Hardware Specifications
The innovative Coherency Fabric architecture provides a
coherent interconnect between the CPUs themselves
and between the CPUs and the I/O masters. This
enables the system to operate either in Symmetrical
Multi Processing (SMP) mode or Asymmetric Multi
Processing (AMP) mode, with I/O cache coherency. In
addition, the efficiency of the bus enables a
high-frequency, high-bandwidth, and low-latency access
time throughout the CPU memory subsystem.
The on-chip Mbus architecture, a Marvell® proprietary
crossbar interconnect for non-blocking any-to-any
connectivity, enables concurrent transactions among
multiple units. This design results in high system
throughput, allowing system designers to create
high-performance products.
The pin and software compatibility with the other
ARMADA XP devices, offers full performance scalability
to best fit the requirements of any specific applications.

Typical Applications and System Configurations
Main CPU in a Control Plane
1
Typical Applications and System
Configurations
The MV78260 can be used in a variety of applications. Examples of these applications are provided
in the following sections.
1.1
Main CPU in a Control Plane
The ARMADA® XP Highly Integrated Multi-Core ARMv7 Based System-on-Chip Processors SoC
combined with a Marvell® high-performance core processor CPU is an ideal choice for networking
control planes and switch management applications.
The ultra high-speed and bandwidth supported DRAM and the large L2 cache allow the MV78260 to
perfectly match the high-demand computing power of a control plane application. With the full
scalability from single core to quad core using an MV78260 or MV78460 device, it is possible to run
the cores in SMP mode and gain more computing power than in single CPU mode.
As the main CPU on the plane, the MV78260 is connected via an Ethernet switch to all of the other
line cards on the plane for management tasks. The switch may also be connected to the backplane
for handling packets that were not processed by the data plane, due to a lack of information or
exceptions that occur.
To backup the line cards Ethernet link from failures, the line cards can be connected in a secondary
link to the MV78260 via the High-Level Data Link Control (HDLC) through the TDM interface. If the
Ethernet link fails, the HDLC is used to keep the management routines running until the link is
restored.
The other Ethernet ports of the MV78260 may be used to connect to a mirror card, a debug port, or
as a high-speed management access port for a remote host.
The multiple PCI Express (PCIe) ports provide flexibility to connect to network I/O modules and
cards. The PCIe port can be configured as one lane of x4, or four lanes of x1, to enable up to eight
different card connections, or up to three x4 lanes for increased bandwidth or a combination of
lanes.
The integrated USB controller and PHY enables a convenient interface for software code upgrades,
while the diverse flash interfaces (NOR, NAND, and SPI) allow the system designer the option to
choose the best boot option to fit the application needs and minimize the BOM cost.

1.2
NVR/DVR/Hybrid Video Surveillance Application
Video surveillance applications, Network Video Recorders (NVR), and Digital Video
Recorders (DVR) can also take advantage of the MV78260 SoC.
The high-integration of the MV78260 that resides within the NVR box, with the high-performance
core processor CPU, drives H.264 or MPEG-2 data streams from multiple camera banks that are
connected over the GbE ports to various I/Os. These I/Os include storage (disks over PCIe or SATA
interfaces) or remote host monitoring (over Ethernet interface). The TCP acceleration features
offered by the device, and the ability to balance the work load on the CPUs handling the incoming
TCP streams, enables the platform to support dozens of the high definition IP cameras.
High-performance writes and reads to mass storage are an essential centerpiece for these
applications, and the device offers outstanding performance in this arena.
There are several storage expansion options with the two PCIe ports, offering five to eight
high-speed, 5 Gbps PCIe lanes, and enabling connectivity to mass storage or DSP banks to
interface analog cameras. The fluent PCIe-to-Memory and Memory-to-PCIe operations of the
MV78260, the effective disk access, and the core processor CPU capability to successfully handle
the high frame rate and resolution from a large number of sources, enables the device to support the
application’s target number of analog cameras.
The three USB ports with integrated PHYs, the SATA ports that can be used for eSATA extensions or
a DVD write backup interface, with the LCD interface that can be used for a local view via VGA, and
the integrated clock generation and security engine offer a complete SoC integrated solution at low
power to make this SoC the ideal choice for such applications.

