Application Field

The SST39VF401C-70-4C-B3KE-T is a 1Mbit x 8 32 pin Flash memory which contains 8,388,608 bits of memory and is organized as 1,048,576 words by 8 bits. It is packaged in an industry standard TSOP-32. This type of memory makes an ideal and low cost solution for computer system upgrade and can be used for various applications such as Digital TV, Set Top Boxes, Automotive and Industrial control. This type of memory is also suitable for various storage applications such as disk arrays and RAID controllers.

Working Principle

The SST39VF401C-70-4C-B3KE-T works on a ‘Serial Access’ method, meaning that the data is input or output one bit at a time. The memory has 3 Control Functions and 7 Internal Registers. The Internal Registers include control registers for configuration and two different addresses for instruction and data. The RAM and ROM portions of the memory are accessed in a similar manner and are easily interchangeable within the same space.

The memory implements an Error Correction Code (ECC) algorithm which enables reliable data transfer. This algorithm checks each data block both before and after writing, and is capable of detecting and correcting single-bit errors. The availability of the ECC algorithm makes this type of memory suitable for data-critical applications.

Features

The SST39VF401C-70-4C-B3KE-T offers many features which make it suitable for a variety of applications. Some of its key features include:

• Low power consumption: the device has a low power consumption rate of 70 mA, making it an ideal choice for battery-powered applications.
• Fast access times: thanks to its fast access times of 70ns, the memory performs well in high speed applications, reducing wait time for response.
• High endurance: the device has an endurance of 100,000 write cycles, meaning that the device can be used for long periods without needing replacement.
• High reliability: the memory has an error detection rate of 1 in 10-4, meaning that the data is safe from any type of errors.
• Industry standard package: this type of memory is offered in an industry standard TSOP-32, making it compatible with most standard boards.

Conclusion

The SST39VF401C-70-4C-B3KE-T is a 1Mbit x 8 32 pin Flash memory which is ideal for computer system upgrades and storage applications. It offers many features that make it suitable for a variety of applications, including low power consumption, fast access times, high endurance, high reliability and an industry standard package. Thanks to its error correction code (ECC) algorithm, this type of memory is suitable for data-critical applications.
