2.5. Differences between Robin V2.0 to Robin V1.0
By Robin V1.0 and V2.0 the PCB version is meant.
2.5.1
DDR2 x8 instead of x16 DDR2
Robin V2.0 utilizes DDR2 RAM devices with a x8 bit bus width in contrast to Robin V1.0, which utilizes
DDR2 RAM devices with x16 bit bus width. This allows Robin V2.0 to provide up to 2GByte of RAM, in
comparison with the maximum 1GByte of RAM available on Robin V1.0.
2.5.2
SDIO / GPIO switch
Robin V2.0 provides either a GPIO or SDIO interface on the COM Express connector. The same
GPIO signals available on the FFC connector of Robin V1.0 are also available on Robin V2.0.
2.5.3
PCB thickness
The Robin V2.0 PCB has a nominal thickness of 2mm compared to 1.6mm for Robin V1.0.
This may have an impact for customers who have implemented a mechanical design that is affected
by PCB thickness. To ensure compatibility between Robin V1.0 and V2.0 in such designs, Toradex will
provide a dedicated Heatspreader for Robin V2.0, which will compensate for the PCB height
difference.
2.5.4
FFC shifted
The FFC connector has been shifted closer to the PCB edge with respect to the front edge of the
connector. Its position with respect to the adjacent PCB edge has not changed.
2.5.5
Thermal sensor
The thermal sensor has been moved away from the key heat sources (the Atom processor and
US15W system control hub) to provide a more accurate measurement of the module temperature. The
Atom processor temperature is still measured internally to the core.

4.2. Serial ATA
The Serial ATA (SATA) interface is provided through the JMH330 IDE to SATA Bridge from JMicron.
No additional driver is required for the SATA interface.
4.3. USB Interface
The US15W (System Controller Hub on the Robin module) features Enhanced Host Controller
Interface (EHCI) with 8 USB ports. All 8 ports support USB high speed (480Mbit/s). However, it should
be noted that only 6 of these ports support low speed (1.5Mbit/s) and full speed (12Mbit/s).
7 USB ports are available through the COM Express™ connector. Port 5 of the US15W is used for
communication with the Robin Embedded Controller and is therefore not available on the module
connector..

4.4. Ethernet Controller
The Robin Z5xx module features an onboard RTL8111C/D gigabit Ethernet controller from Realtek
which supports a 10/100/1000 Base-T interface. This controller is directly connected to the PCI
Express interface of the US15W. The device auto-negotiates the use of the different speeds and
includes features such as crossover detection with auto-correction, polarity correction and cross-talk
cancellation.
For high volumes, the Robin module can be assembled with the RTL8102E Ethernet controller instead
of the RTL8111C/D. This offers a suitable solution for very price sensitive, high volume projects
requiring only a 10/100 Base-T fast Ethernet controller (please contact Toradex for further
information).
4.5. PCI Express
The US15W chipset features two x1 PCI Express lanes. PCIe lane 0 of the US15W is directly
available at the COM Express™ connector. PCIe lane 1is connected directly to the Ethernet controller
and is not available for general use.
4.6. ExpressCard
The Robin Z5xx module supports the two additional signals required for the ExpressCard interface
(card detect and card reset). The ExpressCard interface makes use of both a USB port and a single
PCI Express lane (although an attached ExpressCard device may only make use of one of these
interfaces).
4.7. SDIO, SD Card and MMC
The Intel® US15W features 3 SDIO buses. Each SDIO bus can be used for SD cards,
MultiMediaCards (MMC), as an SDIO interface or CE-ATA interface. The SD card and the SDIO
interface can run in either 1 bit or 4 bit mode, whereas MMC supports an additional 8 bit transfer
mode. Only SDIO slot 2 of the US15W is 8 bit capable; the other two are only 4bit capable.
SDIO slot 1 is available on the Robin module as MicroSD card holder. Slot 0 is on the COM Express™
connector (see chapter 3.3.1) and slot 2 is available on the 30 pin FFC connector. This connector also
provides 3.3V power supply for SD or MMC cards. Please note that as the maximum power rating of

Page | 20
Robin Z5xx Datasheet
the 3.3V supply on this connector is limited, an additional power supply may be required if the
connected SDIO device has a power requirement which exceeds this rating.
4.8. VGA
The Robin module features a Chrontel SDVO to VGA and TV out converter CH7022. Please refer to
the datasheet for more information.
For application specific/custom carrier board designs, remember to include the 150R load resistors
required at each of the VGA color outputs.
For high volumes, it is an assembly option not to fit the CH7022. The SDVO signals would then be
routed to the COM Express connector. Please contact Toradex for further information regarding
assembly options.
4.9. TV out
The Robin module features a Chrontel SDVO to VGA and TV out converter CH7022. Please refer to
the datasheet for more information.
For application specific/custom carrier board designs, remember to include the 150R load resistors
required at each of the TV outputs.
For high volumes, it is an assembly option not to fit the CH7022. The SDVO signals would then be
routed to the COM Express connector. Please contact Toradex for further information regarding
assembly options.

