IPv6 on an 8-bit microcontroller

InternetNode and Yokogawa Electric demonstrated the capability of an IPv6 system at the recent Networld+Interop 2001.

InternetNode and Yokogawa Electric Corporation demonstrated the capability of an IPv6 system at the recent Networld+Interop 2001by connecting over one hundred of their ‘HotNode’ temperature sensing micronodes to an exhibition network.

The next-generation Internet protocol, IPv6 provides virtually unlimited IP addresses, network security, and plug-and-play network connection capability. In Japan, IPv6-based commercial services are now becoming available.

‘HotNode’ is an IPv6-enabled exhibit model that uses Dallas Semiconductor’s DS-TINI-1 microcontroller, an embedded microcontroller with IPv6 connectivity jointly implemented at InternetNode, Yokogawa, and Dallas.

IPv6 has a 128-bit address space, allowing for a virtually unlimited number of nodes to connect directly to the Internet. A compact embedded microcontroller with IPv6 connectivity is needed to allow appliance and equipment manufacturers to design products for new applications and markets.

InternetNode and Yokogawa chose the DS-TINI-1 microcontroller from Dallas because of its low cost and underlying support of Internet technologies. InternetNode has jointly integrated an IPv6 stack into Dallas’s TINI runtime environment for network microcontrollers.

Editors note: Tiny InterNet Interface (TINI) is a platform developed by Dallas Semiconductor to provide system designers and software developers with a means to design a wide variety of hardware devices able to connect directly to corporate and home networks.

The platform is a combination of a small chipset and a Java-programmable runtime environment. The chipset provides processing, control, device-level communication and networking capabilities. The features of the underlying hardware are exposed to the software developer through a set of Java application programming interfaces.

The primary objective of the TINI platform is to give everything from small sensors and actuators to factory automation equipment and legacy hardware a voice on the network. This allows the devices to be monitored, controlled and managed remotely. The combination of I/O capability, a TCP/IP network protocol stack and an object-oriented programming environment empowers programmers to create applications that provide not only local control of, but also the ability to remotely manage, TINI-based devices.

TINI’s networking capability extends the connectivity of any attached device by allowing interaction with remote systems and users through standard network applications such as Web browsers.
