Indusrial High Speed CAN-FD Transceiver Overview of he CANH and CANL signals, he IFX1051 provides a very low level of elecromagneic emission (EME) wihin a wide frequency range. The IFX1051 is available in a small, leadless PG-TSON-8 package as well as in a sandard PG-DSO-8 package. The packages are RoHS complian and halogen free and moreover suppor he solder join requiremens for auomaed opical inspecion (AOI). The IFX1051 is fulfilling or exceeding he requiremens of he ISO11898-2. The IFX1051 provides a digial supply inpu V IO ha allows direc inerfacing o 3.3 V microconrollers and in addiion offers a Receive-only mode. One key feaure of he IFX1051 is ha i fulfills he enhanced physical layer requiremens for CAN FD (CAN wih Flexible Daa Rae) and suppors daa raes up o 2 MBi/s. This allows he usage of he IFX1051 in neworks using CAN FD proocol nex o all indusrial CAN applicaions using he classical proocol. CAN FD based neworks offer a considerably increased bandwidh compared o classical CAN proocol because i allows increased daa birae in combinaion wih increased payload per message and hus making CAN FD a powerful and fuure-oriened alernaive for all exising CAN applicaions whenever bandwidh limiaions become an issue. On he basis of a very low leakage curren on he HS CAN bus inerface he IFX1051 provides an excellen passive behavior in power-down sae. These and oher feaures make he IFX1051 excepionally suiable for mixed supply HS CAN neworks. In addiion he IFX1051 provides excellen ESD immuniy ogeher wih a very high elecromagneic immuniy (EMI). Moreover he IFX1051 is equipped wih a TxD ime-ou funcionaliy which proecs he CAN bus from being blocked if he ransceiver receives by error a permanen low level signal on TxD from is conroller. The implemenaion of his funcionaliy wih a very long delay iming of > 4.5 ms allows a he same ime he usage of he device in physically very long bus neworks as hey can be found in many indusrial applicaions. The wo differen operaing modes - Normal mode and Receive-only mode, is addiional fail-safe feaures like TxD ime-ou bu as well he CAN FD capabiliy and opimized oupu slew raes on he CANH and CANL signals make he IFX1051 an ideal choice for large HS CAN neworks wih demand for high daa ransmission raes. The qualificaion of his produc is based on JEDEC JESD47 and may reference exising qualificaion resuls of similar producs. Such referring is jusified by he srucural similariy of he producs.

Indusrial High Speed CAN-FD Transceiver 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) is described by he inernaional sandard ISO 11898. 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 IFX1051 is a High Speed CAN ransceiver wihou a wake-up funcion and defined by he inernaional sandard ISO 11898-2. 4.1 High Speed CAN Physical Layer TxD CANH CANL V IO V CC V IO = Digial supply volage V CC = 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 V Diff = Differenial volage beween CANH and CANL V Diff = V CANH V CANL V Diff V CC dominan receiver hreshold recessive receiver hreshold RxD V IO Loop(H,L) Loop(L,H) Figure 3 High speed CAN bus signals and logic signals Daa Shee 6 Rev. 1.0

Indusrial High Speed CAN-FD Transceiver Funcional Descripion The IFX1051 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 bus nework which allows daa ransmission raes for CAN FD frames up o 2 MBi/s. Main characerisics for HS CAN neworks are he wo signal saes on he HS CAN bus: dominan and recessive (see Figure 3). V CC, V IO and GND are he supply pins for he IFX1051. 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 RM pin is he inpu pin for he mode selecion (see Figure 4). By seing he TxD inpu pin o logical low he ransmier of he IFX1051 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. The hresholds of he digial inpus (TxD and RM) and also he RxD oupu volage are adaped o he digial power supply V IO. Daa Shee 7 Rev. 1.0

