The 32.768 kHz quartz crystal and semiconductor RTC chip of the RV-8263-C7 are housed in a 3.5x1.5x0.8mm miniature package and offer a wide input voltage range from 0.9 to 5.5V with a very low current consumption of only 190nA at 3V. In addition, a very high stability of ±20 ppm at 25°C is achieved through individual calibration during production. Due to the perfect coordination of the individual RTC components, a later calibration in the customer's production is no longer necessary. Furthermore, a frequency offset register for individual tuning and both timer and alarm functions as well as pre-programmed 30s and 60s time markers have been integrated.
The combination of extremely small size, wide supply voltage range and low current consumption makes the RTC module RV-3028-C7 flexible and predestined for state-of-the-art wearables and consumption-sensitive IoT applications. The crystal family is also suitable for automotive applications: The components meet the requirements of the AEC-Q200 standard.
The products are available through the distributor WDI AG (Wedel, Germany).
