The only differentiating factor between these two versions is the availability of ROM. Zilog's CMOS microcontrollers offer fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, automated pulse generation/reception, and easy hardware/software system expansion along with cost-effective and low power consumption. The Z86L7X architecture is based on Zilog's 8-bit microcontroller core with an Expanded Register File to allow access to register mapped peripherals, I/O circuits, and powerful counter/timer circuitry. The Z8® MCU offers a flexible I/O...
