ST7529液晶驅動 The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255 Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts serial Peripheral Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.

Ideal for large low power (nanoWatt) and connectivity applications that benefit from the availability of four serial ports: double synchronous serial ports (I² C™ and SPI™ ) and double asynchronous (LIN capable) serial ports. Large amounts of RAM memory for buffering and FLASH program memory make it ideal for instrumentation panels, TCP/IP enabled embedded applications as well as metering and industrial control and monitoring applications. While operating up to 40 MHz, it is also backward software and hardware compatible with the PIC18F8720.

通用串行總線(USB)是一種新興的計算機外圍串行通信接口標準，與常用的計算機接口(如串口、并口等)相比，通用串行總線(Universal serial Bus，USB)具有熱插拔、即插即用、數據傳輸可靠、擴展方便、低成本等優點。從問世以來，它得到了廣泛的應用，一方面已成為當前計算機必備的接口之一，同時也被廣泛地應用于嵌入式系統設計中。 從1994年USB 0．7出現開始，USB實施者論壇(Implementation Forum)先后定義了USB 0．8、0．9、1．0、1．1、2．0以及USB OTG等規范，以及各種不同的設備類規范。其中USB1．1規范目前正逐步廣泛應用，而USB2．0和USBOTG作為USB協議的更新和擴展，也將使USB占領更廣的外設

NAME Control_AT24Cxx This collection of routines allows an AT89C2051 microcontroller to read and write the AT24Cxx family of serial CMOS EEPROMS. This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051. Note that the minimum size of the buffer is determined by the page size of the AT24Cxx.

2001年春季的IDF上Intel正式公布PCI Express，是取代PCI總線的第三代I\O技術，也稱為3GIO。該總線的規范由Intel支持的AWG（Arapahoe Working Group）負責制定。2002 年4月17日，AWG正式宣布3GIO 1.0規范草稿制定完畢，并移交PCI-SIG進行審核。開始的時候大家都以為它會被命名為serial PCI（受到串行ATA的影響），但最后卻被正式命名為PCI Express。2006年正式推出Spec2.0（2.0規范）
