CMX58886CX cpuModules

RTD's CMX58886CX cpuModule represents the latest in high-performance embedded computing solutions. It includes 400 MHz source-synchronous Front Side Bus (FSB), on-die 512kB L2 cache, and data pre-fetch logic. It uses a 333MHz DDR-SDRAM controller that can support up to 2.7 G-Bytes per second of memory bandwidth. All memory chips are soldered directly onto the board.

The video interface is provided by an Analog SVGA output and an LVDS flat panel output. The two outputs are independent, and can display separate images and display timings. Maximum resolution is 2048 x 1536.

High-speed peripheral connections include USB 2.0, with up to 480 Mb/sec data throughput. An ATA-100/66/33 IDE controller provides a fast connection to the hard drive. Network connectivity is provided by an integrated 10/100 Mbps Ethernet controller. Other features include two RS-232/422/485 COM ports, Parallel Port, and AC97 audio.

RTD has gone the extra mile to include additional advanced features for maximum flexibility. These include an ATA/IDE Disk Chip socket that allows a true IDE drive to be attached to the board, either socketed or soldered. A MultiPort can be configured as a standard EPP/ECP parallel port, a floppy drive port, or an Advanced Digital I/O (aDIO) port. An Advanced Watchdog Timer is provided that can generate and interrupt or reset when the timer expires. The DDR-SDRAM controller uses Error-Correcting-Codes (ECC) to correct single bit memory errors, and detect two-bit memory errors, providing for a more robust memory system. SDRAM is soldered directly to the board for high vibration resistance. The CMX58886CX is also available in a rugged, fanless IDAN enclosure.

Thermal Monitor and Thermal Throttling

The Intel ® Thermal Monitor is a feature on the CMX58886CX that automatically throttles the CPU when the CPU exceeds its thermal limit. The maximum temperature of the processor is defined as the temperature that the Thermal Monitor is activated. The thermal limit and duty cycle of the Thermal Monitor cannot be modified. The Thermal Monitor can be disabled by the BIOS for applications where deteministic speed is more important than device failure due to thermal runaway. In addition to the Thermal Monitor, conventional Thermal Throttling is also provided. This forces the CPU to skip clock cycles when it exceeds a thermal limit. The thermal limit and duty cycle of thermal throttling can be modified in the BIOS.

Error-Correction Codes

The Graphics and Memory Controller Hub (GMCH) may be configured in the BIOS setup to operate in an Error-Correction-Code (ECC) data integrity mode. ECC mode allows multiple bit error detection and single bit error correction. The GMCH generate an 8-bit code word for each 64-bit Qword of memory, and performs a full Qword write at a time so that an 8-bit code is sent with each write. Since the code word covers a full Qword, writes of less than a Qword require a read-merge-write operation. Consider a Dword write to memory. In this case, when in ECC mode, GMCH will read the Qword where the addressed Dword will be written, merge in the new Dword, generate a code covering the new Qword and finally write the entire Qword and code back to memory. Any correctable (single-bit) errors detected during the initial Qword read are corrected before merging the new Dword.

Memory with ECC enabled requires additional system memory resources. This will cause the integrated graphics engine to have less memory bandwidth for access to the graphics frame buffer. Because of this, the display may flicker at high resolutions when the graphics processor is fully utilized and ECC is enabled. ECC memory is supported with internal graphics only.

aDIO with Wake-on-aDIO

RTD’s exclusive multiPort™ allows the parallel port to be configured as an Advanced Digital I/O (aDIO™), ECP/ EPP parallel port, or a floppy drive. aDIO™ is 16 digital bits configured as 8 bit-direction programmable and 8-bit port-direction programmable I/O giving you any combination of inputs and outputs. Match, event, and strobe interrupt modes mean no more wasting valuable processor time polling digital inputs. Interrupts are generated when the 8 bit-direction programmable digital inputs match a pattern or on any value change event. Bit masking allows selecting any subgroup of eight bits. The strobe input latches data into the bit-programmable port and generates an interrupt. Any of the interrupt modes can be used to generate a wake event from any standby/powerdown mode.

You can easily customize the cpuModule by stacking PCI-104 modules such as video controllers, modems, LAN controllers, or analog and digital data acquisition modules. Stacking PCI-104 modules onto the cpuModule avoids expensive installations of backplanes and card cages, and preserves the module's compactness.

The cpuModule uses the RTD Enhanced AMI BIOS. Drivers in the BIOS allow booting from floppy disk, hard disk, ATA/IDE Disk Chip, or boot block flash, thus enabling the system to be used with traditional disk drives or nonmechanical drives. Boot from USB devices and network are also supported.

The cpuModule and BIOS are also compatible with most real-time operating systems for PC compatible computers, although these may require creation of custom drivers to use the aDIO and watchdog timer.

Failure

1. Because the cpuModule has an onboard +3.3V supply, an external +3.3V supply is not required. However, if a +3.3 V supply is installed in the system to power PC/104-Plus or PCI-104 expansion boards, it will be monitored by the CPU at power up.

2. The 12V and -12V rails are not used by the cpuModule. They are only connected between the bus connector and the power connector. Any requirements on these signals are driven by other components in the system.

3. 5V Standby is used to power the board when the main supply is turned off (power down modes S3-S5). It is not required for board operation.

WARNING If you connect power incorrectly, the module will almost certainly be damaged or destroyed. Such damage is not covered by the RTD warranty! Please verify connections to the module before applying power.

Power is normally supplied to the cpuModule through the PCI bus connectors (CN16). If you are placing the cpuModule onto a PC/104-Plus or PCI-104 stack that has a power supply, you do not need to make additional connections to supply power.

If you are using the cpuModule without a PCI-104 or PC/104-Plus stack or with a stack that does not include a power supply, refer to Auxiliary Power (CN3) on page 24 for more details.

