Sensors ZSTAR3 Accelerometer Family Expansion Multiple wireless sensing triple-axis reference design Overview The ZSTAR3 system accommodates multiple MMA7660FC ZSTAR3 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 MC13191 MC13213 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. Buttons 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 LED the MMA7660FC for consumer applications with orientation, shake, tap detection, auto-wake and auto-sleep.
