6 Funcional Descripion 4 Funcional Descripion HS CAN is a serial bus sysem ha connecs microconrollers, sensors and acuaors for real-ime conrol applicaions. The use of he Conroller Area Nework (abbreviaed CAN) wihin road vehicles is described by he inernaional sandard ISO According o he 7-layer OSI reference model he physical layer of a HS CAN bus sysem specifies he daa ransmission from one CAN node o all oher available CAN nodes wihin he nework. The physical layer specificaion of a CAN bus sysem includes all elecrical and mechanical specificaions of a CAN nework. The CAN ransceiver is par of he physical layer specificaion. Several differen physical layer sandards of CAN neworks have been developed in recen years. The is a High Speed CAN ransceiver wihou a wake-up funcion and defined by he inernaional sandard ISO High Speed CAN Physical Layer TxD CANH CANL VCC VCC VCC = Transmier supply volage TxD = Transmi daa inpu from he microconroller RxD = Receive daa oupu o he microconroller CANH = Bus level on he CANH inpu/oupu CANL = Bus level on he CANL inpu/oupu VDiff = Differenial volage beween CANH and CANL VDiff = VCANH VCANL VDiff VCC dominan receiver hreshold recessive receiver hreshold RxD VCC Loop(H,L) Loop(L,H) Figure 3 High speed CAN bus signals and logic signals Daa Shee 6 Rev. 1.0

7 Funcional Descripion The is a High-Speed CAN ransceiver, operaing as an inerface beween he CAN conroller and he physical bus medium. A HS CAN nework is a wo wire, differenial nework which allows daa ransmission raes for CAN FD frames up o 2 MBi/s. Characerisic for HS CAN neworks are he wo signal saes on he HS CAN bus: dominan and recessive (see Figure 3). V CC and GND are he supply pins for he. The pins CANH and CANL are he inerface o he HS CAN bus and operae in boh direcions, as an inpu and as an oupu. RxD and TxD pins are he inerface o he CAN conroller, he TxD pin is an inpu pin and he RxD pin is an oupu pin. The NEN and NRM pins are he inpu pins for he mode selecion (see Figure 4). By seing he TxD inpu pin o logical low he ransmier of he drives a dominan signal o he CANH and CANL pins. Seing TxD inpu o logical high urns off he ransmier and he oupu volage on CANH and CANL discharges owards he recessive level. The recessive oupu volage is provided by he bus-biasing (see Figure 1). The oupu of he ransmier is considered o be dominan, when he volage difference beween CANH and CANL is a leas higher han 1.5 V (V Diff = V CANH - V CANL ). Parallel o he ransmier he normal-mode receiver moniors he signal on he CANH and CANL pins and indicaes i on he RxD oupu pin. A dominan signal on he CANH and CANL pins ses he RxD oupu pin o logical low, vice versa a recessive signal ses he RxD oupu o logical high. The normal-mode receiver considers a volage difference (V Diff ) beween CANH and CANL above 0.9 V as dominan and below 0.5 V as recessive. To be conform wih HS CAN feaures, like he bi o bi arbiraion, he signal on he RxD oupu has o follow he signal on he TxD inpu wihin a defined loop delay Loop 255 ns. Daa Shee 7 Rev. 1.0

8 Funcional Descripion 4.2 Modes of Operaion The suppors hree differen modes of operaion, power-save mode, receive-only mode and normaloperaing mode while he ransceiver is supplied according o he specified funcional range. The mode of operaion is seleced by he NEN and he NRM inpu pins (see Figure 4). V CC > V CC(UV,R) power-save mode NEN = 0 NRM = 1 NEN = 1 NRM = X NEN = 1 NRM = X NEN = 1 NRM = X NEN = 0 NRM = 0 normal-operaing mode NEN = 0 NRM = 1 NEN = 0 NRM = 0 NEN = 0 NRM = 1 receive-only mode NEN = 0 NRM = 0 Figure 4 V CC > V CC(UV,R) Mode sae diagram V CC > V CC(UV,R) Normal-operaing Mode In normal-operaing mode he ransmier and he receiver of he HS CAN ransceiver are acive (see Figure 1). The HS CAN ransceiver sends he serial daa sream on he TxD inpu pin o he CAN bus. The daa on he CAN bus is displayed a he RxD pin simulaneously. A logical low signal on he NEN pin and a logical high signal on he NRM pin selecs he normal-operaing mode, while he ransceiver is supplied by V CC (see Table 2 for deails) Power-save Mode The power-save mode is an idle mode of he wih opimized power consumpion. In power-save mode he ransmier and he normal-mode receiver are urned off. The can no send any daa o he HS CAN bus nor receive any daa from he HS CAN bus. The RxD oupu pin is permanenly high in he power-save mode. A logical high signal on he NEN pin selecs he power-save mode, while he ransceiver is supplied by he ransmier supply V CC (see Table 2 for deails). In power-save mode he bus inpu pins are no biased. Therefore he CANH and CANL inpu pins are floaing and he HS CAN bus inerface has a high resisance Receive-only Mode In receive-only mode he normal-mode receiver is acive and he ransmier is urned off. The can receive daa from he HS CAN bus, bu canno send any daa o he HS CAN bus. A logical low signal on he NEN pin and a logical low signal on he NRM pin selecs he receive-only mode, while he ransceiver is supplied by V CC (see Table 2 for deails). Daa Shee 8 Rev. 1.0

