DS1371U+C01

Real Time Clock Overview

The DS1371U+C01 is a real-time clock (RTC) IC manufactured by Analog Devices Inc./Maxim Integrated. It features a 32-bit binary counter for elapsed time measurement and a secondary 24-bit counter configurable as an alarm or watchdog timer. The device communicates via an I²C serial interface and operates within a supply voltage range of 1.7V to 5.5V. It supports standard and fast mode I²C protocols, functions in temperatures from -40°C to +85°C, and is housed in an 8-pin μSOP package.

Real Time Clock Feature Summary

• 32-bit binary counter for continuous timekeeping
• Configurable 24-bit counter for alarms or watchdog timers
• I²C bidirectional serial interface supporting standard and fast modes
• Low-voltage operation with data retention current of 100nA

Real Time Clock Applications

• Servers
• Point-of-Sale Equipment
• Portable Instruments
• Elapsed Time Measurements

Real Time Clock Procurement Notes

Verify the C01 suffix against official documentation to confirm specific marking or revision details. Confirm availability through authorized distributors as stock levels fluctuate. Ensure compliance with RoHS standards indicated by the '+' designation. Check for lead-free packaging requirements if applicable to the assembly process.

Real Time Clock Selection Notes

Select this component when a low-power RTC with a 32-bit binary counter is required. Ensure the system supports I²C communication at standard or fast mode speeds. Verify that the operating voltage range of 1.7V to 5.5V matches the system power supply. Consider the 8-pin μSOP package constraints for PCB layout.

Real Time Clock Part Context

The DS1371U+ is part of the Maxim Integrated DS1371 series of real-time clocks. The '+' suffix indicates a lead-free and RoHS-compliant package. The 'U' denotes the 8-pin μSOP package type. This series is designed for applications requiring accurate timekeeping with minimal external components.

Real Time Clock Replacement Considerations

Direct replacements include other parts from the DS1371 family with compatible packages and interfaces. Verify pinout compatibility and register mapping before substitution. Consult the manufacturer's documentation for any obsolescence notices or recommended upgrades.
