IS25LQ025B-JKLE Application Field

The IS25LQ025B-JKLE is a versatile memory device used in a variety of applications. It is typically used in embedded systems, including home appliances, automotive, healthcare and industrial control systems. It can also be used in audio and video applications as well as digital displays, game and DVD players. It provides a non-volatile memory and is a reliable solution to be used in file systems and data logging.

IS25LQ025B-JKLE Working Principles

The operating principle of the IS25LQ025B-JKLE is based upon the principle of non-volatile EEPROM memory technology. The device stores information in blocks of memory cell assemblies, of which the IS25LQ026B has five capacity densities. It uses the self-timed programming and erase operations for both write and read operations, consisting of Program, Read, Erase functions and Reset. Spikes or transients in voltage have no effect on the memory, providing reliable performance in harsh operating environments.

TheWrite operation starts with a program command. Data is written to memory cells via a “Page Program” operation or a “Byte Program” operation. A single byte is programmed in the byte program operation and up to 256 bytes can be programmed in the page program operation. After the programming sequence is completed, the memory is ready for read operation.

TheRead operation starts with a Byte mode Read operation. After the address is supplied along with the read command, the internal chip select is disabled, and the data is available at the output. The Read operation transfers serial data serially out of the device. All the data bytes can be accessed serially from the target memory location.

TheErase operation starts with an erase command. This command initializes the status register for any operation related to erase/program operations. The data stored in any FLASH memory can be erased using this command. The system can then enter Reset command to re-initialize the device.

Conclusion

The IS25LQ025B-JKLE is a reliable and powerful non-volatile memory technology providing 256 Mbit capacity. This single power supply memory device features ultra-low power consumption and is a popular choice for home appliances, automotive, healthcare and other industrial control systems. It comes with various features, including write protection up to 128 Kbytes, program, erase and reset in 100 μs, minimum byte write time of 250 ns and more. The working principle is derived from the principle of non-volatile EEPROM memory technology. All these features make IS25LQ025B-JKLE the memory of choice for many applications.