9 Funcional Descripion 4.3 Power-up and Undervolage Condiion By deecing an undervolage even or by swiching off he ransmier power supply V CC, he ransceiver changes he mode of operaion (deails see Figure 5).

10 Funcional Descripion Power-down Sae Independen of he NEN and NRM inpu pins he is in power-down sae when he ransmier supply volage V CC is urned off (see Figure 5). In he power-down sae he inpu resisors of he receiver are disconneced from he bus biasing V CC /2. The CANH and CANL bus inerface of he is floaing and acs as a high-impedance inpu wih a very small leakage curren. The high-ohmic inpu does no influence he recessive level of he CAN nework and allows an opimized EME performance of he enire HS CAN nework (see also Table 2) Power-up The HS CAN ransceiver powers up if he ransmier supply V CC is conneced o he device. By defaul he device powers up in power-save mode, due o he inernal pull-up resisor on he NEN pin o V CC. In case he device needs o power-up o normal-operaing mode, he NEN pin needs o be pulled acive o logical low while he NRM pin is logical high (see Figure 5). Daa Shee 10 Rev. 1.0

11 Funcional Descripion Undervolage on he Transmier Supply V CC In case he ransmier supply V CC falls below he hreshold V CC < V CC(UV,F), he ransceiver can no provide he correc bus levels o he CANH and CANL anymore. The normal-mode receiver is powered by he ransmier supply V CC. In case of insufficien V CC supply he can neiher ransmi he CANH and CANL signals correcly o bus nor can i receive hem properly. Therefore he powers down and blocks boh, he ransmier and he receiver. The ransceiver powers up again, when he ransmier supply V CC recovers from he undervolage condiion.

12 Fail Safe Funcions 5 Fail Safe Funcions 5.1 Shor Circui Proecion The CANH and CANL bus oupus are shor circui proof, eiher agains GND or a posiive supply volage. A curren limiing circui proecs he ransceiver agains damages. If he device is heaing up due o a coninuous shor on he CANH or CANL, he inernal overemperaure proecion swiches off he bus ransmier. 5.2 Unconneced Logic Pins All logic inpu pins have an inernal pull-up resisor o V CC. In case he V CC supply is acivaed and he logical pins are open, he eners ino he power-save mode by defaul. In power-save mode he ransmier of he is disabled and he bus bias is floaing. 5.3 TxD Time-ou Funcion The TxD ime-ou feaure proecs he CAN bus agains permanen blocking in case he logical signal on he TxD pin is coninuously low. A coninuous low signal on he TxD pin migh have is roo cause in a lockedup microconroller or in a shor circui on he prined circui board, for example. In normal-operaing mode, a logical low signal on he TxD pin for he ime > TxD enables he TxD ime-ou feaure and he disables he ransmier (see Figure 7). The receiver is sill acive and he daa on he bus coninues o be moniored by he RxD oupu pin. CANH CANL > TxD TxD ime-ou TxD ime ou released TxD RxD Figure 7 TxD ime-ou funcion Figure 7 illusraes how he ransmier is deacivaed and acivaed again. A permanen low signal on he TxD inpu pin acivaes he TxD ime-ou funcion and deacivaes he ransmier. To release he ransmier afer a TxD ime-ou even he requires a signal change on he TxD inpu pin from logical low o logical high. Daa Shee 12 Rev. 1.0

The overemperaure proecion is acive in normal-operaing mode and disabled in power-save mode and receive-only mode. In case of an overemperaure condiion, he emperaure sensor will disable he ransmier (see Figure 1) while he ransceiver remains in normal-operaing mode. Afer he device has cooled down he ransmier is acivaed again (see Figure 8). A hyseresis is implemened wihin he emperaure sensor.

