AT45DB321E-MWHF-T Integrated Circuits (ICs)

The AT45DB321E-MWHF-T is the latest in a range of memory chips from Atmel Corporation. It is a 2Mbit Serial Dataflash, which provides a reliable and high performance data storage solution for embedded systems. This chip has two different working modes: Bit-Serial and Page-Serial, which are designed to meet different application requirements. In this article, we will explore the application field and working principle of the AT45DB321E-MWHF-T.

Application Field

The AT45DB321E-MWHF-T is suitable for a wide range of memory intensive embedded applications, such as:

• Secure digital cards
• Barcode readers
• Point of sale terminals
• Mobile and automotive applications
• Industrial control systems

The chip is designed to meet the requirement of these applications with its low power and high speed memory access. It also has endurance up to 10 million program/erase cycles and a data retention of up to 200 years, which ensures that it can cope with the harsh environment which embedded systems often operate in.

Working Principle

The AT45DB321E-MWHF-T provides two working modes, which are designed to meet different memory access requirements. The first is the Bit-Serial mode, which can access a single bit at a time. This mode is suitable for applications that require low latency and high speed data access. The second is the Page-Serial mode, which can access up to 256 bytes of data at a time. This mode is more efficient when dealing with bulk data access, making it suitable for applications dealing with large amounts of data.The chip also offers power saving features, such as the Sleep mode, which reduces the power consumption when the device is idle. Additionally, the chip also features an internal power cycle management system, which ensures that the device remains stable in the event of sudden power losses.

Conclusion

The AT45DB321E-MWHF-T is a powerful and reliable 2Mbit Serial Dataflash from Atmel Corporation, which is designed to meet the memory requirements of a wide range of embedded applications. It provides two working modes, Bit-Serial and Page-Serial, which are designed to meet different requirements. It also offers power saving features, such as the Sleep mode and an internal power cycle management system, to ensure that the device remains stable even in the event of sudden power losses.
