RV-8263-C7, the universal Real-Time Clock (RTC) module with tiny dimensions for wearables and IoT

Grenchen, Switzerland – Small and highly precise are the key characteristics of the new RTC-module RV-8263-C7. Accepting a large supply voltage range and the small current consumption are ideal for wearable and IoT applications. The tiny package of just 3,5 x 1,5 x 0,8 mm hosts the resonator crystal and the RTC-circuit, nor requiring any pairing.


  • Low power consumption: 190 nA @ 3 V
  • Wide operating voltage range: 0.9 V to 5.5 V
  • Operating temperature range: -40 to +85°C.
  • User programmable offset value
  • Oscillator stop detection
  • Provides year, month, date, weekday, hours, minutes and seconds.
  • Timer and Alarm functions
  • Clock output frequencies: 32.768 kHz to 1 Hz.
  • I2C-bus interface: 400 kHz.
  • Automotive qualification: AEC-Q200
  • Ultra-miniature ceramic SMD package: 3,2 x 1,5 x 0,8 mm
