1 datasheet 3.3v radiation tolerant can transceiver, 1mbps, listen mode, split termination output isl72027seh the intersil isl72027seh is a 3.3v radiation tolerant can transceiver that is compatible with the iso11898-2 standard for applications calling for controller area network (can) serial communication in satellites and aerospace communications and telemetry data processing in harsh industrial environments. the transceiver can transmit and receive at bus speeds of up to 1mbps. the device is designed to operate over a common-mode range of -7v to +12v with a maximum of 120 nodes. the device has three discrete selectable driver rise/fall time options, a listen mode feature and a split termination output. receiver (rx) inputs feature a ?full fail-safe? design, which ensures a logic high rx output if the rx inputs are floating, shorted, or terminated but undriven. the isl72027seh is available in an 8 ld hermetic ceramic flatpack and die form that operate across the temperature range of the -55c to +125c. the logic inputs are tolerant with 5v systems. other can transceivers available are the isl72026seh and isl72028seh . for a list of differences see table 1 on page 2 . related literature ? ug051 , ?isl7202xseheval1z evaluation board user guide? ? tr018 , ?see testing of the isl72027seh can transceiver? ? tr022 , ?total dose testin g of the isl72026seh, isl72027seh and isl72028seh can transceivers? features ?dla smd 5962-15228 ? esd protection on all pins. . . . . . . . . . . . . . . . . . . . . . 4kv hbm ? compatible with iso11898-2 ? operating supply range . . . . . . . . . . . . . . . . . . . . . 3.0v to 3.6v ? bus pin fault protection to 20v ? undervoltage lockout ? cold spare: powered down devices/nodes will not affect active devices operating in parallel ? three selectable driver rise and fall times ? glitch free bus i/o during power-up and power-down ? full fail-safe (open, short, terminated/undriven) receiver ? hi z input allows for 120 nodes on the bus ? high data rates. . . . . . . . . . . . . . . . . . . . . . . . . . . . up to 1mbps ? quiescent supply current . . . . . . . . . . . . . . . . . . . . 7ma (max) ? listen mode supply current . . . . . . . . . . . . . . . . . . 2ma (max) ? -7v to +12v common-mode input voltage range ? 5v tolerant logic inputs ?thermal shutdown ? acceptance tested to 75krad(si) (ldr) wafer-by-wafer ? radiation tolerance - sel/b immune to let 60mev?cm 2 /mg - low dose rate (0.01rad(si)/s) . . . . . . . . . . . . . . 75krad(si) applications ? satellites and aerospace communications ? telemetry data processing ? high-end industrial environments ? harsh environments figure 1. typical application figure 2. fast driver and receiver waveforms 1 2 3 4 8 7 6 5 rs canh canl vref d gnd vcc r tx data in rx data out canh canl isl72027seh 0.1f vcc 0 4 0 time (1s/div) driver output (v) driver input (v) 4 0 1 2 3 receiver output (v) rs = gnd, r diff = 60 canh - canl r d november 9, 2015 fn8763.1 caution: these devices are sensitive to electrostatic discharge; follow proper ic handling procedures. 1-888-intersil or 1-888-468-3774 | copyright intersil americas llc 2015. all rights reserved intersil (and design) is a trademark owned by intersil corporation or one of its subsidiaries. all other trademarks mentioned are the property of their respective owners.

isl72027seh 10 fn8763.1 november 9, 2015 submit document feedback functional description overview the intersil isl72027seh is a 3.3v radiation tolerant can transceiver that is compatible with the iso11898-2 standard for use in can (controller area ne twork) serial communication systems. the device performs transmit and receive functions between the can controller and the can differen tial bus. it can transmit and receive at bus speeds of up to 1m bps. it is designed to operate over a common-mode range of -7v to +12v with a maximum of 120 nodes. the device is capabl e of withstanding 20v on the canh and canl bus pins outside of ion beam and 16v under ion beam. slope adjustment the output driver rise and fall ti me has three distinct selections that may be chosen by using a resistor from the rs pin to gnd. connecting the rs pin directly to gnd results in output switching times that are the fastest, limited only by the drive capability of the output stage. rs = 10k provides for a typical slew rate of 8v/s and rs = 50k provides for a typical slew rate of 4v/s. putting a high logic level to the rs pin places the device in a low current listen mode. the protocol controller uses this mode to switch between low power listen mode and a normal transmit mode. cable length the device can work per iso11898 specification with a 40m cable and stub length of 0.3m and 60 nodes at 1mbps. this is greater than the iso requiremen t of 30 nodes. the cable type specified is a twisted pair (shielded or unshielded) with a characteristic impedance of 120 . resistors equal to this are to be terminated at both ends of the cable. stubs should be kept as short as possible to prevent reflections. cold spare high reliability system de signers implementing data communications have to be sensitive to the potential for single point failures. to mitigate the risk of a failure they will use redundant bus transceivers in parallel. space systems call for high reliability in data commun ications that are resistant to single point failures. this is achieved by using a redundant bus transceiver in parallel. in this arrangement, both active and quiescent devices can be present simultaneously on the bus. the quiescent devices are powered down for cold spare and do not affect the communication of the other active nodes. to achieve this, a powered down transceiver (v cc < 200mv) has a resistance between the vref pin or the canh pin or canl pin and the v cc supply rail of >480k (max) with a typical resistance >2m . the resistance between canh and canl of a powered down transceiver has a typical resistance of 80k . listen mode when a high level is applied to the rs pin, the device enters a low power listen mode. the driver of the transceiver is switched off to conserve power while the receiver remains active. in listen mode the transceiver draws 2ma (max) of current. a low level on the rs pin brings the device back to normal operation. using 3.3v devices in 5v systems looking at the differential volt age of both the 3.3v and 5v devices, the differential voltage is the same, the recessive common-mode output is the same. the dominant common-mode output voltage is slightly lower than the 5v counterparts. the receiver specs are also the same. though the electrical parameters appear co mpatible, it is advised that necessary system testing be perf ormed to verify interchangeable operation. split mode termination the vref pin provides a v cc /2 output voltage for split mode termination. the vref pin has the same esd protection, short-circuit protection, and common-mode operating range as the bus pins. the split mode terminatio n technique is shown in figure 19 . it is used to stabilize the bus voltage at v cc /2 and prevent it from drifting to a high common-mod e voltage during periods of inactivity. the technique improves the electromagnetic compatibility of a network. the split mode termination is put at each end of the bus. the c l capacitor between the two 60 resistors filters unwanted high frequency noise to ground . the resistors should have a tolerance of 1% or better and the two resistors should be carefully matched to provide the most effective emi immunity. a typical value of c l for a high speed can network is 4.7nf, which generates a 3db point at 1.1mbps. the capacitance value used is dependent on the signaling rate of the network. figure 19. split termination node #1 node #n canh canl vref vref c l c l node #2 60 60 60 60
