Description
Atmel ATA6616C/ATA6617C is a System-in-Package (SiP) product, which is particularly
suited for complete LIN-bus node applications. It consists of two ICs in one package sup-
porting 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 reg-
ulator (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 1. “Atmel ATA6616C/ATA6617C LIN System in Package Solution (SIP)” on page
3
you will find the pin configuration for the complete SiP. In
Section 3. “LIN System-basis-
chip Block” on page 7
the LIN SBC is described, and in
Section 4. “Atmel
ATtiny87/ATtiny167 Microcontroller Block for Atmel ATA6616C/ATA6617C” on page 26
the
AVR is described in detail.
