Active14,884 in stock
Overview
The CAT25040VI-GT3 is a 4Kbit CMOS Serial EEPROM organized internally as 512 words of 8 bits each. It utilizes the Serial Peripheral Interface (SPI) protocol and is designed to handle high-reliability data storage with a 1.8V to 5.5V supply range.
Why Choose This Part
This device features a 16-byte page write buffer and a high-endurance rating of 1,000,000 program/erase cycles. It offers robust data protection through both software and hardware block write protection, alongside a 100-year data retention rating.
Applications
Configuration Storage
Ideal for storing calibration data, device settings, and user preferences in embedded systems.
Parameter Logging
Records operational parameters and error logs in industrial equipment requiring non-volatile memory.
Identification Data
Storing serial numbers, MAC addresses, and revision codes for hardware identification.
