Z86E04

Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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 powerdissipation should not exceed 462 mW for the package.

Power dissipation is calculated as follows:

Total Power Dissipation = V_DD x [I_DD - (sum of I_OH)]
+ sum of [(V_DD - V_OH) x I_OH]
+ sum of (V_0L x I_0L)

Zilog's Z86E04/E08 Microcontrollers (MCU) are One-Time Programmable (OTP) members of Zilog's single-chip Z8^® MCU family that allow easy software development, debug, prototyping, and small production runs not economically desirable with masked ROM versions.

For applications demanding powerful I/O capabilities, the Z86E04/E08'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.

Two on-chip counter/timers, with a large number of user selectable modes, offload the system of administering real-time tasks such as counting/timing and I/O data communications.
