The Catalyst Semiconductor CAT24C64WI-GT2 is a 64Kb Serial EEPROM organized as 8192 x 8 bits. It utilizes the I²C (2-wire) serial interface, providing a simple and efficient method for non-volatile data storage. It is designed for low-power operation and is commonly used for storing configuration parameters, user preferences, and other critical data.

Applications

• Consumer electronics (e.g., TVs, set-top boxes)
• Industrial control systems
• Medical devices
• Automotive electronics
• Security systems
• Network devices

Features

• 64Kb (8192 x 8) EEPROM
• I²C Serial Interface
• Low Voltage Operation
• Low Power Consumption
• Write Protect Feature
• Self-Timed Write Cycle
• High Reliability and Data Retention
• Small Package Options (e.g., SOIC, TSSOP)

Benefits

• Easy to interface with microcontrollers using the I²C protocol
• Non-volatile storage ensures data is retained even when power is off
• Low power consumption makes it suitable for battery-powered devices
• Write protect feature prevents accidental data corruption
• High reliability ensures long-term data integrity

Additional Details

The CAT24C64WI-GT2 supports standard (100 kHz) and fast (400 kHz) I²C bus speeds. It features a self-timed write cycle, which simplifies the write operation. A write protect input pin provides hardware protection against unwanted data changes. The device operates over a wide voltage range, typically from 1.8V to 5.5V. Because this part is END-OF-LIFE, sourcing options may be limited.
