AT49F002T-12TC Application Field and Working Principle

Memory

The AT49F002T-12TC is a two-megabit TransFlash flash memory device. It features proprietary NAND Flash architecture and the EZ-NAND concept makes it easier for design engineers to use this device. It is designed for portable consumer applications requiring low power consumption and high data storage capacities. In addition to its general purpose memory attributes, it also has enhanced features such as memory protection, security for user data, error correction and wear leveling for durable storage.

One of the key features of this device is the high capacity of 4 Mbits per block. This density allows for the efficient storage of capacity-intensive data such as music, photos, and videos. The device supports up to nine sectors per block and each sector can be used to store up to 256k bits of data. This allows for the storage of up to 2 Megabytes of data per block.

The AT49F002T-12TC has been designed with a static power-down logic control. This logic allows the chip to remain in low power modes during periods when resources are not required. Since the chip has two power supply pins and the on-chip logic can be used to control the power saving modes, the device can be adapted to many application requirements.

The device has a built-in error correction feature, called ECC (Error Correction Code). This feature is beneficial for applications requiring data integrity, such as GPS receivers and other sensitive data storage applications. This feature increases the reliability of stored data, by correcting any errors that occur in the storage medium.

This device also features write protection and security features, which allow the user to protect their valuable data from unauthorized access. The device is also equipped with built-in wear leveling technology, which helps to increase the lifetime of the device. The wear leveling feature helps maintain the longevity of the device by ensuring that any stored data is distributed evenly throughout the device.

The device requires a 5V supply voltage and includes a 4-bit command set for accessing the memory. The device also features an incremental burst read mode for faster page read operations. In the write operation, the device\'s on-chip write accelerator circuitry provides improved write performance and improved data retention characteristics.

In short, the AT49F002T-12TC memory device is a high-density data storage solution ideal for portable consumer applications. It offers high data density, low power consumption, advanced protection and security, and ECC with wear leveling for reliable and durable data storage.
