Description

The DS1307Z+T&R is a low-power, I²C real-time clock (RTC) module from Maxim Integrated (now part of Analog Devices). It provides seconds, minutes, hours, day, date, month, and year data with automatic leap-year compensation (up to 2100).
Key features:
- 56-byte NV RAM for data storage.
- I²C interface (up to 400kHz) for easy microcontroller communication.
- Battery backup support for continuous timekeeping during power loss.
- Low power consumption (under 500nA in battery mode).
- Industrial temperature range (-40°C to +85°C).
The "T&R" suffix indicates it comes in tape-and-reel packaging for automated assembly.
Commonly used in embedded systems, IoT devices, and data loggers for accurate timekeeping. Requires an external 32.768kHz crystal and backup battery for operation.
For more details, refer to the official DS1307 datasheet.

Features

The DS1307Z+T&R is a low-power, I²C real-time clock (RTC) with battery backup. Key features:
- I²C Interface: Simple serial communication (up to 400kHz).
- Timekeeping: Tracks seconds, minutes, hours, day, date, month, and year (with leap-year compensation up to 2100).
- Battery Backup: Operates from a 3V coin cell when main power fails.
- Low Power: Consumes <500nA in battery mode.
- 56-Byte NV RAM: For data storage.
- Programmable Square-Wave Output: Configurable frequencies (1Hz, 4kHz, 8kHz, 32kHz).
- Operating Voltage: 4.5V to 5.5V (main power).
- Industrial Temp Range: -40°C to +85°C.
- Tape & Reel (T&R) Packaging: For automated assembly.
Ideal for embedded systems, IoT, and consumer electronics requiring accurate timekeeping.

Pinout
