The PCM-SC520 is a PC/104-compatible SBC based on the low-power, high-integration AMD SC520 CPU. Included on the PCM-SC520 module are four COM ports and a 10/100 Ethernet controller, making it ideal for thin client and other network-enabled applications. It measures 3.6² × 3.8² and will run x86-compatible software for space- and power-limited embedded designs over an extended temperature range of –40° to 85°C.

The PCM-SC520 supports 32-, 64-, 128-, or 256-MB of SDRAM. Either a CompactFlash card or an M-Systems DiskOnChip flash memory device can be installed for solid-state disk storage of up to 1 GB. 

The controller also includes an 82559ER integrated Ethernet controller. It has a 32-bit PCI interface and supports 10- and 100-Mbps data transfers in both Full- and Half-Duplex modes. Four 16C550-compatible UARTs support RS-232 serial data communication up to 115,200 bps. RS-422/485 levels are supported on COM 1 and 2. Other peripheral functions supported include: a floppy disk controller, an IDE hard disk interface, a keyboard controller, an LPT interface, a mouse port, a battery-backed real-time clock, a precision power-fail reset circuit, and a programmable watchdog timer.

The PCM-SC520 requires only 5 V and draws 900 mA (typically) with 128 MB of SDRAM installed.

The PCM-SC520-0 costs $399.
