Description
ATA6612/ATA6613 is a System-in-Package (SiP) product, which is particularly suited for complete LIN-bus slave-node applications. It supports highly integrated solutions for in-vehicle LIN networks. The first chip is the LIN-system-basis-chip (LIN-SBC) ATA6624, which has an integrated LIN transceiver, a 5V regulator and a window watchdog. The second chip is an automotive microcontroller from Atmel’s series of Atmel AVR 8-bit microcontroller with advanced RISC architecture.
The ATA6612 consists of the LIN-SBC ATA6624 and the ATmega88 with 8 Kbytes flash. The ATA6613 consists of the LIN-SBC ATA6624 and the ATmega168 with 16 Kbytes flash. All pins of the LIN System Basis Chip as well as all pins of the Atmel AVR microcontroller are bonded out to provide customers the same flexibility for their applications as they have when using discrete parts.
In section 2 you will find the pin configuration for the complete SiP. In sections 3 to 5 the LIN SBC is described, and in sections 6 to 7 the Atmel AVR is described in detail.
