X1288V14Z-2.7A

Overview

The X1288V14Z-2.7A is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation, belonging to the X1288 base product family. It provides clock/calendar functionality with HH:MM:SS time format and YY-MM-DD-dd date format. The device supports I²C and 2-wire serial interfaces for communication. Key features include an alarm function, leap year compensation, a supervisor, and a watchdog timer. It operates within a supply voltage range of 2.7V to 5.5V, with battery backup support from 1.8V to 5.5V. Timekeeping current consumption is specified as 10µA to 20µA at 2.7V to 5V. The component is housed in a 14-TSSOP package (0.173", 4.40mm width) and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrated Real-Time Clock with Calendar functionality supporting 12/24 hour formats
• I²C and 2-Wire Serial interface compatibility
• Built-in Alarm, Leap Year compensation, Supervisor, and Watchdog Timer
• Low power consumption: 10µA ~ 20µA during timekeeping

Applications

• Data logging systems requiring precise timestamping
• Consumer electronics needing calendar and alarm functions
• Industrial control systems utilizing watchdog supervision
• Battery-powered devices leveraging low standby current

Procurement Notes

The X1288V14Z-2.7A is listed as Obsolete or End-of-Life (EOL). Verification of availability should be conducted through authorized distributors or secondary market suppliers. Check for RoHS compliance status, as some listings indicate compliance while others may vary based on production batch. Confirm package integrity and moisture sensitivity level (MSL 1) prior to procurement.

Selection Notes

Select this component when I²C or 2-wire serial RTC functionality is required in a 14-TSSOP package. Ensure the application environment stays within the 0°C to 70°C operating temperature range. Verify that the system voltage aligns with the 2.7V to 5.5V supply requirement. Consider the X1228 series if a wider industrial temperature range (-40°C to 85°C) is needed, as it shares similar functional features.

Part Context

This part belongs to the X1288 series of Real-Time Clock ICs from Renesas. It is functionally related to the X1228 series, which offers extended temperature ratings. Both series share common interface protocols and feature sets like alarms and watchdog timers, differing primarily in packaging options and thermal specifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult Renesas official documentation for cross-reference recommendations or evaluate the X1228 series for alternative sourcing.
