X1286A8IT1

Overview

The X1286A8IT1 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 operates on a supply voltage of 2.7V to 5.5V and supports battery backup voltages from 1.8V to 5.5V. It features a current consumption of 10µA to 20µA at 2.7V to 5V. The component is housed in an 8-SOIC package with a width of 5.30mm and is designed for surface mount installation.

Feature Summary

I2C, 2-wire serial interface for communication
Built-in alarm function and leap year compensation
Integrated watchdog timer and monitor functions
Supports HH:MM:SS time format and YY-MM-DD date format

Applications

Clock/calendar systems requiring low power consumption
Data logging applications needing precise time stamping
Embedded systems utilizing I2C connectivity

Procurement Notes

The X1286A8IT1 is listed as obsolete or end-of-life by the manufacturer. Verification of availability through authorized distributors is required, as stock levels may be limited. Buyers should confirm the specific tape-and-reel packaging status and ensure compliance with RoHS directives before procurement.

Selection Notes

Select this component when an I2C-based RTC with integrated watchdog and alarm features is required. Ensure the system voltage aligns with the 2.7V to 5.5V operating range. Verify that the 8-SOIC package dimensions fit the PCB layout constraints. Consider the 10µA to 20µa current consumption for battery-powered designs.

Part Context

This part belongs to the X1286 series of real-time clocks from Renesas. It is distinct from microcontrollers like the R5F101LCDFA#X0 or other memory devices such as the X28HC64 EEPROM. The suffix 'IT1' typically denotes the temperature grade and packaging type within the product family.

Replacement Considerations

Due to the obsolete status, direct replacements must be sourced from secondary markets or equivalent parts from other manufacturers offering similar I2C RTC functionality with comparable voltage ranges and package types.
