1339-2DCGI

Overview

The Renesas 1339-2DCGI is a Real-Time Clock (RTC) IC featuring an I2C serial interface. It provides clock/calendar functionality with time formats of HH:MM:SS (12/24 hour) and date formats of YY-MM-DD-dd. The device operates within a supply voltage range of 2V to 5.5V, consuming a maximum current of 200µA at 3.63V to 5.5V during timekeeping. It supports battery voltages from 1.3V to 3.7V and functions across an operating temperature range of -40°C to +85°C. The component is housed in an 8-SOIC package.

Feature Summary

Integrated I2C, 2-Wire Serial Interface for communication
Includes Alarm, Leap Year, Square Wave Output, and Trickle-Charger features
Operates on core voltages of 2.5V, 3.3V, 5V, or 5.5V
Initial frequency accuracy of ±10 PPM

Applications

Data logging systems requiring precise timestamping
Industrial control equipment needing calendar tracking
Consumer electronics utilizing low-power real-time keeping

Procurement Notes

Verify the specific suffix 'DCGI' against official Renesas documentation to confirm package type and lead-free status. Confirm availability as distribution channels may vary. Check for Product Change Notices (PCN) regarding manufacturing site updates or material changes before procurement.

Selection Notes

Select this component when an I2C-connected RTC with integrated crystal capabilities is required. Ensure the system design accommodates the 8-SOIC footprint. Verify that the application's power budget aligns with the 200µA maximum timekeeping current specification at the target operating voltage.

Part Context

This part belongs to the 1339 series of Real-Time Clocks manufactured by Renesas Electronics. It shares functional similarities with variants like the 1339-2DVGI but differs in packaging and specific ordering suffixes. The series is designed for applications requiring accurate time and date tracking via standard serial interfaces.

Replacement Considerations

Direct replacements include the 1339-2DVGI, which offers identical electrical specifications and pinout compatibility in an 8-TSSOP package. Verify mechanical fitment differences between SOIC and TSSOP packages if substituting.