Enterprise Laser Printer Application
The MV78260 I/O integration, low power, strong core processor CPUs, and an on-chip Floating
Point Unit (FPU) makes the device an ideal solution for high-performance enterprise printer
applications. The device integrates several I/O peripherals that result in a smaller, simpler board
design with lower manufacturing cost.
The device’s advanced power save modes enable a power-saving, environmentally friendly, green
printer design that meets the restrictive power consumption requirements of worldwide energy
regulations, such as Energy Star, EuP, and Top Runners.
In addition to system level power save modes such as DRAM power save modes, Energy Efficient
Ethernet, PCIe, and USB power save modes, the MV78260 offers chip level power save options that
include power down modes, standby modes, clock throttling modes.
To complete this device’s efficient operation, it offers diverse waking options from power save
modes, such as:
Diversified Wake On LAN (WOL) options
Wake On USB
Wake On GPIO

Hardware Specifications
It also guarantees zero packet loss during the wake-up period until the CPU is powered up and
ready to process the incoming packets.
The multiple PCIe lanes allow printer designers to connect imaging ASICs to the x4 PCIe interfaces,
and use the x1 configurations for other PCIe peripherals. The three on-chip USB ports can connect
to PCs, scanners, fax machines, USB flash drives, or wireless connectivity devices. The integrated
SATA interface eliminates the need for an external SATA controller for the printer’s spooling hard
drive.
The integrated LCD controller is capable of supporting up to 24 bpp, with high resolution. It can be
used to interface with the printer’s LCD panel. The integrated SPI controller provides the option to
interface with an LCD screen, if it is used as a touch screen. As in most printers, the LCD panel is
located relatively far from the CPU, the device provides LVDS transmitters for the clock and data to
connect between the device’s LCD logic and the remote LCD panel.

MV78260 in Dense Computing and Blade Server
Applications
The ever increasing requirement for computing power and availability in data centers is pushing the
server performance requirements to a peak. Along with that comes the increase in size, cost, power
and complexity of the data center. In fact, one of the major challenges for such applications today is
the sharp increase in power consumption and as a result the sharp increase in cooling costs and in
the complexity of the cooling infrastructure. This complexity also implies for less dense blades,
which translates into less powerful racks.
As a result, blade designs are more performance/Watt oriented rather than just raw performance
oriented.
The MV78260 maximizes the performance/Watt equation to a best in class level. The strong Marvell

Typical Applications and System Configurations
MV78260 in Dense Computing and Blade Server Applications
cache and a fast and effective DRAM memory running at a data rate of 1600Mbps/pin (DDR3-1600),
provides the needed infrastructure for a powerful computing machine to address the high
requirements of the data center.
The ultra low power consumption of the device, removes the need for complex and expensive
cooling elements, and keep the overall power consumption of the blade at a minimum.
The device peripherals provide all the needed connectivity to the blade’s interfaces. The highbandwidth PCIe ports may be used as connectivity ports towards the storage ranks, while the SGMII
and DRSGMII (SGMII at 2.5 Gbps) can be connected to the backplane. A local disk may be
connected to the MV78260 via the SATA port.
Figure 4 shows the MV78260 in a typical blade server application.

Clock Frequency Configuration Options
The PCLK0-to-NBCLK ratios, NBCLK-to-HCLK ratios, and HCLK-to-DRAMCLK ratios are
determined via reset strapping. Table 30 summarizes the possible frequencies of the various
domains as a function of the selected CPU speed.
Note

To set up target clock frequencies, first select the target CPU speed via CPU0
Clock Frequency Select in Table 36, Reset Configuration Pins, on page 84 reset
straps, and then configure the Fabric Frequency Options reset straps to the
specified index according to Table 30.
The PCLK0 frequency specifies the target frequency of CPU0. The other CPU core
default clock frequency is set to the selected NBCLK frequency. As part of the
CPU0 boot flow, and in case a different speed target is required for the other core,
the software needs to reconfigure the target frequencies for the other core through
the software.
PCLK0 frequency must always be greater or equal to PCLK<n>.

Table 30 lists the various frequency options and the supported CPU0 speeds that may be configured
via the <CPU0 Clock Frequency Select> field in Non-Core and Core Voltages (Table 35 p. 87) reset

REFCLK_OUT: Stable 25 MHz output clock from the device. Can be used as reference input
clock for other components on the board.
PCIe_CLKREQ0, PCIe_CLKREQ1: When the port is configured as RC, endpoints may drive
the clock request to high. This causes the PCI clock request to be gated. During normal
operations, the clock request should be driven low, which means the PCI clock is not held. For
further information, see the PCI Express section in the device’s Functional Specifications.

