The CAT25C128L is a 128-Kb Serial CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) from ON Semiconductor (formerly Catalyst Semiconductor). It features a Serial Peripheral Interface (SPI) and is designed for applications needing non-volatile storage of data.

Applications:

• Consumer Electronics (e.g., Set-top boxes, DVD players)
• Industrial Control Systems
• Medical Devices
• Automotive Electronics
• Data Logging
• Configuration Storage

Features:

• SPI Interface (Serial Peripheral Interface)
• 128-Kb (16384 x 8) Memory Organization
• Low Voltage Operation (typically 1.8V to 5.5V)
• Write Protection Features (Software and Hardware)
• Self-Timed Write Cycle
• High Reliability and Endurance
• Small Package Options (e.g., SOIC, TSSOP)

Benefits:

• Easy Interface with Microcontrollers
• Non-Volatile Data Storage
• Data Protection Against Accidental Writes
• Cost-Effective
• Suitable for Battery-Powered Applications

Additional Details:

The CAT25C128L communicates via the SPI protocol. It provides both software and hardware write protection mechanisms to safeguard against unwanted data modifications. The self-timed write cycle simplifies write operations. A wide range of operating voltage is supported. It is offered in a variety of packages.
