description the TLE9222 realizes the physical interface between the flexray node and the communication channel. differential transmit and receive capability to the fl exray bus is provided, allowing the node bidirectional time multiplexed binary data stream transfer. the differential bus voltage is measur ed between two signal lines, denoted bp (bus plus) and bm (bus minus), defined as ubus = ubp - ubm . three different bus states are defined for the flexray bus; idle, data_0 and data_1 . for the idle state no differential voltage is driven to bp or to bm. the common mode bus biasing level will depend on the operation mode of all nodes on the bus. for the data_1 state a positive differential voltage is driven between bp and bm, whereas for the data_0 st ate a negative differential voltage is driven between bp and bm. 4.1 operation modes the TLE9222 supports two function al operation modes, bd_normal mode and bd_standby mode. in addition, the bd_off condition describes the behavior of the TLE9222 when unsupplied. mode transitions of the TLE9222 are triggered by host commands, underv oltage events and during power-up / -down, see figure 3 and table 1 . figure 3 operation

undervoltage detection after v cc and / or v io undervoltage detection, bd _standby mode is forced. 4 host command triggered by host command. 5 undervoltage recovery undervoltage recovery while host command requests bd_normal mode. 6 power-off supply voltage falls below the power-on threshold.

and th e sdo output is in high impedance state. if the v io reference supply is available, the logical inputs are set to their default states as given in table 2 . table 2 logic inputs when unconnected / default states input signal default state txd low txen high stbn low bge low data sheet 11 rev. 1.0 2015-06-12 TLE9222 functional description 4.2 communication controller interface the communication controller interf ace is the link between the tle 9222 and the flexray communication controller, comprising three digital signals: ? txen (transmit data enable not) input ? txd (transmit data) input ? rxd (receive data) output the logical i/o levels of all three digital pins are adapted to the v io digital reference voltage supply. figure 4 flexray physical layer bus signals the communication controller interface drives the serial digital data stream available on the txd input to the flexray bus via the transmitte r. simultaneously the receiver of the tl e9222 monitors the data on the flexray bus and transfers the data to a serial digital data stream back to the rxd output. a logical ?low?

signal on the rxd output. vice versa a logical ?hig h? on txd drives a data_1 signal on the flexray bus and results in a logical ?high? signal on the rxd output . the rxd output is also used to signal wake-up events while the transceiver is in bd_standby mode. the txen input is only functional in bd_normal mode and requires a transition from ?high? to ?low? for initiating bus transmissions. after tx en has been set ?low? while the bge in put is ?high?, a ?low? level on the txd input enables the transmitter. for avoiding unintentional blocking of the flexray bus in case of failures , the transmitter is protected with a time-out function. in case a time-out occurs, the transm itter will automati cally be disabled and the error will be signalled by the errn output and in the status register. a more detailed description of this fail safe function is given in chapter 4.7.3 . 4.3 bus guardian interface the bus guardian interface allows an external supervis ion device to immediate interrupt any bus transmission of the TLE9222. a logical ?low? signal on the bge input disables the transmitter of the TLE9222 while operating in bd_normal mode, regardless of the signals on the txd and txen inputs. for increasing the ecu system safety level, an enhanced redundant feedback path has been implemented for the bus guardian interface. a monitoring circuit direct ly at the transmitter output stages provides reliable feedback by setting the errn output ?low? and indication with the bge flag in the status register after the transmitter has been disabled th rough the bus guardian interface. the logical i/o level of the bge input is ad apted to the digital reference voltage level uv io . together with the txen input, the bge input is monitored fo r the transmitter time-out function (see chapter 4.7.3 ). additionally, the status register includes the rxen (recei ve enable not) flag that indicates activity (data_0 or data_1) on the flexray bus. this dete ction is only active in bd_normal mode. the rxen bit can be read out with the spi interfac e as described in chapter 4.8 . 4.4 host interface the host interface enables the host to control th e operation mode of the TLE9222 and to flag status information. the host inte rface is implemented using hard wired signals, option a according to the flexray epl spec. 3.0.1. the stbn (standby not) in put controls the operation mode of the TLE9222. unless the TLE9222 is being forced to bd_standby mode because of unde rvoltage events, the host command wi ll set operation mode as given in table 3 . mode change by host command is completed within the time dbd modechange after the host command is applied. voltage spikes on th e stbn input that are shorter than dbdlogic filter are filtered out and ignored. table 3 host command stbn resulting operation mode high bd_normal low bd_standby data sheet 13 rev. 1.0 2015-06-12 TLE9222 functional description figure 5 mode control with the stbn input the errn output is used to signal events detected by the TLE9222 to the host controller. depending on the provided host command, the errn output indicates errors or wake-up events, see table 4 . the TLE9222 reacts on and signals these events on the errn output within the time dreactiontime errn . detailed information about the detect ed events as given in table 4 can be read out from the status register with the spi interface as described in chapter 4.8 . table 4 signalling on the errn and rxd pins stbn errn rxd cause / comment effect bd_normal mode high high high / low 1) 1) depending on bus state; rxd ?low?

