ZMOTION^® Intrusion Detection
Product Specification
1
Overview
The ZMOTION Intrusion Detection device is an integrated and flexible solution for Pas-
sive Infrared (PIR)-based motion detection applications. The ZMOTION family includes
a series of high-performance microcontrollers with integrated motion-detection algorithms
and a selection of lenses and PIR sensors to fit a wide range of intrusion detection and
security applications. Zilog’s ZMOTION Intrusion Detection Solution provides a dra-
matic improvement in both sensitivity and stability over traditional security-related
motion detection designs with integrated functions such as White Light detection and Pet
Immunity. As a result, it is the ideal solution for security applications in which intrusion
detection capability is vital.
The ZMOTION Intrusion Detection Solution, based on Zilog’s Z8FS021 MCU, combines
the programmability and rich peripheral set of our Z8 Encore! XP family of In-Circuit
Programmable Flash MCUs with built-in motion detection software algorithms to provide
the functions necessary for PIR motion detection applications. These algorithms comprise
the PIR Engine and run in the background while control and status of the Engine is
accessed through a software Application Programmer Interface (API). These APIs allow
designers to create their own application-specific software while taking advantage of
Zilog’s ZMOTION Motion Detection Technology. Additional API settings are provided
to match PIR Engine operation to each lens and pyroelectric sensor combination.
The Flash in-circuit programming capability of the Z8FS021 MCU allows for faster devel-
opment time, more flexible manufacturing and firmware changes in the field.
As with all of Zilog’s ZMOTION products, the ZMOTION Intrusion Detection MCU pro-
vides optimized configuration parameters for each lens/sensor combination to ensure the
best possible performance while significantly reducing development risk and minimizing
time to market.
