AT49F002T-12JI

Flash memory is a type of non-volatile memory that can be programmed to store data for easy retrieval. AT49F002T-12JI is a Flash memory integrated circuit, which can provide a storage capacity of 2 megabytes. This IC is suitable for a wide range of applications, including data storage and memory mapping.

The AT49F002T-12JI is one of the most commonly used Flash memories in embedded systems, as it is well-suited for high-end embedded computing, network applications, and industrial control applications. This type of memory is highly attractive for embedded system designers, as it is easy to store data and can be easily re-programmed without the need to erase the existing data.

The AT49F002T-12JI uses a serial peripheral interface (SPI) to communicate with external devices, allowing it to connect with a wide range of devices. This straightforward interface makes it easy to program and read from the memory chip. The AT49F002T-12JI also features a two-wire serial interface (TWSI) for self-programming, allowing it to program itself for further memory expansion.

The AT49F002T-12JI is constructed with a number of components, including four 32 kbyte arrays and two 512 byte page buffers. Each array consists of sixteen 1 kbyte blocks, and each page buffer consists of sixteen 8 byte blocks. The components are arranged in two data structures, which contain two arrays and one page buffer each. To write data to the memory, the device controller sends through an 8 bit instruction code, an 8 bit address, and an 8 bit data package.

The AT49F002T-12JI also includes an on-chip error correction code (ECC) engine, which improves the reliability of stored data by detecting and correcting errors. The ECC engine monitors the memory blocks and detects any errors that occur when writing data. The ECC engine is also used during the read process to ensure data integrity.

The AT49F002T-12JI is widely used in applications such as automotive, consumer electronics, industrial control, telecommunications, and medical instruments. This type of memory is ideal for applications that require data storage and memory mapping for large amounts of data. With its easy programming and high reliability, the AT49F002T-12JI is a popular choice for designers and engineers looking for a reliable storage solution.
