W9725G6KB-18 Application Field and Working Principle

Also known as: W9725G6K

W9725G6KB-18 is a high-performance non-volatile memory ROM module, developed and manufactured by Winbond. W9725G6KB-18 is written in the Flash EPROM technology, the power supply is 2.7V to 3.6V, and the access time is 0.175ns. It is designed to provide users high-speed access memory applications. It has been widely adopted in embedded systems, industrial control applications and other fields, and is an important part of the entire system.

Application Field and Features

W9725G6KB-18 is a 64Mbit, high-performance, low power consumption memory module. Its working environment is relatively wide, and it can work under single 3.3V or dual 2.7V/3.0V power supply, very suitable for use in the special environment of embedded systems and industrial control applications. Especially, it can realize a power consumption of less than 0.6mA within the standby state, which makes it an ideal memory module for energy-saving applications. In terms of features, the W9725G6KB-18 supports fast data transmission, can provide 18 access times at most, and can rapidly transfer data up to 205.5MB per second. In addition, W9725G6KB-18 also supports EDO, burst, page mode and other operations to simplify system adjustments and memory commands.

Working Principle

W9725G6KB-18 is a non-volatile memory module. In terms of the working principle, this chip is essentially similar to the internal structure of the standard Flash EPROM. It is composed of many cells, each of which stores 16 bits of data. The core part of the circuit is composed of a static read control circuit, a static write control circuit, a static flash memory module, and a static programming/erasing circuit. The static read control circuit can achieve reading operations on the storage unit, which provides data readout interface. In this way, data can be read from the memory module at any time.

The static write control circuit is responsible for the various write operations. During the write operation, the logic level of the data is changed from low level to high level. When the write address decoding circuit confirms that the write address matches a certain storage unit, it will start the corresponding write operation to write the data into the storage unit. At the same time, the static programming/erasing circuit is responsible for programming, erasing and verifying the memory, which ensures that the data stored in the memory module is correct.

In summary, W9725G6KB-18 is a highly reliable and high-performance DDR SDRAM which is suitable for environment-sensitive systems, such as embedded systems and industrial control applications. It integrates many advanced technologies and can provide low power consumption, high speed data transmission and other operating performance.