5. Power Supply
5.1. Power States
State
Common Names
Behavior
G3
Mechanical Off
All power supplies except the RTC battery are removed. The power consumption of the
system is almost zero; only the RTC circuit consumes a small amount of power
S5
Soft Off
Only the embedded controller on the module is powered. The embedded controller waits for
the power button to be pushed before starting the system. The power consumption in this
state is very low.
S4
Suspend to Disk
Hibernation
The contents of RAM are written to a non-volatile storage medium (e.g. hard disc). This allows
recovery of the system to the state prior to entering suspend or hibernate. From the hardware
perspective, this state is equal to S5. The system is off except for the embedded controller
being powered. The embedded controller waits for the power button to be pushed before
starting the system. The power consumption in this state is very low. The Robin hardware
does not distinguish between S4 and S5.
S3
Suspend to RAM
Stand by, Sleep
The RAM subsystem is powered for a fast recovery of the system. Power supplies that are not
required are switched off. Wake on LAN is supported in this state (hence the network
subsystem is powered). The Robin module requires the main power supply to generate the
standby power supply.
S0
On
The system is working. All power supplies are switched on. The power consumption depends
on the CPU and peripheral load.
The COM Express Connector features three signals for signaling the different power states to the
carrier board. As the Robin module hardware does not distinguish between power states S4 and S5,
SUS_S4# and SUS_S5# are essentially the same signal.

Robin Z5xx Datasheet
5.2. Power Supply
The Robin modules are designed to run from a single power supply with a wide nominal input voltage
range of +5V to +12V. Two power supplies are optional: a +5V standby power supply and a +3V
battery power supply (used to power the real-time clock on the module).
If the standby power supply is not provided by the carrier board, the Robin module will generate the
required standby power from the main power supply using a linear voltage regulator. Hence, the Robin
module supports both the S4 and S5 power states even if the standby power supply is absent, as long
as the main power supply is present.
The RTC power supply is powered in parallel by both the standby power supply and the 3V battery
power supply. This ensures that the real-time clock is running as long as either one of these power
supplies is present. Important: a diode must be placed between RTC Battery and the RTC Voltage pin
of the module connector.
5.2.1
AC Power Adaptor
Depending upon the specific hardware configuration, it is likely that the power supply to the carrier
board will be forwarded directly to the Robin module (this is true for Lily V1.0, V1.1, V2.0, V2.1 and
Daisy V1.0, V1.1). If an AC power adaptor is being used, please ensure that its output voltage is never
beyond the limits of the module and carrier board. Simple AC power adaptors may have significantly
higher output voltages than their nominal voltage in no-load operation; usage of such power adaptors
can damage both the Robin Z5xx module and carrier board.

If the carrier board features a 5V standby power supply, the main power rail can be switched off in
power states S5 and S4. The SUS_S5# or SUS_S4# signal can be used for switching the main power
supply. If the carrier board features an ATX Power supply, the SUS_S5# signal is used to drive the
PS_ON pin of the ATX power supply through a level shifter. The Power good signal from the ATX
power supply can be used directly without level shifter as the PWR_OK signal for the Robin module.
With this power control method, the carrier board must manage the following power sequence:
1. Robin module de-asserts the SUS_S5# and SUS_S4# signal.
2. The carrier board must switch on the main power supply and the necessary power supplies for
the peripherals on the carrier board.
3. If all required power supplies on the carrier board are stable, the carrier board shall indicate
this to the Robin module through the PWR_OK signal. This must be done within 15 seconds
of the SUS_S5# signal being de-asserted. Otherwise the Robin module shall enter the power
state S5 (power fail). The Robin module can be configured to retry the power up sequence
after 1 minute (see section 6.5.1).
4. The Robin module ramps up all the necessary power supplies to enter power state S3 and deasserts the SUS_S3# signal.
5. The Robin module continues its power up process by ramping up the remaining on-board
power supplies, releasing the reset signal and booting.

