Functional Description
4.2 Processor
The COMX-P4080 COM Express Module is based on the Freescale Power PC COMX-P4080
platform and supports the Qor1Q COMX-P4080 integrated processor. It can run at the speed
of 1.5 GHz and is compatible with the P30 and P50 series. The QorIQ COMX-P4080 integrated
communication processor combines eight Power Architecture TM processor cores that allow
high performance data path acceleration, logic and network, as well as peripheral bus
interfaces required for networking, telecom/datacom, wireless infrastructure and
military/aerospace applications.
Figure 4-2 COMX-P4080 Processor Block Diagram
4.3 Memory
The COMX-P4080 COM Express Module supports up to 2-GB dual-rank DDR3 1066 MHz/1333
MHz ECC SO-UDIMM memory modules arranged in two ranks in one slot.
56
COMX-P4080 COM Express Module Installation and Use (6806800L20C)
There are two 204-pin SO-UDIMM slots on the module measuring 5.2 mm high and 9.2 mm
high, respectively. Both are placed on the same side of the PCB in consideration of thermal
issues.
4.4 Power Supply
Power is supplied to the COMX-P4080 module from an ATX-type power supply through the
COM-E connectors. On-board regulators supply the required voltages to devices attached to
the module.

57
Functional Description
The power sequencing of the COMX-P4080 is different for the secure boot mode and the nonsecure boot mode. For the secure boot mode, POVDD should be tied to 1.5 V DC and is
powered at least 100 system clock cycles after the rising edge of power on reset signal. For
non-secure boot mode, POVDD should be tied to GND. The following figure illustrates this
process.
Figure 4-4 COMX-P4080 Power Sequencing

COMX-P4080 COM Express Module Installation and Use (6806800L20C)
4.5 Clock Distribution
The COMX-P4080 needs several kinds of single-ended and different clocks for booting up and
normal operation. The clock distribution list is illustrated below.
Figure 4-5 COMX-P4080 Clock Distribution
Functional Description
The frequency of the three SerDes banks’ reference clocks can be set from 100 MHz to 125
MHz using the S1 switch.
Table 4-2 SerDes Clock Configuration by S1 Switch
SerDes Bank 1 Reference Clock SerDes Bank 2 Reference Clock SerDes Bank 3 Reference Clock
S1.2=ON, 125MHz S1.3=ON, 100MHz S1.4=ON, 100MHz
S1.2=OFF, 100MHz S1.3=OFF, 125MHz S1.4=OFF, 125MHz
Default:100MHz Default:125MHz Default:125MHz
COMX-P4080 COM Express Module Installation and Use (6806800L20C)
59
Functional Description
It can also be set by three GPIOs.
Table 4-3 SerDes Clock Configuration by GPIO
SerDes Bank 1 Reference Clock SerDes Bank 2 Reference Clock SerDes Bank 3 Reference Clock
CPU_GPIO23=0, 100MHz CPU_GPIO24=0, 100MHz CPU_GPIO26=0, 100MHz
CPU_GPIO23=1, 125MHz CPU_GPIO24=1, 125MHz CPU_GPIO26=1, 125MHz
Default:100MHz Default:125MHz Default:125MHz
The setting of the S1 or GPIO depends on the protocols running at the SerDes lanes that belong
to each bank. When the SerDes lanes are running at 3.125 Gbps, the corresponding bank
reference clock should be set as 125 MHz. Any speed other than 3.125 Gbps should be set to
100 MHz. For example, if the lanes in bank 1 are configured as PCI-E, then the bank 1 reference
clock should be set to 100 MHz. If it is set to XAUI, it should be at 125 MHz.
4.6 Boot Up Options
The COMX-P4080 supports several kinds of devices to load configuration information to the
Reset Configuration Word (RCW) register, as well as devices in assisting the U-Boot codes to
boot up the system. This includes NOR flash and NAND flash (both attached to the local bus),
I2C, EEPROM, SPI flash and hardware strapping. The boot option is set by an 8-bit S2 switch. For
more information, see the following table.

Functional Description
The "X" on the table indicates the "ON" or "OFF" state of the corresponding bits of the S2 switch.
Both NOR and NAND flash are attached to the local bus of the COMX-P4080. The chip select
signal (CS) of the selected RCW source should be connected to the CS0 of the local bus. When
set by the fifth bit of the S1 switch, neither the NOR or NAND flash can be selected as the RCW
without properly setting the S1.5.

In cases where all the devices fail to work, hardware strapping can be picked as an option for
loading the RCW. This is also useful for quick debugging purposes. The hard-code
configuration details are shown the table below.