and bge ?high?), the digital input data on txd is compared with the received data on th e rxd output. if the data is not identi cal, a failure condition is identified. both the positive and the negative edges on the txd inpu t signal triggers an internal comparator to compare the txd signal with the rxd signal. the results are stored in an internal error counte r. when the internal error counter exceeds 10 reported comparison failures, the bus error flag will be set. the error counter is reset when the transmitter is deactivated. 4.7.2.2 bus overcurrent the bp and bm bus pins have implemented current sens ors for detection of overcu rrent conditions in the direction in or out of the pins. detect ion of overcurrent is the typical signat ure of a short circuit of one of the bus lines to the ground or a supply line. 4.7.3 transmitter time-out for avoiding unintentional blocking of the flexray bus in case of e.g. a malfunctioning microcontroller or short circuits on the pcb, the transmitter is protec ted with a time-out functi on. when the transmitter is activated for bus transmission while in bd_normal mode, with a ?low? signal on txen and ?high? on bge, a timer is started. in case a time-out occurs, the transm itter will automatically be disabled and the failure will be signaled on the errn output and in the status register. the transmitter timer is reset wh en the transmitter is deactiva ted with either txen or bge. 4.7.4 v io undervoltage-flag during v io undervoltage events, the spi register is bloc ked and can not be read out. after undervoltage recovery, depending on host command and the status of other register flags, the v io -undervoltage flag may or may not be set. please refer to chapter 4.7.6 . 4.7.5 spi-error flag the spi-error flag is used for indicati on of incorrect spi read-out procedur e, please find detailed description in chapter 4.8.1 . 4.7.6 error flag if any local errors or bus errors are detected, the resp ective bit in the status register is flagged together with the error flag (bit 12). if the error flag is set, but no other error contributing flags in the status register set, then this indicates that a v io undervoltage event has occu rred in the past but recove ry has already taken place. while the error flag is set and the host command on the stbn input is ?high?, the errn output is ?low?. 4.7.7 mode flags the mode flag in the status register indicates the cu rrent operating mode of th e TLE9222, regardless of the applied host command. if the TLE9222 is in bd_standby mode, bit 1 will be ?low?. if the current operation mode is bd_normal, bit 1 will be ?high?. the mode fl ag will only toggle during an operation mode change, i.e. not be reset by spi register read-out. the mode indicati on can be beneficial for the host when the TLE9222 is forced to a different mode than requ ested with the host command during v cc undervoltage events. data sheet 21 rev. 1.0 2015-06-12 TLE9222 functional description 4.8 spi interface and status register the TLE9222 has a 16-bit spi interface for reading out the internal status register. the bits in the register reflects detailed flags regarding ex ternal events such as wake-up and power-on recognition, detection of errors / warnings and oper ation mode indication, see table 5 . table 5 bit definition of the status register bit name indication comment bit 0 remote wake-up flag ?low?: remote wake-up detected ?

