MCU Family
Low Cost 8-bit Microcontrollers
Triple Temperature Range Support
Standard temperature range is recommended for low
cost applications requiring a typical 0° to 70°C
temperature range. Extended temperature range (-40°
to 105°C) is intended for applications under more
severe conditions, and automotive temperature range
(-40° to 125°C) is the ideal choice for automotive
applications.
Features
• Up to 32KB of program memory (EPROM/OTP
or ROM)
• Up to 237 Bytes of RAM
• 8MHz CPU core
• Up to 32 General Purpose I/O
• Two independent comparators
• Low voltage (2.0-3.6V) and high voltage
(2.0-5.5V) versions
• Low power consumption (6mW typical)
• One 8-bit counter/timer
• One 16-bit counter/timer
• Special counter/timer architecture to automate
generation and reception of complex pulses and
signals. Includes a programmable input glitch filter.

• Power-On Reset (POR)
• Multiple temperature ranges:
o Standard (0° to +70°C)
o Extended (-40° to +105°C)
o Automotive (-40° to +125°C)
• Available in SOIC, SSOP, and PDIP packages
Overview
Looking for a low cost 8-bit microcontroller? Look no
further. ZiLOG's Z8 GP™ general purpose
microcontrollers are offered in a wide range of
memory sizes, voltage ranges, and temperature
ranges to give you the ability to choose just the right
combination of features that your end application
requires. Based on the popular Z8® register to
register architecture, the Z8 GP™ MCUs will make
your design process easy. Development is further
simplified by affordable development tools which are
easy to use and contain a full version ANSI C
Compiler at no additional cost.
Wide Operating Voltage Range
The Z8 GP™ MCU family gives you greater design
flexibility. The low-voltage series (ZGP323L,
ZGR323L, and ZGR163L devices) support voltage
ranges from 2.0 to 3.6V and are ideal for low-power
applications. The high-voltage series (ZGP323H
devices) operate at 2.0 to 5.5V for applications
requiring a wide voltage range.
Multiple Memory Sizes
Z8 GP™ microcontrollers are offered in program
memory sizes up to 32KB. One-time programmable
(OTP) versions are available in 4KB to 32KB memory
sizes and ROM versions are available in 1KB to 32KB
memory sizes.
