The Epson SG-8101 programmable oscillators, and SG-9101 spread-spectrum programmable oscillators series have an excellent frequency stability and are able to operate in a wide temperature range. They offer a 50% lower current consumption than comparable Epson products, while the SG-8101 also has 66% tighter frequency tolerance.

The M-V340 6-DOF inertial measurement unit (IMU) from Epson has three axes of gyroscopes and accelerometers, plus provides built-in support for two widely-used industrial and aerospace interfaces: SPI and UART protocol. At just 12x10x4mm in size, the M-V340 IMU is the smallest high-performance IMU on the market today. The M-V340 weighs less than 1 gram, and consumes just 16.5 mA of current, and is capable of withstanding high vibration and shock.

A variety of calibration parameters are stored in a memory of the IMU, and are automatically reflected in the measurement data being sent to the application after the power of the IMU is turned on. With a general-purpose SPI/UART supported for host communication, the
M-V340 reduces technical barriers for users to introduce inertial measurement and minimizes design resources to implement inertial movement analysis and control applications.

The RX8130CE and RX8900CE from Epson are the most advanced Real-Time Clocks available today with long battery life, small size, and best in class accuracy. Both modules are offered in a very small package (3.2 x 2.5 x 1.0 mm) with an integrated IC and crystal. By integrating the crystal, these new RTCs save board space, reduce cost, and improve accuracy as well as functional safety.

To protect against power failure, most RTCs use external components, typically a diode, to switch from main to battery power. Beside using board space these external components the voltage drop across the diode reduces battery life. Epson's RX8130CE and RX8900CE include different versions of automatic power switch that requires no external components and maximizes operating life.

The RX8130CE is a cost optimized low power module featuring a power switch function and achieving an accuracy of 5 ± 23 ppm at 25°C. The RX8900CE uses DTCXO (digital temperature-compensated crystal oscillator) technology to achieve ± 5 or ± 3.4 ppm accuracy over the entire -40 to +85°C operating range. The RA8900CE is AEC-Q200 compliant and manufactured on a dedicated automotive assembly line.

Epson introduced a new family of small, accurate, high-frequency differential-output PLL-based crystal oscillators that support frequencies up to 700MHz. In addition to the SG3225, whose tiny 3.2 mm x 2.5 mm footprint will enable electronics manufacturers to significantly reduce the size of assembled circuit boards, the product family also includes the SG5032 and SG7050, which come in popular sizes of 5.0 x 3.2 mm and 7.0 x 5.0 mm, respectively.

In order to meet these market demands, Epson combined its miniature quartz crystals with PLL ICs to develop this family of differential-output PLL-based crystal oscillators.
With a frequency tolerance of +/- 20 x 10-6 and low phase jitter of 270 femtoseconds, these oscillators offer outstanding accuracy and stability and have a wide operating temperature range (-40° to +85176C). The SG3225, SG5032 and SG7050 are available in two popular output types, LV-PECL and LVDS.

The SG-Writer II from Epson is a new programming tool for the popular SG-8000 series. The SG-Writer II immediately prepares crystal oscillators with the required frequency, which significantly helps to shorten product development and evaluation times. Texim Europe offers customers a special programming service for the Epson SG-8000 crystal oscillator series. Programmable crystal oscillators are the solution to lead times associated with nonstandard custom product.

Soon available
Epson is working on the release of a new programmable oscillator series named SG-8101 and a spread spectrum version named SG-9101. This series are expected to come out later this year (2016).
After upgrade our SG-Writer II we are able to program not only the existing SG-8002 and SG-8003 series but as well the upcoming new series of programmable oscillators.

Epson recently introduced the RX6110SA low power real-time clock (RTC) module. With current consumption of just 130nA (typ.), the RX6110SA current consumption level is 35% lower than that of the RX-8571SA, Epson's existing lowest-current RTC product. Compared to microcontroller implementations, this new RTC can operate eight times longer.

The RX6110SA enables the reduction of hazardous substances by allowing electronic device makers to replace batteries with Supercapacitors. With a 0.33F supercapacitor, this RTC module can operate for 16 weeks. The RX6110SA also includes a diode-less power-supply switching circuit which allows it to operate and charge from power supplies ranging from 5V down to as low as 1.1V.

In addition to keeping time, real-time clocks are used to log power-loss events and save system state when power is lost. The RX6110SA offers a rich feature set to support these needs, including a 32.768 kHz output, alarms and timers and RAM. The RX6110SA supports both SPI-bus and I2C-bus interfaces.

Seiko Epson has developed a series of inertial measurement units (IMU) for industrial applications. These IMU series offer outstanding measurement accuracy and stability while being among the smallest and most energy efficient IMUs in its class.

These IMU's include triple gyroscopes and a tri-axis accelerometer, for 3 or 6 degrees of freedom. The gyroscope provides high accuracy and stability, while the accelerometer offers a dynamic range of up to +/- 6G. It offers excellent angular rate measurement performance and stability. These devices are also equipped with industry-standard SPI and UART interfaces and consume 30mA when operating at 3.3V.

Epson's current available IMU, the M-G350, has earned high marks from customers for its small size, light weight, and outstanding accuracy and stability. With the addition of the M-G352 and M-G362 to the product lineup, Epson will be able to support an even broader range of applications.

The M-G352 and M-G362 are equipped with additional new features, including a higher output data rate, an external trigger input, and counter reset function, making it easy to synchronize measurements with other sensors or with a GPS module in a user's system. Epson plans to begin shipping samples of the M-G362 and M-G352 in August and October of 2013, respectively.

Upcoming small IMU series
Seiko Epson recently announced that they successfully developed the world's smallest IMU. The new M-V340 measures 10 x 12 x 4 mm, weighs 1 gram, and consumes just 18 mA of current, typical. Epson will begin shipping samples of the M-V340 in December 2013.
