The SBC1390 is a powerful controller in a PC/104 footprint that will communicate with other computers in a wireless network. In addition to PC-compatible features—such as four serial ports, three timer/counters, and two cascaded interrupt controllers—the new model can also include an on-board PC card interface that accepts a WiFi (IEEE 802.11b) wireless Ethernet card.

In addition to the wireless network capability, the SBC1390 has other features that make it a full-blown embedded PC. The SBC1390 is implemented with the Intel 386EX processor, which offers speeds of 25 or 33 MHz. With up to 32 MB of SDRAM, a CompactFlash connector, a synchronous serial port, a watchdog timer, and AT-compatibility, high-performance control systems can be developed as single-board solutions. If needed, I/O expansion can be added to the SBC1390 through PC/104 cards. In its stack-through version, the SBC1390 is ideal for plugging into a custom OEM I/O card.

The CompactFlash connector can accept flash memory cards from 16 MB to 1 GB in size. The unit comes installed with a ready-to-run firmware system. This firmware includes a complete industrial BIOS, board setup screens, application download utilities, and a DOS-compatible operating system that boots immediately upon power-up. Alternatively, the board may be configured to boot 32-bit operating systems.

The following are options: a PC card interface, a WiFi PC card, CompactFlash, increased DRAM, and an enhanced accuracy real-time clock. An industrial version with –40° to 85°C operation is also available.

The basic SBC1390, with 16 MB of DRAM and 1 MB of flash memory, costs $315. A free development kit is provided that includes cables, sample software, and full documentation.
