The CAT1163WI-45 is a serial EEPROM manufactured by Catalyst Semiconductor, designed for non-volatile data storage in a variety of electronic applications. The serial interface enables straightforward connection to microcontrollers and other digital circuits, simplifying system design. It is a CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory), meaning data can be electronically erased and reprogrammed.

Applications

• Storage of configuration parameters
• Data logging in embedded systems
• Storage of serial numbers and identification codes
• Calibration settings storage

Features

• 4Kbit (512 x 8) EEPROM
• Low voltage operation
• Serial interface (I2C or SPI, depending on specific variant)
• Write protect feature for data security
• Low power consumption, ideal for battery-powered devices
• Self-timed write cycle

Benefits

• Non-volatile memory retains data without power
• Low voltage operation prolongs battery life
• Small form factor saves space on PCBs
• Simple serial interface reduces design complexity
• Write protection prevents accidental data loss or corruption

Additional Details

The CAT1163WI-45 is typically used in systems requiring persistent storage of small amounts of data. The serial interface facilitates seamless connection to microcontrollers or other system components. A write protect feature ensures the stored data remains secure from accidental modifications. Organized as 512 bytes x 8 bits.

As an END-OF-LIFE component, verifying the current availability and considering alternatives for newer projects is essential. Its compact size and ease of interfacing made it a popular choice for storing configuration data. Due to its EOL status, it's important to address any obsolescence concerns and plan accordingly.
