Epson Introduces New Series of Digital-Output Gyroscopic Sensors for Car Navigation Applications

  Epson Introduces New Series of Digital-Output Gyroscopic Sensors for Car
  Navigation Applications

Business Wire

SAN JOSE, Calif. -- November 6, 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 I^2C ^ digital interface.

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 I^2C 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 (I^2C
interface) have a package tilt angle of 0 degrees. The XV4001KD (SPI
interface) and XV4001KC (I^2C 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.”