Depending on he seleced mode of operaion, he RxD oupu pin is se o logical high during he mode change. In his case he RxD oupu does no reflec he saus on he CANH and CANL inpu pins (see as an example Figure 12 and Figure 13). Daa Shee 13 Rev. 1.0

25 Applicaion Informaion 8.3 Examples for Mode Changes The mode change is execued independenly of he signal on he HS CAN bus. The CANH, CANL inpus may be eiher dominan or recessive. They can be also permanenly shored o GND or V CC. A mode change is performed independenly of he signal on he TxD inpu. The TxD inpu may be eiher logical high or low. Analog o ha, changing he NEN inpu pin o logical high changes he mode of operaion o he power-save mode. Changing he NEN inpu pin and he NRM inpu pin o logical low changes he mode of operaion o he receive-only mode. Boh mode changes are independen on he signals a he CANH, CANL and TxD pins. Noe: Noe: In case he TxD signal is low seing he NRM inpu pin o logical high and he NEN inpu pin o logical low changes he device o normal-operaing mode and drives a dominan signal o he HS CAN bus. The TxD ime-ou is only effecive in normal-operaing mode. The TxD ime-ou imer sars when he eners normal-operaing mode and he TxD inpu is se o logical low. Daa Shee 25 Rev. 1.0

26 Applicaion Informaion Mode Change while he TxD Signal is low The example in Figure 13 shows a mode change o normal-operaing mode while he TxD inpu is logical low. The HS CAN signal is recessive, assuming all oher HS CAN bus subscribers are also sending a recessive bus signal. While he ransceiver is in power-save mode, he ransmier and he normal-mode receiver are urned off. The drives no signal o he HS CAN bus nor does i receive any signal from he HS CAN bus. Changing he NEN o logical low urns he mode of operaion o normal-operaing mode, while he TxD inpu signal remains logical low. The ransmier and he normal-mode receiver remain disabled unil he mode ransiion is compleed. In normal-operaing mode he ransceiver and he normal-mode receiver are acive. The low signal on he TxD inpu drives a dominan signal o he HS CAN bus and he RxD oupu pin becomes logical low, following he dominan signal on he HS CAN bus. Changing he mode of operaion from normal-operaing mode o receive-only mode by seing he NRM inpu pin o low, disables he ransmier and he TxD inpu, bu he normal-mode receiver and he RxD oupu remain acive. The HS CAN bus becomes recessive since he ransmier is disabled. The RxD inpu indicaes he recessive HS CAN bus signal by a logical high oupu signal (see also he example in Figure 13). Mode changes beween he power-save mode on he one side and he normal-operaing mode or he receiveonly mode on he oher side, disable he ransmier and he normal-mode receiver. No signal can be driven o he HS CAN bus nor can i be received from he HS CAN bus. Mode changes beween he normal-operaing mode and he receive-only mode disable he ransmier and he normal mode receiver remains acive. The HS CAN ransceiver moniors he HS CAN bus also during he mode ransiion from normal-operaing mode o receive-only mode and vice versa Mode Change while he Bus Signal is dominan The example in Figure 14 shows a mode change while he bus is dominan and he TxD inpu signal is se o logical high. While he ransceiver is in power-save mode, he ransmier and he normal-mode receiver are urned off. The drives no signal o he HS CAN bus nor does i receive any signal from he HS CAN bus. Changing he NEN o logical low urns he mode of operaion o normal-operaing mode, while he TxD inpu signal remains logical high. The ransmier and he normal-mode receiver remain disabled unil he mode ransiion is compleed. In normal-operaing mode he ransceiver and he receiver are acive and herefor he RxD oupu changes o logical low indicaing he dominan signal on he HS CAN bus. Changing he mode of operaion from normal-operaing mode o receive-only mode by seing he NRM inpu pin o low, disables he ransmier and he TxD inpu, bu he normal-mode receiver and he RxD oupu remain acive. Since he dominan signal on he HS CAN bus is driven by anoher HS CAN bus subscriber, he bus remains dominan and he RxD inpu indicaes he dominan HS CAN bus signal by a logical low oupu signal (see also he example in Figure 14).
