随着LSI技术的不断进步,于1978年实现了将CPu、RAM、ROM和I/0接口集成在一个芯片中,从而使其成为一个完整的单片微型机。单片机存贮容量较少,适合用于规模不大的专用控制。其成本比板级系统大为降低,体积亦显著减少,可以直接装在所控设备上,使用十分方便。因此,美国三大半导体厂家、Intel、zilc:及Moto1’。扭分别推出了自己的产品系列M〔S一48、28及6eOI。每个系列中又包括不同产品,这些产品具有CFU,但存贮器容量及I/0口个数不尽相同,适于不同应用的需要。
With the continuous improvement of LSI technology, the CPu, RAM, ROM and I / O interfaces were integrated into a single chip in 1978, making it a complete single-chip microcomputer. Microcontroller less storage capacity, suitable for small-scale dedicated control. The cost is much lower than the board system, the volume is also significantly reduced, can be directly installed in the controlled equipment, easy to use. Therefore, the three major semiconductor manufacturers in the United States, Intel, zilc: and Moto1 ’. Twisted launched their own product line M 〔S a 48,28 and 6eOI. Each series also includes different products, these products have CFU, but the memory capacity and the number of I / O port varies, suitable for different applications.
