip has
occurred. Its assertion will cause the SB710 to transition the system
to S5 immediately, without waiting for the STPGNT message from
the processor.
Suspend Status Assertion by the SB710 indicates that the system will be entering a
low-power state soon. The signal is monitored by those devices with
memory that needs to switch from normal refresh to suspend
refresh mode when the system transitions to a low-power state.
Assertion takes place after the Stop Grant message from the CPU is
received by the system.
De-assertion by the SB710 indicates that the system is exiting a low
power state now and is returning to S0. De-assertion takes place
after LDT_STP# is de-asserted.
Temperature Monitor Input 3/ Thermal Alert / GPIO 64
Thermal Alert: The signal is a thermal alert to the SB710. SB710
can be programmed to generate an SMI#, SCI, or IRQ13 through
GPE, or generate an SMI# without GPE in response to the signal’s
assertion. See the AMD SB700/SB710/SB750 Register Reference
Guide for details.
S3 State: Assertion of S3_STATE by the SB710 indicates to the
power supply that the system has transitioned into S3 state.
Asserted after the Sleep S3 command is completed. De-assertion
indicates that the system is leaving S3 state. De-assertion takes
place after SUS_STAT# is de-asserted.

PCI Express Wake /General Event 8
PCI Express Wake: WAKE# signal is required for PCI-E devices.
The PCI-E interface is off the NB, but the ACPI WAKE# is controlled
by SB. This signal is routed from the PCI-E device/slot to the SB.
Note: the WAKE# is in S5 domain so it is active when the system is
in S5 state. Care must be taken when plugging-in in the PCI-E
devices: the system should be transitioned in to G3 state (S5 Power
OFF) before a PCI-E device is installed. Plugging in a PCI-E device
when the system is in S5 state may cause the system to wake up.
That is because the WAKE# signal driven by the PCI-E device may
transition momentarily to active state when the device is installed
but has not been initialized to drive the signal in inactive state.
(Note: Hot plugging of PCI-E devices is not supported in the PC
architecture as, given the physical design of the interface, power will
be interrupted during installation.)
S2 Sleep control: Assertion of SLP_S2 shuts off clocks when
system transitions to S2 state, and it takes place sometime after
CPU_STP# is asserted.
De-assertion of SLP_S2 turns on clocks when system transitions
from S2 back to S0, and it takes place sometime after a wake-up
event has been triggered.
ALLOW_LDTSTP: It is an input from NB to allow assertion of
LDT_STP#. When ALLOW_LDTSTP is de-asserted, SB710 cannot
assert LDT_STP#. ALLOW_LDTSTP can be used to implement
stutter mode operation for the CPU. Starting with RS78x, NB will
control the LDT_STP# during C state. In this configuration, SB can
drive ALLOW_LDTSTP to inform NB when it can assert LDT_STP#.

The EXTEVENT/GEVENT/GPM/GPOC pins of the SB710 are multiplexed with other functions. For
information on how to configure the EXTEVENT/GEVENT/GPM/ GPOC pins for the desired functions,
see the AMD SB700/SB710/SB750 Register Reference Guide.
The table below lists all the EXTEVENT/GEVENT/GPM/GPOC pins on the SB710. The Default Type
column shows the state of the pin (default function) after de-assertion of the PCI host bus reset
(A_RST#), which happens after power up or after system reset. Signals that are in input state after reset
will be tri-state (TS) if they do not have any internal PU (pull-up) or PD (pull-down). For pins that have PU
or PD internally, their states after reset will depend on the PU or PD: for signals with PU, the state will be
HIGH and for signals with PD the state will be LOW. The PU and PD shown are enabled by default after
PCI Reset and can be disabled by System BIOS.
Abbreviations: PU = pull-up, PD = pull-down, OD = open drain, I/O = Input/Output, TS = tri-state

The table below lists all the GPIO pins on the SB710. The Default Type column shows the state of the pin
(default function) after de-assertion of the PCI host bus reset (A_RST#), which happens after power up or
after system reset. Signals that are in input state after reset will be tri-state (TS) if they do not have any
internal PU (pull up ) or PD (Pull Down). For pins that have PU or PD internally, their states after reset will
depend on the PU or PD: for signals with PU, the state will be HIGH and for signals with PD the state will
be LOW. The PU and PD shown are enabled by default after PCI Reset and can be disabled by System
BIOS.

