ON Semiconductor CAT24C21JI EEPROM

The CAT24C21JI is a high-performance, serial electrically erasable programmable read-only memory (EEPROM) device from ON Semiconductor. It is designed to provide a reliable and efficient non-volatile data storage solution for a wide range of applications. The device utilizes the standard I²C bus interface, making it easy to integrate into any system requiring a dependable memory component.

With a storage capacity of 2-Kb, the CAT24C21JI is well-suited for storing configuration settings, calibration data, or small amounts of information that need to be preserved between power cycles. The EEPROM is organized as 256 x 8 bits, which allows for flexible data management and access.

One of the key features of the CAT24C21JI is its low-power consumption, making it an ideal choice for power-sensitive applications. It operates over a wide voltage range of 2.5V to 5.5V, providing compatibility with both 3.3V and 5V systems. This versatility ensures that the EEPROM can be used in various environments, from battery-operated devices to industrial control systems.

The CAT24C21JI offers a robust data retention period, typically maintaining data integrity for over 100 years. Additionally, the device supports a high write endurance, capable of withstanding at least one million write cycles. This level of durability ensures that the EEPROM can reliably store data for the lifetime of most applications.

ON Semiconductor has equipped the CAT24C21JI with a write protect pin, which can be used to prevent inadvertent writes to the memory array. This feature is particularly useful in applications where data integrity is of utmost importance, and accidental modifications must be avoided.

The device is available in a standard 8-pin PDIP package, which is easy to handle and compatible with common PCB layouts. The CAT24C21JI is also characterized for operation over the full industrial temperature range of -40°C to +85°C, ensuring reliable performance even in harsh conditions.

In summary, the ON Semiconductor CAT24C21JI EEPROM offers a reliable, low-power, and versatile memory solution that is well-suited for a variety of applications requiring non-volatile storage. Its robust feature set ensures that it can meet the demands of both simple and complex memory storage needs.
