Atmel ATA664151 LIN系统基础芯片(SBC)开发方案
Atmel公司的ATA664151是集成了和LIN 2.1以及SAEJ2602-2兼容的LIN收发器,5V稳压器,看门狗,带高压电流源的8路高压开关接口和16位SPI的LIN系统基础芯片(SBC),工作电压5V-27V,电源电压高达40V,LIN高速模式速率高达200kBit/s,具有极好的EMC和ESD性能,主要用在汽车中LIN开关和LIN节点.本文介绍了ATA664151主要特性,框图,典型应用电路以及评估板ATAK42001-V1主要特性,电路图,材料清单和PCB元件布局图.
The Atmel® ATA664151 is a system basis chip with an eight-channel high voltage switch interface, a LIN 2.1 and SAEJ2602-2-compliant LIN transceiver, low-drop voltage regulator, and an adjustable window watchdog. The Atmel ATA664151 provides 5V output voltage with up to 80mA current capability. This chip combination makes it possible to develop inexpensive, simple, yet powerful slave and master nodes for LIN bus systems.
The Atmel ATA664151 is especially designed for LIN switch applications and includes almost the entire LIN node. They are designed to handle low data-rate communication in vehicles (such as in convenience electronics). Improved slope control at the LIN driver ensures secure data communication up to 20kBaud. Sleep Mode and Active Low-power Mode guarantee minimal current consumption even in the case of a floating bus line or a short circuit on the LIN bus to GND.
