Yamaha Corporation announced that it has developed the Yamaha YAS529 Three-Axis Geomagnetic Sensor IC Chip, the world's smallest class of three-axis geomagnetic
sensor for applications related to mobile phones and compact navigation systems. Plans call for beginning to market the chip in October 2006.
Yamaha will soon begin shipping samples of its newly developed YAS529 three-axis geomagnetic sensor, the 2mm x 2mm x 1mm dimensions of which place it in the world's most
compact class of such sensor developed to
date. It is expected to be in strong demand for applications related to mobile phones and compact navigation systems.
Most mobile phones with
GPS functions show the user's current location on a map, but the services are difficult to use because the maps provided do not rotate in response to the user's movements nor do they indicate the direction in which the users is moving. End users have thus been expressing a growing desire for a geomagnetic sensor with an electronic compass function, or "heading up function," that keeps the map oriented in the direction of the user's movement. Moreover, the increasing compactness and thinness of mobile phones seen in recent years is leading to strong demand for ever more compact components of all types.
Since 2005, Yamaha has been mass producing and shipping such products as the YAS525 two-axis geomagnetic sensor and the YAS526 three-axis geomagnetic sensor, both of which are suitable for mobile phones and similar applications. The newly developed YAS529 three-axis geomagnetic sensor features the performance characteristics of the YAS526 sensor but employs newly developed processing technologies to increase compactness. In addition, because some mobile phones are incorporating acceleration sensors to realize new kinds of
game interface applications, the YAS529 features an interface for connections with acceleration sensors. It is thus designed in response to growth in demand associated with GPS and new game interface applications.
The YAS529 combines a buffer amp, an A/D converter, a
clock generator, and a serial interface circuit (I2c bus compatible) on a single three-axis geomagnetic sensor IC chip. When used with portable GPS systems and mobile phones, the YAS529 chip offers high-sensitivity, low-power, and compact electronic compass functions.
