MC9S08QG8英文资料 The MC9S08QG8 is the newest member of the Freescale 8-bit family of highly integratedmicrocontrollers, based on the high-performance yet low power HCS08 core. The MC9S08QG8is an excellent solution for power-sensitive applications with extended battery life and maximum performance d ...

The main oscillator allows either a crystal or single-ended input clock signal. Cost-sensitiveapplications typically use an external crystal with the on-chip oscillator circuit since it is the mostcost-effective solution. It is also possible to use the internal oscillator to clock the device after t ...

The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are orientedin the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic inputand output buffer separated by TI’s silicon-dioxide (SiO2) isolation barrier ...

摘要：本水位监测报警器使用5V低压直流电源（也可以用3节5号电池代替）就可以对5~15厘米的水位进行监测，用LED显示和数码管显示水位，并可以对不再此范围内的水位发出报警。主要采用CD4066、74LS86、74LS32、CD4511芯片，再加上数码管、蜂鸣器、发光二极管、电阻这些器件组成一个简单而灵敏的监测报警电路，操作简单，接通 ...

As businesses and consumers expect more fromportable electronics, the FPGA industry has beencompelled to re-think how it serves these low-power,cost-sensitive markets. Application classes like

  FPGAs have changed dramatically since Xilinx first introduced them just 15 years ago. In thepast, FPGA were primarily used for prototyping and lower volume applications; custom ASICswere used for high volume, cost sensitive designs. FPGAs had also been too expensive and tooslow for many a ...

位置敏感探测器PSD（Position Sensitive Detector PSD）具有位置分辨精度高（可达1～2 μm）、输出实时性好（响应时间约几微秒）、系统简洁的特点，在位置探测及相关领域内获得了广泛的应用；但PSD的输出信号小，易受到电路噪声的影响，若要充分发挥其性能，则需要高精度、高稳定度、低噪声的测量电路。针对PSD这种较高的 ...

ICA is used to classify text in extension to the latent semantic indexing framework. ICA show to align the context grouping structure well in a human sense [1], thus can be used for unsupervised classification. The demonstration shows this on medical abstracts (MED dataset), that uses BIC to estimat ...
