Memory is essential in modern computing technology. There are several types of memory available on the market today.
One type of memory used widely is the AT45DB021E-SSHN-T.
Application field
The AT45DB021E-SSHN-T is a type of Flash memory. This memory is suitable for many applications such as embedded systems, automotive electronics, computer peripherals, mobile phones, and other portable devices.
It is designed for low power operation, with its wide voltage range of 1.65V to 3.6V. This allows it to be used in applications where power is a priority. It also has an extended temperature range allowing it to be used in extreme environments.
As it is a form of non-volatile memory the data stored on it will not be lost when power is disconnected. This makes it suitable for applications such as embedded systems where data needs to be stored reliably.
The AT45DB021E-SSHN-T has a simple interface and is easy to integrate into any system. As it is a standardised device, it also provides good compatibility with other components.
Working principle
The AT45DB021E-SSHN-T is a type of NAND Flash memory. NAND Flash is a type of flash memory that stores data in packets rather than individual bits. This type of memory is faster and more efficient than NOR Flash memories.
The AT45DB021E-SSHN-T is divided into pages of 512 bytes. Each page can be written, erased and read. There is an onboard controller to control the memory access and operations.
This memory also uses an onboard error correction code (ECC) which is used to detect and correct any errors that may occur during a write or read operation. This is done before any data is written to or read from the memory, ensuring data reliability.
The AT45DB021E-SSHN-T also has a small sector erase feature, which allows the user to erase small sections of the memory instead of the entire chip. This is useful for applications where only small pieces of data need to be changed.
Overall the AT45DB021E-SSHN-T is an efficient and reliable type of Flash memory which can be used in a variety of applications.
