X1205V8IZT1

Real Time Clock Overview

The X1205V8IZT1 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 alarm capabilities and leap year compensation. The component is housed in an 8-TSSOP package with a width of 4.40mm. It is designed for surface mount installation and functions across a temperature range of -40°C to 85°C.

Real Time Clock 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
• 8-TSSOP surface mount package

Real Time Clock Applications

• Systems requiring precise timekeeping via I2C bus
• Data logging equipment needing calendar tracking
• Battery-backed real-time clock applications

Real Time Clock Procurement Notes

Verify the exact suffix 'IZT1' against official Renesas documentation, as standard listings often show 'X1205V8I'. Confirm RoHS compliance status, as some variants are marked non-compliant. Check current product lifecycle status, as this series may be discontinued or subject to PCN changes. Ensure the tape-and-reel packaging matches the 'ZT1' designation if required for automated assembly.

Real Time Clock Selection Notes

Select this component when an I2C-connected RTC with low power consumption (10µA ~ 20µA) is needed. Ensure the system voltage aligns with the 2.7V to 5.5V operating range. Verify that the 8-TSSOP footprint fits the PCB layout constraints. Consider the -40°C to 85°C industrial temperature rating for environmental suitability.

Real Time Clock Part Context

The X1205V8IZT1 belongs to the X1205 family of real-time clock ICs. This family typically includes variants like X1205S8I and X1205V8I, differing primarily in package type (SOIC vs TSSOP) and reel configuration. The 'V' usually denotes the TSSOP package, while 'ZT1' indicates specific tape-and-reel packaging.

Real Time Clock Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided data. Cross-reference with other Renesas I2C RTCs such as the DS1305 or DS1307 series, ensuring pin compatibility and voltage level matching.
