DEVELOPMENT AND EVALUATION KITS
Freescale will provide development and evaluation kits for all sensor products. The RD3152MMA7260Q ZigBee sensing triple-axis reference (ZSTAR) design demonstrates the latest innovations from Freescale using 2.4-GHz wireless connectivity, a three-axis sensor, and embedded flash microcontrollers.
The development tool contains the MC9S08QG8 MCU, combined with the MMA7260Q XYZ-axis accelerometer, which can be directly replaced with the MMA6270Q, MMA6280Q, or MMA7261Q. A 2.4-GHz wireless transceiver and an interface for USB 2.0 full-speed are included as well.
Evaluation kits are also available for the three MEMS-based sensors. Small circuit boards can be used to evaluate the devices to quickly develop prototypes. In addition, the E-field sensor evaluation kit contains the evaluation board, a driver CD-ROM, connectors, and program software.
The sensors are available in production quantities. Suggested price in 25,000-piece quantities starts at $3.58 each for the MMA6270Q, $3.85 each for the MMA6280Q, and $4.43 each for the MMA7261Q. In high volumes, suggested product pricing is less than $2 each. The 24-pin wide small-outline IC MC34940 E-field sensor costs $1.85 each in 10,000-unit lots. Evaluation kits are priced at $35 each.
