Freescale MMA7660FC ZSTAR3 Tool Enables Quick Wireless Sensor Design



ZSTAR3 reference design offers extended functionality for consumer applications with built-in power cycling, orientation, shake and tap features

MMA7660FC ZSTAR3 wireless sensor tool with built-in power cycling, orientation, shake and tap features

AUSTIN, Texas - Freescale Semiconductor has introduced an addition to its popular ZigBee® wireless sensing triple-axis reference (ZSTAR) demonstration tool collection. The newest offering features the MMA7660FC triple-axis accelerometer, which enhances user interfaces with intelligent features for mobile phones, small appliances and gaming. The accelerometer has built-in intelligence for consumer applications with orientation, shake and tap detection. It also includes smart power management features such as auto-wake and auto-sleep to help extend battery life.

The advanced RD3965MMA7660FC ZSTAR3 reference design provides designers with two small, portable demo boards, a sensor transceiver board and a USB receiver board for demonstrating and evaluating a wide range of accelerometer-based applications with low-power wireless connectivity. A USB stick connects via the computer's USB port for communications, using Freescale's USB 2.0 full-speed 8-bit MC68HC908JW32 microcontroller (MCU).

Wireless communication is enabled by Freescale's MC13213, a ZigBee-ready 2.4GHz low-power transceiver that also contains an 8-bit MCU as a system-in-package that reduces board space requirements.

The MC13213 ZigBee platform is an IEEE 802.15.4 standard compliant on-chip transceiver/modem that is capable of 16 selectable channels. For more information, visit www.freescale.com/zigbee.
