SBC1491ET from Micro/sys is a full-featured PC/104 (3.55" x 3.775") computer with a sub-5 second boot-up time using an industrial BIOS or DOS operating system.

Based on a high-performance 486/586 core, the SBC1491ET from Micro/sys is a full-featured PC/104 (3.55" x 3.775") computer that has a sub-5 second boot-up time using an industrial BIOS or DOS operating system. The board can operate in a –40°C to +85°C environment and includes standard PC features such as SVGA, dual serial ports, and 10BASE-T Ethernet support.

With 64MB of RAM, up to 576MB solid state flash, and full AT-compatibility, the SBC1491ET is a cost effective mid-range controller. For applications not requiring Pentium speed, the SBC1491ET offers PC-compatibility operating up to 133MHz, yet generates less heat, requires less power and costs less. In its stackthrough version, the SBC1491ET is ideal for plugging onto a custom OEM I/O card or other PC/104 expansion cards. In addition to DOS, software development packages for the SBC1491ET include Linux, Windows CE, and VxWorks.

The SBC1491ET uses an STPC Atlas processor, with operating speeds from 120MHz to 133MHz, on-chip cache, 64-bit DRAM access, hardware floating point support, and AT-compatible interrupt, timer, and DMA controllers. The SBC1491ET has two serial ports, COM1, COM2, SuperVGA, keyboard, and mouse. The SuperVGA includes hardware acceleration, and drives CRT monitors with resolutions up to 1280 x 1024. The 10 MHz Ethernet provides fast, reliable communications. I/O expansion is available by using the popular on-board PC/104 connector.

The large 576MB solid state flash space available on the SBC1491ET can be used as solid-state storage for operating systems other than DOS and large applications. Micro/sys installs a ready-to-run firmware system on the SBC1491ET at no cost. This firmware includes a complete industrial BIOS, board setup screens, and application download utilities, and can create a DOS-like execution environment immediately upon powerup. Borland or Microsoft C/C++ 16-bit .EXE files can be downloaded to the board upon receipt. Alternatively, the computer may be configured to boot 32-bit operating systems upon powerup. A free development kit is provided that includes download cables, sample software, and full documentation. A full cable set can be purchased to support all onboard I/O.

The basic SBC1491ET starts at $512 in single quantity. A commercial temperature version that operates from 0°C to +70°C is also available starting at $455. Optional features are quite cost effective, as they do not require additional boards. Significant OEM discounts are available.
