DS1672S-3+T&R

Real Time Clock Overview

The DS1672S-3+T&R is a Real-Time Clock (RTC) IC featuring a 32-bit binary counter and power-monitoring functions. It utilizes an I²C serial interface for data access and includes automatic power-fail detection with a reset output. The device operates on a primary supply voltage of 2.7V to 5.5V, with a typical nominal rating of 3.0V, and supports low-voltage oscillator operation down to 1.3V. It incorporates trickle-charge capability for battery backup and functions within an operating temperature range of -40°C to +85°C.

Real Time Clock Feature Summary

32-bit binary counter accessible via I²C serial interface
Automatic power-fail detect and switch circuitry with RST output
Trickle-charge capability for backup power sources
Low-voltage oscillator operation starting at 1.3V

Real Time Clock Applications

Portable system controllers requiring precise timekeeping
Embedded systems needing non-volatile real-time clock functionality
Battery-powered devices utilizing trickle charging for backup cells

Real Time Clock Procurement Notes

Verify the specific ordering suffix T&R indicates tape and reel packaging for surface-mount assembly. Confirm that the S variant corresponds to the SOIC-8 package type. Ensure compatibility with the required I²C bus speed and check for lead-free/RoHS compliance status indicated by the plus sign in the part number.

Real Time Clock Selection Notes

Select this component when a 32-bit counter is preferred over BCD format for software-based time derivation. Ensure the system design accommodates the 32.768kHz external crystal requirements, specifically the 6pF load capacitance. Verify that the I²C address 1101000 does not conflict with other devices on the bus.

Real Time Clock Part Context

This part belongs to the DS1672 family of RTCs from Analog Devices/Maxim Integrated. The 'S' designation specifies the 8-pin Small Outline (SO) package, while the '-3+' indicates a 3.0V nominal supply voltage and lead-free construction. The 'T&R' suffix denotes the reel packaging format for automated placement.
