X1288V14T1

Overview

The X1288V14T1 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 supports HH:MM:SS:hh time format (12/24 hr) and YY-MM-DD-dd date format. It operates with a supply voltage of 2.7V to 5.5V and a battery voltage of 1.8V to 5.5V. Maximum timekeeping current is 10µA to 20µA at 2.7V to 5V. The component is housed in a 14-TSSOP package (0.173", 4.40mm Width) for surface mount mounting.

Feature Summary

• Integrated Alarm, Leap Year, Supervisor, and Watchdog Timer features
• I2C, 2-Wire Serial interface for communication
• Surface Mount 14-TSSOP package

Applications

• Clock/Calendar systems requiring I2C connectivity

Procurement Notes

Verify the exact suffix 'T1' against official Renesas documentation, as public records predominantly list 'AT1' or 'Z' variants. Confirm RoHS compliance status, as related X1288 models have been documented as non-compliant in some sources. Check part status, as similar X1288 variants are marked obsolete. Ensure the specific tape and reel packaging matches project requirements.

Selection Notes

Select this component if an I2C RTC with supervisor and watchdog timer capabilities is required. Verify that the 14-TSSOP package fits the PCB layout constraints. Ensure the operating temperature range meets the application's environmental needs, noting variations across the X1288 family.

Part Context

This part belongs to the X1288 base product line from Renesas Electronics Corporation. It is categorized under Integrated Circuits (ICs), specifically Clock/Timing Real Time Clocks. The device is designed for applications needing precise timekeeping with additional system management features like alarms and watchdog timers.

Replacement Considerations

Public data confirms X1288V14I-2.7AT1 and X1288V14Z as related variants within the same family. Verify pinout and electrical specifications compatibility before substitution.
