2.1 Introduction

CCOMe-C30 is a carrier board, designed in 3.5” form factor, intended for the use with COM-Express Type 6 CPU modules. COM-Express is an open industry standard defined specifically for COMs (computer on modules). Its definition provides the ability to make a smooth transition from

legacy parallel interfaces to the newest technologies based on serial buses available today. COM Express CPU modules integrate all the core components of a typical PC-like architecture, and make all interface available through two standardized

connectors, so that COM Express modules become scalable. This means that once an application has been created, there is the ability to diversify the product range through the use of different performance class or form factor size modules.

Baseboard designers can use just the I/O interfaces that really need, providing, on the carrier board, the routing to the adequate interface connectors. This versatility allows the designer to create a dense and optimised package, which results in a more reliable product while simplifying system integration. CCOMe-C30 board can be used both as an evaluation module, to test the functionality of your COM-Express module and design an application specific carrier

board for it, or as a complete carrier board, already suited for standard purposes, with a small space consumption. In any case, the solutions so realised is fully scalable, and allows to the user to keep his own-designed system continuously up-to-date, since the system can be

updated simply replacing the COM-Express module with a newer one, just unplugging the module and replacing it, without the need of redesigning it. The robust thermal and mechanical concept, combined with extended power-management capabilities, is perfectly suited for all applications.

3.3.2 SATA connectors

For the connection of external Mass Storage Devices, there is a standard male SATA connectors, CN6. These connectors carry out directly SATA port #1 signals coming from COM Express module’s

connector. Please notice that each SATA connector will work only in case the COM Express module carries out

SATA Channel #1 on COM Express connector (pins B16, B17, B19 and B20). In case the COM Express module used doesn’t have these signals connected, then one or both of these connectors will not be usable.

A dedicated power connector, CN 8, can be used to give supply to external Hard Disks (or Solid State Disks) connected to the SATA male connector.

The dedicated power connector is a 4-pin male connector, type HR p/n A2001WV-S-04 or equivalent, with pinout shown in the table on the left.

Mating connector: HR A2001H-04P housing with HR A2001 series crimp terminals.

Here following the signals related to SATA interface: SATA1_TX+/SATA1_TX-: Serial ATA Channel #1 Transmit differential pair. SATA1_RX+/SATA1_RX-: Serial ATA Channel #1 Receive differential pair.

3.3.21 Switch / LED header interface

To allow the integration of a CCOMe-C30 based system inside a box PC-like, there is a connector on the carrier board that allows to remote signals for the Power Button (to be used to put the system in a Soft Off State, or awake from it), for the Reset Button, and the signal for optional LED signalling activity on SATA Channel and Power On states.

The pinout of this connector complies with Intel® Front Panel I/O connectivity Design Guide, Switch/LED Front Panel section, chapter 2.2. It is shown in the table on the left.

Connector CN19 is an internal 9-pin standard male pin header, p 2.54 mm, 5+4 pin, h= 6mm, type NELTRON p/n 2213S-10G-E10 or equivalent.

Signals Description: HD_LED_P: Hard Disk Activity LED signal’s pull-up to +5V_S voltage (510Ω pull-up). HD_LED_N: Hard Disk Activity LED output signal. RST_SW_N: Reset Switch GND. RST_SW_P: Reset switch input signal. This signal has to be connected to an external momentary pushbutton (contacts normally open). When the pushbutton is

pressed, the pulse of Reset signal will cause the reset of the board. PWR_SW_P: Power switch input signal, open drain. This signal has to be connected to an external momentary pushbutton (contacts normally open). Upon the

pressure of this pushbutton, the pulse of this signal will let the switched voltage rails turn on or off. PWR_SW_N: Power Switch GND. FP PWR_P/SLP_N: Power/Sleep messaging LED terminal 1 with 510Ω pull-up resistor to +5V_A voltage. Connect it to an extremity of a dual-colour power LED for

power ON/OF, sleep and message waiting signalling. Please refer to Intel® Front Panel I/O connectivity Design Guide, chapter 2.2.4, for LED functionalities and signal meaning.

FP PWR_N/SLP_P: Power/Sleep messaging LED terminal 2 with 510Ω pull-up resistor to +5V_A voltage. Connect it to the other extremity of the dual-colour power LED

above mentioned.

Please be aware that the power switch input signal and the reset switch input signal are also managed directly on the carrier board by the two pushbuttons SW1 and SW2 (respectively), so it is not mandatory to connect them externally using CN19.

As already written in the previous paragraph dedicated to Audio interface, it is also possible to buy SECO’s dedicated front panel module, which offers two standard audio jacks, two pushbuttons (for reset and power on) and two LEDs, for SATA activity and Power status signalling.

• Thermal Design

CCOMe-C30

54

4.1 Thermal Design

A parameter that has to be kept in very high consideration is the thermal design of the system. Highly integrated modules, like COM Express modules, offer to the user very good performances in minimal spaces, therefore allowing the systems’ minimisation.

On the counterpart, the miniaturising of IC’s and the rise of operative frequencies of processors lead to the generation of a big amount of heat, that must be dissipated to prevent system hang-off or faults.

