为了嵌入式控制系统的使用,英特尔的新型口扩展电路把很多东西封装在一个小模块里:I/O口,永久性存储器和胶连逻辑都包含在一个塑料带引线芯片载体中。象系统中微处理器需要外设和存储器一样,标准单片机的系统也需要。在继续完善系统性能的同时,使用多通道技术来达到压缩系统尺寸的目的。最普通的方法就是将存储器集成到单片机中去。很多系统必须存储程序代码或应用软件,因此需要大于4k、8k或16k的R0M或EPR0M来附加到现在的8位和16位单片机上。这已经由
For use with embedded control systems, Intel’s new port expansion circuit packs a lot of things in a small module: I / O ports, permanent memory and glue logic are contained in a plastic leaded chip carrier. Like a microprocessor in a system that requires peripherals and memory, a standard microcontroller system is also needed. While continuing to improve system performance, the use of multi-channel technology to achieve the purpose of compression system size. The most common way is to integrate the memory into the microcontroller. Many systems must store program code or application software, so R0Ms or EPR0Ms larger than 4k, 8k, or 16k are required to attach to the current 8-bit and 16-bit microcontrollers. This has been by
