1338A-31DVGI

Overview

The Renesas Electronics Corporation 1338A-31DVGI is a Real-Time Clock (RTC) IC belonging to the 1338 series. It features an I2C, 2-wire serial interface for communication. The device supports clock/calendar functionality with a storage capacity of 56 bytes. It includes non-volatile SRAM and provides a square wave output. The component operates within a supply voltage range of 3.3V to 5.5V and utilizes a battery backup voltage range of 1.3V to 3.7V. It is housed in an 8-TSSOP package with dimensions of 3.0 x 3.0 x 0.97 mm and a pitch of 0.65 mm. The operating temperature range is -40°C to +85°C.

Feature Summary

• Supports leap year compensation and non-volatile SRAM for data retention.

Applications

• General purpose system control applications requiring timekeeping.

Procurement Notes

Verify the specific suffix 'DVGI' against official Renesas documentation to confirm the TSSOP package and industrial temperature grade. Ensure compatibility with I2C bus protocols used in the target design. Check for moisture sensitivity level requirements during assembly. Confirm RoHS compliance status for the specific manufacturing lot.

Selection Notes
