Atmel ATA664251 LIN总线系统开发方案
Atmel公司的ATA664251是系统级封装(SiP)器件,包括LIN系统基础芯片(LIN-SBC),它集成了LIN收发器,5V稳压器(80mA),窗口看门狗,带高压电流源的8路高压开关接口和用于配置和诊断的16位SPI;以及带有16KB闪存的AVR 8位汽车微控制器Atmel ATtiny167.电源电压高达40V,工作电压5-27V,工作温度–40℃ 到+125℃,主要用LIN节点.本文介绍了ATA664251一般特性和主要特性,框图,框图和多种典型应用电路,以及Atmel® ATA664251开发套件和PC接口板主要特性,电路图,PCB元件布局图,设计图和材料清单.
Atmel® ATA664251 is a system-in-package (SiP) product, which is especially well suited for complete LIN-bus nodeapplications. It is designed specifically for LIN switch applications and includes nearly the entire LIN node. The AtmelATA664251 consists of two ICs in one package supporting highly integrated solutions for in-vehicle LIN networks. The firstchip 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 SPIfor configuration and diagnosis.
The second chip is an automotive microcontroller from the AVR® 8-bit microcontroller series from Atmel with advanced RISCarchitecture and the Atmel ATtiny167 with 16-Kbyte flash memory.