Notes: For information on how to configure the GPIO pins, see the AMD SB700/SB710/SB750 Register
Reference Guide. Notice that the IMC GPIOs can also be used as general purpose GPIOs.
* The “default function” and the “default state” refer to function and state of the pin after
deassertion of PCI host bus reset (A_RST#), i.e., right after system power up or reset.
◊ The IMC PWM and SMBus functions are not available if the IMC is disabled via the strap setting
on AZ_RST#.
§ To avoid corrupting the ROM type strap settings, IMC_GPO[17:16] must not be driven from an
external source until after RSMRST# had been de-asserted.

Integrated Micro-Controller (IMC)
Note: With the exception of Advanced Clock Calibration (ACC) and Infrared (IR) controller support, other
Integrated Micro-Controller (IMC) features are not supported by the SB710. The IMC interface must be
enabled for IR controller support. Systems that require ACC support must have provision for strap option
on the IMC ENABLE strap (on pin LPCCCLK0). GPIOs on the IMC interface can be used like any other
GPIO pins, with IMC enabled or disabled. If not used, pins on this interface should be terminated in the
manner described in the AMD SB700/SB710/SB750 Schematic Review Checklist.
If IMC is disabled, the register field PMIO_BB[5] must be set to 1 to allow the IMC GPIOs to maintain
state in S4 and S5.
The SMBUS is independent of the IMC controller. It is usable even when the IMC is disabled. When the
IMC is enabled, the SMBUS controller is shared between the host and the IMC. The IMC can control the
SMBus and the IMC interfaces if they are not used by the host, and that is achieved through software.

Functional Description
Resume Reset from Motherboard –
Assertion of RSMRST# resets all SB710 registers to their
default values. It also causes all reset signals originating
from the SB710 (A_RST#, PCIRST#, LDT_RST#,
AZ_RST#, AC_RST#) to be issued. RSRMT# should be
asserted when system power is being applied. Type-I straps
are captured on the rising edge of RSRMT# during its deassertion. RSMRST# should be de-asserted sometime after
S5 power is up, and should stay de-asserted until system
power is removed.

8.1.1 USB Power Management
An advanced power management capability interface compliant with PCI Bus Power Management
Interface Specification Revision 1.1 is incorporated into the EHCI. This interface allows the EHCI to be
placed in various power management states, offering a variety of power savings for a host system.
Table 8-1 highlights the EHCI support for power management states and features supported for each of
the power management states. An EHCI implementation may internally gate-off USB clocks and suspend
the USB transceivers (low power consumption mode) to provide these power savings.

SMI#/SCI Generation
Certain system events are routable between SMI# and SCI. When an event is routed to SMI#, an SMI#
assertion message will be sent by the SB710 to the processor and it will enter SMM space. The SMI
status remains active until the EOS bit is set. When the EOS is set, SMI# de-assertion message will be
sent to the processor for at least 4 PCICLK cycles. If the event is routed to SCI, then BIOS can route it to
any of the legacy interrupts (except IRQ8) or INT21 in the case of IOAPIC.

