AMIS-42700 Dual High-Speed CAN Transceiver

Preliminary Data Sheet

1. 0 Key Features

Controller area network (CAN) is a serial communication protocol, which supports distributed real-time control and multiplexing with

high safety level. Typical applications of CAN-based networks can be found in automotive and industrial environments.

The AMIS-42700 Dual-CAN transceiver is the interface between up to two physical bus lines and the protocol controller and will be

used for serial data interchange between different electronic units at more than one bus line. It can be used for both 12V and 24V

systems.

The circuit consists of following blocks:

• Two differential line transmitters

• Two differential line receivers

• Interface to the CAN protocol handler

• Interface to expand the number of CAN busses

• Logic block including repeater function and the feedback suppression

• Thermal shutdown circuit (TSD)

• Short to battery treatment circuit

Due to the wide common-mode voltage range of the receiver inputs, the AMIS-42700 is able to reach outstanding levels of

electromagnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent

matching of the output signals.

2. 0 Key Features

• Fully compatible with the ISO 11898-2 standard

• Certified “Authentication on CAN Transceiver Conformance (d1.1)”

• High speed (up to 1 Mbit/s)

• Ideally suited for 12V and 24V industrial and automotive applications

• Low EME common-mode-choke is no longer required

• Differential receiver with wide common-mode range (+/- 35V) for high EMS

• No disturbance of the bus lines with an un-powered node

• Transmit data (TxD) dominant time-out function

• Thermal protection

• Bus pins protected against transients in an automotive environment

• Power down mode in which the transmitter is disabled

• Short circuit proof to supply voltage and ground

• Logic level inputs compatible with 3.3V devices

• ESD protection guaranteed up to ±8KV
