RTD's CMA157886 CPU Module includes 400 MHz source-synchronous Front Side Bus (FSB), on-die 2 MB (PX) or 512 kB (CX) L2 cache, and data pre-fetch logic. It uses a 333 MHz 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 Pentium-M (PX) processor features Enhanced Intel SpeedStep® technology, which enables real-time dynamic switching between multiple voltage and frequency points. This results in optimal performance without compromising low power.
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.
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.
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.
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 CMA157886 is also available in a rugged, fanless
IDAN enclosure.
