The GT25C32A-2ZLI-TR is a 32Kb (4K x 8) CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Giantec. It utilizes the Serial Peripheral Interface (SPI) for communication and provides non-volatile storage for various embedded systems and applications. This memory device is commonly used to store configuration data, calibration parameters, and other critical information that must be retained even when the power is off. Its low pin count and SPI interface simplify integration into microcontroller-based systems.

Applications

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

Features

• 32Kb (4K x 8) EEPROM Memory

• Low Power Consumption
• Hardware Write Protection
• Supports SPI Modes 0 and 3
• Page Write Capability
• High Reliability and Endurance
• Small Package Options (e.g., SOIC, TSSOP)

Benefits

• Non-volatile storage ensures data retention even without power
• SPI interface simplifies connection to microcontrollers and other SPI-compatible devices

• Page write allows for faster data writing

Additional Details

The GT25C32A-2ZLI-TR employs the SPI protocol for data transfer, supporting modes 0 and 3. The device features a hardware write protect pin, enabling the user to prevent unwanted writes to the memory. The page write mode allows a certain number of bytes (e.g. 32 or 64 bytes depending on implementation) to be written simultaneously, thereby increasing the writing speed. It is available in small surface mount packages and is designed for high endurance (typically 1,000,000 write cycles) with a long data retention (typically 100 years). The SPI clock frequency, voltage, and temperature ranges depend on the datasheet for this specific part.
