MC 6801 U 4是8位单片微型计算机器件,它显著地提高了 MC 6800系列部件的性能。它包括一个MC6801微处理器,具有与MC6800源代码和目的码向上兼容。其关键指令的执行时间已超过MC6800,并增加了一些新指令。该微计算机可用作一个独立的微机或可以扩充到64K字带的地址空间。它同TTL兼容,需要一个5V电源。芯片容量包括4096字节ROM,192字节RAM一个串行通讯接口,一个并行I/O接口和一个16位6功能可编程序的定时器。
The MC 6801 U 4 is an 8-bit monolithic microcomputer device that significantly improves the performance of the MC 6800 Series components. It includes an MC6801 microprocessor with upward compatibility with the MC6800 source code and destination code. The execution time of its key instructions has exceeded that of the MC6800 and some new instructions have been added. The microcomputer can be used as a stand-alone microcomputer or can be expanded to 64K words of address space. It is TTL-compatible and requires a 5V power supply. Chip capacity includes 4096 bytes of ROM, 192 bytes of RAM, a serial communication interface, a parallel I / O interface and a 16-bit programmable 6-function timer.
