TI TIDA－01425带以太网和CAN的汽车网关参考设计
TI公司的TIDA-01425是基于DRA710信息娱乐应用处理器的带以太网和CAN的汽车网关参考设计,具有100BASE-T1汽车以太网,100BASE-TX和CAN PHYs,可以通过冷启动,抢跑和甩负荷等方式工作,降低EMI功率级和电池接反保护,能增加带宽和网关的处理能力,主要用在应用处理器模块,汽车网关,构建设备控制单元,自由空间传感器,铁路运输马达控制以及车辆乘员检测传感器.本文介绍了DRA710信息娱乐应用处理器主要特性和框图,汽车网关参考设计TIDA-01425主要特性,框图,电路图,材料清单和 PCB设计图.
The DRA71x processor is offered in a 538-ball, 17×17-mm, 0.65-mm ball pitch (0.8mm spacing rules canbe used on signals) with Via Channel™ Array (VCA) technology, ball grid array (BGA) package.The architecture is designed to deliver high-performance concurrencies for automotive applications in acost-effective solution, providing full scalability from the DRA75x ("Jacinto 6 EP" and "Jacinto 6 Ex"),DRA74x "Jacinto 6" and DRA72x "Jacinto 6 Eco" family of infotainment processors, including graphics,voice, HMI, multimedia and smartphone projection mode capabilities.
Programmability is provided by a single-core ARM Cortex-A15 RISC CPU with Neon™ extensions and aTI C66x VLIW floating-point DSP core. The ARM processor lets developers keep control functionsseparate from other algorithms programmed on the DSP and coprocessors, thus reducing the complexityof the system software.
