AB1813-T3

Overview

The Abracon AB1813-T3 is a Real-Time Clock (RTC) IC featuring an SPI interface and 64 bytes of general-purpose RAM. It operates within a supply voltage range of 1.7V to 3.6V, with timekeeping current consumption ranging from 0.17µA to 0.22µA at 1.8V to 3V. The device supports HH:MM:SS:hh time format and YY-MM-DD-dd date format. Encased in a 16-VFQFN Exposed Pad package (3x3 mm), it includes features such as alarms, leap year calculation, and a trickle charger for backup power management.

Feature Summary

Integrated SPI serial interface for communication with host controllers
64 bytes of general-purpose RAM for parameter storage
Ultra-low power consumption with RTC current as low as 14 nA in RC mode
Built-in trickle charger for supercapacitor or battery backup

Applications

Smart cards
Wireless sensors and tags
Medical electronics
Utility meters
Data loggers

Procurement Notes

Verify the specific suffix -T3 corresponds to the Tape & Reel packaging option when ordering. Confirm that the selected component matches the required SPI interface variant, as I2C versions exist within the same family. Ensure the host system voltage aligns with the 1.7V to 3.6V operating range.

Selection Notes

Select the AB1813-T3 when SPI connectivity is required alongside 64 bytes of non-volatile RAM. Consider this part for applications needing advanced power management features like system sleep control and external interrupt monitoring. Verify that the 16-VFQFN footprint fits the PCB layout constraints.

Part Context

This component belongs to the AB18XX series of Real-Time Clocks with Power Management. It is software and pin compatible with other members of the AB18XX and AB08XX families, allowing for potential design flexibility across different interface requirements while maintaining the same physical package dimensions.

Replacement Considerations

The AB0813 is a pin-compatible alternative within the same family but utilizes an I2C interface instead of SPI. Direct substitution requires verifying that the host controller supports the I2C protocol if replacing the AB1813-T3 with the AB0813.
