X1228V14IZ

Overview

The X1228V14IZ is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation. It provides clock/calendar functionality via an I2C, 2-wire serial interface. The device supports time formats of HH:MM:SS in both 12-hour and 24-hour modes, and date formats of YY-MM-DD-dd. It operates with a supply voltage range of 2.7V to 5.5V and a battery supply range of 1.8V to 5.5V. Maximum timekeeping current consumption is specified as 10µA to 20µA at 2.7V to 5V. The component is housed in a 14-TSSOP package with a width of 4.40mm and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

Integrated alarm function and leap year compensation
Built-in supervisor and watchdog timer features
I2C, 2-wire serial communication interface
Surface mount 14-TSSOP packaging

Applications

Clock/calendar systems requiring I2C connectivity
Industrial equipment with extended temperature requirements
Consumer electronics needing low-power timekeeping

Procurement Notes

The X1228V14IZ is classified as obsolete and no longer manufactured. Verification of availability should focus on surplus or distributor stock rather than direct manufacturer orders. Ensure compliance with RoHS3 specifications if required by the application. Cross-reference part numbers may be necessary for new designs due to the discontinued status.

Selection Notes

Select this component when a 14-TSSOP RTC with I2C interface is required for industrial temperature ranges (-40°C to 85°C). Verify that the system power supply aligns with the 2.7V to 5.5V operating range. Consider the available substitutes, such as the BU9873NUX-TTR from Rohm Semiconductor, if new production volume is needed, as the original part is discontinued.

Part Context

This part belongs to the X1228 base product series from Renesas Electronics. It shares functional similarities with other variants like the X1228S14I, which uses a 14-SOIC package instead of TSSOP. Both variants offer identical electrical characteristics and feature sets but differ in physical footprint and RoHS compliance status.
