data sheet 6 rev. 1.1, 2014-10-09 tle8250g functional description 4 functional description can is a serial bus system that connects microcontrollers , sensor and actuators for real-time control applications. the usage of the c ontrol a rea n etwork (abbreviated can) within road vehi cles is described by the international standard iso 11898. according to the 7 layer osi refe rence model the physical layer of a can bus system specifies the data transmission from one can node to a ll other available can nodes inside the network. the physical layer specification of a can bus system includes all electrical and mechanical specifications of a can network. the can transceiver is part of the physical layer specification. seve ral different physical layer definitions of a can network have been developed over the last years. the tle8250g is a high speed can transceiver without any dedicated wake-up function. high speed ca n transceivers without wake-up function are defined by the international standard iso 11898-2. 4.1 high speed c an physical layer figure 3 high speed can bus signals and logic signals v cc can_h can_l txd v cc = can power supply txd = input from the microcontroller rxd = output to the microcontroller canh = voltage on the canh input/output canl = voltage on the canl input/output v diff = differential voltage between canh and canl v diff = v canh C v canl rxd v diff dominant recessive v cc v cc t t t t v diff = iso level dominant v diff = iso level recessive
tle8250g functional description data sheet 7 rev. 1.1, 2014-10-09 the tle8250g is a high speed can transceiver, operating as an interface between the can controller and the physical bus medium. a hs can network is a two wire, di fferential network which allows data transmission rates up to 1 mbit/s. characteristic fo r a hs can network are the two signal states on the can bus: ?dominant? and ?recessive? (see figure 3 ). the pins canh and canl are the interf ace to the can bus and both pins o perate as an input and as an output. the pins rxd and txd are the interface to the microcontro ller. the pin txd is the serial data input from the can controller, the pin rxd is th e serial data output to the can controller. as shown in figure 1 , the hs can transceiver tle8250g has a receive and a transmit unit, allowing the transceiver to send data to the bus medium and monitor the data from the bus medium at the same time. the hs can transceiver tle8250g converts the serial data stream available on the tran smit data input txd, into a differenti al output signal on can bus, provided by the pins canh and canl. the receiv er stage of the tle8250g monitors the data on the can bus and converts them to a serial, single ended signal on the rxd output pin. a logical ?low? signal on the txd pin creates a ?dominant? signal on the can bus, followed by a logical ?low? signal on the rxd pin (see figure 3 ). the feature, broadcasting data to the can bus and listening to the da ta traffic on the can bus simultaneous is essential to support the bit to bit arbitration inside can networks. the voltage levels for hs can transceivers are defined by the iso 11898-2 and the iso 11898-5 standards. if a data bit is ?dominant? or ?recessive? depends on the voltage difference between pins canh and canl: v diff = v canh - v canl . in comparison to other differential ne twork protocols the differential signal on a can network can only be larger or equal to 0 v. to transmit a ?dominant? sig nal to the can bus the differential signal v diff is larger or equal to 1.5 v. to receive a ?recessive? signal from the can bus the differential v diff is smaller or equal to 0.5 v. partially supplied can networks are networks where the can bus participants have different power supply conditions. some nodes are connected to the power supp ly, some other nodes are disconnected from the power supply. regardless, if the can bus par ticipant is supplied or not supplied, each participant connected to the common bus media must not disturb the communication. the tle8250g is designed to support partially supplied networks. in power down mode, the receiver input resi stors are switched off and the transceiver input is high resistive.
