ATA664251 is a system-in-package (SiP) product, which is especially well suited for complete LIN-bus node applications. It is designed specifically for LIN switch applications and includes nearly the entire LIN node. The ATA664251 consists of two ICs in one package supporting highly integrated solutions for in-vehicle LIN networks. The first chip is the ATA664151 LIN system basis chip (LIN-SBC), which has an integrated LIN transceiver, a 5V regulator (80mA), a window watchdog, an 8-channel high-voltage switch interface with high-voltage current sources and a 16-bit SPI for configuration and diagnosis. The second chip is an automotive microcontroller from the AVR 8-bit microcontroller series from with advanced RISC architecture and the ATtiny167 with 16-Kbyte flash memory. All pins of the LIN-SBC as well as all pins of the AVR microcontroller are bonded out to provide customers the same flexibility for their applications they are accustomed to when using discrete parts.
