Invensense(TM) Unveils World's First Imu Solution With 6-Axis Sensor Fusion For Consumer Applications
IMU-3000(TM) Features On-Board 3-Axis Digital Gyroscope that Integrates Accelerometer Inputs to Provide Complete 6-Axis Sensor Fusion Output
Motion command is becoming a standard interface in the consumer electronics industry. Because of this feature, sales of Nintendo's Wii in 2009 grew to account for a 43 percent share of video game consoles shipped in 2009, prompting Sony and Microsoft to introduce motion sensing game play solutions in time for the holiday season this year, according to Pam Tufegdzic, consumer electronics analyst at the market research firm iSuppli Corp., El Segundo, Calif.
"While the combination of the 3-axis accelerometer with a 3-axis gyroscope provides much fuller and more accurate recognition of user motion than an accelerometer alone, the task of fusing the signals from both sensors is everything but trivial," said Jérémie Bouchaud, principal analyst for MEMS and sensors at iSuppli. "A solution that can process both types of signals will ease the work for the OEM and contribute to accelerating adoption in gaming, as well as other consumer applications, like IPTV remotes."
The IMU-3000 features a 3-axis digital gyro with programmable fullscale ranges of ±250, ±500, ±1000, and ±2000 degrees/sec, which is useful for precision tracking of both fast and slow motions. Rate noise performance sets the industry standard at 0.02 degrees/sec per ?Hz, providing the highestquality user experience in pointing and gaming applications. Factorycalibrated initial sensitivity of 1% reduces productionline calibration requirements. The part's onchip FIFO and dedicated I2Cmaster accelerometer sensor bus simplify system timing and lower system power consumption; the sensor bus allows the IMU-3000 to directly acquire data from the offchip accelerometer without intervention from an external processor. Other industryleading features include a small 4mmx4mmx0.9mm plastic QFN package, onchip16bit ADCs, programmable digital filters, a precision clock with 2% accuracy over -40°C to 85°C, an embedded temperature sensor, programmable interrupts, and a low 13mW power consumption. Parts are available with I2C and SPI serial interfaces, a VDD operating range of 2.1 to 3.6V, and a VLOGIC interface voltage from 1.71V to 3.6V.
"The IMU-3000 addresses the market need for a complete solution to address motion processing in a wide range of applications without adding system processing overhead,"
said Michael Maia, Vice President, InvenSense Gaming and 3D User Interface Business Unit. "By driving the processing into the device, the IMU-3000 enables a low power, low cost solution that can now be easily integrated with significant timetomarket improvements."
The key enabling technology behind the size and high performance of the IMU-3000 is the company's patented and volumeproven Nasiri-Fabrication platform, which directly integrates MEMS mechanical structures and CMOS electronics at the wafer level enabling the industry's lowest noise specification, lowest power consumption, and smallest package size. Leveraging its 8" fabrication platform and its inhouse high volume test and calibration facilities in Taiwan, the IMU-3000 is designed to support the high volume requirements of the consumer marketplace.
The IMU-3000 family is available now for sampling by select qualified customers with mass production in Q2 2010 and is priced at under $3.50 for high volume applications.
