X1288V14Z-2.7

Overview

The X1288V14Z-2.7 is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation. It provides clock and calendar functions via an I²C or 2-wire serial interface. The device operates within a supply voltage range of 2.7V to 5.5V, with battery backup support from 1.8V to 5.5V. It features time formats including HH:MM:SS in both 12-hour and 24-hour modes, and date formats as YY-MM-DD-dd. Key functional attributes include alarm capabilities, leap year compensation, supervisor functions, and a watchdog timer. The component is housed in a 14-TSSOP surface-mount package.

Procurement Notes

This component is classified as Obsolete and is no longer in production. Verification of availability should focus on surplus distributors or existing stock rather than direct manufacturer orders. Users must confirm the specific revision and packaging condition when sourcing from secondary markets due to the end-of-life status.

Selection Notes

Select this part only if legacy compatibility with the X1288 base product is required. Verify that the operating temperature range of 0°C to 70°C meets the environmental constraints of the target application. Ensure the system design accommodates the 14-TSSOP package dimensions and utilizes an I²C or 2-wire compatible controller.

Part Context

The X1288V14Z-2.7 belongs to the X1288 family of real-time clock ICs. It is distinct from the X9429 digital potentiometer and X1228 RTC variants. The suffix 'V14Z-2.7' indicates the specific voltage range and package configuration within the broader X1288 product line managed by Renesas.

Replacement Considerations

No verified public substitute part numbers are available in the provided documentation. Due to the obsolete status, alternative solutions require manual evaluation of pin compatibility and feature parity.