4.8 LAN
The COMX-P4080 has one Gigabit port with an LED that shows the controlling signals. It is
routed to the COM-E connectors. The interface between MAC and PHY BCM5482 is the first
group of the RGMII bus and is multiplexed with ULPI bus. The RCW should then be properly set
to select the RGMII protocol.
There are two ports included in the GE PHY BCM5482, the first of which is the only one available
in the COMX-P4080 platform. Both ports are available in the P30 and P50 platforms.
The COMX-P4080 has two groups of MDIO buses. The first group is called EMI1 and compiles
with IEEE 802.3 Clause 22 standard. It has two pins, EMI1_MDC and EMI1_MDIO and is
available externally only on dTSEC0@FMan1. This group is used for the communication
between the MAC and PHY. It also manages SGMII PHY.
The second group is called EMI2 and it complies with IEEE 802.3ae Clause 45. EMI2 has two
pins: EMI2_MDC and EMI2_MDIO and is available externally only on 10GEC of FMan1. EMI2 is
used for the communication between 10GEC and PHY.
The ports in the BCM5482 has two LED controlling signals: LAN1_LINK_ACTIVITY_N and
LAN_LINKSPEED_N. The COM-E connectors have four LED controlling signals: link, activity,
link_100 and link_1000. The link and activity signals are attached to the LAN1_LINK_ACTIVITY
of the BCM5482. Link_1000 is connected to LAN1_LINKSPEED_N and link_100 is left
disconnected.

The COMX-P4080 has four USB 2.0 ports, implemented by one USB PHY (USB3315) controller
and one four-port USB hub (USB2514). Between the controller and the hub is the ULPI bus,
which is the second group of multiplexing interface in the RGMII/ULPI, making the RCW
properly set for using this group.
All four USB port signals are routed to the COM-E connectors.
The operating mode of the USB hub is configured by hardware strapping, and can be
configured by the I2C bus by changing the state of the strapping pins. Hardware strapping is
set as the default. When configured, the I2C bus address of the USB bus is 0x58.
4.10 UART
There are a total of four universal asynchronous receiver/transmitters (UART) in the COMXP4080. Each UART has Tx and RX signals that are routed to the COM-E connectors. The UART
can also be in two dual UART (DUART), with Tx, Rx, CTS, RTS signals for each DUART. Optional
resistors are also available to determine whether UART or DUART are routed.
4.11 1588
The COMX-P4080 module supports signals for the IEEE 1588-v2 capable ethernet interface to
the COM-E connector. These signals include Trigger, Alarm, Clock-In and Pulse-Out.
4.12 SDHC
The COMX-P4080 provides an SD/MMC interface to the COM-E. It needs to change the switch
S2.6 according to the card type on the carrier.

4.13 Local Bus
There is one 128-MB NOR flash and one 1-GB NAND flash attached to the local bus. The NOR
flash is used for storage of the RCW data, U-Boot and Linux kernel. By default, the NAND flash
is used for storing the file system.
Four chip select signals, from CS0 to CS3, are included in the local bus. Of these, only CS0 is
enabled during power-on reset. The chip select signal of the device from which the system
boots should be connected to the local bus through CS0.
Local bus with 8 bits data bus, as well as the control signals, are routed to COM-E connectors.
Local bus signals are disabled by default, and can be enabled through the buffers using the 8th
bit of S1.

4.17 RTC and Watchdog Timer
The RTC and Watchdog Timer (WDT) are integrated in the module through the IC U12, which
is accessed first by the I2C bus, address 0xD0. This device also provides a reset output signal for
the COMX-P4080, as well as a 32 KHz clock output for the RTC. Battery backup for the RTC is
supplied by the VCC_BAT pin on the COM-E connectors.
The WDT is fed by the GPIO 18 of the COMX-P4080.
4.18 Thermal Sensor
The COMX-P4080 module supports both remote and local thermal sensors. The remote
thermal sensor is available when there is a thermal diode provided in the COMX-P4080 and is
accessed by the first I2C bus with the address 0x98.
70
COMX-P4080 COM Express Module Installation and Use (6806800L20C)
The thermal sensor supplies two alarm signals for the system, defined as "ALERT" and "THRM".
When the detected temperature exceeds low temperature limit, an external diode fault will
cause the "ALERT" output to assert "low". This "ALERT" output is connected to the IRQ7 of the
COMX-P4080.
When the detected temperature exceeds the preset high temperature limit, the "THRM"
output will assert "low". The "THRM" signal can be connected to the power enable signal of the
core and platform power sources, and can be used to power down the COMX-P4080. This can
be done by installing the resistor R178, which is not installed by default.
4.19 Debugger
The COMX-P4080 supports the JTAG debugger, which is provided by default.
Debugger selection details can be seen the following figure.
