DS1307Z+T&R/C01

Real Time Clock Overview

The DS1307Z+T&R/C01 is a low-power serial real-time clock (RTC) IC manufactured by Analog Devices Inc./Maxim Integrated. It provides seconds, minutes, hours, day, date, month, and year information with automatic leap-year compensation valid up to the year 2100. The device includes 56 bytes of battery-backed NV SRAM for general-purpose data storage. It interfaces via an I2C bidirectional bus operating at standard mode frequencies up to 100 kHz. The part operates within a supply voltage range of 4.5V to 5.5V on VCC and supports a backup supply (VBAT) between 2.0V and 3.5V. It features an automatic power-fail detection circuit that switches operation to the backup source when main power is lost.

Real Time Clock Feature Summary

• Integrated BCD clock/calendar with automatic month-end adjustments and leap-year correction through 2100.
• 56-byte battery-backed NV SRAM accessible via the I2C interface.
• Built-in power-fail detect and switch circuitry ensures continuous timekeeping during power outages.
• Programmable square-wave output signal available at 1Hz, 4kHz, 8kHz, or 32kHz.

Real Time Clock Applications

• Data logging systems requiring precise timestamping.
• Power management circuits needing backup timekeeping capabilities.
• Embedded microcontroller systems utilizing I2C communication protocols.

Real Time Clock Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status as indicated by the '+' suffix in the ordering information. Ensure proper handling procedures are followed during surface-mount assembly to maintain device reliability.

Real Time Clock Selection Notes

Select this variant for commercial temperature range applications (0°C to +70°C). For industrial temperature requirements (-40°C to +85°C), consider the DS1307ZN+T&R/C01 equivalent. Ensure external pull-up resistors are sized correctly for the I2C bus capacitance limits specified in the datasheet.

Real Time Clock Part Context

This component belongs to the DS1307 family of serial real-time clocks. The 'Z' designation indicates an 8-pin SOIC package, while '+T&R' specifies tape and reel packaging. The '/C01' suffix typically denotes specific manufacturing or compliance codes associated with the production batch.

Real Time Clock Replacement Considerations

The DS1307ZN+T&R serves as the industrial temperature range alternative. Direct pin-compatible replacements should be verified against I2C timing specifications and voltage levels to ensure functional equivalence in existing designs.