Multi Purpose Pins Power Segments
The different power segments for each of the MPP pins is listed in the Power Pins Description table
in Table 26, Power Supply Pins, on page 59.
The voltage level of VDDO_C and VDDO_DEV is determined by a reset strap. The voltage level of
VDDO_A and VDDO_B is 3.3V by default, with a register configurable option to 1.8/2.5V or 2.5V.
Refer to the System Considerations section in the ARMADA® XP Highly Integrated Multi-Core
ARMv7 Based System-on-Chip Processors Functional Specifications for more information about
voltage setting.
6.3
Multi Purpose Pins Functional Considerations
When configuring MPP pins note the following issues, also refer to the attached Multi Purpose Pin
Functional Summary Table:
For MPPs assigned as NOR or SPI flash, the wake-up mode after reset depends on the Boot
mode (see the Boot Device Type Selection field in Table 36, Reset Configuration Pins, on
page 84).
There are a few options for the boot device as listed in Table 36. The value set in field Boot
Device Type Selection determines the type of the boot select during reset. The values set in
Table 36 effect the default value of <MPPSel> fields in the MPP Control registers.
• If Boot Device Type Selection is set to 0x0 (boot from a NOR flash) and the Boot Device
Width is set to 0x0 (32-bit bus interface), MPP[66:49] pins wake up as Device Bus signals.
• If Boot Device Type Selection is set to 0x3, MPP[39:36] pins wake up as SPI flash signals.

Pin Multiplexing
Gigabit Ethernet Pins Multiplexing on the MPP
6.4
UART0, UART1, UART2, and UART3 signals are duplicated on some MPP pins. The UART0,
UART1, UART2, or UART3 signals must not be configured to more than one MPP option.
All other MPP interface pins wake up after reset in 0x0 mode (GPIO). By default, these pins are
set to Data Output disabled (Tri-State). Therefore, these MPPs are in fact inputs.
Some of the MPP pins are sampled during SYSRSTn de-assertion to set the device
configuration. These pins must be driven to the correct value during reset (see Table 36, Reset
Configuration Pins, on page 84).
Pins that are left as GPIO and are not connected must be configured as outputs via the GPIO
registers after SYSRSTn de-assertion (see General Purpose I/O section in the ARMADA® XP
Highly Integrated Multi-Core ARMv7 Based System-on-Chip Processors Functional
Specifications).
Gigabit Ethernet Pins Multiplexing on the MPP
There are two Gigabit Ethernet ports that are multiplexed on the MPP pins.
Each of these Gigabit Ethernet ports can operate in RGMII mode.
Port 0 also supports GMII/MII signaling.
The device also contains a SERDES interface that can be used as SGMII interfaces for port 0, 1, 2,
and 3. Once a port is configured as an SGMII port, it cannot be selected as an RGMII/GMII/MII port
on the MPP pins. The SGMII interface may be selected on various SERDES options (see
Section 6.7, High-Speed SERDES Multiplexing, on page 76. Do not select more than one SERDES
option for the same GbE port.
Table 31 lists the Gigabit Ethernet multiplexing pin configuration options for Port0 and Port1, when
the port is not used as SGMII.

6.5
When using GbE signals on MPPs, all relevant GbE signals (except those marked
as N/A) must be implemented. For example, if using MII, and the chosen PHY does not
have an MII_RXERR out signal, the GE0_RXERR on the MPP pin must still be
configured accordingly and must have a pull-down resistor.
LCD Pin Multiplexing on the MPP
The LCD interface is multiplexed on MPP[28:0] (see Table 32). Not all LCD panels require the full
29 pins. Any pins that are not used as LCD pins, may be used for different pin assignment according
to the options shown in the attached Excel file (see Section 6.1, Multi Purpose Pins Functional
Summary, on page 69). The supported LCD interface modes are listed in Table 32.

