25 MHz PC-Compatible Fanless Embedded Computer

Lifecycle: Retired | Released: April 1999

The TS-2100 is an Embedded Single Board Computer (SBC) that features an Intel 386EX 25 MHz CPU and a set of I/O interfaces.

  • Easy embedded application development
  • Reliable deployment and ruggedness
  • DOS operating system preloaded
$249 (Qty. 1)
No minimum order quantity on standard products.

The model TS-2100 is a compact, full-featured PC compatible Single Board Computer based on the 386EX processor. If you are coming up from the 8-bit micro controller world, you will find that this product provides much more performance and much quicker development since you can now use standard PC development tools such as Turbo C or Quick Basic. If you have done work in the PC world in the past, you will find you can now build applications for a very small target that does not require a keyboard, video, floppy disks, or hard drives.

You can typically write and debug code on a host PC using standard development tools for the PC platform, then simply copy it to and run it on the TS-2100 without modification. If additional peripherals are required, the PC/104 expansion bus allows for many standard functions available off-the-shelf. It is also very simple to create a custom PC/104 daughter board for those special features that differentiate your product. embeddedTS can provide technical support as well as a free quotation for any custom hardware, software, or BIOS modifications you may require.

Additional features include:

  • PC compatible based on Intel 386EX @ 25 MHz
    • 2 PC/AT standard serial ports
    • PC/AT standard interrupt control unit
    • PC/AT standard timer/counter unit
    • PC/AT standard Real Time Clock and CMOS
    • Watchdog timer unit
    • Synchronous serial port
  • 2 MB of DRAM
  • 1 MB Flash disk with full BIOS support
  • 16 DIO lines (IRQ capable)
  • 32 Pin JEDEC socket on-board accepts one of the following:
    • M-Systems DiskOnChip 2000 Flash Disk (8 to 144 MBytes)
    • or Battery-backed 32 KB SRAM
  • PC/104 8 bit bus
  • Rugged quick-release terminal strips used for power
  • Dimensions are 3.775" x 3.55 " (PC/104 mounting holes)
  • Power requirements are 5V DC @ 475 mA
  • Operating Temperature Range: Fanless -20° to +70°C 
  • Optional RS-485 support on COM1 (half duplex)

PC compatibility requires much more than just an x86 processor. It requires PC compatible memory and I/O maps as well as a PC compatible BIOS. The General Software EMBEDDED BIOS (Version 4.0) offers a high degree of compatibility with past and present BIOS standards allowing it to run off-the shelf operating systems and application software. This PC compatible BIOS boots to IDE Compact Flash or Drive A and the BIOS is shadowed in RAM for speed.

The TS-2000 computers are shipped, free of charge, with Embedded DOS ROM by General Software.

DOS Features

  • General Software DOS-ROM included
  • Drivers included to make the Flash disk(s) appear as a disk drive on a host system
  • Transfer files to and from the SBC with Zmodem
  • Console redirection over a serial port
  • Example programs with source code included
