Description
The CAT24C32WI-GT3 is a 32Kb I2C CMOS Serial EEPROM device designed for high-reliability data storage applications. It operates using the I2C protocol, allowing communication speeds of up to 1 MHz. The EEPROM is organized in 4096 bytes, making it suitable for various applications requiring non-volatile memory. It supports a wide voltage range (1.7V to 5.5V), ensuring compatibility with numerous electronic systems.
This device features a Schmitt Trigger, filtering for noise suppression, and a power-on-reset circuit, ensuring reliable operation under varying conditions. It also has write-protection capabilities, including a write-protect pin, to prevent accidental data overwrites. The CAT24C32WI-GT3 is commonly used in consumer electronics, automotive, industrial, and communication equipment due to its robust data retention (up to 100 years) and a high endurance cycle of 1,000,000 write/erase cycles.
Packaged in an 8-pin SOIC, the CAT24C32WI-GT3 is compact, making it suitable for space-constrained applications. This EEPROM is ideal for applications requiring efficient, reliable, and secure data storage.
