引言 RUPI—44系列是专门为要求远程节点智能化,节点间具有通讯能力的分布应用而设计的。RUPI—44将Intel高性能微控制器、8051单片机与一个智能串行通讯控制器,即串行接口部件SIU集成于一体,见图1。这种双控制器结构允许更有效地实现复杂的控制和高速数据通讯能力。 RUPI—44系列有三类; ·8344——带有SIU的8051微控制器。·8044——带有4K字节片上ROM程序存贮器的8344。·8744——带有4K字节片上EPROM程序存贮器的8344。
Introduction The RUPI-44 series is specifically designed for distributed applications that require remote nodes to be intelligent and have communication capabilities between nodes. The RUPI-44 combines an Intel high-performance microcontroller, the 8051 microcontroller with an intelligent serial communications controller, the serial interface unit SIU, as shown in Figure 1. This dual-controller architecture allows for more complex control and high-speed data communication capabilities. There are three types of RUPI-44 series; · 8344 - 8051 microcontroller with SIU. 8044 - 8344 with 4K bytes on-chip ROM program memory. 8744 - 8344 with 4K bytes on-chip EPROM program memory.
