The GT25C128A-2ZLI-TR is a 128Kb (16K x 8) CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Giantec. It is designed for applications requiring non-volatile storage with a Serial Peripheral Interface (SPI). This allows for a small number of pins on the host controller while providing significant memory. The GT25C128A-2ZLI-TR is often used for storing configuration data, calibration parameters, firmware updates, and other non-volatile information in embedded systems and consumer electronics.

Applications

• Consumer Electronics (e.g., TVs, Set-Top Boxes, Gaming Consoles)
• Industrial Control Systems
• Networking Equipment
• Automotive Electronics
• Medical Devices

Features

• 128Kb (16K x 8) EEPROM
• Standard SPI Interface
• Low Voltage Operation (Typically 2.7V to 3.6V or 1.8V)
• Low Power Consumption
• Write Protect Feature
• Page Write Mode
• High Reliability and Endurance
• Small Package Size (e.g., SOIC, TSSOP)

Benefits

• Non-volatile storage that retains data even when power is removed
• SPI interface provides a simple and efficient communication method with microcontrollers
• Low power consumption makes it suitable for battery-powered devices
• Write protect feature prevents accidental data corruption
• Page write mode allows for faster write operations

Additional Details

The GT25C128A-2ZLI-TR utilizes the SPI protocol for communication, supporting modes 0 and 3. It offers a page write mode, allowing for up to a certain number of bytes (e.g., 32 bytes, 64 bytes, depending on the specific variant) to be written in a single operation, improving write performance. The device incorporates a write protect feature, controlled by a dedicated pin, to prevent accidental modification of the memory contents. It is available in various small outline packages, such as SOIC and TSSOP, making it suitable for space-constrained applications. The GT25C128A-2ZLI-TR is designed for high endurance, typically rated for 1 million write cycles per byte, and provides long data retention, usually exceeding 100 years.