Indusrial High Speed CAN-FD Transceiver Funcional Descripion 4.2 Modes of Operaion The IFX1051 suppors wo differen modes of operaion, receive-only mode and normal-operaing mode while he ransceiver is supplied according o he specified funcional range. The mode of operaion is seleced by he RM inpu pin (see Figure 4). V CC > V CC(UV) V IO > V IO(UV,R) receive-only mode RM = 1 RM = 0 RM = 1 V CC > V CC(UV,R) V IO > V IO(UV,R) normal-operaing mode RM = 0 Figure 4 Mode sae diagram 4.2.1 Normal-operaing Mode In normal-operaing mode he ransmier and he receiver of he HS CAN ransceiver IFX1051 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 RM pin selecs he normal-operaing mode, while he ransceiver is supplied by V CC and V IO (see Table 2 for deails). 4.2.2 Receive-only Mode In receive-only mode he normal-mode receiver is acive and he ransmier is urned off. The IFX1051 can receive daa from he HS CAN bus, bu canno send any daa o he HS CAN bus. A logical high signal on he RM pin selecs he receive-only mode, while he ransceiver is supplied by V CC and V IO (see Table 2 for deails). Daa Shee 8 Rev. 1.0

Indusrial High Speed CAN-FD Transceiver Funcional Descripion 4.3 Power-up and Undervolage Condiion By deecing an undervolage even, eiher on he ransmier supply V CC or he digial supply V IO, he ransceiver IFX1051 changes he mode of operaion. When he digial power supply V IO is swiched off, he ransceiver powers down and remains in he power-down sae. When swiching off he ransmier supply V CC, he ransceiver changes o he forced power-save mode, (deails 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 IFX1051 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). Daa Shee 9 Rev. 1.0

Indusrial High Speed CAN-FD Transceiver Funcional Descripion 4.3.2 Forced Power-save Mode The forced power-save mode is a fail-safe mode o avoid any disurbance on he HS CAN bus, while he IFX1051 faces a loss of he ransmier supply V CC. In forced power-save mode, he ransmier and he normal-mode receiver are urned off and herefore he ransceiver IFX1051 can no disurb he bus media. The RxD oupu pin is permanenly se o logical high. The bus biasing is floaing (deails see Table 2). The forced power-save mode can only be enered when he ransmier supply V CC is no available, eiher by powering up he digial supply V IO only or by urning off he ransmier supply in normal-operaing mode or in receive-only mode (see Figure 5). While he ransceiver IFX1051 is in forced power-save mode he RM pin is disabled. 4.3.3 Power-up The HS CAN ransceiver IFX1051 powers up if a leas he digial supply V IO is conneced o he device. By defaul he device powers up in normal-operaing mode, due o he inernal pull-down resisor on he RM pin o GND. In case he device needs o power-up in receive-only mode, he RM pin needs o be pulled acive o logical high and he supplies V IO and V CC have o be conneced. By supplying only he digial power supply V IO he IFX1051 powers up in forced power-save mode (see Figure 5). 4.3.4 Undervolage on he Digial Supply V IO If he volage on V IO supply inpu falls below he hreshold V IO < V IO(U,F), he ransceiver IFX1051 powers down and changes o he power-down sae. ransmier supply volage VCC = don care VIO VIO undervolage monior VIO(UV,F) hyseresis VIO(UV,H) VIO undervolage monior VIO(UV,R) Delay(UV) delay ime undervolage any mode of operaion power-down sae normal-operaing mode RM X = don care low due he inernal pull-down resisor 1) 1) assuming no exernal signal applied Figure 6 Undervolage on he digial supply V IO Daa Shee 10 Rev. 1.0

Indusrial High Speed CAN-FD Transceiver Funcional Descripion 4.3.5 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 IFX1051 changes he mode of operaion o forced power-save mode. The ransmier and also he normal-mode receiver of he IFX1051 are powered by he V CC supply. In case of an insufficien V CC supply, he IFX1051 can neiher ransmi he CANH and CANL signals correcly o he bus, nor can i receive hem properly. Therefore he IFX1051 blocks he ransmier and he receiver in forced power-save mode (see Figure 7). The undervolage deecion on he ransmier supply V CC is acive in normal-operaing mode and in receiveonly mode (see Figure 5). digial supply volage VIO = on VCC VCC undervolage monior VCC(UV,F) hyseresis VCC(UV,H) VCC undervolage monior VCC(UV,R) Delay(UV) delay ime undervolage any mode of operaion forced power-save mode normal-operaing mode RM X = don care low due he inernal pull-down resisor 1) 1) assuming no exernal signal applied Figure 7 Undervolage on he ransmier supply V CC 4.3.6 Volage Adapion o he Microconroller Supply The HS CAN ransceiver IFX1051 has wo differen power supplies, V CC and V IO. The power supply V CC supplies he ransmier and he normal-mode receiver. The power supply V IO supplies he digial inpu and oupu buffers and i is also he main power domain of he inernal logic. To adjus he digial inpu and oupu levels of he IFX1051 o he I/O levels of he exernal microconroller, connec he power supply V IO o he microconroller I/O supply volage (see Figure 13). Noe: In case he digial supply volage V IO is no required in he applicaion, connec he digial supply volage V IO o he ransmier supply V CC. Daa Shee 11 Rev. 1.0

