optimized for in-car low-speed communication

baud rate up to 125 kbd

up to 32 nodes can be connected

supports unshielded bus wires

very low electromagnetic emission (eme) due to built-in slope control function and a
very good matching of the canl and canh bus outputs

very high electromagnetic immunity (emi) in normal and low power operating modes

fully integrated receiver filters

transmit data (txd) dominant time-out function

bus failure management

supports single-wire transmission modes with ground offset voltages up to 1.5 v

automatic switching to single-wire mode in the event of bus failures, even when the canh bus wire is short-circuited to vcc

automatic reset to differential mode if bus failure is removed

full wake-up capability during failure modes

protections

bus pins short-circuit safe to battery and to ground

thermally protected

bus lines protected against transients in an automotive environment

an unpowered node does not disturb the bus lines

support for low power modes

low current sleep mode and standby mode with wake-up via the bus lines

power-on reset flag on the output
