ADI ezLINX iCoupler绝缘接口开发方案

ADI 公司的ezLINX iCoupler绝缘接口开发平台采用ADSP-BF54x Blackfin系列处理器,用来评估八种物理层数字绝缘的通信标准(USB, RS-422, RS-485, RS-232, CAN, SPI, I2C 和LVDS),由于Blackfin ADSP-BF548处理器运行在uCLinux操作系统,很容易通过开源硬件和软件平台实现个性化,大大缩短了开发时间,ezLINX上的接口ezLINX采用ADI的绝缘收发器.本文介绍了ADSP-BF54x主要特性,方框图,ezLINX iCoupler绝缘接口开发平台主要特性,框图,电路图和材料清单.
The ADSP-BF54x Blackfin® processors are members of the Blackfin family of products, incorporating the Analog Devices/ Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set Architecture.
LOW POWER ARCHITECTURE
Blackfin processors provide world-class power management and performance. Blackfin processors are designed in a low power and low voltage design methodology and feature on-chip dynamic power management, the ability to vary both the voltage and frequency of operation to significantly lower overall power consumption. Reducing both voltage and frequency can result in a substantial reduction in power consumption as compared to reducing only the frequency of operation. This translates into longer battery life for portable appliances.
SYSTEM INTEGRATION
The ADSP-BF54x Blackfin processors are highly integrated system-on-a-chip solutions for the next generation of embedded network connected applications. By combining industrystandard interfaces with a high performance signal processing core, users can develop cost-effective solutions quickly without the need for costly external components. The system peripherals include a high speed USB OTG (On-the-Go) controller with integrated PHY, CAN 2.0B controllers, TWI controllers, UART ports, SPI ports, serial ports (SPORTs), ATAPI controller, SD/SDIO controller...
