AT45DB041D-SSU

Memory is a type of physical device used to store information, either temporarily or permanently. It is generally divided into two main categories, namely volatile and non-volatile memory. Volatile memory includes random access memory, while non-volatile memory includes read-only memory and flash memory. The AT45DB041D-SSU is an example of a non-volatile flash memory.

The AT45DB041D-SSU is a 4-Mbit (512K x 8) low-power, flash DATAFLASH memory device, enclosed in a 28-pin small-outline integrated-circuit (SOIC). It features an extended operating voltage range of 2.3 to 3.6 V and is available in two temperature grades and a variety of package types. It is capable of storing 512K bytes of data or program code in an array of 8K pages, with each page being 528 bytes. The memory comes with an onboard 10-bit serial port and is designed for use in systems requiring data storage with access times of 70ns.

The AT45DB041D-SSU is used in a wide range of applications, such as digital voice recorders, digital cameras, PDAs, toys and embedded applications. It is also used for data logging, data security and authentication, firmware distribution and secure data storage.

The working principle of the AT45DB041D-SSU is quite simple. When data is written to the device, it is encoded in its internal memory page formats. To read data from the device, the user must supply the address of the desired data, which is then read from the internal memory page. Once the data is retrieved, the user can manage it according to the application’s requirements.

In conclusion, the AT45DB041D-SSU is a non-volatile, low-power flash memory device, which can store 512K bytes of data or program code in its array of 8K pages. It is used in a wide range of applications, such as digital voice recorders, digital cameras, PDAs, toys and embedded applications. It works on a simple principle, where the user provides an address of the desired data, which is then read from the internal memory page.