LPC ISA Bridge
8.3.1 LPC Interface Overview
The Low Pin Count (LPC) bus interface is a cost-efficient, low-speed interface designed to support lowspeed legacy (ISA, X-bus) devices. The LPC interface essentially eliminates the need of ISA and X-bus in
the system. A typical setup of the system with LPC interface is shown in Figure 8-2 below. Here the ISA
bus is internal to SB710 and is used for connecting to the legacy DMA logic. The LPC controller connects
to the A-Link bus on one side and the LPC and SPI bus on the other side.
Figure 8-2: A Typical LPC Bus System
Examples of LPC devices include Super I/O (floppy-disk controller, keyboard controller), BIOS, audio,
TPM, and system management controller. BIOS ROM can also be populated on the SPI interface.
SB710 can support FWH, LPC, or SPI type BIOS ROM. The ROM selection is determined by two strap
pins during RSMRST# assertion. In addition to the straps, software can change the ROM selection
through programming in the PMIO registers. SB710 SPI interface is designed to allow ROM sharing with
an external device such as an Ethernet MAC to save BOM cost. (Note: Device that shares the ROM
must follow AMD SPI ROM sharing specification).
Figure 8-3: LPC control signals diagram (TBA)
Note that the ISA interface is only used for legacy DMA operation. LPC host controller has the A-Link
interface on one side and LPC interface on the other. Some LPC signals are used for power management
in mobile systems and are therefore optional. A more detailed description of each signal is given in

section 7.2.
The host controller supports memory and IO read/write, DMA read/write, and bus master memory/IO
read/write. It supports up to two bus masters and 7 DMA channels. A bus master or DMA agent uses
LDRQ pin to assert bus master or DMA request. The host controller uses LFRAME# to indicate the start
or termination of a cycle. The following table shows a list of cycles supported by the host controller,
initiator, data flow direction, and their PCI counterparts.

The host controller has a SERIRQ (Serial IRQ) pin, which is used by peripherals that require interrupt
support. All legacy interrupts are serialized on this pin, and then decoded by the host controller and sent
to the interrupt controller for processing. Please refer to the Serial IRQ Specification (Rev 5.4) for detailed
description on serial IRQ protocol.

Note: The IMC interface must be enabled by the IMC_ENABLE strap for IR support. Whether the IMC
interface is enabled or not, the IMC GPIO pins can be used as general purpose GPIOs without IMC

8.4.1 Consumer Infrared Controller
The integrated infrared controller in SB710 provides the interface to connect two IR receivers and two IR
transmitters. The two IR receivers are for learning IR Data and receiving IR Data, and the two IR
transmitters are for transmitting IR data. The controller has the ability to support wake from S5, S4, S3 or
S1 states, and is capable of storing and returning the wake identification code to the IR driver.

AMD SB710 Databook
Only the demodulators for the receivers are integrated with the controller, and the modulators for the
transmitters need to be supported on the system board. Other features include full Vista Media Center
support, and support for 10-m long range receiver and 10-cm wide band receiver.
Note: Use of Windows Media Center or Microsoft Windows compatible infrared and RF remote control
units or receivers to interact directly or indirectly with the Windows Media Center user interface on a
personal computer or other computing device that includes this AMD product may implement the claimed
subject matter of US Patent 5,640,160.
8.5
Real Time Clock
The Real Time Clock (RTC) is used for updating a computer’s time. In addition to that, it also generates
interrupts for periodic events and pre-set alarm. The SB710’s RTC includes a 256-byte CMOS RAM,
which is used to store the configuration of a computer, such as the number and type of floppy drive,
graphics adapter, base memory, checksum value, etc. The RTC supports leap year date adjustment in
hardware.
8.5.1 Functional Blocks of RTC
The internal RTC is made of two parts: one is an analog circuit, powered by a battery VBAT, and the
other part is a digital circuit, powered by a main power VDD. Figure 9-4 shows the block diagram of the
internal RTC.
When writing data (time, alarm or date) to the RTC directly (by passing them through BIOS routine or
operating system API calls), the application should verify that the data is in BCD format; binary mode is
not supported. The data should be valid date/time, as the validation of the data can only be performed at
the software level.

SATA (Serial ATA) Controller
The integrated Serial ATA controller processes host commands and transfers data between the host and
Serial ATA devices. It supports six independent Serial ATA channels. Each channel has its own Serial
ATA bus and supports one Serial ATA device. On transfer rate, SATA controller supports both Serial ATA
Generation I (1.5 Gb/s) and Generation II (3.0 Gb/s). Figure 9-5 below is a diagram for the SATA block.
The SB710 SATA controller can operate in three modes:
1) All six channels can be configured as IDE mode. In this configuration, the programming interface of
two of the channels (4 and 5) is under the PATA controller
2) Four channels configured as SATA AHCI and channel 4 and 5 configured in IDE mode. In this
configuration, the programming interface of channel 4 and 5 are under the PATA controller
3) All six channels are configured as SATA AHCI mode.

