High-Performance System Basis Chip: Microchip ATA6622C-PGQW-1 for Automotive Networking Applications

The increasing complexity of modern automotive electronic architectures demands highly integrated, reliable, and robust components. At the heart of many advanced in-vehicle networks lies the System Basis Chip (SBC), a pivotal device that combines several critical functions into a single package. The Microchip ATA6622C-PGQW-1 stands out as a premier example of such a component, engineered specifically to meet the stringent requirements of the automotive industry.

This SBC is designed to serve as a local power supply and communication gateway for electronic control units (ECUs), particularly in Controller Area Network (CAN) and CAN FD (Flexible Data-Rate) applications. Its high level of integration is a key advantage, consolidating a CAN FD transceiver, a LIN transceiver, and a voltage regulator into one compact 32-pin VQFN package. This integration significantly reduces the overall system footprint, component count, and bill-of-materials costs, while simultaneously enhancing reliability by minimizing board interconnections.

A primary strength of the ATA6622C-PGQW-1 is its unwavering focus on robustness and electromagnetic compatibility (EMC). It is designed to operate flawlessly in the electrically harsh environment of an automobile, where voltage transients, noise, and extreme temperatures are commonplace. The device offers excellent ESD protection and meets the rigorous ISO 11898-2:2016 standard for high-speed CAN transceivers. Furthermore, its integrated low-dropout (LDO) voltage regulator provides a stable 5V or 3.3V supply for an associated microcontroller, featuring over-temperature and short-circuit protection to ensure system safety.

The inclusion of a LIN transceiver compliant with LIN 2.x and SAE J2602 standards adds another layer of functionality, enabling the creation of mixed-protocol sub-networks. This makes the chip exceptionally versatile for a wide range of automotive body and comfort applications, such as door control modules, seat controllers, and sensor interfaces. Its support for CAN FD allows for higher data-rate communication, which is essential for supporting the increasing data traffic in vehicles without compromising the real-time performance of the CAN network.

ICGOOODFIND: The Microchip ATA6622C-PGQW-1 is a highly integrated and robust System Basis Chip that exemplifies the trend towards functional consolidation in automotive electronics. By combining power management and dual network interfaces with superior protection features, it provides a compact, cost-effective, and reliable foundation for next-generation automotive networking ECUs, simplifying design and accelerating time-to-market for manufacturers.
