AT49BV002-90JC is a type of specialized NAND Flash memory. It belongs to the class of memory devices known as non-volatile memory (NVM). NVM is a type of computer memory that does not require power to maintain its stored data, whereas volatile memory, such as RAM, does require power to maintain its data. Non-volatile memory is used in numerous applications, including computers, digital television, smartphones, and other electronic devices. It has become an increasingly important component in many of these applications due to its ability to store and recall data regardless of whether it’s powered on or off. The AT49BV002-90JC is a great example of how NAND Flash technology has been used to provide non-volatile memory in applications.

The AT49BV002-90JC is a standard NAND Flash memory device that operates on the 3.3V power supply voltage. It offers a large data storage capacity of up to 2 Gbits, which is split into 64 MByte of data blocks. This capacity is ideal for applications such as industrial controllers, consumer electronics, automotive electronics and embedded systems, as it provides plenty of space for code, data, and storage areas. Furthermore, the device is housed in a standard package of 69-pin TSOP II so that it can be easily mounted onto a PCB board. The device has access speeds of 30 MHz and is capable of providing 200 Mtps (million transfers per second) data transfer rate.

The AT49BV002-90JC can operate in two modes, depending on the function. It can either operate in the regular NOR mode or in Boot Bus Mode. In order to enable Boot Bus Mode, the enable pin (EN) must be set to logic ‘Low’ while a logic ‘High’ is maintained on the address pin (AD). In the NOR mode, the NAND Flash memory is operated as a linear memory and the address is sequentially incremented in the programming instruction, thereby executing an eventual read instruction and resetting the internal read address to the first address of the NAND Flash block.

The AT49BV002-90JC is equipped with a number of features that make it suitable for various kinds of applications. One of these features is the automatic block size check. This feature ensures that the blocks are correctly sized to fit into the internal 512-byte coder. It also prevents errors due to mismatched data sizes. In addition, the chip is designed to be self-programming, which makes it easier to use. The chip is also equipped with an on-chip error-correction code (ECC) algorithm. This feature helps to reduce the impact of soft errors caused by alpha particle strikes, thereby providing more reliable operation.

The AT49BV002-90JC is an excellent choice for applications that require reliable, low-power non-volatile memory. It is designed to provide a simple yet robust solution for data storage, and its advanced features make it suitable for a variety of applications. Although the chip does have some limitations, the combination of features makes it an attractive option for various applications. It is a great example of how NAND Flash technology has been utilized to provide non-volatile memory in a wide range of applications.