When a touch panel SPI interface is required, use one of the available SPI interface
configuration options on the MPP pins. The SPI interface may be configured through
MPP[47:36].
Serialized LVDS Transmitter
The integrated serialized LVDS transmitter supports the following features at up to 65 MSPS:
18-bit or 24-bit per pixel (three or four transmit differential data/control lanes)
Transmit differential clock lane (driven by the LCD_CLK output)
Two data serialization options in 24-bit per pixel mode
Option to disable serialization and force constant zero output in data/control lanes
Configurable tick delay on data/control lanes relative to clock lane
Option to disable the fast reference clock when LVDS is not in use
Option to power down LVDS pads when not in use
The LVDS and parallel RGB interface are usually not used together. When LVDS is not used,
Marvell recommends powering down the pads and disabling serialization for power saving.
Figure 6 displays the connectivity between the LCD unit and the LVDS.

7.1
Power Up/Down Sequence
7.1.1
Power-Up Sequence
These requirements must be applied to meet the device power-up sequence (see Figure 7):
The Non-Core voltages (I/O and Analog), as listed in Table 35, must reach 70% of their voltage
level before the Core voltages.
The order of the power up sequence between the Non-Core voltages is unimportant. The order
of the power up sequence between the Core voltages is unimportant either.
The reset signal(s) must be asserted before the Core voltages reach 70% of their voltage level.
Each reference clock input must toggle with its respective voltage level before the first Core
voltage reaches 70% of their voltage level. If a crystal oscillator is used, the system can rely on
the oscillator wake-up mechanism.

Note
7.1.2
It is the designer's responsibility to verify that the power sequencing requirements
of other components are also met.
Although the Non-Core voltages can be powered up any time before the Core
voltages, allow a reasonable time limit (for example 100 ms) between the first
Non-Core voltage power-up and the last Core voltage power-up.
Power-Down Sequence
Allow a reasonable time limit (for example 100 ms) between the first and last voltage power-down.
7.2
Hardware Reset
The device has three reset inputs pin: SYSRSTn, CDRn, MRn. The following sections describe the
functionality of these signals.
7.2.1
Global System Reset (SYSRSTn)
When asserted, the entire chip is placed in its initial state. Most outputs are placed in high-Z.
The following output pins are still active during SYSRSTn assertion:
M_CLKOUT[3:0], M_CLKOUTn[3:0]

Reset and Initialization
Hardware Reset
PEX<n>_CLK_N
PEX<n>_CLK_P
The device has an optional SYSRST_OUTn open drain output signal, that is used as a reset request
from the device to the board reset logic. This signal is set when one of the following maskable events
occurs. In each of these cases, SYSRST_OUTn is asserted for a duration of 100 ms:
Received a hot reset indication from the PCI Express port 0 link when used as a PCI Express
endpoint, and bit <PCIe0RstOutMaskSysRstOut> is cleared to 0, and <GlobalSoftRstOutEn> is
set to 1 in the RSTOUTn Mask Register (offset 0x00018260) (see the System Registers
appendix of the device’s Functional Specifications).
PCI Express port 0 link failure, when used as a PCI Express endpoint, and bit
<PCIe0RstOutMaskSysRstOut> is cleared to 0, and <GlobalSoftRstOutEn> is set to 1 in the
RSTOUTn Mask Register (see the System Registers appendix of the device’s Functional
Specifications).
One of the Watchdog timers expires and bit <WDRstOutEn> of the relevant watchdog counter is
set to 1 in the RSTOUTn Mask Register (see the System Registers appendix of the device’s
Functional Specifications).
Bit <SystemSoftRst> is set to 1 in System Soft Reset Register (offset 0x00018264) and bit
<SoftRstOutEn> is set to 1 in RSTOUTn Mask Register (offset 0x00018260) (see the System
Registers appendix of the device’s Functional Specifications).
An assertion of the internal power-on-reset (POR) circuit (see Section 7.4, Power On Reset
(POR), on page 83 for further details). This assertion is not maskable. The duration of this
assertion is for at least 100ms.
SYSRST_OUTn is asserted as long as the MRn input signal is asserted low, and for an
additional at least 100 ms after MRn de-assertion (This is useful for implementations that
include a manual reset button).
Note
7.2.1.1
SYSRSTn must be active for a minimum length of 20 ms. Core power, I/O power, and
analog power must be stable (VDD +/- 5%) during that time and onward.
SYSRSTn Duration Counter
When SYSRSTn is asserted low, a SYSRSTn duration counter starts counting. It continues to count
as long as the SYSRSTn signal remains asserted.
The counter clock is the 25 MHz reference clock.
It is a 29-bit counter, yielding a maximum counting duration of 2^29/25 MHz (21.4 seconds).
The host software can read the counter value and reset the counter.
When the counter reaches its maximum value, it remains at this value until the counter reset is
triggered by software.
See the device’s Functional Specifications for details on how to configure the SYSRSTn duration
counter.
Note
The SYSRSTn duration counter is useful for implementing manufacturer/factory reset.
Upon a long reset assertion, greater than a pre-configured threshold, the host software
may reset all settings to the factory default values.

