AT45DB161B-TI is a type of non-volatile memory. It is organized into 16,777,216 pages of 528 bytes in-system programmable Flash memory, two times the density of current 256-megabit solutions. Memory space is evenly distributed between two separate sections, providing a total of 8 megabits of space for data, with each section delivering 4 megabits. A single sector can be easily erased, lessening programming time. In addition, AT45DB161B-TI features a very low quiescent power consumption—85 µA when idle—making it ideal for use in battery-powered applications.

AT45DB161B-TI is optimized for use in embedded systems and in applications where non-volatile code storage, data logging, and parameter storage are needed. It is very useful in applications such as industrial, automotive, medical and military fields, owing to its endurance capacity, write speed and data retention. In addition, the lack of need for additional external components makes it particularly suitable for embedded systems.

The working principle of AT45DB161B-TI is based upon a continuous array of memory cells that are interconnected in a grid pattern. These cells are arranged in two separate sections, which each section providing 4 megabits of space for data. Data is read from the device, erased and then written back to the device. It is governed by various commands, such as Read, Program, Erase, etc. Each command is issued to the device over a two-wire interface. The device then identifies the command through a unique op code and then executes it.

AT45DB161B-TI has higher write speed as compared to other types of Flash memory. This is because the device relies on a page programming operation, allowing multiple bytes to be programmed simultaneously. Furthermore, it features an enhanced weak bit detection mechanism that reduces programming time while still maintaining data integrity. This makes it ideal for applications where fast write speed is of paramount importance.

AT45DB161B-TI also features an in-system programmable (ISP) function which allows the user to customize their device’s configuration. This feature allows the user to set their own configuration parameters, allowing them to tailor their device to suit their specific application’s needs. Furthermore, AT45DB161B-TI also offers a data protection mode that can be used to secure data from unauthorised access.

In conclusion, AT45DB161B-TI is an ideal solution for a wide range of applications requiring non-volatile memory. Its wide range of features, such as its high write speed, data protection mode and the ability to customize its configuration, make it ideal for use in embedded systems and for applications where data logging, parameter storage and non-volatile code storage are necessary. Furthermore, its low quiescent power consumption makes it suitable for use in battery-powered applications.
