DS1375T

Real Time Clock Overview

The DS1375T is a low-power, fully synchronous I2C real-time clock (RTC) manufactured by Analog Devices Inc./Maxim Integrated. It provides year, month, day, date, hours, minutes, and seconds information, accounting for leap years up to the year 2100. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports both 12-hour and 24-hour time formats with an AM/PM indicator. It features a 16-byte general-purpose RAM block accessible via the I2C bus. The component is housed in a compact 6-TDFN package with an exposed pad and functions reliably across an industrial temperature range of -40°C to +85°C.

Real Time Clock Feature Summary

• I2C serial interface supporting standard and fast modes
• Calendar includes leap-year compensation up to 2100
• 16 bytes of battery-backed general-purpose RAM
• Programmable square-wave output pin

Real Time Clock Applications

• Data logging systems requiring precise timestamping
• Portable electronic devices with limited power budgets
• Industrial control equipment needing reliable timekeeping
• Consumer electronics utilizing I2C communication protocols

Real Time Clock Procurement Notes

Verify the specific suffix designation when ordering, as packaging options such as tape-and-reel may differ from tube configurations. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected variant matches the required operating temperature range and voltage specifications for the target application environment.

Real Time Clock Selection Notes

Select the DS1375T when a small form factor is required alongside I2C connectivity. Compare against the DS1307 if additional alarm functionality or different package types are necessary. Ensure the system design accommodates the 1.7 V minimum supply voltage for low-power operation. Verify that the I2C bus speed requirements align with the device's supported data rates.

Real Time Clock Part Context

This component belongs to the Maxim Integrated RTC family, designed for high-accuracy timekeeping in space-constrained applications. It serves as a drop-in replacement for older asynchronous RTCs while offering improved power efficiency and integrated calendar logic. The TDFN-EP-6 package facilitates surface-mount assembly in modern PCB designs.