Hardware Specifications
7.2.2
Manual Reset (MRn)
The Manual Reset pin (MRn) provide the user the ability to reset the device without powering down
the device. This is useful for implementations that include a reset button. Once MRn pin is asserted
low, the device’s reset logic, that includes a bouncer circuit to avoid false reset spikes, will propagate
a reset indication to the SYSRST_OUTn pin. The SYSRST_OUTn will be asserted as long as the
MRn pin is kept asserted and for additional 100ms. The external (on board) logic may drive this
indication back to the SYSRSTn pin to reset the device, and in addition use the SYSRST_OUTn pin
to reset the entire board.
7.2.3
Marvell® Core Processor CPU Debugger Reset
Connect the CPU debugger reset to the CDRn pin.
When the CPU Debugger reset is asserted, the device returns to its default value. The device
mechanisms related to the debugger are excluded from the reset event. This includes the PLLs, the
SSCG, the XTAL, and the registers controlling those mechanisms.
In general, the CDRn is de-asserted after all processes on the TAP controller are completed (refer to
the specific Debugger specifications).
CPU debugger reset should be fed into two separate circuits:
The device’s CDRn pin (the reset pin for the debugger).
The board reset for all other devices (not including the device’s SYSRSTn pin), since
SYSRST_OUTn will not be forced by the CDR pin.
7.3
PCI Express Reset
As a Root Complex, the device can generate a Hot Reset to the PCI Express port. Upon CPU
setting of the PCI Express Control register’s <ConMstrHot Reset> bit, the PCI Express unit sends a
Hot Reset indication to the Endpoint (see the PCI Express Interface section in the device’s
Functional Specifications).
When the device works as an Endpoint, and a Hot Reset packet is received:
A maskable interrupt is asserted.
If the PCI Express Debug Control register’s <DisHotResetRegRst> is cleared, the device also
resets the PCI Express register file to its default values.
The device triggers an internal reset, if not masked by PCI Express Debug Control register’s
<ConfMskHotReset> bit.
Link failure is detected if the PCI Express link was up (LTTSSM L0 state) and dropped back to an
inactive state (LTSSM Detect state). When Link failure is detected:
A maskable interrupt is asserted
If the PCI Express Debug Control register’s <DisLinkFailRegRst> is cleared, the device also
resets the PCI Express register file to its default values.
The device triggers an internal reset, if not masked by PCI Express Debug Control register’s
<ConfMskLinkFail> bit.
Whether initiated by a hot reset or link failure, this internal reset indication can be routed to the
PCIe_RSTOUTn signal (multiplexed on MPP[43]) to reset components on the board without
resetting the entire device (e.g reset only the endpoint card).
Note
Only the PCIe0 port (or PCIe0.0 port in Quad x1 configuration) can act as a PCI
Express endpoint, and only this port can generate the PCI Express internal reset
indication.

Reset and Initialization
Power On Reset (POR)
7.4
Power On Reset (POR)
The device integrates a Power On Reset (POR) circuit. The circuit is triggered when the VDD (digital
core voltage) and VDD_CPU (CPU core Voltage) power up levels reach a VDD threshold (with a
threshold maximum value of 0.8V).
Hysteresis: Another trigger will only occur after any of the power first drops to 50 mV, and then a
power up occurs.
Once the POR logic was triggered the SYSRST_OUTn output signal is asserted low for 100 ms.
The SYSRST_OUTn signal may be connected externally to the device’s SYSRSTn input signal
asserting the device’s internal reset signal. In addition, the SYSRST_OUTn signal may be used in
this case as the POR generator for the entire board.
7.5
Reset Configuration
The device uses certain pins as configuration inputs to set certain critical parameters following a
reset. The definition of the sampled at reset configuration pins revert immediately after reset to their
regular function.
7.5.1
Pin Sampling Configuration
The following pins are sampled during SYSRSTn de-assertion. Some of the device’s pins integrate
an internal pull-up/pull-down resistors to set a default mode. Smaller external pull-up/pull-down
resistors are required to change the default mode of operation, if required. These signals must
remain pulled up or down until SYSRSTn de-assertion (zero Hold time in respect to SYSRSTn
de-assertion).
Note
If external logic is used instead of pull-up and pull-down resistors, the logic must
drive all of these signals to the desired values during SYSRSTn assertion. To
prevent bus contention on these pins, the external logic must float the bus no later
than the third TCLK cycle after SYSRSTn de-assertion.
All reset sampled values are registered in the Sample at Reset register (see the
MPP Registers in the device’s Functional Specifications). This is useful for board
debug purposes and identification of board and system settings for the host
software.
If a signal is pulled up on the board for reset sampling, it must be pulled to the
appropriate voltage level of the power domain that the signal is assigned to. For
example, if MPP[X] should be pulled up for reset sampling, it should be pulled to
the voltage level of the VDDO who is feeding MPP[X] according to the pin
description table.
If an external device is driving any of the pins that are used as sampled at reset
signals, make sure to keep this external device in reset state (prevent it from
driving) or use glue logic to disconnect it from the device as long as the device
SYSRSTn input is asserted.

