The GT34C02A-2UDLI-TR is a 2Kbit EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Giantec. It is a non-volatile memory chip, meaning it retains its data even when power is removed. This particular model is available in a variety of packages and temperature ranges, making it suitable for diverse embedded applications. The device operates on a single power supply and communicates using the I2C serial interface, which requires only two signal lines (SDA and SCL) for data transfer and clocking. Its small size and low power consumption make it ideal for battery-powered devices and space-constrained applications.

Applications

• Consumer electronics: used in set-top boxes, DVD players, and other consumer devices to store configuration settings and user preferences.
• Industrial control systems: storing calibration data, sensor readings, and program code.
• Medical devices: storing patient data, device settings, and log files.
• Automotive electronics: storing vehicle configuration data, sensor calibration parameters, and diagnostic information.
• Smart cards: used to store user credentials, financial data, and other sensitive information.

Features

• 2Kbit (256 x 8) EEPROM
• I2C serial interface
• Low voltage operation (typically 1.8V to 5.5V)
• Low power consumption
• Write protect feature to prevent accidental data corruption
• Self-timed write cycle

Additional Details

The GT34C02A-2UDLI-TR operates over a wide temperature range. It supports standard, fast, and high-speed I2C modes. The device also incorporates a write protect feature, which can be enabled to prevent accidental data corruption. Its self-timed write cycle eliminates the need for external timing components, simplifying the design. The I2C address is configurable using device address pins, allowing multiple devices to share the same I2C bus. It is available in industry-standard packages, making it easy to integrate into existing designs. The part number suffix, -TR, typically indicates tape and reel packaging for automated assembly processes.
