1. 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
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 AVR
microcontroller are bonded out to provide customers the same flexibility for their appli-
cations 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 AVR is described in detail.
