Overview

The AB-RTC-TNA-32.768KHZ-2-T1 is an ultra-low power Real-Time Clock (RTC) module featuring an integrated 32.768 kHz crystal and factory-calibrated temperature compensation. Operating with a typical current consumption of only 240nA at 3V, it provides full clock and calendar functions with an I2C interface and AEC-Q200 qualification for high reliability.

Why Choose This Part

This RTC eliminates the need for external tuning capacitors or crystals by integrating the resonator into a single 8-pin package. Its wide operating voltage of 1.5V to 5.5V and internal Power-On Reset (POR) ensure robust operation across varying power states and battery chemistries.

Applications

Battery-Powered IoT Sensors
Provides accurate timekeeping and wake-up interrupts while drawing minimal current to extend battery life.
Industrial Data Logging
Uses the external event input with timestamping to record precise occurrence times of system events or sensor triggers.
Automotive Subsystems
Leverages AEC-Q200 qualification for reliable timekeeping in vehicle comfort and telematics modules.
Wearable Electronics
The compact 3.2x1.5mm WCDFN package and low power profile suit space-constrained, energy-sensitive portable devices.

Getting Started

Interface the module via its I2C bus using a standard pull-up resistor on the SDA and SCL lines. Engineers should configure the internal control registers to enable alarm interrupts or the square wave output (32.768 kHz, 1.024 Hz, or 1 Hz) for system synchronization.
