The ATA6617 is a system-in-package (SIP) solution that integrates the ATA6624 LIN system basis chip (SBC) with an AVR microcontroller (ATtiny167) in a single QFN 5mm Ã— 7mm package, where the ATA6624 LIN SBC includes LIN Transceivers, voltage regulators, and watchdogs. With this system-in-package solution, customers can create complete LIN nodes with just one IC. Based on Atmel's second-generation LIN IP, the new device features excellent EMC and ESD performance, optimized for low-cost LIN slave applications, and includes a powerful LIN UART with integrated hardware program. The amount of LIN code is reduced to approximately 1 kB of flash and minimizes the occurrence of interrupts.

Main features of ATA6617:

With LIN SBC

LIN transceiver, best-in-class electromagnetic compatibility (EMC) performance

Higher ESD levels on LIN, Wake, and Supply (VS) pins

Linear low dropout regulator

Window watchdog

Comply with LIN 2.0 and SAE J2602-2 standards

With AVR microcontroller

16 Kbyte flash

Hardware LIN UART

11 single-ended / 8-channel differential 10-bit ADCs

512-Byte true EEPROM

512-Byte internal SRAM

Low power mode

Multiple timers

The main advantage

PCB size requirements are minimal

Easy to use

Reduce overall system cost

Since the LIN protocol processing does not consume resources, the target application has the largest CPU resources and flash memory.

ATA6617 â€“ EK Development Board V1.1

The development board for the ATA6617 IC is designed to give designers a quick start with the ATA6617 IC and to enable prototyping and testing new LIN designs.

The ATA6617 is a dual-chip System-in-Package (SIP) product, which is especially suited for complete LIN bus slave and master 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 5V voltage regulator, a window watchdog, and a fully integrated LIN transceiver, in compliance with the LIN specification 2.1. The second chip is an automotive microcontroller from Atmel's series of AVR All-bit integrated chips are bonded out to provide customers the same flexibility for their applications as they have when using discrete parts.
