AT25DF021-MH-T

AT25DF021-MH-T, is a nonvolatile memory with a total capacity of 2097152 bits, divided into 262144 8-bit blocks. Its working principle is based on the serial peripheral interface (SPI) interface communication technology. This nonvolatile memory module is suitable for applications that require reliable data storage and rapid read/write functions.The AT25DF021-MH-T is specifically designed to meet the requirements of embedded systems, especially those with limited space requirements. This makes it ideal for applications such as data logging, data storage, configuration storage, remote system upgrades and others. The SPI interface of the AT25DF021-MH-T allows it to be easily connected to microcontroller systems. It supports several specific commands, such as "read" and "write", among others. The “read” command enables users to read out the data stored in the memory blocks. The user can also specify a start address, data length and access speed. In this way, the user can read out the stored information or perform data management tasks without any complex programming.The “write” command is used to update the data stored in the memory blocks. It is often used to change the address or value of certain data or configure certain settings. This command can also be used for rapid programming of microcontroller memories or for updating the content of application programs. The AT25DF021-MH-T also supports other commands, such as sector erase, block erase, chip erase, and power down, among others. Because it is nonvolatile memory with a write protection chip, it can effectively protect critical data from tampering. In addition to the above characteristics, the AT25DF021-MH-T also has a number of other features that make it suitable for all types of applications. It is small, lightweight, and has low power consumption, making it perfect for use in battery powered environments such as wearable devices. Furthermore, the AT25DF021-MH-T has a maximum write speed of 256Khz in 1-bit mode and 28Mhz in 8-bit mode, which allows users to perform frequent programming and data acquisition operations. With a storage temperature range from -40°C to +125°C, it is suitable for a variety of applications and environmental conditions. Finally, the AT25DF021-MH-T is a highly reliable nonvolatile memory with a 100,000 cycle read or write endurance, 10 years of data retention and 1,000,000 program/erase cycles per sector. This ensures that stored data remains secure and reliable for a long time.In conclusion, the AT25DF021-MH-T nonvolatile memory is a reliable and powerful solution for a variety of applications. Its commands and features make it easy to use and configure, allowing it to be easily integrated into new or existing embedded systems.