Serial ROM Initialization
The device supports initialization of ALL of its internal and configuration registers through the I2C0
master interface. If serial ROM initialization is enabled by pulling up I2C0 Serial ROM Initialization
during SYSRSTn assertion, the device I2C0 master starts reading initialization data from serial ROM
and writes it to the appropriate registers.
7.6.1
Serial ROM Data Structure
The Serial ROM data structure consists of a sequence of 32-bit address and 32-bit data pairs, as
shown in Figure 8.

The serial ROM initialization logic reads eight bytes at a time. It performs address decoding on the
32-bit address being read, and based on address decoding result, writes the next four bytes to the
required target.
The Serial Initialization Last Data Register contains the expected value of last serial data item
(default value is 0xFFFFFFFF). When the device reaches last data, it stops the initialization
sequence.
Note
7.6.2
Users must not generate requests through the I2C0 auto-loader to addresses that are
not 32-bit aligned.
Serial ROM Initialization Operation
On SYSRSTn de-assertion, the device starts the initialization process. It first performs a dummy
write access to the serial ROM, with data byte(s) of 0x0, to set the ROM byte offset to 0x0. Then, it
performs a sequence of reads, until it reaches last data item, as shown in Figure 9.

Implementation Notes:
Initialization data must be programmed in the serial ROM starting at offset 0x0.
The serial EEPROM must contain two address offset bytes (16-bits). These bytes must not be
less than a 256 byte ROM.
The device assumes 7-bit serial ROM address of ‘b1010000.
After receiving the last data identifier (default value is 0xFFFFFFFF), the device receives an
additional byte of dummy data. It responds with no-ack, and then asserts the stop bit.
For a detailed description of I2C implementation, see the I2C Interface section in the device’s
Functional Specifications.
7.7
Boot Sequence
The device requires that SYSRSTn stay asserted for at least 100 ms after power and clocks are
stable. The following procedure describes the boot sequence starting with SYSRSTn assertion:
1. While SYSRSTn is asserted, the CPU PLL and the core PLL are locked.
2. Upon SYSRSTn de-assertion, the pad drive auto-calibration process starts and the DRAM PHY
DLL starts to lock on the target frequency speed. It requires 3ms to gain lock indication and be
ready for normal operation.
3. If Serial ROM initialization is enabled, an initialization sequence is started.
Upon completing the above sequence, the internal CPU reset is de-asserted, and the CPU starts
executing boot code from the internal Boot ROM, according to sample at reset setting of Boot
Device Type Selection.
For boot sequence details, see the BootROM Firmware section in the device’s Functional
Specifications.
As part of the CPU boot code, the CPU typically performs these steps:
1. Configures the PCI Express address map.
2. Configure device bus timing parameters, according to devices attached to device bus.
3. Configures the proper SDRAM controller parameters, and then triggers SDRAM initialization.
4. Sets <InitEn> bit [0] to 1 in the SDRAM Initialization Control register. Initializes proper ECC to
the entire SDRAM space.
5. Sets the <PEXxEn> bits in the SoC Control register to wake up the PCI Express link.

