The AT49F002T-12VC is a type of memory, specifically a 4 megabit (512 K x 8-bit) CMOS Flash memory. It is designed and developed with advanced, high-performance CMOS process to achieve high speed operation, high reliability, and low voltage operation. This type of non-volatile memory is ideally suited for applications where low-power consumption, volatile memory backup and high speed operation are required.

Application Field

AT49F002T-12VC is widely used in consumer electronics, industrial equipment, medical devices, automotive applications, gaming and communications technology. It offer advanced features such as low power consumption, high speed operation, and program/erase-cycle endurance, making it suitable for a wide range of applications. It can also be used as a standard, low-cost substitute for applications requiring large bit densities, including the current ASICs, ROMs, and ROM replacements.

Working Principle

The AT49F002T-12VC is a non-volatile memory then operates by storing the data in in blocks of memory cells called flash blocks. There are two basic types of Flash cells: NAND and NOR. Each type of flash cell is composed of two transistors and a single bit of data. Data can be read from the Flash cells by applying the proper voltage to the transistors. In addition, data can be programmed and erased from the Flash cells by programming the transistors with different voltages.

To program the AT49F002T-12VC, the flash blocks must be programmed with a specific voltage. This is accomplished by writing a logic 0 or 1 to the transistors in each flash block. Logic 0 causes the transistor to be programmed to a lower voltage, while a logic 1 is programmed to a higher voltage. Once the data is written, it is locked and the flash blocks can be erased by applying a higher voltage. This erase voltage causes the transistors to be reset to their original state, erasing the data stored in the Flash blocks.

AT49F002T-12VC also offers several advanced features. It has two modes of operation - fast program mode and erase/program mode. Fast program mode allows faster write/erase cycles, while erase/program mode ensures data is fully erased and written before being locked. This type of memory also includes an auto-erase feature, which erases all memory locations when a power failure occurs. Finally, it features on-chip protection for data stored in the Flash blocks, allowing the device to retain data even in the event of power failure.

The AT49F002T-12VC memory is a high-performance, low-voltage, non-volatile memory with countless applications. It provides excellent data storage and fast operational speeds, as well as several advanced features. With its advanced features, low power consumption, and flexible programming techniques, this type of memory offers many advantages for developers and users alike.
