Overview

Zilog’s Z8 Encore! MCU family of products are the first in a line of Zilog microcontroller products based upon the 8-bit eZ8 CPU. Zilog’s Z8 Encore! XP F082A Series products expand upon Zilog’s extensive line of 8-bit microcontrollers. The Flash in-circuit pro gramming capability allows for faster development time and program changes in the field. The new eZ8 CPU is upward compatible with existing Z8 instructions. The rich peripheral set of the Z8 Encore! XP F082A Series makes it suitable for a variety of applications including motor control, security systems, home appliances, personal electronic devices and sensors.