Some PCI-104 and PC/104-Plus expansion cards may require +3.3V supplied on the PC/104-Plus (PCI) connector (CN16). To learn how to supply this voltage, refer to Auxiliary Power (CN3) on page 24 and Jumper Settings and Locations on page 80.

BDM-610000050 Rev A Chapter 2: Getting Started 17

Connecting the Utility Cable

The multi-function connector (CN5) implements the following interfaces:

• PC/AT compatible keyboard

• PS/2 mouse port

• Speaker port (0.1W output)

• Hardware Reset input

• Battery input for Real Time Clock

• Soft Power Button input

To use these interfaces, you must connect to the utility port connector (CN5). The utility harness from the RTD cable kit provides a small speaker, two connectors for the keyboard and mouse, a push-button for resetting the PC/104-Plus or PCI-104 system, and a lithium battery to provide backup power for the real time clock.

Refer to Utility Port Connector (CN5) on page 26 to connect devices to the utility port connector .

Connecting a Keyboard

You may plug a PC/AT compatible keyboard directly into the circular DIN connector of the utility harness in the cable kit.

Note Many keyboards are switchable between PC/XT and AT operating modes, with the mode usually selected by a switch on the back or bottom of the keyboard. For correct operation with this cpuModule, you must select AT mode.

Connecting to the PC/104-Plus (PCI) Bus

Other PC/104-Plus or PCI-104 expansion boards may be connected to the cpuModule’s PC/104-Plus (PCI) bus connector. To connect expansion modules to the PC/104-Plus bus, follow the procedure below to ensure that stacking of the modules does not damage connectors or electronics.

WARNING Do not force the module onto the stack! Wiggling the module or applying too much pressure may damage it. If the module does not readily press into place, remove it, check for bent pins or out-of-place keying pins, and try again.

1. Turn off power to the PC/104-Plus or PCI-104 system or stack.

2. Select and install stand-offs to properly position the cpuModule on the stack.

3. Touch a grounded metal part of the rack to discharge any buildup of static electricity.

4. Remove the cpuModule from its anti-static bag.

5. Check that keying pins in the bus connector are properly positioned.

6. Check the stacking order; if a PCI to ISA bridge card is used to connect any PC/104 modules, make sure an XT bus card will not be placed between two AT bus cards or it will interrupt the AT bus signals.

7. Hold the cpuModule by its edges and orient it so the bus connector pins line up with the matching connector on the stack.

8. Gently and evenly press the cpuModule onto the PC/104-Plus or PCI-104 stack.

There are three additional considerations to make when using the PCI bus:

• Slot selection switches on add-in boards

18 CMX58886CX cpuModule BDM-610000050 Rev A

• PCI bus expansion card power

• PCI bus signaling levels

Slot Selection Switches

Unlike PC/104 cards, PC/104-Plus and PCI-104 expansion cards have a "slot" selection switch or jumpers. In total, there are 4 PCI cards that can be stacked onto the cpuModule with switch positions 0 through 3. The distance from the CPU determines these switch settings. The card closest to the CPU is said to be in slot 0, the next closest slot 1 and so on to the final card as slot 3.

Note This requirement means that all PC/104-Plus and PCI-104 cards must be stacked either on the top or the bottom of the CPU, not on both sides.

The "slot" setting method may vary from manufacturer to manufacturer, but the concept is the same. The CPU is designed to provide the correct delay to the clock signals to compensate for the bus length. The correct switch setting ensures the proper clock delay setting, interrupt assignment, and bus grant/request channel assignment. Refer to the expansion board’s manual for the proper settings. Each expansion card must be in a different slot.

PCI Bus Expansion Card Power

+5 Volt DC

The +5 V power pins on the PC/104-Plus (PCI) bus are connected directly to the +5 V pins on the auxiliary power connector, CN3 (pins 2 and 8).

+3.3 Volt DC

The factory default configuration is to connect the +3.3 V pins on the PCI bus to the auxiliary power connector (CN3) by soldering pins 1–2 on solder blob, B3 (see Table 58 on page 82 for solder blob settings). This is to ensure that the cpuModule’s onboard +3.3V supply will not supply power to the PC/104-Plus connector while a PC/104-Plus or PCI-104 power supply is already powering the +3.3V pins.

To supply +3.3V to PC/104-Plus or PCI-104 expansion boards with the onboard +3.3 V power supply, change B3 from pins 1–2 to pins 2–3. In this configuration, the current limit of the +3.3V connection to the PCI +3.3V via

B3 should not be exceeded (see Table 58 on page 82 for current limitation).

PCI Bus Signaling Levels

The PCI bus can operate at +3.3 V or +5 V signaling levels. The signaling levels for the I/O pins on a PCI bus card are determined by solder blob B1. The default is +3.3 V. Refer to Table 58 on page 82 for solder blob settings.

WARNING You will have to ensure that all your expansion cards can operate together at a single signaling level.

BDM-610000050 Rev A Chapter 2: Getting Started 19

Booting the CMX58886CX cpuModule for the First Time

You can now apply power to the cpuModule. You will see:

• A greeting message from the VGA BIOS (if the VGA BIOS has a sign-on message)

• The cpuModule BIOS version information

• A message requesting you press Delete to enter the Setup program

If you don’t press Delete, the cpuModule will try to boot from the current settings. If you press Delete, the cpuModule will enter Setup. Once you have configured the cpuModule using Setup, save your changes and reboot.

Note You may miss the initial sign-on messages if your monitor takes a while to power on.

Note By default, cpuModules are shipped with Fail Safe Boot ROM enabled. When Fail Safe Boot ROM

is enabled, the system will boot to it exclusively.
