GT34C04-2UDLI-TR

Memory IC Overview

The GT34C04-2UDLI-TR is a 4K-bit (512 x 8) non-volatile EEPROM manufactured by Giantec Semiconductor. It operates on a supply voltage range of 1.7V to 5.5V and supports I2C/SMBus interfaces with a clock frequency up to 1MHz. The device features a write cycle time of 5ms for word or page operations. It is housed in an UDFN8 package and functions within an operating temperature range of -40°C to 85°C (TA).

Memory IC Feature Summary

• Supports I2C and SMBus serial communication protocols.
• Designed specifically for Serial Presence Detect (SPD) applications in memory modules.
• Operates across a wide voltage range from 1.7V to 5.5V.

Memory IC Applications

• Serial Presence Detect (SPD) for DRAM modules.
• Memory module identification and configuration storage.
• Embedded systems requiring small non-volatile data storage.

Memory IC Procurement Notes

Verify the exact suffix '2UDLI-TR' against the manufacturer's current datasheet to confirm package type (UDFN8) and tape-and-reel quantity specifications. Ensure compatibility with system voltage levels between 1.7V and 5.5V. Confirm that the I2C address matches your design requirements, as SPD devices often have fixed addresses.

Memory IC Selection Notes

Select this component when designing DDR/DDR2/DDR3 memory modules requiring standard SPD functionality. It is suitable for applications needing reliable non-volatile storage for timing and configuration data. Consider the UDFN8 package size constraints and the requirement for I2C interface support in the host controller.

Memory IC Part Context

This part belongs to Giantec's E²ser series of EEPROMs, which are optimized for memory module applications. It complements other variants like the GT24C64E series but offers lower capacity (4K-bit) tailored specifically for SPD roles rather than general-purpose data logging.

Memory IC Replacement Considerations

Check for direct substitutes such as the GT24C04 series if pinout and electrical characteristics align. Verify that any replacement maintains the same UDFN8 footprint and I2C protocol compliance for seamless integration into existing memory module designs.
