CME136686LX cpuModules RTD's CME136686LX cpuModule represents the latest in reliable low-power performance embedded computing solutions. It includes a 500 or 333MHz AMD Geode LX processor with 128kB L1 cache (64kB instruction and 64kB data) and 128kB L2 cache. It uses a 333MHz DDR-SDRAM controller that can support up to 2.7 G-Bytes per second of memory bandwidth. 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 1920 x 1440. 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 two Intel 82551QM Ethernet controllers. Other features include two RS-232/422/485 COM ports (four ports if in dual-port mode). 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 an interrupt or reset when the timer expires. SDRAM is soldered directly to the board for high vibration resistance. The CME136686LX is also available in a rugged, fanless IDAN enclosure. You can easily customize the cpuModule by stacking PC/104 modules such as video controllers, modems, LAN controllers, or analog and digital data acquisition modules. Stacking 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. Booting 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. 10 CME136686LX cpuModule BDM-610000065 Rev C

Match, event, and strobe interrupt modes prevent 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. BDM-610000065 Rev C Chapter 1: Introduction 11
