AT26DF161A-SSU

Introduction

The AT26DF161A-SSU is a type of nonvolatile memory device. It is used to store and retrieve data. It is a product of Microchip Technology Inc. The chip stores 16 Mbits (2Mb x 8) of data. It has a 32-bit organization and is a Serial Peripheral Interface (SPI) compatible device. It operates from a single 2.7-3.6V supply and can be used as an external storage device for many different microcontroller applications.

Application Field

The AT26DF161A-SSU is a popular choice for many different embedded applications. In the consumer and industrial sector, it is used for data storage, such as for software, system configurations, and measurement data. In the automotive industry, it is used to store vehicle settings and other valuable data on-board. It is also used in mobile phones and other portable devices, such as digital cameras and PDAs. In addition, the AT26DF161A-SSU is used in medical and healthcare applications, such as medical history storage and vital monitoring.

Working Principle

The AT26DF161A-SSU is a nonvolatile memory device, meaning that the stored data is not lost when power is removed. The device uses Flash memory and EEPROM technology to store and retrieve data. When data is written to the AT26DF161A-SSU, it is written to Flash memory blocks. These blocks are individually erasable and can be written to and erased multiple times, making them ideal for storing frequently changing data. When data is retrieved from the AT26DF161A-SSU, it is read from the EEPROM, which is slower but more reliable than Flash memory. The AT26DF161A-SSU uses a Serial Peripheral Interface (SPI) for communication between the memory device and the microcontroller.

Conclusion

The AT26DF161A-SSU is a type of nonvolatile memory device with a 16Mb (2Mb x 8) capacity. It uses Flash and EEPROM technology to store and retrieve data. Its low power consumption and fast write speed make it ideal for many embedded applications in the consumer and industrial sector, automotive industry, mobile phones, digital cameras, PDAs, and medical and healthcare applications. The AT26DF161A-SSU uses a Serial Peripheral Interface (SPI) for communication between the microcontroller and the memory device.