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 IO or a pull-down resisor o GND. In case he V IO supply is acivaed and he logical pins are open, he IFX1051 eners ino he normal-operaing mode by defaul. The TxD inpu is pulled o logical high due o he inernal pull-up resisor o V IO. The HS CAN ransceiver IFX1051 will no influence he daa on he CAN bus as long he TxD inpu pin remains logical high. 5.3 TxD Time-ou Funcion The TxD ime-ou feaure proecs he CAN bus agains being permanenly blocked in case he logical signal a he TxD pin of a singular node on he bus is coninuously low. A coninuous low signal a he TxD pin migh have is roo cause in a locked-up microconroller or in a shor circui on he prined circui board, for example. In normal-operaing mode, a logical low signal applied o he TxD pin for he ime > TxD riggers he TxD ime-ou feaure and he IFX1051 disables he ransmier (see Figure 8). The receiver is sill acive and he daa on he bus can be sill moniored by he RxD oupu pin.

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 IFX1051 requires a signal change on he TxD inpu pin from logical low o logical high. The TxD Time-ou Funcion is a very effecive feaure o keep he sysem communicaion alive in case of a malfuncion of an individual node inside he nework.

Indusrial High Speed CAN-FD Transceiver 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 RM inpu pin o logical high changes he mode of operaion o he receive-only mode independen on he signals a he CANH, CANL and TxD pins. Noe: Noe: In case he TxD signal is low seing he RM inpu pin o logical low changes he operaing mode of 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 IFX1051 eners normal-operaing mode and he TxD inpu is se o logical low. Daa Shee 25 Rev. 1.0

Indusrial High Speed CAN-FD Transceiver Applicaion Informaion 8.3.1 Mode Change while he TxD Signal is low The example in Figure 14 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 IFX1051 is in receive-only mode he ransmier is urned off. The IFX1051 drives no signal o he HS CAN bus. The normal-mode receiver is acive in receive-only mode and he RxD indicaes he recessive signal on he HS CAN bus wih a logical high oupu signal. Changing he RM o logical low urns he mode of operaion o normal-operaing mode, while he TxD inpu remains logical low. The ransmier remains disabled unil he mode change is compleed. The normalmode receiver remains acive also during he mode change. In normal-operaing mode he ransmier becomes acive and he logical low signal on he TxD inpu drives a dominan signal o he HS CAN bus. The dominan bus signal is indicaed on he RxD oupu by a logical low signal. Changing he RM pin back o logical high, disables he ransmier. The normal-mode receiver and he RxD oupu remain acive and he recessive bus signal is indicaed on he RxD oupu by a logical high signal.

Indusrial High Speed CAN-FD Transceiver Applicaion Informaion 8.3.2 Mode Change while he Bus Signal is dominan The example in Figure 15 shows a mode change while he bus is dominan and he TxD inpu signal is se o logical high. While he ransceiver IFX1051 is in receive-only mode he ransmier is urned off. The IFX1051 drives no signal o he HS CAN bus. The normal-mode receiver is acive in receive-only mode and he RxD indicaes he dominan signal on he HS CAN bus wih a logical low oupu signal. Changing he RM o logical low urns he mode of operaion o normal-operaing mode, while he TxD inpu remains logical high. The ransmier remains disabled unil he mode change is compleed. The normalmode receiver remains acive also during he mode change. In normal-operaing mode he ransmier becomes acive, he bus remains dominan since he bus signal is driven from anoher HS CAN bus subscriber. The dominan bus signal is indicaed on he RxD oupu by a logical low signal. Regardless which mode of operaion is seleced by he RM inpu pin, he RxD oupu indicaes he signal on he HS CAN bus.
