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
