51单片机及其应用:1.1.1 电子计算机的问世及其经典结构1946年2月15日，第一台电子数字计算机问世，这标志着计算机时代的到来。（CALCULATOR）ENIAC（“埃尼阿克”）◆ENIAC是电子管计算机，时钟频率仅有100 KHz，但能在1秒钟的时间内完成5000次加法运算。◆与现代的计算机相比，有许多不足，但它的问世开创了计算机科学技术的新纪元，对人类的生产和生活方式产生了巨大的影响 。 匈牙利籍数学家冯·诺依曼在方案的设计上做出了重要的贡献。1946年6月，他又提出了“程序存储”和“二进制运算”的思想，进一步构建了计算机由运算器、控制器、存储器、输入设备和输出设备组成这一计算机的经典结构。（EDVAC-ELECTRONIC DISCRETE VARIABLE AUTOMATIC COMPUTER）二、微型计算机的应用形态 从应用形态上，微机可以分成三种：

The PCA9535 and PCA9535C are 24-pin CMOS devices that provide 16 bits of GeneralPurpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and wasdeveloped to enhance the NXP Semiconductors family of I2C-bus I/O expanders. Theimprovements include higher drive capability, 5 V I/O tolerance, lower supply current,individual I/O configuration, and smaller packaging. I/O expanders provide a simplesolution when additional I/O is needed for ACPI power switches, sensors, push buttons,LEDs, fans, etc.

<Almost since the introduction of microcontrollers as electronic components there always has been an oscillatorcircuit on the device to make it work. From application point of view only some external components wererequired to make it work. However, to make sure that it will always work required more effort. This report is basedon feedback from the market from customers applying 8-bit mircrocontrollers.>
