1337DVGI8

Overview

The Renesas 1337DVGI8 is a low-power serial real-time clock (RTC) device featuring an I2C serial interface. It counts seconds, minutes, hours, day, date, month, and year with automatic leap-year compensation valid up to the year 2100. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports both Normal Mode (100 kHz) and Fast Mode (400 kHz) I2C communication protocols. It is packaged in an 8-pin MSOP format, suitable for surface-mount applications requiring compact timing solutions.

Feature Summary

I2C Serial Interface supporting Normal and Fast modes
Automatic leap-year correction valid through 2100
Two programmable time-of-day alarms
Programmable square-wave output defaulting to 32 kHz

Applications

Portable battery-powered devices
Industrial control systems
Consumer electronics with time-stamping requirements

Procurement Notes

Verify the specific suffix 'DVGI8' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with system I2C pull-up resistor values and voltage levels between 1.8 V and 5.5 V. Check for moisture sensitivity level (MSL) handling requirements during assembly.

Selection Notes

Select this component when a low-cost, low-power RTC with I2C interface is required. It is functionally equivalent to Maxim DS1337 devices. Consider the 8-pin MSOP package constraints and verify that the external 32.768 kHz crystal load capacitance matches the device specifications for accurate timekeeping.

Part Context

The 1337DVGI8 belongs to the 1337G series of real-time clocks manufactured by Renesas Electronics. This series is designed for applications needing precise timekeeping with minimal power consumption. The device integrates calendar functions and alarm capabilities into a small footprint, making it suitable for space-constrained designs.

Replacement Considerations

The ISL12057 is pin-compatible and functionally equivalent to the Maxim DS1337, which shares core functionality with the 1337G series. Verify register mapping and interrupt polarity before substitution.
