1. Description
Atmel^® ATA6616/ATA6617 is a System-in-Package (SiP) product, which is particu-
larly suited for complete LIN-bus node applications. 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 (LIN-SBC) ATA6624, which has an integrated LIN
transceiver, a 5V regulator (85mA) 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 Atmel ATtiny87 with 8-Kbytes and the Atmel
ATtiny167 with 16-Kbytes flash memory.
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 applications as they
have when using discrete parts.
In section 2 you will find the pin configuration for the complete SiP. In section 3 the
LIN SBC is described, and in section 6 the AVR is described in detail.
