Real Time Clock datasheet and documents for DS1337S+T&R

DS1337S+T&R

Real Time Clock Overview

The DS1337S+T&R is a low-power I2C serial real-time clock and calendar manufactured by Analog Devices Inc./Maxim Integrated. It provides seconds, minutes, hours, day, date, month, and year information with automatic leap-year compensation valid through 2100. The device operates on an I2C bus interface with supply voltages between 1.8V and 5.5V for full functionality, while maintaining timekeeping down to 1.3V. Key electrical parameters include an active supply current of 150µA maximum, standby current of 1.5µA maximum, and timekeeping current of 600nA maximum at 1.8V. It features two programmable alarms and a square-wave output in an 8-pin SOIC package.

Real Time Clock Feature Summary

I2C Serial Interface: Supports standard (100kHz) and fast mode (400kHz) communication protocols.

Real Time Clock Applications

Handhelds such as GPS units, POS terminals, and MP3 players
Consumer electronics including set-top boxes and digital recording devices
Office equipment like fax machines, printers, and copiers

Real Time Clock Procurement Notes

Verify the specific suffix T&R indicates tape-and-reel packaging when sourcing this component. Confirm that the S designation corresponds to the 8-pin SOIC package variant. Ensure compatibility with lead-free/RoHS-compliant soldering processes as indicated by the + marking. Check for any known errata associated with specific manufacturing revisions before finalizing procurement plans.

Real Time Clock Selection Notes

Select the DS1337S+T&R for applications requiring an 8-pin surface-mount SOIC footprint. This variant is suitable for designs needing external crystal integration rather than the internal oscillator found in the DS1337C model. Ensure the design supports the required pull-up resistors for the open-drain I2C lines and interrupt outputs.

Real Time Clock Part Context

This component belongs to the DS1337 family of real-time clocks from Maxim Integrated, now part of Analog Devices. The 'S' suffix specifically denotes the 8-pin Small Outline (SO) package, distinguishing it from the DIP or µSOP variants within the same functional family.
