[原创] Atmel ATA6632xx LIN系统基础芯片(SBC)开发方案

Atmel公司的ATA663232/54系统基础芯片(SBC)是全集成了低压降电压稳压器(LDO)的LIN总线收发器,和LIN标准2.0, 2.1, 2.2, 2.2A和SAEJ2602-2兼容,电源电压高达40V,工作电压5V-28V,主要用于汽车低速数据通信.本文介绍了ATA663231/54主要特性,框图,典型应用电路,以及ATA663203和ATA663231/54开发板主要特性,电路图,材料清单和PCB设计图.

The Atmel® ATA6632xx device family includes two basic products; a LIN system basis chip (SBC) and a low-drop voltage regulator with compatible footprints.

The Atmel ATA663231/54 (system basis chip) is a fully integrated LIN transceiver, designed according to the LIN specification 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2, with a low-drop voltage regulator (3.3V/5V/85mA). The combination of voltage regulator and bus transceiver makes it possible to develop simple but powerful slave nodes in LIN bus systems.

Atmel ATA663231/54 is designed to handle the low-speed data communication in vehicles (for example, in convenience electronics). Improved slope control at the LIN driver ensures secure data communication up to 20Kbaud. The bus output is designed to withstand high voltage. Sleep mode and silent mode guarantee minimized current consumption even in the case of a floating or a short-circuited LIN bus.
