Product Introduction

Overview

The ISO1042DW Isolated CAN Transceiver, produced by Texas Instruments, is a galvanically-isolated controller area network (CAN) transceiver that meets the specifications of the ISO11898-2 (2016) standard. This device is designed to provide high reliability and robustness in various industrial and automotive applications. The ISO1042DW supports both classic CAN up to 1 Mbps and CAN FD (Flexible Data Rate) up to 5 Mbps, enabling faster data transfer compared to traditional CAN systems.

The ISO1042DWEVM is an evaluation module (EVM) specifically designed for evaluating the performance of the ISO1042DW transceiver. This EVM includes test points for all main points necessary for evaluation, such as GND, VCC, TXD, RXD, CANH, and CANL, and supports various CAN bus configurations and protection schemes.
