SAN JOSE, CA--November 10, 2013: Epson Electronics America, Inc. (“EEA”) today began shipping samples of its new XV4001 series of high-precision digital-output gyroscopic sensors. These sensors are available with either an SPI or I2C digital interface.

“We are delighted to bring these products to market”

Gyroscopic sensors are used in car navigation systems to improve the accuracy of GPS systems. By precisely sensing changes in vehicle travel direction, the gyroscope improves accuracy, especially for on-ramps and off-ramps. When GPS signals are lost, such as in tunnels or dense urban areas, the gyroscope provides dead reckoning.

Existing high-accuracy gyroscopes provide an analog output and require an external analog-to-digital converter. Epson’s XV4001 is the first high-accuracy gyroscope to provide a digital output.

Epson’s XV4001 series of gyroscopic sensors integrates a small, stable QMEMS gyroscopic sensor and an Epson IC combining an analog front end, an analog-to-digital converter, and a serial digital interface. They can be ordered with either a 3- or 4-wire SPI interface or an I2C interface. These highly accurate products are fully temperature compensated and include a self-test function.

The XV4001 series consists of four models with different interface and package tilt angle combinations. The XV4001BD (SPI interface) and XV4001BC (I2C interface) have a package tilt angle of 0 degrees. The XV4001KD (SPI interface) and XV4001KC (I2C interface) have a package tilt angle of 20 degrees.

“We are delighted to bring these products to market,” said Masayuki Kitamura, chief operating officer of Epson’s Microdevices Operations Division. “As a leader in crystal devices, Epson will continue to provide the kind of compact, accurate, stable products required in electronics and social infrastructure.”
