Procurement Notes

This component is classified as obsolete and no longer manufactured. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Buyers must confirm the authenticity and condition of existing stock, as standard procurement channels are inactive for this part number.

Selection Notes

Designers should consider the 14-TSSOP package dimensions and the specific I²C interface requirements when integrating this RTC. Ensure that the system power supply aligns with the 2.7V to 5.5V operating range and that battery backup capabilities support the 1.8V minimum requirement for continuous timekeeping during main power loss.

Part Context

The X1228V14IZ-2.7A belongs to the X1228 base product family of real-time clock ICs. It provides non-volatile time and date information with automatic leap year correction. The device includes additional features such as alarms and watchdog timers, making it suitable for applications requiring reliable time management without external microcontroller intervention for basic clock functions.
