The IS62WV1288BLL-55QLI-TR is a memory chip from Integrated Silicon Solution Inc. (ISSI), a company that specializes in the design and manufacture of high-performance integrated circuits for the data storage industry. The IS62WV1288BLL-55QLI-TR is a low-power 8-bit, 1-Megabit SRAM chip. It offers fast access times, a wide operating temperature range, and multiple chip enable functions, making it an ideal choice for a variety of applications.

Application Field

The IS62WV1288BLL-55QLI-TR is commonly used in consumer and consumer- or industrial-grade embedded applications, including remote controllers, measurement equipment, and other devices. Its combination of low power consumption, high speed and wide operating temperature range makes it well-suited for these types of devices, as they often require fast data access without high power consumption. Additionally, its array of chip enable functions makes it suitable for multiple usage scenarios, allowing the user to adjust the chip\'s access speed, enable or disable data output, and more, depending on the application\'s requirements.

Working Principle

The working principle of the IS62WV1288BLL-55QLI-TR is based on the organization of a synchronous and dynamic random access memory (SDRAM). It is an asynchronous interface, eight-bit wide device, where the user is allowed to read and write a single 8-bit word at a time. The maximum access time for the chip is 55 nanoseconds.

The chip consists of an array of 16 rows by 128 columns, and each cell holds 1 bit of data. During a read cycle, the data stored in the memory cell is transferred to the corresponding sense amplifier, which amplifies the signal and sends it out to the output bus. The cell address and the data output are controlled by the chip\'s address buffer and sense amplifier multiplexer. During the write cycle, data is written in the selected cell using the amplifier multiplexer, and afterword the cell is addressed again to read the written data.

The IS62WV1288BLL-55QLI-TR also provides several additional features. It offers a flexible chip enable architecture, with options for one-, two- or three-chip enables. It also provides an error correcting code (ECC) for ensuring data integrity, and an automatic sleep mode for power conservation.

Conclusion

The IS62WV1288BLL-55QLI-TR is a versatile 8-bit, 1-Megabit SRAM chip from ISSI. It is used across numerous consumer and embedded applications, and offers a variety of features, including fast access times, a wide operating temperature range, multiple chip enable functions, an error correcting code (ECC) for data integrity, and an automatic sleep mode for power conservation. Its combination of low power consumption, high speed, and wide operating temperature range make it an ideal choice for any application requiring fast data access without high power consumption.
