Memory

JS28F160B3TD70A is a 16M-bit CMOS Flash memory, manufactured by Intel. It is ideal for high density and low power applications that require extensive data storage, such as computer and communication systems, automobile systems, and portable devices. This article will discuss the application fields, use cases, and the working principle of the JS28F160B3TD70A.

Application Field

JS28F160B3TD70A is commonly used in embedded applications, where requirements demand small size, low power, and higher storage capacity. The most common use cases of this memory includes products like digital cameras, portable media players, PVRs, digital TVs, computer systems, metering systems, communication systems, automotive/traffic systems and medical equipment. This wide range of application fields is made possible due to the small size and low power characteristics of the JS28F160B3TD70A.

Working Principle

JS28F160B3TD70A features a x8 organization, with a low voltage of 1.8V to 3.6V and an asynchronous interface. The memory image is organized in blocks. Each block contains 256 full words. The first 64 bits contain manufacturer and device IDs, as well as revision and function code information. The following 192 bits represent the main memory, which can be programmed and erased in blocks for greater efficiency. The last 32 bits represent the redundancy area, which enables the memory to achieve greater reliability.

The device can support three different programming techniques: word-program, byte-by-byte, and hardware algorithm. The hardware algorithm is intended to reduce programming time. Details of the programming techniques are included in the device datasheet and are available on Intel\'s website. The erase operation is done by bulk erase, also referred to as a flash erase. This operation erases all bits in a given block. The programming and erase operations of the JS28F160B3TD70A are supported by five commands: RESET, READ, WRITE, ERASE and PROGRAM.

Conclusion

The Intel JS28F160B3TD70A is a 16M-bit CMOS Flash memory. It is designed for high density, low power embedded applications. Its x8 organization makes it ideal for applications that require extensive data storage. The device features five commands: RESET, READ, WRITE, ERASE and PROGRAM. Its small size, low power, and high capacity make it a popular choice for a wide range of embedded applications.