PCI Bridge
SB710 PCI Bridge supports 5 PCI slots by default but can be optionally configured to support a 6th slot.
The PCI bridge runs at 33 MHz and can support CLKRUN# function with individual clock override (option
not to stop specific PCICLK). In addition, it has the capability to hide individual PCI device.
SB710 has a strapping option for loading the boot codes from the PCI bus on the very first boot (1st boot
after RSMRST#). Subsequent boots will revert back to the ROM selection determined by the ROM straps
or PMIO programming. This is to allow system manufacturers to populate the motherboard with a blank
flash device (for BIOS) and use this option to program it. This is particularly useful for systems built
without a socket for the BIOS ROM.
8.9
High Definition Audio
Intel® High Definition (HD) Audio is the next-generation PC audio technology intended for replacing the
AC ’97. The primary goal for developing HD Audio is to create a uniform programming interface and to
provide capabilities beyond those supported by the AC ‘97. It is not intended to be backward compatible
with the AC ’97. The link protocols and operations of these two standards are not compatible, which
means AC ‘97 and HD Audio codecs cannot be mixed on the same link.
8.9.1 HD Audio Codec Connections
Figure 8-8 below shows the HD Audio interface connections to the HD Audio codecs. SB710 can support
up to 4 HD Audio codecs. Each codec will have its own AZ_SDIN (data input) for the HD Audio interface.
Figure 8-8 shows the connection of a 2 codec configuration.

Power management/ACPI
SB710 Power management/ACPI logic is identical to that of the SB600. It supports C3/C1e and stutter
mode and S states for F series and prior versions of CPUs. With the newer CPUs and RS78x series NB,
C and P states are controlled by the CPU and NB. Under this configuration, SB710 becomes a client and
uses ALLOW_LDTSTP as a handshake with NB to help NB to manage the C and P states accordingly.

RTC battery life is calculated using the rated capacity of the battery and typical current numbers. The
typical batteries used for RTC are normally rated for 170 mAh and the worst case current consumption for
the SB710 is 4.0 µA. Thus, the life of battery will be calculated as follows:
170,000 µAh / 4 µA = 42,500 h = 4.8 years

Pressure Specification
To avoid damages to the ASIC (die or solder ball joint cracks) caused by improper mechanical assembly
of the cooling device, follow the recommendations below:
ƒ
It is recommended that the maximum load that is evenly applied across the contact area between the
thermal management device and the die does not exceed 6 lbf. Note that a total load of 4-6 lbf is
adequate to secure the thermal management device and achieve the lowest thermal contact
resistance with a temperature drop across the thermal interface material of no more than 3°C. Also,
the surface flatness of the metal spreader should be 0.001 inch/1 inch.
ƒ
Pre-test the assembly fixture with a strain gauge to make sure that the flexing of the final assembled
board and the pressure applying around the ASIC package will not exceed 600 micron strain under
any circumstances.
ƒ
Ensure that any distortion (bow or twist) of the board after SMT and cooling device assembly is within
industry guidelines (IPC/EIA J-STD-001). For measurement method, refer to the industry approved
technique described in the manual IPC-TM-650, section 2.4.22.
13 Thermal Information
This section describes some key thermal parameters of the SB710. For a detailed discussion on
these parameters and other thermal design descriptions including package level thermal data and
analysis, please consult the Thermal Design and Analysis Guidelines for SB700/SB710/SB750.

