Memory is an important component for many digital devices. In recent years, as the applications of digital devices become more wide-spanning and integrated, the components have to have higher integrated capabilities, faster data transmission speeds, and meet more numerous eco-friendly requirements. One component that meets these criteria is the MX25L12839FZNW-08G.

The MX25L12839FZNW-08G is a 3.3V, 128Mb serial NOR Flash memory chip utilizing the SPI interface. The MX25L12839FZNW-08G has 8x2KB + 8x256B sectors, Quad I/O and Dual I/O command set, Read Identifier and Erase Count functions, which are able to be used with a wide range of embedded applications. It has a 256-byte per page structure and memory capacity of 128Mbit. The MX25L12839FZNW-08G also boasts a low voltage operation and data transfer rate of 104MHz. The main application field for the MX25L12839FZNW-08G component is for use in digital electronic products such as cameras, audio/video equipment and gaming console.

In regard to its working principle, the MX25L12839FZNW-08G implements a Serial Peripheral Interface (SPI) to communicate while transferring data to and from. In addition, it also supports commands from Multi-I/O and Dual-I/O. Command inputs may range from 0x00 to 0xff and the device contains a Data Protection bit to prevent accidental memory change.

Upon powering up, the MX25L12839FZNW-08G will revert to the default mode if no commands are inputted after 10 milliseconds. In order for one to access the data stored in the memory chip, the Read Status Register (RSR) command must be issued. This command should be answered with a value between 0xXX and 0xXX. After the command is successfully sent, regular data transmission can occur. To overwrite any contents in the memory chip, it must first be cleared. This is done by sending the Erase command. The chip then sends a confirmation byte to indicate that erasing was successful. Finally, to read the memory chip’s content, the Read Memory command is sent, which causes the chip to output the data.

Although more recently other flash memory components have come on the market, the design of the MX25L12839FZNW-08G is considered one of the most efficient memories available. It is compact, energy efficient, and works well with a wide range of applications. With its impressive capacities and speed, the MX25L12839FZNW-08G can be used in many tech and digital products such as gaming console, camera, audio/video equipment, Bluetooth headsets and more.
