AB-RTC-XP-32.768KHZ-2-T1
Overview
The AB-RTC-XP-32.768KHZ-2-T1 is an ultra-small Real-Time Clock module integrating a CMOS oscillator and a 32.768 kHz crystal resonator into a single 2.0 x 1.2 mm package. It features an I2C interface and operates at exceptionally low voltages down to 0.9V, making it ideal for battery-powered systems that require long-term timekeeping with minimal power overhead.
Why Choose This Part
This module eliminates the need for external tuning capacitors by integrating the crystal and oscillator circuitry, which saves board space and improves reliability. Its wide operating voltage range from 0.9V to 5.5V allows for direct operation from a variety of battery chemistries without additional regulation.
Applications
Getting Started
To interface with this RTC, connect the SCL and SDA pins to your microcontroller's I2C bus with appropriate pull-up resistors. Configure the programmable offset register to fine-tune frequency accuracy and utilize the alarm interrupt pins to wake the host MCU from deep sleep modes.
