ATA6563

The ATA6563 is a high-performance CAN transceiver designed by Microchip Technology for robust and reliable communication in automotive and industrial applications. It supports data rates up to 1 Mbps, making it suitable for both standard and high-speed CAN protocols as defined by ISO 11898-2 and ISO 11898-3 standards. The device features a wide supply voltage range from 3.0 V to 5.5 V, enabling compatibility with various power systems commonly found in modern vehicles and embedded systems. One of the key characteristics of the ATA6563 is its excellent electromagnetic compatibility (EMC) performance, which ensures stable operation even in electrically noisy environments typical of automotive settings. It includes integrated protection features such as short-circuit protection, overvoltage protection, and thermal shutdown, enhancing system reliability and safety. Additionally, the transceiver supports hot-plug capability, allowing safe insertion or removal of nodes without disrupting the network. The ATA6563 operates in two modes: normal mode and low-power sleep mode. In sleep mode, the quiescent current drops significantly—down to 1 µA—which makes it ideal for energy-efficient designs where power conservation is critical. Its differential signaling capability provides immunity to common-mode noise, ensuring accurate signal transmission across long cables and harsh conditions. This transceiver is widely used in automotive electronic control units (ECUs), including engine management, body control modules, and infotainment systems. It also finds application in industrial automation, medical devices, and building automation systems where reliable serial communication is essential. The chip’s compact 8-pin SOIC package and low component count simplify PCB design and reduce overall system cost. With its advanced fault detection mechanisms, including open-wire detection and bus line monitoring, the ATA6563 enables efficient diagnostics and enhances system uptime. It is fully compatible with standard CAN controllers and requires minimal external components, streamlining integration into existing designs. The device is qualified to AEC-Q100 Grade 1, ensuring it meets stringent automotive reliability standards for temperature cycling, humidity, and mechanical stress.
