High-speed transceiver grants low power for in-vehicle networking apps

Pocatello, Idaho — AMI Semiconductor's single-chip transceiver combines 1-megabaud operation with extremely low-current standby mode and bus-initiated wake-up capability.

The company's next-generation controller area network (CAN) transceiver IC is intended for use in high-speed, in-vehicle networking (IVN) applications.

Suitable for both 12-V and 24-V automotive applications, the transceiver is fully compliant with both the ISO 11898-2 and ISO 11898-5 standard, and is suited 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 human body model (HBM) eliminates the need for additional filtering and protection, while
low standby current helps designers to meet power targets when the vehicle is idle. Remote wake-up can be initiated either locally or via the CAN bus.

The new 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. The package form factor and pin-count are fully compatible with other transceiver ICs (including the Philips TJA1040).

Designed to provide high levels of functionality, the transceiver offers a transmit data (TXD) dominant time-out function, thermal protection, short circuit protection, and protection against transients. 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).

The AMIS42665 CAN transceivers are priced at 92 cents each in 5,000-piece quantities. Click here for the AMIS42665 data sheet.
