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.
