The Catalyst Semiconductor CAT25040VP2E-GT3 is a 4Kb SPI Serial CMOS EEPROM, organized as 512 x 8 bits. This device provides non-volatile memory storage accessed via a Serial Peripheral Interface (SPI). It is designed for applications that require reliable, low-power data storage, such as storing configuration settings, calibration parameters, and user preferences.

Applications

• Industrial control systems
• Consumer electronics
• Medical devices
• Automotive electronics
• Set-top boxes
• Smart cards

Features

• 4Kb (512 x 8) EEPROM
• SPI Serial Interface
• Low-voltage operation
• Low power consumption
• Self-timed write cycle
• Write protect feature
• High reliability and data retention
• Small Package Options (e.g., SOIC, TSSOP)

Benefits

• Simple interface for easy integration with microcontrollers
• Non-volatile storage retains data even when power is off
• Low power consumption suitable for battery-powered applications
• Hardware write protection prevents accidental data corruption
• High reliability ensures long-term data integrity

Additional Details

The CAT25040VP2E-GT3 supports SPI modes 0 and 3 for versatile communication. It incorporates a self-timed write cycle to simplify write operations. Hardware write protection is available to prevent accidental modification of memory contents. Because this part is END-OF-LIFE, sourcing options may be limited.
