OVERVIEW
ZiLOG’s Z8 Encore!® family of high performance
microcontrollers redefines the 8-bit embedded solutions
market. Leading the competition with its robust feature
set, this family offers the flexibility and high performance
necessary to tackle the demanding applications that
design engineers face today.
With up to 64KB of program memory, software code can
be changed, updated, and reprogrammed during
development and into production. Contributing to this
highly integrated design is a 10-bit A/D converter, an on-
chip debugger, up to 24 interrupts, and up to 60 general-
purpose I/O pins.
High performance is achieved through the Z8 Encore!®
MCU’s 20MHz CPU core speed. Performance is further
enhanced with a 3-channel DMA controller (16-64KB
parts only) and up to 4KB of RAM. Additionally, the
option of running the I
2
C, SPI, and up to two UARTs in
parallel, and the inclusion of up to four 16-bit timers with
PWM capability, dramatically improves the flexibility
provided by this MCU family.
This next generation product, accompanied by an
exceptional development tool kit, provides a
comprehensive solution for programming needs.
Simplify your development process and increase design
productivity with ZiLOG's family of Z8 Encore!®
microcontrollers. Incorporating into new designs, or
upgrading from the existing Z8® architecture, the Z8
Encore!® MCU provides unbeatable value.
