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 outp

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

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 progr

Ordering Information The CMX58886CX cpuModule is available with a 1.0 GHz processor and 256 or 512 MB of DDR SDRAM. The cpuModule can also be purchased as part of an Intelligent Data Acquisition Node (IDAN™) building block, which consists of the cpuModule and a milled aluminum IDAN frame. The IDAN building block can be used in just about any combination with other IDAN building blocks to create a simple but rugged PC/104 stack. Refer to Appendix C, IDAN™ Dimensions and Pinout, for more infor
