1338A-31DVGI8

Overview

The Renesas Electronics Corporation 1338A-31DVGI8 is a Real-Time Clock (RTC) integrated circuit belonging to the 1338 series. It functions as a clock/calendar device with battery-backed non-volatile RAM, providing timekeeping capabilities for electronic systems. The component utilizes an I2C serial interface for communication and is housed in an 8-SOIC package.

Feature Summary

• Integrates real-time clock and calendar functionality with binary-coded decimal format
• Includes battery-backed non-volatile static RAM for data retention during power loss
• Supports leap year compensation for accurate long-term date tracking

Applications

• Data logging systems requiring precise timestamping
• Industrial equipment needing reliable time synchronization
• Consumer electronics utilizing battery-powered backup clocks

Procurement Notes

Verify the specific suffix 'DVGI8' against official Renesas documentation to confirm tape-and-reel packaging and moisture sensitivity levels. Ensure compatibility with system voltage requirements and I2C bus specifications before procurement. Confirm RoHS compliance status through current datasheets.

Selection Notes

Select this component when a dedicated RTC with integrated non-volatile memory is required to reduce board space. Consider the 8-SOIC package constraints and operating temperature range relative to the target application environment. Validate I2C address settings if multiple devices share the bus.

Part Context

This part belongs to the Renesas 1338 family of real-time clocks, which are designed for general-purpose applications requiring accurate timekeeping. The 1338 series typically offers low power consumption and robust features like alarm outputs and square wave generation, distinguishing it from standard timer ICs.
