For device manufacturers looking to network-enable their products, DSTni™ (Device Server Technology Network Interface) is a family of single chip solutions that allow devices, appliances and equipment to be remotely monitored and controlled over shared networks, including Ethernet and the Internet.

At Last, Everything in One Chip

All of the DSTni family members include an enhanced 80186 processor, on-chip memory, integrated peripherals, and communications controllers to support the most popular networks - including Ethernet. For simple, standalone applications, DSTni devices can be used as the primary processor in a system, in more complex applications, they can function as network coprocessors.



For basic designs, all that's needed in addition to DSTni is a couple of crystals/oscillators, a serial E²PROM, communications transceiver(s) and a power supply. With the lowest parts count design for embedded networking applications, integration complexity is minimized, resulting in rapid product development and the quickest time to market.

Since no device networking application is complete without software, we offer all of the required software and tools to speed development and reduce integration hassles. From the robust SuperTask! RTOS and comprehensive USNET TCP/IP protocol suite, that have been pre-integrated and optimized for the DSTni platform, to complementary development hardware and tools, we have everything you need.

A complete hardware and software solution for device networking - including a robust RTOS and a complete TCP/IP protocol suite.
One design supports multiple networking technologies
A single chip solution delivers higher reliability and requires less board space.
High integration minimizes project integration risk, parts count and engineering resources, speeding time to market.
Enhanced 80186 architecture leverages established x86 development tools or our integrated development environment and tool chain.
Ideal for gateways, multi-network communications adapters, and most any device that requires Ethernet networking.
