The CAT25160VI is a 16Kb Serial SPI EEPROM manufactured by Catalyst Semiconductor (now owned by ON Semiconductor). It is a non-volatile memory device that can be electrically erased and reprogrammed. It utilizes the SPI (Serial Peripheral Interface) for communication, providing a simple and efficient interface to microcontrollers and other digital systems.

Applications:

• Storage of configuration parameters in electronic systems.
• Storing calibration data in sensors and instruments.
• Data logging in industrial and consumer applications.
• Storing serial numbers and identification codes.
• Replacing DIP switches and potentiometers.

Features:

• 16Kb (2048 x 8 bits) memory capacity.
• SPI (Serial Peripheral Interface) for communication.
• Wide operating voltage range: 1.8V to 5.5V.
• Low power consumption.
• Hardware write protection.
• Software write protection.
• Self-timed write cycle.
• High reliability and data retention.
• Small package options (SOIC, TSSOP).

Benefits:

• Easy integration with microcontrollers using SPI.
• Non-volatile storage ensures data retention even when power is off.
• Low power consumption makes it suitable for battery-powered applications.
• Write protection features prevent accidental data loss.
• Small package size saves board space.
• High reliability ensures long-term data storage.

Additional Details:

The CAT25160VI operates over a temperature range of -40°C to +85°C. It supports SPI modes 0 and 3. The write cycle time is typically 5ms. The device offers both hardware and software write protection mechanisms. The hardware write protection is controlled by the WP pin. The software write protection is controlled by status register bits. The SOIC and TSSOP packages are industry-standard surface-mount packages. This EEPROM is commonly used in applications requiring infrequent writes and long-term data storage. The SPI communication requires four pins: Serial Clock (SCK), Master Out Slave In (MOSI), Master In Slave Out (MISO), and Chip Select (/CS).
