Abracon Ultra-Low Power RTC Modules
Abracon Ultra-Low Power RTC Modules provide an embedded 32.768kHz crystal oscillator and an I2C communication interface. These Real-Time Clock (RTC) modules offer ±20ppm frequency accuracy at 25°C in a compact and lead-free ceramic SMD 2mm x 1.2mm package. The ultra-low power RTC modules support a broad operating power supply range of 0.9V to 5.5V, with 190nA of low power consumption at 3V. These RTC modules feature a digital offset function, alarm and timer function, oscillator stop detection, and an internal Power‑On Reset (POR) function. The ultra-low power RTC modules are REACH/RoHS II compliant and are rated at MSL level 1. Typical applications include IoT, smart metering, industrial, factory automation, health care monitoring systems, wearables, portables, and sensors.
