X1288V14I-2.7

Overview

The X1288V14I-2.7 is a Real Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation, belonging to the X1288 base product family. It provides clock and calendar functions via an I2C, 2-Wire Serial interface. The device supports HH:MM:SS:hh time format in both 12-hour and 24-hour modes, alongside YY-MM-DD-dd date formatting. It operates with a supply voltage of 2.7V to 5.5V and a battery voltage range of 1.8V to 5.5V. The maximum current consumption for timekeeping is specified as 10µA to 20µA at 2.7V to 5V. The component is housed in a 14-TSSOP package with a width of 0.173 inches (4.40mm) and is designed for surface mount mounting.

Feature Summary

• Integrated Alarm, Leap Year correction, Supervisor, and Watchdog Timer features
• I2C, 2-Wire Serial communication interface
• Surface Mount 14-TSSOP package (0.173" / 4.40mm width)
• Operating temperature range of -40°C to 85°C

Applications

• Systems requiring precise real-time clock and calendar tracking
• Data logging applications needing low-power timekeeping
• Industrial equipment utilizing supervisor and watchdog timer functions

Procurement Notes

The X1288V14I-2.7 is classified as Obsolete by the manufacturer. Verification of RoHS compliance indicates non-compliance status. Sourcing should prioritize checking for available stock or confirmed replacement components from official distributors, as new production is discontinued.

Selection Notes

Select this component when an I2C-connected RTC with integrated supervisor and watchdog capabilities is required. Ensure the design accommodates the 14-TSSOP package dimensions and the -40°C to 85°C operating temperature range. Verify that the system power supply aligns with the 2.7V to 5.5V main voltage and 1.8V to 5.5V battery voltage specifications.

Part Context

This part is a variant within the X1288 series of real-time clock ICs. The 'V14' suffix typically denotes the 14-TSSOP package option, while 'I' indicates the industrial temperature grade (-40°C to 85°C). The '2.7' specifies the minimum operating voltage threshold. It serves as a legacy component in Renesas's timing portfolio.
