X1205S8

Real Time Clock Overview

The X1205S8 is a Real Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation. It provides clock and calendar functions via an I2C, 2-wire serial interface. The device operates within a supply voltage range of 2.7V to 5.5V, with battery backup support from 1.8V to 5.5V. It features alarm capabilities and leap year compensation. The component is housed in an 8-SOIC package with a width of 3.90mm. Operating current ranges from 10µA to 20µA at the specified voltage levels.

Real Time Clock Feature Summary

• I2C, 2-wire serial interface for communication
• Real-time clock/calendar with HH:MM:SS and YY-MM-DD-dd formats
• Alarm functionality and leap year compensation
• Battery backup voltage range of 1.8V to 5.5V

Real Time Clock Applications
