AB0814-T3

Overview

The Abracon AB0814-T3 is a Real Time Clock (RTC) integrated circuit designed for clock and calendar functions. It features an SPI interface and is housed in a 16-VFQFN Exposed Pad package with dimensions of 3x3 mm. The device operates within a supply voltage range of 1.7V to 3.6V, supporting battery backup from 1.5V to 3.6V. Current consumption during timekeeping is specified between 0.17µA and 0.22µA at voltages of 1.8V to 3V. It includes 256 bytes of SRAM and supports date formats of YY-MM-DD-dd and time formats of HH:MM:SS:hh.

Feature Summary

Integrated SPI interface for serial communication
256B SRAM memory capacity
Built-in alarm, leap year correction, trickle charger, and watchdog timer
Low power consumption: 0.17µA ~ 0.22µA @ 1.8V ~ 3V

Applications

Portable electronic devices requiring precise timekeeping
Battery-powered systems utilizing trickle charging capabilities
Industrial equipment needing watchdog timer functionality

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type variations such as Tape & Reel or Cut Tape. Ensure compatibility with system voltage levels ranging from 1.7V to 3.6V. Confirm interface requirements match the SPI protocol supported by this component.

Selection Notes

Select this model when an SPI interface is preferred over I2C for RTC applications. Consider the 16-VFQFN package size for space-constrained designs. Evaluate the 256B SRAM requirement against application data storage needs. Verify operating temperature range suitability for -40°C to 85°C environments.

Part Context

This component belongs to the Abracon Real Time Clock product line. It provides clock/calendar functionality with additional features like alarms and watchdog timers. The device is manufactured by Abracon LLC and utilizes a surface mount mounting type for PCB integration.

Replacement Considerations

Check for pin-compatible alternatives within the same series that offer different interfaces like I2C if SPI is not required. Verify electrical parameters such as voltage ranges and current consumption match system requirements before substitution.
