ZMOTION® Intrusion Motion Detection Solution
Simple and Superior PIR Motion Detection Solutions for Intrusion/Security Applications
Zilog’s ZMOTION Intrusion Motion Detection product family is an integrated and flexible solution for
Passive Infrared (PIR)-based intrusion/security motion detection applications. It includes a high-
performance microcontroller with integrated PIR motion-detection S/W algorithms and a selection of
lenses and PIR sensors to fit a wide range of intrusion motion detection applications. These PIR motion-
detection algorithms – called the ZMOTION Engine – are pre-programmed in the device and provide all
motion sensing functions plus White Light Detection, Pet Immunity, and EMI Rejection. Using statistical
processing methods, the ZMOTION
Engine provides a dramatic
improvement in both sensitivity and
stability over traditional PIR motion
detection designs while eliminating
the need for external temperature
compensation. Also, the pyroelectric
sensor is interfaced directly to the
MCU without filtering, allowing for
better detection of EMC events
associated with false detections and
eliminating the need for external op-
amps, electrolytic capacitors and
other discrete components used in
traditional designs. These features lead to a simpler and smaller circuit design, providing better reliability,
sensitivity, and stability than traditional designs. The ZMOTION Intrusion Detection Solution is the ideal
solution for security applications in which highly stable intrusion detection capability is vital.

ZMOTION Engine
The ZMOTION Engine is at the heart of the ZMOTION MCU. This pre-programmed Firmware performs all
of the motion detection functions in addition to White Light Detection and EMI filtering. An API is
provided to control and monitor the Engine in real time. The API also allows the Engine to be tuned the
specific lens (wide angle, long range, vertical barrier, etc.) and pyro-electric sensor (typically dual element
or quad element) being used in the application. This means that changing lenses is just a matter of
changing the API settings – no changes to external circuitry. Zilog provides a range of pre-tested settings
for all of the lenses we provide. These optimized configuration parameters provided for each lens/sensor
combination ensures the best possible performance while significantly reducing development risk and
minimizing time to market.
Add your custom application code to control and monitor the Engine and drive the appropriate outputs.
Use the application code from our reference design or modify it to meet your specific application
requirements.
The ZMOTION Engine performs the following functions:
•
PIR Motion Detection
•
White Light Detection
•
White Light Anti-Jam
•
Anti-Jam
•
1 or 2 Pulse Mode
•
ADC interface

ZMOTION Lenses
The ZMOTION Intrusion Detection solution includes a selection of 3 Fresnel lenses matching the
requirements of most intrusion detection applications. Lens options include a Wide Angle typically used in
corner/wall mount detectors, a Long Range for hallways, and a Vertical Barrier for curtain type detectors.
API settings are provided to match the ZMOTION Engine operation to each lens type, ensuring the best
possible performance while significantly reducing development risk and minimizing time to market. The
flexibility of the ZMOTION Engine also allows you to use your own lens and pyroelectric sensor if desired.
