14315R-100

The Router 5000 chip is used to build high performance half-routers that increase the scalability and surviveability of LONWORKS® control networks and lower installation costs by allowing mixed physcial media to be used in a single installation. Router 5000 Model 14315R-100 Based on the Neuron® 5000 core, the Router 5000 provides the design flexibility to interface to the external transceiver of your choice for building a LONWORKS communication channel. FEATURES • 3.3V operation. • Higher Performance — Clock rate up to 40 MHz — Larger buffer size to allow for extended NVs and improved throughput. • Transceiver-independent design. • Compact 7mm x 7mm 48-pin QFN package. • Can be connected to a transceiver running at any LonWorks® bit rate from 610 bps to 1.25Mbps. • Logical Isolation between two half-routers improves system reliability by isolating failures between channels. • Transparent multi-channel and multi-media support. • -40°C to +85°C operating temperature range. The Router 5000 includes the Router firmware required to implement a half-router. Its compact form factor minimizes the space required to develop a half-router. Customers can develop two half-routers to build a full router with the same or different external transceiver types. Commonly used transceiver types include support for TP/FT-10, TP-RS485, TP/XF-78F, TP/XF-1250 channel types and the LPT-11 transceiver. These external transceivers can run at interface bit rates from 9.8 kbps to 1.25 Mbps. The Router parameters can be stored in an external EEPROM with a maximum size of 2 KB. Customers will need to specify router parameters that are applicable for the external transceiver type used with the Router 5000. For a full router design, customers can use the same crystal and the same power supply to implement the clock and power supply needed for the two half-routers, which helps minimize the overall size needed to implement a full router. A Router 5000 can use one of four routing algorithms: Configured router, Learning router, Bridge or Repeater. The ability to choose these options allows the customer to trade off system performance for ease of installation. Configured and Learning routers fall into a class of routers known as intelligent routers, which use routing tables to selectively forward messages based on the destination address. A Bridge 1 forwards all valid packets that match its domains, whereas a Repeater forwards all valid packets. Configured routers are easily installed using an installation tool that calculates network topology and layer 4 timing parameters, such as the LonMaker® Integration Tool or an installation tool based on the LNS® network operating system. Usage A half-router consists of the Router 5000 chip and an external transceiver along with a crystal to generate the clock and an external memory to hold the router table. Any type of external transceiver can be used with the Router 5000, such as a TP/FT-10, TP-RS485, TP/XF78, TP/XF-1250 or LPT-11 transceiver. The Router 5000 is compatible with all LonWorks transceivers, including standard transceivers for free topology, link power, twisted pair, and power line. Using multiple communications media can minimize installation costs and increase system performance by allowing easily installed media, such as power line or link power, to be combined with media such as TP/XF-1250 twisted pair. The two half-routers of a full router are logically isolated so that a failure in one half-router will not affect the other. MOSI SCK MISO SCL VDD1V8 SDA_CS1~ VDD3V3 VDD3V3 CS0~ CP4 CP3 CP2 48 47 46 45 44 43 42 41 40 39 38 37 Router 5000 Pin Configuration Pin Name 1 36 GND IO0 2 35 NC IO1 3 34 CP1 IO2 4 33 AGND IO3 5 32 CP0 VDD1V8 6 31 AVDD3V3 IO4 7 30 VDD3V3 VDD3V3 8 29 VIN3V3 IO5 9 28 RST~ IO6 10 27 VOUT1V8 IO7 11 26 GNDPLL IO8 12 25 VDDPLL 13 14 15 16 17 18 19 20 21 22 23 24 IO9 IO10 IO11 VDD1V8 TRST~ VDD3V3 TCK TMS TDI TDO XIN XOUT Dashed line represents Pad (pin 49) Pad must be connected to GND Figure 2: Router 5000 Pinout Router 5000 Chip Pin Assignments Pin Name Figure 1: Block Diagram of a LONWORKS Router Based on the Router 5000 LonWorks application programs do not have to be modified to work with routers. Only the network configuration of a device has to be modified when a device is moved to the far side of a router. The required modifications to the network configuration can be done automatically by an installation tool. Routers are also independent of the network variables and message tags in a system, and can forward an unlimited number of them, which saves development cost because no code development is required to use routers in a system. It also saves installation and maintenance costs because router configuration is automatically managed by network server tools based on LNS Server. Monitoring and Control Applications, such as those based on the LCA Object Server OCX, do not require modifications to work with multi-channel networks when routers are used. All network configuration is performed over the installed network, further minimizing installation and maintenance costs because routers do not have to be physically accessed to change their configuration.
