data sheet 6 rev. 1.0 2016-07-15 TLE8250 high speed can transceiver functional description 4 functional description hs can is a serial bus system that connects microcon trollers, sensors and actuators for real-time control applications. the use of the controller area network (abbreviated can) within road vehicles is described by the international standard iso 11898. according to the 7-layer osi reference model the physical layer of a hs can bus system specifies the data transmission from one can node to all other available can nodes within the network. the physical layer spec ification of a can bus system incl udes all electrical and mechanical specifications of a can network. th e can transceiver is part of the ph ysical layer specif ication. several different physical layer standards of can networks have been developed in recent years. the is a high speed can transceiver without a wake- up function and defined by the international standard iso11898-2. 4.1 high speed can physical layer figure 3 high speed can bus signals and logic signals txd v cc t t v cc canh canl t v cc v diff rxd v cc t v cc = transmitter supply voltage txd = transmit data input from the microcontroller rxd = receive data output to the microcontroller canh = bus level on the canh input/output canl = bus level on the canl input/output v diff = differential voltage between canh and canl v diff = v canh C v canl dominant receiver threshold recessive receiver threshold t loop(h,l) t loop(l,h)
data sheet 7 rev. 1.0 2016-07-15 TLE8250 high speed can transceiver functional description the is a high-speed can transceive r, operating as an interface betwee n the can controller and the physical bus medium. a hs can network is a two wire, differential network which allows data transmission rates for can fd frames up to 2 mbit/s. characteristic for hs ca n networks are the two signal states on the hs can bus: dominant and recessive (see figure 3 ). v cc and gnd are the supply pins for the . the pins ca nh and canl are the interface to the hs can bus and operate in both directions, as an input and as an output. rxd and txd pins ar e the interface to the can controller, the txd pin is an input pin and the rxd pin is an output pin. the nen and nrm pins are the input pins for the mode selection (see figure 4 ). by setting the txd input pin to logica l ?low? the transmitter of the drives a dominant signal to the canh and canl pins. setting txd input to logical ?high? turns off the transm itter and the output voltage on canh and canl discharges towards the recessive level. the recess ive output voltage is provid ed by the bus-biasing (see figure 1 ). the output of the transmitter is considered to be dominant, wh en the voltage difference between canh and canl is at least higher than 1.5 v ( v diff = v canh - v canl ). parallel to the transmitte r the normal-mode receiver monitors the signal on the canh and canl pins and indicates it on the rxd output pin. a dominant signal on the canh and canl pins sets the rxd output pin to logical ?low?, vice versa a recessiv e signal sets the rxd output to lo gical ?high?. the normal-mode receiver considers a voltage difference ( v diff ) between canh and canl above 0.9 v as dominant and below 0.5 v as recessive. to be conform with hs can features, like the bit to bit arbitration, the signal on the rxd output has to follow the signal on the txd input within a defined loop delay t loop 255 ns.
data sheet 8 rev. 1.0 2016-07-15 TLE8250 high speed can transceiver functional description 4.2 modes of operation the supports three different mode s of operation, power-save mode , receive-only mode and normal- operating mode while the transceiver is supplied according to the specified functional range. the mode of operation is selected by the nen and the nrm input pins (see figure 4 ). figure 4 mode state diagram 4.2.1 normal-operating mode in normal-operating mode the tran smitter and the receiver of the hs can transceiver are active (see figure 1 ). the hs can transceiver sends the serial data stre am on the txd input pin to the can bus. the data on the can bus is displayed at the rxd pin simultaneous ly. a logical ?low? signal on the nen pin and a logical ?high? signal on the nrm pin selects the normal-ope rating mode, while the tran sceiver is supplied by v cc (see table 2 for details). 4.2.2 power-save mode the power-save mode is an idle mode of the with optimized power consumption. in power-save mode the transmitter and the normal-mode receiver are turned of f. the can not send any data to the hs can bus nor receive any data from the hs can bus. the rxd output pin is permanently ?high? in the power-save mode. a logical ?high? signal on the nen pi n selects the power-save mode, while the transceiver is supplied by the transmitter supply v cc (see table 2 for details). in power-save mode the bus input pins are not biased . therefore the canh and canl input pins are floating and the hs can bus interface has a high resistance. 4.2.3 receive-only mode in receive-only mode the normal-mode receiver is active and the transmitter is turned off. the can receive data from the hs can bus, but cannot send any data to the hs can bus. a logical ?low? signal on the nen pin and a logical ?low ? signal on the nrm pin selects the receive-only mode, while the transceiver is supplied by v cc (see table 2 for details). power-save mode nen = 0 v cc > v cc(uv,r) nen = 1 nrm = x normal-operating mode nen = 0 nrm = 1 receive-only mode nen = 0 nrm = 0 v cc > v cc(uv,r) v cc > v cc(uv,r) nrm = 0 nen = 0 nrm = 1 nen = 0 nrm = 1 nen = 1 nrm = x nen = 0 nrm = 0 nen = 1 nrm = x

data sheet 10 rev. 1.0 2016-07-15 TLE8250 high speed can transceiver functional description 4.3.1 power-down state independent of the nen and nrm input pins the is in power-down state when the transmitter supply voltage v cc is turned off (see figure 5 ). in the power-down state the input resistors of th e receiver are disconnected from the bus biasing v cc /2. the canh and canl bus interface of the is floating and acts as a high-imped ance input with a very small leakage current. the high-ohmic input does not influence th e recessive level of the can network and allows an optimized eme performance of the entire hs can network (see also table 2 ). 4.3.2 power-up the hs can transceiver powers up if the transmitter supply v cc is connected to the device. by default the device powers up in power-save mode, due to the internal pull-up resist or on the nen pin to v cc . in case the device needs to power- up to normal-operating mode, the ne n pin needs to be pulled active to logical ?low? while the nrm pin is logical ?high? (see figure 5 ).