It is also possible to use the signal SUS_S3# for controlling the main power supply, which is the
mechanism employed by some commercially available COM Express carrier boards. To support this
power control method, the Robin module requires a change to a setting in the embedded controller
which enables S3 Signaling Mode. When operating in S3 Signaling Mode, the module de-asserts both
SUS_S3# and SUS_S5# simultaneously. Section 6.5.2 describes this in more detail. S3 Signaling
Mode can be configured using the Toradex Z5xx Tweaker tool.
For new designs, Toradex does not recommend using this power control method and hence hardware
configuration, as it is not possible for the carrier board to differentiate between power states S5 and
S3.
With this power control method, the carrier board must manage the following power sequence:
1. The Robin module de-asserts signals SUS_S5#, SUS_S4#and, if S3 Signaling Mode is
enabled, SUS_S3#.
2. The carrier board must switch on the main power supply and the necessary power supplies for
any carrier board peripherals.
3. If all required power supplies on the carrier board are stable, the carrier board must assert the
PWR_OK signal within 10 seconds of the de-assertion of signal SUS_S5#. In the event that
this fails to happen, the Robin module will de-assert signal SUS_S3# if it has not already done
so in step 1 (this allows the Robin module to successfully power on in order to enable S3
Signaling Mode). If a further 5 seconds elapses without the PWR_OK signal asserted, the
Robin module returns to power state S5 (power fail). The embedded controller can be
configured to retry the power up sequence after 1 minute (see section 6.5.1).
4. The module ramps up all the necessary power supplies to enter power state S3.
5. The Robin module continues its power up process by ramping up the remaining on-board
power supplies, releasing the reset signal and booting.
Note that it is very important to enable S3 Signaling Mode when using this power control method,
otherwise the shut-down and suspend power modes will not function correctly, and an additional 10
seconds will be added to the power on time.

If the VCC_5V_SBY is not provided by the COM Express carrier board, the Robin module will
automatically generate its own standby power supply from the main power supply. It is therefore still
possible to make use of the power states S4 and S5 if the main power supply is available. In this
configuration, the standby power supply is generated using a linear voltage regulator, and so the
Robin module power consumption whilst in power state S3, S4 or S5 is slightly higher than when the
standby power supply is provided by the carrier board (power consumption measurements are
published in section 9.1).
By default, the embedded controller is programmed to start the system as soon as the main power
supply is available if the standby power supply from the carrier board is not available. The Robin
module can, however, be configured to stay in the power state S5 even after the main power supply is
made available. Section 6.5.1 describes the configuration of this behavior.

In the minimum power configuration, the carrier board only provides the main power supply to the
Robin module. As long as the main power supply is available, the real time clock will run. This
configuration may be suitable for battery powered systems with a non-removable main battery, or for
systems without the requirement for a real time clock.

6. Robin Embedded Controller
The embedded controller on the Robin computer module is a PSoC CY8C24794 from Cypress. The
PSoC is a powerful 8 bit microcontroller with USB interface and analog user blocks. The key
responsibilities of the embedded controller are to provide the power management, watchdog
functionality, user GPIO system and I2C interface.
The firmware used in the Robin Embedded Controller is compatible with the Toradex Oak Sensor
family. For core functionality, the same software libraries can be used. The embedded controller
appears in the operating system as standard USB Human Interface Device (HID). Therefore, for all
major operating systems, no additional drivers are necessary. The communication protocol
implemented in the embedded controller makes use of three different report modes. The INTERRUPT
OUT report mode is used to control the GPIO ports of the embedded controller and to service the
watchdog in real time with a maximum latency of 1ms. The INTERRUPT IN report mode allows the
embedded controller to transmit real time data relating to GPIO status and I2C bus data back to the
main processor. The FEATURE report mode is independent from the interrupt scheduled report
modes and is used as bidirectional non-real time communication channel for configuring power
management, watchdog and GPIO settings.
6.1. INTERRUPT OUT Report Contents (Real time data)

Frame Number
The frame number is a millisecond counter that counts up to 2048 before rolling over. The USB host
controller polls the embedded controller requesting an interrupt in report every millisecond,
incrementing the frame number for each request. The embedded controller copies this frame number
into the interrupt in report to allow the corresponding request to be easily identified. The frame number
can therefore be used for measuring the time between two interrupt in report requests or identify lost
messages.

6.3. FEATURE Report Commands for GPIO
The feature report commands are used for writing and reading embedded controller settings. Settings
can be written into either RAM or flash. The settings stored in RAM are volatile and will be lost when
the main power supply and standby power supply are disconnected. Settings written to flash will be
automatically copied into RAM and will take effect immediately. Please also refer to the “Programming

6.6. Toradex Z5xx Tweaker Tool
The Toradex Z5xx Tweaker Tool is a powerful tool for configuring the settings of the embedded
controller. The program is divided into 4 sections: GPIO, Watchdog, Power Management and
Miscellaneous. The current settings of the embedded controller are read when the tool is invoked.
Changes to setting that are made in the program are written directly to the embedded controller
volatile memory (RAM). Changes can be made persistent using the save-to-flash-button available for
each section.
In addition to the feature report settings described in section 6.3, the Tweaker Tool allows the
embedded controller serial number to be changed. The serial number can be changed according to
user requirements - this serial number is not used by Toradex for module identification or traceability
purposes.

