LISY300AL

STMicroelectronics has introduced the LISY300AL, a 7mm x 7mm x 1.5mm surface-mount MEMS single-axis yaw gyroscope for angular rate sensing up to 300/s (full scale).

The new device combines high sensitivity, an extended supply voltage range, from 2.7V to 3.6V, and a selectable power-down mode. It also provides reduced standby power for applications such as game controllers, intuitive pointers, vehicle or personal navigation, and image stabilization.

Drawing on the company's expertise in MEMS, and combined with highly robust MEMS technology, the LISY300AL exhibits stable sensitivity and bias-voltage throughout variations in temperature and over the device's lifetime. This simplifies design and promotes reliable operation. Also featuring a co-integrated low-pass filter and dedicated IC interface, the LISY300AL enables a compact, low-noise solution using minimal external components. In addition, high survivability of shock and vibration allows use in demanding environments including industrial and automotive systems. An embedded self-test function provides extra assurance of accuracy and reliability.

In addition to consumer and industrial applications, including gaming and smart user interfaces for advanced pointing devices, the LISY300AL can be used for tilting and angular motion detection in robotics and assisted-GPS navigation systems.

The LISY300AL generates an absolute-rate output as an analog voltage. The 28-lead LGA device uses ST's ECOPACK packaging, which meets green criteria for RoHS compliance.

Samples of the LISY300AL are available immediately, with production volumes scheduled for introduction in Q3 08 at prices from $2.50.
