1. Description
ATA6602/ATA6603 is a single-package dual-chip circuit family for LIN-bus slave node applications. It supports highly integrated solutions for in-vehicle LIN networks. The LIN-system-basis-chip (LIN-SBC) consists of a LIN transceiver, voltage
regulator and window watchdog. The second chip is a microcontroller out of Atmel®'s series of AVR 8-bit microcontrollers with advanced RISC architecture.
