The IS25LQ010B-JKLE is a memory device that is used for storing data in an individual nonvolatile memory chip. It belongs to the family of nonvolatile embedded flash (EEPROM) memories. This is a single-voltage device consisting of 1 megabit (Mb) or 128 kilobyte (kB) of flash memory. The device offers a choice of access time (bus frequency) of either 90ns or 120ns. It has a Serial Peripheral Interface (SPI) bus compatible 3-wire serial interface — Serial Clock (SCK), Chip Select (CS#) and Serial Data Out (SO).

Application Field of IS25LQ010B-JKLE

The IS25LQ010B-JKLE memory device is suitable for a wide range of applications that require a nonvolatile memory solution. The typical applications include gaming consoles, graphics cards, automotive controllers, medical equipment and industrial controllers. It can also be used for updating BIOS (Basic Input Output System) which is the key software of an information appliance.

Thanks to its 1Mb flash memory, IS25LQ010B-JKLE can also be used for storing large data and software in embedded systems such as industrial automation, medical equipment, and automotive systems. In addition, due to its low power consumption, the device can be used for portable applications such as mobile phones and digital cameras.

Working Principle of IS25LQ010B-JKLE

The working principle of IS25LQ010B-JKLE is based on EEPROM memory, which stands for Electrically-Erasable Programmable Read-Only Memory. EEPROM provides non-volatile storage of data and can be written, erased, and re-programmed in-circuit without the need of any dedicated external programming device. IS25LQ010B-JKLE is manufactured using a Single Poly technology for minimum cell size and low cost.

IS25LQ010B-JKLE provides a single-wire three-state Serial Peripheral Interface (SPI). The interface consists of Serial Clock (SCK), Chip Select (CS#) and Serial Data Out (SO). This interface allows the IS25LQ010B-JKLE to communicate with and transfer data to the host while keeping the logic levels at the SCK, CS# and SO pins constant. The device can be programmed, erased and read in byte, page or sector operation modes.

Moreover, the device is featured with two levels of hardware write protection. The first one is a write protection of SPI Write operation, which prevents data corruption if a write cycle is terminated externally or internally. The second protection level is write protection of the whole device. This ensures data protection against accidental write cycles, erasing and programming.}

In terms of power consumption, the IS25LQ010B-JKLE consumes less than 70mA for writing, and about 2mA for idle condition. Furthermore, the 1Mb memory device supports the auto-standby mode and the ?sleep mode? which enables substantially reduced power consumption.

Conclusion

The IS25LQ010B-JKLE is a 1Mb nonvolatile memory device that can be applied to various embedded systems. It features an SPI interface, different access time (90ns or 120ns) and two levels of hardware write protection. Moreover, due to its low power consumption, the device can be used for portable applications such as mobile phones and digital cameras. The device\'s main features make it a reliable choice for applications needing a non-volatile memory chip.
