The PCM-SC520 is a PC/104-compatible single-board computer (SBC) based on the low power, high-integration AMD SC520 CPU. Included on the PCM-SC520 module are four serial COM ports and a 10/100 Ethernet controller making it suitable for thin-client and other network-enabled applications. It measures 3.6 by 3.8 in. and runs x86-compatible software for space- and power-limited embedded designs over an extended temperature range of -40°C to +85°C.
The PCM-SC520 supports 32-, 64-, 128-, or 256-Mbytes of SDRAM. It's field upgradeable because it's mounted in a standard SODIMM socket. However, it can be ordered with up to 32 Mbytes of soldered down SDRAM for high shock and vibration applications. Either a CompactFlash card or an M-Systems DiskOnChip flash memory device can be installed for solid state disk storage of up to 1 Gbyte.
An Intel 82559ER integrated Ethernet controller is included. Four 16C550-compatible UARTs support RS-232 serial data communication up to 115,200 bits/s. RS-422/485 levels are supported on COM 1 and 2. Other peripheral functions include a floppy disk controller, an IDE hard disk interface, a keyboard controller, a battery-backed real-time clock, and a programmable watchdog-timer. The list price for the PCM-SC520-0 is $399. More information is available at www.winsystems.com.
