X1205V8IT1

Overview

The X1205V8IT1 is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation. It provides clock/calendar functionality with an I2C, 2-wire serial interface. The device operates within a supply voltage range of 2.7V to 5.5V and supports battery backup voltages from 1.8V to 5.5V. It features time formats for HH:MM:SS (12/24 hour) and date formats for YY-MM-DD-dd. Key characteristics include alarm capabilities and leap year compensation. The component is housed in an 8-TSSOP package with dimensions of 0.173 inches (4.40mm) width. Maximum current consumption during timing is specified between 10µA and 20µA at 2.7V to 5V.

Feature Summary

I2C, 2-wire serial interface for communication
Real-time clock/calendar with HH:MM:SS and YY-MM-DD-dd formats
Alarm and leap year compensation features
Supply voltage range of 2.7V to 5.5V

Applications

Systems requiring precise timekeeping via I2C interface
Data logging equipment needing calendar functions
Battery-backed real-time clock applications

Procurement Notes

Verify the specific suffix 'T1' against official Renesas documentation to confirm tape-and-reel packaging versus other variants like 'I'. Confirm RoHS compliance status as some sources indicate non-compliance for similar base models. Check part status as discontinued or active through official channels before procurement.

Selection Notes

Select this component when an I2C-connected RTC with leap year support is required. Ensure the system voltage aligns with the 2.7V to 5.5V operating range. Verify that the 8-TSSOP package fits the PCB layout constraints. Consider the 10µA to 20µA current consumption for power budget calculations.

Part Context

The X1205V8IT1 belongs to the X1205 series of real-time clock ICs. This series is designed for low-power timekeeping applications using standard serial interfaces. The 'V8' designation typically refers to the specific package and temperature grade variations within the family.
