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.
