The differentiating factor between these devices is the availability of RAM, ROM and package options. The use of external memory enables these Z8 microcontrollers to be used where code flexibility is required. Offering the 5V versions (Z86CXX) and gives optimum performance in both the low and high voltage ranges. Zilog's CMOS microcontrollers DS97LVO0900 offer fast execution, efficient use of memory, sophisticated interrupts,...
