ON Semiconductor CAT24C04WI-G EEPROM

The CAT24C04WI-G is a high-performance EEPROM (Electrically Erasable Programmable Read-Only Memory) device from ON Semiconductor, designed for a wide range of applications that require data storage that can be electrically erased and reprogrammed. This integrated circuit features a 4-Kb (512 x 8) memory size and is organized as 512 words of 8 bits each, making it suitable for storing configurations, calibration data, and various user-specific data.

One of the key features of the CAT24C04WI-G is its I²C (Inter-Integrated Circuit) serial interface, which allows for easy integration into most microcontroller-based systems. This two-wire serial interface enables simple and efficient data transfer between the EEPROM and the host controller at speeds of up to 400 kHz. The device also supports a write protect pin, which provides hardware protection of the entire memory array, ensuring that data integrity is maintained.

The CAT24C04WI-G operates over a wide voltage range of 2.5V to 5.5V, making it versatile for both 3.3V and 5V systems. This flexibility allows the EEPROM to be used in various applications, including consumer electronics, industrial control systems, medical devices, and automotive electronics. Its low power consumption and small package size contribute to its suitability for portable and space-constrained applications.

ON Semiconductor has equipped the CAT24C04WI-G with a self-timed write cycle, including auto-erase and auto-write cycles, which ensures that the write operation is completed without the need for external timing elements. Additionally, the device includes an internal error correction code (ECC) logic that enhances its reliability by detecting and correcting single-bit errors automatically.

For designers and engineers looking for a robust and reliable non-volatile storage solution, the CAT24C04WI-G offers a combination of features that make it an excellent choice. Its endurance of 1 million write cycles and data retention of 100 years guarantee long-term reliability of stored data, making it a trusted component in any system design.

Overall, the CAT24C04WI-G from ON Semiconductor is a compact, high-quality EEPROM chip that delivers the performance and reliability required for modern electronic applications.
