proven, safe choice the ft router 5000 ic is an echelon semiconductor product that is used to build half routers and full routers. the ft router 5000 ic is based on the echelon ft 5000 smart transceiver and can be used to build a ft-10 channel halfrouter with l on w orks ? communication channel to route lontalk ? messages. an echelon router can support installation of networks with up to thousands of nodes. the ft router 5000 ic includes the router frmware 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. customers will need to use the ft-x3 communications transformer to connect to the network. the router parameters are stored in an external eeprom with a minimum size of 2 kb. for a full router design, customers can use the same crystal and the same power supply to implement the clock needed for the two half routers. this offers the fexibility for customers to incorporate the ft router 5000 ic into their design for a higher level of integration. the ft router 5000 ic can use one of four routing algorithms: confgured router, learning router, bridge or repeater. the ability to choose these options allows the customer to trade off system performance for ease of installation. confgured 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 router confgured as a bridge forwards all valid packets that match its domains, whereas a router functioning as a repeater forwards all valid packets. confgured routers are easily installed using an installation tool such as the openlns commissioning tool and openlns network operating system that calculates network topology and layer 4 timing parameters. usage a ft router 5000 based ft-10 channel half router consists of the ft router 5000 chip, the ft-x3 communications transformer, a crystal to generate the clock and an external memory to hold the router table. two such half routers are used to build a full router. a half router design that uses ft router 5000 can be used with another half router to function as a repeater or interface with other twisted pair physical media such as rs-485, tp-78, tp-1250 or lpt-11. it can also be used to implement a ft-pl router using the pl 3150 smart transceiver. the two half routers of a full router are logically isolated so that a failure in one half router will not affect the other sides network. www.echelon.com ft router 5000 build high performance half routers that increase the scalability and surviveability of l on w orks ? control networks while lowering the overall solution cost. ft router 5000 key features ? 3.3v operation ? higher-performance neuron ? core; internal system clock scales up to 40 mhz; larger buffer size to allow for extended - nvs and improved throughput ? serial interface for inexpensive - external non-volatile eeprom and fash memories ? compliant with tp/ft-10 channels ? low-cost surface mount ft-x3 communications transformer ? compact 7mm x 7mm 48-pin qfn package ? logical isolation between two half routers improves system reliability by isolating failures between channels ? -40c to +85c operating temperature range
a ft router 5000 ic based l on w orks half router consists of the ft router 5000 ic, the ft-x3 communications transformer, a crystal to generate the clock and an external serial memory to hold the router table. two such half routers are used to build a full router. a half router design that uses ft router 5000 can be used with a half router that uses the router 5000 and an external transceiver such as rs-485, tp-1250, tp-78, ftt- 10a or lpt-11 to implement a l on w orks full router. the ft router 5000 ic can also be used to implement the ft section of a ftpl router along with the pl 3150 smart transceiver to implement the pl section. additionally, the ft router 5000 ic offers higher reliability since two half routers of a full router are logically isolated and a failure in one half router will not affect the other sides network. l on w orks application programs do not have to be modifed to work with routers. only the network confguration of a device has to be modifed when a device is moved to the far side of a router. the required modifcations to the network confguration 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 confguration is automatically managed by network server tools based on openlns. monitoring and control applications, such as those based on the lca object server ocx, do not require modifcations to work with multi-channel networks when routers are used. all network confguration is performed over the installed network, further minimizing installation and maintenance costs because routers do not have to be physically accessed to change their confguration. figure 1: block diagram of the l on w orks router based on the ft router 5000 figure 2: ft router 5000 chip pinout table 1: ft router 5000 chip pin assignments below is a table of the pin assignments for the ft router 5000 chip. all digital inputs are low-voltage transistor- transistor logic (lvttl) compatible, 5 v tolerant, with low leakage. all digital inputs are low-voltage transistortransistor logic (lvttl) compatible, low leakage, 5v-tolerant. all digital outputs are slew-rate limited to reduce electromagnetic interference (emi). name pin number type description svc~ 1 digital i/o service (active low) io0 2 digital i/o io0 (side a to side b) io1 3 digital i/o io1 (side a to side b) io2 4 digital i/o io2 (side a to side b) io3 5 digital i/o io3 (side a to side b) vdd1v8 6 power 1.8 v power input (from internal voltage regulator) io4 7 digital i/o io4 (side a to side b) vdd3v3 8 power 3.3 v power io5 9 digital i/o io5 (side a to side b) io6 10 digital i/o io6 (side a to side b) io7 11 digital i/o io7 (side a to side b) io8 12 digital i/o io8 (side a to side b) io9 13 digital i/o io9 (side a to side b) io10 14 digital i/o io10 (side a to side b) io11 15 digital i/o io11 (not used for routers) vdd1v8 16 power 1.8 v power input (from internal voltage regulator) trst~ 17 digital input jtag test reset (active low) vdd3v3 18 power 3.3 v power tck 19 digital input jtag test clock tms 20 digital input jtag test mode select tdi 21 digital input jtag test data in tdo 22 digital output jtag test data out xin 23 oscillator in crystal oscillator input xout 24 oscillator out crystal oscillator output vddpll 25 power 1.8 v power input (from internal voltage regulator) gndpll 26 power ground vout1v8 27 power 1.8 v power output (of internal voltage regulator) rst~ 28 digital i/o reset (active low) vin3v3 29 power 3.3 v power input vdd3v3 30 power 3.3 v power avdd3v3 31 power 3.3 v power netn 32 comm network port (polarity insensitive) agnd 33 ground ground netp 34 comm network port (polarity insensitive) ft 5000 smart tr ansceiver 1 2 3 4 5 6 7 8 9 10 11 12 36 35 34 33 32 31 30 29 28 27 26 25 gnd nc netp agnd netn av dd3v3 vdd3v3 vin3v3 rst~ vout1v8 gndpll vddpll gnd pa d dashed line represents pad (pin 49) pad must be connected to gnd svc~ io0 io1 io2 io3 vdd1v8 io4 vdd3v3 io5 io6 io7 io8 13 14 15 16 17 18 19 20 21 22 23 24 io9 io10 io1 1 vdd1v8 trst~ vdd3v3 tck tms tdi tdo xin xout 48 47 46 45 44 43 42 41 40 39 38 37 mosi sck miso scl vdd1v8 sda_cs1~ vdd3v3 vdd3v3 cs0~ cp4 rxon txon ft router 5000 ft router 5000 ft router 5000