7. Watchdog
The watchdog is implemented in the embedded controller on the Robin module. It is designed to
enable the system to respond to and recover from unexpected events which cause the operating
system or application software to hang up or stop responding. The watchdog can either restart the
system or signal to the carrier board that a watchdog event has occurred. The configuration of the
watchdog is described in section 6.4. The following figure provides a functional description of the
watchdog in the form of a Mealy Finite State Machine (FSM).

Condition
/ Action

Watchdog off: If the system is in the S5, S4 or S3 state, the watchdog is in this state. The
FSM is also in this state if the watchdog is disabled.

Power UP: This state checks for malfunctions in the power up sequence. If the power up to
S0 exceeds 90 seconds, the watchdog initializes a restart of the power up sequence.
Important: this function only monitors the hanging up of the power up sequence. If a power
supply that was ramping up correctly fails later on in the sequence, the watchdog will not
restart the system. If the system needs to restart after such a power failure has occurred, the
boot mode must be set to reboot (see section 6.5.1)

Wait first service: After the correct power up sequence, the watchdog waits in this state for a
period of time equal to the watchdog enable delay (see section 6.4.3). This initial delay allows
extra time for the operating system and the application to start. As soon as the watchdog is
serviced for the first time, the watchdog transitions to the normal running state. If a timeout
occurs before the watchdog is initially serviced, the watchdog transitions to fault state. If the
watchdog transitions from the “Wait first service” state into the “Watchdog fault” state more
than 5 times without being serviced, then it will transition to the “Watchdog temporary off”
state.

Running Normally: The system is in the normal running state. If the watchdog is not serviced
within the strobe interval time, the watchdog transitions into the fault state.

Robin Z5xx Datasheet

Watchdog temporary off: If the watchdog is in this state, then the watchdog was not serviced
for 5 consecutive times prior to the enable delay timeout expiring. This could be due to the
enable delay time being set too short or the system takes a longer time to boot than the time
that has been allowed. This watchdog state allows such configuration issues to be resolved.

Watchdog fault: Depending on the watchdog mode, the system may be reset on the exit
transition from this state. Irrespective of the watchdog mode, the of watchdog mode, the WDT
signal (COM Express Connector Pin B27) will be asserted on entry to this state. This signals
the watchdog event to the carrier board. The WDT signal must be reset using a USB feature
report.

8. Thermal considerations
Thermal management is an important part of a Design with a Robin Z5xx module. Designers must
analyze the application and design an appropriate thermal solution. Toradex provides heatsink or
heatspreader as a possible part for a final design.

8.2. Notes for a custom heatsink or heatspreader

DO NOT use electrically conductive thermal grease, paste or interface material!!!

Using thermal grease is not recommended

The height of the SCH and CPU varies; the thermal solution must be adaptive to the height.
See chapter: 9.3.3 Details with height information

Using a thermal gap pad (=TIM (thermal interface material)) instead of thermal grease is
highly recommended.

Recommended TIM:

o
TIM thickness: 1mm
o
TIM Hardness: <40 (Shore 00)
o
TIM Thermal conductivity: >5 W/(mK)
o
TIM Resistance: >10^13 Ohm
Recommendation for distance from nominal CPU/SCH height to Heatsink: 0.5mm if using
recommended TIM (thermal interface material).
o
Distance from PCB to Heatsink for SCH:
2.4 mm
o
Distance from PCB to Heatsink for CPU:

8.3. Temperature sensor chip
Robin Z5xx uses a temperature sensor chip which continuously measures its own and the CPU
temperature. The temperature sensor chip reads the CPU temperature by means of a diode inside the
CPU.
The two temperatures measured from the sensor chip:

CPU temperature (BIOS: <Current CPU temperature>)

Module temperature (BIOS: <Current System temperature>)
The sensor chip has two output signals:

Warning signal

Critical Temperature signal
8.3.1
Warning signal
For the Warning signal, there is only one temperature limit, which applies for both, the CPU and the
module. It can be seen in the BIOS under <PC Health Status>.
The Warning signal may throttle the CPU by help of the OS and the BIOS.
8.3.2
Critical Temperature signal
For the Critical signal, there is a temperature limit for each, the CPU and the Module temperature.
They can be seen in the BIOS under <PC Health Status>.
