Zilog’s Z86C02, Z86E02, and Z86L02 microcontrollers are members of Zilog´s Z8® single-chip MCU family, which offers easy software/hardware system expansion. One on-chip counter/timer, with a large number of user-selectable modes, offloads the administration of real-time tasks, such as counting/timing and I/O data communications. Additionally, two onboard comparators process analog signals with a common reference voltage.
