Abracon AB-RTC-XL Low-Power Real-Time Clocks (RTCs)
Abracon AB-RTC-XL Low-Power Real-Time Clocks (RTCs) are ultra-low-power RTC modules with an embedded 32.768kHz crystal oscillator. These devices use an I2C communication interface to configure numerous features while maintaining frequency accuracy (±20ppm at +25°C) in a compact, lead-free ceramic 3.2mm x 1.5mm SMD package.
These features include a digital offset function, alarm and timer function capability, oscillator stop detection, and an internal power-on reset function. The RTC has a broad operating power supply range of 0.9V to 5.5V with low power consumption (190nA at 3V).
The Abracon AB-RTC-XL Low Power RTCs are ideally suited for battery-powered Internet of Things (IoT) devices, wearable and portable electronics, energy-harvesting systems, telematics and infotainment, and smart home devices. Automotive qualification according to AEC-Q200 (AB-RTC-XLA) is also available for high-reliability applications such as advanced driver assistance systems.
