We'll tell you all you need to know to start evaluating and working with this product.
Atmel® ATA664251 is a System-in-Package (SiP) product, which is particularly suited for complete LIN-bus node applications. It is especially designed for LIN-switch applications and includes nearly the complete LIN node. It consists of two ICs in one package supporting highly integrated solutions for in-vehicle LIN networks. The first chip is the LIN-system-basis-chip (LINSBC) ATA664151, 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 series of AVR® 8-bit microcontrollers from Atmel with advanced RISC architecture, the Atmel ATtiny167 with 16-Kbytes 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 as they have when using discrete parts.
