X1227V8

Overview

The X1227V8 is a Real-Time Clock (RTC) manufactured by Renesas Electronics Corporation. It provides timekeeping functions including hours, minutes, seconds, day of the week, date, month, and year with leap-year compensation up to the year 2099. The device communicates via an I²C serial interface and operates within a supply voltage range of 1.8V to 5.5V. It features a watchdog timer and alarm capabilities. The component is housed in an 8-SOIC package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrated Real-Time Clock with calendar functions and leap-year compensation
• I²C serial interface for communication
• Watchdog timer and alarm interrupt outputs
• Wide operating voltage range: 1.8V to 5.5V

Applications

• Data logging systems requiring precise timestamping
• Industrial control equipment needing real-time monitoring
• Consumer electronics with time-display functions

Procurement Notes

Verify the specific suffix 'V8' against official Renesas documentation to confirm package type and temperature grade. Check current product status as RTC components may undergo lifecycle changes. Ensure I²C address compatibility with the host microcontroller before procurement.

Selection Notes

Select this component when a dedicated RTC with I²C interface is required for low-power timekeeping. Verify that the system voltage falls within the 1.8V-5.5V range. Consider the 8-SOIC package constraints for PCB layout. Confirm if the integrated watchdog timer meets the safety requirements of the application.

Part Context

The X1227 series is part of Renesas's portfolio of real-time clock devices designed for general-purpose timekeeping applications. These devices typically replace battery-backed RAM solutions in microcontroller systems to maintain accurate time during power loss.
