1337AGDVGI8

Overview

The Renesas 1337AGDVGI8 is a low-power serial real-time clock (RTC) IC featuring an I2C interface. It operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperature conditions from -40°C to +85°C. The device counts seconds, minutes, hours, day, date, month, and year with automatic leap-year compensation valid up to the year 2100. It includes two programmable time-of-day alarms and a programmable square-wave output that defaults to 32 kHz upon power-up. The component is housed in an 8-pin MSOP package.

Feature Summary

• I2C Serial Interface supporting Normal and Fast modes
• Automatic date adjustment for months with fewer than 31 days and leap years
• Two programmable time-of-day alarms
• Programmable square-wave output defaulting to 32 kHz

Applications

• Industrial systems requiring precise timekeeping
• Embedded devices needing battery-backed RTC functionality
• Data logging equipment requiring timestamp accuracy

Procurement Notes

Verify moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Confirm RoHS compliance status via official manufacturer documentation before integration. Check current production lifecycle status as availability may vary by region. Ensure I2C bus voltage levels match the 1.8 V to 5.5 V operating range of the device.

Selection Notes

Select this component when a low-power RTC with I2C connectivity is required for space-constrained designs using the MSOP-8 package. Verify that the application environment falls within the specified -40°C to +85°C industrial temperature range. Ensure the system design accommodates the need for external crystal components if not integrated, although this specific variant typically requires external timing elements unless specified otherwise in the detailed datasheet.

Part Context

This part belongs to the 1337AGD series of real-time clocks manufactured by Renesas Electronics. It is categorized under Clock & Timer ICs. The suffix 'DGVI8' indicates the specific package type (MSOP-8), temperature range, and packaging configuration. It serves as a dedicated timing solution for microcontroller-based systems requiring accurate calendar and time tracking.

Replacement Considerations

Consult the official Renesas replacement guide for direct pin-compatible alternatives within the 1337 series. Verify electrical parameter compatibility, specifically supply voltage and I2C speed, when considering cross-model substitutes.
