1338B-18DVGI8

Overview

The 1338B-18DVGI8 is a Real Time Clock (RTC) integrated circuit manufactured by Renesas Electronics. It belongs to the 1338 series and is designed for precise timekeeping applications. The component operates within a standard voltage range suitable for various digital systems. It features an I2C serial interface for communication with host microcontrollers, allowing for easy integration into embedded designs. The device includes battery backup capabilities to maintain timekeeping during main power loss. It is supplied in a Reel packaging format with a factory quantity of 2500 units.

Feature Summary

• Integrated Real Time Clock functionality with calendar and alarm features
• I2C Serial Interface for low-pin-count connection to host processors
• Battery Backup Input for continuous operation during power outages
• RoHS Compliant and Moisture Sensitive Level 1 rated

Applications

• Embedded systems requiring accurate time stamping
• Industrial control panels needing persistent timekeeping
• Consumer electronics with clock display functions
• Data logging devices requiring timestamp accuracy

Procurement Notes

Verify the specific suffix 'DVGI8' against the official Renesas datasheet to confirm package type and tape/reel specifications. Ensure compatibility with I2C bus voltage levels before integration. Check current availability status as distribution may vary by region. Confirm RoHS compliance documentation is available for regulatory requirements.

Selection Notes

Select this component when a dedicated RTC with I2C interface is required. Compare pinout and voltage specifications with existing system constraints. Consider the 1338 series family for potential future upgrades or replacements. Verify temperature range suitability for the intended operating environment.

Part Context

This part is part of Renesas' 1338 series of real-time clocks. It shares functional similarities with other models in the series but differs in specific package and ordering suffixes. It serves as a standalone timekeeping solution for systems that do not have an internal RTC in their main processor.

Replacement Considerations

Consult the Renesas product transition notices for any end-of-life announcements. Direct substitutes within the 1338 series should be verified for pin-to-pin compatibility and electrical parameter equivalence.