data sheet 8 rev. 1.1, 2014-10-09 tle8250g functional description 4.2 operation modes three different operation modes are available on tle8250g . each mode with specific characteristics in terms of quiescent current or data transmission. for the mode selection the digital input pins nen and nrm are used. figure 4 illustrates the differ ent mode changes depending on the status of the nen and nrm pins. after suppling v cc to the hs can transceiver, the tle8250g starts in st and-by mode. the internal pull-up resistors are setting the tle8250g to stand-by per defaul t. if the microcontroller is up and running the tle8250g can change to any operation mode within the time for mode change t mode . figure 4 operation modes the tle8250g has 3 major operation modes: ? stand-by mode ? normal operation mode ? receive-only mode table 2 operating modes mode nrm nen bus bias comments normal operation ?high? ?low? v cc /2 output driver stage is active. receiver unit is active. stand-by ?low? or ?high? ?high? floating output driver stage is disabled. receiver unit is disabled. receive-only ?low? ?low? v cc /2 output driver stage is disabled. receiver unit is active. v cc off ?low? or ?high? ?low? or ?high? floating output driver stage is disabled. receiver unit is disabled. nrm = 0 nen = 0 nrm = 1 nen = 0 undervoltage detection on v cc power down v cc < v cc(uv) start C up supply v cc nen = 1 stand-by mode nrm = 0/1 nen = 0 normal operation mode nrm = 1 nen = 0 receive-only mode nrm = 0 nrm = 0 nen = 0 nrm = 0/1 nen = 1 nrm = 0/1 nen = 1 nrm = 1 nen = 0
tle8250g functional description data sheet 9 rev. 1.1, 2014-10-09 4.3 normal operation mode in normal operation mode the hs can transceiver tle8250g sends the serial data stream on the txd pin to the can bus while at the same time the data available on the can bus are monitored to the rxd pin. in normal operation mode all functions of the tle8250g are active: ? the output driver stage is active and drives data from the txd to the can bus. ? the receiver unit is active and provides the data from the can bus to the rxd pin. ? the bus basing is set to v cc /2. ? the under-voltage monitoring on the power supply v cc is active. to enter the normal operation mode set the pin nrm to logical ?high? and the pin nen to logical ?low? (see table 2 or figure 4 ). both pins, the nen pin and the nrm pin have internal pull-up resistors to the power-supply v cc . 4.4 receive-only mode the receive-only mode can be used to test the connection of the bus medium. the tle8250g can still receive data from the bus, but the output driv er stage is disabled and therefore no da ta can be sent to the can bus. all other functions are active: ? the output driver stage is disabled and data which ar e available on the txd pin are blocked and not send to the can bus. ? the receiver unit is active and provides the data from the can bus to the rxd output pin. ? the bus basing is set to v cc /2. ? the under-voltage monitoring on the power supply v cc is active. to enter the receive-only mode set the pin nrm to logical ?low? and the pin nen to logical ?low? (see table 2 or figure 4 ). in case the receive-only mode will not be used, the nrm pin can be left open. 4.5 stand-by mode stand-by mode is an idle mode of the tle8250g with optimized power consumption. in stand-by mode the tle8250g can not send or receive any data. the output driv er stage and the receiver unit are disabled. both can bus pins, canh and canl are floating. ? the output driver stage is disabled. ? the receiver unit is disabled. ? the bus basing is floating. ? the under-voltage monitoring on the power supply v cc is active. to enter the stand-by mode set the pin nen to logical ? high?, the logical state of the nrm pin has no influence for the mode selection (see table 2 or figure 4 ). both pins the nen and the nrm pin have an internal pull-up resistor to the power-supply v cc . if the stand-by mode is not used in the application, the nen pin needs to get connected to gnd. in case the nrm pin is set to logical ?low? in stand-by mode, the internal pull-up resistor causes an additional quiescent current from v cc to gnd, therefore it is recommended to se t the nrm pin to logical ?high? in stand-by mode or leave the pin open if the receive-only mode is not used in the application. 4.6 power down mode power down mode means the tle8250g is not supplied. in power down the differential input resistors of the receiver stage are switched off. the canh and canl bu s interface of the tle8250g acts as an high impedance input with a very small leakage current. the high ohmic input doesn?t influence the ?recessive? level of the can network and allows an optimized eme performance of the whole can network.
data sheet 10 rev. 1.1, 2014-10-09 tle8250g fail safe functions 5 fail safe functions 5.1 short circuit protection the canh and canl bus outputs are short-circuit-proof, either against gnd or a positive supply voltage. a current limiting circuit protects the tran sceiver against damages. if the device is heating up due to a continuos short on canh or canl, the internal over-temperature protection switches off the bus transmitter. 5.2 open logic pins all logic input pins have internal pull-up resistor to v cc . in case the v cc supply is activated and the logical pins are open or floating, the tle8250g enters into the stand-by mode per default. in stand-by mode the output driver stage of the tle8250g is disabled, the bus biasing is shut off and the hs can transceiver tle8250g will not influence the data on the can bus. 5.3 txd time-out function the txd time-out feature protects the can bus against permanent blocking in case the logical signal on the txd pin is continuously ?low?. a conti nuous ?low? signal on the txd pin can have it?s root cause in a locked-up microcontroller or in a short on the printed circuit board for example. in normal operation mode, a logical ?low? signal on the txd pin for the time t > t txd the tle8250g activates the txd ti me-out and the tle8250g disables the output driver stage (see figure 5 ). the receive unit is still active and the data on the bus ar e monitored at the rxd output pin. figure 5 txd time-out function figure 5 shows how the output driver stage is deactivated an d activated again. a permanent ?low? signal on the txd input pin activates the txd time-out function and deactivates the output driver stage. to release the output driver stage after a txd time-out event the tle8250g requires a signal change on the txd input pin from logical ?low? to logical ?high?. 5.4 under-voltage detection the hs can transceiver tle8250g is equipped with an under-voltage detection on the power supply v cc . in case of an under-voltage event on v cc , the under-voltage detection changes the operation mode of tle8250g to the stand-by mode, regardless of the logi cal signal on the pins nen and nrm (see figure 6 ). if the transceiver tle8250g recovers from the under-voltage event, the operation mode returns to the programmed mode by the logical pins nen and nrm. txd t t canh canl rxd t txd time - out txd time C out released t > t txd
