ZSTAR3 Accelerometer Family Expansion
Multiple wireless sensing triple-axis reference design
Overview
MMA7660FC ZSTAR3
The ZSTAR3 system accommodates multiple
digital and analog accelerometer boards,
connected through an RF ZigBee® 2.4 GHz
MMA7660FC 3 x 3 x 0.9 mm DFN
or MMA7361L triple-axis analog
accelerometer 3 x 5 x 1 mm LGA

communication to a single USB node connected
to a PC. The accelerometer boards measure
acceleration in three axes using a pin compatible
digital or, optionally, an analog sensor. The
sensor sensitivity is defined by the selected
accelerometer. The USB node is part of the
ZSTAR design, equipped with dedicated software
supporting multiple nodes.

Freescale is now offering the next-generation
ZSTAR3 with the MMA7660FC accelerometer
that offers extended functionality. The new PC
software showcases the built-in intelligence of
the MMA7660FC for consumer applications with
orientation, shake, tap detection, auto-wake and
auto-sleep. The ZSTAR3 is a small portable
board design that utilizes the following products:
