The device combines many of the features of other flash memories into a single package, providing users with an economical and efficient data storage solution. The AT49F002T-90JC is ideal for storage of data, images, music and other digital content.

Application Field

The AT49F002T-90JC is most commonly used in consumer devices, such as digital cameras, PDAs, MP3 players and cell phones. With its low power consumption and efficiency, the AT49F002T-90JC is an excellent choice for applications that need to store large amounts of data without consuming a lot of energy. The device is also well suited for updating firmware, as the user can easily upgrade their device without any extra hardware.

Working Principle

The AT49F002T-90JC works by utilizing NAND Flash, which is a type of non-volatile memory. Non-volatile memory means that the data stored on the chip will not be lost when the power is turned off. NAND Flash allows the data to be written, erased and rewritten multiple times with minimal wear and tear.

The AT49F002T-90JC utilizes multiple chips arranged in two banks. Each chip is eight bits wide and can store a total of 16 MB of data. Data is stored in blocks of 64 KB, which are written, erased and rewritten sequentially. The AT49F002T-90JC also incorporates built-in error correction codes in order to ensure data integrity.

The chip also includes a built-in SRAM buffer, which allows the user to store data before it is written to the Flash memory. This feature minimizes energy consumption and increases the speed of data transfers. The AT49F002T-90JC also includes numerous security measures, such as password protection, multi-level access control and encryption algorithms.

Conclusion

The AT49F002T-90JC is a reliable, low-cost, and energy-efficient data storage solution designed to meet the needs of consumer-level applications. With its integrated features and reliable data storage capabilities, the device is an excellent choice for a variety of data storage needs.
