Overview

Overview

The µFlashTCP-EP single board computer is based on the Intel 386Ex microcomputer. The
386Ex is a high performance, 32-bit, single-chip microcomputer that is software compatible with
the Intel 80386 family of microprocessors. Onboard Ethernet provides a direct connection to
10BASE-T networks. DOS compatibility allows development in a familiar environment with a
wide range of tools. High endurance flash memory eliminates EPROM programming without
worry of damaging the onboard non-volatile memory with repeated program cycles. Applications
are uploaded directly into the flash disk.  Expansion options provide high capacity flash storage
eliminating the size and reliability problems associated with electro-mechanical storage devices.

Software development for the µFlashTCP-EP is remarkably simple and quick. Programs are
written on a PC compatible computer in the language of your choice. After your application has
been compiled or assembled and linked into .EXE or .COM form, it is uploaded to the
µFlashTCP-EP’s flash disk with your favorite telecommunications program using the X-Modem
protocol. The application can then be tested and debugged through the console serial port. When
the application is running to your satisfaction, the startup batch file can be modified so that the
application will load and execute upon reset or powerup.

These features yield a quick and cost effective solution for applications such as networking,
embedded web and serial protocol conversion.
