X1288V14I-2.7T1

Overview

The X1288V14I-2.7T1 is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation, designed for precise timekeeping and calendar functions in electronic systems. It features an I2C and 2-Wire Serial interface for communication, operating within a supply voltage range of 2.7V to 5.5V. The device supports both main power and battery backup (1.8V to 5.5V) to maintain data integrity during power loss. Packaged in a 14-TSSOP surface-mount case, it operates reliably across a temperature range of -40°C to 85°C with low current consumption of 10µA to 20µA.

Feature Summary

• Integrated clock/calendar functionality supporting HH:MM:SS:hh and YY-MM-DD-dd formats
• Includes alarm, leap year compensation, supervisor, and watchdog timer capabilities
• Dual power supply support for main operation and battery backup continuity

Applications

• Data logging systems requiring accurate timestamping
• Industrial equipment needing real-time monitoring
• Consumer electronics with calendar-based scheduling

Procurement Notes

Verify component authenticity through authorized distributors as the part status is obsolete. Confirm package integrity and RoHS compliance before integration. Check for available replacement components due to end-of-life status. Ensure supply chain stability for long-term production needs.

Selection Notes

Select this RTC for applications requiring non-volatile timekeeping with minimal external components. Consider the I2C interface compatibility with the host microcontroller. Evaluate power consumption requirements against the specified standby current. Verify thermal performance within the industrial temperature range.

Part Context

This component belongs to the X1288 series of real-time clocks from Renesas. It provides essential timekeeping functions in a compact surface-mount package. The series is designed for cost-effective integration into various digital systems requiring precise date and time tracking without complex external circuitry.

Replacement Considerations

Consult manufacturer documentation for direct pin-compatible substitutes. Verify functional equivalence regarding interface protocols and memory retention. Assess availability of newer generation RTCs with enhanced features or improved supply status.
