AMI Semiconductor Offers GIFT-Compliant, Single-Chip, Low-Speed Fault-Tolerant CAN Transceiver for Automotive Applications

Certified interoperability and pin compatibility with third party CAN modules allows ‘drop-in’ replacement in existing CAN applications

Pocatello, Idaho - June 20, 2005 - AMI Semiconductor, a designer and manufacturer of state-of-the-art integrated mixed-signal and structured digital products, is now offering a compact, low speed, controller area network (CAN) transceiver IC that has been fully verified and certified to the requirements of the generalized interoperable fault tolerant CAN transceiver (GIFT) specification. GIFT compliance means that the AMIS-41682 CAN transceiver meets the specifications and standards needed to ensure true interoperability with similar devices from other automotive semiconductor manufacturers.

Fully compliant with the ISO 11898-3 CAN standard, the AMIS-41682 provides the interface between the protocol controller and the physical wires of the bus lines in a CAN network. GIFT-compliance, and pin- and function-compatibility with existing standard parts makes it ideal for both new applications and for use as a drop-in replacement in existing designs using transceiver modules from other suppliers.

“GIFT is a joint project between the automotive and semiconductor industries that aims to create a specification for a CAN transceiver module in such a way that technical interoperation of devices from different manufacturers is possible,” states Bob Klosterboer, senior vice president of integrated mixed-signal products at AMIS. “The AMIS GIFT-compliant low-speed CAN transceiver gives automotive manufacturers and OEMs the peace of mind that they can choose a compact, cost effective, single-chip solution that can be seamlessly integrated into their new and existing CAN designs.”

Designed for existing and emerging automotive applications, the AMIS-41682, low-speed, fault-tolerant CAN transceiver combines very low power operation with high tolerance to electrostatic discharge (ESD) and electromagnetic interference (EMI). The device operates with a typical supply current of just 3.7mA. Three low-power modes – sleep, standby and power-on standby –further reduce power consumption when the transceiver is inactive. In sleep mode the total power consumption is typically 35µA. Wake-up can be controlled via bus lines, power-on reset flag outputs and edge-sensitive wake-up input.

The device combines a built-in slope control function with excellent differential output matching drivers to realize very low electromagnetic emissions. A fully integrated differential receiver filter with a wide common-mode range ensures high tolerance to EMI. Use of AMI Semiconductor’s advanced high-power, mixed-signal semiconductor processes results in ESD ratings of ±8 kV human body model (HBM) on all high-voltage pins, as well as providing protection against short circuit and reverse battery conditions.

The GIFT-compliant AMIS-41682 is available in a ‘green’ SOIC 150 14-pin package and is priced, for budgetary purposes, at $1.06 per unit/€0.90 per unit in quantities of 5,000 units. Please contact AMIS for a custom quote based on volume, use and application.