Instruction Register
The Instruction register (IR) is a 4-bit, two-stage register. It contains the command that is shifted in
when the DAP FSM is in the Shift-IR state. When the DAP FSM is in the Capture-IR state, the IR
outputs all four bits in parallel.

register value.
BYPASS
11111
Selects the single bit Bypass register between TDI and TDO. This allows
for rapid data movement through an untested device.
Bypass Register
The Bypass register (BR) is a single bit serial shift register that connects TDI to TDO, when the IR
holds the Bypass command, and the DAP FSM is in Shift-DR state. Data that is driven on the TDI
input pin is shifted out one cycle later on the TDO output pin. The Bypass register is loaded with 0
when the DAP FSM is in the Capture-DR state.
8.3
JTAG Scan Chain
The JTAG Scan Chain is a serial shift register used to sample and drive all of the device pins during
the JTAG tests. It is a 2-bit per pin shift register in the device, thereby allowing the shift register to
sequentially access all of the data pins both for driving and strobing data. For further details, refer to
the BSDL Description file for the device.
8.4
ID Register
The ID register is a 32-bit deep serial shift register. The ID register is loaded with vendor and device
information when the DAP FSM is in the Capture-DR state. The Identification code format of the ID
register is shown in Table 38, which describes the various ID Code fields.

SoC Power Dissipation for Power Management Unit
Low Power Modes
The MV78260 Power Management Unit (PMU) controls power management functions and enables
the optimization of the device’s overall power consumption and performance.
The PMU allows for Idle, Deep Idle, and Sleep low power modes that supply different levels of power
consumption, with hardware controlling wake-up events and power mode transitions.
Table 43 lists the MV78260 power dissipation for specific SoC configurations, and not the total
power of the device.
The following system configuration were used for testing:
Dual core CPU @ 1600 MHz
DDR 64-bit (ECC and dual CS), 1.5V @ 800 MHz
1 SGMII SERDES
2 x PCIe x1
1 SATA
1 USB
SPI
Note
For more details on the MV78260 power modes and additional PMU features, refer
to the Power Management Unit section of the MV78260 Functional Specifications.
To calculate the overall power for any other SoC configuration, use the power
values in Table 41 on page 97 and Table 42.

Slew rate is defined from 20% to 80% of the reference clock signal.
This value is required when using the internal PLL to drive the SERDES.
The REFCLK_OUT duty cycle/jitter is driven by the REF_CLK_XIN duty cycle/jitter. There is a
5% degradation of the output duty cycle. There is a 50 ps degradation of the output jitter.
The load is CL = 15 pF.
This value is assumed to contain above 95% random components characterized by 1/f
behavior, defined with a BER = 1e-12.
It is possible to use this reference clock when working in source synchronous device bus mode.
For additional information regarding configuring this clock, see the Inter-Integrated Circuit
Registers in the device’s Functional Specification.
For additional information regarding configuring this clock, see the SPI Interface Configuration
Register in the device’s Functional Specification.
The RTC design was optimized for a standard CL = 12.5 pF crystal. No passive components
are provided internally. Connect the crystal and the passive network as recommended by the
crystal manufacturer.

routing clocks so that an additional trace delay of greater than 1.5 ns and less
than 2.0 ns is added to the associated clock signal.
For 10/100 Mbps RGMII, the Max value is unspecified.
1. For RGMII at 10 Mbps and 100 Mbps, Tcyc w ill scale to 400 ns +/-40 ns and 40 ns +/-4 ns, respectively.
2. For all signals, the load is CL = 5 pF.

The allow ed random jitter equals the allow ed total jitter minus the actual deterministic jitter
and duty cycle distortion at that point.
7. The interconnect insertion loss specification is defined from the TX pins (w ith zero pre-emphasis) to the RX pins.
The interconnect value betw een the frequencies should be extrapolated using
linear extrapolation on a logarithmic loss scale.
8. The interconnect definition w as determined to allow a maximum insertion loss value at
a frequency equal to half the bit rate.
The insertion loss value must vary w ithout notch-like behavior up to a maximum frequency
as defined by the interconnect definition.
9. Vidpps refers to the internal eye opening w hile Vidpp refers to the peak-to-peak.
10. Jitter distribution w here the value of the jitter show s no correlation to any signal level being transmitted.
11. Jitter distribution w here the value of the jitter show s a strong correlation to the signal level being transmitted.
This jitter may be considered as being equalizable due to its correlation to the signal level (ISI).
12. This is the sum of Jtrxuc and Jtrxisi.
13. The clock for output TX jitter is generated using a golden PLL.
