N25Q128A13E1440E, a member of the family of SPI NOR flash memory devices, is a type of non-volatile memory that provides fast read and write access to stored data. It is commonly used in applications requiring high-density storage and reliability, with an industry leading 128 Mb capacity stored on a single chip. In addition to its ample storage capacity, N25Q128A13E1440E also offers good read performance (up to 133 MHz clock speeds) and write performance (up to 33 MHz). It also provides a low power consumption (down to 1.5 mW in Run mode, and 0.5 mW in Standby).

N25Q128A13E1440E’s main application fields are consumer electronics and automotive products. Consumer electronics such as mobile phones, TVs, and other home appliances can use the high-density storage capabilities of this device to handle large amounts of data quickly with minimal power consumption. For automotive products, its low power consumption allows the device to be used in embedded systems that are always on, such as those for on-board diagnostics, or low-power infotainment systems. It is also suitable for applications such as medical imaging, industrial automation, and defence sectors.

The working principle of N25Q128A13E1440E lies in its simple and efficient memory management scheme. It stores data in contiguous memory blocks called “spi_assert”, which are organized in pages of 128 bytes. It also has a “reset pin”, which can be used to reset the SPI interface and execute a full reset operation. Furthermore, it has two types of addressable memory regions: code memory (which stores instructions) and data memory (which is used to hold static and dynamic data). The memory access is controlled by a set of commands that are issued by the host device. These commands include commands for reading, writing, erasing, programming, and verifying data.

The working principle of N25Q128A13E1440E includes a set of protections to ensure data integrity. These include an advanced write protection scheme that ensures that the data stored in the write buffer can never be erased. In addition, N25Q128A13E1440E has an extended erase protection which locks the stored data from accidental erasure. Finally, the device includes a power-on reset functionality to ensure that all the data stored in the memory is consistently retained when power is restored.

To sum up, N25Q128A13E1440E is a type of non-volatile memory that is suitable for a variety of applications requiring high storage capacity, good read and write performance, and low power consumption. Its main application fields are consumer electronics and automotive products, and its working principle entails a simple, efficient memory management scheme with various protections to ensure data integrity. It is a reliable and robust memory solution, making it the perfect choice for a variety of applications.
