AMI Semiconductor has introduced a controller area network (CAN) transceiver IC for high-speed, in-vehicle networking. This new AMIS-42665 high-speed, single-chip transceiver operates at data rates of 1 MB and features an extremely low-current standby mode and a bus-initiated, wake-up capability.

Suitable for both 12 V and 24 V automotive applications, the AMIS-42665 is fully compliant with both the ISO 11898-2 and ISO 11898-5 standards. Because of its relative immunity to electromagnetic interference and an electrostatic discharge rating of 8 kV, the need for additional filtering and protection is eliminated. The low standby current helps designers meet power targets when the vehicle is idle. Remote wake-up can be initiated either locally or via the CAN bus, depending on specific application requirements. The new device integrates the functionality necessary to provide the interface between a CAN controller and the physical bus. Specifically, the device provides a differential signaling capability to the CAN bus via the transmit and receive pins of the CAN controller.

The fact that the transceiver can be used to wake up the rest of the CAN module on receipt of a local or bus-driven wake-up command will help designers minimize component count and board space while meeting critical power consumption objectives. AMIS42665 CAN transceivers are priced at $0.92 each, in quantities in excess of 5000 units.
