In terms of device manufacturers, the device is used for firmware updates to consumer and industrial devices. Consumer products that are powered by the device include home entertainment systems, digital still cameras and electronic toys. Additionally, it finds practical use in the industrial sector and features in a number of computer based applications. Furthermore, the AT25128N1-10SI-1.8 is a suitable component for use in the telecom sector and can be found in many telecommunications and networking products. Lastly, automobile manufacturers also use the device in applications that involve tracking vehicle performance and providing automated vehicle diagnosis.

Working Principle

The AT25128N1-10SI-1.8 is used by device manufacturers as an inexpensive nonvolatile memory solution. This is because it has a simple serial interface. It also provides a serial number that identifies the device, a unique function which helps to prevent counterfeiting. In addition to this, a security lock is used to guard against unauthorised access attempts – making it an attractive component for manufacturers. The device also allows for over-the-air updates, meaning that manufacturers can update the device firmware without taking apart the device.

The device works by using a 3-wire serial interface with the memory being connected to the system’s microcontroller. A command is first issued from the microcontroller to the AT25128N1-10SI-1.8 which is then acknowledged by the unit. Depending on the command, data is either written to or read from the device. This data is then stored in the AT25128N1-10SI-1.8’s nonvolatile memory. This memory will remain even when power is removed.

The AT25128N1-10SI-1.8 also includes an 8-bit address in its serial instruction set, making it easier to store more than 256 bytes of data. Data can be written onto the chip at a maximum frequency of 400 KHz, while larger data blocks can be written at up to 40 KHz. This makes it suitable for a variety of applications, ranging from consumer products to industrial computers.

In conclusion, the AT25128N1-10SI-1.8 is an ideal component for integrating into devices and systems across a range of industries, due to its versatile nature. Its 3-wire serial interface and 8-bit address instruction set also makes it relatively easy to interface with other components. Consequently, it is an extremely popular memory solution amongst device manufacturers.