signal on scsn, which wi ll cause the sdo output to be set ?low? (see figure 13 ). after the time dspi lead the status register data can be shifted out on the sdo output synchronized with the rising edge of a clock signal on the sclk input. with a clock signal period of dspi clk , the TLE9222 supports spi data rates in the range 10 kbit/s to 4 mbit/sif a transition on scsn from ?high? to ?low? is detected while sclk is ?high?, this would be identified as a spi error. within the scsn period, the time dspi scsn_low while the signal on scsn is ?l ow?, exactly 16 clock cycles are expected for a correct read-out proc edure. incorrect spi access, with more or less than 16 sclk cycles or wrong timing, is protected by the spi timer. if the read-out time dspi scsn_low expires, the sdo output is set to ?high impedance? within the time dspi sdoz . additionally the error flag and sp i-error flag in the status register will be set, while the state of all other latched bits are left unchanged. figure 14 spi read-out after a correct spi read-out process, the information on the errn output and the flags in the status register are refreshed. next spi read-o ut can be initiated after scsn is set ?high? for the time dspi interframe . the spi interface is available in both bd_normal mo de and bd_standby mode, but spi readout should not occur at the same time as a mode chan ge with the host in terface, the time dbd modechange must be respected. the spi register is also blocked during undervoltage conditions on v io . while the TLE9222 is set in bd_standby with host command (pin stbn = ?l ow?) and no wake-up or errors have been detected, the spi interface requires an enable time of dspi leadstbok from scsn goes ?low? until the first rising edge on the clock signal on the sclk input can be applied.

when the transmitter is reliably disabled. by taking advantage of this safety feature, the ecu diagnostic coverage can be increased. figure 22 application diagram in figure 22 an application example of an automotive ecu for safety critical applicat ions is shown. together with a safety mcu supply ic, e.g. th e infineon tlf35584, that incorporates safe state control functionality, the bge input of the TLE9222 is connected to the safe stat e output. if the safety su pply ic detects unexpected behavior at the supply voltages or incorrect mcu behavior through th e functional watchdog, the TLE9222 TLE9222_application_safety_v01 ecu v bat TLE9222px flexray transceiver gnd v cc bp errn rxd txen txd sclk bm v io sdo stbn bge scsn bm bp tlf35584 multi voltage safety micro processor supply application microcontroller e.g. tc2xx aurix mcu 1 3 2 quc qco scsn sdo sclk sdi ss1 v dd vs1 sw1 fb data sheet 40 rev. 1.0 2015-06-12 TLE9222 application information makes sure there is no influence to the flexray bus after the bge inpu t is set ?low?. additionally, the microcontroller can detect the true state of the transc eiver output drivers from the errn out, which should trigger a spi readout of the status re gister. by observing the bge flag being set ?low?, the mcu has verified that the TLE9222 has been safely disconnected from the bus by th e safety supply ic. it is recommended to follow these steps for the ecu software implementation. af ter ecu power-up, the mcu should test and verify the correct beha vior of the fail safe state as a part of its initialization routine, before releasing the transceiver for bus access and transmission. 7.5 minimizing ecu current consump tion through bd_standby mode the very low current consumption of iv cc_stb_85 and iv cc_stb_150 of the TLE9222 can only be reached with the correct system implementation and software control. while operating in ecu low power mode with the TLE9222 in bd_standby mode, the logic inputs should be in their default states (see table 2 ). this prevents current to flow through the implemen ted pull-up / pull-down circuits. secondly, the logic outputs, rxd and errn, should be in their default cond ition ?high? for bd_standby mode (see table 4 ). after the TLE9222 is set to bd_standby mode, it is recommended to perform a sp i readout for verifying correct state transition and to clear pending diagnosis flags. a mcu in low-power mode should continuously (by inte rrupt) or periodically (by polling) monitor the errn output for wake-up information. even if the wake-up function is not being used, the mcu should clear the flags of the status register by spi readout. for simpler ec u implementations, not usin g the spi interface, a mode change cycle to bd_normal mode and back to bd_standby mode again has the same effect. 7.6 further application information ?