data sheet 25 rev. 1.0 2016-07-15 TLE8250 high speed can transceiver application information 8.3 examples for mode changes ? the mode change is executed independently of the signal on the hs can bus. the canh, canl inputs may be either dominant or rece ssive. they can be also pe rmanently shorted to gnd or v cc . ? a mode change is performed independently of the signal on the txd input. the txd input may be either logical ?high? or ?low?. analog to that, changing the nen input pin to logical ?high? changes the mode of operation to the power-save mode. changing the nen input pin and the nrm input pin to logical ?low? changes the mode of operation to the receive-only mode. both mode changes are independ ent on the signals at the canh, canl and txd pins. note: in case the txd signal is ?low? setting the nrm input pin to logical ?high? and the nen input pin to logical ?low? changes the device to normal-operating mode and dr ives a dominant signal to the hs can bus?. note: the txd time-out is only effective in normal-ope rating mode. the txd time-out timer starts when the enters normal-operating mode and th e txd input is set to logical ?low?.
data sheet 26 rev. 1.0 2016-07-15 TLE8250 high speed can transceiver application information 8.3.1 mode change while th e txd signal is ?low? the example in figure 13 shows a mode change to normal-operati ng mode while the txd input is logical ?low?. the hs can signal is recessiv e, assuming all other hs can bus subs cribers are also sending a recessive bus signal. while the transceiver is in power-save mode, the tr ansmitter and the normal-mod e receiver are turned off. the drives no signal to the hs can bus nor does it re ceive any signal from the hs can bus. changing the nen to logical ?low? turns the mode of operation to normal-operating mode, while the txd input signal remains logical ?low?. the transmitter and the normal-mode rece iver remain disabled unti l the mode transition is completed. in normal-operating mo de the transceiver and the normal-m ode receiver are active. the ?low? signal on the txd input drives a dominant signal to the hs can bus and the rxd output pin becomes logical ?low?, following the dominant signal on the hs can bus. changing the mode of operation from normal-operating mode to receive-only mode by setting the nrm input pin to ?low?, disables the transmitter and the txd in put, but the normal-mode re ceiver and the rxd output remain active. the hs can bus becomes recessive since the transmitter is disabled. the rxd input indicates the recessive hs can bus signal by a logical ?h igh? output signal (s ee also the example in figure 13 ). mode changes between the power-save mode on the one side and the normal-operating mode or the receive- only mode on the other side, disable the transmitter and the normal-mode receiver. no signal can be driven to the hs can bus nor can it be re ceived from the hs can bus. mode changes betw een the normal-operating mode and the receive-only mode disable the transmitte r and the normal mode receiver remains active. the hs can transceiver monitors the hs can bus also during the mode tran sition from normal-operating mode to receive-only mode and vice versa. 8.3.2 mode change while th e bus signal is dominant the example in figure 14 shows a mode change while the bus is do minant and the txd input signal is set to logical ?high?. while the transceiver is in power-save mode, the tr ansmitter and the normal-mod e receiver are turned off. the drives no signal to the hs can bus nor does it re ceive any signal from the hs can bus. changing the nen to logical ?low? turns the mode of operation to normal-operating mode, while the txd input signal remains logical ?high?. the transmitter and th e normal-mode receiver remain disa bled until the mode transition is completed. in normal-operating mode the transceiver an d the receiver are active and therefor the rxd output changes to logical ?low? indicating th e dominant signal on the hs can bus. changing the mode of operation from normal-operating mode to receive-only mode by setting the nrm input pin to ?low?, disables the transmitter and the txd in put, but the normal-mode re ceiver and the rxd output remain active. since the dominant signal on the hs ca n bus is driven by another hs can bus subscriber, the bus remains dominant and the rxd in put indicates the dominant hs can bu s signal by a logical ?low? output signal (see also the example in figure 14 ).
