Build high performance half routers that increase the scalability and surviveability of LONWORKS control FT Router 5000 networks while lowering the overall solution cost. Configured and learning routers fall into Proven, Safe Choice a class of routers known as intelligent The FT Router 5000 IC is an Echelon routers, which use routing tables to semiconductor product that is used to build selectively forward messages based on half routers and full routers. The FT Router the destination address. 5000 IC is based on the Echelon FT 5000 Smart Transceiver and can be used to build A router configured as a bridge forwards a FT-10 channel halfrouter with LONWORKS all valid packets that match its domains, communication channel to route LonTalk whereas a router functioning as a repeater messages. An Echelon router can support forwards all valid packets. Configured installation of networks with up to routers are easily installed using an thousands of nodes. installation tool such as the OpenLNS FT Router 5000 Key Features The FT Router 5000 IC includes the Router Commissioning Tool and OpenLNS network 3.3V operation rfi mware required to implement a half operating system that calculates network router. Its compact form factor minimizes topology and layer 4 timing parameters. Higher-performance Neuron the space required to develop a half router. Core internal system clock Usage Customers can develop two half routers to scales up to 40 MHz Larger A FT Router 5000 based FT-10 channel half build a full router. Customers will need to buffer size to allow for extended- router consists of the FT Router 5000 chip, use the FT-X3 communications transformer NVs and improved throughput the FT-X3 communications transformer, to connect to the network. The Router a crystal to generate the clock and an Serial interface for inexpensive- parameters are stored in an external external memory to hold the router table. external non-volatile EEPROM EEPROM with a minimum size of 2 KB. For Two such half routers are used to build a and flash memories a full router design, customers can use the full router. A half router design that uses Compliant with TP/FT-10 same crystal and the same power supply FT Router 5000 can be used with another Channels to implement the clock needed for the two half router to function as a repeater or half routers. This offers the flexibility for Low-cost surface mount FT-X3 interface with other twisted pair physical customers to incorporate the FT Router Communications Transformer media such as RS-485, TP-78, TP-1250 or 5000 IC into their design for a higher level Compact 7mm x 7mm 48-pin LPT-11. It can also be used to implement of integration. QFN package a FT-PL router using the PL 3150 Smart The FT Router 5000 IC can use one of Transceiver. The two half routers of a full Logical Isolation between two four routing algorithms: configured router, router are logically isolated so that a failure half routers improves system learning router, bridge or repeater.

Two such half routers are used to build 5000 chip. All digital inputs are low-voltage transistor- a full router.
