介绍几种cpuThe 8xC251SA/sb/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture i.e., the MCS 251 microcontroller architecture. The register based CPU supports a 40-byte register file. In addition, the 8xC251SA/sb/SP/SQ microcontroller has 256-Kbyte expanded external code/data memory space and 64-Kbyte stack space. The new controller is also specially designed to execute C code efficiently. More importantly, the 8xC251SA/sb/SP/SQ maintains binary code compatibility with MCS 51 microcontrollers but at the same time allows the use of the powerful MCS 251 microcontroller instruction set, with many new 8, 16 and 32 bit instructions available. The 8xC251SA/sb/SP/SQ has 512 bytes or 1 Kbyte of on-chip data RAM options and is available in 16 Kbytes and 8 Kbytes of on-chip ROM/OTPROM or ROMless options.

若锗中含有一定数量的杂质元素sb,试根据要求分析杂质浓度与电离度以及电离温度之间的关系: (1)当sb浓度分别为 和 时,计算杂质99%,90%和50%电离时的温度各为多少? (2)根据一定杂质类型和杂质浓度,画出电离度和温度的关系图线,并确定半导体处于强电离区(电离度>90%)的温度范围。 设计要求:(1)具有友好输入输出界面; (2)调整输入数据,得出相应结果,并进行分析。
