Working Principle

The AT25DF021-MHF-T is based on the latest 32-P-MOS Serial NVM technology. This device utilizes a highly reliable and low power 32kb Non-Volatile Memory (NVM) Module with a chip enable control. This module is capable of erasing, programming and reading data in-circuit without additional power or programming circuitry. It is designed to work with an I2C serial interface for fast data transfer rate. The AT25DF021-MHF-T also includes an induced sector erase feature for enhanced security options. It is also compliant with JEDEC’s Serial Peripheral Interface (SPI) standard.

With the help of I2C serial interface, data can be written and read quickly, and the data retention time is retained for more than 20 years. At the same time, in order to protect data, the AT25DF021-MHF-T provides various security options and programming algorithms. Data security options include Hardware and Software Data Protection, JEDEC Standard Password Protection, Read-Only Protection and Induced Sector Erase.

The AT25DF021-MHF-T also provides Support for 32k-Byte I2C/Serial EEPROM functions, such as read/write page, random read/write, erase memory sector and other operations. The AT25DF021-MHF-T also supports a large range of operating temperatures, making it ideal for use in extreme geographical and environmental conditions. In addition, it provides with the “Sleep Mode”, which allows the device to minimize the system\'s power consumption and remain in a low power state when not being used.

Conclusion

AT25DF021-MHF-T is a highly versatile, low power and low cost memory device that can be used for multiple applications. It is suitable for industrial data logging and personal equipment applications, and is compliant with JEDEC SPI standard. The AT25DF021-MHF-T also includes several data security and protection options, as well as support for 32k-Byte I2C/Serial EEPROM functions. Along with its excellent data retention and wide temperature operating range, this product provides a reliable, cost-effective and high-performance memory solution.
