ATA664251 [DATASHEET]

Description

Atmel® ATA664251 is a system-in-package (SiP) product, which is especially well suited for complete LIN-bus node

applications. It is designed specifically for LIN switch applications and includes nearly the entire LIN node. The Atmel

ATA664251 consists of two ICs in one package supporting highly integrated solutions for in-vehicle LIN networks. The first

chip is the Atmel ATA664151 LIN system basis chip (LIN-SBC), which has an integrated LIN transceiver, a 5V regulator

(80mA), a window watchdog, an 8-channel high-voltage switch interface with high-voltage current sources and a 16-bit SPI

for configuration and diagnosis.

The second chip is an automotive microcontroller from the AVR® 8-bit microcontroller series from Atmel with advanced RISC

architecture and the Atmel ATtiny167 with 16-Kbyte flash memory.

All pins of the LIN-SBC as well as all pins of the AVR microcontroller are bonded out to provide customers the same flexibility

for their applications they are accustomed to when using discrete parts.

In Section 2. “Pin Configuration” on page 3 contains the pin configuration for the complete SiP. The Section 4. “LIN System

Basis Chip (LIN-SBC) Block” on page 7 describes the LIN-SBC, and Section 5. “AVR Microcontroller Block” on page 45

describes the AVR microcontroller.
