概要

Description

The DS1307Z+ is a real-time clock (RTC) IC manufactured by Maxim Integrated. It provides a low-power, full binary-coded decimal (BCD) clock/calendar with 56 bytes of non-volatile SRAM. The device keeps track of seconds, minutes, hours, day, date, month, and year, including leap-year compensation up to 2100.
Operating on a 5V supply, the DS1307Z+ communicates via an I2C interface, making it easy to integrate with microcontrollers. A key feature is its ability to continue timekeeping in the event of a power failure, powered by an external battery.
The clock operates in either 24-hour or 12-hour format with AM/PM indicator. The DS1307Z+ package is compact, suitable for space-constrained applications. It is commonly used in embedded systems, data loggers, and other applications requiring precise timekeeping with minimal power consumption.
Overall, the DS1307Z+ is valued for its reliability, simplicity, and ease of use in various electronic projects.
