GENERAL DESCRIPTION
Zilog's Z86C02/E02/L02 microcontrollers (MCUs) are members of the Z8® single-chip MCU family, which offer easy software/hardware system expansion. For applications demanding powerful I/O capabilities, the MCU's dedicated input and output lines are grouped into three ports, and are configurable under software control to provide timing, status signals, or parallel I/O. One on-chip counter/timer, with a large number of user-selectable modes, off-load the system of administering realtime tasks such as counting/timing and I/O data communi-

This is a stress rating only; functional operation of the device at any condition above those indicated in the operational sections of these specifications is not implied. Exposure to absolute maximum rating conditions for an extended period may affect device reliability. Total power dissipation should not exceed 462 mW for the package. Power dissipation is calculated as follows: Total Power dissipation = VDD x [IDD – (sum of IOH)] + sum of [(VDD – VOH) x IOH] + sum of (V0L x I0L) Min –40 –65 –0.7 –0.3 –0.7 –0.7 Max +105 +150 +12 +7 VDD+1 VDD+1 462 300 270 +600 +600 20 20 80 80 Units C C V V V V mW mA mA µA µA mA mA mA mA
