Description

Z86E0812PSG is an electronic component model belonging to the microcontroller category. It is part of Zilog's Z8® MCU family, specifically designed for easy software development, debug, prototyping, and small production runs. Unlike masked ROM versions, this model is one-time programmable (OTP), providing flexibility for various applications.

The Z86E0812PSG features dedicated input and output lines grouped into three ports, which can be configured under software control to provide timing, status signals, or parallel I/O. It also includes two on-chip counter/timers with a wide range of selectable modes to handle real-time tasks, such as counting/timing and I/O data communications.
