Overview
The NCV7356D1R2G, produced by onsemi, is a single wire CAN (Controller Area Network) transceiver designed to operate in various CSMA/CR (Carrier Sense Multiple Access with Collision Resolution) protocols, including the Bosch CAN version 2.0. This device is optimized for applications where high data rates are not required, allowing for cost reductions in both physical media components and microprocessor or dedicated logic devices. It supports both normal data rate mode and a high-speed data download mode for assembly line and service operations.
