Product Summary

The ATA66140 is a System-in-Package (SiP) product, which is particularly suited for complete LIN-bus slave-node applications. The ATA66140 supports highly integrated solutions for in-vehicle LIN networks. The ATA66140 is the LIN-system-basis-chip (LIN-SBC) , which has an integrated LIN transceiver, a 5V regulator and a window watchdog. The second chip is an automotive microcontroller from Atmels series of AVR 8-bit microcontroller with advanced RISC architecture.
