Founded in 1978 in Grenchen , Switzerland as a producer of watch crystals, MICRO CRYSTAL has become the leading supplier of miniature quartz crystals for virtually every kind of electronic appliances. Today the three plants in Switzerland , Thailand and China with more than 850 employees produce several hundred million crystals per year. MICRO CRYSTAL, ISO 9001 certified since 1998, has the reputation as an extremely flexible and reliable source for quality frequency-control products.The entire production process is completely controlled by MICRO CRYSTAL, from the raw material, the photolithographic batch process to the finished and tested parts in SMD metal- or ceramic-packages.The high-precision photolithographic process enables MICRO CRYSTAL to produce sub-miniature tuning fork and high frequency AT-cut crystals covering a wide range from 10kHz to 250MHz. These products are used in a variety of markets including telecommunications, medical electronics, consumer, automotive, computer and watch industries.

Featured: RV-1805-C3

Data Sheet This RTC IC has been specially designed for ultimate low current consumption of typically 60 nA @ VDD 3.0V for 32.768 kHz XTAL mode. Additionally, there is an RC-Mode consuming only 17nA and an autocalibrated RC-mode consuming 22nA which permits to operate this RTC module several hours at Backup Supply Voltage using low-cost MLCC. The very small SMT ceramic-package combines the 32.768 kHz crystal unit with the CMOS-based oscillator and real-time-clock IC.
