Overview

Z8 Encore! XP® 4K Series

Product Specification

Overview

The Z8 Encore!® MCU family of products are the first in a line of ZiLOG® microcontrol-

ler products based upon the 8-bit eZ8 CPU. The Z8 Encore! XP® 4K 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 periph-

eral set of the Z8 Encore! XP® 4K Series makes it suitable for a variety of applications

including motor control, security systems, home appliances, personal electronic devices,

and sensors.
