Microchip ATA6613C-PLQW-1 System Basis Chip for Automotive CAN Networks

The increasing complexity of modern automotive electronic systems demands highly integrated and robust components. The Microchip ATA6613C-PLQW-1 stands out as a premier System Basis Chip (SBC) specifically engineered to serve as the foundational power and communication backbone for electronic control units (ECUs) within automotive Controller Area Network (CAN) applications.

This device exemplifies high integration by combining several critical functions into a single 32-pin VQFN package. At its core, it features a high-efficiency voltage regulator providing a stable 3.3 V or 5 V supply for a microcontroller and associated peripherals. Complementing this is a CAN transceiver that is fully compliant with the ISO 11898-2/-5 standards, ensuring robust and error-free communication on the CAN bus. Furthermore, the ATA6613C-PLQW-1 integrates four high-side drivers, which can be used to control lamps, LEDs, or other loads directly, thereby reducing the need for additional components.

A paramount requirement in the automotive industry is reliability and operational safety. This SBC is designed to operate within the harsh environment of an automobile, supporting a wide supply voltage range from 5.5 V to 28 V and enduring load-dump conditions up to 42 V. It includes comprehensive protective features such as over-temperature shutdown, over-current protection, and under-voltage reset generation for the microcontroller. Its automotive-grade qualification ensures it meets the stringent AEC-Q100 standards, making it a trustworthy solution for safety-critical applications.

The inclusion of a CAN FD-ready physical layer positions this SBC for next-generation vehicle networks. While supporting classic CAN, it is also capable of handling the higher data rates required by CAN Flexible Data Rate (FD) protocols, enabling faster data exchange for advanced driver-assistance systems (ADAS) and other data-intensive functions.

ICGOOODFIND: The Microchip ATA6613C-PLQW-1 is an optimal solution for designers seeking to simplify architecture, enhance reliability, and reduce the physical footprint of their automotive ECU designs. Its blend of power management, network communication, and output control, all while adhering to rigorous automotive standards, makes it an exceptional System Basis Chip for a wide array of in-vehicle applications.
