W25Q128JVFIQ TR Datasheet/PDFIntroduction
W25Q128JVFIQ TR is a high-speed serial flash memory suitable for low-power applications, such as consumer grade consumer products, industrial control systems and more. It is designed to have high performance, low power consumption, fast read and write speeds and high reliability.
Outstanding Performance
The W25Q128JVFIQ TR operates at 3.2V, at which it offers fast read and write speeds. Furthermore, its fast write time (1ms / 32KB) helps reduce write latency. Moreover, its data retention time of 20 years also makes it very reliable.
Low Power Consumption
The W25Q128JVFIQ TR can operate at 2.7V, which significantly reduces its power consumption. Furthermore, its Sleep mode offers an even lower power consumption, providing a unique feature for the designer.
Applications
The W25Q128JVFIQ TR is used in a wide range of applications, such as consumer grade consumer products and industrial control systems, including point-of-sale systems, medical devices and many more.
Working Principle
The W25Q128JVFIQ TR is an SPI-compatible serial flash memory, which consists of an array of non-volatile flash memory and an on-chip control logic. An SPI bus along with four different types of commands (read, write, erase and deep power-down) allows the host processor to access the memory. The memory can be accessed in bytes, words, double words, pages and blocks, depending on the requirements of the application.
The device also features a write protect pin (WP#), which can be used to protect against write operations. Additionally, the integrated controller allows the device to be used in a ‘software write protection’ mode. In such cases, the write protect pin can be used in combination with a password, thus providing additional security.
Conclusion
The W25Q128JVFIQ TR is a great choice for low power applications. It combines high performance, low power consumption and great reliability, making it ideal for consumer grade consumer products and industrial control systems. The device is easy to use and provides a wide range of features, making it the perfect choice for many applications.
