4.9
The TLE 7263E is optimized for high speed data transmission up to 1 MBaud in
automotive applications and is compatible to the ISO 11898 standard. It works as an
interface between the CAN protocol controller and the physical bus lines.
This HS-CAN module also supports extended bus error detection via a general error flag
as well as individual notification flags, e.g. temperature shutdown and TxD time-out flag,
within the SPI.
To reduce EMI the dynamic slopes of the CANL and CANH signals both are limited and
symmetric. This allows the use of an unshielded twisted or parallel pair of wires for the
bus.
Furthermore there is implemented a time-out feature to prevent the bus from being
blocked by a permanently dominant TxD input signal. Both, the CANL and CANH output
stage are automatically disabled after the delay time
In order to protect the transceiver output stages from being damaged by shorts on the
bus lines, current limiting circuits are integrated. The CANL and CANH output stage
respectively are protected by an additional temperature sensor, that disables them as
soon as the junction temperature exceeds the maximum value. During the temperature
shut-down condition of the CAN output stages receiving messages from the bus lines is
still possible.
Wake-Up Indication: A bus wake-up via a CAN message (minimum dominant time

V
be enabled to reset the wake-up capability after a bus wake event and after power-up.
Bus Failure Flag: signalizes a bus line short circuit condition to GND, V
SPI bit 11 in the SPI Output Data “CAN Bus Failure”.
Remarks: Flag is set after four consecutive recessive to dominant cycles on pin TxD
when trying to drive the bus dominant. The bus failure flag is cleared upon 4 recessive
to dominant edges at TxD without failure condition.
Local Failure Flag: signalizes the local failure conditions listed in the text below via SPI
bit 10 in the SPI Output Data “CAN Local Failure”.
Remark: Flag is cleared upon dominant level at RxD while TxD is recessive.
General: release of the transmitter stage only after transition into CAN RxD Only mode
and transition back into SBC Active Mode.
