X1286V14T1

Overview

The X1286V14T1 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 is housed in a 14-TSSOP package with dimensions of 0.173 inches (4.40mm) width. It operates within a supply voltage range of 2.7V to 5.5V and supports battery voltages from 1.8V to 5.5V. The maximum current consumption during timing is between 10µA and 20µA at 2.7V to 5V. The operational temperature range is specified from 0°C to 70°C.

Feature Summary

Integrates clock and calendar functions with alarm capabilities
Supports leap year calculation for accurate date tracking
Includes supervisor and watchdog timer features

Applications

Embedded systems requiring precise timekeeping

Consumer electronics with real-time clock requirements

Procurement Notes

Verify component authenticity through authorized channels as the part status may be obsolete. Confirm package type matches design requirements. Check RoHS compliance status prior to integration. Ensure supply voltage ranges align with system power architecture. Validate temperature ratings against environmental conditions.

Selection Notes

Consider interface compatibility when integrating with microcontrollers supporting I2C protocols. Evaluate power consumption constraints relative to battery-operated applications. Assess physical space limitations against the TSSOP package dimensions. Review feature set including alarms and timers against functional needs. Verify operating temperature range suitability for target deployment environments.