COM Express specifications take into account the use of a heatspreader, which will act only as thermal coupling device between the COM Express module and an external dissipating surface/cooler. The heatspreader also needs to be thermally coupled to all the heat generating surfaces using a thermal gap pad, which will optimise the heat exchange between the module and the heatspreader.

The heatspreader is not intended to be a cooling system by itself, but only as means for transferring heat to another surface/cooler, like heatsinks, fans, heat pipes and so on.

Conversely, heatsinks in some situation can represent a cooling solution. Until the modules are used on a development Carrier board, on free air, just for software development and system tuning, then a finned heatsink with fan could be sufficient for modules’ cooling. Anyhow, please remember that all depends also on the workload of the processor. Heavy computational tasks will generate much heat.

Indeed, when using CCOMe-C30 carrier board with any COM Express module, it is necessary to consider carefully the global heat generated by the system, and the scenario of utilisation.

Therefore, it is always necessary that the customer study and develop accurately the cooling solution for his system, by evaluating processor’s workload, utilisation scenarios, the enclosures of the system, the air flow and so on. This is particularly needed for industrial grade modules.

SECO can provide COM Express modules’ specific heatspreaders and heatsinks (active and passive), but please remember that their use must be evaluated accurately inside the final system (electronics + mechanics), and that they should be used only as a part of a more comprehensive ad-hoc cooling solutions, which also keeps the surface temperature of all carrier board’s components in the temperature range specified for the specific carrier board configuration (industrial or commercial grade).

CCOMe-C30

4.2 Accessories

SECO can offer the following accessories in completion of CCOMe-C30 functionalities

4.2.1 Front Panel I/O board

As described in paragraphs 3.3.17 and 3.3.21, SECO can provide a specific module, the

Front Panel I/O board

V995, which allows to remote on a panel of an optional enclosure two Audio jacks (Headphone and Mic in), Reset Button, Power button and two LED (for SATA activity and Power Status of the board itself).

For fixing of the front panel I/O board to the external enclosure’s panel, the module is equipped with two brackets and screws for the fixing of the brackets to the module.

Please be aware that this module is useful only for remoting the buttons and the audio jacks, but it is not needed for working of CCOMe-C30 board. Indeed, Power and Reset button functionalities are ensured also by the two pushbuttons SW1 and SW2 embedded on the carrier itself. Only the Audio functionalities are not directly

exploitable on the carrier board.

Depending on the type of serial port needed, different module configurations are available; moreover, the output of the module can be available on standard DB-9 male connector or on RJ-45 sockets.

Using these modules, it will be possible to have additional serial ports, other than those available on connector CN27.

All modules type mounts an FTDI FT232R USB-to-Serial UART interface IC; RS-232 converter module then mounts a Serial Port RS-232 Transceiver with 15kV ESD protection. Instead, the other converters mount an RS-485/RS422 transceiver.

In the table on the left are shown the pinout of DB-9 connector and of RJ-45 socket for all kind of modules.

120Ω termination resistors on differential pairs are available both on RS-422 and on RS-485 modules.

4.2.3 eDP-to-LVDS converter

This optional module has been designed to convert the eDP interface available on connector CN33 into a Single or Dual Channel 18- / 24-bit LVDS interface by using an NXP PTN3460I eDP to LVDS bridge.

The eDP interface of the module is carried to another VESA® certified connectors for embedded Display Port interface, type STARCONN p/n 300E40-0110RA-G3 or equivalent (microcoaxial cable connector, 0.5mm pitch, 40 positions). It is the same identical connector to CCOMe-C30 board’s connector CN33. The pinout is shown in the table on the left.

Only 2-lane eDP interface is required for this module. For signals’ description please refer to paragraph 3.3.14 SW_VDD and SW_BACK voltages are used only to drive the display, they are not used for

module’s working (see further on).

All the signals necessary for working of the eDP to LVDS converter module can be found on connector CN2, which can be paired to CCOMe-C30 board using a 1:1 direct cable connection.

For the occurrences when the module is paired to different boards, or when the SM_Bus is not working / connectable on connector CN2, then the module offers also the possibility of connecting to another board’s I2C interface using a dedicated 16-pin connector. Such a connector is available in two factory option, as a male 2x8 pin header p 2.54mm h= 6mm (CN5), or as a female 2x8 pin connector, p2.54mm, h=11.04mm type NELTRON p/n 2214123-16G10-1B-32 (CN4) for piggyback connection

GP_I2C_CLK: General Purpose I2C Clock line GP_I2C_DAT: General Purpose I2C Data line LVDS_RST#: General purpose Input signal. Can be used for LVDS

section’s reset. 3.3V input signal with 100kΩ pull-up resistor, active low.

The I2C bus available on connectors CN4/CN5 can be used in alternative to SM Bus interface available on connector CN2 to manage the eDP to LVDS bridge. It is necessary to configure properly the module in order to use the General Purpose I2C bus (CN4/CN5) or SM Bus (CN2). The selection must be made using

module’s dip switch SW1

Setting of these signals can be made according to the table on the left.

When MC30’s jumper JP13 is placed, it is suggested to set both SW1 switches in position ON. The COM express module plugged on MC30 Carrier, however, must be able to support the eDP to LVDS bridge through its SM Bus interface
