This CMOS microcontroller features fast execution, efficient use of memory, sophisticated interrupts, input/ output bit manipulation capabilities, and easy hardware/ software system expansion along with low-cost and low-power consumption. For applications demanding powerful I/O capabilities, the Z86160 fulfills this with custom I/O, specifically tailored to meet the needs of set-top requirements. Four basic address spaces, the Program Memory, Data Memory, 236 General-Purpose Registers, and 512 bytes of protected RAM, support a wide range of memory configurations. The protected RAM is mapped into data memory. To unburden the program from coping with real-time problems such as counting/timing, and serial data communications, the Z86160 offers two on-chip counter/timers with a large number of user selectable modes, and an asynchronous r...