Note
Notes:
1 - The maximum operating case temperature is the die geometric top-center temperature measured through proper
thermal contact to the back side of the die based on the methodology given in the document Thermal Design and
Analysis Guidelines for SB700/SB710/SB750 (Chapter 11). This is the temperature at which the functionality of the
chip is qualified.
2 - The maximum absolute rated junction temperature is the junction temperature at which the device can operate
without causing damage to the ASIC.
3 - The ambient temperature is defined as the temperature of the local intake air to the thermal management device.
The maximum ambient temperature is dependent on the heat sink's local ambient conditions as well as the chassis'
external ambient, and the value given here is based on AMD’s reference desktop heat sink solution for the SB710.
Refer to Chapter 5 in the Thermal Design and Analysis Guidelines for SB700/SB710/SB750 for heat sink and thermal
design guidelines. Refer to Chapter 6 of the above mentioned document for details of ambient conditions.
4 - Thermal Design Power (TDP) is defined as the highest power dissipated while running currently available worst
case applications at nominal voltages. The core voltage was raised to 5% above its nominal value for measuring the
ASIC power. Since the core power of modern ASICs using 65nm and smaller process technology can vary
significantly, parts specifically screened for higher core power were used for TDP measurement. The TDP is intended
only as a design reference, and the value given here is preliminary.

When TEST2 is low, a low on TEST1 will reset all test logic and allow TEST0 to choose between normal
operation and the reserved debug mode. A high on TEST1 should be followed by a bit sequence on
TEST0 to define the test mode into which the SB710 will enter. A new test mode can be entered when a
new bit sequence is transmitted. In addition to resetting the test controller asynchronously with TEST1, a
bit sequence can also be used to synchronously change the test mode. Table 14-3 shows the legal bit
sequences for TEST0. Note: Once the Test mode or Test mode and sub test mode is entered, Test2 and
Test1 should be kept at 0, 1 respectively until the requirement for the Test Mode is completed.

XOR Test Mode
Figure 14-1 illustrates the data timing for the test signals with respect to the OSC clock. Any timing
reference referred in this section is assumed to be based on OSC clock running at 25 MHz. The OSC
clock can be slowed down to 1 MHz as long as the bit stream applied on TEST0 pin is also in sync with
this clock. The 25-MHz OSC clock should be disconnected first. For setting any Test 0 bit sequence, the
OSC clock is required only up-to the time the mode set is completed. After this the clock can be stopped

and as long as TEST1 and Test2 pins are set to {1, 0} respectively to maintain the selected mode to be
active. Note that once TEST1 is set to one, TEST0 needs to be asserted to one for at least 8 clocks
before transmitting the test mode bit sequence. The rising of “Internal Test Mode” in the diagram indicates
the time when the SB710 enters into test mode.

Figure 14-2: A Generic XOR Chain
Pin A is assigned to the output direction, and pins B through F are assigned to the input direction.
It can be seen that after all pins from B to F are assigned to logic 0 or 1, a logic change in any
one of these pins will toggle the output pin A.
The following is the truth table for the XOR Chain shown in Figure 14-2. The XOR start signal is
assumed to be logic 1.This is an internal signal to the ASIC and is not part of the XOR tree pins
listed in Table 14-5.
Once the inputs are set to the respective value the output pin will reflect the correct value within
200 ns. Note: OSC clock is not required to be running after the mode is already set and the pads
are exercised in XOR Tree function.

14.2.2 Description of the SB710 XOR Chain
During XOR Chain Test Mode, most of the chip pads on the SB710 are connected together using
XOR gates as shown in Figure 14-3. The first input of the chain is connected to a logic level high
(internal connection), and all pads (listed in Table 14-5) are configured as inputs except for the
last pad in the chain, which is configured as an output. KBRST#/GEVENT1# is the start of the chain
and SERIRQ is the end of the chain. Table 14-5 lists all pads that are on the SB710 XOR chain,
as well as and their order of connection. Pads are chained together in the shown order, i.e., pad
number 1 is the first pad on the XOR chain, pad number 2 the second, and so on.

14.2.2.1 Unused Pins
The pins that are part of the XOR chain (see Table 14-5) but are not used for testing must be pulled-up or
down before the XOR chain is activated. No pins in the XOR chain should be left floating. All digital or
analog pins not included in Table 14-5 are not part of the XOR chain and can be left floating during an
XOR test. That includes the output of the XOR chain, FANOUT0/GPIO3, and other pads shown in Table
14-6 below.
