AMI Semiconductor has announced its next-generation controller area network (CAN) transceiver IC for high-speed, in-vehicle networking (IVN). The new AMIS-42665 high-speed single-chip transceiver combines operation to 1 Mbaud with an extremely low current standby mode and a bus-initiated wake-up capability.

Suitable for 12 V and 24 V automotive applications, the AMIS-42665 is fully compliant with the ISO 11898-2 and ISO 11898-5 standard and is ideal for vehicle body and comfort control functions ranging from electric windows to climate control. High tolerance to electromagnetic interference (EMI) and an electrostatic discharge (ESD) rating of ±8 kV HBM (human body model) eliminates the need for additional filtering and protection, while a low standby current helps designers to meet power targets when the vehicle is idle. Remote wake-up can be initiated locally or via the CAN bus, depending on specific application requirements.

The device integrates into a miniature ‘green’ SOIC 150-8 package all of the functionality needed to provide the interface between a CAN controller and the physical bus. Specifically, the device provides differential signaling capability to the CAN bus via the transmit and receive pins of the CAN controller. As package form factor and pin-count are fully compatible with other transceiver ICs (including the Philips TJA1040), the AMIS-42665 can be used as a ‘drop-in’ replacement to deliver optimum performance in existing designs as well to meet new application requirements.

Designed to provide high levels of in-built functionality, the AMIS-42665 offers a transmit data (TXD) dominant time-out function, thermal protection, short circuit protection, and protection against transients commonly found in the automotive environment. Carefully matched output signals eliminate the need for a common-mode choke by minimizing electromagnetic emission (EME), while the wide common-mode voltage range of the receiver inputs (±35 V) ensures low electromagnetic susceptibility (EMS).

AMIS42665 CAN transceivers are priced at $0.92 each in quantities in excess of 5K units.
