1339-31DVGI8

Overview

The Renesas Electronics 1339-31DVGI8 is a Real-Time Clock (RTC) IC belonging to the 1339 series. It features a serial I2C interface for communication and operates within a voltage range of 1.8V to 5.5V. The device utilizes an external 32kHz crystal oscillator for timekeeping accuracy. It is housed in an 8-pin TSSOP package with dimensions of 3.0 x 3.0 x 0.97 mm and a pitch of 0.65 mm. The component is lead-free, RoHS compliant, and classified as Moisture Sensitivity Level (MSL) 3.

Feature Summary

• Integrated Real-Time Clock functionality with serial I2C interface
• Wide operating supply voltage range from 1.8V to 5.5V
• Compact 8-pin TSSOP surface-mount package
• Supports external 32kHz crystal input

Applications

• Embedded systems requiring precise timekeeping
• PC hardware and peripheral devices
• Industrial control equipment

Procurement Notes

Verify the specific suffix 'DVG' against official Renesas documentation to confirm the exact package type and tape-and-reel specifications. Confirm current production status and availability through authorized distributors, as inventory levels fluctuate. Ensure compliance with RoHS directives and MSL handling requirements during assembly.

Selection Notes

Select this component when a low-pin-count RTC with I2C compatibility is required for space-constrained designs. Verify that the system power rails support the 1.8V to 5.5V operating range. Ensure the design includes provisions for an external 32kHz crystal resonator and appropriate pull-up resistors for the I2C bus lines.

Part Context

This part belongs to the Renesas 1339 series of real-time clocks. It shares functional similarities with other variants in the family but differs in packaging and specific electrical characteristics defined by the DVG suffix. It serves as a timing reference solution for digital systems needing non-volatile time data retention.

Replacement Considerations

Direct replacements include other Renesas 1339 series variants with compatible pinouts and interfaces. Cross-reference with IDT-branded equivalents if applicable, ensuring voltage ranges and package dimensions match the original design constraints.
