Z8FS040 Datasheet, PDF (6/56 Pages) Zilog, Inc. – ZMOTION Detection and Control Family Featuring Zilog’s PIR Technology

ZMOTION^TM Detection and Control Family
Product Specification
Overview
Zilog’s ZMOTION^TM Detection and Control Product Family provides an integrated and flexible solution
for Passive Infra Red (PIR) based motion detection applications. The 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 application requirements. Optimized configuration parameters
for the MCU are provided for each lens/sensor combination ensuring the best possible performance
while significantly reducing development risk and minimizing time to market.
The Z8FS040 ZMOTION^TM Detection MCU combines the programmability and rich peripheral set of
Zilog’s Flash Z8F082A Z8 Encore! XP^® MCU with built-in motion detection software algorithms to
provide the functions necessary for PIR motion detection applications. These motion detection
algorithms comprise Zilog’s PIR technology and run in the background while control and status of the
Engine is accessed through a software API (Application Programmer Interface). This allows the
designer to create their own application specific software while taking advantage of Zilog’s
ZMOTION^TM Motion Detection Technology.
API settings are provided to match the Engine operation to each of the lens and pyroelectric sensor
combinations provided.
The Flash in-circuit programming capability of the Z8FS040 allows for faster development time, more
flexible manufacturing and firmware changes in the field.
Zilog’s PIR motion detection technology provides a dramatic improvement in both sensitivity and
stability over traditional designs and is scalable to many market segments including Lighting Control,
HVAC, Access Control, Vending, Display, Proximity, Power Management, Occupancy Sensing and
many others.
