X1286V14

Overview

The X1286V14 is a Real Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation. It provides clock and calendar functionality via an I2C/2-Wire Serial interface. The device operates within a supply voltage range of 2.7V to 5V, with a timekeeping current consumption specified between 10µA and 20µA under these conditions. It is housed in a 14-TSSOP surface-mount package. Key functional features include alarm capabilities, leap year correction, a supervisor function, and a watchdog timer.

Feature Summary

• Includes alarm functionality for event triggering
• Supports automatic leap year correction
• Integrates a supervisor function for system monitoring
• Contains a built-in watchdog timer

Applications

• General purpose real-time clocking systems
• Embedded devices requiring calendar tracking
• Battery-backed timing applications

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status prior to procurement, as documentation indicates potential variations in environmental compliance. Confirm the exact package type and pinout against the official datasheet to ensure compatibility with the target PCB footprint. Cross-reference the manufacturer's latest release notes for any updates regarding the component's availability or recommended design alternatives.

Selection Notes

Select this component when a low-power RTC with I2C connectivity is required for systems operating between 2.7V and 5V. Consider the 14-TSSOP package constraints and the need for internal alarm and watchdog features. Evaluate the timekeeping current specifications against the power budget of the application to ensure efficient battery life if used in portable designs.
