U.S.-Based Epson Toyocom Timing Products Division Announces Compact 32.768 kHz Crystal Unit With Wide Operating Temperature Range for Automotive Applications

EL SEGUNDO, CA--(Marketwire - September 30, 2009) - Epson Toyocom Corporation's U.S.-based Timing Products Division today announced the FC-13A, a tuning-fork crystal unit with operation guaranteed up to a temperature of 125°C, for automotive applications. The FC-13A has an output frequency of 32.768 kHz and measures 3.2 x 1.5 mm, with a maximum thickness of 0.9 mm. The frequency tolerance is +/-20 x 10-6, and the operating temperature range is -40 to 125°C.

The new tuning-fork crystal unit will enter volume production in January 2010. Samples are available now for an estimated price of $3.00 each in small quantities.

The core component in sub-clocks and time management functions is a 32.768 kHz crystal unit. Market demand for miniature 32.768 kHz crystal units that are reliable in high-temperature environments has grown with the increase in recent years of feature-rich automotive applications. The spread of hybrid cars and electric vehicles has also fueled the growth of new automotive applications, such as battery monitoring functions. Auto manufacturers further require that components be lead-free for environmental reasons.

Epson Toyocom has addressed these market needs with its QMEMS(*1) technology, which let the company shrink the FC-13A's package to less than one-tenth the volume of its predecessor, the MC-30A. Original packaging technology enables the FC-13A to support an operating temperature range from -40 to 125°C, with automotive-grade levels of performance and reliability. It is also compliant with the AEC-Q200(*2) quality standard for automotive electronics.

In addition, the lead-free FC-13A conforms to EU RoHS Directive and ELV Directive requirements.

Glossary

(*1)QMEMS

QMEMS is a combination of "Quartz," a crystalline material with excellent characteristics such as excellent frequency stability and high precision, and "MEMS" (micro electro mechanical system). QMEMS devices, produced via a microfabrication process on a quartz material instead of on a semiconductor material like MEMS, offer high performance in a compact package.

QMEMS is a registered trademark of Epson Toyocom.

(*2) AEC-Q200

The Automotive Electronics Council (AEC) was established by the "Big Three" automobile manufacturers and American auto parts manufacturers for the purpose of defining common standards for the qualification and reliability of automotive electronic components.

AEC-Q200 is a global standard established by the AEC. It is widely used in Europe and America as a standard for passive electronic components used in the automotive industry.
