  • 1A SIMPLE STEP-DOWN SWITCHING

    The TL2575 and TL2575HV represent superior alternatives to popular three-terminal linear regulators. Due totheir high efficiency, the devices significantly reduce the size of the heatsink and, in many cases, no heatsink isrequired. Optimized for use with standard series of inductors available from s ...

  • Adding 32 KB of Serial SRAM to

    Although Stellaris microcontrollers have generous internal SRAM capabilities, certain applicationsmay have data storage requirements that exceed the 8 KB limit of the Stellaris LM3S8xx seriesdevices. Since microcontrollers do not have an external parallel data-bus, serial memory optionsmust be consi ...

  • PCA954X家庭的I C SMBus多路复用器与开关

    The Philips family of Multiplexers and Switches consists of bi-directional translating switches controlled via the I2C or SMBus to fan out an upstream SCL/SDA pair to 2, 4 or 8 downstream channels of SCx/SDx pairs. The Multiplexers allow only one downstream channel to be selected at a time, while th ...

  • 一种8位单片机中ALU的改进设计

    文章提出了一种精简指令集8 位单片机中, 算术逻辑单元的工作原理。在此基础上, 对比传统PIC 方案、以及在ALU 内部再次采用流水线作业的332 方案、44 方案, 并用Synopsys 综合工具实现了它们。综合及仿真结果表明, 根据该单片机系统要求, 44 方案速度最高, 比332 方案可提高43.9%, 而面积仅比最小的332 方案增加1.6%。在分析 ...

  • Emulating a synchronous serial

    The C500 microcontroller family usually provides only one on-chip synchronous serialchannel (SSC). If a second SSC is required, an emulation of the missing interface mayhelp to avoid an external hardware solution with additional electronic components.The solution presented in this paper and in the a ...
