W25Q256JVEIQ is a type of serial non-volatile Flash memory released by Winbond. It is widely used in industrial core related fields and is formally called the Serial NAND Flash.

In the memory industry, W25Q256JVEIQ usually uses SPI (Serial Peripheral Interface) as the interface. It adopts an 8-pin WSON-8C or 8-pin UDFN package (can also choose a 8-pin or 16-pin TSOP-Type-I package). It has a capacity of up to 32Mbytes and supports various types of commands. In addition, W25Q256JVEIQ has a maximum clock frequency of 104MHz, which can provide fast read performance.

The W25Q256JVEIQ is divided into two types, one is a standard product, and the other is a high-performance product. The standard products and their respective performance are as follows: highest operating temperature can reach 85℃, write and erase speed of 5Mbit/s and 40Mbit/s respectively, and maximum clock frequency of 104MHz, read speed of 104Mbit/s, write speed of 64Mbit/s; while the high-performance products and their performance are higher to reach 95℃, write and erase speed of 10Mbit/s and 60Mbit/s respectively, maximum clock frequency of 204MHz, read speed of 204Mbit/s, write speed of 104Mbit/s.

Working principle of W25Q256JVEIQ is quite simple. When the power is turned on, a power-on reset (POR) signal is sent to the chip, so that all registers are in the state of reset. Then a Reset completion interrupt is sent to the host, which allows the microcontroller to initialize all necessary registers. After the initialization, data is transferred from memory using the SPI protocol.

W25Q256JVEIQ is receiving increasing attention from the industrial control field. With its high performance, small size, fast read and write speeds, power-on reset signal, high temperature degrees, and low power consumption, W25Q256JVEIQ has become the preferred type of Serial NAND Flash by more and more users. It can be widely applied in some industrial applications such as system controllers, industrial process controllers, remote data acquisition systems, portable instrumentation and embedded modules.

In summary, W25Q256JVEIQ is one of the best Serial NAND Flashes in the memory industry. It has a variety of features, such as excellent electrical properties, wide operating temperature range and low power consumption, making it the first choice of embedded industrial control applications.
