Microchip's ATA6560 and ATA6561 are high-speed CAN transceivers that provide an interface between a CAN protocol controller and the physical 2-wire CAN bus. They are available as automotive and industrial grade parts. These transceivers were originally created for automotive applications and are designed for high-speed and reliable communication protocol for applications requiring robust communications at bit rates reaching 5 Mbps.

A CAN bus is a low-cost, reliable way to function in a difficult electrical environment with a high degree of real-time capability in a user's industrial designs. It offers improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance as well as features including ideal passive behavior to the CAN bus when the supply voltage is off and direct interfacing to microcontrollers with supply voltages from 3 V to 5 V (ATA6561). The three operating modes combined with the dedicated fail-safe features make the ATA6560 and ATA6561 excellent choices for all types of high-speed CAN networks, especially in nodes requiring a low-power mode with wake-up capability via the CAN bus. They are ideal for any application that requires a robust reliable.
